Book excerpt: This long-awaited complement to Appleman's previous bestseller shows programmers how to turbocharge VB by describing how to control the entire Windows API. Divided into three parts, the book begins with a series of programming puzzles of increasing complexity. Each puzzle describes a typical API function, followed by a small VB program applying the function. These programs almost work but are all missing something. Readers are challenged to solve the puzzle and fix the program -- thus learning in the process. The second part contains solutions to the puzzles, along with in-depth technical explanations, while the final part concludes with general tutorials that readers can refer to for help in solving the problems.
