The following code example displays information about items in a list that have been changed after a specified date. The example uses an XmlDocument object to create XmlNode objects for parameters.

This example requires that a using (Visual C#) or Imports (Visual Basic) directive be included for the System.Xml namespace.

Dim listService As New Web_Reference_Folder.Lists()
listService.Credentials = System.Net.CredentialCache.DefaultCredentials

Dim xmlDoc = New System.Xml.XmlDocument()

Dim ndViewFields As XmlNode = 
    xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "")
Dim ndContains As XmlNode = 
    xmlDoc.CreateNode(XmlNodeType.Element, "Contains", "")

ndViewFields.InnerXml = "<FieldRef Name='Field1'/>" + _
    "<FieldRef Name='Field2'/><FieldRef Name='Field3' />"
ndContains.InnerXml = "<FieldRef Name='Field'/>" + _
    "<Value Type='Number'>Number</Value>"

Try

    Dim ndListChanges As XmlNode = 
            listService.GetListItemChanges("List_Name", _
        ndViewFields, "2003-06-18T00:00:00Z", ndContains)

    MessageBox.Show(ndListChanges.OuterXml)

    Catch ex As System.Web.Services.Protocols.SoapException

        MessageBox.Show("Message:" + ControlChars.Lf + ex.Message + 
                ControlChars.Lf + _
            "Detail:" + ControlChars.Lf + ex.Detail.InnerText + 
                ControlChars.Lf + _
            "StackTrace:" + ControlChars.Lf + ex.StackTrace)

End Try
