Использование АХК PostMessage/SendMessage или DllCall («SendMessage», чтобы получить содержимое элемент списка

Question

Я пытаюсь получить содержимое элемент списка в другом приложении с использованием AHK. Я попытался с помощью

ControlGet, List, List,, ListViewWndClass1, WindowTitle 

в AutoHotKey, но это не сработало, есть ли способ, чтобы получить содержимое ListView управления с использованием AHK PostMessage/SendMessage или DllCall ("SendMessage"

Попробуйте это:.?

Должно работать примерно так:

WinGet, hWnd, ID, My WinTitle 
GetListViewItemText(1, 1, "ListViewWndClass1", hWnd)
