Hello

I am trying to migrate an asp page that uses the soap toolkit to consume a
web service to vb .net. I've had no problem with other web services, just
this particular one -

The service is hosted on my local pc - I add a web reference by browsing to
the WSDL file and it all seems fine until I attempt to invoke the service -
which fails with "There is an error in XML document (1, 430)." in the
exception messge

The method in question returns a boolean status, and the actual 'result' (a
chunk of XML) comes back in one of the arguments to the call - I'm not sure
whether this is good practice or not (I didn't write the service!) or whether
it is causing the problem - but as I said above, it works fine using the soap
toolkit in asp - I've also created my own .net web service that mimics this
(ie. changes the value of one of the arguments) and I am able to succesfully
call that.

I'm a bit stuck as to how to resolve this - if anyone can help here I'd be
very grateful.

Thanks

Simon

Can you post the full exception details? StackTrace, ExceptionType etc?

It doesn't like the value inside your boolean node (should be either
'true' or 'false').

Have you seen what the XML is that's actually travelling across the
wire? If not, maybe try using the Web Service Studio
(http://www.gotdotnet.com/team/tools/web_svc/default.aspx) to have a
look? The Request/Response tab should show you what the XML is that's
being returned from the service.
