SecondaryBuffer.SecondaryBuffer(Stream,Device) Constructor (Microsoft.DirectX.DirectSound)

Initializes a new instance of the SecondaryBuffer class.

Definition

Visual Basic	Public Sub New( _     ByVal source As Stream, _     ByVal parent As Device _ )
C#	public SecondaryBuffer(     Stream source,     Device parent );
C++	public:  SecondaryBuffer(     Stream^ source,     Device^ parent );
JScript	public function SecondaryBuffer(     source : Stream,     parent : Device );

Parameters

source	System.IO.Stream A Stream object that contains the source data for the buffer.
parent	Microsoft.DirectX.DirectSound.Device A Device object that represents the parent device to use with the buffer.

Remarks

**Note: **If the method succeeds, to determine whether a requested 3-D algorithm was available or not, and stereo panning was substituted, check the Buffer.NotVirtualized property.

Microsoft DirectSound does not initialize the contents of the buffer, and the application cannot assume that it contains silence.

If an attempt is made to create a buffer with LocateInHardware set to true in the BufferDescription on a system where hardware acceleration is not available, the method fails throwing either ControlUnavailableException or InvalidCallException, depending on the operating system.

If an attempt is made to create a buffer with Control3D set to true in the BufferDescription and you attempt to load the buffer with a stero sound, the method fails throwing a ArgumentException.

Exceptions

AllocatedException

The request failed because resources, such as a priority level, were already in use by another caller.

ArgumentException

An invalid parameter was passed to the called method.

ArgumentNullException

One or more of the parameters is null.

BadFormatException

The specified wave format is not supported.

BufferTooSmallException

The buffer size is not large enough to enable effects processing.

ControlUnavailableException

The buffer control (volume, pan, and so on) requested by the caller is not available. Controls must be specified when the buffer is created.

InvalidCallException

The method call is invalid for the current state of this object.

NoAggregationException

OutOfMemoryException

DirectSound could not allocate sufficient memory to complete the call.
