The following information is intended for application developers. There are different methods for programming Help in applications, depending on the kind of context-sensitive Help involved.
HWND HtmlHelp(Window(), “c:\path\helpfile.chm”, HH_HELP_CONTEXT, Number);
HWND HtmlHelp (Window(), “c:\path\helpfile.chm”, HH_DISPLAY_TOPIC, "topicfile.htm");
The method for programming What’s This? Help in your application depends on the way the context-sensitive Help was created.
If the Help was created in RoboHELP as text-only topic files, refer to your Software Development Kit for details.
If the Help was created in What’s This? Help Composer, see Adding What’s This? Help to C/C++ applications.
Note: For further information about programming Help in Windows applications, see the HTML Help API Reference at http://msdn.microsoft.com/workshop/author/htmlhelp/hhapi.asp.
