以下未经说明,listctrl默认view 风格为report
-------------------------------------------------------------------------------
1. CListCtrl 风格
       LVS_ICON: 为每个item显示大图标
       LVS_SMALLICON: 为每个item显示小图标
       LVS_LIST: 显示一列带有小图标的item
       LVS_REPORT: 显示item详细资料
直观的理解:windows资源管理器,"查看"标签下的"大图标,小图标,列表,详细资料
--------------------------------------------------------------------------------
2. 设置listctrl 风格及扩展风格
       LONG lStyle;
       lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);//获取当前窗口style
       lStyle &= ~LVS_TYPEMASK; //清除显示方式位
       lStyle |= LVS_REPORT; //设置style
       SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);//设置style
       DWORD dwStyle = m_list.GetExtendedStyle();
       dwStyle |= LVS_EX_FULLROWSELECT;//选中某行使整行高亮(只适用与report风格的listctrl
dwStyle |= LVS_EX_GRIDLINES;//网格线(只适用与report风格的listctrl
dwStyle |= LVS_EX_CHECKBOXES;//item前生成checkbox控件
m_list.SetExtendedStyle(dwStyle); //设置扩展风格
注:listviewstyle请查阅msdn      
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrflistviewstyles.asp
--------------------------------------------------------------------------------
3. 插入数据
       m_list.InsertColumn( 0, "ID", LVCFMT_LEFT, 40 );//插入列
       m_list.InsertColumn( 1, "NAME", LVCFMT_LEFT, 50 );

      //新插入的在上面
       int nRow = m_list.InsertItem(0, "11");// 插入行
       m_list.SetItemText(nRow, 1, "jacky");//设置其它列数据

    //新插入的数据在下面

   int nIndex = m_list.GetItemCount();
    LV_ITEM lvItem;
    lvItem.mask = LVIF_TEXT ;
    lvItem.iItem = nIndex;     //行数
    lvItem.iSubItem = 0;
    lvItem.pszText = (char*)(LPCTSTR)strCount;   //第一列
    //在最后一行插入记录值.
         m_list.InsertItem(&lvItem);
    //插入其它列
    m_list.SetItemText(nIndex,1,strLat);

--------------------------------------------------------------------------------
4. 一直选中item
选中style中的Show selection always,或者在上面第2点中设置LVS_SHOWSELALWAYS
--------------------------------------------------------------------------------
5. 选中和取消选中一行
int nIndex = 0;
//选中
m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED);
//取消选中
     m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);
--------------------------------------------------------------------------------
6. 得到listctrl中所有行的checkbox的状态
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("%d行的checkbox为选中状态"), i);
AfxMessageBox(str);
}
}
--------------------------------------------------------------------------------
7. 得到listctrl中所有选中行的序号
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("选中了第%d"), 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. 得到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);
关于得到设置item的状态,还可以参考msdn文章
       Q173242: Use Masks to Set/Get Item States in ClistCtrl
http://support.microsoft.com/kb/173242/en-us
--------------------------------------------------------------------------------
9. 得到listctrl的所有列的header字符串内容
       LVCOLUMN lvcol;
       char   str[256];
       int   nColNum;
       CString   strColumnName[4];//假如有4
       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中一项可见,即滚动滚动条
m_list.EnsureVisible(i, FALSE);
--------------------------------------------------------------------------------
11. 得到listctrl列数
int nHeadNum = m_list.GetHeaderCtrl()->GetItemCount();
--------------------------------------------------------------------------------
12. 删除所有列
方法一:
         while ( m_list.DeleteColumn (0))
因为你删除了第一列后,后面的列会依次向上移动。
方法二:
       int nColumns = 4;
       for (int i=nColumns-1; i>=0; i--)
           m_list.DeleteColumn (i);
--------------------------------------------------------------------------------
13. 得到单击的listctrl的行列号
添加listctrl控件的NM_CLICK消息相应函数
       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("单击的是第%d行第%d", lvinfo.iItem, lvinfo.iSubItem);
                 AfxMessageBox(strtemp);
           }
           */
         // 方法二:
           /*
           NM_LISTVIEW* pNMListView = (NM_LISTVIEW*)pNMHDR;
           if(pNMListView->iItem != -1)
           {
                 CString strtemp;
                 strtemp.Format("单击的是第%d行第%d",
                                 pNMListView->iItem, pNMListView->iSubItem);
                 AfxMessageBox(strtemp);
           }
           */
           *pResult = 0;
       }
--------------------------------------------------------------------------------
14. 判断是否点击在listctrlcheckbox
添加listctrl控件的NM_CLICK消息相应函数
       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);
           //判断是否点在checkbox
           if(nFlag == LVHT_ONITEMSTATEICON)
           {
                 AfxMessageBox("点在listctrlcheckbox");
           }
           *pResult = 0;
       }
--------------------------------------------------------------------------------
15. 右键点击listctrlitem弹出菜单
添加listctrl控件的NM_RCLICK消息相应函数
       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;
   }

16. item切换焦点时(包括用键盘和鼠标切换item),状态的一些变化顺序
添加listctrl控件的LVN_ITEMCHANGED消息相应函数
       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;
