In my Program.cs :

static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Login login = new Login();
            Application.Run(login);
            if (login.LoginSuccess == true)
            {
                Application.Run(new Form_Main());
                
            }
        }

After successfully login it opens main form (Form_Main.cs). Now I want to add FormClosing event to Run Login form again after closing Form_Main.

In my Form_Main.cs :

public Form_Main()
        {
            InitializeComponent();
            this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.Form_Main_FormClosing);
        }
private void Form_Main_FormClosing(object sender, FormClosingEventArgs e)
        {
            DialogResult dr = MessageBox.Show("Do you REALLY want to close this app?", "Closing event!", MessageBoxButtons.YesNo);
            if (dr == DialogResult.No)
            
                e.Cancel = true;
            

            else
            {
                e.Cancel = false;
                Application.Run(new Login());            
                  
            }
        }

This is not working. Actually in here I want to close form named Form_Main and want to show another form named Login. Please, help me in FormClosing event to do that.

Thanks in advance.
