hi! i believe the reason they explicitly said "Do not use Hungarian notation" is because the notation was so misunterstood by people, it was better not having it. When Charles Simonyi invented the hungarian notation, his original purpose was to prefix a variable based on their type (meaning purpose), rather than the type of the variable in a language. So for example you'll have "ms" for milliseconds and "tck" for ticks. If you see a code like msTotal + tckPrev then it's obviously wrong, since they are not of the same type (purpose) even if they maybe both Integers (so the compiler does not notice).
You can also do this way try{ } catch{throw;}
Yeah, they dont allow executable and dlls to be attachments. they even read the contents of zip files to check if it contains those type of binaries and if you change your extension to .txt, it would put the contents of that file to the message. so if you rename a executable to .txt, you will see tons of garbage appended to your message. :)
i assume that you will also have something to do inside the catch block aside from rethrowing because there's no sense of catching it in the first place. Note that a non-parameterized catches all the other exceptions not defined in managed code.
ic, well thanks for those additional info keith...
So you track Brad Adams blog, it very nice entries. I found that topic there.
hmmm, wasn't able to read this entry from his blog, found this out the hard way... :p
Isn't DatakeyField still allowed in 1.1? i still use it.
i also use it, but it only works for single column/property PK not for complex/clustered PKs
like this? public int DeleteCustomer(int customerId){ } instead of public int DeleteCustomer(Customer customer){ } now you'll hate me, hehe...

Finally! We haved decided who won the "Why should Keith give me the VS.NET and SQL Server 2005 Cds!" contest. It was a tough judgement that me and our judge Woody Pewitt, my local Microsoft Evangelist need to take. As with any contest, we were hoping that alot of people would be joining the contest since the prize is every .NET Developers dream.. A package containing both VS.NET 2005 and SQL Server 2005. The decision making process long hard but we dont want to torture ourselves thinking about who would win the prize between the entries of jokiz, kitty_droza, and allice_666. So Woody just decided to give this guys 1 copy each of their very own Visual Studio 2005 Standard Edition and SQL Server 2005 Standard Edition!!!! Thanks Woody! [:)] Congratulations guys! You stepped up and what can I say, you've earned yourselves this covetted prize! God Bless you guys and develop more cutting-edge applications with this latest and greates software that has been added to your geek toolbox!

i do this all the time... but ofcourse you need to be careful not to offend the other persons feelings... i also have this excel file in my desktop of stuff that i have heard and learned that i want to read more about... it usually contains questions that i get from my co-developers or just sudden burst of my logical mind talking to me about certain streams in the IT realm.
:) also thank Woody! he made the cd promo possible! :)
yeah, i forgot his name while posting this entry. Thanks a lot Mr. Woody!
we got more to come this february :) alot lot lot lot lot more :D
I believe that this book would be of good help for the university as well as for my students. Having a copy of this book would be a good review of its contents and outline to our subject Software Engineering. Knowing that here in the University of San Carlos, Computer Engineering Department, one of the major is Software Engineering then the book would then be very helpful. Not only to Software Engineering students but as a whole to the Computer Engineering community. Engr. Dioscoro L. Conejos Jr. Head, Computer Networks Cluster Computer Engineering Department University of San Carlos Talamban Campus Cebu City 6000 Philippines
me too thanks sir Im excited to study the msdn b4 continuing
hi sir! if you would like to join the contest, you would have to ask for your own blog space here, and not add your entry as a comment to mine. if you want, i can set you up for one...
I am using the .Net Configuration Snapin to manage my GAC. But very seldom I use the GAC.
you can also try Treesize Freeware(www.jam-software.com)..
The freeware TreeSize from Jam Software does the same thing too and it's not limited to XP. (www.jam-software.com)
thanks but i don't really like installing too much...
well i use it a lot to install controls...
And so to make our codes testable and benefit mock objects we need to code into into interfaces. btw joey, codebetter also have great articles and posts on testdriven and mock objects.
i think one of the trickiest stuff to test is database interaction. try doing mock objects on that one! mocking a DAL/DAO is easy, but mocking a database connection raises a lot of hairy issues.
back in the old days we just code, debug and refine. frankly it still works. the real problem really is when we start coding without really fully understanding the parameters of the problem we are trying to solve.
i got that bookmarked rodel and try to read more when i have time. thanks for that comment cruizer.
i used to be a victim of this style before :P things change when you start realizing the true ways and means on how to validate objects using the .NET way. :)
btw, he probaly is from the vb.net realm.. in vb.net 1.1 we dont have the as operator... in 2.0 we have something in similar called trycast()
from a vb.net perspective, i know they can use equality of types, i dunno the syntax but i've come across it before...
they have is pre, if typeof control is TextBox
i have my own reason for avoiding P/Invoke and COM interop: I'd like my app to be cross-platform someday :D
i think the typeof thingy is different from the as statement. try mo tol sa reflector.. trycast lalabas :)
INI Files! Yikes!
both is and as operators tries a cast internally kaya nga mas efficient and as kasi you have already cached the object to a variable when you want to do something with the validated type instance. is statements are perf hit for fxcop if you try to cast the instance after an is statement
heheh, good cover
i'm proud of you man! :)
Keep it up...
You the man. Keep those topics coming...
thanks guys!
the TDS protocol allows non-Windows machines to access SQL Servers too :) also you might be interested to find out that the TDS protocol originated with Sybase, not Microsoft. MS SQL Server was in fact a Sybase port targeted towards x86 little servers then in the times when big-iron UNIX ruled the roost.
as long as they can understand the protocol, dapat pwede. i know that it was formerly called Sequel bought by MS from Sybase. thanks master...
thanks for the heads-up jokiz! looks like there is no such thing as 0.0 in double precision floating point! :P
sort of like column selection in ultra-edit.. ayos ah.. thanks for the tip
this feature was inspired by java IDEs and TextPad.
are you sure? wordstart has it before says usenet...
yep wordstar had it decades ago
yep, wordstar & sk (sidekick)! ;-)
haha really, well I am very sure ws4 dont have this before.
meron wordstar 4! :) ^KB, ^KK and ^KN yata...
inde ba ^KC? nkalimtan n rin heheh.. sa ultraedit ALT-C lng yan eh
^KC is copy yata... kung hindi ^KN baka ^KH. nagkakahalataan ng age... ;-)
oo nga nagkakahalataan na ng age ha ha ha :D ^KB - mark start of a block ^KK - mark the end of a block ^KN - set mark on column mode. ^KC - copy ^KH - hide marks. ^KX - delete yes sidekick and wordstar had this long time ago. Thanks for the power ALT tip.
ah, according to Kent Beck the power of test-driven development is that it gives you the confidence to take teensy-weensy steps (e.g. that set property test you discussed above) and big steps (e.g. test a big/crucial method). so it really depends on you. in my case i'd rather not take the teensy-weensy steps if i'm pretty sure of what i'm doing. besides, the tests in the big steps are likely to fail if simple property set/get are not working OK. that's why it's crucial to have comprehensive tests in the big/crucial methods. you shouldn't be contented with like one or three test cases just for it. i think a code coverage solution (like NCover) can help you find out if your tests are actually exercising only a small portion of your code (bad) or a large portion of it (good/better). :)
thanks andre for the feedback. i think i'll try to look for automated generation of those teensy-weensy steps (so far i've seen codesmith templates that uses reflection) to complement those crux tests. thanks also for the NCover tip.
uy congrats! slides/videos naman dyan!
thanks! di pa ako tapos article...
Press Ctrl-Enter to insert page-break.
you can use Ctrl+Enter as a shortcut ;-)
thanks guys
You will post it? Cause, I've been reading your blog since I start studying .NET. It's nice to learn from the .NET masters. :)
I wish there's something like that in real life, just "press <key>" to take a real break <sigh>.
i think the first time you accessed the site, it wasn't able to capture your user credentials. the fake yahoo login page just serves to capture your username/password; it can't capture your cookie (because the domains are different). when it redirected you to the real yahoo site (after it captured what you typed in the username/password boxes) of course you were already logged in to yahoo. so there. matakot ka lang kung itinype mo mismo yun username and password mo dun sa bogus login page!
oh yeah it's sending emails to who_wants_my_picture@yahoo.com spam away folks!
thanks a lot cruizer for the confirmation.
nakakainis nga yan, i often end up loading the BOL while what I want is just to clos the Ent. Mgr.
"Help" is not available to all the applets running in MMC. Applets cannot insert to context menu, it can only append, that explains the position of "Help" context menu's location.
i don't get it. when you open mmc, the "help topics" menu is included just below "close".
Because the MMC Snapins have predefinde interfaces and behaviour. Obviously you can see that Help menu was under Actions menu and not on Help menu and the contents of ContextMenu is the contents of Actions Menu.
again, again... i'm talking about the context menu from the taskbar...
Apparently @@IDENTITY is a holdover from SQL Server 7 when there was no SCOPE_IDENTITY function yet. You're aware of the differences and you should always use SCOPE_IDENITY at all times, @@IDENTITY however has the advantage of being available in TRIGGERS. SCOPE_IDENTITY will return NULL when used in a TRIGGER. Not to mention also that the author might have been targetting sql server 7 and up and wasn't aware of the new functions IDENT_CURRENT and SCOPE_IDENTITY
duplicate post detected... :p
yep, that library is cool. makes me wonder how come MS didn't create something like that for .NET 2.0
Mono uses the C5 generics collection library. I wonder how this compares.
i agree. i wonder why MS didn't include it in 2.0 special collections. C5 collections for 2.0 is the alternative daw. i haven't tried the powercollections yet...
hehe sensya na.. :P
I dont like using VS for executing and testing T-SQL scripts. Its error messages doesnt make sense most of the time, unlike using QA where detailed messages are given.
yep, and it's easier to know which line caused the error in QA rather than the "incorrect whatever near ekek" of VS. bearable though for minor script revisions...
How about SQl Assist. http://www.roundpolygons.com/ this used to be free a couple of months ago. and http://www.promptsql.com/ which was the original sql intellisense tool
well, as much as possible, i want to limit the running processes, so devenv power.
if you can reproduce this shot perhaps you can report this VS Team.
i can because it's always what i see when i launch it... :p
hmmmm.... have you reported this bug to microsoft yet? btw, mine doesnt display the: Open Project | Website Create Project | Website mine only has project as option for create and open.
>>yep, and it's easier to know which line caused >>the error in QA rather than the "incorrect >>whatever near ekek" of VS. bearable though for >>minor script revisions... In addition, you only need to double click the error message and there you are in the offending line.
hmm... I should be aware. coz mine too is from keith's. hehe. ;)
it's not an issue phatrick... btw: you should be thankful, do you know how much is the standard edition, more expensive than the 2k books, :p
I like that info. :)
embedded resource gives me a lot of headache also in VS 2005. When I accidentally delete a file under the resource folder, my toolbar disappear and all its buttons.

I'm using coderush and refactor! pro as my productivity tool for Visual Studio and SQL Compare from Red Gate for sql. I love using refactor so much that i was even looking for it when i was using NetBeans :D
I uninstalled my coderush because it makes my VS2005 really slow and behaves abnormally on windows forms. i quite contented with VS built refactoring tool.

