问题
I have a fairly simple MFC app that just defines its own sub-classes of CDocument, CView and CFrameWnd and uses them via a CSingleDocTemplate to display the read-only contents of the document in a tree on the view. All very standard MFC MVC.
I now need to convert this app so that it works as an ActiveX control that I can then embed it within a larger application.
How should I go about this?
Is it possible to use the COleControl sub-class in place of the CFrameWnd sub-class in the CSingleDocTemplate? Or do I need to place the CFrameWnd sub-class within the COleControl some how?
Failing that, how can I use my existing CDocument\CView sub-classes within an ActiveX control?

Answering my own question: I found quite a few references to an old article about this, which used to be at http://www.microsoft.com/mind/0497/mfc.asp but has long since disappeared. :(
Fortunately though, the Wayback Machine still has a complete copy of it:
"Designing ActiveX Components with the MFC Document/View Model" by Steve Zimmerman, Microsoft Interactive Developer (April 1997)
Steve presents source code for two new classes:
CActiveXDocTemplate : a sub-class of CSingleDocTemplateCActiveXDocControl : a sub-class of COleControl
which allowed me to use my existing CView and CDocument sub-classes in an ActiveX control.
(Thanks Steve wherever you are now)
