Allow only one instance of an application
Is there a way to only allow one instance of an application to run?
The current application is rather large and it takes a moment for the splash page to show. I would like to ignore all attempts to open the application while its loading so that only one instance can be running at a time.

you can get the list of processes which are of the same processname perhaps, if there is more than 1 (1 being current process) found then notify them and exit the app:
Process theProcesses = Process.GetProcessesByName(Process.GetCurrentProcess().ProcessName);
if (theProcesses.Length > 1)
MessageBox.Show("More than 1 instance running");
I'm sure there are other ways as well but hope this gets you started#1; Tue, 04 Sep 2007 09:58:00 GMT

- excellent, glad I could help. Actually edited the post an hour later to make it better, no idea what I was thinking of in the first post but glad that its working for you - the "new and improved" approach at least#3; Tue, 04 Sep 2007 10:00:00 GMT
