How can I tell if my program is already running in memory? Code is
appreciated.

Thanks
 
Check you System.Diagnostics.Processes collection to see if a process with
the same name is running

But won't work if there are 2 or more apps with the same name (but
different apps) running on the machine. I know, that's a rare case, but
it can happen for simple app names like "Calc" or something like that.

For alternatives, see other replies.

But you can start calc twice!

But my own "Calc" replacement only allows one instance and it should
still run if Windows' Calc is running.

Was it really "necessary" to write your own Calc app? Cmon now. =)
