I have had this annoying problem with FireFox for a while: when I try to bookmark a web page, the “Add Bookmark” dialog does not respond after I click “Add”. If I select a different folder to save the bookmark, the “Add Bookmark” dialog will respond but only add the bookmark without a name – a blank bookmark entry pointing to the web page. I didn’t use FireFox as much as I do now, so […]
I am a .NET developer and work with the Windows platform almost all the time, then why Linux out of a sudden? The reason is Virtulization. Every developer should have some kind of virtulization tool to help them test their applications under different environments. Microsoft’s Virtual PC may be an option. But the problem with MS Virtual PC is that if I install it on my Windows PC, then I have to maintain the security […]
I got a 503 error message the other day when I was trying to write a post, which made me love the WordPress developers more. Why? Look at the screenshot of the error message and you will see: BTW, “Matt” is one of their developers. Don’t you love these guys? Maybe I should ask my supervisor if I can write an error message like this and put his name in it. 🙂
Just in case you have not heard about it, Reflector, a must-have for .NET developers, was released version 5.0.

The For and For Each loops let you define their controlling variable as a block variable, using this syntax: For i As Integer = 1 To 10 … Next This syntax was introduced in Visual Studio.NET 2003. Many books and articles, however, continue to use the old syntax: Dim i As Integer For i = 1 To 10 … Next The new syntax is preferred in all cases because it prevents you from accidentally reusing […]
In the part one and part two of AJAX Drop Down List tutorial, I have described how to populate a drop down list with plain string data and XML string data respectively. If you followed the first two parts of the tutorial and built your drop down list, you will probably notice that you cannot use “ddlChildList.SelectedValue” to retrieve the value from the drop down list. The reason is that the drop down list is […]
