UI Automation Events

LarsJ · December 8, 2019

UI Automation Events
In standard Windows GUI code, you can respond to Windows messages by registering and implementing a message handler function. A WM_NOTIFY message handler is registered and implemented in this way:

; Registration
GUIRegisterMsg( $WM_NOTIFY, "WM_NOTIFY" )

; Implementation
Func WM_NOTIFY( $hWnd, $iMsg, $wParam, $lParam )
  ; Code
EndFunc

The WM_NOTIFY function is a callback function.

In UI Automation code, you can respond to UI Automation events by registering and implementing an event handler object. A FocusChangedEventHandler object is registered and implemented in this way:

; Registration
UIAEH_FocusChangedEventHandlerCreate()
$oUIAutomation.AddFocusChangedEventHandler( 0, $oUIAEH_FocusChangedEventHandler )

; Implementation
; This is the function that receives events
Func UIAEH_FocusChangedEventHandler_HandleFocusChangedEvent( $pSelf, $pSender )
  ; Code
EndFunc

$oUIAEH_FocusChangedEventHandler is the event handler object. It's a callback object.

This thread is about how to respond to UI Automation events by registering, implementing and using event handler objects.

User Defined Functions
Registering and implementing the event handler object in the code above is very simple. To make it that simple, it's necessary to include a few functions in a UDF. The zip-file at bottom of post contains a UIAEH_FocusChangedEventHandler.au3 UDF that allows the registration and implementation of the event handler object as simple as shown above.

UIAEH_FocusChangedEventHandlerCreate() is a function in this UDF. The function creates the $oUIAEH_FocusChangedEventHandler object. Because this is a callback object it must be implemented through ObjectFromTag() (coded in ObjectFromTag.au3 in zip-file) function by trancexx and not through the usual ObjCreateInterface() which is used to create other UI Automation objects. (The warning at top of the help text is much more an error in the help text than an error in the function. Thousands of examples show that ObjCreateInterface() works flawlessly.)

You don't need to use ObjectFromTag() in your own code. This function is completely handled in the UDFs.

UIAEH_FocusChangedEventHandler_HandleFocusChangedEvent() is the function that receives events. This function is coded but commented out in UIAEH_FocusChangedEventHandler.au3. Copy this function to your own code. See FocusChangedEventHandler example below.

UIA Event Handlers
The first version of Microsoft's UI Automation code (the Windows 7 version that works on Windows XP, Windows Vista, Windows 7 and all later versions) implements four different event handler objects. In addition to the FocusChangedEventHandler object, it's the AutomationEventHandler, PropertyChangedEventHandler and StructureChangedEventHandler objects. The zip-file at the bottom contains the corresponding three event handler UDFs.

By the way, these four event handlers are implemented in AutoIt several years ago in this and the following posts.

FocusChangedEventHandler exposes a method to handle events that are raised when the keyboard focus moves to another UI Automation element.

AutomationEventHandler exposes a method to handle Microsoft UI Automation events. These events include MenuOpened ($UIA_MenuOpenedEventId) and Window_WindowOpened ($UIA_Window_WindowOpenedEventId) events. See module UIA_EventIds in UIA_Constants.au3 for a complete list. Note that EventIds that belong to Windows 8 or later cannot be used in this version of the event handler. But they can be used after code updates over the coming weeks.

