Step 4: Close Down

To exit an audio application cleanly, you must perform three main steps:

• Stop any playing segments by calling DirectMusicPerformance8.StopEx.
• Close down the performance. The DirectMusicPerformance8.CloseDown method performs miscellaneous cleanup tasks and releases internal references to objects.
• Release all objects by setting object variables to Nothing.

The following procedure from the sample application closes down DirectX Audio:

Private Sub Form_Unload(Cancel As Integer)
  If Not (seg Is Nothing) Then 
    dmp.StopEx dmp.GetDefaultAudioPath, 0, 0
  End If
  Set seg = Nothing
  dmp.CloseDown
  Set dmp = Nothing
  Set dml = Nothing
  Set dx = Nothing
End Sub
