The main form is displayed after login verification. How can I keep the login box from running in the background? ? ?

hallo18c

I use vb.net to write a login verification box. When the login password is verified, the main form is entered, but the login box still works in the background. After I hide the login box, I cannot exit the program after closing the main form. Really quit the program after the form is closed! How do I end the login form after entering the main form? ? ?
Thank you in advance, ^ _ ^

You use the main form as the main form

Use the login form as a subform

But I want to start the login form first when starting the program. In this case, the login form is not a sub-form, what should I do?

In this case, first hide the login form.
When closing, make a judgment and close the hidden window to exit the program completely.
I used to do this the first time, but it was not convenient.

I suggest you replace it.

Write a login class with a login method with a return type of bool

public bool log () {
  bool flag = false;
  using (FormLogin f = new FormLogin ()) {
    if (f.ShowDialog () == DialogResult.OK)
    flag = true;
  }
  return flag;
}


Main method in the main program

[STAThread]
static void Main ()
{
Login login = new Login ();
if (login.log ())
Application.Run (new main window ());
}

In the project properties-edit inside -> enable application framework -> program close mode -> when the last form is closed

Me.Hide()'I think this is a bit slow again
            Dim frm As New Form2
            frm.Show()
            Me.Close()

me.Hide();
Main mF = new Main();
mF.ShowDialog();
me.Close();