2019-12-15 If you select Desktop, AutomationEvent and all Events (Event Ids) in UI Automation Event Monitor below and click Start, you'll see the following output in SciTE console:

$oUIAEH_AutomationEventHandler OK
Desktop: AddAutomationEventHandler() = AsyncContentLoaded OK
Desktop: AddAutomationEventHandler() = AutomationFocusChanged ERR
Desktop: AddAutomationEventHandler() = AutomationPropertyChanged OK
Desktop: AddAutomationEventHandler() = InputDiscarded OK
Desktop: AddAutomationEventHandler() = InputReachedOtherElement OK
Desktop: AddAutomationEventHandler() = InputReachedTarget OK
Desktop: AddAutomationEventHandler() = Invoke_Invoked OK
Desktop: AddAutomationEventHandler() = LayoutInvalidated OK
Desktop: AddAutomationEventHandler() = MenuClosed OK
Desktop: AddAutomationEventHandler() = MenuModeEnd OK
Desktop: AddAutomationEventHandler() = MenuModeStart OK
Desktop: AddAutomationEventHandler() = MenuOpened OK
Desktop: AddAutomationEventHandler() = Selection_Invalidated OK
Desktop: AddAutomationEventHandler() = SelectionItem_ElementAddedToSelection OK
Desktop: AddAutomationEventHandler() = SelectionItem_ElementRemovedFromSelection OK
Desktop: AddAutomationEventHandler() = SelectionItem_ElementSelected OK
Desktop: AddAutomationEventHandler() = StructureChanged OK
Desktop: AddAutomationEventHandler() = Text_TextChanged OK
Desktop: AddAutomationEventHandler() = Text_TextSelectionChanged OK
Desktop: AddAutomationEventHandler() = ToolTipClosed OK
Desktop: AddAutomationEventHandler() = ToolTipOpened OK
Desktop: AddAutomationEventHandler() = Window_WindowClosed OK
Desktop: AddAutomationEventHandler() = Window_WindowOpened OK

Note the error for the AutomationFocusChanged event handler (at the top of the list). I've found that there is an error, but so far have no explanation for it.

PropertyChangedEventHandler exposes a method to handle Microsoft UI Automation events that occur when a property is changed. These events include Name ($UIA_NamePropertyId) and ValueValue ($UIA_ValueValuePropertyId) changes. See module UIA_PropertyIds in UIA_Constants.au3 for a complete list. Note that PropertyIds that belong to Windows 8 or later cannot be used in this version of the event handler. But they can be used after code updates over the coming weeks.

StructureChangedEventHandler exposes a method to handle events that occur when the Microsoft UI Automation tree structure is changed. This event handler seems to be more valuable in eg. screen readers than in usual UI Automation code.

NotificationEventHandler exposes a method to handle Microsoft UI Automation notification events. See this post.

FocusChangedEventHandler example
This is full code in Examples\FocusChangedEventHandlerEx.au3. Run the code in SciTE with F5.

Func UIAEH_GetCurrentPropertyValue( $oSender, $iPropertyId )
  Local $vPropertyValue
  $oSender.GetCurrentPropertyValue( $iPropertyId, $vPropertyValue )
  Return $vPropertyValue
EndFunc

Test the code by opening the Desktop context menu and move the mouse over the menu items. When the mouse hovers over a menu item it gets focus. Exit with Esc.

AutomationEventHandlerEx.au3 Test the example by opening some windows, menus and tooltips.

PropertyChangedEventHandlerEx.au3 Open Windows Task Manager (Ctrl+Shift+Esc) and you'll get a whole bunch of property changed events. Note that to access Windows Task Manager (and other programs) on Windows 10, use #RequireAdmin in the script and run SciTE as administrator.

StructureChangedEventHandlerEx.au3 Clicking on a folder in File/Windows Explorer treeview generates a lot of structure changed events.

New examples will be added over the coming weeks.

UI Automation Event Monitor
UI Automation Event Monitor is a tool to detect UI Automation events.

The first group of toolbar buttons is used to set up the UI Automation event handler. The images have a PropertyChangedEventHandler set up to monitor Name ($UIA_NamePropertyId) and ValueValue ($UIA_ValueValuePropertyId) property changes in Windows Task Manager. Note that to access Windows Task Manager (and other programs) on Windows 10, use #RequireAdmin in the script (UIAEHEvents.au3) and run SciTE as administrator.

