Custom controls might be required to send notifications of events to the parent window so that the host application can respond to these events.

For example, a custom list view might send a notification when the user selects an item, and another notification when an item is double-clicked. The control identifier is a unique number the application uses to identify the control sending the message.

The application sets the identifier for a control when it creates the control. Because the control itself does not set the control identifier, the control must retrieve the identifier before it can send notification messages. Although the control identifier is specified as the menu handle when the control is created, the GetMenu function cannot be used to retrieve the identifier. Note that the NMHDR structure can be part of a larger control-defined structure that contains additional information.

In the example, the old and new values of the control might be contained in this structure. All the common controls support Microsoft Active Accessibility MSAA , which enables programmatic access by accessible-technology applications such as screen-readers. Otherwise, accessible-technology products will be able to obtain only very limited information about the control window, will not have access to the control's properties, and will be unable to trigger events in the control.

You can call the Refresh method, which forces the control to redraw itself and all its children. This is equivalent to setting the Invalidate method to true and using it with Update. The Invalidate method governs what gets painted or repainted.

The Update method governs when the painting or repainting occurs. If you use the Invalidate and Update methods together rather than calling Refresh , what gets repainted depends on which overload of Invalidate you use.
