Webservice logon by code

Question

Hi,
I created a webservice as a datasource to fetch xml data for a report which is running in an aspx-project. At design time I can use the credential of our own environment but at the customer I have to provide the report with new credentials (account, password) and another url.
Reading in forum/help/manuals I found a lot about logon at databases by code but nothing about logon to webservice. Anybody there who can give me a hint how I can do the trick.

Hi, Jason,
thanks for your fast answer. But I think I didn't describe my problems correctly. So a new try:
I looked at that sample myself before but there isn't an answer to my question. May be I've to precise it:
I have a webservice providing data only. I have several repports (build with CS-XI) with consumer the data. Now I move the reports to the customer environment and have to change the datasources i.e. webservices (url and account) of the reports.
I use the CrystalRteportsViewer in aspx:
<code>
<CR:CrystalReportViewer ID="CrystalReportViewer1" runat="server" AutoDataBind="True"
            Height="1039px" ReportSourceID="CrystalReportSource1" Width="901px" />
        <CR:CrystalReportSource ID="CrystalReportSource1" runat="server">
            <Report FileName="MyReportt.rpt">
            </Report>
        </CR:CrystalReportSource>
</code>
How can I provide the new webservice url and login to the viewer or the MyReport.rpt. (I've seen some sample to provide sql-datasources with new credentials and server but never see anything about webservices).
Regards
