[IronPython] What's wrong with IronPython (UIAutomation)

[Shri Borde]

In the past, there had been issues with UIAutomation as mentioned in http://blogs.msdn.com/shrib/archive/2008/03/24/ironpython-cannot-call-automationelement-fromhandle.aspx. This could be related. You could try it on Win7 to see if its fixed.

You can also try the techniques mentioned in http://blogs.msdn.com/shrib/archive/2008/03/24/what-if-a-c-snippet-does-not-work-when-transliterated-to-ironpython.aspx to narrow down the problem.

Subject: [IronPython] What's wrong with IronPython (UIAutomation)

Hi,

I'm using UIAutomation framework with IronPython to test our application.
For WPF dialogs it works perfectly. But I run into trouble when try to use it for some older dialogs.

The problem:  With IronPython I'm not able to get proper control type. Any controls appears as ControlType.Pane

Simple example: (with windows calculator)
--------------------------------------- IP Code ------------------------------------------------------
import clr

clr.AddReference('UIAutomationClient')
clr.AddReference('UIAutomationTypes')

from System.Windows.Automation import *

_rootElement = AutomationElement.RootElement

if __name__ == '__main__':

nameCondition = PropertyCondition(AutomationElement.NameProperty, "Calculator")
typeCondition = PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Window)
calcCondition = AndCondition(nameCondition, typeCondition)
appCalc = _rootElement.FindFirst(TreeScope.Children, calcCondition)

if appCalc is not None:

isFocusable = appCalc.GetCurrentPropertyValue(AutomationElement.IsKeyboardFocusableProperty, True)

if isFocusable:
#appCalc.SetFocus()   #calling this raise: System.InvalidOperationException
pass

contList = appCalc.FindAll(TreeScope.Subtree, Condition.TrueCondition)

for elm in contList:
progName = elm.Current.ControlType.ProgrammaticName
print progName
-----------------------------------------------------------------------------------------------------------
above code produce following output:

ControlType.Window
ControlType.Pane
ControlType.Pane
ControlType.Pane
ControlType.Pane
ControlType.Pane
.
.
.


similar C# code works as expected
------------------------------------------ C# Code ---------------------------------------------------
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Automation;
using Automation = System.Windows.Automation;

namespace UIAutTest
{
class Program
{
static void Main(string[] args)
{
AutomationElement rootElement = AutomationElement.RootElement;

Automation.Condition nameCondition = new PropertyCondition(AutomationElement.NameProperty, "Calculator");
Automation.Condition controlCondition = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Window);
Automation.Condition calcCondition = new AndCondition(nameCondition, controlCondition);
AutomationElement appCalc = rootElement.FindFirst(TreeScope.Children, calcCondition);


if (appCalc != null)
{
appCalc.SetFocus();

AutomationElementCollection allCont = appCalc.FindAll(TreeScope.Subtree, Condition.TrueCondition);
foreach (AutomationElement elm in allCont)
{
string contProgNam = elm.Current.ControlType.ProgrammaticName;
Console.WriteLine(contProgNam);
}
}

}
}
}
---------------------------------------------------------------------------------------------
C# code produce this output:

ControlType.Window
ControlType.Edit
ControlType.CheckBox
ControlType.CheckBox
ControlType.Group
ControlType.Button
ControlType.RadioButton
ControlType.RadioButton
ControlType.RadioButton
ControlType.RadioButton
ControlType.Group
ControlType.Group
ControlType.RadioButton
ControlType.RadioButton
ControlType.RadioButton
ControlType.Button
.
.


Does anybody know why ControlType property retrieved by IP code is different then ControlType retrieved by C# ?
Others element properties retrieved by IP code seems to by OK.

Info:
Windows Vista Business, SP2
IronPython 2.6 (2.6.10920.0) on .NET 2.0.50727.4200

Thanks,
Jozef
