| Microsoft DirectX 8.1 (Visual Basic) |
In DirectX for Visual Basic, performance parameters are set and retrieved by using various methods of DirectMusicPerformance8 and DirectMusicSegment8.
To have the performance respond immediately to a changed parameter, an application can flush messages from the queue by using the DirectMusicPerformance8.Invalidate method. This method causes all tracks to resend messages from the specified point forward.
