	In one of my recent projects, I have created a two way static splitting 
frame. Is there a way to close or reopen one of panes just by clicking a menu item ? Any help would be appreciated.

     Dennis,
     
     I have two views and allow the user to split them from the View menu 
     or toolbar (all options are mapped to this code -- whole map view, 
     whole edit view, 50/50 split) with the following code:
     
     void CMyMDIFrame::OnViewView(UINT nID)
     {
        CRect rcClient;
     
        if (nID == ID_VIEW_MAP)
                ActivateView(RUNTIME_CLASS(CMyMapView));
        else if (nID == ID_VIEW_EDITOR)
                ActivateView(RUNTIME_CLASS(CMyEditView));
        CMyMDIChild* pMDIChildWnd = (CMyMDIChild*)MDIGetActive();
        CSplitterWnd* pSplitterWnd = pMDIChildWnd->GetSplitterWnd();
        pSplitterWnd->GetClientRect(rcClient);
        pSplitterWnd->SetColumnInfo(nID == ID_VIEW_MAP ? 0 : 1, nID         
         != ID_VIEW_SPLIT ? rcClient.right : rcClient.right / 2, 1);
        pSplitterWnd->SetColumnInfo(nID == ID_VIEW_MAP ? 1 : 0, nID         
         != ID_VIEW_SPLIT ? 1 : rcClient.right / 2, 1);
        pSplitterWnd->RecalcLayout();
     }
     
     This code leaves the splitter bar "parked" along the side of the view; 
     the view is not completely hidden.

     Dennis,
     
     Try using 
        CSplitterWnd::SetColumnInfo( int col, int cxIdeal, int cxMin )
     by setting the cxMin value > then the current size and the cxIdeal 
     size you can indicate that the pane can not be displayed because there 
     is not enough room (by making cxMin > the screen size you can ensure 
     the user can never resize the splitter window to see the pane).  
     Conversely set cxMin <= cxIdeal to redisplay the pane.
     
     In both cases call CSplitterWnd::RecalcLayout() after you call to 
     SetColumnInfo().
     
     Note the following from the MFC documentation:
     "void RecalcLayout( );
       
     Remarks
     Call this member function to correctly redisplay the splitter window 
     after you have adjusted row and column sizes with the SetRowInfo and 
     SetColumnInfo member functions. If you change row and column sizes as 
     part of the creation process before the splitter window is visible, it 
     is not necessary to call this member function.
     The framework calls this member function whenever the user resizes the 
     splitter window or moves a split."
