這裏的一個應用是UpdateProgress的應用完善。爲了給用戶顯示的效果更好而設計。你可以參看效果：

代碼如下：

{
} protected void Button1_Click(object sender, EventArgs e) { //System.Threading.Thread.Sleep(3000); int j = 0; for (int i = 0; i < 100000000; i++) { j = i+j; } if (TextBox1.Text.Equals(TextBox2.Text)) { Response.Redirect("/login.aspx"); } else { Response.Redirect("/error.aspx"); } }}不過根據研究，http://szhxy.gliet.edu.cn/qxgl/Login.aspx?ReturnUrl=%2fqxgl%2fDefault.aspx使用的方法如下：
他是通過調用htm文件實現圖像顯示的。
將表單代碼去掉替換如下：
<iframe scrolling="no" frameborder="0" marginwidth="0" marginheight="0" src="bar.htm" /></iframe>
可見還需要一個bar.htm。這樣我們就建個：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" ><head> <title>系統提示</title></head><body style="margin: 0px"> <table cellpadding="4" cellspacing="0" style="width: 100%; height: 100%;"> <tr> <td style=" height:26px; text-align: left; background-image: url(tile_back.gif); text-align: left;"> <span style="font-size: 9pt;color: #ffffff"> <strong>系統提示</strong></span></td> </tr> <tr> <td valign="middle" style="height:100%;text-align: center; vertical-align: middle;"> <br /> <br /> <img alt="Waiting..." src="indicator_mozilla_blu.gif" style="vertical-align: middle;border-top-style: none; border-right-style: none; border-left-style: none; border-bottom-style: none" /> <span style="font-size: 9pt">正在處理，請稍後……</span></td> </tr> </table></body></html>測試通過
