WTL 学习四 动态生成CListViewCtrl 并应用tinyxml加载远程Xml数据

本机站点：http://localhost:2000/Default6.aspx 代码内容

    protected void Page_Load(object sender, EventArgs e)    {       string strSessionXml = "<?xml version=\"1.0\" encoding=\"gb2312\"?><root><item id=\"1\" name=\"风云\" address=\"192.168.1.101\" datetime=\"2012/5/15 16:24:35\" state=\"在线\"></item><item id=\"2\" name=\"雄霸\" address=\"192.168.1.102\" datetime=\"2012/5/15 16:24:35\" state=\"离线\"></item></root>";        Response.Write(strSessionXml);    }

生成 的Xml为

<?xml version="1.0" encoding="gb2312"?><root><item id="1" name="风云" address="192.168.1.101" datetime="2012/5/15 16:24:35" state="在线"></item><item id="2" name="雄霸" address="192.168.1.102" datetime="2012/5/15 16:24:35" state="离线"></item></root>

TestDialog.cpp   很多字符转换，也不知道应用的对不对，先来实现功能吧，后续慢慢优化
