Not entirely sure what you are trying to achieve, but from what I can gather you want to add "(A)", "(B)" and so on to the combobox, but you want the combobox's index to start from numbers that you choose.Not sure if you can do that as it's like a primary key and there to only keep things in order.With that being said, you could use a Dictionary to achieve this to some extent.Here is how I would do it, think of the key as the index value
Public Class Form1
Dim items As New Dictionary(Of Integer, String) ''your items Dictinary List
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
''add items here.
items.Add(83, "(A)")
items.Add(84, "(B)")
items.Add(99, "(C)")
items.Add(45, "(D)")
items.Add(22, "(E)")
items.Add(10, "(F)")
For Each item As String In items.Keys ''add the items key or value to the list.
ComboBox1.Items.Add(item)
Next
End Sub
Private Sub ComboBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ComboBox1.SelectedIndexChanged
Label1.Text = items.Values(ComboBox1.SelectedIndex) ''we can select the value or key based on the items key or value that is allocated to it depending on which way you do it
End Sub
End Class
So now if you select an item from the combobox, the label will display the 'key' of the value that is selected.
