Parameters

sourceRectangle
A Rectangle that contains the source rectangle. If the rectangle exceeds the source surface, it is clipped to the source surface. This parameter can be used only if the swap chain was created with Copy.

destRectangle
A Rectangle that contains the destination rectangle. This parameter can be used only if the swap chain was created with Copy.

overrideWindow
Must be a null reference (Nothing in Visual Basic).

Exceptions

Exception type	Condition
DriverInternalErrorException	Internal driver error. Applications should generally shut down when receiving this error.
DeviceLostException	The device is lost but cannot be reset at this time. Therefore, rendering is not possible.
InvalidCallException	The method call is invalid. For example, a method's parameter might contain an invalid value.

Remarks

If necessary, a stretch operation is applied to transfer the pixels within the source rectangle to the destination rectangle in the client area of the target window.

This method fails and throws an InvalidCallException exception if it is called between BeginScene and EndScene pairs, unless the render target is not the current render target such as the back buffer that results from the creation of an additional swap chain.
