Sorry, I'm using Windows 11 Pro and I have Python 3.11.8 installed.

mrob95 · 2024-02-14T17:24:25Z

Thanks for reporting. The Windows APIs that pyvda uses are not documented/stable so this happens every so often.

I haven't had the update yet but when it happens I'll see what changed and fix it, or if you'd like you can see if you can find the new interface definition. I gave some instructions for this here #15 (comment)

phpjunkie420 · 2024-02-21T17:30:48Z

I'm back to this same issue with get_apps_by_z_order.

from pyvda import get_apps_by_z_order
from win32gui import GetWindowText

for window in get_apps_by_z_order():
    print(GetWindowText(window.hwnd))

generates the exception...

_ctypes.COMError: (-2147023728, 'Element not found.', (None, None, None, 0, None))

For some reason it is having problems with pinned apps, cause this works...

from pyvda import VirtualDesktop as Desktop
from win32gui import GetWindowText

window = Desktop.current().apps_by_z_order(include_pinned = False)[0]
print(GetWindowText(window.hwnd))

Generates the title from PyCharm...

It has something to do with the last update v0.4.1 'cause v0.4.0 works just fine.

peterder72 · 2024-02-22T09:17:47Z

Also broken for me after updating at 0.4.1, albeit with a slightly different error:

NotImplementedError: Interface IVirtualDesktopManagerInternal not supported for windows version 10.0.22621, platform version 10.0.22621. Please open an issue at /~https://github.com/mrob95/pyvda/issues.

I didn't yet run the tool to fetch the GUIDs on my machine, but maybe the dumps found here could help

mrob95 · 2024-02-22T17:47:56Z

Thanks for the reports. I'll work on this this weekend. The version/build numbers reported by windows are sufficiently unreliable that I think it will be better to just try all of the interfaces and see whether one works, which seems to be what Microsoft recommend doing.

Also, for people feeling like contributing:

mrob95 · 2024-02-25T15:54:35Z

@peterder72 @phpjunkie420 @stdedos I have just pushed a big change. It would be great if you could run the tests on the master branch on your machines and see whether it makes things better, worse, or no change. I'll test on an up-to-date win11 laptop tomorrow.

Unfortunately, I can do it late tomorrow the earliest

That's fine, no rush, any testing is appreciated 👍

I looked at the releases and it shows 0.4.1 which is the release that generated the exception I posted.

peterder72 · 2024-02-25T19:40:12Z

@mrob95 I seem to be still having the same issue with the new master, I'll try getting the exact interface UUID tomorrow

mrob95 · 2024-02-25T19:52:04Z

@mrob95 I seem to be still having the same issue with the new master, I'll try getting the exact interface UUID tomorrow

Thanks, any information you could give would be great - has it worked on a previous version of pyvda? Theoretically nothing should have changed relating to version 10.0.22621

I don't know what changed from 0.4.0 to 0.4.1, 'case 0.4.0 works just fine. I did a bit of testing to figure out the source of the problem and it has something to do with pinned apps.

phpjunkie420 · 2024-02-25T20:27:59Z

I use a custom start menu on all of my computers, and a hacked taskbar to revert back to the kinda classic taskbar on windows 11 so I'm not sure of what a pinned app is: if it is 'pin to taskbar,' like the old school quick launch apps on the taskbar, which is what I'm using, or if it is the 'pin to start' on the start menu itself.

My next comment is off topic. I think that the windows start menu, from windows 11 all the way down to windows vista, and the taskbar in windows 11 is junk ass bull****. I really can't see why they would lock the height of the taskbar or make it less customizable. I don't like combined grouping of apps, and I like being able to see the titles of the apps on my taskbar.

peterder72 · 2024-02-26T08:05:19Z

@mrob95 Everything worked for a long time before, I think I was even on 0.3.X earlier. After a Windows update all my pyvda scripts started crashing, an update to 0.4.1 also didn't help

peterder72 · 2024-02-26T08:20:52Z

@mrob95 Just checked, now makes sense why the fix doesn't work. The interface is not there at all...

