Sample Code

Method #1

   // m_pList is of type CListCtrl*
   BEGIN_MESSAGE_MAP(CTestView, CView)
        ON_NOTIFY (LVN_GETDISPINFO, IDC_LIST, OnGetDispInfo)
   END_MESSAGE_MAP()

      int CTestView::OnCreate(LPCREATESTRUCT lpCreateStruct)
      {
          // create CListCtrl and columns
      ...
          // insert item; text will be set in LVN_GETDISPINFO
          m_pList->InsertItem (iIndex, LPSTR_TEXTCALLBACK);
      ...
      }

      void CTestView::OnGetDispInfo (NMHDR* pnmhdr, LRESULT* pResult)
      {
          LV_DISPINFO* pdi = (LV_DISPINFO *) pnmhdr;

          // set text for column #1
          if (0 == pdi->item.iSubItem)
              pdi->item.pszText = "1st Column Data";

          // set text for column #3
          else if (2 == pdi->item.iSubItem)

      }
				

Method #2

   int CTestView::OnCreate(LPCREATESTRUCT lpCreateStruct)
   {
       // create CListCtrl and columns
       ...
       // create 3rd column with zero width so it is not visible
       m_pList->InsertColumn (2, "", LVCFMT_LEFT, 0);
       // add items
       ...
       return 0;
   }

   // this function makes the 3rd column appear
   void CTestView::AddColumn()
   {
       LV_COLUMN lvc;

       lvc.mask = LVCF_TEXT | LVCF_WIDTH;
       lvc.cx = 100;
       lvc.pszText = "Column #3";
       // set the text and width of column #3
       m_pList->SetColumn (2, &lvc);
   }
