Peter seems to know what he's talking about. Unfortunately the book is FULL of mistakes. Peter codes in VB, and the C# translations that he provides were obviously not tested. They were copied and pasted from the VB code and only half translated. They don't even come close to compiling. I would have hoped downloading the code from the wrox website would have provided the fixes, but unfortunately they rushed this one out, and didn't look back.
