End Sub 

Remove particular item from a ListBox:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e _
As System.EventArgs) Handles Button1.Click
ListBox1.Items.RemoveAt(4)
'removing an item by specifying it's index
End Sub 

Display selected ListBox item, to a TextBox:
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object,_
ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
TextBox1.Text = ListBox1.SelectedItem
'using the selected item property
End Sub 

Count all items in a ListBox:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e _
As System.EventArgs) Handles Button1.Click
TextBox1.Text = ListBox1.Items.Count
'counting the number of items in the ListBox with the Items.Count
End Sub

Display ListBox item index:
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
