The framework calls this member function after each interval specified in the SetTimer member function used to install a timer.

afx_msg void OnTimer( 
   UINT_PTR nIDEvent  


Specifies the identifier of the timer.

The DispatchMessage Windows function sends a WM_TIMER message when no other messages are in the application's message queue.


This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.

See the example in CWnd::SetTimer.
