This is a terrible book on DirectX. It seems that the author doesn't want to teach you DirectX, but would rather just have you cut and paste his code into your program and use it without understanding how it works. Example: "We won't dig into code here; we'll just skim over it..."(166). That is no way to teach someone. He makes DirectDraw much more complicated than it really is. I do know a good bit of DirectX now, but no thanks to this book. Also, all of his programs are poor quality. I still consider myself a beginner DirectX programmer, but I can thow together better programs in one day, no joke, they're that bad!
