"DirectX User Interfaces" book

Interfaces are much simpler than they sound. By implementing an interface you are simply agreeing to implement all the methods of the interface. Affectively allowing your class to communicate with other classes and methods. I believe one of the simplest interfaces to learn is the IEnumerable interface. This interface allows your class to be accessed with the foreach statement. By implementing this interface you are guaranteeing to implement the GetEnumerator method.

I haven't looked to much into Interfaces with DirectX, but the concept of interfaces themselves is pretty straightforward. What methods and how to implement them, depends on the interface.

I believe he's talking about user interfaces, not abstract interfaces.

The book is based on the Summer 2003 version of the SDK. That may explain why your having issues with the source code. There have been a number of changes in the SDK since then.

im currently using the User Interface development book by wordware to make an actual user interface for my game and ive noticed a lot of the code in the book is wrong. The declared constructors for the Texture/Surface class are recursive - they go on forever creating themselves.

Looking on the bright side though the advantage of all these mistakes is that it raises your concentration as you are wary of errors.

Hmm... it does appear your right. :!

Interesting, if anyone knows of any other source of information on the subject, let me know.
