I have made a WebForm with log ON/OFF off users.
There is a label that shows the total count off users logged on stored in
Application("Us erCount")
It works fine if the users logs out WITH THE LOG-OUT BUTTON, but what if a
user "logs out" by closing with the X-button ?
If I count down the Application("Us erCount") in UNLOAD or DISPOSE I get a
spoky reaction in Application("Us erCount") - it just counts wrong !
What can I do to catch (and count down the total users) that a user "logs
out" by using the X-button ?

You can use a counter in your Global.asax, in the Session_Start and
Session_End events to get a rough idea of how many people are on your site.
There is no good way to get a real-time precise count, however, due to the
stateless nature of the internet.

And mean that your counter only updated when the session timed-out :), again, no better way at this time.

I seems as though my code in Global.asax Session_End is NOT executed.
Sub Session_End(ByV al sender As Object, ByVal e As EventArgs)
' Fires when the session ends
If CType(Session(" UserName"), String) <> "" OrElse Not
(Session("UserN ame") Is Nothing) Then
Application("Al lUsers") = CType(Applicati on("AllUsers") , Integer) - 1
End If
End Sub
IS the sub Session_End REALLY fired when the user closes using the
X-button - how can I make shure ?
(a break-point somewhere in the Session_End will NOT do it !)
Should I addhandler or what ?

If I just do myGridView.Rows.Count, then it just returns me the total number

But if I have, 10 pages (10 records per page) and 98 records total,
Rows.Count will return me 10 on the first 9 pages, and 8, on the last page.
