ISpThreadTask::WindowMessage (Windows Embedded CE 6.0)
1/6/2010
This application-specific method processes window messages, if the application needs a window. If the caller of ISpThreadControl::StartThread passes a non-null window pointer, this method must be implemented. In this case, the implementation must use a MessageWaitForMultipleObjects loop in its ISpThreadTask::ThreadProc method.
