1. The VB
version is newer, but both of the code downloads are for VS 2002. You can download the code for either version from the Wrox website. Find the book, and then you'll see the links to download the code.
2. It sounds like you have a bad reference. Did you port the code to VS 2003? Both code downloads are set up for VS 2002 and you have to convert the projects and set new references to make them work in 2003.
There is no official source code for use directly in VS 2003. I was hoping Wrox would consider updating the code again, but I don't think they will.
I'd really like to see a revised edition of the book, and that could include code for the new VS 2005, which is already out in beta. There's a number of changes to the design that I've recommended, and it'd be great if we could get all this into a revised book.
