hello this is prashant.
well i need to find some helping materials online on WTL coz even microsoft site isnt having any sort of documentation in this.also can someone give me few examples in this as to how to create a dialog boxes & few other stuff.thanks in advance.

Not certain but WTL might be dead, and it was never officially supported by Microsoft. You are better off using wxWidgets, which is portable to several operating systems, compilers, and used by lots of programmers. There are also several tutorials that you can find with google.