stdedos · 2024-02-26T08:41:56Z

Sorry for the tangent: @phpjunkie420, what are those widgets top-right? 🤩

stdedos · 2024-02-26T08:49:13Z

On the matter-at-hand: If you really go the https://learn.microsoft.com/en-us/windows/win32/api/sysinfoapi/nf-sysinfoapi-getversionexw#remarks avenue, I think you need to re-wire the library 😅

Create a class that is able to do everything
Probe-for-config, and instantiate the interfaces "as available"
When users probe for a functionality, accept / throw NotImplementedError as available.
1. ... hopefully allow the lib-users to handle "such a situation" gracefully (via a strict=True, or graceful=True)
Attempt to be helpful to everyone:
1. "Feature VirtualDesktop.name is not supported in $winver. Cause: GUID a-b-c-d is not available."
2. OleView is an amazing tool. But if you could implement a utils-class-func to search for "known GUID names" (e.g. IVirtualDesktop*), and print their associated GUID keys for debugging.

peterder72 · 2024-02-26T15:54:12Z

Alright, so I've looked into it a bit.

Apparently I was blind yesterday, and the error I got was about IVirtualDesktopManagerInternal2, not IVirtualDesktopManagerInternal, which actually succeeded after the latest fix. It also turned out I don't have any names associated with my COM interfaces anymore (or OleView doesn't show them on Windows 11, also possible), so I have to only deal with GUIDs, which is why I couldn't find anything in the screenshot I posted above.

I did some manual digging, and found the missing GUID for IVirtualDesktopManagerInternal2: 53F5CA0B-158F-4124-900C-057158060B27.

Manually changing the GUID in the library fixed all issues on my machine. The GUID seems to match with this dump

downgrade to 0.4.0

pip install pyvda==0.4.0

On the latest master branch are you able to import the library at all? Could you run with debug logging enabled up until it fails and post the output?

Thank you. I think it was matching on the error message that was the problem, I have merged a fix.

mrob95 · 2024-02-26T22:39:34Z

On the matter-at-hand: If you really go the https://learn.microsoft.com/en-us/windows/win32/api/sysinfoapi/nf-sysinfoapi-getversionexw#remarks avenue, I think you need to re-wire the library 😅

Create a class that is able to do everything

Probe-for-config, and instantiate the interfaces "as available"

When users probe for a functionality, accept / throw NotImplementedError as available.

... hopefully allow the lib-users to handle "such a situation" gracefully (via a strict=True, or graceful=True)

Attempt to be helpful to everyone:

"Feature VirtualDesktop.name is not supported in $winver. Cause: GUID a-b-c-d is not available."

OleView is an amazing tool. But if you could implement a utils-class-func to search for "known GUID names" (e.g. IVirtualDesktop*), and print their associated GUID keys for debugging.

I started trying to implement it this way the other day. The problem is that we need to know what all the interfaces are when we define them, to be able to set the return values and arguments correctly. We can't just say 'GetCurrentDesktop returns an IVirtualDesktop, but we don't know which one yet', we need to know. Doing the feature detection once at start-up seems like at least a not-terrible option, and should be robust once these issues are worked through. Not having a way of testing any of this in CI across all of the Windows versions makes me reluctant to do big refactors.

We can't just say 'GetCurrentDesktop returns an IVirtualDesktop, but we don't know which one yet', we need to know

You can return ... a union? 😅 I know it's not optimal, but if "all of those" return a thing that responds to e.g. .name and .rename(), then it's good enough for static analysis?

Not having a way of testing any of this in CI across all of the Windows versions makes me reluctant to do big refactors.

Yea, it sucks 😅 But hey, we/I am here 🙃

So far, you have a test harness that "I did not believe it was working on Windows".
I'm star-struck to see how well it works.

Sorry for the tangent: @phpjunkie420, what are those widgets top-right? 🤩
Rainmeter, desktop customization tool kinda like conky for linux.

This is the skin I'm using. Gadgets: Gadgets for Rainmeter

Reproduced this and merged a fix, thanks.

I've just released 0.4.3. I'm aware of an issue on the latest version of Windows 11 where set_focus returns a permission error, but otherwise I think everything should be working on all supported versions. Please let me know if not.
