Stamatakis' book begins with an intro to both design patterns (Object Oriented methodologies) and the OOP methodology of Visual Basic. He goes over the Visual Basic implementation of OOP and shows methods to get around areas where VB falls short. He then covers the basics of COM necessary to creating distributed (Object based) software. The rest of the book covers individual patterns of VB OO development and includes scenarios for use, ramifications of using along with copious example code (the CD sample code alone is worth the ticket price).

The book borrows from Design Patterns (Erich Gamma, et al) and applies the theory to Visual Basic development. If you are serious about developing VB COM components, this book should be part of your library.
