User interface standards for a server application only affect the window's title bar and one or two of its menus and a message box. For more information about UI standards for OLE, see Chapter 3, "OLE User Interface."
All UI changes affect a server application started for embedding; when a server application is opened for linking it appears just as if it were started as a stand-alone application. In the linking mode, the application needs to implement OLE calls when it saves and changes documents, and when it informs the client application of these actions.
