m_ListSet.AddString("属性");

放到对话框类的 OnInitDialog()函数中，响应WM_INITDIALOG消息，顺利执行！

具体原因等毕业设计做完之后去研究。

当DoModal被调用后，实际在幕后引起一系列如下的动作：
CDialog::DoModal->CEx06Dialog::OnInitDialog->其它的初始化->CDialog::OnInitDialog->CWnd::UpdateData(FALSE)->CEx06Dialog::DoDataExchange
用户输入数据…
用户单击OK按钮
CEx06Dialog::OnOk->…其它的确认处理…->CDialog::OnOk->CWnd::UpDateData(TURE)->CEx06Dialog::DoDataExchange->CDialog::EndDialog(IDOK)
说明：
1）virtual BOOL OnInitDialog( );
//CDialog::OnInitDialog This member function is called in response to the WM_INITDIALOG message. This message is sent to the dialog box during the Create, CreateIndirect, or DoModal calls, which occur immediately before the dialog box is displayed.
//Override this member function if you need to perform special processing when the dialog box is initialized.

2）BOOL UpdateData( BOOL bSaveAndValidate = TRUE );
//CWnd::UpdateData ：Call this member function to initialize data in a dialog box, or to retrieve and validate dialog data.
//bSaveAndValidate：Flag that indicates whether dialog box is being initialized (FALSE) or data is being retrieved (TRUE).
//By default UpdateData(TRUE) is called in the default CDialog::OnOK handler and UpdateData(FALSE) is called in the default CDialog::OnInitDialog.

3）virtual void DoDataExchange( CDataExchange* pDX );
//CWnd::DoDataExchange Called by the framework to exchange and validate dialog data.
//Never call this function （DoDataExchange） directly. It is called by the UpdateData member function.
//Call UpdateData to initialize a dialog box’s controls or retrieve data from a dialog box.

4）void EndDialog( int nResult );
//CDialog::EndDialog makes the dialog box invisible but does not destroy it.
//Call this member function to terminate a modal dialog box. This member function returns nResu

只在获得选择的时候执行，就需要这样
if( (pNMListView->uNewState & LVIS_SELECTED) && 
!(pNMListview->uOldState & LVIS_SELECTED) )
{
    int nNewItem = pNMListView->iItem;
    ……
}

   报考华中科技大学的考生，2006年计算机学院的硕士学位研究生复试工作即将展开，现将复试有关的工作安排通知如下：

    一、硕士生入学考试考生参加复试分数线基本要求
    1、统考生：总分基本要求360分，政治55分，英语55分，数学一90分，综合考试90分。

Context.RewritePath("AA.Aspx","","OKOK=3333");
Context.Server.Transfer("Test2.Aspx");

这样，就能执行Test2.Aspx，并且QueryString是OKOK=3333。

这个用途特别大。我目前用这个方法来避免使用 Response.Redirect 。
