Having trouble with implementing a SOAP header

[Friso Wiskerke]

Hi all,

I'm trying to use a webservice which is provided to me by a third party.
There are a number of webmethods that I can call but for each method I have
to supply a SOAP header which contains an identification-token. I've managed
to generate a proxy class using the wsdl.exe tool but the wsdl doesn't have
the SOAP header definition in it (quite frustrating).

I'm trying to enhance the generated class so that I can issue the header to
the webservice but I'm not having much luck.It should look like this
according to the documentation:
<soap:Header>
<AuthToken>ABCDEFGHIJKLMNOP</AuthToken>
</soap:Header>

Does anybody know how I can achieve this in my VB app (C# code samples are
also welcome)?

TIA,
Friso Wiskerke

SoapHeaders are generated as properties of your Proxy object you
created using WSDL. For your AuthToken header, it should be a property
such as

Proxy p = new Proxy();
p.AuthToken = "ABCEFGHIJKLMNOP";

Is this not the fact?

Javier,

I think this would be the case if the soap:Header definition is in the
WSDL... and for some reason it isn't. That's why I'm looking for a way to
add the header myself.

In the example you stated I assume the AuthToken is a string variable and
not a class that inherits from System.Web.Services.Protocols.SoapHeader. I
don't think that this property would result in a soap header when the
message is wrapped into a soap envelope by the proxy object.

Thanks,

You might want to get wsdl file again.

If header is defined you should get that in WSDL file.

here is an example
