How to make a 'Don't show again form in vb.net'

'***Edit better to use Reg Keys!
' make bools = true, instead of "not" because they might already be true and will make them false by doing that.


'This will load [loginFORM.vb] before the main form unless you check the checkbox in [loginFORM.vb] telling it not too ever again
'This has no flicker of the main form, it is very smooth.


'--------------In form 1-----------------

'► Create a Boolean setting and make sure it's initial value is false which is automatic.
'► Make form1 property setting 'ShowInTaskBar' to 'FALSE' and form1 property setting 'WindowState' to 'MINIMIZED'
'► Make another form to be the login and create checkbox on that form, in my example I call it [loginFORM.vb]



'► ---------------------Put the follow somewhere inside the code of [form1.vb]--------------------------

Private Sub Form1_Shown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shown

        If Not My.Settings.showlogin Then
            Login.Show()
            Me.Hide()
        End If
    End Sub
