[RESOLVED] To understand button click event.

[zhshqzyc]

I have a button and only one. I saw the code.

Private Sub cmdSomething_Click(Index As Integer)

Select Case Index
    Case 0
        Label1(8).Visible = True
        Label1(7).Visible = True
   Case 1
        Label1(8).Visible = False
        Label1(7).Visible = False

When I click the button the Index is always 0, how can I let the Index is 1?
