Overview
Help technology comes in two flavors these days: HTML format and the classic WinHelp format. Microsoft Foundation Class (MFC) library application framework programs work with both WinHelp and HTML Help, but the trend is toward HTML Help. You can see an example of HTML Help in the Microsoft Visual C++ .NET online documentation.This chapter shows you how to construct and process a simple standalone help file that has a table of contents and lets the user jump between topics. You'll also learn how your MFC library program activates the help system using help context IDs derived from window and command IDs keyed to an MFC Application Wizard–generated help file. Finally, you'll learn how to use the MFC library help message routing system to customize the help capability.
