AutoScroll | For users on Linux or Mac , the lack of autoscroll can be | JSON Processing library

I'm attempting to create a dynamic panel where I can add controls to and scroll when the controls are off the panel's height, while also hiding the scrollbars.

I'm using a FlowLayoutPanel and I'm constantly adding custom panels to it, with their Width set to the parent Container's Width.
I've also set its AutoScroll property to true.

However, one problem remains. How do I hide the darn Scrollbars? Both of them.

I've tried the following:

So i have this nodejs that was originaly used as api to crawl data using puppeteer from a website based on a schedule, now to check if there is a schedule i used a function that link to a model query and check if there are any schedule at the moment. It seems to work and i get the data, but when i was crawling the second article and the next there is always this error UnhandledPromiseRejectionWarning: Error: Request is already handled! and followed by UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). and it seems to take a lot of resource from the cpu and memory. So my question is, is there any blocking in my code or anything that could have done better.

this is my server.js

How to customize CSS in order to force dataview (Ext.view.View - classic toolkit) item to be equaly distributed in vertical direction. I have dataview that I would like to present in two columns, but items are not of the same height. I would like to distribute them evenly in vertical direction. Since a picture is worth a thousand words, here is the picture of what i get and what I would like to achieve:

So, dataview aligns items vertically, but I would like that item 3 starts just below the item 1. Basically, I would like that items are poopulated orderly one below the other. I would also like to avoid having two dataviews (one for the left part and the other for right part).

Here is what I got so far:

I'm, facing a very simple and well known problem. I have a treeview in my UWP application, a User can reorder items by drag&drop with a few restrictions. The d&d itself works like expected, but now, when i have a very long list of sub-items to drag to a place very high or low in the tree, i need to have an autoscroll like every user knows from the windows explorer for example, moving the cursor down to bottom activates a scroll... but... how to implement that in UWP? Is there any default property I'm missing? Or how can i even scroll to a specific node in the tree? There are tons of info for Winform or even WPF, but i'm stuck on UWP and was unable to convert a WPF solution to my app.

Does anybody have any hint on that problem?

Edit: here is a shortened version of my XAML:

I create a class to design a dynamic TableLayoutPanel but during the rendering the table behaves badly. This is the class:

I am mostly done creating a GUI that will pop up with an image in a picturebox, and allow the user to draw multiple red circles on it by clicking (where I'll then have it save to a passed filepath/name).

User draws the circle by clicking where on the image they want the top left starting point to be, and dragging to resize it (where the previous circle disappears and the correctly sized one is displayed) until they release the mouse.

The first circle appears correctly, but for all following circles it does not refresh properly and thus rather than resizing one circle dragging the mouse displays a bunch of different sized circles corresponding to all the past dragged mouse positions.

I have been banging my head on this one all day, what am I missing that will make the follow-up circles display correctly?

I am writing a small application based on tkinter in order to read serial data from my arduino. The arduino, when it receives a serial text (rf), it will begin sending data to the pc.

Below is the suspicious code:

I have a fetch get request that parse page and get some parametrs to generate new url and insert it into input fields
I have multiple values from value1, value2, value3
The question is that how i can generate multiple urls from this parametrs and insert it into fields(fields should generate dynamically)?
Now, window with form dont generates

If i put break into loop, code generate window with form but show only one url

As a result of this code should be Window with form and three input fields with urls

i have a chatwidget which scrolls automatically if a new message comes in vertical to the bottom but not on mobile iOS Safari. The Scroll down code is this:
