WebServiceConnection for Repeating Rows

[Janko]

Hi guys,
its me again

Sorry to post quite alot questions here, but unfortunatly the information
source at this moment for Infopath 2007 is a bit low....

Anyway
I do have another nice little problem:

I have a repeating table which is filled throuch a Web Service DB connection
with data.
Now I wanna save back to the database the changes i made for each row.

I wrote VB.NET code which calls my created webservice.
Here is the code:

Public Sub CRTL11_8_Clicked(ByVal sender as Object, ByVal e as
ClickedEventArgs)

Dim wsCon as WebServiceConnection = _
DirectCast(Me.DataConnections("Versenden"), WebServiceConnection)

wsCon.Execute()
End Sub

This code works fine so far but only for the first row.
I do know that I can call each row by using the e Variable.

I tried as well the the expanded version of Execute

like:
wsCon.Execute(xpnInput, xpnOutput, xpnError)

where
Dim xpnInput as XPathNavigator = e.Source.SelectSingleNode(fields,
NamespaceManager)
Dim xpnOutput, xpnError as XPathNavigator = inputDoc.CreateNavigator()

But it does not work.

How can I call the values form each row to pass the values to the parameters
which are necessary to proceed the update command within the SQL Server 2005.

I use InfoPath 2007 with direct connection (Web Service) to the SQL Server
2005

Any help is more then appreciated

Regards
Janko

Hi Update on my Problem

I wrote the following code:

Public Sub CTRL11_8_Clicked(ByVal sender As Object, ByVal e As
ClickedEventArgs)

Dim wsCon As WebServiceConnection = _
DirectCast(Me.DataConnections("Versenden"),
WebServiceConnection)

Dim inputDoc As XmlDocument = New XmlDocument()
Dim outputDoc As XmlDocument = New XmlDocument()
Dim errorDoc As XmlDocument = New XmlDocument()

Dim fieldsID As String = "ns1:IDT"
Dim xpnInID As XPathNavigator =
e.Source.SelectSingleNode(fieldsID, NamespaceManager)

Dim fieldstxt As String = "ns1:Text"
Dim xpnIntxt As XPathNavigator =
e.Source.SelectSingleNode(fieldstxt, NamespaceManager)

inputDoc.LoadXml("<?xml version=" & """1.0""" & " encoding=" &
"""utf-8""" & _
" ?><myFields><IDT>" & xpnInID.InnerXml &
"</IDT><Text>" & xpnIntxt.InnerXml & _
"</Text></myFields>")

Dim xpnInput As XPathNavigator = inputDoc.CreateNavigator()
Dim xpnOutput As XPathNavigator = outputDoc.CreateNavigator()
Dim xpnError As XPathNavigator = errorDoc.CreateNavigator()

wsCon.Execute(xpnInput, xpnOutput, xpnError)

End Sub

the XPathNavigator xpnInput receives the values from the changed row but i
receive an error when the method execute is getting called with the following
error message:

System.Net.WebException
Exception from HRESULT: 0x8004304D
at
Microsoft.Office.Infopath.Internal.MomExceptionHelper.ExecuteDataConnectionAction(OMCall d)

and so on....
