Using UI Automation Code in AutoIt

[seadoggie01]

I couldn't identify the dropdown separately from the rest of the MenuItem and UIA Spy didn't seem to see it either. I tried navigating with the function keys, but even then it didn't see it. I'm not sure where to go from here... should I just click it?

Edit: So there's a setting I can change to turn the menu item into a button... but then I need to right click it to expand the menu, is that possible instead?

Edit2: Found it, UIA_MouseClick

Uiaclick determines the rectangle and mousemove puts pointer in center before sending mouseclick. This way you prevent frezing your script.

[seadoggie01]

Thanks junkew! UIA_MouseClick does the same thing (and it hides the mouse while clicking, which I never thought of before)

UIA updates
The examples here show how Sample code (created through the Detail info listview page and the Sample code menu in UIASpy) looks when the code is generated under different Windows modes (Options | Windows | Mode menu in UIASpy). Note the version differences in CLSID_CUIAutomation as well as the main $oUIAutomation and $oUIElement objects.

When you select Windows mode through the Options | Windows | Mode menu, UIASpy will generate correct Sample code for this Windows version and use the correct CLSID_CUIAutomation version and the correct versions of the main $oUIAutomation and $oUIElement objects.

Code is stored in Examples\7) UIA updates\Notepad\ folder. The examples show code generated under Windows 7, Windows 8, Windows 8.1, Windows 10 First (1507) and Windows 10 Last (1809) modes. The code boxes below show code for Windows 7 and Windows 10 Last modes.

Patterns (actions), 16 - 17
Control patterns are objects that can be used to perform actions on an UI element (window/control). The actual actions are performed by executing the methods of the pattern objects.

Control types that are supported by specific control patterns are listed in Control Types and Their Supported Control Patterns.

How to create pattern objects and execute pattern methods through UIASpy is described in How to topics 12 and 14.

The examples shows how to use control patterns. The examples are tested on Windows 10 and Windows 7.

In many examples you need to update eg. control names to your own names. There may also be other values to be updated. Lines to be updated are marked with

; <<<<<<<<<<<<<<<<<<<<

Use UIASpy to check and copy the values.

All code is stored in Examples\4) Patterns (actions)\<Pattern>\ folders.
 

Patterns (actions):

• Section 1 - 12: Examples based on File Explorer
• Section 13 - 15: Virtual listview item patterns
• Section 16 - 17: Other control pattern objects
   

1. File Explorer picture
   
   Window patterns
2. Window Control Pattern
3. Transform Control Pattern
   
   Treeview patterns
4. ExpandCollapse Control Pattern
5. ScrollItem Control Pattern
6. Scroll Control Pattern
   Does not work on Windows 7 ($oScrollPattern1 ERR)
   
   Listview patterns
7. Grid Control Pattern
8. Table Control Pattern
9. Invoke Control Pattern
10. MultipleView Control Pattern
11. SelectionItem Control Pattern
12. Selection Control Pattern
    
    Virtual listview item patterns
13. File Explorer picture
14. ItemContainer Control Pattern
15. VirtualizedItem Control Pattern
    
    Other control pattern objects
16. Value Control Pattern
17. RangeValue Control Pattern  (SetValue())

 

16. Value Control Pattern
From Microsoft documentation:
The Value control pattern is used to support controls that have an intrinsic value not spanning a range and that can be represented as a string.

An Edit control is an obvious example.

Preparation
Open an empty WordPad window. Open UIASpy, place the mouse over the Edit control, press F1.

Code
The code in Value.au3 shows how to set a text value in the Edit control (Value-a.au3 contains code directly from UIASpy):

Remarks
Note that there are several changes to the new code compared to the old code in the previous examples from March 2019.
 

17. RangeValue Control Pattern
From Microsoft documentation:
The RangeValue control pattern is used to support controls that can be set to a value within a range.

Eg. a Slider control.

Preparation
Open an empty WordPad window. Enter a short text in the Edit control. The Slider control in the lower right corner should display the value 100%. Open UIASpy, place the mouse over the Slider control, press F2.

