AutoIT Close Office Save / Don't Save Prompt

[Deb]

I want to close (click on save or don't save ) following Microsoft Office Save / Don't save prompt window using AutoIt(python version).

I tried based on the example given here : https://pypi.python.org/pypi/PyAutoIt/0.3

 

Here is my code:

import autoit
autoit.control_click("[Class:#NUIDialog]", "Button1")

Also tried

autoit.control_click("[CLASS:NetUIHWND; INSTANCE:1]", "Button1")

However, I'm getting fowling error :

Traceback (most recent call last):
  File "officetest.py", line 6, in <module>
    autoit.control_click("[CLASS:NetUIHWND; INSTANCE:1]", "Button1")
  File "c:\python27\lib\site-packages\pyautoit-0.3-py2.7.egg\autoit\autoit.py", line 80, in wrapper
    raise AutoItError(err_msg)
autoit.autoit.AutoItError: send click message failed

 

Can anyone please point out what am I doing wrong ?

Thanks in Advance.
