Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
TextBox1.Text = Int(Rnd() = 5)
Select Case TextBox1.Text
Case 0
TextBox1.Text = "QXMDH-CRYFM-QFR87-HB783-T7RFQ"
Case 1
TextBox1.Text = "MPEHD-896LO-34214-MNHGT-789LK"
Case 2
TextBox1.Text = "WPD800-58634-01932-46139"
Case 3
TextBox1.Text = "b28e5286-d51b-4d62-b409-bebedoc8a496"
Case 4
TextBox1.Text = "WPD800-59533-72932-66575"
End Select
End Sub
End Class
