EAN13 | C language EAN13/UPC-A barcode generator | Barcode Processing library

Tell me how to output an image without saving it to a file? Maybe you can save it to RAM somehow? here is the form code:

Throw this program I'm trying to unzip my xml file and parse it using SAX, for the parsing part I have an exception which appeared about ClassCastException class com.sun.org.apache.xerces.internal.dom.DeferredTextImpl cannot be cast to class javax.swing.text.Element, here is my code :

I've implemented the example app from (https://cocoapods.org/pods/QRCodeReader.swift) to my own project to make a uiview on my main screen that displays a barcode scanner. I can scan a barcode and print the result, but the torchlight (flashlight) button does nothing when pressed, same with cancel and switchcamerabutton, even though the icons are displayed on the view. What could be the problem?

This is my code:

So i have a barcodescan button, I want to press it and scan an item, then retrieve the barcode and use the retrieved barcode in another button (this will send an api request with the barcode), how would i go about this?

Would love if someone could point me in the right direction, cant seem to find any answers online (probably searching for the wrong thing).

Thanks in advance!

This is partially my code:

I have two SQL functions that I want to integrate in able to make a prestashop export with a single SQL query:

Function 1 joins data from different tables.
Function 2 converts multiple rows into a single row.

I am unable to have these functions work together... Let me describe the two functions.

FUNCTION 1

I'm using Ruby for scripting, and Prawn-labels to print ISBN labels for books, using Barby to generate the EAN-13 bar codes.

The ISBNs come out of MySQL. That works fine. I can create a PDF of 30-up labels containing the titles of the books, using Prawn/labels. That works fine.

However, I am not having much joy putting a Barby-generated PNG image of the proper EAN-13 barcode on the label.

Here's getting the info out of the database and generating EAN-13, pretty straightforward:

i am stuck since a couple of days in some many2many and one2many field i am trying to add value to through code. The idea is to consume a web service to get some data from a third party website and re-use these same data in my odoo 12 modules. I was able to parse the JSON request and create entities using model.Models. However, for fields using one2many or many2many i was unable to add their values and link them to my models. Here is my python code. What i want to achieve is after the creation of a record "book.db" i want to also create its category in the same time and link it to the current record. However everytime i run the code only the "book.db" model is created. The category model is never made nor linked. Can someone point me to the right direction or correct my code if possible. Thanks alot.

I am stumbling accross large files 80.000 lines + which I do have to keep in my database. It takes like 20-30 min to push it all to my mysql database. I have a simple for loop, which just loops the whole csv.

I'm having deadlock issues with a MariaDB (10.0.27)if it's under pressure. The database schema is basically a hierarchy and the leaf node causes this:
