Hi Xianzhong,
I reall enjoy your article and code sample.
The reason that "Undefined" appears is because you have () for OnSuccess when you call Web service.

SumServiceSpace.SumService.GetSum(
eval(form1.TextBoxA.value),
eval(form1.TextBoxB.value),
OnSuccess());

Message will go away if you remove () after OnSuccess.
