When the class associated with the implementation file is selected in the Class drop-down list, the Filter drop-down list displays Windows messages, and the Members drop-down list displays all of the member functions and data members for the selected class.
When you select a function without a handler, ClassWizard displays a message box that asks whether you want to create a handler for the function. If you respond Yes, ClassWizard creates a starter function with the correct parameters and syntax, highlighting the // TODO comment so you can replace it with your code.
