Add an event

  • Стаття

From Class View, you can add an event using the add event wizard only to the control class in your MFC ActiveX control project. If you want to add an event to another type of project, use the Events button in the Properties window.

To add an event to your MFC ActiveX control project:

  1. In Class View, expand the project node to display the classes in the project.

  2. Right-click the project's control class.

  3. On the shortcut menu, choose Add, and then choose Add Event to display the Add Event Wizard.

  4. Provide the event information in the appropriate wizard boxes.

  5. Select Finish to add the event to the project.

Add event wizard

This wizard adds an event to an MFC ActiveX control project. You can specify your own event, customize a typical stock event, or select from a list of stock events.

  • Event name

    Sets the name used by Automation clients to request an event from the class. Enter a name or select one from the list.

  • Event type

    Indicates the type of event to add. Available only if you select from the Event name list.

    Option Description
    Stock Specifies that a stock event, such as a button click, will be implemented for this class. Stock events are defined in the Microsoft Foundation Class (MFC) Library.
    Custom Specifies that you're using your own implementation of the event.

  • Internal name

    Sets the name of the member function that sends the event. Available only for custom events. The name is based on Event name. You can change the internal name if you want to provide a name different than Event name.

  • Parameter type

    Sets the type for the Parameter name. Select the type from the list.

  • Parameter name

    Sets the name of a parameter to pass through your event. After typing the name, you must select Add to add it the list of parameters.

    Once you select Add, the parameter name appears in Parameter list.

    Note

    If you supply a parameter name and then select Finish before you select Add, then the parameter isn't added to the event. You must find the method and insert the parameter manually.

  • Add

    Adds the parameter you specify in Parameter name, and its type, to Parameter list. Select Add to add a parameter to the list.

  • Remove

    Removes the parameter you select in Parameter list from the list.

  • Parameter list

    Displays all parameters and their types currently added for the method. As you add parameters, the wizard updates Parameter list to display each parameter with its type.
