multi vars?

Why don't you simply call that click event and pass Index (if you do have control array) ?
Here is a quick sample:

Private Sub Command1_Click()
    WebBrowser1_DownloadBegin 0
End Sub
 
Private Sub WebBrowser1_DownloadBegin(Index As Integer)
    Select Case Index
        Case 0, 1
            MsgBox "Start downloading... Please wait."
    End Select
End Sub
