Initializes a new instance of the Buffer class.


Visual Basic Public Sub New( _
    ByVal fileName As String, _
    ByVal parent As Device _
C# public Buffer(
    string fileName,
    Device parent
C++ public:
    StringLeave SitefileName,
JScript public function Buffer(
    fileName : String,
    parent : Device


fileName System.String
A StringLeave Site that represents the file name of the file that contains source data for the buffer.
parent Microsoft.DirectX.DirectSound.Device
A Device object that represents the parent device to use with the buffer.


**Note: **If the method succeeds, check the Buffer.NotVirtualized property to determine whether a requested 3-D algorithm was available and stereo panning was substituted.

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 BufferCaps.LocateInHardware set to true on a system where hardware acceleration is not available, the method fails throwing either ControlUnavailableException or InvalidCallException, depending upon the operating system.



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

ArgumentExceptionLeave Site

An invalid parameter was passed to the called method.

ArgumentNullExceptionLeave Site

One or more of the parameters is null.


The specified wave format is not supported.


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


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


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


The object does not support aggregation.

OutOfMemoryExceptionLeave Site

DirectSound could not allocate sufficient memory to complete the call.


The function called is not supported at this time.
