I don't think there is any one specific way to limit a program to a single instance. Some use a registry entry to determine if there is an instance already running, while others use a file or create a system-wide semaphore (see MSDN for CreateSemaphore() win32 api function)
Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.
