Message-Mapping Tasks

|  Overview |  Details | 

Use MFC message mapping to connect specific Windows messages to handler functions. You can specify which object in your program handles a message (although some objects, such as documents, can handle only command messages, not window messages). ClassWizard and WizardBar help you map messages easily.

For general information about messages and message queues in Windows, see in the Win32 Programmer's Reference.