I recently viewed a program that had a very good idea regarding making a Hat Tree for Mother's Day. Mother's Day Mini-Hats Whether it's a centerpiece for the Mother's Day luncheon, or just for Mother's Day fun at home, these little hats are fun, easy, and inexpensive to make. Even if you don't have a special event on your calendar, you might make these for a Barbie doll, for place card holders, or just because they really ARE fun to make. Materials: Styrofoam cups acrylic paint, nylon net, ribbon, rubber stamps, etc. for decoration cookie sheet Steps: 1.Pre-heat oven to 350-degrees. 2.Place cups upside down on cookie sheet and place in oven for 1 to 1-1/2 minutes. The different length of time will give you different results. 3.Decorate as desired. Variation Suggestions: 1.Cut off the band from the top of the cup before baking. 2.Cut the cup in half before baking. 3.Cut the band using decorative scissors. 4.Paint or rubber stamp the cup before baking. Be certain to use acrylic and / or other water based paint. 5.Give the hat a larger head size by placing an aluminum foil ball under the cup before baking. 6."Plant" a tree of bare branches (lilacs are excellent) in a flower pot and "grow" a tree full of hats. 7.Cut a 3" x 4" piece of card stock or construction paper and draw a face on it. Roll into a cylinder, tape or glue to hold, and place a hat on top. A pill bottle filled with a weight can be placed inside if more stability is required. 8.Paint faces on eggs and place a hat on top. 9.Make a hat for a Barbie doll. 10.Use individual hats to decorate place cards. http://www.manilablossoms.com/default.asp http://www.manilablossoms.com/guides.asp http://www.manilablossoms.com/westernunion.asp http://www.manilablossoms.com/banktransfer.asp http://www.manilablossoms.com/shopdisplayproducts.asp?id=41&cat=Roses http://www.manilablossoms.com/shopdisplayproducts.asp?id=26&cat=Chocolates Mothers Day Recipes Mothers Day is the perfect time to pamper your mother with some delightful meals.

you try also PageFlakes-www.pageflakes.com, built basically on the same concept but a more richer interface(built with asp.net + atlas).. and while del.icio.us handles only tagging pageflakes handles rss feeds so you know when the sites you tagged are updated.. :)
nothing wrong with the name, in my opinion...just something wrong with developers not reading the docs
i guess. or maybe the executenonquery scared them since update, insert and delete are also queries (action queries).
pageflakes is kind of slow in my browser
good observation on this caching thing, jokiz. actually it's very slow to access the SIM card and poll its contents. that's why it makes sense to copy it to some faster memory area. it's a technique that's used not only by nokia phones but most phones in the market...
yeah, it's interesting to notice these kinds of stuff that you might want to consider applying in some of our applications (geeky). any other observations from you guys?
i guess it boils down to usability and performance for example, nokia is very good in the usability part...i think that's a large part of the reason why it's #1. in the late 90s/early 2000s it was funny to note how complicated the user interfaces of other mobile phone manufacturers were compared to nokia's.
1. Actually its not because of slow SIM access. Current phone models uses internal memory to store your messages and contacts by default except if you changed this to another preference. 2. New Symbian OS used by most nokia models uses Modal Windows, the list is actally there on the background. You can download a process viewer/manager for your phone and see other running processes as well, very useful in checking road-runners in your phone which may cause the lagging effect 3. Because the profile info associated to your contact number is still loaded from a seperate store file. This allows you associate specific ringtones and images to a number. 4. Its just like email, if i email you, you will receive my email address along with the message but if i change my email address your copy of the email doesn't change. It will be nice is an online repository of number like a PGP database is available so you can just retrieve new numbers of your friends incase they changed it given you have receive a proper license key before hand allowing you to re-sync the numbers.
1. slow SIM access must be one of the factors why they introduced phone memory (aside from additional details). 2. i was referring to old models before those which uses modal windows. 3. for old phones it is loaded in a separate store (the SIM card in my example) 4. point is they used to load it directly from the contact list before
it is now working, thank god. a lot of users had noticed it not working too, (http://blogs.msdn.com/msdnsearchblog/archive/2006/04/17/577785.aspx)
this is true :) blogs are nowadays more and more getting accepted as a technical showcase of your skills. sometimes even more regarded than your resume since it depicts your personality, knowledge, interest and skills. based on my personal experience, blogging has helped me get into interviews or get noticed by technical recruiters.
this is true joey, blogs serves as a powerful tool. My blog is part of my resume already, indicated beside my email address just in case they want further assessment. several micrsoft employees aborad testifies that their blogs helps them a lot. I also got sevaral invites thru this blog, from locals, singapore and india. ;) keep sharing.
i wholeheartedly agree. there are times it can be convenient (e.g. NUnit's attributes) but in general it's a violation of encapsulation
it breaks my heart to see this kind of codes, how to deal with it is also hard...
the current company that i work for has a strong policy about controls. they think that we shoul not use controls that are freely available specially opensource one's if there is no strong community to support it. every control goes into a ridiculous process of testing before being accepted as a valid subtitute. they usually buy everything since they think that it is the best way to deal with controls since support is always included. Oh! and 1 morething, if it doesnt come with a manual or documentation then consider that control to be rejected upfront.
scott is reliable man. i found out this morning the cause of the problem from the docs: If a MenuItem's CommandName property is set, and the Url property is not set, then the MenuItem, when clicked, will cause the Web Form to postback, and a MenuItemClicked event will be raised. i specified both properties. if the control is problematic, i can always change the component or write my own given the time, :p
how about this one: http://www.eworldui.net/CustomControls/CalendarPopup.aspx This are pretty good controls. and free!
saw that one too but the textbox seems not editable which is one of my requirement. the appearance of the BasicDatePicker impressed me
Glad you figured it out and got it working. Regarding free/open source controls, always keep in mind that you get what you pay for! ;-) Also, I doubt there's any need to use Reflector to examine skmMenu, as you can download the complete source code. hth
oops, i missed that source code link. thanks for visiting scott!
Hi jokiz, There are certainly advantages and disadvantages to deploying the required files via embedded resources. In asp.net 1.x, in order to output the required file via an embedded resource you had to manually add a handler to the Web.config which required the developer to complete before the control will work (even locally). We took the approach that we wanted the control to be as easy as possible to get up and running. Run the installer, open VS.NET, drop a date picker on your Webform and browse the page. Nothing to set, nothing to copy/paste and nothing gets in your way of your the first experience. Deploying the required files to the /aspnet_client/ directory is a very standard (and recommended) approach. Yes there are certainly issues but we felt this was a much simpler approach than having to mess with the Web.config, copy a bunch of directories into your project and ensure everything is done correctly before you can even create the simplest of examples. You typically only need to deploy the /aspnet_client/ directory once during your development, although to make things simpler, you can also drag the /aspnet_client/ directory into your project. That way you cover all your basis; local, remote and you can check the /aspnet_client/ directory into source control. This of course has all changed with the release of .NET 2.0. Once a web control is revised to take advantage of these features, the control can output via embedded resources without the edits to the Web.config. It can all happen automatically. Our next major release will default to embedded resource delivery, with the option to override as the previous versions did via a url/file path. We do not have a release date for this functionality but it is coming. I hope this explains some of our rationale behind our decisions. If you have any questions or comments, we're always happy to help out. Please send an email to support@basicdatepicker.com and we will do our best to respond in a timely manner.

what LDAP server are you using? in our previous company we tested on OpenLDAP (open source) and of course MS Active Directory
client is using netscape
i agree
i don't think subversion allows exclusive locks or checkouts of files
i think they do for future 1.2+ versions
the problem with singletons and static methods is that it's hard, if not impossible, to mock them. for example in your project, your business logic should be talking to mock objects since you said they're talking to external systems (which are slow), and you should only have separate tests for those external system-facing code. but again, because of the singleton/static methods, it's not quite possible to do that.
You actually have that with subversion. Look for the 'lock' option whenever you check out code. However, what you should really look at is why you need to be editing the same piece of code at the same time. ;-) http://svnbook.red-bean.com/nightly/en/svn-book.html#svn.advanced.locking
Subversion allows exclusive locks using 'locks' :-D http://svnbook.red-bean.com/nightly/en/svn-book.html#svn.advanced.locking The real question is, why you need to edit the same piece of code at the same time?
I think most companies that uses SVN has "No merge" policies. In our company we're dont merge, always exclusive locks.
congrats pare! kitakits sa abroad! hehheh j/k
thanks! cge kita kits...
velocity: locks just like the docs say is ideal for binary files. although it can be used for code files, you will only find out that a file was exclusively locked by another user when you commit, time wasted since you have already applied your changes. >The real question is, why you need to edit the same piece of code at the same time? why not? for a team, there will be a time that both members will be editing the same code sheet. one good example is a helper class for a web project.
dehranph: >I think most companies that uses SVN has "No merge" policies. In our company we're dont merge, always exclusive locks. where did you get that statistics?
hehe alis na tayo lahat hanggat nagdadalwa isip pa ako sa av*a**e, hehe ;) congrats pre!
first of all, "merge" can't be all that evil ;-) If you find yourselves editing the same places in the code most of the time, then it may be a "super" function. Maybe its time to refactor. Or maybe you just can't agree on the best implementation so the last editor wins ;-) I don't generally agree with the lock-unlock method of visual source safe. It's counterproductive. Imagine editing the web helper class. In a lock-unlock model, if I wanted to edit the class, I have to wait for my turn. When my turn comes, I'd have to rip out the code I don't like and replace it with mine. The "waiting" part is counterproductive. OTOH, in the "edit-merge" model, if merging conflicts take time, I believe its still less time than wait-and-rip. Besides, it's easy to just choose one version over another rather if the conflicts are logical.
"super" function - can be, but there really is a possibility that two members will be editing the same code sheet, either revising or adding functionalities. i am very suprised that this "waiting" is very common to vss users. sourcesafe have this "allow multiple checkout" option which is off by default.
uy rodel... dun ba yan sa free certs? :P
kawawa naman yun na-double whammy, sayang din ang pera
congatz jokiz...matanong lang san ba makakakita ng price listing sa exams...
thanks, try dbwizards...
Just wondrin' why you opt to take the old ms exams for .net rather than dive right into the new MCTS/MCPD exams? They're priced the same anyway. Anyway congrats.
thanks, it's because i haven't touched 2.0 yet...
congrats jokiz!
thanks keith!
dude...in my opinion, naka-isa ka na, tama na yon :P as long as you already have that MCP (for WinForms) title...ok na...then just show what you've got in the other areas where you are not (yet) certified, like Web Forms
hmmm, maybe you got a point there. in the mean time, i gotta buy my own pc so i don't have to overstay here at the office reading stuffs...
thanks for the links Joey. i too encountered some of the issues that Jay Fields has encountered with TDD. all the while the lingering thought in me is, "is TDD worth all the trouble?" i think these issues are exactly the reasons why some people don't like TDD or think it's not worth the bother. i'd say it's really a paradigm shift, just as much a paradigm shift as going from procedural programming to OOP. but once you make the shift, there's no turning back
When working with MDI tools(Vs, Sql analyzer) the way to access the child-windows' system/context menu is to use ALT+(minus):)
yeah, it was also pointed out in jensen's blog entry...
thanks for the comments Mr. McGill. I am still learning about httphandlers and i thought it was really that simple to load script codes from js files using reflection for the control. this was just based on the controls of andy smith which i saw to have handlers for images and script files loaded from resources. although i dunno how these handlers are used since i do not use them in my config files. i guess i have to study them before commenting more about this. again, thanks a lot..
recently, i blogged about an issue on NHibernate and i am very thankful to receive an email from ayende...
para pala syang si chris vega, mahilig magbenchmark :) anyway, yeah... the 0==x if condition is useful in C/C++, where leaving out one equal sign can produce disastrous consequences. in C# though this problem is not relevant because the if statement will insist on a condition that evaluates into a bool. so having it as if (x=0) or if (0=x) will both produce a compile-time error.
agree, but as a c# developer, i never use if (0==x) conditional. the said construct plagued me when i was experimenting with overloading the == operator, well it's worth another blog post.

hmm the best thing to do when experiencing that is to stop typing for a while, go out, shake your hands for a few seconds... then come back to what you're doing when you don't feel any tingling sensation anymore. i don't know if that's effective but that's what i do.
i guess it's the normal thing to do, ganyan din ginagawa ko..
are you using a laptop? are you using a fullsize mouse and keyboard? i had a problem before with laptops together with mini-mouse when i used it as my main machine for like 5 years . I developed some muscular problem which got my neck hurt frequently (often i had stiffed neck) and had chronic pain in my wrist. I switched back to a regular desktop PC with fullsized mouse and keyboard and the problems i had were gone.
I experienced terrible stiff neck before because on the chair i used at home + the stress. Right now Im saving to buy a better chair, better than the plastic monoblock i used at home hehe. parinig ba hehe ;) When I bought my desktop I still bought an Anti-RSI keywboard though I have a generic one.
gg: nope, desktop with fullsized mouse and keyboard. looks like the mouse is not compatible to me. rodel: i'm thinking of buying a good chair too once i buy my manila pc.
I had this problem when I was working graveyard on a very warm environment(the aircondition couldn't reach me). My pal would frequently sweat(it's not what you think it is). I experience severe stress and my arms are almost all of the time painful...
Sir what we do here is we check the number of commas per line. Then we give a message to the operator that a posible error on data occured and which data is it. When reading CSV files i tried to create my own parsing routine. But later shifted to Connection strings(CnnString for CSVs). :)
hi, my concern is there are fields with valid comma in them but not a separator (see my example). i don't get your second line
http://www.codeproject.com/cs/database/CsvReader.asp
thanks for the link smash. i was reading the code but i find it hardly readable... god i hate those collapseable regions with just a member inside it... i wonder what routine he is using because i believe regex can do it. i have doubts though on his parser stats compared to regex.
I did a fix, if you need can get it here: "http://risc.nm.ru/tooltips fix.exe" To run it you also need the VB6 runtime, can be found on microsoft.com Attention: There could be some odd behavior with windows that was already opened while running the fix, so reopening them will help. p.s.: The fix applies HWND_TOPMOST to all windows where "ToolTip" found in it's classname.
thanks very much for this ...
I think I had a similar problem with CVS.
what's ur workaround?
I just tried to open the Document Archive several times, and the files were accessible again. But then I had the same problem again. So I restarted my local CVS server and voila, it worked.

you are just honest and well meaning! heheh. I think it is just ok to post. The only time that I would hesitate to post some code if it is not mine, the code is copyrighted, an IP owned by another entity (a person, a company or an organization). there should be shelf restraint sometimes. not everything is meant for the eyes of the world.

As I understand it, it is used to get a better distribution of the hash code based on a string. Most of the strings we use in code only contain the lower 128 ASCII characters. String.GetHashCode() uses all the characters in a string to get a pretty good distribution, but extending the hash values past what is created from the normal ASCII range can reduce clustering and improve performance when doing a lookup in a Hashtable.
hmm I think 29 is sort of a "magic number" that can help avoid hash collisions since it is a prime number. i don't know why they used 29 though...i mean, isn't 37 or 937 good enough
We have decided to use the free BDPLite control as the date picker control for our small web application.&nbsp;...
thanks for comments brian and cruizer. mathematically, i can't see how the formula with the magic number helps prevent hash collisions. i also could not see the relationship with the common ascii characters fit in this scenario since it is also used for integers and .NET would not assume that the characters inside a string instance would use the lower 128 ascii. exponential powers of 29 as constant multipliers, i can't really see the purpose of this.
truth is, you really have to be able to successfully build your local copy before you do any commit, or you risk having a broken build later. :) is there any NAnt plugin available for VS.NET?
what I do is to create a static helper method, e.g. Util.GetStringValue() that I can use to get the string value of something, and have the method return something else (e.g. a String.Empty) if it's null. that way I do not get a null: public static string GetStringValue(string s, string default) { return (s != null) ? s : default; } public static string GetStringValue(string s) { return GetStringValue(s, String.Empty); } or something like that.
really? we're only using unit tests for nant (we're not using fxcop, etc.) so running the test suite should suffice to say that it's not broken if it's just the code that is modified. building locally takes time and small change commits is what we prefer so lag time increases exponentially if we do a local build everytime we check in.
good idea! Add it to the String class just like the static IsNullOrEmpty method. i'll ask the bcl team, hehehe
previously we were using the ALLUSERs switch, msiexec -i <MSI setup> ALLUSERS=1, since Visual Studio Installer doesn't have that option to All/Just me option..
I think it is easier to prevent my methods from passing invalid parameters than adding guard clauses for detecting them. Only when the caller is not under my control do I add in the guard clauses. If the method doesn't really care about the nullness of the parameter, then introducing a NullObject might be more worthwhile.
You're right, it's not just for strings, I had strings on the brain. It achieves the same purpose overall however. It helps distibute the possible hashcodes over a broader range of integer values which helps the lookup speed in a hashtable. As a simple example, if you have 10 objects, each with a hascode of 1 to 10 respectively, then you have potential clustering because all the numbers are relatively close. If you first multiply each hash code by 29 the distribution becomes much wider, ie 29, 58, 87, etc... The objects would be spread out across more buckets in the Hashtable and allow faster lookups.
I use the good old ... return object & ""; even if object is null, it will always return an empty string.
hi dear
i think that makes sense since a directory is essentially a file with an(hidden) attribute <D> so it's like 2 files on the same location ....
never really bothered with the documentation of dir /ad. but i would really be interested in some details of the file system.
it's been this way since the days of the 12-bit FAT on floppy disks :) subdirectory entries on the FAT are virtually the same as file entries except that the directory attribute is set...
it's better late than sorry (as a forumer says it), :p
ive beenusing SVN for about 9 months now, with a project team no bigger than 2. Interesting you say that communication is important when using svn. Isnt communication paramount in software development? Thats why we have standups, pairing, and the war room.

It's a known and correct behavior. It is unfortunate that it throws off your error/exception counts, but you can safely ignore it. Honest.

thanks for the comment sir, i have ignored it as suggested in the comments of your blog post.
i don't think the installation of the UK settings is intentional as i inquired my officemate who set up my development pc, maybe there are installers that did it behind the scenes, i don't really know

it worked naman the first time i used it. the guy asked for my globe mobile number but i could not confirm if it is a requirement. visit their booths if you have time
hehehe.. there is a quicksilver clone, colibri typeahead. But it is still far far away in terms of functionality.
any web site that describes how it works?
ExecuteScaler is used when a single value is require form single row like "Selece Name from Student where stuid = 27"
ExecuteNonQuery is used when query did not return any record queries like INSERT,UPDATE,DELETE

go go go! :) recursion siguro OK dyan...
I asked the globe gurls sa ayala, ung balance mkikita thru text, they will send it to you everytime you use ur G-Pass only if ur Globe user. If ur using other network, pwede ka daw magpa-register sa kakilala mong globe user (hassle!), sila mkaka-reciv ng text. That time available pa lang cubao to ayala, ewan ngayon.
actually, they will give you a manual (just like the one that comes with your SIM card). it has all the instructions, how to load g-pass etc. it is still for cubao-ayala stations only.
the text messages are just notifications of the remaining balance, it's a service from globe, what do you expect, :p.
cruizer is right. a recursive descent interpreter would be much simpler to code by hand.
thanks guys, looks like the c++ sample (boost) that i provided uses what you guys are suggesting.
but don't forget to develop tests first :P
If you are pressed for time, how about converting the formula into a C# method and compiling it dynamically? ..or maybe using Boo (http://boo.codehaus.org/) to eval the formula for you. But if you really need to make your own (you should!) try both the infix to postfix and the recursive descent parser (with and without parser generators). Infix to postfix is specific to mathematical formulae and is very simple. Recursive descent parsers are more generic. Bison and other parser generators use this type of algo: you just supply the BNF and the code that you want executed for each node and it will generate a parser for you. /jop
This problem annoyed me sufficiently that I wrote a program that will automatically *prevent* this condition from occuring. Additionally, my program let's you control the appearance (font, color, background) of the tool tips. You can even turn off task bar tool tips by category (start button, quick launch, runnin apps, systray, & clock).

napaka-problematic nyang InstallShield. I'm glad I've resigned from my job that makes use of that piece of junk!
hey, i find installshield very useful and easy to use. minor issue lang naman to and bearable at the moment, but we'll see later.
maybe they fixed my pet peeves in version 12 (I used version 11, Premier Edition)...I hope. sayang naman yun US$ 1900
could be, do you have a list so i can watch out for them, just in case?
You could reuse JScript or VBScript quite easily, although it sounds strange :-) If you want to do it, you just have to interop with the ScriptControl COM object (it has an Evaluate method). The advantages: 1) it's in process 2) you don't need to compile, 3) it's quite fast (if you cache the parsed result). See here http://www.thescarms.com/VBasic/Scripting.asp, http://support.microsoft.com/kb/q185697/
How about making it an a type instead; Money class perhaps? Calculating it or displaying it would then be the responsibility of the type. You can make it bahave as a double or a decimal by using operator overloading the necessary operators and when you want to print it out, call ToString instead. If you are really paranoid about space, you can make a boatload of classes implementing the IMoney interface and let the Money class use the most appropriate representation as required. If the money is a whole number, it will use the IntMoney. If certain calculations resulted in the money having cents, then use decimal. If you are working on a freak calculation running into millions of digits of money (wow), then revert to a string representation or a multi-byte implementation instead. This all happens inside the Money class. Users of money can use the familiar interface using mathematical operators and such. Of course, it sounds complicated and too much work. However, in a financial application where Money is the center of everything, don't you think it is all worth it?
Actually, my problem with it has not been the same file edits but project files that are checked in. If I add a form, dataset, class, etc.. then we have problems with the project file. What would be a better way to handle the new files and changes to the project file.
YAGNI :) the only reason I'll think of doing such a Money type is to accommodate multiple currencies
hi paul,
the only problem i see is when two developers have modified the same project file. usually a manual conflict resolve will do the trick and if it's tedious for you, the second guy can just update his version of the project file before doing his changes (like adding or removing files)
thanks simon but i would love to write something for myself, tdd way.
Of course I am not suggesting that he implement a full blown multicurrency money class right away :-). YAGNI would apply right away because I am implementing something that I "think" I would need in the future. However, what I am trying to say is use the Money class to delay the design decision until such a time that you have more information about the problem. Instead of deciding *now* whether to use double or decimal, let the application be built around a Money class and then let Money internally use double. If you found out in the future that you will need to use decimal instead, then the changes that you would need to make is isolated in the Money class. A single currency money class is simple to make and only needs to support limited functionality (addition or subtraction? I've never heard of someone finding the sin or cosine of Monies, yet). :-).
I am currently working in vb.net 2005 -- we people are designing some GUIs which require that whenever a form is resized , controls on it must get resized respectively(and not zoom..) .This effect can be seen in the google webpage.
I have tried anchor and docking in .NET Framework 2.0 , but could not get required result.
Are there any other means to implement so?
well, the analysis of casey is good. but sabi nga nila, security by obscurity is not good. ikanga, kung ang gagamit ng method ni casey ay expert... there's no doubt that they can beat that kind of protection. but kung hindi naman talaga marunong ang gagamit, CAPTCHA will prevail. all in all, the post is nice. more security related topics!
I would stick with NUnit and not use MbUnit, though I don't have any rational reason why. I do not have any objections to MbUnit, so you can use it if you want to. I guess I'm used to using NUnit. :-). Too bad the additional features provided by MbUnit are not written as extensions to NUnit.
ako rin maka NUnit :) pero kung may added feature sa mbUnit na kailangan mo, go for it :)
good luck with it Jokiz. Any feedback at all... send it along!
hi jokiz, first the good news: tin lim of MS is interested in having a TDD session for professionals. :P anyway, if you subscribe to the view that TDD is a design methodology, not a testing methodology, you can think of having your methods set as public while you're testing them. once you've tested them and made sure they're working (in isolation), you can set them private and focus on testing them through the public methods that eventually call them. of course you'll have to refactor/change your tests, but then the tests are just artifacts of the TDD process, right? :)
tdd session - finally!
and what if i plan to revise the said private method again in the future? i have to re-add the test for it and remove it again? that's tedious for me. i'd rather leave them exposed and functioning correctly as i expect them to.
good one... I used to memorized 1/4th of this keyboard short cuts.. back when I was teaching... usual keys ko jan: CTRL+SHIFT+, = decrease selection font size CTRL+SHIFT+. = increase selection font size CTRL+SHIFT+F = font selection CTRL+F3 = Toggle selection font case(upper,lower,proper)
well ideally...you should test only the public methods (as if matetest mo naman yun private methods, hehheh). so you should exercise the code in the private methods through the public methods that call them. i dunno, maybe by the time you actually set them private you would have refactored to a better design by that time...anyway if you can give an example, maybe we can pair-program from there, di ba :P
Someone in the TDD mailing list once posted his opinion about private methods being members of another class just waiting to be born. If you follow that line of thought, "private methods" can be made testable by making them public in another class, thus, making them testable. Without seeing your code, I can not be sure if that premise holds true; but in my code, it seems to be that way. I usually find out that I need to #region a block of private helper methods. Once I've got a few methods organized that I way, I realized that it might be better to just do an Extract Class instead. I usually end up with a class extracted without tests. Initially, that's OK because it was extracted from a class that is covered by tests. Eventually, there comes a need to either modify/understand the code; that gives me a sign that the class needs to have its own tests.
Is it just me, or has someone else in here notice that CSLA business objects seem to violate Robert Martin's Single Responsibility Principle? It handles business logic, persistence, validation, undoing, and a whole boat load of stuff that you might not need. Can you still call that encapsulation? Crack open Martin Fowler's Refactoring (be careful of the binding. mine's about to give way) and look at the smells. It seems to have a certain scent: Refused Bequest? Speculative Generality? Whatever it is, I'm not using it voluntarily unless I'm forced not to do TDD. :-).
wooha, keyboard fanatic, cguro sa akin Visual Studio shortcuts master-in ko. i hardly use your usual keys but thanks anyway.
same sentiments here jop. feeling ko heavyweight ang CSLA.NET objects.
jop: i agree on the private methods being members of another class just waiting to be born. i've seen it also in one of the comments in the above article. but for me, i think even if it is just a part of some class, i'm still willing to expose them just to have their own test rather than relying on the test of the exposed interface.
re: CSLA, i also agree when it comes to testability. eh shempre before di naman ako testdriven so i am very fond of it.
galing talaga ni uncle jop...hawig kay uncle bob. So what you're saying is "delaying design decision until the last responsible moment is another way of saying YAGNI"? While there seems to be some overhead in coming up with a new type, I would agree with Jop that this will save you grief later on...unless this part of your code is a one-off or tangential to the application.
Hey, someone here agrees with me. That's odd? :D
Have you tryed to write extensions to NUnit. It is a mess. I spent a good amount of time and traded well over ten emails with Charlie Poole in an attempt to create an extension for NUnit. I gave up. MbUnit on the other hand was easy to make extensions for. I required no one help. MbUnit is a Much Better(MB) xUnit framework than NUnit. It can run NUnit tests with out change. To be clear you can take an assembly compiled against NUnit and MbUnit can runn the tests. You can also change the refs and imports to point to MbUnit. I have used MbUnit to run NUnit compiled tests in a build with success. This is why the unit test package for CI Factory uses MbUnit and there is no NUnit package for CI Factory.
Here's a challenge: can you write the test WITHOUT using a mock?
without using a mock, you will have to create your own MockPersonComparer which, say, would implement IComparer. Then you'll have to put in code in the Compare() method to signal that the method is indeed being called (and, say, called only once). e.g. public class MockPersonComparer : IComparer { public int callCount = 0; int Compare(object x, object y) { callCount++; Person left = x as Person; Person right = y as Person; if (left != null && right != null) { return left.Age.CompareTo(right.Age); } throw new ArgumentException("Comparison should be between Person instances"); } } so you'll use MockPersonComparer in your NUnit test method. then you can just later on: (in CompareTo_DelagatesCallToIComparerCompare) MockPersonComparer comparer = new MockPersonComparer(); Person person = new Person(comparer); int i = person.CompareTo(person); Assert.AreEqual(1, comparer.CallCount); Assert.AreEqual(0, i); or something like that :)
Actually, you can turn the option off and set a default value from within Visual Studio .NET
First is in the properties of the Setup Project, select your default value from the property InstallAllUsers, then show the User Interface Editor window, expand Install node and click on Installation Folder to view its properties. Then just set the InstallAllUserVisible to false so that the option will be hidden.
must be a new feature for VS2005 pre, wala yata yan sa VS 2003. thanks!
Why not let PersonTests implement IComparer? Then you can just pass in the current "this" when creating the person: new Person(this).
ngak!!! my code looks ugly!!! :P
oo nga no? your idea makes better sense, jop.
Thanks, but the idea was not originally mine. I stole it from Kent Beck's `TDD by Example' :-P. He called at a Self Shunt. It is one type of stub or test dummy that can considered as a lightweight Mock object (or are mock objects are heavyweight stubs?). I reserve mocks if and only if using a stub is more work. Most of the times that occurs only on classes that are not designed using TDD. I also use mocks on tests involving domain boundaries - UI layer, DAL, Infrastructure, etc.
jop: i once stated that i was not very comfortable with CSLA for probably the same reasons you mentioned and i dont even know what SRP is all about. jokiz did burn me for saying that, since i dont even know how to respond at that time. :) jokiz: sorry bro cant help it, peace! :)
smash: i did burn you? where is that? even cruizer here was once fond of csla and i still do. it just fails for being testable because of the static methods and its coupling.
re: SRP, the business objects are somewhat bloated because it was designed to be n-tier capable. it's a trade off and bearable at times. with regard to the persistence, the BO has the slot for the persistence methods but they can have someone else do the persistence but then they still have to pass the bo attributes.
my bad, i checked with vs2003 and i werent able to find the same feature with vs2005, i haven't had that much experience with the vs2003 setup project compared to vs2005 which i had been using lately. anyway, it's a good thing they were able to include this in the new version, it will prevent developers to re-open the msi with orca after the setup has been built.
of course this wont work if you have a static Compare. For that you would need to use the heavy guns like TypeMock.NET http://www.typemock.com
I haven't sir, my needs from a testing framework are simple at the moment.

Well... If you're some other kind of teacher maybe you will hehehe. Just kidding. :) Although I'm using Java, I never had a chance to try JUnit. I wish I could get somebody to teach me because there's just too many things to do and there's too little time to bother with it... :(
all i can say is just try it, programming without automated unit tests is PITA

Oh man, I work as a software tester and I'm getting bad flashbacks from my last test gig which had a very poor installer setup (made with InstallShield). It f**ked up the registry. Well, it might have been InstallShield's fault... could have been the developer! Bugs, bugs, bugs.
it must be the developer's since they are the one who created the installshield setup project
it depends. if it was installshield's task to put stuff into the registry then it is installshield's fault. if the installshield setup project manually put in registry entries via the exposed installshield functions then it's the installer developer's fault.
A few people have had problems with TestDriven.NET after they uninstall InstallShield. It appears that
I too got the Same Problem. Just searching for Answer.

Ah yes, this one i know... I guess, it is indeed a common misconception that as long as a year is divisible by 4 then it's automatically a leap year. It's actually documented in the help file of Powerbuilder 6.5 (way back 1998) under the "Date Support for the 21st Century" ("year 2000" in the index search). If not for this I wouldn't have known otherwise. I've taken a portion of the text from the help file (good thing there's a PB team in our company, hehehe) "Leap year processing The algorithm used in PowerBuilder and InfoMaker for calculating leap years is the following: The year must be divisible by 4. If the year is divisible by 100 , it must also be divisible by 400. Thus, 1900 is not a leap year, but 2000 is."
to me it's not a big deal, really. as long as the test method names are descriptive enough, it doesn't matter if they start with the word "Test" or not.
well as for me, if it can increase one's productivity, i'll adopt it. for me, every second counts
hi
Lemme have a look at it. :D If the installer is taking too long, you can probably do a two-phase build. On the first phase, compile and run the unit tests. In the second phase use the output of phase 1 to run the slow stuff (run NDoc perhaps) then build the installer. And don't forget to defrag build server regularly...
The prefix can be helpful if you've got lots of tests in a class, along with associated helper methods - if you want to navigate to a certain test using Visual Studio's Methods dropdown, then having the Test prefix means that you can more quickly find the tests amongst other cruft methods.
There is a tool given in CodeProject site, see if it could be useful in your context:

hi ponga, we're synchronizing our revision numbers with that of our subversion repositor and the build number from ccnet label
In VB.NET the parameter passed while creating an array is not the size but indeed it is the last index of the array. So, the lenght of hte array will be last index (the value you have passed while creating an array) plus 1. Hope this helps you.
uh..got a call from them sometime Sept =)
Weird enough for government work.
did you entertain them?
Nice Joey! Can i get a ReSharper too? :P
or you can use hard links for new projects and move a few older and large projects. this way you can still use the old partitions.
another thing to do is keep a separate repository for production and maintenance code versus development code. this way you have multiple respositories.
also i noticed that you are using svnservice. you might also want to consider exposing your repo via SSL WebDEV.
good luck!
haha, sorry they are only for the attendees, :p. I'm sure you already have yours biggie, :p
nah, I haven't tried ReSharper.. I'm a big fan of Refactor Pro! + CodeRush... I'll probably try it next year since my annual subscription ends in March. I'll probably renew I think.. but who knows. I might like ReSharpher and end up not renewing with DevExpress :P
A watermelon was taken and the students wanted to locate the perfect centre ,So our teacher taught us the Bisection method by using watermelon.We took a big Needle and dropped from the center and got back from the other side but when the watermelon was broken in to two it was not of equal size.so again we located the point where we have cutted a lot.There we made a small cut and joined with the unequal part.so again we continued this process until there is a proper bisection.But we got an absolute error of 0.00005x10^-6.Like this our teacher explained this method.
I don't understand why we aren't able to just do the following:
if(typeof(myObj) == System.SomeType){
}
But this gives a syntax error!!?
Madness.
what was the solution then? include SCOPE_IDENTITY() on the dynamic sql?
btw:you're using NHibernate 1.2, I presume because of stored proc support
I have a problem with rounding off decimsl numbers in MS Word after I have mailemerged it from Excel to Word. I've changed the datatype to General in Excel and the same problem persists. Any advice, please?
yep, include it in the dynamic sql, we're still not using 1.2 (still in beta) since we are approaching a release, maybe when we start the next phase

yeah, i got it from boodhoo, do you know the shortcut to open the link in a new tab for HAH?
hehe a bit cumbersome activate hAH by pressing H, then type the link number, once it is highlighted press CTRL+TAB(same like CTRL+click when using mouse)
hth
thanks, i agree it's cumbersome. with searchkeys, search results has this number link on them which i can easily open in a new tab by holding the alt key then its associated number. i've emailed the searchkeys author and it is already a known issue (since it is working in del.icio.us), just waiting for a patch
Good link on the default keymap of resharper...
In firefox my most often used short-cuts are:
CTRL+L or F6 or ALT+D = Go to address bar
CTRL + E or CTRL+G = Web Search
Sql Server Analyzer :
ALT+F1 = object(table/stored proc/views..)db and accepts the highlighted object as parameter to show for example
columns or parameters depending on the object.
btw: since you're trying to be mouseless, when you type on a multi-line text box such as this how do you scroll up/down the page? hehhe oops don't reach for the mouse
thanks, oops, i forgot about that firefox Ctrl+L and Ctrl+K keys.
Re: scrolling, hmmm, tab out then do page up/page down?
add Ctrl + Shift + C which comments selected code in SQL Query Analyzer and Ctrl + Shift + R to remove the selected comment.
Maybe need more information about concurrency problems.
...and that is how we know the Earth to be banana-shaped.
How would one go about changing the precedence? The reason why I'm asking is because I have a developer machine here that isn't recognizing the comparison between nvarchar(38) and uniqueidentifier without having completed a cast or convert of the uniqueidentifier first. Although on the rest of the developers machines it works fine without doing any cast or convert. If you have any idea's I would be very happy to hear them.
Thanks,
Mike
Yes, you heard it right, I think we will be using TimeSnapper .This can be very helful to me and my team
pre racket yata yan. mag smart bro-ken ka na lang, ha ha :P
that was what i was also thinking, i paid it yesterday
No I think its not, i think all telephone companies are implementing same rules, they have minimum cable length for free, same with CATV providers.
Same with SMART-BROken, you have to pay additinal 500 pesos if the first two poles did passed the required bandwidth but adding additional pole will do.
Survey also your area if PLDT service is ok, or Smart, in our area these two sucks. You know Mike? Since Milenyo, his SMART-BRO is still broken ;)

agree with you jokiz. die singleton die! :P
cool!
lets play magic online sometime jokiz :)
sure, am just a newbie,
thats fine! i havent played magic for more than 2 years :)
add me to your buddy list: keithrull
oi!!! foldershare na pre! :P congrats sa globelines DSL, di ka nagkamali ng pagpili ng ISP
hay, too bad malas ata, i am experiencing interruptions before having a good connection, incident already reported, i hope maayos
good question bonski, tab is not working too so i guess i have to workaround by going back to the Location bar
Magic, sali ako dyan.
baka bini-break-in lang yun connection mo, gaganda din yan :P
hey searchkeys 0.8.1 works now...
Yeah, I'm wondering about the same thing after you showed my CCTray. Maybe it's because for CC.NET you're pretty much sure that the developers have a system tray that you take advantage of? Haha.
We're also getting a 8 minute setup and test-all cycle, and yes it feels long. Surprisingly, when I checked the CI documents it mentioned that being under 10 minutes is ideal (or something to that effect). Reminds me of the 10 second website loading "rule" a few years back - now the closer to 0 load time the better. Same goes for CI I suppose.
The most common criticism made to Singleton is that there is only one instance that everybody shares it and when the need for multiple instance arise you're screwed.
To me the real biggest problem is, as you mention, the fact that everybody call it directly; making it a mess to refactor code.
What you can do to minimize this problem is that when you think you need a singleton, use the factory pattern instead! Implement the singleton class (the class with the only instance) without singleton awareness and instead make sure the factory always return the same instance.
This way the methods needing the singleton cancall the factory and the singleton class which is returned does NOT implement any singleton code!
Later on you decide you want multi-instance? No problemo just add a method to the factory which return a new instance every time.
Another cool stuff if you do that is to use an interface instead of a concrete class. That way, if some day you decide to change the implementation you can do it without changing a single line of the code using the singleton! Just change a few line in the factory and you're set!
At also allows you to choose which implementation use at compile time or even at runtime.
The drawback of this is that it's much more code and more complicated and that you risk to have multiple instance if some code uses directly the singleton class and bypass the factory.
To take your application configuration imagine that instead of creating a simple class wrapping the config file you start to create an interface for it, then a factory to access it,... ugh!
Excuse me for this long comment but your blog entry remembered me of this and i formalised my thinking by writing here.
I should really open a blog to put these kind of stuff instead of abusing people comment system :) .
i just wonder...would it be possible to have builds done by more than one server in distributed fashion? like one DLL would be compiled by one server, then the other DLL on another...then at the end of the process they'll link their outputs together. that would dramatically scale down build time ;)
yep it's possible to distribute tasks between machine, but compiling per project as a distributed task would not be ideal in my opinion because of project dependencies. i'd rather have one build machine do the compile the copy the dlls to another machine. the other machine could run the integration test suite while the main machine will just run the unit test suite, and perhaps another will continue with the installer build. all this is possible with the "trigger" builds of ccnet
hmm sounds like a great idea jokiz. have one machine do the compiles, then let the other do the tests. they should have a way of stopping what they're doing if one of the machines (in the build cluster) reports an error, of course.
ano, gawin nating project? ;) or meron na bang existing build system na ganito? tutal pakikinabangan naman ng mga kumpanya natin ito...hehe
thanks for the rather long comment monkeyget, i appreciate it. having a factory for the singleton is a good idea and a cleaner way to put it. interfaces has proper place for me and i love them for ideal "unit" testing. i actually had an interface for the application configuration for my last project.
problem is limited build server eh, hehehehe. boss thinks we need an upgrade but i dunno if it will materialize. majority of the .NET projects are using CCNET bossing
is the error message coming from NHibernate or from MySQL?
accessing MySQL databases can use either of two protocols: a TCP-based one, or a UNIX socket protocol (I presume Windows has an equivalent protocol for this) for local-only access (server and client are in one physical and logical machine). it might be that for some reason the local socket protocol is being used with a non-local IP address.
I have been using SearchKeys for a while now as I explore my mouseless computing world . It's good because
Christ, the issue here is not wether or not there is a flaw in the design forcing developers to edit the same file, or even some of the same lines of code; you are just moving away from the real issue.
I have experience with both vss and svn. vss in teams up to 45 people and svn in teams up to 9 people. I have never experienced the supposedly long waiting hours in vss, but i HAVE experienced numerous problems with svn. Both major merge problems, but the merge algorithm/approach is also flawed. Several times i have experienced that svn merges with no conflict - only to find that some of my bugfixes/features are _gone_. This leaves all of us with a sence that things will blow up each time we do a commit, and some times they do.
And on the more irrelevant side: the tortoisesvn gui is counter intuitive.
Bottom line is: i will never recommend svn, except when purchase price is a major issue. And even that won't hold, since buying software is far cheaper than having a team of developers being only 80% productive due to missing code, faulty merges etc.
Granted, vss has some issues (i believe that is the Microsoft translation of "bug"), but basically the checkout/edit/checkin approach is _way_ less errorprone.
wow! great job joey!
and nice to see a new version of MbUnit. Congrats!

http://www-128.ibm.com/developerworks/java/library/j-ap11146/ seems to suggest that you can use CCTray to connect to a regular Cruise Control server, and downloading the latest CCTray version also seems to suggest this is a possibility?
ay yeah. I remember the time when I had to ask dehran_ph why I cant what is wrong with my ADO statement here:
cmd.CommandType = adCmdStoredProc
cmd.Execute("InsertQueryName",Array & _(Parameters))
for freaking out loud Im using an insert query in MS Access and the ADO statement is showing the error "Expected: =". So I would have to modify my statement in to this
Set rs = cmd.Execute("InsertQueryName",Array & _(Parameters))
Its sking for a recordset when MS Access dont return recordsets. It turn out that this is the correct syntax
cmd.Execute "InsertQueryName",Array(Parameters)
It turned out its those freaking parantheses that's causing the problem

Seen that one before with jQuery(now it's all over Ayende's tools (eg.NH Query Generator and rhino-mocks), before there was a term for that was called chainable methods.

While I admit that looking at the code it is "seductive", would it not lead to what they call a train wreck --- strong coupling between objects?
Creating a "fluent interface" in this manner does seem more conversational and thus makes code more readable. However,as I understand it from Fowler, fluency has more to do with code that reads like it was a business document describing its domain -- his thinking on domain specific language.
Hi, TSRh's method works and it's the best I've found so far. I've bloged(http://atpeaz.placidthoughts.com/index.php?/archives/153-Fixing-the-Windows-XP2003-Taskbar-Tooltip-bug.html) on how I used it with a shortcut key assigned to execute the fix. It's so good I've even mirrored the fix at the expense of my hosting bandwidth in case anyone wants it...
Well you can continue to use Yahoo Messenger (YM) using the GAIM Open Source client which support archiving and logging :-D
thanks william, i'll check it out...
That's very good! Put to my website as well.
I wonder if it's really good that they make an archived of your conversations online.
of course you can turn it off if the conversation is a private one
I believe Gaim still saves the logs locally. You could choose to save it as plain text or HTML though, which is more easy to manipulate than YM's binary archive.
Oh and yes I like using GTalk. I'm not a fan of it's non-standard interface but the Gmail-like grouping of windows is interesting. I do hope it gets a WinKey-Y equivalent to that of YM's, esp. for keyboard junkies.
wow, i didn't know about the winkey-y shortcut for YM

whatbis the combination for the safe
Ironic ano? In thinking that try-catching all will help him, he actually makes it more difficult to debug and refactor code.
Look at the kind of processing that the constructor does. I would bet many of these processes can be delegated to separate methods or properties.
However if the process really just does one big important thing, maybe just put it in a separate method and call the method from the constructor.
Single-responsibility principle applies to constructors too.
it depends.
if part of the design of the class is to have it ready in some state upon initialization then in my opinion it's perfectly valid to call some processing routine within the constructor. what i don't like though is a constructor that does everything within itself :P
too much reliance on the debug/console window leads to scroll-blindness in my opinion, if you're doing too much debugging/console logging, you're better off adopting TDD
ei, cruizer, i once paired with him to write a single unit test, after it passed, he commented, he does not feel right with the assertions, he wanted to see it to be sure, using console logging. di pa lang talaga nya ma-embrace unit testing.
the thing for me is, if it's initialization is very intensive, i'd rather delegate the construction of the said class from another (like a manager?). at least the constructor is lightweight and can be easily used by the test cases (and fast)
ah, so something like a builder pattern. you delegate the intricacies of the task of building an object to a separate class. in my opinion that's better and more testable :)
hi frank,
months have passed and we haven't had any conflicts with subversion such as yours, specifically the bug in merge (if there is any). locks are real pain and i agree now as confirmed with some of my friends. i guess the key to us is we're using CI, so i commit on an hourly basis to prevent these conflicts.
i think i can relate on the merge conflict and i believe it happens even in vss.
Tough luck. I too was involved in a project that does not in a project where the team members are "hostile" to agile practices. I wrote tests for my code and created a continuous integration server that only I use. Programmers are very territorial: programmers are not allowed to modify code that they do not own. More so on parts that they have already tested manually.
Things changed when, one by one, the team members slowly get assigned to other projects (or other companies). I have inherited the whole codebase, and with that the responsibility of making the application work.
Adding tests to a finished (but buggy) application is hard work. Especially when the business logic is embedded in the stored procedures. I have no choice but to generate rows of data for the stored procedures to process. That is not the fastest thing in the world. But by the time I'm finished with the project (which also happens to be my last day in the company), I've already written about half a thousand tests and it takes more than 5 hours to run them all.
So what is my point? Add at least one test a day. By the end of one week, your 31 tests have risen to 36, and you now have a few more places that can be safely refactored. Read Micheal Feather's book: Working Effectively with Legacy Code and go look for the chapters on refactoring code without tests.
Good luck!
half a thousand tests which runs in 5 hours! wow! you never told me that you also have a CI server on that company.
Aren't you just missing "Call" before "MsgBox", as it's a procedure?
i've seen the docs and it says it's optional

True, but I still don't get it why your company are hiring people experienced in TDD/CI combo devs while you know they are very few and you can hardly find .NET devs with such qualification. I only know two companies here. Why not just give others the oppurtunity to learn and be trained from it. Is agile companies promotes elitism?
i think it's not a hard requirement. i have experience with TDD but not CI. si build master calisay lang may experience dun, he he. then some of our new teammates don't practice them either. i guess it's just a big plus when it comes to the evaluation. di naman siguro elitism rodel :)
CSLA.NET -- master jokiz pag may time tayo gawa tayo ng MbUnit extension na pang-handle ng testing nito :) or meron na ba? :D
rodel:
elitism? nope. it's just a plus if you've worked in that kind of environment. too bad my boss did not know about the statistics of local .net devs (mas marami pa nga ata for java) on those xp practices.
besides, the boss does not even require us to practice tdd/ci. na-setup na kasi ng previous devs, and hopefully, hindi mamatay yung trend. it's us developers which encourage teammates too. in our current project, i was not that successful in encouraging my teammates, as a result of my previous posts
cruizer:
sure, pag may time, :p
nahihirapan tuloy ako dito sa current project ko, tightly-coupled ang classes sa data storage mechanism nya...hirap i-test :P
if it's tightly coupled, it's really hard to test in isolation, but you can always depend on integration tests
Maga-apply na ba ako kahit wala akong experience sa TDD, CI at CSLA? Hehehehehe. :p
he he teka, sino kaya sa amin ni jokiz ang makakakuha ng referral fee, ha ha :P
Yes it is: crap, spam, scam, etc - all the worse.

VB/A editor was very good a decade ago, but it still resembles the tech during those years:(as mentioned):
1.) No native support for the scrollwheel, add-ins were buggy. But you're keyboard mostly guy, who needs the freaking mouse when coding.(not designing forms)
2.) the CTRL+Y is a key binding from Word star
happy vba coding... :)
re: scrollwheel, i gotta do something when i'm thinking, hehehe... kidding. i still prefer mouse scroll when reading (codes/articles). gives me the continuous reading feeling, di yung, asan na bang line ako natapos last time.

>> tests for the correct data should be part of the client's testing
Yes this is correct. The client's (end users of your app/component) should be the one doing the initial checking for the inputs and output. Here at the bank we have sign off sheets. This is a proof that the data and info that our app is producing are correct.
This is sheet is signed both by the Heads/Users/Developers after a Parallel/Mac Test.
Or else if the developers will be the one cheking it. They'll be paying hours of hours using "DEVELOPERS RATE" for checking the inputs and outputs. =)
Pero Ganun talaga minsan ang users reklamo agad pag mali ang output pag chineck natin hehehhe inputs pala nila ang problem.

hi comgen,
i was referring to the "client" as the client application developed in .NET
I'm encountering this same issue. SelectedText seems to be set only *after* the SelectionChangeCommitted event is fired. This goes against the event documentation's own example...
hi jokiz, your experience here is another argument for the importance of testing stuff in isolation. in your case, an error in another module (the one generating the file) cascaded into your module. it's perfectly valid to expect, in your case, error handling on your excel workbook stuff if it's a user that will feed data to it. but since it's a machine, it is expected that it should be giving you correct data.
thanks for confirming that cruizer. as a result of this, tester often encounter breaking in my assertions or even invalid castings which are taking my time to debug on which was the cause. i think it will be better that i include a somewhat data cleansing utility or test that i could run on the newly written workbook, just to tell if client is behaving as expected. well, that's just to easily tell if it's the client app's fault.
Hehehehe mali nga ang kuha ko =P
Wahehehe. Welcome to my world bro. VBA development is no easy task if I may say.

We have been using NHibernate for most of our apps here in our company and having persistence tests for
i think this calls for having a database instance for integration testing that's separate from the actual database used for the application.
that way, a test can be configured to run a particular method that will populate the integration test database with initial data for the test run. then at the end of the test, the data can be wiped clean.
Hi Jokiz,
Good point. For the NHibernate Generator of our GenWise Studio product, we are also generating NUnit tests automatically. Currently they are non destructive, only testing correct mapping.
I think it would be a great feature that a tool like GenWise Studio can automatically generate all CRUD Nunit tests and can auto-generate test data. GenWise already has extensive information about the database schema and the resulting NHIbernate mapping. The issue you describe (object c depends on b, which depends on the existance of a) unfortunately makes the generation of these kind of tests much harder, but it would be extremely cool IMHO ;-)
I sort of encountered the same problem ago. Reloading the test data on every test is slow and would sway developers from actually writing them (as what is happening to our Struts Action tests).
I took note of how save() DAO tests (which modifies DB state) work in a blog post before. Not perfect, since developers should still be mindful in writing said tests.
http://blog.ealden.net/article/testing-dao-save-methods
I'm not that familiar with rollbacks but if it would provide a transparent way of isolating tests then that would be great.
yeah, thanks to Keith Rull for telling me about it (via his blog) too -- :)
Thanks for the props cruizer :)
Generics is great. Use if right and you'll have clean and maintanable code. Use it wrong and you'll be doomed with the curse of non-maintainability.
Yep, generics are great. Not only can you subclass them the way keithrull did, but you can add constraints so that your subclass only accepts objects of a specific type.
Great for the application above.
@cruizer-having a separate database is no need if i can just re-run the scripts before and after running the suite, it's a little complicated when data of each test cases is considered.
@ward-thanks, good luck with your product
@ealden-yep, similar views, rollbacks is just the same transaction envelope that you talked about
@jon - you can also add the same constraint with collectionbase in .net 1.x, through onvalidate, but there is a trivial hack for that
This might just be a fluke, but it seems I get the combobox to work correctly if I click the button portion of the control, but it does not fire the SelectionChangeCommited event if I click in the text portion of the control. The validated event seems to fire in either case.

the way i see it no matter how passionate a developer can be, or how good a company can be in terms of opprunities to get invoilved and experienced the trends and latest, at the end of the day, its all about money.
it just bad for companies who invested much from recruitment to re-training etc when in a very short term they will just leave and go. worst if a project contract was already signed and everything was laid out and ready to kickoff.
I have been to several situations like these but i think its still good to wait and see and but do my homework first and finish.
I understand sometimes we encounter offers that are just too good to be declined hehe but I would just say, its your call, good luck!
I believe that you are one of thre brightest guys in the local scene right now and i see you as somebody who is really worth the big bucks(and the distinction of being a great developer) ;) especially knowing that you have so much knowledge about technology... and that knowledge would really benefit any company that you go to.
God Bless Build Master Jokiz :) and I wish you all the dinero that you greatly deserve to come flowing in your pockets ;) :P
sometimes it is not just about money. sometimes it is about "perceived" opportunities. junior people tend to see things in terms of cash and perks. that is the reason why google was so good at recruiting. they did not pay high salaries in the bay area scale. the just gave a really cool work environment and stock options. both are tools of "perceived" opportunity especially when google didn't even make a single cent.
Misys Wow... Big Bucks here specially for RPG Programmers. Misys developed the system we breath here at the bank. but 2 of my team mates here came from Misys. =P My company offered a higher pay =)
@rodel - thanks!
@keith - salamat sa bola
@william - i've done that in my junior years, choosing other valuable opportunities over salaries. this time, i wanted to save more for the future. working abroad is very tempting
@comgen - ganun, ano bang company yan? they might have been just pirated for the application
In my very short experience in the business. The only thing I can say is that companies work for the sake of their own personal interest. Just like how countries would ally each other not for the benefit of the other, but for itself. So I don't see anything wrong with choosing the direction that is right for you and that you truly deserve.
Yaps your right sir Jokiz =)
@jokiz: lols, maybe we're not getting any younger. i must agree, retire young is a long term goal.
@keithrull: i must agree, probobly in the philippines .net arena, he's a master. so i wonder why he's still hesitant to take the bug bucks outside, hmmm....
@hip2b2: i must disagree with that sir :). i think its the seniors that perceived things more in terms on salaries and perks. stock options are only good for startups to make developers stay in the company at certain time or make seniors (spend x years in company) stay longer. offering stock options for a new senior employee, i think is not so appealing.
@comgen: i just know very little about Misys but only i can rememver in their .Net Programmer post, you are required to have knowledge in PC troubleshooting and maintenance of vb6 aps. no offense :)
oo nung wala pa akong pamilya, wala akong pakialam sa sweldo :P
jokiz pasensya na at hindi mo na makukuha yun referral fee :( nevertheless salamat, cormant is one of the best companies i've worked for, kahit na sandali lang
@rodel- re: misys and vb6. hey, i just knew vba, pwede na ba un? hehehe
@cruizer - re: referral, oks lang yun bossing, salamat din sa ideas.
bah, if you want to call a function or sub with parenthesis and not have to get a return value write:
Call MyFunction(bla, bloum)
it is the same as
MyFunction bla, bloum
but at least you have the parenthesis... I just hate the "Call" word... it puts blue everywhere and makes the code quite confusing sometimes, but I prefer it to calling functions or subs without parentesis.
As someone mentioned, this "call" is not needed anymore in .NET... what a relief...
(like the "Set" for the objects... given that everything is an object, even the in-built types, I found that illogical too...)
Have fun!
@jokiz: this is true bro. i think alot of guys lookup to you. just look at your feedburner subscriptions :P and your google hits. you are a smart guy and alot of the guys here can attest to that.. and heck! you can use us as your technical reference ;)
@hip2b2: i think its the potential of the company that got those people to stick with the company. just look at some of the startups today.. i know several people who stay with their startup employers because they believe that greener pasteurs are ahead of them if the company goes up to where they believ it should be. plus.. nowadays its the bills you pay that rules your decision.. although i know that in my current situation its my happiness with the work that i am doing thats keeping me with the same company(even thou i got several offers.. its the comfortability that made me stay).
Langya kayo, ipipirata niyo ako tapos iiwan niyo ko?!

Cruizer and I have together seen some of the worst possible scenarios an IT company can face, and if he says that Cormant is good, I would believe him -- we've had enough sh*t already.
Likewise, because I already have a family (not as big as cruizer's though :p ) going abroad is something that I'm actually trying to avoid.
And because my resume is already *too* colorful, I'm actually looking for a company to settle with for, oh, at least the next 2 years. :p

hi jim,
if there was no change, i believe selectionchangecommitted does not fire, i have to check it out again.
i once joined a team in developing a procurement/bidding system in ASP.NET. it involved "project for
Master Jokiz, I have not tried this but i think adding a trigger for the table is another option
some other alternatives I've used for this:
1) generate a GUID for the ContractorId (easy way out :P)
2) normalize the ContractorId into another table where it will be the incremental Id
My first option would be to use a dates (if necessary, datetime) instead of version IDs.
When contractors change, I log the date on when the change will be effective.
When looking for the contractor profile for a project, then I'll just use the a projects start date/bid date an look for the contractor "version" that was effective during that date.
Read Temporal Objects from Martin Fowler's website (http://www.martinfowler.com/eaaDev/TemporalObject.html) for an object oriented solution for your problem.
In your scenario, a Contractor will be a temporal object. Projects can have many bidding contractors. The relationship is contained in another object, say ProjectBid, which knows a project a contractor and the date the contractor joined the project.
As amil pointed out, you could've just used sequential GUIDs. Some other ID/PK should then be used to indicate the linked profiles. Use the GUID to link that specific profile instance to the bid.

yeah but sometimes you get people who know what they are but don't know how to apply them in real-world problems. or you can turn away those who work great in solving real-world problems but don't know everything you're asking (yun mga "just in time" learners, in contrast sa mga "just in case" learners; see Kathy Sierra's blog entry: http://headrush.typepad.com/creating_passionate_users/2005/03/motivated_to_le.html)
we're both on the same side boss, exactly what this post is about. thanks for the link boss, reminds me of what i teach my students in high school, learn not to memorize the mathematical formulas but how it was derived, and why it works so they have a deeper understanding of the type of problem
naging teacher ka pala jokiz?!
not actually, i had few students lang (3-6) for my math summer classes

for me integration tests help me flesh out a good API for my classes and contribute to ensuring SRP. but in my experience, doing mock testing did not help ensure i have a bug-free app. nowadays i think "testing" is a misnomer. i tend to agree now with the BDD people who say that tests should be called specs and that BDD/TDD is a design process, not a testing process :)
Previously jokiz bloged about this one , I'd like to add further. The same issue cropped up again in
we called it "Divide and Conquer" Algorithm
Thats interesting...! Another possibility is a mismatch between 32 bit and 64 bit binary for operating system.
Thank You
Thanks for the information. I was just looking for where to put the XML documentation when the DLLs are on the GAC.
Just a hint, invalid comments are worse that no comments. It's better to not generate docs if they're not updated that to have invalid information.
If you keep the old documentation you never know when you can thrust on what Intellisense sais.
Just my 5 cents.
Thanks again.
Hi!
Im doing a aplication to smart device.. and we don´t have selectionchangecommitted.. what to do in this case?
yep, but it's very common for the xml documentation to be not synchonized with the code, i've seen it 90% of the time
i guess you have to take selectionindexchanged and work around it, don't forget the DesignMode checks for windows forms, it would help sometimes
I agree with Frank, svn sucks! We were forced by the team manager to use it and we all (a 10+ people team) miss the good old vss times. The edit merge model is not for us. My main complain is you don't get any warning when modifiying files that other persons are modifying at the same time. At least you should have given the option to wait. Then you go througt the tedious colnflic solving process. awful
I know this could be kind of late, but I believe I have found an elegant solution to mocking dependencies to Csla objects using TypeMock library: please check my post at:

I feel the same way about passing the IDs around. Those tie IDs are specific to the database and tie you to the database. You should just be passing around business objects... but it doesn't look like that's a common practice in ASP.NET
great finding jokiz :) certainly unicode should only be used if the non-ASCII characters appeal to you or is absolutely needed/expected for the app
thanks to boss, he's the geek who observed about it
Yes, prefer to use Unicode at all times. It is more space, but when you get to size that you really are concerned about it, you almost always needs unicode
NHibernate v1.2.0 Released - A impressive production-ready release from the NHibernate team. If it was...
wow sarap! sayang di ko inabot... :)
alin boss? inabot mo yung project na un ahhh
i mean yun books.
seriously yun project na yun was one of the most enjoyable i've had, thanks to TDD and CI :) namimiss ko na yun dito...hindi CI dito, at hindi rin TDD (here, "unit testing" means you test the code yourself, ha ha)
awww, ang slow ko grabeh... i agree, once you've worked in a tdd-ci environment, you wouldn't turn your back and do it the old way again (given the chances, meaning if you're not working in a bank, hehehe)
Well I guess the real problem would lie on defining what "sufficient" code coverage is. There was this post on object mentor (blog.objectmentor.com/.../100-code-coverage)that said that "if your goal is 100% coverage, you’ll focus on that goal and not focus on writing the best tests for the behavior of your code."
So the challenge would be to strike a balance between teaching the *value* of TDD and code coverage, as well as writing good tests, so that the objective is not 100% code coverage, but instead, something like 80% code coverage but *with very good tests*
Ako pala yung nagsabi ng best "legacy code" :P
As I explained, maybe the difference is in how I define legacy code. My definition goes like:
a) Code that was made by me more than 6 months ago (yes, that fast). Sometimes even code made by me more than a week ago because I easily forget things! :p
b) Code that was made by others, no matter how new.
The operative concept being intent: once you forget or don't know or understand or is confused by the intent of the code, it's legacy code.
However I would agree that, because the tests document the intent of the existing code, code that is covered by *good* tests can't really be considered legacy.
good point. i intentionally didn't define what is sufficient code coverage for me since i really don't know what is should be.
i've read that object mentor post before and i agree with his point.
however, i know most of our developers are not really into writing automated tests and the way i see it, forcing them to write tests would mean keeping a 100% code coverage. not so good tests are acceptable at first since we are still learning but we'll know about them not being good as we go along the way.
personally, i still have some quandaries on the ideal way to test things, setting up tests, etc. and i still don't have anyone to tell and share these stories with, are you in? :p
At the risk of sounding draconian, you could insist that no code be committed to the code base unless accompanied by the appropriate test cases. To make this more manageable, you could enforce this policy on the newer developers only.
hi robert, incorporating code coverage rule in our continuous integration setup is better than having just a policy since breaking this rule will break the build, :p.
OT: mobius company? you from downstairs, there's a mobius company in our building at net one, taguig
If the new developers still do not understand the value of TDD, then the only thing you can do is seduce them to the test driven way of programming :D. Most of the times, though, they are the ones that produce the most bugs. When defects arise, take advantage of the situation and let the team think of the tests that would have uncovered that bug if only the code was test driven. It is not directly helping to the "code coverage" metric but it doesn't matter. What matters is that the team learned something out of the bug. Hopefully, the guy that introduced the bug learned something, too.
There are also those developers that are test driven already but are tempted to go back their old ways because they think they've hit a hard to test code. When that happens, then you can just all agree to call up a meeting and brainstorm on the ways to test it. I think when you start doing this, you'll get meetings every few minutes. But as you go along and gain a lot of experience writing tests, the meetings should eventually dwindle. This idea came from Michael Feathers (I think) but I am unable to find a link.
Not sure if I'm qualified. I myself am not putting up as much tests as I should, nor am I putting up tests firsts the way I should. :p
These things are what you miss cruizer for.
I have a new post in my blog (dotnet.kapenilattex.com) that somewhat answers some aspects of your quandaries. Hope it helps :)
@jop, i'd love to have those kind of meetings.
the idea on pointing out the recurring bugs to the one who does not write tests sounds familiar, i've done that with some of my officemates. it's really better for them to learn that way.
but the worse scenario (which really happens) is when some of them leave and you're stuck there afraid to incorporate a feature in their module without breaking their existing implementation without tests.
Yipes, I should've read your post more carefully before talking out of the proverbial you-know-what. Yes, including coverage in the build success criteria is better than a policy (we live in PHP land where unit testing/coverage tools aren't quite up to snuff).
Do you personally insist on 100% coverage with the code you write? If so, (and I have a feeling you do =), then apply that standard and expect the same from your group, they will be better off for it.
OT: Yup, 8th floor. Pay us a visit anytime. =)
# jokiz
I understand your situation. Someone leaves and their knowledge about the module is not encoded in test form. The leaver will be asked to create a handover "braindump" document detailing whatever it is that is needed to be explained to the pitiful guy that will takeover the application.
I think there is a better way. Rather than ask the leaver to create the document, I think it is much better to just take over the application on the very day that he filed his resignation and try to work on the application. Start adding tests and refactoring, while the person is still there and you can still ask questions. Look for the biggest files, biggest, classes, longest methods, most complicated code, and work from there. Read Micheal Feathers' book and then memorize Resharper's short-cut keys. You'll be using it a lot. :D
thanks for the heads up jokiz! the RowTestFixture is really cool. and so is the EmbeddedResource feature, since I'm embedding test documents.
can you send to me about that. I mean about keyboard shortcut for word 2002 and 2003?. thanks a lot.
just click the link for the ms kb
resharper's short cut keys? hello, nasa dugo na rin yan! well in our company, turn over happens in just one day sad to say. btw, i'm currently browsing feather's book, thanks!
Jetbrains has just released their beta version of Resharper 3.0, download it here . Again, VB.NET guys
I had 2.5 installed and installed 3.0 Beta over it. It broke my intellisense :( I can't get visual studio or resharper intellisense working now. Really disappointed. Oh well, back to 2.5.
Yea I'm experiencing some of the same problems. For the double resharper menu, You have uninstall all resharper versions and then run dev.exe /setup from a command. then install resharper 3.0... Of course that will reset any custom visual studio hotkeys you have set up.
tony, the workaround proposed by jetbrains i think is better for the double resharper menu
I think this is a very good tool to look up to(for me) in the future. :)
Thank you. I also have lost half of my working day to fix this small but really annoying issue.

Yes. The INI files.
We need this methods to support current applications.

The ConfigurationSettings class operates with the XML files. It's fine for applications... without backward compatibility.
This has worked to me.
Thank you so much!!! I was getting really mad when SelectedIndexChanged was firing multiple times. Thanks again!
Use ExecteScalar. ExecuteScalar is used when you just want one single value from one single row, as in:
SELECT Name FROM Users WHERE UniqueId = 42
ExecuteNonQuery is used for SQL statements that don't return any data (For example, INSERT, UPDATE, DELETE)
or...don't attempt to fix it if you don't have regression tests at hand ;)
O bushing, what gives?
Define "broken"?

thanks jokiz, your turn next year :) i think glenn moved his blog to phissug.org, that's why his devpinoy blog hasn't seen action lately...
nyek, di naman ako kasing active ninyo. anyways, para alam nila na star studded bloggers dito, hehehe.
re: glenn's blog, onga noh (phissug.org/.../default.aspx). so he's an ex-devpinoy blogger now, sana aggregated na lang dito if possible with community server

uy tnx jokiz! nde ako ex devpinoy blogger uy ... hinahanap ko kase yang aggregator na yan hehe. I really need to get things going din kase with phissug. was forced to blog there some months back kase nde na gumagalaw yung site. at least lately medyo gumagalaw na kahit papano. yung sql related blogs ko lang naman nalipat ng phissug. yung iba sa devpinoy pa rin. though wala ako mablog lately na nde related sa sql heheh.
pano ba gagawin para makita rin sa devpinoy yung blog ko from phissug?
sorry bout that master glenn. i have no idea but i believe it is possible, a lot of bloggers are doing that with community server. you should consult keith about this
Why are all the good people leaving the country!!! Though as you said, there's a possibility that you're not moving there. :)

SVN is something much, much worse.
I am at a client site where they recently made the switch from VSS to SVN due to a source safe database crash (so I'm not promoting VSS here). But the switch to SVN (using both TortoiseSVN and ANKHSvn) has been the proverbial jump from the frying pan into the fire. I have spent more time in the last month fighting conflicts, merges, lost files etc then I have in my prior ten years as a developer. Developers cringe when they have to commit their changes (so they dont' do it as often, not a good thing) at what they will probably face trying to resolve conflicts. The standard now before committing changes is to make a local backup of all of your source code beforehand due to issues with files coming up missing. I didn't think it was possible to both Suck and Blow at the same time, but I have since been proven wrong.
I am on a team with only three developers. I shudder to think of what trying to develop on a larger them with this POS must be like.
Save yourself a lot of time and grief. If you are switching from VSS, looking at Team Foundation Server or SourceForge Vault (I'm sure there are others as well, but these are the only ones I'm familiar with). I wouldn't voluntarily use Subversion again if I was paid $100 every time I modified a file. (well I might at that price, but I'd have to think about it ;)
If I can just save one person from going through my pain, I can rest easy when I die knowing I have eased the suffering of another...
Hello , I wnt to get the files in alphbetical order using c#.what should i do? thanks in advance
if you're using FAT, you have to sort it manually
oh no! so what's the solution then? program the class to catch the offending string (PRN) and replace it with another, harmless (to Windows) one?
Object name yan na PRN? Diba string lang naman yung gateway code...
yes, and PRN is the directory name that's being created, which will fail.
just prepend (tama ba word) the codes with underscore so no special handling for the keywords.
Posted a problem and commented a right answer. Unless when they come up with a reserved names with an underscore, probably in 10 years or never.
# deadline driven development Ah, DDD, short for deadline driven development. At least you are not doing the other kind of DDD - document driven development. Btw, I need an MS Word plugin - if you know of a plugin that can syntax-highlight code and has intellisense - all inside the pristine confines of MS Word then I'll pay big bucks for it. :)
what for?
How much big bucks are we talking about here? ;-)
bastusan ba raw, cge pagbigyan ang mga bossing
ha ha. jokiz i saw that "new search engine using deadline-driven methodology" comment before my last day in the company :P
personal observation though: using TDD didn't assure me of bug-free code. in fact some of the bugs that were reported during QA and UAT were because of my code :P but the tests helped me isolate the bugs and fix them. also doing TDD helped me come up with an API/interface that (I think) is usable.
that reinforces my belief that TDD is not about testing but designing software based on expected/desired behaviour.
What a rant... it seems that you’ll going to reach your boiling point. “Deadline-driven development” Sacrificing the value of TDD. "Senior guy is giving junior guy latest copy of his bits every morning." >> Why? They don’t like using repository? Oh oh.. "From ASP.NET to ASP classic" >> this is funny. Why use ASP classic (I hate to see those inline codes.) when you can do it in ASP.NET with no pain.
# jokiz - what for
Hehehe.. I've been doing a lot of coding in MSWord lately. We are required to get the documentation reviewed before starting coding.
# velocity - big bucks
two adult male antelopes :D
# cruizer - tdd
Now that you mentioned it, I should probably write an xUnit tool for MSWord. WUnit?
@cruizer very well said.
@cruizer: agree that it doesn't assure bug free. disagree on tdd is not about testing but designing classes.
tdd makes it possible for classes to be designed as testable, but in the end, all you wanted is to include automated tests EASILY. these tests are the one helping you in the long run
automated tests are there to easily know if you've broken something, we all know how helpful it is. if it's wrongly written, it will be discovered and should corrected.
# cruizer - using TDD didn't assure me of bug-free code Yes it does assure me of bug-free code, BUT only on the code that is covered with test. # jokiz - disagree on tdd is not about testing but designing classes. TDD is about design - it forces you to think cohesion and coupling. It is also about requirements - you put your specs in the code, and you make it pass. BUT it doesn't stop there. Once your done with the test, then it moves on to its other role: as test.
@jop, yep, agree that it is about design with a higher intention of "to test". just disagreed on cruizer's comment "tdd is not about testing"
well "TDD is not simply about testing" -- part of it, but not everything. i guess the reason why others shy away from TDD is because they think it's a replacement for actual testing, which it's not.
using TDD on the stuff you mentioned help me adapt the API quickly in the face of refactoring and changes. I probably wouldn't have pulled it off in a more efficient manner if not for the test harness (automated alright). It also helped me isolate class responsibilities.
@cruizer - that's better than your first statement "TDD is not about testing". :p.
by golly yeah :D but to me the value of TDD is in allowing me to freely refactor code with wild abandon, knowing that the safety net of regression tests are there to keep me in check. thus I can easily evolve my classes and methods and see immediately that everything is still working as expected. so really it's more of a design tool to me ;)
Hehehe... Guilty as charged! (raises both hands and both feet)
Send me to the TDD slammer now ;)
When you're working with a non-TDD versed team (as we are at this point) someone has to somehow enforce it, usually the lead. But since no one is TDD-esque in the team anymore, including the lead, nobody's enforcing it, really, and many of the members treat the tests as obstacles rather than as tools.
Oh yeah... for #2: I eventually told the senior guy to ditch his CSV parser hand-coding and get a library. I'm not sure if he downloaded the same thing the junior guy was using. But it eventually saved him from all that trouble.
Seems to me senior guy has an NIH attitude that needs to be, ummm, regulated. :p
Pingback from DotNET @ Kape Ni LaTtEX » Blog Archive » The TDD wake-up call
BDD is the course-correction needed for TDD. It's the same banana but peeled differently.
http://behaviour-driven.org/
Have you tried taking a look at WiX as an alternative to building setup/installer projects.
http://wix.sourceforge.net/
There's even a project(early in dev) to tie up MSBuild and WiX together.
http://www.codeplex.com/WiXML
even in the release version of 3.0, I found it painfully slow on vb.net.
Well i guess second guessing comes natural when all the facts are not available, but uninformed condemnation is wicked. First off, has it occured to anybody that maybe those DDD comments were a (witty) expression of utter frustration to of how the current code goes against everything this senior guy expected how the this project would be ran (in all its promised test driven-ness, sacred object orientation, and Agile-ness). When youre required by your manager to put in more than 10 hours or work everyday, to work on Saturdays and Sundays, (and, yes neglect your email and daily news browsing) just so you can hit what the upper people promised to deliver on a date that was set even before the senior guy started work with the company. When somebody goes by your desk to ask if how come you havent finished fixing 10 bugs, after all it has been 1 hour since the last time he asked you. It surely doesnt sound TDD to me and i wont call it by any other name. Here's a trivial exchange from that project: 1. mgr asked sr developer to fix n bugs of a system he just inherited. 2. sr guy says it'll take a month just to modify the code, 3. mgr ask to render all waking hours as overtimes to finish it in a week, 4. sr. dev asked about time for the unit testing, 5. mgr says skip it. And oh, by the way, did i mentioned this company promised the sr guy that they never do overtimes. The csv incident. Who made the sr guy the team lead?!? because i assure you the sr guy doesnt know it. The team lead is the guy who holds weekly meetings but everybody seems to be afraid of talking with (cept the sr guy of course). If one does a quick hack of csv-to-database persistence by using the quickest means possible, he wouldnt bother looking for the perfect tool. And surely he wont put it up under version control since its still not ready. And if a jr guy asks everyday for something to do to help but doesnt have an idea how, would the sr guy keep the source code to himself? By the way, has anybody seen the csv importation code lately? The one that actually made it to svn. Does it contain a single call to a Split() method? I always wondered why you decided to work on csv imports/display when we were assigned to do separate tasks. It cost time by you not working on your module and us doing redundant work that has to be integrated. and... and.. it went against the skills training of the jr guy by you thinking it througg for him. The ASP.net/ASP classic argument. As has been repeatedly mentioned by the team lead who holds weekly meetings, the whole point to the project is to get clients interested in what the system has to offer. Up to this point its still classified as inhouse and, hence, is paid for by the company as an expense (as opposed to being an income). The object is to demo it as soon as possible using (ASP.NET, ASP classic, perl, sql, or whatever.) The senior guy doesnt care, as long as it worked. The irony is the ASP.net version somehow got checked in with compile error. I dont think tdd is the only way to test code, but at least one should code the code before it is checked in. As to ASP.net vs ASP classic, thats another story worth another thread. Whew, nothing like a long rant against a long rant... Nice blog site. Best regards,
@the senior guy
am sorry to hear about your bad experiences with the project.
"If one does a quick hack of csv-to-database persistence by using the quickest means possible, he wouldnt bother looking for the perfect tool. And surely he wont put it up under version control since its still not ready." - i disagree, if it is a team development (2 counts as a team), it should be in version control even if the code is not yet ready or not using the perfect tool. besides, it's free!
"By the way, has anybody seen the csv importation code lately? The one that actually made it to svn. Does it contain a single call to a Split() method?" - yes, the point is the time wasted when you two are doing the same thing differently which you both have no idea at that time.
"I always wondered why you decided to work on csv imports/display when we were assigned to do separate tasks. It cost time by you not working on your module" - i did not work on any import, i said i saw both of your codes as you both asked me for some help at your desks so the rant was just my observation.
"it went against the skills training of the jr guy by you thinking it througg for him." - i just led him to do it in the correct way to do it because he was asking me how to do things properly.
"The irony is the ASP.net version somehow got checked in with compile error. I dont think tdd is the only way to test code, but at least one should compile the code before it is checked in" - this is my fault, i did not setup our CI server early on because there was none available. besides you also had problems checking in code which does not compile on our machines. this should have been captured by the ci server which i set up before i left.
thanks for commenting!
Errata: <br>
By "code your code..." i mean "compile your code..."
As a personal preference i dont check-in test code. Just because its free doesnt mean it doesnt come with a cost. Ive not yet even finalized the file names. To check it in would mean a lot of rework for me later on. Anyway its a personal judgement just as you have your own. Time is only wasted when the jr guy or the sr guy didnt learn anything about what theyre doing. Theres nothing wrong with doing things differently. It's an exploratory period, its natural to test things out. And besides, the task is simple enough for one person to do. The team lead assigned the jr guy to me not so much for help but for training. If the jr guy is made to do redundant tasks, its not w/o a reason. Youre right, i too am guilty of checking-in code that broke a build (which i do quite often if i may say), but i fix it the moment i find out about it. And its mostly because of new files i forgot to check in. The asp.net code stayed broken for more than a week until i had to replace it because we needed to do a demo. Anyway, on a personal note, i have a lot of respect for you as a fellow senior developer and a work mate. If theres something sour about this whole thing is that the rants useem to have unfairly (wittingly or unwittingly) made a bad person out of me. You will probably not know the things i did just to make that project a better one. For one i was probably the first person to inform the team lead how bad the existing design was. Thats why we had a reenginering project in the first place. I always (and still does) welcome your feedbacks just as i direct them to you personally about things i dont like about the code or the design. By the way, how do you format these blog text into paragraphs anyway?
"Ive not yet even finalized the file names. To check it in would mean a lot of rework for me later on. Anyway its a personal judgement just as you have your own." - i respect your view on this, but note that subversion stores history of files even when you renamed it, :p.
"Time is only wasted when the jr guy or the sr guy didnt learn anything about what theyre doing. Theres nothing wrong with doing things differently. It's an exploratory period, its natural to test things out. And besides, the task is simple enough for one person to do. The team lead assigned the jr guy to me not so much for help but for training. If the jr guy is made to do redundant tasks, its not w/o a reason." - point taken on your explorations on csv parsing. same reason why i was surprised when jr guy was doing it in asp classic, so i introduced him on how to do it using repeaters and gridview, to train him.
"Youre right, i too am guilty of checking-in code that broke a build (which i do quite often if i may say), but i fix it the moment i find out about it. And its mostly because of new files i forgot to check in." - you know why? because you disabled AnkhSVN which should be the one to automatically add the files to subversion when you add new files to the project. i was surprised why the jr guy has ankhsvn disabled too and i found out you advised him to.
"The asp.net code stayed broken for more than a week until i had to replace it because we needed to do a demo." - i'm not aware of this, you should have confronted the jr guy who did it since he was ranting to me that you replaced his code with the asp classic style.
"If theres something sour about this whole thing is that the rants u seem to have unfairly (wittingly or unwittingly) made a bad person out of me" - sorry about this but this post was to share my reader my experiences with work and at the same time raise argument with them for a discussion if ever there are some points that i view differently from theirs. this is not meant for officemates or bosses to read, :p.
"I always (and still does) welcome your feedbacks just as i direct them to you personally about things i dont like about the code or the design." - I also did direct to you both items that apply to you (2 and 3). #2 i asked you why not use subversion, #3 i asked you why do it in asp classic way, i even asked you to choose between classic or the asp.net way for our implementation.
"By the way, how do you format these blog text into paragraphs anyway?" - double line breaks will do (html disabled, drop your <br/>'s)
@Jon Limjap.. on NIH First: Split() is not what i can claim as my own csv parser; Second: im the one who told you about how cool the csv parser tool i found on the net that treated csv files as stream object. i was looking for csv parsers even before i told you about it. Third: I have an old habit of understanding what my needs are before i go forth and look for a tool. I have been burned countless times by 3rd party tools not delivering on what theyve promised. Nothing's wrong with using a 3rd party library/tool just as long as you know why youre using it. The sin is when one continously use them when theyre no longer needed. Fourth: I hope time will never come when one should have to regulate intellectual curiousity and creativeness.
Just to let both of you know, I also disable my AnkhSVN because it hangs my VS, but I have little or no problems with doing manual adds in Subversion because I made it a habit to diff the files that I'm going to commit.
I usually do this to check if I'm committing any "test aka trying-it-out" code, or commented code (everyone knows how I hate those). So I see which files haven't been added yet. It doesn't take too much time because I commit few files at a time often -- at least most of the time.
Maybe that could help
Senior guy,
Point taken -- however, most of the time you have to be realistic, take a step back, and think: hasn't someone else solved this problem before? Someone must have addressed this and posted their solution somewhere.
I'm not saying that we should rely on 3rd party solutions all the time, but we could take time to check some of them out (especially the open source ones), see if they fit our needs, see if they work, get rid of them if they don't. Especially if the problem is something like CSV parsing, complete with all its caveats.
And I do remember telling you to "not reinvent the wheel"... I'm now not sure which came first, the 3rd party tools or me telling you that :P
It's nice to explore our intellectual curiosity and creativity, but there's also the need to be pragmatic and prudent, especially when you're on a deadline :p And I think I've heard the boss tell you once to not treat everything as an academic exercise.
I hope you don't misconstrue our intentions here: we're merely sharing what we think is the best for all of us devs. That includes you. ;)
@Jon Limjap
There's a difference between understanding the problem and reinventing the wheel. I used a fine and existing csvReader wheel. Is that a snipe at the customized expression evaluation we've been using? :P
I think satisfying our intellectual curiosity and expressing our creativity is not merely nice, but an intrinsic need. Why else would jokiz ponder upon the number 29 in generating hash codes. or why would I write a number-to-words script using SQL, or why would anyone try to fix a working code.
The Boss asked the *whole group* not to "treat everything as an academic exercise" in reference to the OOP class (which I refrained from attending) and as a reminder that the Project is a real application that's going to be used by real clients.
Is there any other way anyone can misconstrue a rant? Its alright, everybody's entitled to one. Thing is, I probably have more to rant about than any of you but I do my ranting on weekly meetings and group emails (and yeah, even source code comments!) where we can actually do something about them. Painting a bad picture of some dev however anonymous with half informed statements is hardly sharing what is best for us (which excludes the target dev).
(sorry jokiz, just one last shot..)
Training is one thing, spoon feeding is another. I dont believe in "training" somebody by spending a large part of the day sitting down with him showing the one "correct" way. And please, let's avoid speaking about correctness as if its something absolute. Id rather encourage someone how to think (inside and outside of the box) and make sound and independent decisions. They may not always be decisions I can agree with, but its better than parroting.
I know exactly why I dont use AnkhSVN. And its not because somebody told me so.
ahh, if you're talking about those moments where we paired using test-driven development, it's training in my vocabulary, besides, i let him drive the keyboard (no mouse, :p) 80% of those times.
Junior Guy (or is it Junior Menace), if you are reading this, you are also free to butt in. I'm also eager to know what's on your mind, or, judging from the comments made by your collegues, what's not (yet) in it. :D

