From the FAQ:
Why can't I find my Wrox book on your list of downloadable code?
You may have a Wrox book that was not purchased by Wiley Publishing. Previously, Wrox.com had maintained the code downloads for all Wrox books as a public service to the Wrox community. However, Wiley Publishing owns the rights only to the code belonging to the books that Wiley purchased when Wiley acquired Wrox in April 2003, as well as to new books that Wiley has published and will publish. (See the All Books page for a complete list of Wrox books owned and published by Wiley Publishing.) Therefore, Wrox.com can no longer provide the code for the Wrox books that it doesn't own.
Apress now owns all the other former Wrox books; please contact Apress for information about obtaining code downloads and support for any former Wrox book that does not appear on this site.
Apress' website also appears to not support the book.
This is absolutely ridiculous. Wrox has lost any faith I may have once had in them. They won't be getting my money again.
