Re: How to limit the number of instances of an application on a server?

Hello all,
I want to know (and to limit) the number of instances of my
application on a server such as Microsoft Server 2003 or 2008. I know
how to look for multiple instances of an app using Joe's code ("How to
avoid multiple instances..
http://www.flounder.com/mvp_tips.htm#Avoiding%20Multiple%20Application%20Instances).
I've implemented Joe's code and tested it the following way :
Using Vista, I log in as user A and start my application. Then,
without closing user A session, I log in as user B and start the same
application. I had hoped that the mutex created when running the 1st
instance of the app as user A would have been shared across all users,
and that - as user B - I would detect that another user is already
running the app. Well, that's not the case. User B ignores another
user has started the app.
How can I solve the problem as given in the title?
Thanks
Phil
