Get realistic, we are not here to do your migration work for you.

Learn VB.Net, rewrite your code, then come back when you have a specific question.

Oh. Thanks for your kind reply.

I did a major VBA to VB.Net migration a couple of years ago and, seriously, there's a lot more to it than just converting code. You have to learn Visual Studio - at least enough to create a project, edit, debug (it's a LOT different than VBA), publish and install the compiled code, etc.

By far the most useful book for me was Visual Studio Tools for Office Using Visual Basic 2005. There's also a book for the 2008 version but if's oriented towards C#. If you or your company aren't willing to invest the time necessary to learn these basics, I recommend you stick with VBA.
