Parvez,
As advice, ask this in a language newsgroup.
In don't know about the others, however I have seen a lot of answers for
your question in the newsgroup
microsoft.public.dotnet.languages.vb
I thought that Tom Shelton is mostly answering this kind of questions so
maybe you can search than for that.
I hope this helps something,
Cor
