Due to some bugs in Visual Studio, you need to use the command line tool (wsdl.exe) to generate the proxy classes rather than the IDE (there's a brief note on this at the bottom of http://www.loc.gov/z3950/agency/zing/srw/xml-files.html). Also note that you must list all the URL to the schema and WSDL files on the command line. E.g. wsdl.exe http://www.loc.gov/z3950/agency/zing/srw/srw-bindings.wsdl http://www.loc.gov/z3950/agency/zing/srw/srw-ports.wsdl http://www.loc.gov/z3950/agency/zing/srw/srw-types.xsd Matthew > -----Original Message----- > From: Z39.50 Next-Generation Initiative [mailto:[log in to unmask]] > On Behalf Of 10.0.0.1 > Sent: 01 April 2004 07:49 > To: [log in to unmask] > Subject: srw question > > hello > I try to connect to your site with vs.net to > http://www.loc.gov/z3950/agency/zing/srw/srw-ports.wsdl > <http://www.loc.gov/z3950/agency/zing/srw/srw-ports.wsdl> > and it should generate a proxy class (class with all the > methods)and it is fails do you have any idea why i need to do? > thank you > dov > >
