Stopping multiple instances of an application

Hi,

Is there any way I can stop an application being run twice - ie if it's already running just bring up the current instance & if not start a new instance?

I'm using VS2005

Are you using VB or C#? Because if you're using VB, it's one of the project properties. If you're using C#, it's a different matter altogether. We did this using named pipes.

Hi,

I have selected "single instance application" in the properties & it's doing what it's supposed to - ie only one instance running.

However I also want to be able to run a modified version of the same application. But it won't let me - it appears to think the 2 applications are the same one.

What is it that defines the application? I've changed the assembly name, but no luck
