dinamic reference to WS

[Javier]

Hello:
I want to create a class that i could use to call a web service without
adding the web reference from Visual Studio. That's because the url to the
..asmx o wsdl document will be given by te user at runtime.
How can i code this? Is it too complex?
Any information, code snippets or links to howtos will be wellcome.
Thanks.
Bye.

It's simple.

In the application that consumes the web service go ahead and make the web
reference as usual. The difference is that you set the "URL Behavior"
property to "Dynamic". Doing so within visual stuidio will automatically
modify the proxy class and the web.config (app.config) file to have a key
with the URL to the web service.

The consumer would then just change the value of the key for the location of
the web service to be loaded at runtime.

Javier,
You should have a url for a "developmen t" version of that web service. Said
that
, you can add the webreference to VisualStudio to that asmx and then at
runtime change the url to the actual asmx.

at runtime...
dim mywebservice = New webreference.my webservice
mywebservice.Ur l = "actualurl.asmx "

Regards,
Alexis

RE: dinamic reference to WS

Hello:
Thanks for te answer, but i have a doubt. When i want to call to one method
of the service, the "developmen t" web service must have the same methods than
the service that will be used at runtime, isn't it?
What i want to say is that i can change the url only if the new url points
to a service with the same interface, same methods and parameters for these
methods but i can't use it to call different web services with differents
method names and different parameters, isn't it?
Thanks for the help.
Bye.

RE: dinamic reference to WS

The web service that is used must have the same methods that your proxy class
has defined begin and end points to and those methods must have the same
signature as your proxy class has defined them as. This means that the web
service could have MORE methods than the proxy class has defined, which is
fine.

If you are worried about the signatures not being the same and can forsee
that this could indeed be the case between your dev and prod environments
then perhaps you should look into deprecation rather than changing the
parameters for already established methods that are in dev and prod.

Does that make sense?

Re: dinamic reference to WS

check uddi.
goto uddi server, locate the websvc, get asmx...
u can ask for whole interface WSDL of a webservice then.
(u need and interface to call the runtime... identified web svc)(u cant
then generate proxy class of course)
