About this ebook

This work was born from the necessity found by the author to solve various problems repeated over time, concerning the data inserted in Excel sheets in the shortest possible time. The author, being a programmer and expert in Pascal, Cobol and Javascript, searched for the most suitable solution and found it in the Excel VBA and in the Visual Studio VB. This document is intended to introduce users to programming in general and to programming in Visual Basic in particular. The VB is simple and can be used on existing csv files or data entered directly into Visual Studio, quickly processing a large amount of data. For the moment the only tool we need is Visual Studio and the csv files. Of course, I can't go into the intricacies of the databases that I will definitely include in a future book.
The book may not contain everything you should know about programming in VB, but it does point the finger at the key points to create some programs which are explained in detail in the various chapters. The content is divided into two parts one which explains programming in general and the second which explains programming in VB with concrete examples of programs.
To see the programs inserted in this document in Excel VBA, I refer you to my other eBook "PROGRAMMING IN VBA".

    PART I.: The basics of programming

    Chapter 1: Understanding and solving problems

    Understanding a problem and breaking it down into simple operations

    The first step before programming is to understand the problem to be solved with the program we are going to create.

    Just like in math, it is best to think carefully before starting to solve the problem. For example, let's assume we work in a Call Center and have all the
