How do I override default mouse wheel settings

[Reverend Jim]

I have a NumericUpDown control that I want to allow the user to change with the mouse scroll wheel. The problem is that even with the following code

Private Sub numSeries_MouseWheel(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles numSeries.MouseWheel
    If e.Delta > 0 Then
        numSeries.Value += 1
    Else
        If numSeries.Value > 0 Then
            numSeries.Value -= 1
        End If
    End If
End Sub

The value in the control changes based on Windows mouse settings. Specifically, my mouse is set (in Control Panel) to scroll two lines with each wheel "tic". The above code therefore changes my value by +3 or -3 because (apparently) the event is being handled at two different levels. Is there some way to tell VB that I want to handle this event all by myself and ignore the default action?
