Hi,

As you did not specify which language you are doing this, I can recommend you to post your question in one of the forums below: 

http://social.msdn.microsoft.com/Forums/en-US/csharplanguage/threads - C# Language Forum
http://social.msdn.microsoft.com/Forums/en-US/vclanguage/threads - C++ Language Forum
http://social.msdn.microsoft.com/Forums/en-US/vblanguage/threads - VB Language Forum

This forum is intended just to ask where is the best place for posting questions such as that. In one of those they'll be probably of more help.
