How to get the class name inside a child window using pywinauto?

I am trying to automate an app using pywinauto. Here is a problem when I need to locate a specific window.

For example, I want to get the window 'AfxWnd4214', but I can only access to window "AfxWnd42".

   | AfxWnd42 - ''    (L1044, T410, R1060, B426)
   | ['AfxWnd4214', 'V11.82AfxWnd4212']
   | child_window(class_name="AfxWnd42")

   | AfxWnd42 - ''    (L1044, T410, R1060, B426)
   | ['AfxWnd4212', 'V11.82AfxWnd4212']
   | child_window(class_name="AfxWnd42")

I access it by this code. But it is not specific enough. The sequence of this window may change in the tree.

pywinauto.app.window(class_name = "AfxWnd42", found_index = 0)

When I try this code:

pywinauto.app.window(class_name = "AfxWnd4214", found_index = 0)

It says

pywinauto.findwindows.ElementNotFoundError: {'class_name': 'AfxWnd4214', 'found_index': 0, 'backend': 'win32', 'process': 15404}

Is there any better method to access this window?

Thank you.

Solution

There are various search criteria see below; Try using combination of these. Once I used auto_id and it worked for me.

''' Find elements based on criteria passed in

Possible values are:

* **class_name**     Elements with this window class
