I am not able to read text from textbox in windows calculator

With windows 10 calculator you have to read to history listview.

With forexample following pascal code (sorry this is Finnish but you get the point)

  showmessage( Sys.Process('Microsoft.WindowsCalculator').UIAObject('Laskin').UIAObject('DockPivot').UIAObject('Historia').UIAObject('HistoryListView').UIAObject('ListViewItem').UIAObject('resultTextBlock').text);
