  <p><strong>Update:</strong></p>
  
  <p>At first I open my login form as bellow:</p>
  
  <pre><code>Application.Run(new frmLogin());
  </code></pre>
  
  <p>Then I open my main form from the login form as bellow:</p>
  
  <pre><code>this.Hide();
  frmMain frmMain = new frmMain();
  frmMain.Show();
  </code></pre>