These four toolbar buttons are hot-track enabled with the technique used in this example. The buttons open four listviews to set up the event handler. All listviews have multiple selections enabled. Select multiple items at once and check a single item in/out to check all selected items in/out. Use mouse or Space key to check an item in/out.

In the first image, the mouse hovers over the Top Windows button so that it's selected. In the second image, the Top Windows button is clicked so that the listview is opened. Moving the mouse over the next three buttons automatically opens the corresponding listviews due to hot-tracking. Click the toolbar button again to close the listview or move the mouse above the title bar. Windows Task Manager is checked in the Top Windows listview.

The Event Handlers listview is enabled when a Top Window is checked. The Event Ids listview is enabled when the AutomationEvent event handler is checked. The Property Ids listview is enabled when the PropertyChanged event handler is checked.

In Event Ids and Property Ids listview you can select an item by pressing the first letter on the keyboard.

The second group of toolbar buttons is used to Start/Stop the event handler (or multiple event handlers), Pause/Continue updating the Events listview, and Clear the listview. Note that the Pause button only stops updating the listview. Events are still detected and stored in $aEvents array. All new events are added at the bottom of the listview when you click Continue or Stop.

The Pause Main Loop button is used to stop the GUI main loop, which significantly increases the performance of the Events listview. When the GUI main loop is paused you can only click the Continue Main Loop button (same button as Pause Main Loop) and you can close the GUI.

Events listview
The Events listview is a virtual listview because of performance and to make it easy to constantly add new rows to the bottom of the listview. Nevertheless, there can still be performance issues when a lot of events are generated. To remedy these issues, it's possible to stop the GUI main loop with the Pause Main Loop button. This significantly increases the performance of the Events listview.

When there are a large number of events (when many new rows are added quickly at the bottom of the listview), this procedure must be followed to stop the event handler (or multiple event handlers): Make sure the GUI main loop isn't paused. Click the Pause button (second toolbar group) to pause Events listview updates. Click the Stop button to stop the event handler. When there are a small number of events you can immediately click the Stop button.

To test the UI Automation Event Monitor, try performing the four examples (in Examples\, briefly described above) through the monitor GUI.

There'll probably be some GUI updates in the coming weeks.

UIA Menu, Tooltip and Window Events Monitor is a simpler version of UI Automation Event Monitor that detects only MenuOpened, ToolTipOpened and Window_WindowOpened events (AutomationEvents).

UIA Menu, Tooltip and Window Events Monitor
UIA Menu, Tooltip and Window Events Monitor is a simpler version of UI Automation Event Monitor (first post) that detects only MenuOpened, ToolTipOpened and Window_WindowOpened events (AutomationEvents):

Click Start to begin event detection.

A single CheckboxCombo control is used to choose between Menu, Tooltip and Window Opened events.

The buttons work the same way as described for the GUI in first post.

The listview shows the events generated when Google Chrome is opened, when the mouse hovers over the Customize button (the three vertical dots in upper right corner) so that a Tooltip is displayed, and when the Customize button is clicked so that the Customize menu pops up.

For Tooltips and Windows, the first level child controls are also displayed in the listview. For Menus, all child controls are displayed.

A right-click context menu is added to the listview. It's only applicable if the listview update is Paused or Stopped. The context menu provides access to copy selected or all items to clipboard. (The context menu will be added to the listview in first post in a later update.) The clipboard gets this content when all items in the listview above are copied:

1    Window_WindowOpened    Pane: about:blank - Google Chrome, 0x0001034E
                                Document: Chrome_RenderWidgetHostHWND, 0x00010352
                                TitleBar
                                Pane: Google Chrome
2    ToolTipOpened          ToolTip: Customize and control Google Chrome, 0x00040242
3    MenuOpened             Pane: Chrome_WidgetWin_2, 0x00010360
                                MenuBar
                                    Pane
                                        Menu
                                            MenuItem: New tab Ctrl+T
                                            MenuItem: New window Ctrl+N
                                            MenuItem: New incognito window Ctrl+Shift+N
                                            Pane
                                            MenuItem: History
                                            MenuItem: Downloads Ctrl+J
                                            MenuItem: Bookmarks
                                            Pane
                                            MenuItem: Zoom
                                                Menu
                                                    MenuItem: Make Text Smaller
                                                    Custom: 100%
                                                    MenuItem: Make Text Larger
                                                    MenuItem: Full screen F11
                                            Pane
                                            MenuItem: Print… Ctrl+P
                                            MenuItem: Cast…
                                            MenuItem: Find… Ctrl+F
                                            MenuItem: More tools
                                            Pane
                                            MenuItem: Edit
                                                Menu
                                                    MenuItem: Cut Ctrl+X
                                                    MenuItem: Copy Ctrl+C
                                                    MenuItem: Paste Ctrl+V
                                            Pane
                                            MenuItem: Settings
                                            MenuItem: Help
                                            Pane
                                            MenuItem: Exit

The reason I've made a separate GUI for these three events is that they are very useful events, but especially because I plan to add detection of these events in UIASpy. In UIASpy, it can be difficult to get information about menus, tooltips and popup and flyout windows (Windows 10 uses a whole lot of these windows) with the mouse and the F1 - F4 keys. But before I add the functionality to UIASpy, I want to make sure it works. Therefore, this GUI.

You need AutoIt 3.3.12 or later. Tested on Windows 7 and Windows 10. The code should run on all Windows versions.

Comments are welcome. Let me know if there are any issues.

Notepad context menu
Automating a context menu consists of opening the menu, detecting the open menu and clicking a menu item. Here, the technique is demonstrated with Notepad as an example and the "Right to left Reading order" menu item in the context menu of the Edit control. The inspiration for the example is found in this thread.

Opening the menu
A small two-button GUI is used to open the context menu by generating a secondary mouse click:

; Create AutoIt GUI
Local $hGui = GUICreate( "Automate Notepad Context Menu", 330, 40, 100, 100 )
Local $idRight = GUICtrlCreateButton( "Right to left Reading order",  10, 10, 150, 20 )
Local $idLeft  = GUICtrlCreateButton( "Left to right Reading order", 170, 10, 150, 20 )
GUICtrlSetState( $idLeft, $GUI_DISABLE )

; Show GUI
GUISetState( @SW_SHOW )

; Main loop
Local $iMsg
While 1
  $iMsg = GUIGetMsg()
  Switch $iMsg
    Case $idRight, $idLeft
      ; Secondary mouse click
      UIA_WinActivate( $oNotepad )
      UIA_WinWaitActive( $oNotepad )
      UIA_MouseClick( $oEdit1, True )
      GUICtrlSetState( $iMsg = $idRight ? $idRight : $idLeft, $GUI_DISABLE )
      GUICtrlSetState( $iMsg = $idRight ? $idLeft : $idRight, $GUI_ENABLE )
      ConsoleWrite( @CRLF & "Secondary mouse click" & @CRLF )

Detecting the open menu
The event handler to detect menu open events is created this way:

; Create UI Automation event handler
UIAEH_AutomationEventHandlerCreate()
If Not IsObj( $oUIAEH_AutomationEventHandler ) Then Return ConsoleWrite( "$oUIAEH_AutomationEventHandler ERR" & @CRLF )
ConsoleWrite( "$oUIAEH_AutomationEventHandler OK" & @CRLF )

; Detect menu open events
Local $iError = $oUIAutomation.AddAutomationEventHandler( $UIA_MenuOpenedEventId, $pDesktop, $TreeScope_Subtree, 0, $oUIAEH_AutomationEventHandler )
If $iError Then Return ConsoleWrite( "AddAutomationEventHandler() ERR" & @CRLF )
ConsoleWrite( "AddAutomationEventHandler() OK" & @CRLF )

