The CompleteConnect method notifies the window that the renderer's input pin has been connected.
This method resets the window activation flag (CBaseWindow::m_bActivated) to FALSE. When a video renderer completes a pin connection, it might call the CBaseWindow::ActivateWindow method to set the window's size and position. To force ActivateWindow to recalculate these attributes, first call the CompleteConnect method.
