Problems calling Dr.Bob's Temperature Converter Web Service

[Stephen Craig]

Hi

I am playing with Web Services and as a starter I am following a tutorial by
Dr.Bob http://www.drbob42.com/examines/examin44.htm

I am using the Web service provided

http://www.eBob42.com/cgi-bin/Celsius42.asmx?wsdl

This all works very nicely except that the remote function calls are
returning values that indicate that I am sending an argument of zero. For
instance, the call to Celsius2Fahrenheit function always returns 32 degrees
no mater what value argument I give it.

I am using the WSDL Import Wizard and BCB 6

Any ideas?

Thanks

Steve

I can explain that: the Celsius42.asmx is hosted on a web server where
the virtual directories are configured as ASP.NET 2.0 - which was
ASP.NET 1.1 in the past.

This is a known issue, described in more detail at

http://www.bobswart.nl/Weblog/Blog.aspx?RootId=5:798

Basically, you need to add a line to RegisterInvokeOptions for the
ioDocument on the just imported type.

In the RegTypes() function, add the following line:

InvRegistry()->RegisterInvokeOptions(__interfaceTypeinfo(Celsius42Soap),
ioDocument);

C++Builder 2007 does a correct import of this web service.

Thanks Bob,
That worked perfectly. Your help is very much appreciated.
This is an area that I have regrettably avoided for the past years and that
was so easy (although you did all the work).
