Editing a Message Handler

Home |  Overview |  How Do I |  Tutorial

Once you have defined a message handler with ClassWizard or WizardBar, you can use either tool to go to the member function's definition to add or modify code.

Note   There is no support for editing message handlers of ATL objects using ClassWizard.

If you have the dialog editor open, double-click on a control for which a handler is already defined. This navigates you to the file in which the selected control's message handler is defined.

To jump to a member function definition with WizardBar

1. Using WizardBar, select the class from the Class drop-down list, and the member function from the Member drop-down list.
   
   
2. The WizardBar automatically navigates to the location in the implementation file in which the selected member function is defined.
   
   
3. Subsequent clicks on the Action button navigate alternately between the function's definition and declaration.
