If you purchased the first edition, then the book was published by the original Wrox Press, and Wiley has since purchased the brand and several of the titles. Unfortunately we don't have the code files from the first edition for this title since it was published before the purchase. However, if you own the second edition, or if you want to see if the files are somewhat similar, you can download the code at this site:

If you have the third edition, you can download the code from this location:
http://www.wrox.com/WileyCDA/WroxTit...load_code.html
I am sorry I can't be of more help!
