Turning off user specific PC access based on stimulus?

[Brad Markisohn]

Is there a way to log a non-administrative user off a PC or prevent them
from accessing the PC based on some external test? We can assume that the
OS is either Win 2k or Win XP.

TIA
Brad

Hi

I agree with Nikolay's suggestion.
Also to logoff the current user, we can use the ExitWindowsEx API, if you
wants to logoff another user, e.g. you have the admin right on an terminal
server., we can use the WTSLogoffSession API.

If you wants to prevent certain user from logon, I think it would be better
to disable his account even delete the account.

If you still have any concern please feel free to post here.

Peter and Nikolay,

Thank you for the responses, however I don't think that I've explained my
problem very clearly. What I'd like to do is programatically log off or
disable a user based on some critieria. Here's an example of what I'd like
to do: My son's bed time is 10:00 PM. At 10:00 PM he should log off of the
computer and go to bed. I'd like to run an application, possibly a windows
service, that keeps track of time then logs him off when it's time to go to
bed. This doesn't have any other impact on the current user other than to
log them off. Is this something that I can do via the ExitWindows API?

Thanks again.

Brad

Hi

I agree with Nikolay's suggestion, because ExitWindowsEx API is used to log
off current user(The caller).

For detailed information, you may take a look at the MSDN.

The ExitWindowsEx function returns as soon as it has initiated the shutdown
process. The shutdown or logoff then proceeds asynchronously. The function
is designed to stop all processes in the caller's logon session. Therefore,
if you are not the interactive user, the function can succeed without
actually shutting down the computer.

Also here is link about WTSLogoffSession in vb6, I think it will be
migrated to vb.net easier.
BTW: Long in vb6 means 32bit while in vb.net long means 64bit. So in the
vb.net you can use int32 to replace the long in vb6.
