I am working on a parking data app using Streamlit library in python 3.7, I want to display the availability of parking spots using custom JavaScript for visualization. Is it possible to display HTML/javascript elements in streamlit web app

I have trouble understanding the first line of code inside this implementation of the bsearch function in C. I understand the search algorithm itself and I have played around with this function to get a good grasp of it but I still do not get what

Sorry I don't show my variables or anything, tried to give information only pertaining to the questions. This 1 Sub is huge.

Currently my code allows a user to select multiple files, the files selected will be sorted in a specific format, then loaded into 2 different arrays. Currently loads Columns D:E into 1 array and Columns I:K into another array (from selected files QSResultFileWS, and returns those arrays to my destination FormattingWS. I'm still trying to learn arrays so if the methodology I used to do this isn't proper, be gentle.

First time actually using anything to do with swing - sorry for the poor code and crude visuals!
Using swing for a massively over-complicated password checker school project, and when I came to loading in a JMenuBar, it doesn't render properly the first time. Once I run through one of the options first, it reloads correctly, but the first time it comes out like this: First render attempt
But after I run one of the methods, either by clicking one of the buttons that I added to check if it was just the JFrame that was broken or using one of the broken menu options, it reloads correctly, but has a little grey bar above where the JMenuBar actually renders: Post-method render

The code for the visuals is as follows:

I have the following chart that calculates premium for each month.

I am using Visual Studio code for learning python, but I am unable to use the input function (in python). All other functions work properly. I am using python 3.9.2 and I have also installed the python extension in my VS Code. Here is an image of my code.

I face that problem only when I use input function; otherwise it works properly. This problem occurred only in Visual Studio Code, while if I work on Python champ the same code works properly.

This morning I created an MSTest project in C#, and for one of the JSON resources, Visual Studio is showing this warning:

I'm retrieving the data from the API, and the image I'm getting it as a String.

In the API it shows something like this: image: "/9j/4AAQSkZJRgABAQEAYA..."

I'm using this to set it on the ImageView:

EDIT: Thank you everyone! I have never upgraded to a newer version of .NET and language version before. Thus didn't know about .csproj configuration. Even though I did a research before posting a question I was not able to find a solution myself. So, I just leave these two links for further reference, perhaps this might help someone as well.

I have upgraded to .NET 5.0.301

And finally got around to try record type in C# 9.0

I wrote a simple code but got an error during compilation.

I use Visual Studio Code as an editor.

VS Code version 1.57.0

C# extension version 1.23.12

Here is my settings.json:
