Free .Net Obfuscator

2008-04-09T06:24:32Z

I've stumbled upon a free .Net obfuscator --Eazfuscator.NET. So far, it works well for my purposes. Most obfuscators are costly--ranging from $200 to $2000! But this one is freeware and it works better than the free one bundled with Visual Studio 2005. It is free and easy to use!...(read more)

Printing PDF Using WebBrowser Control in .Net 2.0

2008-04-08T13:18:46Z

Okay, after almost a year and an offshore assignment, I finally had a chance to update this blog. I was developing a .Net 2.0 C# windows application wherein I basically have to print PDF files from a Windows application. I tried to use the Adobe Acrobat Reader ActiveX object embedded in my form to preview and print PDF documents. It worked fine; I just have to import the COM component and Visual Studio will do most of the Interop work for me. I then have to locate the file and load it to the AxAcroPDF...(read more)

WCF

2007-07-27T14:23:19Z

This week I had a Windows Communications Foundation training from Developmentor , sponsored by our company. I learned a lot about the new framework (dotnet 3.0) and communications. What interested me the most was the Day 4 topic which was Peer-to-peer applications. Although I might not be able to use it for regular business applications, I would be using it just for fun. Here is our instructor's (Scott Reed) del.icio.us link: http://del.icio.us/mscottreed...(read more)

Re: Do JavaScript after window.close()

2007-02-06T08:22:01Z

There is a slight modification for my previous post . The conditions for the if statement there is inadequate. The bug occurs when refreshing the browser when the mouse is beyond the leftmost side of the window, a valid yet unanticipated negative value for the X. This is evident especially for dual monitors--like what I am using. Thus the new conditions are as follow: if (window. event .clientX 0 && window. event .clientY 0 && (window. event .clientX -1000 || window. event .clientY...(read more)

Re: JavaScript Hashtable Implementation

2007-02-06T08:03:52Z

This is in response to my previous post re JavaScript Hashtable Implementation . I modified my code to be able to remove elements, as well as get an enumeration of the elements in cases wherein the keys are strings rather than integers. Here are the new members of the Hashtable object: Methods: remove(string keyName) - Remove an element by key name getAt(int index) - Get the value at the specified index getEnum[int index] - Get the key name at the specified index Properties: count - Get the number...(read more)

IIS 5.1: 403.9 - Access Forbidden: Too many users are connected

2007-01-12T02:35:45Z

I found this blog that addresses my concern in IIS 5.1 for Windows XP. I recently discovered that it is crippled in such a way that it only allows 10 concurrent connections. Moreover, it is hardcoded to be configured to at most 40. If the maximum concurrent connections have been reached, your website's users will receive the following error: HTTP 403.9 - Access Forbidden: Too many users are connected The workaround involves modifying the maximum allowable connections to 40. Still, you're...(read more)

Do JavaScript after window.close()

2007-01-09T10:59:43Z

I needed to do some routines when a user has closed the window. I do not want those routines to trigger when refreshing the page or unloading the document; I just need them to happen when the browser window is closed. This is the usual proposed solution: assign a function on the onbeforeunload event of the body or window. The problem with this is it also triggers when refreshing or moving away from the page (i.e. back or forward). I stumbled upon a solution that proposes tapping the onunload event...(read more)

BLOCKED SCRIPT How to close the browser window without the IE warning

2007-01-09T02:49:48Z

In Internet Explorer, when you use window.close() in JavaScript to close the current browser window, you will be asked something like "A script is attempting to close this window. Do you want to continue?" As a programmer, this can be annoying if you are un -maliciously closing the window. A workaround to this would be setting the window.opener property to something else. Example: In your JavaScript, have something like: function logoff() { if (confirm( "Do you want to log off?"...(read more)

Access Control Lists

2006-12-14T12:19:07Z

Ever had Windows XP crash? And worse comes to worse you had to reformat your PC and you need to back up your data? The BIG problem is: you can't access your folders! Well, here's a workaround I've gathered around the net (that is yet to be personally tested). It is however assumed that you haven't encrypted (i.e. files with green filenames) your files. That is "irreversible" and thus cannot be recovered. 1. Use your drive as a slave drive in another computer. The master...(read more)

ArrayList sorting via IComparable

2006-11-27T15:13:57Z

The problem: I have a two-dimensional object array. Each first level element of the array contains five object elements--except for the last one, which only has three. However, I have a procedure that needs to concatenate another array at the end of the original one. Since I need to put the unique three-element object array at the end of the list, I had to find a solution to sort it via the elements' length. The immediate solution was to use ArrayList.Sort(IComparer). Okay I created a class that...(read more)

Predicates in dotNet

2006-11-20T01:20:17Z

I've come across Predicates in dotNet 2.0. I felt so disgusted with too many foreach loops when looping through list collections. So, here was my problem: I have three string Lists, say, A, B and C. List string A is the reference list; while B and C contain elements found in A. By brute force method (and practically the only way we can do it in dotNet 1.x), we do something like: foreach ( string strA in A) { foreach ( string strB in B) { if (strB.Contains(strB)) { /* do something... */ } } foreach...(read more)

Selecting Xml Nodes in MSXML 3 via XPath

2006-11-15T23:39:53Z

Apparently, you need to set the SelectionLanguage property of a JavaScript XML Document object to XPath so you can select nodes via XPath. var xmldoc = new ActiveXObject("Microsoft.XMLDOM"); // or var xmldoc = new ActiveXObject('Msxml2.DOMDocument.3.0'); xmldoc.async = "false"; xmldoc.loadXML(xmlData); xmldoc.setProperty( "SelectionLanguage" , "XPath" ); After which you can use XPath to select nodes. This is inevitable for MSXML 3....(read more)
