How can i fix this with ListBox issue?

this is my code:

Private Sub StartToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As     System.EventArgs) Handles StartToolStripMenuItem.Click
    Video1.Start()
    Video1.Interval = 4000
    ToolStripStatusLabel2.Text = "Browsing"
End Sub

Private Sub Video1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Video1.Tick
    ToolStripStatusLabel4.Text += 1
    ListBox1.SelectedIndex = rnd.Next(0, ListBox1.Items.Count - 1)
    WebBrowser1.Navigate(ListBox1.SelectedItem)
End Sub

Problem is lets say the timer interval is set to 4 secods (4000). i want my application to navigate to each item in my ListBox in order: website1, website 2, website3, ect. But instead its doing this: website 5, website2, website 8, website 1. Its navigating to randome website.

The reason it's random appears to be because you are calling the random number generator and selecting that item from the list box:

rnd.Next(0, ListBox1.Items.Count - 1)

Instead you should allocate a variable which stores which index you are currently on. Increment this each time the timer ticks.

Private currentIndex As Integer = 0

Private Sub Video1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs)     Handles Video1.Tick
    ToolStripStatusLabel4.Text += 1
    currentIndex += 1
    ListBox1.SelectedIndex = currentIndex
    WebBrowser1.Navigate(ListBox1.SelectedItem)
End Sub
