Question

What I want to do here is to increase the number on a label for next combobox item selected

Tom                 1
Jane                2
Mary                3
John                4
etc..               etc..
etc..               etc..
etc..               etc..

Answer 1

On selected index changed event set the value of the label as desired text.
Have alook on the code below:

 Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged

Select Case comboBox1.SelectedItem.ToString()
Case "Tom"
   label1.text="1"
Case "Jane"
    label1.text="2"

' And so on
End Select

 End Sub
