Well, I checked and the code is missing. I'm not at home right now, so I can't check to see if I submitted the code to Wrox, or not. In most cases, I think you'll find almost all of the programs are available from Wrox. (There may be a few short programs not included.) Perhaps the admin for this site could post the code?
Anyway, if you have issues with the code in the book, let us know here.
