Oooh, be careful here. If you are talking about programming for the
Pocket PC using Visual Basic.net then you better get a book that is tailored to the "Compact Framework". Because, believe me, you will be so pissed off about how many simple functions are missing from the compact framework that the big brother has access to. I have wasted so much time typing a simple command that works in the normal VB.net but is unsupported when programming for my PPC. Then, you are left to search all over the Internet trying to find a solution. You'll quickly find that MOST Web pages are answering your question with the full VB.net commands, and not the one that works on your PPC.
Well, good luck and hope you find the answers.
