Microsoft DirectX 9.0 SDK Update (October 2004)

BufferDescription.ControlPositionNotify Property

Language:

Note: This documentation is preliminary and is subject to change.

Specifies whether the buffer has position notification capability.

Definition

Visual Basic .NET Public Property ControlPositionNotify As Boolean
C# public bool ControlPositionNotify { get; set; }
Managed C++ public: __property bool get_ControlPositionNotify();
public: __property void set_ControlPositionNotify(bool);
JScript .NET 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.
