Session失效时能否调用方法.

[Kinli]

我用SQL数据库做了个在线用户信息的表,其中字段online记录用户是否在线,用户手动退出时用update修改online为false,我已经做到了,但当Session过期时也是调用修改online为false的这个方法,却无法修改数据库.(我用的判定参数是Session["name"]).请问那位可以帮帮我.急用呀!
我的Do_off事件是这样的
{
Login i = new Login();
i.off(Session["name"].ToString());
Session.Abandon();
} //此事件可修改数据库

但在global.asax的Session_End却不行了.
{
Application.Lock();
Login i = new Login();
i.off(Session["name"].ToString();
Application.UnLock();
}

it should, what database are you using? if you are using Server.MapPath(...) inside Login.off(), it may fail, try to use absolute path

[Kinli]

SQL Server 2000.

[Kinli]

and all the setting is correct.

[saucer]

I cannot tell what's wrong

in Session_End, try to output Session["name"] and other messages (like the Message property of any Exception that could be thrown by Login.off() method) to a file to make sure it is being properly called

[saucer]

should be similar, but


i.off(Session["name"].ToString();

==>

i.off(Session["name"].ToString());

老大眼忒尖!

[Kinli]

这不算,这只是我打错而已.

[saucer]

how did you trigger Session_End? calling Session.Abandon()?

[Rainightwind]

在globa.asax.cs 里面做

protected void Session_End(Object sender, EventArgs e)
{
//// U code
}

[Kinli]

timeout, when the session of user is timeout, i hope it can update the DataBase automatically(call off()).

[Kinli]

To Rainightwind(雨夜):
i done that.

[saucer]

oh, normally it will take 20 minutes, it is easier to just call in logout.aspx:
Session.Abandon()

to trigger Session_End

[Kinli]

i set: timeout="1", and i realized call Session.Abandon() to trigger Session_End.

We know, if we wanna count online user , will write Application["sth"]++ or Application["sth"]-- in Session_Start and Session_End.

The Session is timeout ,the Session_End will be trig automatically.

i just wanna know how come my Session_End can not work when session timeout.
