Hello,
If somebody could help me with this one it would be very nice,
the story:
I need to check if a user is online or not at the moment i am doing a user
logoff with javascript but this is not browser proof so it doesn't work all
the time. or doing it with a for() statement that writes every 20 sec the
last unix time to a database, this doesn't work because the for() statements
stops executing the rest of the page so that doesn't work either
the problem:
i can only have one user online for a group, so i have to check if the first
that logges in for a group is online or not, i have a check time of 1 minut
so if a user logges off, a new user can login after a minut.
the reason:
so you think what is the problem put a logoff button on the screen and your
finished, well that would be the answer if i wasn't developing a page for
idiots that destroy the browser window by alt-f4 or the cross instead of the
logoff button.
so hope somebody hacked this problem before.
Thanks in advance
(sorry for the multi post)

You can have function check_timeouts( ) and store_time() that are called
everytime a page is requested.
The store_time function only has to store the current_time.
The check_timeouts function has to compare current_time with stored_time.
If the difference for a user > 60, log the user out.

You can't. All you can do is to figure out who accessed your
site within the last X minutes, hours, or days.
so hope somebody hacked this problem before.
Of course. You must assume that the user is offline, unless you
have reasons to believe otherwise (e.g., a recent access to a page
on your site with that user's credentials).

Hi all,
I have created an ASP script that enters data into an Access Database.
My problem is that I'd like this script to run when the computer is shutdown
or the user logs off.
I think this would be simple enough if the ASP didn't have any user input,
but it does.

Hi All
I have an app that when running if a user selects logoff or shutdown from
the start menu, it will close itself but not logoff windows or shutdown.
From what i have found so far its most likely something ive declared in my
program that is preventing the logoff, i have tried closing and disposing
forms and sql connections, is there anything else i should be looking for ?
Or some way to step through it to find what is causing this

I developed a C# Windows App that requires a user to input their real
name and what they did to the server while they were online.
I am going to launch the app att shutdown via a logoff script.
I want to prevent the computer from logging off or shutting down until
the app is closed.
The best example I have is when you have an unsaved notepad.exe
document open and logoff or shutdown, an End Program dialog pops up

Hi
I have a small .net Windows app that I need to run before the user logs off
the machine. This is a Windows App where a dialog is displayed to the user

I currently have the application running as a logoff script. In other words
I use the Group Policy window to add the executable as a logoff script.
This works fine as long as the app is a console app. But if it's a...

I have a Windows Service that should pop a windows form right before logoff,
for the user to enter some information.
I got things working fairly well except that the user does not get to see
the form before logoff. But I know that it run properly because when I log
back in the form is there and works fine.
So the form opened and run, but windows was already in the "logoff" screen
with no desktop showing, so I missed the form.
Is there any...

Hi,
We have a VB.Net application that is sleeping until it receives a
logoff/shutdown event. We want the application running on Vista and
XP.
When the application receives those events it has to show a message
box, so the user can answer Yes or No, and then let the logoff/
shutdown process continues.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
