上传大文件的进度显示

如题。
C#的喔
在网上找了很多例子、控件，要么不全，要么有问题，弄的好郁闷。
希望能有人能给出个完整的例子，或者完整的控件附带使用示例。
最好能留下QQ方便咨询。
在下先谢谢啦。。

using System.Threading; Response.Write("<div id='mydiv' >");
Response.Write("_");
Response.Write("</div>");
Response.Write("<script>mydiv.innerText = ';</script>");
Response.Write("<script language=javascript>;");
Response.Write("var dots = 0;var dotmax = 10;function ShowWait()");
Response.Write("{var output; output = '正在装载页面';dots++;if(dots>=dotmax)dots=1;");
Response.Write("for(var x = 0;x < dots;x++){output += '·';}mydiv.innerText = output;}");
Response.Write("function StartShowWait(){mydiv.style.visibility = 'visible'; ");
Response.Write("window.setInterval('ShowWait()',1000);}");
Response.Write("function HideWait(){mydiv.style.visibility = 'hidden';");
Response.Write("window.clearInterval();}");
Response.Write("StartShowWait();</script>");
Response.Flush();
Thread.Sleep(10000); 在ShowProgress.aspx窗体的html的中输入：
<script>
HideWait();
</script>

ProgressBar.htm 代码<html xmlns="http://www.w3.org/1999/xhtml" id="mainWindow">
<head>
    <title></title>
    <script language="javascript">
        function SetPorgressBar(pos)
        {
            //设置进度条居中
            var screenHeight = window["mainWindow"].offsetHeight;
            var screenWidth = window["mainWindow"].offsetWidth;
            ProgressBarSide.style.width = Math.round(screenWidth / 2);
            ProgressBarSide.style.left = Math.round(screenWidth / 4);
            ProgressBarSide.style.top = Math.round(screenHeight / 2);
            ProgressBarSide.style.height = "21px";
            ProgressBarSide.style.display = "";

            //设置进度条百分比
            ProgressBar.style.width = pos + "%";
            ProgressText.innerHTML = pos + "%";
        }        //完成后隐藏进度条
        function SetCompleted()
        {
            ProgressBarSide.style.display = "none";
        }
                function SetCompleted1()
        {
            tb1.style.display = "none";
        }

     </script>
</head>
    <body alink="darkgray" style="top:0px; left:0px" bgcolor="darkgray">
    <table id="tb1" width="100%" height="100%" bgcolor="DarkGray">
    <div id="ProgressBarSide" style="position:absolute;height:21x;width:100px;color:Silver;border-width:1px;border-style:Solid;display:none; background-color:White">

这种方法我以前在《ASP.NET2.0高级编程》中见过，清华大学出版，是意大利人写的吧，记得不太清楚了，里面讲过相关的方法，好像是用一个Table来实现的吧
提供一个SQL2000的存储过程，使用非常方便且效率比较高。楼主参考CREATE  procedure [dbo].[sp_PageList]
@sqlstr nvarchar(4000), --查询字符串
@currentpage int, --第N页
@pagesize int --每页行数as
set nocount on
declare @P1 int, --P1是游标的id
@rowcount int
exec sp_cursoropen @P1 output,@sqlstr,@scrollopt=1,@ccopt=1,@rowcount=@rowcount output
select ceiling(1.0*@rowcount/@pagesize) as 总页数--,@rowcount as 总行数,@currentpage as 当前页
set @currentpage=(@currentpage-1)*@pagesize+1
exec sp_cursorfetch @P1,16,@currentpage,@pagesize
exec sp_cursorclose @P1
select @rowcount
set nocount offGO--测试代码
CREATE TABLE tb_test (id int,name varchar(20))
{
insert into tb_test values(1,'111')
insert into tb_test values(2,'222')
insert into tb_test values(3,'333')
insert into tb_test values(4,'444')
insert into tb_test values(5,'555')
}
select * from tb_test--第一个参数是SQL语句，第二个是当前第几页，第三个是几条分页
exec sp_PageList 'select * from tb_test',2,2
