To add a message handler (a member function that handles Windows messages) to a control, first select the control in the Class View. Then open the Properties window, select the Messages icon, and click the drop-down control in the box opposite the required message. This will add a declaration for the message handler in the control's header file and a skeleton implementation of the handler in the control's .cpp file. It will also add the message map and add an entry for the handler.
Adding a message handler in ATL is similar to adding a message handler to an MFC class. See Adding an MFC Message Handler for more information.
The following conditions apply only to adding an ATL message handler:
-
The message handlers follow the same naming convention as MFC.
-
The new message map entries are added into the main message map. The wizard does not recognize alternate message maps and chaining.
