screentime | Measure how much time things | Frontend Framework library

While working on a react native project I stumbled upon this error:

JSON value of "90vh" of type NSString cannot be converted to a ABI44_0_0YGValue. Did you forget the % or pt suffix?

What does ABI44_0_0YGValue mean? I have tried the pt suffix but the same error still appears. What could be the problem?

I am using styled components to add the width and height value to different elements:

I have an application that keeps tracks of other applications screentime. I have a service which is supposed to give a notification after the user has spend X time on a specific application. To keep track of other applications, I have used a Service. When my own application is open, the details of other applications screen time is shown correctly, but when my app goes in the background, the details aren't updated (they remain the same as when my own application was open), but as soon as I reopen my application, the details get updated. Why isnt the UsageStatsManager working properly while being in the background?

i'm making a basic timer, is one of my first projects, when you press a button the code should create 3 different variables that obtain the values from their respective inputs, this 3 symbolize hours, minutes and seconds.

what happens is that if you console.log any of this 3 variables you get that is undefined for some reason, if you don't have this values the entire countdown will not work.

the inputs are set to start at value = 0 in the html, so it's supposed to at least return 0, not undefined

I am a newbie to C++ and wanted to create a Screentime application like in ios for windows. But unfortunately, I am stuck after creating the default bootstrap by using visual studio 2019. Can anyone suggest to me what I should do next and other related resources? I just wanted to create a simple app (let's say screentime) that monitors other apps active and focused state whenever the screentime app is run and store the app name, start time and end time in a text file.

I want to completely empty a JSON file, while still keeping the file. How do I do that? I tried:

I have some animation code that changes background color infinitely

but the problem is I want to do this without a button trigger

and I want this to be automated at first time (when it's firstly loading)

below is code

I`m so stuck could anyone help please

the purpose is to animate without a trigger, it automatically runs animation that changes background

So I added a calendar to react which changes the workout data to a specific date. When I change the date the data does change correctly. If I refresh the react web pages I get the updated data. I'm just a little confused on how to have node js initiate the data update in react. After changing the data I have node emitting to this socket...

My widget looks like this

I am currently making an app that tracks users time in windows like togglDisktop app https://toggl.com/ but more advanced with a dashboard, where you can see apps usage automatically without starting a watch, like this

what is note good in this app is that you need always to start a timer which we always forget to do,

I have no idea about how to do it,

I have searched for hours about the class that tracks the user in the windows like the screentime in the iPhone an found nothing, like in this image https://images.app.goo.gl/bGUA9Ei9FtuzzEEf7

I have found something like GetForegroundWindow function but I don't think that it can track the background apps too, its only for the focused app https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getforegroundwindow
