            {

                this.Hide();

                frm.ShowDialog();

if you want to exit application then add this line

 Application.Exit();

to detect if main form is closed, you need to use FormClosingEventHandler and after detecting that main form is closed, then exit application

  this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.yourMainForm_FormClosing);


private void yourMainForm_FormClosing(object sender, FormClosingEventArgs e)
{
  //here you can exit from application 
  Application.Exit();
}

I want to leave the application when the main form is closed
