Our vender provided us a web service:

2> authetication further nested into:

---------------------------------------------------------------
I am trying to pass some parameters to this web service from test.aspx webform....
The out it is expecting is something like this

<authentication>
<principal>test</principal>
<creditial>test123</credential>
<authetication>
<parameters>
<name>text<name>
<value>testtext</value>
</parameters>
<name>numeric</name>
<value>56</value>
</parameters>

Now I added a web referece to this webservice

dim xref as new xyztext.

if I do sref.postevent
it is expecting 1st parameter as authetication as xyztest.authentication

same for parameters..

parameter() as xyztest.nameparameterValuePair

------------------------------
I am not sure how to pass these parameters to web service.. to trigger a webservice..
I would appreciate if someone could help me with this....