Code
RangeValue.au3 shows how to set the Slider value to zoom in to 300% (RangeValue-a.au3 contains code directly from UIASpy):

UIA events
The "FocusChangedEventHandler example" section of the first post in the "UI Automation Events" thread also contains brief descriptions of examples demonstrating the use of AutomationEventHandler, PropertyChangedEventHandler, and StructureChangedEventHandler. These four event handlers are available in all Windows versions from Windows XP to Windows 10.

A later post describes an example demonstrating the use of the NotificationEventHandler added in Windows 10 1709.

I am getting familiar with AutoiT and am using the UIASpy automation tool in my current automation effort that deals with Rocket Shuttle.

I am trying to get the child Window / Control from the desktop object using the processid.

However, I am running into this error.

$oUIAutomation.CreatePropertyCondition($UIA_ProcessIdPropertyId, $Pid, $pCondition0) gives back a HRESULT of -2147024809 which is invalid args.

The $Pid is the result of the RUN command. I understand that the 2nd argument to the function is a Variant. I am at loss to see how I can convert the $pid to a VT_I4 variant.

The code works fine if I pass a hardcoded process id integer value.

 

Thanks.

[LarsJ]

The problem is that Run() returns the PID as a variant of type double (VT_R8). You can find out with the VarGetType() function. All AutoIt variables are variants. But you can easily convert this double to an integer with the Int() function.

[tsrkumar]

Thanks Larsj!  that did the trick!

Appreciate the insight into AutoIt variables and the way to obtain their type.

Larsj

Is there any way to look up what each type of variant each propertyidentifier expects? For example, if I want to use the $UIA_NativeWindowHandlePropertyId and pass the windows handle so that I can convert the window handle variable to the appropriate type as i did with the above example per your solution.

 

Edit : My bad. should have read the microsoft documentation in detail before posting this. I was able to reference the different property identifiers and the expected variant type values for each. Sorry about that.

The most detail you can find in the windows sdk headerfiles.

[frank10]

First, thanks for UIASpy and the explanations!

Using it to create sample code, often it uses this var: $dtag_IUIAutomationElement

like this for taskbar:

Local $pCondition0
    $oUIAutomation.CreatePropertyCondition( $UIA_ClassNamePropertyId, "Shell_TrayWnd", $pCondition0 )
    If Not $pCondition0 Then Return ConsoleWrite( "$pCondition0 ERR" & @CRLF )
    ConsoleWrite( "$pCondition0 OK" & @CRLF )
    
    Local $pPane1, $oPane1
    $oDesktop.FindFirst( $TreeScope_Children, $pCondition0, $pPane1 )
    $oPane1 = ObjCreateInterface( $pPane1, $sIID_IUIAutomationElement, $dtag_IUIAutomationElement )
    If Not IsObj( $oPane1 ) Then Return ConsoleWrite( "$oPane1 ERR" & @CRLF )
    ConsoleWrite( "$oPane1 OK" & @CRLF )

But then, with

#include "Includes\CUIAutomation2.au3"

it gives

error: $dtag_IUIAutomationElement: undeclared global variable.

if I put

#include "Includes\UIA_Constants.au3"

it gives other errors on a lot of other vars.
        
So, I ended up using

#include "Includes\CUIAutomation2.au3"

and modifying the var to

$dtagIUIAutomationElement

and all works fine.

Is it a bug of UIASpy sample code generation?

Or which includes are to be used?

I want to click on a program in the TrayNotify, but inspecting it it has no NameProperty nor Classname!

 

 

So, how  can I directly select it?