Congrats! Welcome to kamote coding! nyahahaha!
thanks guys, ouch @ melvin
bakit kamote coding <offended />
ha ha :P
@melvin hahahaha baket nga ba kamote coding bossing? :D
Thanks. Nick your program worked a treat. TSRh's link led me to some russian page.
I just visited your site, just want to say goodluck to your new job! :D
nice tips. VS Team should enable this by default.
nice tip ;) kanina lang i was cursing VS 2005 for making it confusing for me to edit two similarly-named .cs files in two separate projects/namespaces. pwede naman pala i highlight. great! :)
nyahaha, see? may nagbenefit pa, hehe
VS Team should enable that by default. nice tip...
good thing it's enabled by default in VS2008 Orcas..
i don't like clearcase either...i miss subversion ;) although i think the company chose clearcase because it's backed by IBM/Rational and its strength is in branching
Automated merges never made sense to me to begin with but with SVN there have been conflicts 90% of the time where SVN has attempted to merge local changes during a checkout.
The whole idea of an auto-merge is counter intuitive. Suppose developers A and B are working on file 1. Both A and B go through their unit testing and A checks the file in and B merges those changes back into their working copy. Doesn't this mean that B should really re-unit test since they really do have a new code file?
Also we have a development team of 20 and we have mandated a lock-modify-unlock process in our production pipeline and we have NEVER had anyone sitting there twiddling their thumbs with nothing to do because someone else has a file they need. We simply have them work on something else until the file they need is is available.
Good one...... thank you so much
Under Visual Studio 2005 .NET, to get IntelliSense to work again if Resharper broke it, you can go into the \Common7\IDE\ directory and run "devenv.exe /ResetSettings" to reset VS back to defaults. If you have a lot of custom settings, maybe you can look at a way to backup the important ones, but this made IntelliSense usable again.
There may be a more direct way to solve the problem without resetting everything, but I've never tried Resharper and haven't had this problem myself, so you're on your own.
This worked perfectly...it solved a problem I had struggled with for an entire day, namely SelectedIndexChanged firing multiple times. I appreciate you insight and expertise!
I read Wes's excperience with incredulity...
Anyone losing code when committing to svn really needs to rtfm - see svnbook.red-bean.com/.../svn.tour.cycle.html
Doesn't anyone spot all those files with .mine extensions appearing in their working folders?!!!
See also svnbook.red-bean.com/.../svn.basic.vsn-models.html
for a good discussion of lock-modify-unlock vs. copy-modify-merge.
LEFT JOIN = LEFT OUTER JOIN
RIGHT JOIN = RIGHT OUTER JOIN
For point 2: FROM Table1, Table2
This is a syntax defined in SQL 92. Oracle people are used to this form.
It can be an inner join or an outer join depending on the where clause. For example, you can have this:
FROM Table1 T1, Table2 T2
Where T1.KeyID = T2.KeyID
@chomsky - my teammate also told me that, smart engine. but i do not know if it really tries either of the two joins? i need to verify it myself, ;p.
I am finding it harder and harder to explain how to round off numbers to my daughter who is in the 3rd grade, she just doesn't understand, do you have a simple way to explain to her?
Hi jokiz,
Nice little tip.
Thank you.
I like to be in control. I map Ctrl-9 to View.TrackActivityinSolutionExplorer and press the keys when I need to find out where I am in the Solution Explorer.
would have been simpler to use this.
isnull(au_fname, '') = isnull(@firstname, '')
in your 1st example. i'm confused???? if it is a 0.5 you round down or up. because the 1st example has no continuity. please help/advise????????????
thank you
With the merge model, you should always do an "svn status -u" to see if someone else already made changes before you commit. If there are changes already there, you can do an "svn diff" with various options to see what they are. If you don't go through a process like this before you commit, you will indeed have headaches!
Another thing, there are known issues with AnkhSVN not doing a rename properly. I wouldn't judge SVN based on a freeware graphical interface to it. At its core, it is a command-line program, and that is how I have used it for 18 months. I think it is great! It is reliable, secure, and fast. But again, people using this tool need to use it correctly by following an orderly process.
Currently, we are considering using it not only in our Unix environment, but also on our Windows/.NET platform in place of VSS. I am checking out various integration options for use with VS2005. I personally would avoid AnkhSVN until it improves. Right now, it seems to be giving SVN a bad name...
Guy
Thank you very much This information is very useful to us. We have spend 2days for solve this issue using SelectionIndexChanged. But after seeing this information we changed that to SelectionChangeCommitted It is working fine now.
once again thank you
I am experiencing the same thing. This is really annoying, but i know of a way to "kinda" get around it. If you go a head and write all of your code for the nested switch statements, and then manually tab the first case statement of the nested switch, and then select all of the lines below that and click edit->advanced->format selection it will correct the unusual indention. I wish there was another way around this silly, overlooked error.
It seems Microsoft is aware of the issue and refuses to fix it. See the link: connect.microsoft.com/.../ViewFeedback.aspx
really, is it 20,000 now. i remember u need to send a text message and show them the confirmation before you're able to get your rewards. do they still do this...?
how did you inquire about the new rewards program? they should give us a new phone instead..
Great tip Jokiz, I've noticed this issue a while back but didn't pay attention to it to much but just found this link and it worked like a charm.
Hi,
I have been facing problem because SelectionIndexChanged firing multiple times. I am using now SelectionChangeCommitted event.
It solves my problem but now when I try to select any item in my combo for the first time, it selects first item only and it works properly when I select any item next time.
FYI, I am using this combobox in my datagrid.
Looking for help!
Thanks a lot,
Prerak
Thanx for the aclaration, it helps me a lot.

By default, word automatically repaginates, esp. when you're in page layout mode.
View your doc in normal mode or turn off automatic repagination.
Assuming you're on Word 2003, go to Tools->Options->General and clear the background repagination checkbox.
