Detect Open Instance and Show It

Question

Hi all!

 

I can check if the application is already running and show a message box that says "The app is already open, please double click on the system tray icon to show it". What I want is that when the user try to open the app again it shows the opened instance. How can I do that?

 

I check if the app is already open by the below codes:

 

string ProsesAdi = Process.GetCurrentProcess().ProcessName;

Process[] sonuc = Process.GetProcessesByName(ProsesAdi);

if (sonuc.Length > 1)

{

MessageBox.Show("Uygulama zaten açik. Sistem tepsisindeki simgeye çift tiklayin.", "Bilgi");

System.Environment.Exit(0);

}

else

{

Application.EnableVisualStyles();

Application.SetCompatibleTextRenderingDefault(false);

Application.Run(new Form1());

}
