MFC CRichEditView vs CRichEditCtrl

I was looking at the source code of CRichEditView::GetRichEditCtrl and it looks like they are type casting the view into a ctrl (even though there is no inheritence or subobject of the appropriate type). I've been looking into this but I thought I'd as how these two classes even line up? They don't appear to have much in common, but at the top of the CRichEditCtrl class it mentions:

This class must remain a binary-compatible subset of CRichEditView. Do not add data members or virtual functions directly to this class.

Can someone explain how to "view" these corresponding classes, in spite of their differences. Examples (especially related to CRichEditCtrl/View appreciated), as I'm not really understanding the linkage.

Have a look at http://msdn.microsoft.com/en-us/magazine/cc301457.aspx

Wow that article was dead on, thank you VictorN.

SHouldn't this trick still be possible if you derived a custom class directly from CView, instead of deriving from CCtrlView? Since They are both derived from CWnd (eventually) and you're only interested in using h_Wnd.

What would be the benefit of deriving from CCtrlView?

In the link that Victor gave, Paul describes the differences in the section where he talks about the CCtrlView. Essentially CCtrlView adds a property and a couple of methods to CView. You certainly could add this to a class derived directly from CView, but what would that get you (since it's already done for you)?
