<script language= "vb " runat= "server ">
sub application_start(S As Object, E As EventArgs)
Application( "counter ")=0
end sub
sub session_start(S As Object, E As EventArgs)
Session( "On_Line ")=False
end sub
</script>



*.aspx 文件
-----------

<script language= "VB " runat= "server ">
function webcounter() as long
if not session( "on_line ") then
application.Lock()
application( "counter ")=application( "counter ")+1
application.UnLock()
session( "on_line ")= true
end if
webcounter=application( "counter ")
end function
</script>

<html>
<head>
<title> count </title>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
</head>
<body>

<h2> 您是第 <font color= "blue "〉 <%= WebCounter %> </font> 位访客! </h2>

这是访问量 不是统计在线人数
你先要拿个东西 纪录登陆了的人员信息 临时表或其他什么东西
