Dan Appleman's Win32 Api Puzzle Book and Tutorial for Visual Basic Programmers :

The problems start simply enough, with puzzles that look at the basics of Win32 API C API calls, such as retrieving error messages and graphics. However, the book quickly approaches tougher terrain, offering a series of problems on the Windows Registry. Other problem topics include programming with Remote Access Services (RAS), networked drives, and the DEVMODE structure (for polling printers and other devices). Finally, the toughest problems involve ActiveX programming and cover how to work with Global Universal Identifiers (GUIDs) and drag-and-drop file operations.

The back of the book contains hints for each puzzle, as well as complete solutions and comments. The author provides a tutorial on various aspects of VB Win32 C API programming, including C to VB data types, parameter passing (by value and by pointer) and some excellent material on how the call stack works for Windows DLLs. Two final sections discuss the Win32 Service API (for starting and stopping Win32 services) and how to access the Windows NT Event Log.

In all, this book provides expert knowledge on getting the most out of VB Win32 C API calls in a format that is always challenging and often entertaining. --Richard Dragan
