Python module for manipulating Windows 10/11 windows and virtual desktops.

pyvda's Issues

Add support for Change Virtual Desktop Background on Windows 11

Interfaces for this are available on Windows 11. I've added the interface definitions for these functions to https://github.com/mrob95/pyvda/blob/master/pyvda/com_defns.py#L216-L220 but have not linked these up to the VirtualDesktop class.

I don't have access to a Windows 11 machine atm, so if someone is on Windows 11 and can make a PR for a set_wallpaper method that would be great. It should raise an error if BUILD_OVER_21313 is not True.

Windows 11 22H2 - Exception when calling get_virtual_desktops

Attempting to call get_virtual_desktops() on my Windows 11 22H2 (build 22621.1) machine throws this error:
_ctypes.COMError: (-2147023116, 'A null reference pointer was passed to the stub.', (None, None, None, 0, None))

Windows update KB5034765 completely broke pyvda

Expanding on Features available

This is not technically an issue, but an idea/request.

Would like to be able to do the following:
Get Virtual Desktop Name
Change Virtual Desktop Name
Change Virtual Desktop Background
Create New Virtual Desktop
Delete Virtual Desktop

I've seen this option in C# but would love to be able to use it within your module

Reordering desktops on Windows 10 build 19044

The desktops reordering feature was made available in the latest Win10 builds (starting from Windows 10 build 21337).

Is it possible to implement it somehow programmatically on a Win10 build without native support, particularly 19044 ?

'No such interface supported' after minor Windows update

After the latest minor Windows update I performed, pyvda suddenly fails directly on import (from pyvda import VirtualDesktop).

Platform version: 10.0.22621

Error log:

Support for `10.0.18363.836`

The error encountered is the same as #33.

I am using https://github.com/sdias/win-10-virtual-desktop-enhancer - which already includes a .dll ready-to-go.

However, even the "suggestion for the source" (https://github.com/Ciantic/VirtualDesktopAccessor/; assuming https://github.com/Ciantic/VirtualDesktopAccessor/tree/2019-windows10 given that the rest are win-11 code), looks like it has the exact same GUIDs.

Support getting HWND from window title

I think it would be helpful to add a way of getting a window's HWND from it's title, so that it can be used to automate moving windows in more scenarios.

I currently implemented this as follows:

def move_window_by_name(hwnd, l_param):
    if win32gui.IsWindowVisible(hwnd):
        if 'Window Title' in win32gui.GetWindowText(hwnd):
            AppView(hwnd).move(VirtualDesktop(2))

win32gui.EnumWindows(move_window_by_name, None)

I'm sure there's a way to add this into the main module, I just didn't look into it.
Or, at least maybe put this code in the README in case anyone else wants it.

VirtualDesktop go method throws COMError

Traceback (most recent call last):
  File "C:\Users\Me\AppData\Local\Programs\Python\Python310\lib\site-packages\pyvda\pyvda.py", line 375, in go
    managers.manager_internal.SwitchDesktop(*NULL_IF_OVER_20231, self._virtual_desktop)
_ctypes.COMError: (-2147024809, 'The parameter is incorrect.', (None, None, None, 0, None))

Haven't been able to thoroughly test this but figured I should make an issue on the off chance that someone knows what's going on. This is version 0.3.0 on Windows 11 so I'm aware you might not have a machine that runs that.

_ctypes.COMError

I used getattr in window.hwnd to see if the window has been closed. I did this to see if it would generate an exception and it did. The exception was _ctypes.COMError. I've tried to find this in pyvda and the required packages (comtypes, pywin32) but I've been unable to find it. I want to import it so I can contextlib.suppress the exception.

permission problem

I have a few questions to consider:
1、How do I set permissions on virtual desktops
2、I want to hide the virtual desktop taskbar window

However the build version BUILD_OVER_21313 is being skipped and it makes it down to the if statement.

pyvda/pyvda/com_defns.py

Line 244 in 2b8eaaf

else:

The root analysis is sys.getwindowsversion().build is reporting 9200 on my machine.

However running the above code through the interpreter:

>>> import sys
>>> sys.getwindowsversion().build
22000

So I'm left scratching my head a little bit on this one that it could be Natlink related.

OSError: [WinError -2147221008] CoInitialize has not been called

CoInitialize() must be added to _get_object in utils.py or else it will throw the above error. This took me a while to figure out, as i kept trying to fix it by calling CoInitialize() from my own script, to no avail.

How can I write a module simlilar to this?

Thanks for the work done in building a wrapper for the virtualdesktopmanager class. Absolutely brilliant. But I will like to have the experience to write this on my own and have some hands on experience building the wrapper from the groundwork. Just to fill my curiosity. Any reference will be helpful

nice job!it works

nice job!it works.thanks

having the same issue as @nanosil in this issue post #33, i compiled my script with pyvda in it and have it to startup with my pc and running into this traceback error

running the script non compiled runs into same issue, the compiled script was running fine for about a month before this issue and was running fine yesterday and currently runs fine on another pc, running windows 11 2h22 and just upgraded to 2h23 to see if it would help with the issue but does not work on either version, running python 3.11.5 and pyvda 0.3.2

Is there any chance that pyvda be updated for windows 11?

Is there any chance this can be updated for windows 11?

My installation of windows 11 is modified. I'm also using python 3.11.7, cause pyvda doesn't work with python 3.12.

I've been able to get pyvda to work on windows 11.

Anyway, can you update pyvda to work with windows 11?

Add some small utility functions

I know it's not the scope of your tool, but it'd be nice if AppView had a .name.

It is not complicated either:

   ...: from win32gui import GetWindowText
   
In [2]:print(GetWindowText(get_apps_by_z_order()[0]))
IPython: E:pyvda/pyvda

... or you can choose to do some comtypes etc.

It would facilitate e.g. on the #44 debug

When changing desktops, the desktop icons become absolutely humongous.

When the Virtualdesktop().go() is used to go to a desktop, the Windows desktop icons become super big.
