Mostly out of curiosity, i was wondering how should i approach this. I'd like to make it so that when i turn off my screen, the computer shuts down. In essence, i'd like to make a service that constantly check whether the screen is on or off.
Any ideas/suggestions are welcome. Thank you for taking the time and i wish you all a plesant day.
Well, if there would be a way to check the status of the connected monitors and you shut your computer down when the screen goes off, how do you plan to turn your computer on again? I expect then you have to use the normal hardware button on your tower. Why not stick to these buttons? It has worked the last 30 years or so...
To make an actual suggestion:
Setup a webcam to monitor your screen. Using simple picture analysis you can detect if the screen is on or off
Shutdown your computer down when screen goes off
Also you can monitor the szenario when turning your screen on. You should see a manufacturers logo for a few seconds or somethinglike this. (Now you need a second computer with a second webcam)
With the second computer you can build some little machine that pushes the power on button on your first computer to turn it on
But how to turn on/off the second computer? Well, you need another one for that...

I recently played a game called "Quake Champions" from Steam. Against a player I know for a fact is a cheater, my left mouse button stopped to work whenever he was in a close-radius.
I am sure it is a cheat because my mouse works just fine on other computers.
I heard of DLL injection and cheaters using such methods. I am afraid somehow my mouse and maybe keyboard are being monitored remotely.
What can I do to find out, and also solve the issue ?
I tried re-installing display drivers, full game and deleted all files, mouse driver and app (mouse is Razer Basilisk Essential), I tried anti-malware softwares, etc.
Now even outside of the game the mouse seems to skip clicks at times, especially when I hold and drag (continuous fire in the game...).
I documented myself a bit and heard of hooks. I would ideally like to figure out which process (visible or not in task manager) hooks or interacts with both my keyboard and mouse, it would probably be a great way to figure out if I am in trouble or not.
Formatting the computer in full IS an option, but one I would prefer to avoid as I have costly licenses that I may lose, due to a limited number of activations...
Any help appreciated.
Further info:
Razer Central/Synapse -> Keyboard: Razer Cynosa Chroma ; Mouse: Razer Basilisk Essential
Further anxiety:
Shortly after this event happened, I received an alert from my Facebook saying somebody tried to log in... It was not me. It may be a coincidence, it may not. Fortunately my Facebook password is strong enough. But this is further reasons to be anxious on my end...
I'm wondering if there's a good way to automate changing my display configuration in Windows 10?
I have 3 monitors attached, and I find myself wanting to configure my system in one of 3 ways:
All monitors set up to extend the desktop.
Only my central (largest) monitor enabled, others both disabled.
Only my right-most monitor enabled, others both disabled (I think hook up a spare HDMI cable on my center monitor to my laptop, and the monitor automatically switches to that input).
Manually, this involves opening the Display Settings panel, selecting the monitors, and either marking them as "Disconnected" or "Extend desktop on this display".
Is there some nice, scripting-friendly way to do this? I'm more comfortable doing this sorta thing on Linux, where I'd whip up a quick shell script to call the xrandr command a few times, or something like that...
I have a problem - when accidentally launching any of native Windows apps and alt-tabbing to normal ones, then I have a hint (that occupies a fair quarter of the screen), that I can swipe between apps (screenshot is in Russian, but that's what it says).
The things is that I know for sure that my display is not a touch-screen, so how can I persuade Windows into believing that?
At the moment I have to reboot every time I got it (couldn't find any related process in the task manager to kill).
Thanks.
Actually a reply by #David.
You can move mouse to the upper left corner [to switch between apps], but also makes the swipe hint to hide.
Thanks, #David!

And then I've a small question: how to turn off this program completely?
I tried: BackgroundAudioPlayer.Instance.Close();
but it stills running. I wanna remove this control when program is turned off.
See this picture. thanks so much :)
BackgroundAudioPlayer.Instance.Stop() ?
Also, this 3 part series is really good.
I use BackgroundAudioPlayer.Instance.Close() and the agent is shut down
Closes the player and removes all resources reserved for it, including
the current AudioTrack.
You can see the Shut down event is fired in OnPlayStateChanged event handler
Also, when seeing at the Output window, the Background Task is terminated
I've noticed that the running times of my CUDA kernels are almost tripled the moment the screensaver kicks in. This happens even if it's the blank screensaver.
Oddly enough, this appears to have nothing to do with the power settings. When I disable the screen saver and let the screen power off, the performance stays the same. When I set the "Turn off monitor" to "Never" and lets the screen saver kick in, it happens.
Why does this happen?
Is there a way to counteract this phenomena?
Is there a way to tell windows not to kick in the screen saver? (How do media players do it?)
I'm working on XP SP2 x64
Firstly, its interesting that CUDA is so impacted.
But here is the recipe in win32 for avoiding the screensaver kicking in:
A normal approach is to send yourself 'fake' key presses occasionally using the SendInput API, to reset the inactivity timer that triggers the screensaver.
It is possible to stop applications doing this, however, using the SPI_SETBLOCKSENDINPUTRESETS parameter for SystemParametersInfo.
Another approach is just to turn the screensaver off programmatically, using SPI_SETSCREENSAVEACTIVE for SystemParametersInfo. However, this is a global setting for the whole user - what if two programs use this overlapping? Try to avoid this!
