At least we have an element title: [Google Chrome] class: []

Having the following values for all properties: 
Title is: <Google Chrome>	Class   := <>	controltype:= <UIA_CustomControlTypeId>	,<50025>	, (0000C369)	2399;124;1354;820
*** Parent Information top down ***
0: Title is: <Outpatient Clinic Attendance>	Class   := <Chrome_WidgetWin_1>	controltype:= <UIA_WindowControlTypeId>	,<50032>	, (0000C370)	2394;124;1364;825
"Title:=Outpatient Clinic Attendance;controltype:=UIA_WindowControlTypeId;class:=Chrome_WidgetWin_1""	


;~ *** Standard code maintainable ***
#include "UIAWrappers.au3"
