Opening Windows Applications

[Never4Get]

I've created a form with several buttons. One of these buttons opens a Windows Application. This application should however open only once, so when the user presses the button again, an error message should appear. Is there a possibility to know weather or not the application is already running so I can perform a test on that.

Please let me know...

if you press ctrl alt and delete it will come up with a list of everything that is running on your computer

I think you could make this work for you:

API: Find out if an application is currently running
