Since this seems to be the single most popular question on the site, here's the answer from the FAQ:

I need to get the code for my Wrox book. Where can I download it?
The source code for all Wrox titles available through Wiley is available via the Download Code link at the top of all Wrox.com pages. (http://www.wrox.com/go/downloads)

What happened to the code downloads for the rest of the Wrox books?
We only own the rights to the code that goes with the works we purchased and new works we will publish. (See the all Wrox books list at: http://www.wrox.com/WileyCDA/Section/id-105077.html).

Please contact Apress (http://www.apress.com/info/contact) for information about obtaining code downloads and support for any other former Wrox books. Unfortunately, Apress's site states "The source code downloads that accompany books published by Wrox are no longer supported on this site. We apologize for any inconvenience." You'll have to ask them why.

If you have questions about code downloads, please read the Download Code FAQ.
