Message, CView and CWnd

I have created a Class CGraphCtrl which inherihates from CWnd.
Then I Have Created a class CGraphView which inherihates from CView.

in the OnInitialUpdate of the CGraphView I do :
m_GraphCtrl.Create(WS_VISIBLE | WS_CHILD, rect, this);

The problem is that the message that gets the View are not sent to the Ctrl ...

Do I have to use SubclassWindow ????

Thanks
