Question

Basically I have a Login window which should close once the user logs in and show another window, for now I’ve just hid it(Form.Hide()) however I do not wish to take unnescesary system resources and I don’t need the login window after I already logged in.

this is the code snippet where I perform the operation:

MainWindow w = new MainWindow();
        TimeRegisterApI.Instance.Windows.Add(w.Text,w);
        TimeRegisterApI.Instance.Windows[w.Text].Show();
        this.Dispose();

Windows is a dictionary that stores references of forms with their title as the key.
TimeRegisterApi is a singleton.
Basically what happens is that my application exits after I login instead of just disposing the login window, when I want it to dispose(close and go to the garbage collector.)

I know that having the title as key might cause duplicate key entries but in my current design it’s no problem.

Answer 1

ok I fixed the problem, basically what happens is that when the window that is run from program.cs at application.run(window) gets disposed it closes the program because it’s the main window, I think it would be possible to do an e.cancel on the dispose event of this window, however I solved the problem by running the window in a new application.run like this:

from program.cs, relevant lines

 static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new LoginWindow());
        start();
    }

 public static void start()
    {
        if (TimeRegisterApI.isLoggedIn())
        {
            MainWindow w = new MainWindow();


            Application.Run(w);
        }
    }
