WS-SECURITY and calling a webservice

[Karl Prosser]

i am having problems setting the 'credentials' to call a webservice..

i have the WSDL and successfully have created a proxy , and the right code
to call the webservice, other than setting the credentials..

i am using vs 2005 with dotnet framework 2.0

according to their docs the webservice (made by a third party) expects
authentication as below:

A WS-Security Username Token with password in clear text
<wsse:UsernameToken>
…….
</wsse:UsernameToken>

to which i can create a string such as :

<wsse:UsernameToken>
<wsse:Username>thelogin</wsse:Username>
<wsse:Password Type=""wsse:PasswordText"">thepassword</wsse:Password>
</wsse:UsernameToken>

however i don't have a clue how to assign the above to the webservice proxy.
In my searches here (and some articles on codeproject, and msdn).. people use
a class called usernameToken to create the token.. a class i can't find
anywhere, and then adding them through a property of the proxy called
RequestSoapContext
however my proxy doesn't have anything like RequestSoapContext and i can't
find anything in my MSDN library about it either..

this is something that should be simple, but i've spent far too many hours
trying to find out the way to connect these simple dots.

please help.
