Adding a Message Handler

|  Overview |  How Do I | 

You can use ClassView, WizardBar, or ClassWizard to add a message handler (a member function that handles Windows messages) to a class, and map Windows messages to the message handler. You can also quickly add a message handler for any dialog box control.

ClassWizard and WizardBar let you browse the messages associated with user-interface objects in your project. Both tools automatically update the message-dispatch table, or message map, and your class header file when you use them to define message-handling functions.

Note   Adding a message handler to an ATL class is performed in the same way that you add a message handler to an MFC class, however some results may vary. For more information, see the topic
