为什么关不了整个程序.Aplication.Exit() 也关不了
该如何解决此问题.急待解决.thanks!

在关闭窗体事件里必须先调用Stop()停止线程，或者你用线程的后台模式
Thread T = new Thread(new ThreadStart(DoDraw));
T.IsBackground=true;
T.Start();

不过最好是start和stop要对应，否则线程一直在…

T.IsBackground=true;
T.Start();

不过最好是start和stop要对应，否则线程一直在运行，会关不掉的

加个Timer控件,
//滚动频率
Timer.Interval=200;
//滚动函数

int txtNum=0;
private void strShow()
{
if ((str.Length - txtNum) > "每次显示字符的个数")
{
label1.Text=str.Substring(txtNum, "每次显示字符的个数"));
txtNum++;
}
else
{
label1.Text=str.Substring(txtNum));
if (txtNum < str.Length)
{
txtNum++;
}
else
{
txtNum = 0;
}
}

}

如果是WebForm，＜MARQUEE＞滚动文字＜/MARQUEE＞
如果是WinForm，隔一秒刷新一次
Label.Text = " " + Label.Text
刷到没有就再从头开始

强人,谢谢你的帮忙,我还有个问题.你帮我写的那段程序,在关闭Form窗体.
为什么关不了整个程序.Aplication.Exit() 也关不了
该如何解决此问题.急待解决.thanks!
