Change SOAP Header to add credentials

[vagueante]

Hi,

In a windows app, i have the function and parameter to send to a webservice.
I have a SOAP sample, where i see in the soap header three tags, one with the credentials link, another two with user and password.

I have to put a similar header to my soap, the question is, how can i do it ?

Dim objWebs As New ServiceReference1.CWSDraftClaimDataEntryPortTypeClient
Dim answer As ServiceReference1.draftClaimDataEntryReply
Dim data_ToSend As New ServiceReference1.draftClaimDataEntry
' I put the data in data_ToSend
answer = objWebs.DraftClaimDataEntry(data_ToSend)

What do i need to do, to add the credentials to these?

Is a windows application but don't know if would be best to ask in asp.Net section
