[IronPython] IronPython and C# not giving the same result

I was able to successfully run that python code under both IronPython 2.0.3 and IronPython 2.6.1 and it produced a list of all top-level applications.  I modified the one line

if rae.Current.Name == 'Untitled - Notepad':

to be

if not rae.Current.Name == '':

just to see what was actually being found.

Note: I'm running Windows XP SP3.

Subject: [IronPython] IronPython and C# not giving the same result

Hi All,

I have tried to transliterate the following C# code to IronPython:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Automation;

namespace ConsoleApplication1
    class Program
        static void Main(string[] args)
            AutomationElement eNode;
            eNode = TreeWalker.ControlViewWalker.GetFirstChild(AutomationElement.RootElement);
            while(eNode != null) {
                if (eNode.Current.Name<http://eNode.Current.Name> == "Untitled - Notepad")
                    AutomationElement ae;
                    ae = TreeWalker.ControlViewWalker.GetFirstChild(eNode);
                    while (ae != null)
                        System.Console.WriteLine("Name: {0}", ae.Current.Name<http://ae.Current.Name>);
                        ae = TreeWalker.ControlViewWalker.GetNextSibling( ae);
                eNode = TreeWalker.ControlViewWalker.GetNextSibling(eNode);

The output of this program looks like:

Name: test1
Name: Untitled - Notepad
Name: Application

This is my IronPython code:

import clr


import System.Windows.Automation as swu

rae = swu.TreeWalker.ControlViewWalker.GetFirstChild( swu.AutomationElement.RootElement )
while rae:
    if rae.Current.Name<http://rae.Current.Name> == 'Untitled - Notepad':
        print '-'*24
        ae = swu.TreeWalker.ControlViewWalker.GetFirstChild( rae )
        while ae:
            print ae.Current.Name<http://ae.Current.Name>
            ae = swu.TreeWalker.ControlViewWalker.GetNextSibling( ae )
        print '-'*24
    rae = swu.TreeWalker.ControlViewWalker.GetNextSibling( rae )

The output of this shows:

I read somewhere that IronPython used to have issues with UI Automation. Is still the case?
