How This Book Is Structured
This book is grouped into four distinct sections. The first is the introductory section, which contains information about the Windows operating system and the basics of subclassing and hooking. This section lays the foundation that will enable you to completely grasp the rest of the material in this book. This section contains the following chapters:
- Chapter 1
This chapter defines subclassing and hooking and gives several examples of how each can be used effectively. In addition, the tools used in this book are explained. The tools include the following:
Spy++, which enables us to view information about processes, windows, and messages. This tool comes as part of the Visual Studio Version 6 development environment.
The Dbgwproc.dll DLL, which enables us to more easily debug subclassing code within projects written in Versions 5 or 6 of VB. This tool can be downloaded from http://msdn.microsoft.com/vbasic/downloads/controls.asp.
Microsoft System Information, which enables us to see the installed hooks in a Windows 98 system. This tool can be accessed from the Help → About Microsoft Visual Basic... menu item on the Visual Basic main menu bar. When the About dialog box appears, click the System Info... button to view the Microsoft System Information tool.
SmartCheck, developed by Compuware Numega Labs, which enables us to watch under the hood as a VB project runs. A 14-day trial version of this software is available from Compuware Numega Labs at http://www.numega.com/evaluations/default.asp ...
