BufferDescription.ControlPositionNotify Property (Microsoft.DirectX.DirectSound)
Specifies whether the buffer has position notification capability.
Definition
Visual Basic Public Property ControlPositionNotify As Boolean C# public bool ControlPositionNotify { get; set; } C++ public:
property bool ControlPositionNotify {
bool get();
void set(bool value);
}JScript public function get ControlPositionNotify() : boolean
public function set ControlPositionNotify(boolean);
Property Value
System.Boolean
This value is set to true if the buffer has position notification capability; otherwise, false.This property is read/write.
Remarks
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.
