I create 2 forms for a windows form application:  (coding attached)
1) FrmLogin : the login form which show when the application start
2) FrmMain : the main form which show if user input "User" in a textbox in
login form, else
             it won't show.

Problem: If I input "user" in login form to go to the main form, main form is
shown, but
when I close the main form (FrmMain), the application doesn't terminate...

How to manage application termination for multiple forms project which show
only 1 form
at a time? Thanks for replying...

Public Class FrmLogin

   Private Sub btnOK_Click(...)...
       If txtUser.Text = "User" Then
           Me.Hide()
           FrmMain.Show()
       Else
           Me.Close()
       End If
   End Sub

End Class
