In a C# Windows Forms application I want to detect if another instance of the application is already running.
If so, activate the main form of the running instance and exit this instance.
What is the best way to achieve this?

I was wondering if anyone knew of any limitations to using Windows XP as a File and SQL server. I am asking because one of the applications we sell, requires the customer to setup a server for filesharing and as a SQL Server.

Another quicker way is:
