Simpcntr

--------

This sample is the simplest OLE 2.0 container that can be written and

still support the visual editing feature.  The sample has no native

file format, and can only support one OLE object at a time.  The

Insert Object command is used to create an object.



See the MAKEFILE for compilation instructions.





Simple Container Objects Overview :

-----------------------------------

Simple Container consists of three main objects. The top level is CSimpleApp,

under which is CSimpleDoc, and the innermost level is CSimpleSite. CSimpleApp

is used to hold the main window information. (eg. handle to the main window,

handle to the UI Active Object) CSimpleApp always exists as long as the

simple container application is alive. It demonstrates the implementation of

IOleInPlaceFrame, in its nested class COleInPlaceFrame.



The next level object is CSimpleDoc object. It is instantiated by CSimpleApp

when a new document is created. It is used to hold the handles to the main

menus and the submenus and manipulate changes to these menus.



The CSimpleDoc object instantiates CSimpleSite object as the user chooses to

insert a new object into the document. CSimpleSite demonstrates the

implementation of IAdviseSink, IOleInPlaceSite and IOleClientSite through

its nested classes. These interfaces are implemented as CAdviseSink,

COleInPlaceSite and COleClientSite accordingly. CSimpleSite acts as a client

site to communicate to a remote server.
