Error Codes

If the method fails, it raises an error, and Err.Number can be set to one of the following values:

Remarks

The method returns True only if the segment or segment state is actually playing at the speakers. Because of latency, this method might return False even though DirectMusicPerformance8.PlaySegmentEx has just been called on the segment. Similarly, the method returns True as long as the segment is being heard, even though all messages might already have been dispatched.
