tubo12382 2009-10-12 02:34:45

我用的是VS2005 C#语言
我要在打开这个页面后每隔一段时间就在右下角弹出提示.想QQ那样
但是提示内容是重数据库中获得.
我现在用的是两个计时器.可是当我服务器端得计时器激活时就会报错(错误内容):
Sys.WebForms.PageRequestManagerServerErrorException:An unknown error occurred while processing the request on the server。 The status code returned from the server was:500
麻烦告诉帮忙,如果需要源文件请秘QQ:1095676819(JOE)
在线等待高手的到来......
