from the MFC sources:

The inheritance tree
CObject <- CCmdTarget <- CWnd <- CView <- CCtrlView <- CListView
                         CWmd <- CListCtrl


_AFXCVIEW_INLINE CListView::CListView() : CCtrlView(WC_LISTVIEW,
	AFX_WS_DEFAULT_VIEW)
	{ }
_AFXCVIEW_INLINE CListCtrl& CListView::GetListCtrl() const
	{ return *(CListCtrl*)this; }


no wonder they need pointer casts to be posible in C# :-)