This is the function that receives events. The event is sent to the AutoIt main loop using a dummy control, $idContextMenu:

; This is the function that receives events
Func UIAEH_AutomationEventHandler_HandleAutomationEvent( $pSelf, $pSender, $iEventId ) ; Ret: long  Par: ptr;int
  ConsoleWrite( "UIAEH_AutomationEventHandler_HandleAutomationEvent: $iEventId = " & $iEventId & @CRLF )
  $oContextMenu = ObjCreateInterface( $pSender, $sIID_IUIAutomationElement, $dtag_IUIAutomationElement )
  $oContextMenu.AddRef()
  If Not IsObj( $oContextMenu ) Then Return ConsoleWrite( "$oContextMenu ERR" & @CRLF )
  ConsoleWrite( "$oContextMenu OK" & @CRLF )
  GUICtrlSendToDummy( $idContextMenu )
  Return 0x00000000 ; $S_OK
  #forceref $pSelf
EndFunc

Clicking a menu item
And this is code that clicks the "Right to left Reading order" menu item:

Case $idContextMenu
  ; Context menu item
  Local $pAndCondition1
  $oUIAutomation.CreatePropertyCondition( $UIA_ControlTypePropertyId, $UIA_MenuItemControlTypeId, $pCondition0 )
  $oUIAutomation.CreatePropertyCondition( $UIA_NamePropertyId, "Right to left Reading order", $pCondition1 )
  $oUIAutomation.CreateAndCondition( $pCondition0, $pCondition1, $pAndCondition1 )
  If Not $pAndCondition1 Then Return ConsoleWrite( "$pAndCondition1 ERR" & @CRLF )
  ConsoleWrite( "$pAndCondition1 OK" & @CRLF )

  ; Find Context menu item
  Local $pMenuItem1, $oMenuItem1
  $oContextMenu.FindFirst( $TreeScope_Descendants, $pAndCondition1, $pMenuItem1 )
  $oMenuItem1 = ObjCreateInterface( $pMenuItem1, $sIID_IUIAutomationElement, $dtag_IUIAutomationElement )
  If Not IsObj( $oMenuItem1 ) Then Return ConsoleWrite( "$oMenuItem1 ERR" & @CRLF )
  ConsoleWrite( "$oMenuItem1 OK" & @CRLF )

  ; Click Context menu item
  Local $pInvokePattern1, $oInvokePattern1
  $oMenuItem1.GetCurrentPattern( $UIA_InvokePatternId, $pInvokePattern1 )
  $oInvokePattern1 = ObjCreateInterface( $pInvokePattern1, $sIID_IUIAutomationInvokePattern, $dtag_IUIAutomationInvokePattern )
  If Not IsObj( $oInvokePattern1 ) Then Return ConsoleWrite( "$oInvokePattern1 ERR" & @CRLF )
  ConsoleWrite( "$oInvokePattern1 OK" & @CRLF )
  $oInvokePattern1.Invoke()
  ConsoleWrite( "$oInvokePattern1.Invoke()" & @CRLF )

Full code in Examples\Notepad context menu\ContextMenu.au3. Note that because of the UIAEH_AutomationEventHandler.au3 UDF, the code in the example here is much simpler than the code in the link above.

To run the example open Notepad and enter or paste some text into the Edit control. Then run ContextMenu.au3 in SciTE with F5.

👍you covered the whole uia model with excellent examples in AutoIt coding. Not much left to give examples on.

Windows 8, Windows 8.1 and Windows 10 updates
In Windows 8 and later, new event handlers have been added and new events and property changes have been added to existing event handlers. This is an update to be able to take advantage of these new event handlers, events and property changes.

