Thanks! The code seems to be correct. But when i try to run the form i get the following error in infopath.

InfoPath cannot open the selected form because of an error in the form's code.
Index refers beyond end of list

Ah, I see. You're using InfoPath 2003. In that case, this should work:

Dim oActiveContext As IXMLDOMNode

<InfoPathEventHandler(EventType:=InfoPathEventType.OnContextChange)> _
Public Sub FormEvents_OnContextChange(ByVal e As DocContextChangeEvent)
     If (e.Type = "ContextNode" And Not e.IsUndoRedo) Then
          Try
               thisXDocument.SetNamedNodeProperty(oActiveContext, "active", "0")
          Catch
          End Try

          oActiveContext = e.Context
          thisXDocument.SetNamedNodeProperty(oActiveContext, "active", "1")
          Return
     End If
End Sub

This code should do the trick in VB.NET:

Dim oActiveContext As XPathNavigator

Public Sub FormEvents_ContextChanged(ByVal sender As Object, ByVal e As ContextChangedEventArgs)
     If (e.ChangeType = "ContextNode") Then
          Try
               MainDataSource.SetNamedNodeProperty(oActiveContext, "active", "0")
          Catch
          End Try
          oActiveContext = e.Context
          MainDataSource.SetNamedNodeProperty(oActiveContext, "active", "1")
          Return
     End If
End Sub

I believe the sample in the blog post is in jscript -- it looks as if you are using VB.NET. You may want to change the programming language in your form to JScript, then try the sample.

To change the programming language, you'll need to go to Tools/Form Options. Select Programming and click the Remove Code button. Then change the language to JScript.

I have inserted the code and i seem to still be getting errors. I have errors in following places. they are bolded

var oActiveContext = null;

' The following function handler is created by Microsoft Office InfoPath. Do not

' modify the type or number of arguments.

<InfoPathEventHandler(EventType:=InfoPathEventType.OnContextChange)> _

Public Sub OnContextChange(ByVal e As DocContextChangeEvent)

if (eventObj.Type != "ContextNode" || eventObj.IsUndoRedo)return;

Try

{

XDocument.SetNamedNodeProperty(oActiveContext, "active", "0");

}

catch(e){}

oActiveContext = eventObj.Context;

XDocument.SetNamedNodeProperty(oActiveContext, "active", "1");

Return

End If

End Sub

End Class