I tried this way, of course with no luck, (it goes on the start of the trayNotify on the first Button):

Local $pCondition4
    $oUIAutomation.CreatePropertyCondition( $UIA_ControlTypePropertyId, $UIA_ButtonControlTypeId, $pCondition4 )
    If Not $pCondition4 Then Return ConsoleWrite( "$pCondition4 ERR" & @CRLF )
    ConsoleWrite( "$pCondition4 OK" & @CRLF )
    Local $pButton1, $oButton1
    $oPane3.FindFirst( $TreeScope_Descendants, $pCondition4, $pButton1 )
    $oButton1 = ObjCreateInterface( $pButton1, $sIID_IUIAutomationElement, $dtagIUIAutomationElement )
    If Not IsObj( $oButton1 ) Then Return ConsoleWrite( "$oButton1 ERR" & @CRLF )
    ConsoleWrite( "$oButton1 OK" & @CRLF )
    
    Local $asBoundingRectangle1
    $oButton1.GetCurrentPropertyValue( $UIA_BoundingRectanglePropertyId, $asBoundingRectangle1 )
    MouseMove($asBoundingRectangle1[0], $asBoundingRectangle1[1])

$oPane3 was the ToolbarWindow32, correctly selected.

 EDIT

I found a way with FindAll and checking for

UIA_NamePropertyId

when it is ""

But this is not so precise... what if one finds 2 buttons without a Name? How could I discriminate them?

Ideally it should be checked against the process Name ID on Task Manager. How?

Many thanks to LarsJ and junkew for their work on UI Automation in AutoIt! This is very, very helpful, many thanks!

Alas, I need to automate a poorly accessible application non-unique names, up to 18 sublevels of children etc. To put a long story short: I would like to use the "ElementFromPoint" method the get quickly an element from its screen coordinates.

Does anyone have a working example for the ElementFromPoint method as listed in UIA_Constants.au3?

Here is some example code for Notepad, but it is not working.

$oUIAutomation OK
$oDesktop OK
"\\Client\D$\Sonstiges\AutoIt\sys\_UIAutomation\test_AppNotepad.au3" (34) : ==> The requested action with this object has failed.:
$oDesktop.ElementFromPoint($tStructPoint, $pElement)
$oDesktop^ ERROR

Can anyone give me a hint why the error occurs and how to do it right?

Thank you so much, InnI! This indeed does the trick! 😊

Here is a performance tip on finding the top level window from the usual Desktop object. The gain will vary depending on how much stuff is open in your tree (UISpy's left pane).

My assumption on how the tree walker works could be wrong, but this is my observation. The difference is letting the FindAll method drill down through every...single...subelement, or tell it to just go one level down. I wrapped a timer around the two approaches to show the speed gain. Sure, it's milliseconds, but it accumulates the more your script runs through objects.

Low number of windows open:

• Timer $TreeScope_Descendants: 124.508
• Timer $TreeScope_Children: 9.635

15 extra File Explorer windows open:

• Timer $TreeScope_Descendants: 155.358
• Timer $TreeScope_Children: 10.055

So again, you have to know for certain that the element that you are looking for is only one level down from the parent, or your element will not be found.

When you're working against a client application, not OS objects directly like the System Tray or etc., you can skip the step of getting the Desktop object then using its FindAll method, and go straight to your client application by hWnd which can be retrieved by the good old Windows Management functions like WinGetHandle().

This example comments out the lines that connect to the Desktop object, then use that to connect to the Chrome window. It also shows that you don't need to make Chrome the active window and it will still work fine. We're familiar with that concept from our days of working with Window Management and Controls. By the way, this is also faster than the the other way.

Doing my part to update us on how the changes in Chrome have caused us to have to change the example script "Chrome - Clicking an extension" which was actually how to open a new tab in Chrome. That answer uses MouseClick because the Invoke method didn't work at that time. I'm going to guess that was a Chrome issue for that older version because it works now. Being able to use the UIA Invoke means that Chrome windows does not have to be the active window, but it will become the active window to the New Tab. This example also uses the approach of setting the client application's UIA object by its hWnd rather than a FindAll from the Desktop object.

The WinGetHandle() code is about 30 milliseconds faster on average.
There may be many good reasons to use the WinGetHandle() function, but I don't think performance considerations are crucial.
