The DetachWindow method causes DirectSkin to stop skinning.  All look and feel will revert back to the regular windows style.  Typically this method is called when a program is cleaning up and the process is going to be destroyed.

hWnd

Handle to the main window of the application.

This method does not return a value.

After this method is called, the DoWindow method will need to be called to resume skinning. This method must be called before calling UndoWB on skinning termination. The hWnd parameter is a legacy parameter and should be 0.
