I am trying to separate the results of a regex query into groups. almost all the results are as I want, however in some situations I can’t capture the data correctly.

REGEX:

Platform: NodeJS

I have two roles in the nodejs project I'm having trouble inserting the result of the second function into the first function.

How to insert the result of the RUN function within the first function start (client)?

Good morning folks, I'm creating a product sales system, this topic will be a little long, because I want to explain it well.

System being developed in Vaadin + MySQL + SpringBoot + Maven

On the home screen we have the grid with the New, Change and Delete buttons:

When clicking on the new button a window opens to start "selling" the product:

The problem here is the following, when I click on “+ item” the following occurs:

Problem: a scroll bar is created (to the right of the window), the Save, Close and + Item buttons are moved down (only appearing when the scroll bar is scrolled down). Every time I try to add a product (+ item), the process is repeated, the buttons are thrown down.

Desired solution: I would like the buttons to be “frozen or fixed” at the bottom of the window, and that by adding products the scroll bar can even be created, but without moving the buttons down

I thought of something like this:

the div2 that will receive the products cannot under any circumstances invade divs1 and 3 (upper and lower)

But I confess that I was unable to create this… I tried it in many ways, but they all failed

If anyone can help me I am grateful

my code:

Good afternoon everybody.

I am creating a sales system that looks like this until now.

It shows my grid without any sales, as I am still implementing the system, we can also see the existence of 3 buttons (New, Change, Delete). So far so good.

When I click on the New button, a window opens

With the window open as shown in annex 2, we have 3 tabs (Sales, Delivery and Financial).

Each tab must have its own form and each form must have its own components (ComboBox, TextField, DatePicker ... etc)

From here I have countless problems, all caused by my lack of experience in programming, after all it's only a few months since I started learning.

My first problem:

With the current code, if I click on any of the three tabs, the same form, with the same components are displayed (see annex 3 and annex 4).

How do I ensure that each guide has its form and each form has its components?

See my code:

My challenge has been how to 01 - set Initial Inventory (considering the first day of the column); 02 - From the second day on, have Forecast (Previsão) - Sales (Vendas) = Balance. So 3 columns for each day

The way it is now, it repeats Initial Inventory throughout the days.

Here's the goal I'm trying to achieve:

Here's how the tables are related:

I am learning Ruby and when I try to create a function a problem happened.

I have 4 files: vendas.rb, pagamento.rb, frete.rb and init.rb

frete.rb

I'm trying to run this query, but it tells me this error:

42P18: could not determine data type of parameter $12

I have a table called ("Vendas2020") that has the daily sales and each row has either "C" or "V" if they're either a purchase or a sale (C/V column is the fifth one and is called "Compra / Venda"). I have inserted a function to only calculate the visible values in the table since the destination worksheet (which is a report called "Relatório") has slicers for the products, salesperson and year. The code for the sumfunction is as follows:

I'm trying to make testRigor put some data into some inputs. The thing is that it has found some of them but some it has not found.

Here I'll post an image where I show you the INPUTS testRigor has found and not found.

How can I make it found the ones I marked in red? PLease, help me.

Thanks!!!

Here is the current code (I marked the lines with *** the found and not found):
