Welcome to Visual C++ Windows Shell Programming! With this book, youll learn how to program theWindows Shell, customize its behavior and integrate your applications with it. Youll discover how touse and modify its features to best effect, and the way to call shell API functions whosedocumentation is scant. Programming the shell isnt difficult, but few books explain the subject in itsentirety.This book covers the whole range of API functions in detail, often revealing bugs and undocumentedfeatures. It delves deep into the world of Explorer, bringing to light things like hooks, the registry,browser helper objects, shell extensions, namespace extensions and web views. It also looks atWindows Scripting Host extensions and Shell Scriptable Objects.This book is for professional and home developers alike, and has three main goals:Providing a better understanding of the existing and often poorly documented shell APIGiving ideas for new applicationsShowing whats new in Internet Explorer 4.x, the Active Desktop and Windows 98, and how thesefit with the existing shell.

With suitable instruction, you can push the Windows shell to performing complex actions, and customize it using C++/ATL programs. Until now, the documentation for Windows shell programming has been poor. This book is about telling you exactly how to use the tools available, and when each tool is appropriate. There's coverage of the Windows API, the Windows Scripting Host, and shell and namespace extensions that use ATL and the shell's COM object model. Information on these topics at this level has been scarce, but the author brings them all together in this volume.
