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,
