Chapter 1

Welcome to Visual Basic Programming

Visual Basic (VB) is a high-level programming language developed by Microsoft. It is known for its ease of use and rapid application development (RAD) capabilities, allowing developers to create applications with a graphical user interface (GUI) more efficiently. VB evolved from BASIC (Beginner's All-purpose Symbolic Instruction Code), one of the earliest programming languages designed to be simple enough for beginners to learn.

Key Features of Visual Basic:

Event-Driven Programming: VB is designed to handle events, such as user actions (mouse clicks, key presses), making it ideal for developing Windows applications.

Integrated Development Environment (IDE): VB comes with a powerful IDE that includes tools for designing forms, writing code, and debugging.

Extensive Libraries: It provides a rich set of libraries and controls, allowing developers to add complex functionality with minimal
