How does Zoom Attendee Attention Tracking (Window Focus Tracking) work? - window

I just heard about this feature on Zoom Meeting and found it a bit puzzling. Do any of you guys have thoughts on how exactly this would work? It seems like window focus isn't something that should be shared by default. Also, it says that the feature only works in their desktop client on windows / mac, so is installation writing some registry changes? If so, any insight on how it works and why it doesn't work on linux?

Native Windows: How to capture windows that are covered by other windows like Google Hangouts does

I'm working on a feature that allows users to capture windows and stream them. Using native windows api calls, I'm able to get a windows location and capture it.
BUT, if there is a window over it... I'm not able to capture that blocked portion and I just replace that area with gray.
SOMEHOW... google chrome, a non-microsoft app... figured out how to capture a window while it's behind other windows. Skype for Business, a Microsoft product, can't even do that.
Has anyone worked on something like this before? If so, a point in the right direction would be extremely appreciated.
Thanks!

How can I lock down a Mac to exhibit one website?

I'm currently working on a website that will be in an exhibition soon. Users will have a keyboard and mouse in front of them, so I need to lock down the machine to be restricted to just one website. Guided Access mode on iOS is a perfect example. I wish Apple had an OS X version for this reason.
I'm currently trying parental controls but it seems to be quite buggy/not responding to my preferences. I'd really love to just have Chrome or Safari locked to fullscreen somehow so users can't exit the browser/redirect to another website.
Thank you in advance!
I'm thinking you could put Chrome in kiosk mode(can't change website) then change the shortcut keys for exiting out of fullscreen mode if you can on a Mac, and maybe having another desktop and monitor for emergencies. I would have made this a comment but I can't :P This isn't really an answer, just a suggestion. It would really be easier on another OS to do the stuff above.
Recently used 'Web Kiosk' software for exactly this purpose: https://www.macproline.com/webkiosk
It has a lot of options for locking down the machine, both in terms of web sites visited, and disabling key commands, preferences, switching apps, quitting apps, etc.
When searching for a solution for this, I was surprised how few options there were. That said, I would give this a look.

Automated web interface testing and locked screens

I'm using my desktop to automate getting files from a site using RAutomation and Watir. I couldn't find anything on how RAutomation works with a locked screen if at all. There might be better ways to do this but I'm now more interested in knowing if it's possible to automate sending keys through RAutomation still works or it doesn't just because of the locked screen.
No, it is not possible to interact with the windows and their controls when the screen has been locked. It is a security feature of Windows.
However, you could do something through Remote Desktop. Maybe the discussion at this issue might help you:

Night mode and Microsoft's submission requirements

I heard that Microsoft refuse app's which unreadable in the "night mode" whatever it is? I mean when the phone goes into night mode all the color fonts are changed and that makes app unusable, then they reject the app.
I nave to submit RSS app and I do not know even what I have to watch out about that night mode. Please introduce me.
I suspect that what you mean is "light theme" mode. There are a lot of useful comments about this on this other thread. Windows Phone 7.1 Light/Dark themes management.
From my own personal experience, this is a bit of a headache. If your app isn't very stylistic, try to use the built-in colours for all your controls and whatever you do don't put an image background on it (that was my downfall).

Screensaver to cycle through webpages?

Does anyone have any suggestions for how to create a screensaver that can cycle through some webpages? I would like to create a screensaver that displays various dashboard and statistics pages that are available in our Hudson CI server. This is a windows machine, with firefox and IE available.
Extra bonus points if I can do it in ruby! :-)
Cheers,
Mike
I programmed a lot of screensavers in Delphi, but I think the following should be applicable to all sorts of development environments.
You create the main form of your screensaver and put an IE-control on it (or if your development environment does not support it, an OLE-container) and then create a timer which changes the webpage shown by the IE-control.
Sorry no solution in ruby....
Ok, so after a few false starts I found a pretty simple solution. I used Visual Studio Express Edition to create a windows forms application. You just need to drag a WebBrowser control onto the form and resize to full screen at startup. Then all you have to do is hook up the event handlers to deal with the mouse and keyboard.
Some more details here:
