Another way is to have your application either create a text file on
launch, or write something to it.
Then, anytime the app launches it looks for that text file, and if
the file exists or the wording inside of it say something specific,
the app is running.
On quit, either delete the file or write something else to it. The
key here is to catch any type of quit the user uses. If the program
doesn't go thru your quit routine, the file will not be changed on
quit, and will give a false positive on the next launch.
Mine has a text file that on launch, it opens the file for read,
reads from it etc. If the word Windows is in the text, my app is
already open. If it is opening for the first time, it writes
something with the word Windows to the file, signifying that the game
has been launched and is running. On quit, it writes something else
to the file.
