Wow. What this tells me is that you're able to use google to find code, but don't have the most basic idea of what it does. I suggest reading a VB.NET book or two before you do anything else.

Why?? You already have the code. If you can't figure out how to call it, you're skills are in great need of improvement. What you want to do is pretty much in any introductory course to programming and in the first couple of chapters in any VB.NET beginners book. We could tell you how to do it, but you wouldn't understand the answer.
