Multiple startup

[KBou]

Hi, I've build an application but it isn't suppose to startup more than once. How do I prevent my application to startup more than once?? Kevin

Possibly the easiest way is to use a mutex. I posted a WPF version here[^], but it's easy enough to apply this to a Forms app.

Deja View - the feeling that you've seen this post before.

Hi, actually none of those "solutions" do what the OP asks. At best they make the second instance die rapidly, but they don't prevent it from starting up. :)

From what I have seen, most are the same, and I use the same thing in my applications too: 1. Create Mutex. 2. Check Mutex, then use IPC (with Remoting) to talk and do what you need with either instance.
