Hi Henrik,
It is not my service so I cannot add it.
I ended up writing some .NET code to get it work, if its not some the HTTP Send can't do in VC its something I've use the .NET Task to do anyway. It clearly isn't an issue with VC but moreover with the configuration of the web service, possibly putting some way we can over-ride the variables into VC would help. If we could force the datatype as X then it might work.
Regards,
James
