Visual Basic Public Property ControlPositionNotify As Boolean
C# public bool ControlPositionNotify { get; set; }

        bool get();
        void set(bool value);

Property Value

This value is set to true if the buffer has position notification capability; otherwise, false.

This property is read/write. 


Because the virtual device driver model (VXD) does not support notifications, a sound buffer created with BufferDescription.ControlPositionNotify set to true is always a software buffer when using VXD drivers. With the Windows Driver Model (WDM), a notification-enabled buffer can be in hardware, if hardware resources are available.
