如下未經說明，listctrl默認view 風格爲report
-------------------------------------------------------------------------------
1. CListCtrl 風格
       LVS_ICON: 爲每一個item顯示大圖標
       LVS_SMALLICON: 爲每一個item顯示小圖標
       LVS_LIST: 顯示一列帶有小圖標的item
       LVS_REPORT: 顯示item詳細資料
直觀的理解：windows資源管理器，"查看"標籤下的"大圖標，小圖標，列表，詳細資料
--------------------------------------------------------------------------------
2. 設置listctrl 風格及擴展風格
       LONG lStyle;
       lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);//獲取當前窗口style
       lStyle &= ~LVS_TYPEMASK; //清除顯示方式位
       lStyle |= LVS_REPORT; //設置style
       SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);//設置style
       DWORD dwStyle = m_list.GetExtendedStyle();
       dwStyle |= LVS_EX_FULLROWSELECT;//選中某行使整行高亮（只適用與report風格的listctrl）
dwStyle |= LVS_EX_GRIDLINES;//網格線（只適用與report風格的listctrl）
dwStyle |= LVS_EX_CHECKBOXES;//item前生成checkbox控件
m_list.SetExtendedStyle(dwStyle); //設置擴展風格
注：listview的style請查閱msdn
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrflistviewstyles.asp
--------------------------------------------------------------------------------
3. 插入數據
       m_list.InsertColumn( 0, "ID", LVCFMT_LEFT, 40 );//插入列
       m_list.InsertColumn( 1, "NAME", LVCFMT_LEFT, 50 ); php

      //新插入的在上面
       int nRow = m_list.InsertItem(0, "11");// 插入行
       m_list.SetItemText(nRow, 1, "jacky");//設置其它列數據 html

