Query: False advertising: 1) not a reference 2) code not available

This is fairly shallow to be considered a reference.Notably, Wrox seems to have removed its "forum" for this book - perhaps it was not more friendly than these reviews...Wrox's failure to deliver on the code it advertises both on the front cover and inside the book should be taken as a warning not to trust this publisher - even though there is hardly any useful code.
