Thanks Junkew
With this code i can read text, if i set coordinates. ( i moved the window to 0,0 )
fortunately coords are fixed in app
Local $tStruct = DllStructCreate($tagPOINT) ; Create a structure that defines the point to be checked.
Global $UIA_oUIAutomation ;The main library core CUI automation reference
Global $UIA_oUIElement, $UIA_pUIElement  ;Used frequently to get an element
DllStructSetData($tStruct, "x", 200)
DllStructSetData($tStruct, "y", 281)
$UIA_oUIAutomation.ElementFromPoint($tStruct,$UIA_pUIElement )
$oUIElement = objcreateinterface($UIA_pUIElement,$sIID_IUIAutomationElement, $dtagIUIAutomationElement)
If IsObj($oUIElement) Then
ConsoleWrite(_UIA_getPropertyValue($oUIElement, $UIA_NamePropertyId) & @CRLF)

example 11 should help you out (download examples of uiautomation thread)

But basically you first find your main window (to limit the number of elements to search)
Please check the examples.zip for latest syntax (example 4 and 11 should help you out)

$oNotepad=_UIA_getFirstObjectOfElement($UIA_oDesktop,"class:=Notepad", $treescope_children)

if isobj($oCalc) Then

get the element you want to do something with based on the properties

$sText="Bewerken"    ;Edit
    $oUIElement=_UIA_getFirstObjectOfElement($oCalc,"name:=" & $sText, $treescope_subtree)

get the property value you are interested in
