ui2 | UI module to provide extra functionality | Animation library

I'm having an odd issue. I have uid and ui2 columns that I combine into a key column. Most of the time the uids are an alphanumeric combination and I don't have any issues.

However this set of data the uids are all numeric:

Input data:

I have tried to write an if/else statement check if the 2 lists I'm working with don't share any values. If they don't, I want to return an empty list. I can't work out how. Whenever I add in the statement if messes up my code to print inside the function and prints it the about of times a list item was entered or says invalid syntax.

The program is supposed to compare 2 lists, only print out the numbers they share in the list, only print single numbers if they repeat. If an empty string is entered, exit the program. If the lists don't share numbers print an empty list e.g Output: [] This is what I have so far. Should I also be using a return statement instead of print?

I need to align button's text, horizontally left on C# WinForms application. All the buttons create dynamically. I tried few ways as bellow. But not worked.

I want to create a container image of my Angular 12 application with the Paketo buildpack for nodejs. I created the application via Angular CLI and coded it away until now I want to deploy it.

I created a simple survey form in R Shiny (see code underneath). Now I would like to add some functionality that requires input on all questions on a specific page, before the 'Next' button works. So, if you press 'next' on the first page, but have not answered the first three questions, an alert/error message must appear. The same goes for the second, third, fourth page etc. This example has a few questions, but my final questionnaire would have around 15-20 questions.

It would be great if someone could help me out!

I'm building an app I want it to have a very simple walk-through/on-boarding experience which shows some messages indicating the functionality of every item on screen. The messages must have a next button that shows the next message and close the former one.

something like this:

I've been looking on many onboarding widgets but none of them allow me to present something like I described, So I figured I could make it by using AlertDialog on the app UI.

I want it to execute automatically as soon as the screen is loaded so I have this in the initstate:

I have a DB that is structured like this:

Apologies if this question had been asked before (it probably did). I never used SQL before and the answers I've got only got me more confused.

I need to find out if an ID exists on different tables and get the total number from all tables.

Here is my query:

I am trying to make Datagridview paging, I have already performed the paging and it works fine, the problem is when I try to search for records from the database the problem is that Datagridview doesn't change and the data returned from the database is not showing and the pages count keeps increasing on each search.
