Your node variable should be an XPathNavigator in InfoPath - here's an MSDN link. https://msdn.microsoft.com/en-us/library/bb509311(v=office.12).aspx - it says it is for IP 2007, but 2010 and 2013 use very similar concepts.

Sending data to text field VB.net - Infopath 2013

Hi all,

I'm currently trying to set a field to 1 when another field is changed. All the tests in VSTA works but when I run infopath it crashes. Any help on this would be amazing!

Here's the code:

Public Sub Incoming_Agent_Login_Changed(ByVal sender As Object, ByVal e As XmlEventArgs)
            Dim node As IHTMLDOMNode
            node = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:Retrieve_Info", NamespaceManager)
            node.text = "1"
        End Sub

And the error:

System.InvalidCastException
Unable to cast object of type 'Microsoft.Office.InfoPath.MsxmlNavigator' to type 'mshtml.IHTMLDOMNode'.
   at NSTAT_v5pt5_0.FormCode.Incoming_Agent_Login_Changed(Object sender, XmlEventArgs e) in C:\Users\wilcojos\AppData\Local\Temp\vsta\1e5cd4420e40498dbbc128d44b5946e0\FormCode.vb:line 46

   at Microsoft.Office.InfoPath.Internal.XmlEventHost.ChangedProxy(DataDOMEvent dataDOMEvent)
   at Microsoft.Office.Interop.InfoPath.SemiTrust._DataDOMEventSink_SinkHelper.OnAfterChange(DataDOMEvent pDataDOMEvent)

Been searching and searching but cannot find an answer. Thank you in advance. :)