Four new event handlers have been added:

IUIAutomationTextEditTextChangedEventHandler       ; Windows 8.1
IUIAutomationChangesEventHandler                   ; Windows 10-1703
IUIAutomationNotificationEventHandler              ; Windows 10-1709
IUIAutomationActiveTextPositionChangedEventHandler ; Windows 10-1809

The corresponding four new EventIds that can be used in the existing AutomationEventHandler are:

Global Const $UIA_TextEdit_TextChangedEventId      = 20032 ; Windows 8.1
Global Const $UIA_ChangesEventId                   = 20034 ; Windows 10
Global Const $UIA_NotificationEventId              = 20035 ; Windows 10
Global Const $UIA_ActiveTextPositionChangedEventId = 20036 ; Windows 10

In addition to the listed EventIds, there are 10 more EventIds that can be used in the existing AutomationEventHandler. And there are more than 60 new PropertyIds that can be used in the existing PropertyChangedEventHandler.

By detecting events for the four new EventIds listed above in UI Automation Event Monitor (UIAEHEvents.au3, see description of updates below) I've tried to find applications that actually generates some of these new events. I've found that the Windows 10 Calculator and Microsoft Edge browser generates Notification events. With the new NotificationEventHandler it's possible to obtain further information about these events.

I've not found any applications that generates the other three events. And thus I've not found any applications where it's possible to test the new TextEditTextChangedEventHandler, ChangesEventHandler and ActiveTextPositionChangedEventHandler.

Therefore, the only new event handler implemented in this update is the NotificationEventHandler.

NotificationEventHandler
NotificationEventHandler exposes a method to handle Microsoft UI Automation notification events.

The UDF is implemented in Includes\UIAEH_NotificationEventHandler.au3:

#include-once
#include "UIA_Constants.au3"
#include "UIA_ConstNames.au3"
#include "UIA_Functions.au3"
#include "ObjectFromTag.au3"

NotificationKindSetNames()
NotificationProcessingSetNames()

Global $oUIAEH_NotificationEventHandler, $tUIAEH_NotificationEventHandler

Func UIAEH_NotificationEventHandlerCreate()
  $oUIAEH_NotificationEventHandler = ObjectFromTag( "UIAEH_NotificationEventHandler_", $dtag_IUIAutomationNotificationEventHandler, $tUIAEH_NotificationEventHandler, True )
EndFunc

Func UIAEH_NotificationEventHandlerDelete()
  $oUIAEH_NotificationEventHandler = 0
  DeleteObjectFromTag( $tUIAEH_NotificationEventHandler )
EndFunc

#cs
; Insert the two functions here in user code

; This is the function that receives events
Func UIAEH_NotificationEventHandler_HandleNotificationEvent( $pSelf, $pSender, $iKind, $iProcessing, $pDisplayStr, $pActivityId ) ; Ret: long  Par: ptr;long;long;ptr;ptr
  ConsoleWrite( @CRLF & "UIAEH_NotificationEventHandler_HandleNotificationEvent: $iKind = " & $aNotificationKindNames[$iKind] & @CRLF )
  ConsoleWrite( "UIAEH_NotificationEventHandler_HandleNotificationEvent: $iProcessing = " & $aNotificationProcessingNames[$iProcessing] & @CRLF )
  ConsoleWrite( "UIAEH_NotificationEventHandler_HandleNotificationEvent: $sDisplayStr = " & UIA_String( $pDisplayStr ) & @CRLF )
  ConsoleWrite( "UIAEH_NotificationEventHandler_HandleNotificationEvent: $sActivityId = " & UIA_String( $pActivityId ) & @CRLF )
  Local $oSender = ObjCreateInterface( $pSender, $sIID_IUIAutomationElement9, $dtag_IUIAutomationElement9 ) ; Windows 10 Last
  $oSender.AddRef()
  ConsoleWrite( "Title     = " & UIAEH_GetCurrentPropertyValue( $oSender, $UIA_NamePropertyId ) & @CRLF & _
                "Class     = " & UIAEH_GetCurrentPropertyValue( $oSender, $UIA_ClassNamePropertyId ) & @CRLF & _
                "Ctrl type = " & UIAEH_GetCurrentPropertyValue( $oSender, $UIA_ControlTypePropertyId ) & @CRLF & _
                "Ctrl name = " & UIAEH_GetCurrentPropertyValue( $oSender, $UIA_LocalizedControlTypePropertyId ) & @CRLF & _
                "Handle    = " & "0x" & Hex( UIAEH_GetCurrentPropertyValue( $oSender, $UIA_NativeWindowHandlePropertyId ) ) & @CRLF & _
                "Value     = " & UIAEH_GetCurrentPropertyValue( $oSender, $UIA_ValueValuePropertyId ) & @CRLF  )
  Return 0x00000000 ; $S_OK
  #forceref $pSelf
EndFunc

