Query: This books s***s

I have only read the first 5 chapters, but I quit this book gives no examples, the source code doesn't even compile. and there is no explanations of any of the vocabulary words this guy used in his book. (What the heck is a BLit?) There has got to be a better book out there on Direct X?, in this book all he does it talk talk talk talk, and doesnt explain how to do anything, this book more teaches you about direct x...doesnt really teach you anything on how to use it.
