passing parameter to webservice

[H Lim]

Hello,

I am trying to create a very simple form with a company text box and a
contact drop down list. When a company name is change, it calls a web
service to query contacts for that company and populate the drop down. I'm
using VS.NET 03 to do the coding. If anyone has any code sample or
suggestions, please help.

Thanks,
Howard.

Hi Franck,

Thanks for the reply. I did look at the link but could not get it to work.
It's giving me the following error message when I try to run it,

System.NullReferenceException
Object reference not set to an instance of an object.
at
Microsoft.Office.Interop.InfoPath.SemiTrust._DataDOMEventSink_SinkHelper.OnAfterChange(DataDOMEvent
pDataDOMEvent)

the error line is exactly the same as the link below except I replace
DataSourceName with my web service function and param1 with my web service
parameter.

wsDOM.selectSingleNode("/dfs:myFields/dfs:queryFields/s0ataSourceName/s0aram1").text
= thisXDocument.DOM.selectSingleNode("/my:myFields/my:wsParam1").text;

thanks for any other suggestions.

Howard.
