MFC中listCtrl的使用

前一阵子做MFC项目用到了listCtrl控件，今天刚好有空，整理了一下。废话不多说，看代码。
右键菜单：

/*右键菜单*/void CStudentMngDlg::OnNMRClickStudentList(NMHDR *pNMHDR, LRESULT *pResult){    LPNMITEMACTIVATE pNMItemActivate = reinterpret_cast<LPNMITEMACTIVATE>(pNMHDR);    if (pNMItemActivate->iItem != -1)    {        DWORD dwPos = GetMessagePos();        CPoint point(LOWORD(dwPos), HIWORD(dwPos));        CMenu menu;        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;}

/*item切换焦点时(包括用键盘和鼠标切换item时)，状态的一些变化顺序*/void CStudentMngDlg::OnLvnItemchangedStudentList(NMHDR *pNMHDR, LRESULT *pResult){    LPNMLISTVIEW pNMListView = reinterpret_cast<LPNMLISTVIEW>(pNMHDR);    // TODO:  在此添加控件通知处理程序代码    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;}

/*获得listctrl中选中单行的Item信息*/void CStudentMngDlg::OnNMClickStudentList(NMHDR *pNMHDR, LRESULT *pResult){    LPNMITEMACTIVATE pNMItemActivate = reinterpret_cast<LPNMITEMACTIVATE>(pNMHDR);    POSITION pos = m_ctrlStudentList.GetFirstSelectedItemPosition();    if (pos != NULL)    {        int Item = m_ctrlStudentList.GetNextSelectedItem(pos);            CString Sid = m_ctrlStudentList.GetItemText(Item, 1);            CString Sname = m_ctrlStudentList.GetItemText(Item, 2);            MSid = Sid;            MSname = Sname;        else return;    }    *pResult = 0;}

/*右键删除一个*/void CStudentMngDlg::DelOneStudent(){    UpdateData(TRUE);    if (MSid.IsEmpty()) return;               // 图书ISBN号    if (MessageBox("确定要删除学生信息？", "提示",        MB_ICONQUESTION | MB_YESNO) != IDYES)            // 确认提示        return;    try    {        CString strSQL;        _RecordsetPtr pRecordset("ADODB.Recordset");        strSQL.Format("SELECT * FROM student WHERE sid='%s'", MSid);        pRecordset->Open((_bstr_t)strSQL, _variant_t((IDispatch*)m_pConnection, true),            adOpenDynamic, adLockOptimistic, adCmdText); // 打开记录集        if (!pRecordset->BOF) pRecordset->MoveFirst();        if (pRecordset->_EOF) return;                  // 不存在该记录        pRecordset->Delete(adAffectCurrent);           // 删除记录        pRecordset->Update();                          // 更新数据库信息        pRecordset->Close();                           // 关闭记录集        AfxMessageBox("删除学生信息成功。");        OnBnClickedQueryStudent();    }    catch (_com_error &e)    {        AfxMessageBox(e.Description());        return;    }}

/*删除checkbox选中项，即就是批量删除*/void CStudentMngDlg::DelMoreStudent(){    if (MessageBox("确定要批量删除学生信息？", "提示",        MB_ICONQUESTION | MB_YESNO) != IDYES)            // 确认提示        return;    m_ctrlStudentList.SetExtendedStyle(LVS_EX_CHECKBOXES);    CString DMSid[500];    for (int i = 0; i < 500; i++)    {        DMSid[i] = "0";    }    CString Sid;    CString str;    for (int i = 0; i<m_ctrlStudentList.GetItemCount(); i++)    {        if (m_ctrlStudentList.GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED || m_ctrlStudentList.GetCheck(i))        {             Sid = m_ctrlStudentList.GetItemText(i, 1);            DMSid[i]=Sid;        }    }    for (int i = 0; i < m_ctrlStudentList.GetItemCount(); i++)    {           if (DMSid[i]!="0")        {            try            {                CString strSQL;                _RecordsetPtr pRecordset("ADODB.Recordset");                strSQL.Format("SELECT * FROM student WHERE sid='%s'", DMSid[i]);                pRecordset->Open((_bstr_t)strSQL, _variant_t((IDispatch*)m_pConnection, true),                    adOpenDynamic, adLockOptimistic, adCmdText); // 打开记录集                if (!pRecordset->BOF) pRecordset->MoveFirst();                if (pRecordset->_EOF) return;                  // 不存在该记录                pRecordset->Delete(adAffectCurrent);           // 删除记录                pRecordset->Update();                          // 更新数据库信息                pRecordset->Close();                           // 关闭记录集            }            catch (_com_error &e)            {                AfxMessageBox(e.Description());                return;            }        }    }    AfxMessageBox("批量删除学生信息成功。");    OnBnClickedQueryStudent();}

ps：我这里是用CString DMSid[500]的字符串数组存取checkbox选中行的指定列信息，其实也可以用CStringArray类。
