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

You need to use a mutex

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.

Just ignore the German language text and have a look at the code.
