get LegacyAccessibleName from item in TreeView. UIAutomation

FordsFinest · February 18, 2019

First time posting here, so i'm sure I am going to violate some sort of rule...But I am totally new to UIAutomation and am having a heck of time completing a simple task.

I need to verify the name of an item in a SysTreeView32 is a certain string. I've spent days trying every GUI_CtrlTreeView command out there with no success. I downloaded this Inspect.exe tool that was helpful in showing me there was no text for the item. The string i'm looking for WAS located under Name and Legacy Accessible Name however, but I am not sure how to check that property for a selected item.

Any help would be much appreciated!!

Here is a snapshot of the Window Info and the tree I am trying to access.

lastly, here is the Inspect Info.

FordsFinest, I can help you. And I don't think you've violated any rules.

You'll need to download UIASpy, run the script, place the mouse cursor over the Plant item (I assume that's the item in question), press F1, right-click in the listview in UIASpy, and copy all rows.

Then add a new post and paste the rows into the post. Use the <>-button at the top as you can see when creating a new post. Then you can paste the rows as text.

Then I'll see what I can do.

Lars.

That's too cool. Thanks a lot for the help. I actually need to click "LAP_VOW" and eventually an item located within that as well. I created an array of all the handles under "Plant" and click everything just fine, but I'm trying to add some robustness to it by checking the name of the item as well. This way if the list is ever changed i'm not just referencing array[16].

EndFunc

The code first creates the $oUIAutomation object and finds the Desktop item.

Then the top window is identified by the name and $oWindow1 is created.

The Treeview control is identified through class name and $oTree1 is created.

LAP_VOW treview item is identified and created using the name.

Finally, the name of the treview item is printed via $UIA_NamePropertyId.

Note that it's not necessary to use $UIA_LegacyIAccessibleNamePropertyId. You can use $UIA_NamePropertyId.

The Plant item must be expanded as shown in the picture. If it's collapsed, it can be expanded with the Expand() method of the ExpandCollapse Pattern object, which is available.

It's also possible to read the names of all treeview items under Plant if you need it.

Add a new post if the code doesn't work or if you have any questions.

Nice! I've ran into a couple problems though. The Reporting Client Window name will often have a different ending (e.g. Reporting Client - Perceptron - Navigation - [Navigation], etc.) The first four words stay the same, but will sometimes have something else added. I've typically used a wildcard to get around this but it didn't like it here...

But, for now, I updated the name and ran it again but haven't been able to get it past the first "Find treeview" section.

$oUIAutomation OK
$oDesktop OK
--- Find "Reporting Client - Perceptron - Navigation" window ---
$pCondition0 OK
$oWindow1 OK
--- Find treeview ---
$pCondition1 OK
$oTree1 ERR

I used your UIASpy tool to recreate the sample code for the tree and everything seemed to match, so I'm not sure why it's not finding the tree.

If you'll show information for the application window, we can surely find the window using the class name without using the window title.

Parent to child index

Ah. Found a work around for the title issue since class name kept changing too. I used WinGetTitle("[ACTIVE]").

Now that just leaves me with the tree issue. I've tried activating the window prior to looking for the tree, as well as looking for the parents of the tree first but no success...

$oUIAutomation OK
$oDesktop OK
--- Find "Reporting Client - Perceptron - Navigation" window ---
$pCondition0 OK
$oWindow1 OK
--- Find treeview ---
$pCondition1 OK
$oTree1 ERR

LarsJ · February 19, 2019

Have you clicked a treeview item as you did in the picture in first post?

FordsFinest · February 19, 2019

Ahah! I changed it from using $UIA_NamePropertyId to $UIA_ClassNamePropertyId when finding the "Reporting Client" Window and it worked!

Thanks again for the help and a good into to UIA.

FordsFinest · February 19, 2019

Hey @LarsJ, let me know if I should create a new thread, but this still kind of falls under this post...

Is it possible to read all the names of the children under Plant into an array? Then do the same thing with LAP_VOW.. I've had more success using standard action buttons. The software hasn't been consistent when using UIA. Since UIA is still the only way I know to read the names of the items in the tree view, I was hoping to make an array of them and then use a For loop to look through the array and click an item with standard action buttons.

LarsJ · February 20, 2019

I think it's fine to continue this thread.

I'm not quite sure if you can blame the UIA-code for the inconsistency, though it may be convenient.

You can load all Plant childs into an array ($aChilds) this way:

#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7

;#AutoIt3Wrapper_UseX64=n ; If target application is running as 32 bit code
;#AutoIt3Wrapper_UseX64=y ; If target application is running as 64 bit code

I made a mistake in the previous code:

ConsoleWrite( "--- Find treeview item ---" & @CRLF )

Local $pCondition2, $pCondition3, $pAndCondition3
$oUIAutomation.CreatePropertyCondition( $UIA_ControlTypePropertyId, $UIA_TreeItemControlTypeId, $pCondition2 )

$oUIAutomation.CreateAndCondition( $pCondition2, $pCondition3, $pAndCondition3 )
If Not $pAndCondition3 Then Return ConsoleWrite( "$pAndCondition3 ERR" & @CRLF )
ConsoleWrite( "$pAndCondition3 OK" & @CRLF )

Local $pTreeItem1, $oTreeItem1
$oWindow1.FindFirst( $TreeScope_Descendants, $pAndCondition3, $pTreeItem1 )
$oTreeItem1 = ObjCreateInterface( $pTreeItem1, $sIID_IUIAutomationElement, $dtagIUIAutomationElement )
If Not IsObj( $oTreeItem1 ) Then Return ConsoleWrite( "$oTreeItem1 ERR" & @CRLF )
ConsoleWrite( "$oTreeItem1 OK" & @CRLF )

Replace $oWindow1 with $oTree1.

I don't think the error has had any consequences. You got the right result anyway.

Man...I can't express my gratitude enough. It worked great! I used StringInStr to check the items in the array and then _GUICtrlTreeView_ClickItem... I'm not sure why I was having the previous trouble. I used UIA to select an item, but once I invoked a button to "Set Sample Size", it brought up a menu for the wrong tree item. Everything in the UIASpy said it the correct tree item was selected, focused, etc, matching exactly as if I had clicked the tree item with my own mouse. But still the issue was occurring.

But this works great and i'll be using it for many other things now too!

LarsJ · February 20, 2019

You're welcome. There will be a major update of UIASpy in the weekend. The new version is much better than the old one. Don't miss it.

get LegacyAccessibleName from item in TreeView. UIAutomation
