Only one copy of my program running

[Griffyn]

Hi all,

I get the feeling this one's been asked before, and recently, but I couldn't find it anywhere.

How do I prevent my program from being executed if it's already running?

Obviously, the second instance will check to see if the same process is running, and then terminate immediately if so, but I don't know how to check. Can anyone help? Many thanks.

Doh. Should have kept looking for 5 more minutes. Found this:

which gives me the answer. I'll post back if this doesn't work for some reason.

You can download ABF components from

http://www.abf-dev.com/

and there you shall find:
TabfOneInstance allows user to create applications that must have only one running copy at the same time. Simple drop TabfOneInstance onto any form of the project to catch the second program run.

(it's free)
