Description
Responds to notifications of changes in the combo box.
CNNotify is called automatically in response to notification messages from Windows that there has been a change in the combo box. It checks the notification code, and if it is a notification that the user started or stopped editing, generates an OnBeginEdit or OnEndEdit event, as appropriate.
Message represents the parameters of the Windows message that informs the combo box of the change.
