Event Handler Wizard

This wizard adds an event handler for a dialog box control to the class of your choice. If you add an event handler from the Properties window, you can add it only to the class that implements the dialog box. See Adding Event Handlers for Dialog Box Controls for more information.

  • Command name
    Identifies the selected control, for which the event handler is added. This box is unavailable.

  • Message type
    Displays the list of current possible message handlers for the selected control.

  • Function handler name
    Displays the name of the function that is added to handle the event. By default, the name is based on the message type and the command, prepended by "On". For example, for the button called IDC_BUTTON1, the message type BN_CLICKED displays the function handler name OnBnClickedButton1.

  • Class list
    Displays available classes to which you can add an event handler. The class for the selected dialog box is displayed in red.

  • Handler description
    Provides a description for the item selected in the Message type box. This box is unavailable.

  • Add and edit
    Adds the message handler to the selected class or object, and then opens the text editor to the new function so you can add the control notification handler code.

  • Edit code
    Opens the text editor to the selected existing function so you can add or edit the control notification handler code.
