Cannot handle this class : XamlExplorerHostIslandWindow ! it is the Windows 11 Task view !

[Syla]

Hi, i'm trying to get the handle of this class but without success. All others WinGetHandle are working in my code, not this one. the WinWait before WinGetHandle launched when the window is activ does not see it and wait until i close it ! The Window info from Autoit is able to see and get every information, any idea would be really appreciate.

What happens if you use windows title? Show the code you are using. It might be easier someone to help you that way. If you copy handle from AutoIt info tool are you able to get any data for window?

[Syla]

if i use windows title it's the same problem ! i've tried to copy the handle given by the autoit app, but the handle number is changing at every new launch of it.

What @ahmet meant is : after you launch the application and you plug the handle into your code, do you have access to the window ?

Have you tried to use WinList instead ?  Maybe there is multiple windows with the same class ?

And please show your code when you ask for help.  Here how to post code.

Task View is launched by windows in full screen, i could get the handle but no way to use it without quit and relaunch again ( and then loose the handle ) !

WinList does not show it !!!

If "Always on top" don't do it, use Control Viewer.

Interesting but if Au3Inf is seeing it you should be able to handle it.
https://learn.microsoft.com/en-us/shows/visual-studio-toolbox/xaml-islands 

Try FAQ 31 with UIAutomation 

 

Whats the output of this

Example()

Func Example()
        ; Retrieve a list of window handles.
        Local $aList = WinList()

        ; Loop through the array displaying only visable windows with a title.
        For $i = 1 To $aList[0][0]
                If $aList[$i][0] <> "" And BitAND(WinGetState($aList[$i][1]), 2) Then
                        consolewrite("Title: " & $aList[$i][0] & @CRLF & "Handle: " & $aList[$i][1] & @CRLF)
                         ; Retrieve the classlist of the window using the handle returned .
                        Local $sClassList = WinGetClassList($aList[$i][1])
                        consolewrite(stringreplace($sClassList,@LF,@LF & " -")& @CRLF)
                EndIf
        Next
EndFunc   ;==>Example

console write is doing strange things actually in my side but if i print an array of classes + msgboxes of getting classes list of them, here is what i get: 2 msgbox were empty (no class list i guess)

i've tried to look at the handle i've got from The Window info from Autoit ( launched in the same time ), even in the all winlist results, ( not visible ). No way, i cannot find it.

Just to add a bit of context to this -  XAML Islands are a way to embed UWP controls in a win32 app.

So its possible we're just seeing a container, and not necessarily something that we can interact with in a traditional way.
I would like to be proven wrong though!

Edit: sorry - should've read the thread a bit closer, junkew's beaten me to it!

i'm sorry but even after read it, i don't really understand how i could use UIAutomation to handle a window... could you help me a little more please ? 🙃

"Cannot handle this ..." is the title but, what are you trying to get done ?, maybe there is a better way than what you thought of.

I'm trying to get when Task View is activated and more important, when i leave it.

[Syla]

Ok Guys, I found something who can give me what i want: 

WinGetTitle("[active]")

it gives me the title of the task view and i can test it to know when it's closed.

Thanks for you help

You could have tried faq31 with simplespy or inspect.exe to see if more is recognized.