; Auxiliary function (for simple properties only)
; There must be only one instance of this function
Func UIAEH_GetCurrentPropertyValue( $oSender, $iPropertyId )
  Local $vPropertyValue
  $oSender.GetCurrentPropertyValue( $iPropertyId, $vPropertyValue )
  Return $vPropertyValue

AutomationEventHandler
For the existing AutomationEventHandler and for the other existing event handlers, comment lines have been added in both the UDF and the example about which version of the UIA objects to use. Comment lines are added like this:

Local $oUIAutomation = ObjCreateInterface( $sCLSID_CUIAutomation,  $sIID_IUIAutomation,  $dtag_IUIAutomation  ) ; Windows 7
;Local $oUIAutomation = ObjCreateInterface( $sCLSID_CUIAutomation8, $sIID_IUIAutomation2, $dtag_IUIAutomation2 ) ; Windows 8
;Local $oUIAutomation = ObjCreateInterface( $sCLSID_CUIAutomation8, $sIID_IUIAutomation3, $dtag_IUIAutomation3 ) ; Windows 8.1
;Local $oUIAutomation = ObjCreateInterface( $sCLSID_CUIAutomation8, $sIID_IUIAutomation3, $dtag_IUIAutomation3 ) ; Windows 10 First
;Local $oUIAutomation = ObjCreateInterface( $sCLSID_CUIAutomation8, $sIID_IUIAutomation6, $dtag_IUIAutomation6 ) ; Windows 10 Last

Local $oSender = ObjCreateInterface( $pSender, $sIID_IUIAutomationElement,  $dtag_IUIAutomationElement  ) ; Windows 7
;Local $oSender = ObjCreateInterface( $pSender, $sIID_IUIAutomationElement2, $dtag_IUIAutomationElement2 ) ; Windows 8
;Local $oSender = ObjCreateInterface( $pSender, $sIID_IUIAutomationElement3, $dtag_IUIAutomationElement3 ) ; Windows 8.1

;Local $oSender = ObjCreateInterface( $pSender, $sIID_IUIAutomationElement9, $dtag_IUIAutomationElement9 ) ; Windows 10 Last

UIAEHEvents.au3 updates
In order for UI Automation Event Monitor to be able to detect new events and property changes, the code has been updated to handle different Windows versions and thus different versions of the UIA objects. Handling multiple versions of Windows and multiple versions of the UIA objects is the same as in UIASpy. Through a new Options menu you can execute code that fits a particular Windows version.

Note that under Windows 7 and earlier versions, only the original four event handlers (AutomationEventHandler, FocusChangedEventHandler, PropertyChangedEventHandler, StructureChangedEventHandler) introduced in Windows 7 can be used.

In addition, some minor errors have been fixed and some of the code has been tightened up.

New zip-file at bottom of first post.

Wild guess but I think some of those events you did not find are related to xamarin forms. So if you make an c# with xamarin form and textboxes you will see them.

Why do event handlers call $oSender.AddRef() but do not call the matching $oSender.Release() once they are done with the object? Doesn't that lead to a memory leak?
