                          PRINT PREVIEW SETTINGS


   Add this in the message map off a CView derived class :

     ON_COMMAND(ID_FILE_PRINT_PREVIEW, CView::OnFilePrintPreview)

   Add these functions to the derived CView class :

     void CXListView::OnBeginPrinting(CDC *pDC, CPrintInfo *pInfo)
      {
       m_cPrintListCtrl.OnBeginPrinting(pDC, pInfo);
       CListView::OnBeginPrinting(pDC, pInfo);
      }

     void CXListView::OnEndPrinting(CDC *pDC, CPrintInfo *pInfo)
      {
       m_cPrintListCtrl.OnEndPrinting(pDC, pInfo);
       CListView::OnEndPrinting(pDC, pInfo);
      }

     BOOL CXListView::OnPreparePrinting(CPrintInfo *pInfo)
      {
       CListCtrl &cList = GetListCtrl();
       HWND       hWnd  = cList.m_hWnd;

       m_cPrintListCtrl.SetListCtrl(hWnd);
       m_cPrintListCtrl.OnPreparePrinting(pInfo, GetDocument()->GetTitle());
   
       return DoPreparePrinting(pInfo);
      }

     void CXListView::OnPrint(CDC *pDC, CPrintInfo *pInfo)
      {
       m_cPrintListCtrl.OnPrint(pDC, pInfo);
      }
