Introduction

In 1995 Microsoft released Windows 95 and Visual Basic 4.0. Many US immigrants rushed to learn Visual Basic to become computer programmers. At that time I worked as a lab tech in a small laboratory on Flatbush Avenue in Brooklyn NY.

My wife keep telling me,

- Learn programming! You will earn good money!

- But I am biologist, - I argued.- I have no idea what programming is!

- Former musicians and housewives are learning programming! Come on! – argued my wife.

I registered in a private computer school in Brooklyn and started to learn Visual Basic.

Classes were three or four times a week during six months. I liked it. It was easy!

In eight months, I took Microsoft Certified Exam in Visual Basic 4.0 and passed it. My former teacher invited me to his school to teach Visual Basic. It was fun.

I liked programming so much that I continued my education in Borough of Manhattan community college where I learned 3 more computer languages: C++, Assembly and Java.

Visual Basic is one of the easiest to learn programming language and yet it is very powerful.

You do not have to be a geek, to understand it. One of my students did not know how to use computer, but after one year of learning Visual Basic he found job as computer programmer.

Of cause, I do not promise that after reading my tutorial you will become a professional, but I promise that you will be able to continue learning Visual Basic on your own.

You can download from my website 7 working VB projects: Hello World, Variable Scope,  Checkers Game, Using Windows API, A Password Keeper, A Patient management application and A Billing Management application.             

The Password keeper application allows you to store any number of passwords that you do not need to remember anymore.
