Question

I just make an application in C#, but something I don’t like. I want to make the application running just one time. Now, if my application is running, when I run the application again, will start another application. I want to make that the application can be running just one time, if you want to run again the application, not create another application, but to start the running application.

Thanks.

Please check this question: Run single instance of an application using Mutex

You are looking for Mutex to check if you application is running. Then find your running application Process and bring it forward.
