DirectSound.SetCooperativeLevel

The DirectSound.SetCooperativeLevel method sets the cooperative level of the application for this sound device.

object.SetCooperativeLevel(hwnd As Long, _
    level As CONST_DSSCLFLAGS)

Parameters

object

Object expression that resolves to a DirectSound object.

hwnd

Window handle to the application. See Remarks.

level

Requested priority level. Must be a constant of the CONST_DSSCLFLAGS enumeration.

Error Codes

If the method fails, an error is raised and Err.Number may be one of the following error values.

Remarks

The application must set the cooperative level by calling this method before its buffers can be played. The recommended cooperative level is DSSCL_PRIORITY; use other priority levels when necessary.

The hwnd parameter should be the top-level application window handle. If you are also using DirectDraw, it must be the same handle passed to the DirectDraw7.SetCooperativeLevel method.
