Disallow multiple copies of app

[Rob Oldfield]

I have an VB windows form app which I need users to be able to run once. If
they have a copy running on one machine on a network, then I have to stop
them logging on to a second machine and running it from there. Users also
have access to the app through terminal services, so this also includes the
possibility of users starting a second TS session.

At present, I'm doing this by writing the users status to SQL when they
start/exit the app, but I've found it a little bit clumsy. Does anyone have
a nice way of doing it?

Hi Rob,

I think with logging that to your SQL server you have found a great
solutinon for that problem.

As far as I know does the active directory not know what is running on a
client in the network, and that had been in my opinion the only other
posibility.

Just my thought,

Cor

Thanks for that Cor. I thought of figured that there may not be a better
way of doing it. Think you're right that AD won't identify running apps.