//新插入的數據在下面 shell

   int nIndex = m_list.GetItemCount();
    LV_ITEM lvItem;
    lvItem.mask = LVIF_TEXT ;
    lvItem.iItem = nIndex;     //行數
    lvItem.iSubItem = 0;
    lvItem.pszText = (char*)(LPCTSTR)strCount;   //第一列
    //在最後一行插入記錄值.
         m_list.InsertItem(&lvItem);
    //插入其它列
    m_list.SetItemText(nIndex,1,strLat);
--------------------------------------------------------------------------------
4. 一直選中item
選中style中的Show selection always，或者在上面第2點中設置LVS_SHOWSELALWAYS
--------------------------------------------------------------------------------
5. 選中和取消選中一行
int nIndex = 0;
//選中
m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED);
//取消選中
     m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);
--------------------------------------------------------------------------------
6. 獲得listctrl中全部行的checkbox的狀態
m_list.SetExtendedStyle(LVS_EX_CHECKBOXES);
CString str;
for(int i=0; i<m_list.GetItemCount(); i++)
{
if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED || m_list.GetCheck(i))
{
str.Format(_T("第%d行的checkbox爲選中狀態"), i);
AfxMessageBox(str);
}
}
--------------------------------------------------------------------------------
7. 獲得listctrl中全部選中行的序號
方法一：
       CString str;
       for(int i=0; i<m_list.GetItemCount(); i++)
       {
           if( m_list.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED )
           {
                 str.Format(_T("選中了第%d行"), i);
                 AfxMessageBox(str);
           }
       }
方法二：
       POSITION pos = m_list.GetFirstSelectedItemPosition();
       if (pos == NULL)
           TRACE0("No items were selected!\n");
       Else
       {
           while (pos)
           {
                 int nItem = m_list.GetNextSelectedItem(pos);
                 TRACE1("Item %d was selected!\n", nItem);
                 // you could do your own processing on nItem here
           }
       }
--------------------------------------------------------------------------------
8. 獲得item的信息
       TCHAR szBuf[1024];
       LVITEM lvi;
       lvi.iItem = nItemIndex;
       lvi.iSubItem = 0;
       lvi.mask = LVIF_TEXT;
       lvi.pszText = szBuf;
       lvi.cchTextMax = 1024;
       m_list.GetItem(&lvi);
關於獲得設置item的狀態，還能夠參考msdn文章
       Q173242: Use Masks to Set/Get Item States in ClistCtrl
http://support.microsoft.com/kb/173242/en-us
--------------------------------------------------------------------------------
9. 獲得listctrl的全部列的header字符串內容
       LVCOLUMN lvcol;
       char   str[256];
       int   nColNum;
       CString   strColumnName[4];//假若有4列
       nColNum = 0;
       lvcol.mask = LVCF_TEXT;
       lvcol.pszText = str;
       lvcol.cchTextMax = 256;
       while(m_list.GetColumn(nColNum, &lvcol))
       {
           strColumnName[nColNum] = lvcol.pszText;
           nColNum++;
       }
--------------------------------------------------------------------------------
10. 使listctrl中一項可見，即滾動滾動條
m_list.EnsureVisible(i, FALSE);
--------------------------------------------------------------------------------
11. 獲得listctrl列數
int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();
--------------------------------------------------------------------------------
12. 刪除全部列
方法一：
         while ( m_list.DeleteColumn (0))
由於你刪除了第一列後，後面的列會依次向上移動。
方法二：
       int nColumns = 4;
       for (int i=nColumns-1; i>=0; i--)
           m_list.DeleteColumn (i);
--------------------------------------------------------------------------------
13. 獲得單擊的listctrl的行列號
添加listctrl控件的NM_CLICK消息相應函數
       void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
       {
           // 方法一：
           /*
           DWORD dwPos = GetMessagePos();
           CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
           m_list.ScreenToClient(&point);
           LVHITTESTINFO lvinfo;
           lvinfo.pt = point;
           lvinfo.flags = LVHT_ABOVE;
           int nItem = m_list.SubItemHitTest(&lvinfo);
           if(nItem != -1)
           {
                 CString strtemp;
                 strtemp.Format("單擊的是第%d行第%d列", lvinfo.iItem, lvinfo.iSubItem);
                 AfxMessageBox(strtemp);
           }
           */
         // 方法二:
           /*
           NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
           if(pNMListView->iItem != -1)
           {
                 CString strtemp;
                 strtemp.Format("單擊的是第%d行第%d列",
                                 pNMListView->iItem, pNMListView->iSubItem);
                 AfxMessageBox(strtemp);
           }
           */
           *pResult = 0;
       }
--------------------------------------------------------------------------------
14. 判斷是否點擊在listctrl的checkbox上
添加listctrl控件的NM_CLICK消息相應函數
       void CTest6Dlg::OnClickList1(NMHDR* pNMHDR, LRESULT* pResult)
{
DWORD dwPos = GetMessagePos();
           CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
           m_list.ScreenToClient(&point);
           LVHITTESTINFO lvinfo;
           lvinfo.pt = point;
           lvinfo.flags = LVHT_ABOVE;
           UINT nFlag;
           int nItem = m_list.HitTest(point, &nFlag);
           //判斷是否點在checkbox上
           if(nFlag == LVHT_ONITEMSTATEICON)
           {
                 AfxMessageBox("點在listctrl的checkbox上");
           }
           *pResult = 0;
       }
--------------------------------------------------------------------------------
15. 右鍵點擊listctrl的item彈出菜單
添加listctrl控件的NM_RCLICK消息相應函數
       void CTest6Dlg::OnRclickList1(NMHDR* pNMHDR, LRESULT* pResult)
       {
           NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
           if(pNMListView->iItem != -1)
           {
                 DWORD dwPos = GetMessagePos();
                 CPoint point( LOWORD(dwPos), HIWORD(dwPos) );
                 CMenu menu;
                 VERIFY( menu.LoadMenu( IDR_MENU1 ) );
                 CMenu* popup = menu.GetSubMenu(0);
                 ASSERT( popup != NULL );
               popup->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this );
           }
           *pResult = 0;
   } windows

16. item切換焦點時 (包括用鍵盤和鼠標切換 item時 )，狀態的一些變化順序
添加 listctrl控件的 LVN_ITEMCHANGED消息相應函數
       void CTest6Dlg::OnItemchangedList1(NMHDR* pNMHDR, LRESULT* pResult)
       {
           NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
           // TODO: Add your control notification handler code here
           CString sTemp;
           if((pNMListView->uOldState & LVIS_FOCUSED) == LVIS_FOCUSED && (pNMListView->uNewState & LVIS_FOCUSED) == 0)
           {
                 sTemp.Format("%d losted focus",pNMListView->iItem);
           }
           else if((pNMListView->uOldState & LVIS_FOCUSED) == 0 &&
               (pNMListView->uNewState & LVIS_FOCUSED) == LVIS_FOCUSED)
           {
                 sTemp.Format("%d got focus",pNMListView->iItem);
           }
           if((pNMListView->uOldState & LVIS_SELECTED) == LVIS_SELECTED &&
             (pNMListView->uNewState & LVIS_SELECTED) == 0)
           {
                 sTemp.Format("%d losted selected",pNMListView->iItem);
           }
else if((pNMListView->uOldState & LVIS_SELECTED) == 0 && (pNMListView->uNewState & LVIS_SELECTED) == LVIS_SELECTED)
           {
sTemp.Format("%d got selected",pNMListView->iItem);
}
*pResult = 0;
