    MessageBox.Show("You answered yes, yes and no.")

End Sub

Unless you have an AddHandler somewhere we can't see, you should declare that your Sub handles the event:

Private Sub MenuPrincipal_Load(sender As Object, e As EventArgs) Handles MyBase.Load
                                                                 ^^^^^^^^^^^^^^^^^^^

You want to use a command when the form opens. Then put the command in Formload , in the example i use Form2 .

Make a Private Sub and then put the name in Load. Don't know what form you are using but changing is not so hard.

Private Sub Form2_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    MenuPrincipal()
End Sub

Private Sub MenuPrincipal()

    MessageBox.Show("You answered yes, yes and no.")

End Sub

But for only a MessageBox make a sub is a bit to much. You can put the MessageBox in Form Load – Bas H Jun 27 '21 at 14:13
