Commits all DirectComposition commands that are pending on this device.
HRESULT Commit( );
This method has no parameters.
If the function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code. See DirectComposition Error Codes for a list of error codes.
Calls to DirectComposition methods are always batched and executed atomically as a single transaction. Calls take effect only when IDCompositionDevice::Commit is called, at which time all pending method calls for a device are executed at once.
An application that uses multiple devices must call Commit for each device separately. However, because the composition engine processes the calls individually, the batch of commands might not take effect at the same time.
For an example, see How to Build a Simple Visual Tree.
