[提问]关于进度条的制作

Question

我从数据库取数据,因为数据量比较大,所以想做个进度条来显示进度,请赐教些思路
对于进度条我只知道设置maxlenght和step的值,呵呵

Answer 1

定个全局变量
bool isProcessEnd = flase控制进度条的函数里写
while( !isProcessEnd )
    process.Value += n;用你取数据的那个线程来改变isProcessEnd的值

Answer 2

1.如果你是WinForm 用一个Timer 控件或New一个线程，来控制进度条件的Value属性2。如果你是WebForm:
Visual C# .NET代码 
using System.Threading;Visual Basic .NET代码 
Imports System.Threading在Page_Load事件里输入： Visual C# .NET代码 
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);Visual Basic .NET代码 
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>点在浏览器
