protected override void OnStylusMove(StylusEventArgs e)
{
if (eraseTester.IsValid)
{
eraseTester.AddPoints(e.GetStylusPoints(this));
}
}
' Collect the StylusPackets as the stylus moves.
Protected Overrides Sub OnStylusMove(ByVal e As StylusEventArgs)
If eraseTester.IsValid Then
eraseTester.AddPoints(e.GetStylusPoints(Me))
End If
End Sub
