Winform Forms Closing and opening a new form

Question

1. frmHome frm = new frmHome();
   frm.Show();
   this.Close();

I\'m opening HomeForm from LoginForm. In LoginForm

Answer 1

All you need to do is this it closes the 2 forms without problem. Form1 fin = new Form1(); fin.Close(); this.Visible = false; Form2 win = new Form2(); win.Visible = true;

Answer 2

you can use a boolean (global variable) as exit flag in LoginForm

initialize it to :

exit = true;//in constructor

set it to false before closing:

frmHome frm = new frmHome();
frm.Show();
exit = false;
this.Close();

and in form_closed:

if(exit) Application.Exit();

if a user closes the form with the 'X' button, exit will have the value true, and Application.Exit() will be called.

EDIT:

the above is not working because LoginForm is your main form used by Application.Run(loginForm).

2 suggestions:

With exit flag:

replace

Application.Run(new LoginForm())

by

LoginForm loginFrm = new LoginForm();
loginFrm.Show();
Application.Run();

Without exit flag:

replace in your current code:

frmHome frm = new frmHome();
frm.Show();
this.Close();

by

frmHome frm = new frmHome();
this.Visible = false;
frm.ShowDialog();
this.Close();
