Re: Returing Exception Message - ExceptionService.zip (0/1)

Hi,

attached is a zip with 2 source codes.

- ExceptionWebService
Implements a simple webservice with 2 methods; Divide &
DivideWithDetails.
The first 'just tries to execute the divide of the operants comming
in' and the latter checks for a division by 0, if found it produces a
custom message for the SOAP exception thrown.

- ExcpetionServicecClient
Implements a simple WinForm that calls either of the two methods and
shows the results of the call.

Hope this helps,

Marvin Smit.
