Detect Open Instance and Show It

Pisi Can

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());

}

Create below object in App class
Mutex mutex;
Write below code in App class constructor
mutex = new Mutex(true, "Test", out isnew);
if (!isnew)
{
CustomMessageBox.Show("Application ALREADY RUNNING.","Test",MessageBoxButton.OK);
Environment.Exit(0);
}
if you have Winform Application then put it in Main method
