CWinApp::ProcessMessageFilter

The framework's hook function calls this member function to filter and respond to certain Windows messages.

virtual BOOL ProcessMessageFilter( 
   int code, 
   LPMSG lpMsg  
);

code

Specifies a hook code. This member function uses the code to determine how to process lpMsg.

lpMsg

A pointer to a Windows MSG structure.

Nonzero if the message is processed; otherwise 0.

A hook function processes events before they are sent to the application's normal message processing.

If you override this advanced feature, be sure to call the base-class version to maintain the framework's hook processing.
