I don't know what you are talking about. Here are the relevant parts of
atlctl.h:

template <class T>
class CComCompositeControl : public CComControl< T, CAxDialogImpl< T > >
{...}

template <class T, class WinBase = CWindowImpl< T > >
class ATL_NO_VTABLE CComControl : public CComControlBase, public
WinBase
{...}

So, if you have

CMyControl : public CComCompositeControl<CMyControl>

your class is derived from CComCompositeControl<CMyControl> which is
derived from CComControl<CMyControl, CAxDialogImpl<CMyControl> > which
is derived from CComControlBase and CAxDialogImpl<CMyControl>. I don't
know how to make it any clearer.

CWindow::GetDlgControl. Before you ask, your class _is_ indeed derived
from CWindow.
