Software Diagnostics Institute

The books explains various Win32 API quirks, digs into internals of Windows dialog manager, Visual C++ compiler (class layout) and discusses many other less known facts. A must read book for any Win32 API developer (even experienced). The author worked in application compatibility team and provides real insight into various components of Windows GUI and user interface and explains why they work in certain ways. I even found a couple of bugs in my own tools after reading this book. The section about Windows dialog manager and message delivery is very enlightening.

Highly recommended.
