The object that this server +supports 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.CSimpSvrApp +is used to hold all the main window information. (eg. handle to the main +window, handles to the main, color, and help menus and the application +instance) Therefore, CSimpSvrApp always exists as long as the simple server +application is alive. The CSimpSvrApp instantiates the Class Factory, if +simple server is started as embedding. (ie. started by OLE) The next level +object is CSimpSvrDoc object. It is instantiated by the time CSimpSvrApp is +created. It manipulates the document window and also the hatch window. +(See OLE2UI for detail on the hatch window) The CSimpSvrObj, the innermost +simple server object, shows six OLE interfaces implementations in its nested +classes. 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 object +and all the OLE connections between the container and the server. + + + +
