Programming Notes

The application sets up a notification of type DMUS_NOTIFY_ON_SEGMENT, which triggers the DirectXEvent8_DXCallback procedure on various segment-related events. In the callback procedure, the subtype of the notification message is checked to see if the segment has stopped playing. If it has, the user interface is updated to enable play options.
