Menu Switching

I'm working in a multi-Doc application with no Doc-view arch. Just different child frame are loaded in the main frame. Each child frame is dynamically loaded from a separate dll. I need to switch to a different menu with each child frame. So, I simply load each menu in its dll

 

int CModuleFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)

{

   ...

   HINSTANCE hClientResources = AfxGetResourceHandle();

   HINSTANCE hnewInst = ::GetModuleHandle(_T("Module1.dll"));
   AfxSetResourceHandle(hnewInst);

}

 

and then set it on the MDI activation message.

 

void CModuleFrame::OnMDIActivate(BOOL bActivate,CWnd* pActivateWnd,CWnd* pDeactivateWnd)
{
     CMDIFrameWnd* pFrame = GetMDIFrame();
     if (pFrame)
    {
        ::SendMessage(pFrame->m_hWndMDIClient, WM_MDISETMENU,  (WPARAM)m_hMenuShared, (LPARAM)NULL);
        pFrame->DrawMenuBar();
    }
}

 

but this doesn't work?

 

Am I missing something??

 

Thanks

 

BUT, is it good to load the menu each time the frame is switched? Don't I need to free (unload) something before each loading?

 

Also, what is the best way to restore the Mainframe menu when closing all the child frames?
