CyberSecurity | A curriculum for a high school cyber security course | Learning library

So I have the following code, where I'm fetching data to be rendered in my component. However, if the useEffect is set to run once, it wont render the data inside the component, and having it constantly running is not sustainable.

I am developing a little website project for a cybersecurity course. What is the best practice for utilizing mysqli_real_connect on a PHP document?

Is writing the db credentials directly as arguments of the function a good way to go or should I pass them in a different way?

P.S. The user can't see the source code, but I am trying to see if there are security aspects which I am overlooking.

I am having trouble writing my json data to a google sheet - I get the exception "The number of rows in the data does not match the number of rows in the range."

I think the problem is with how the range is set - but I don't know how to fix it. I include a sample of the json data after this script:

I created a program in vs, alongside with some batch files. The Batch files run great by themselves and through the debug/release when including them in the folder with the .exe.

My problem is I want to be able to ONLY have the .exe file from my release and it still work.

Is there a way i can build these files inside the .exe? I have tried using c# to write my console commands instead of including seperate batch files. But im pretty new to c# and i get nothing but errors with the commands i want to run/if i run to many lines.

I would much rather have just c# instead of including the batch files but that I can't seem to figure out a solution to either.

Any help would be appreciated.

This is me currently calling batch files which works just fine. Again, if there is a way to just write this in c# instead of calling a batch file I would be happy to learn.

I have a tabbed slider that's supposed to change the color of the active tab. The tabs switch properly, but for some reason, I can't get it to change the active class over. Below is the HTML and JS.

I know I'm calling something improperly to make the classes switch in the tabs, but I'm not sure what it should be

I'm trying to display a data set using the DT package for R which lets you render javascript datatables. Two of the columns contain text that is quite long so my colleague wrote some JS to truncate the text while letting you see the whole text when you hover over the cell. We also want the user to be able hit a download button what the filter. BUT, when I add the code to make download buttons, it breaks the text truncation. I'd like to have someway to truncate the text AND download the data.

Here's the function:

In the middle of creating one of my first webpages for a college course and ran into a really weird problem. I've been commenting out code trying to find where the issue is but I have no idea what's wrong.

I used *{ border: 1px solid red; } to see all the CSS elements, and all I see that's related is a red line that outlines the entire page.

Any help? Here's my CSS.

I have a form with a select element

I'm trying to compile a simple "Hello World!" code, but it seems not to be working. I uninstalled the anti-virus "ESET Cybersecurity Pro" on my computer, and it still didn't help. It is really an issue for me to run my codes.
