way to check if program is already running

TM
Is there any way to check if another instance of my program is running if a
user executes it ?

I would like to warn the user if the program is already running to prevent
multiple instances.

Thanks

Hi Bob,

Ken did give a link to a answer from Tom using managed code.

When you give a link to a solution using an API, than you have to tell in my
opinion what is not good on the managed code soluction.

Hello, I would like to prevent my perl program to be executed several times simultaneously (if the program is already running, I would like to display a message like "another instance of this program is already running, please try again in a couple of minutes). For doing this, I guess I have to check the running processes... but I don't know how to do that and how I can identify my program in the running processes.
