Simpsvr--------This sample is the simplest OLE 2.0 object that can be written andstill support the visual editing feature. The object that this serversupports is a colored square with a black border.
See the MAKEFILE for compilation instructions.
Simple Server Objects Overview------------------------------Simple server consists of three main objects. The top level is CSimpSvrApp,under which is CSimpSvrDoc, and the innermost level is CSimpSvrObj.CSimpSvrAppis used to hold all the main window information. (eg. handle to the mainwindow, handles to the main, color, and help menus and the applicationinstance) Therefore, CSimpSvrApp always exists as long as the simple serverapplication is alive. The CSimpSvrApp instantiates the Class Factory, ifsimple server is started as embedding. (ie. started by OLE) The next levelobject is CSimpSvrDoc object. It is instantiated by the time CSimpSvrApp iscreated. It manipulates the document window and also the hatch window.(See OLE2UI for detail on the hatch window) The CSimpSvrObj, the innermostsimple server object, shows six OLE interfaces implementations in its nestedclasses. The six OLE interfaces demonstrated are IOleObject, IPersistStorage,IDataObject,IOleInPlaceActiveObject,IOleInPlaceObject,and IExternalConnection.These six interfaces are implemented as different classes namely: COleObject,CPersistStorage, CDataObject, COleInPlaceActiveObject, COleInPlaceObject,and CExternalConnection. The CSimpSvrObj handles the drawing of the objectand all the OLE connections between the container and the server.
