Description
Occurs when an application becomes active.
Write an OnActivate event handler to perform special processing when the application becomes active.
An application becomes active when it is initially run or when focus moves from another Windows application back to any window of the application.
Note: Call the CancelDispatch method from an OnActivate event handler to prevent the application from forwarding the event to any other application events objects.
OnActivate is an event handler of type TNotifyEvent.
