VB

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

ListBox1.Items.Add("First Item")
ListBox1.Items.Add("Second Item")
ListBox1.Items.Add("Third Item")
ListBox1.Items.Add("Fourth Item")
ListBox1.SelectedIndex = 0

Timer1.Interval = 500
Timer1.Start()

End Sub

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

Dim i As Integer
i = ListBox1.SelectedIndex
i = i + 1
If i > ListBox1.Items.Count - 1 Then i = 0
ListBox1.SelectedIndex = i

End Sub
