Introduction to Visual Basic (VB)

Programming Fundamentals

• BASIC stands for Beginner's All-purpose Symbolic Instruction Code.

Visual Basic

• Visual Basic was developed by Microsoft to create applications for Windows operating systems.

Programming Concepts

• Visual Basic introduced the concept of event-driven programming in which programs respond to user interactions.
• A GUI (Graphical User Interface) in computing allows users to interact with a program using visual elements such as buttons, menus, and windows.

Visual Basic Controls

• In Visual Basic, a 'control' is a graphical element, such as a button or text box, that users interact with to provide input or receive output.

Programming Paradigms

• Event-driven programs in Visual Basic differ from procedural programs in that they respond to user interactions, whereas procedural programs execute a sequence of instructions.
• A method in a program is a block of code that performs a specific task.

Object-Oriented Programming

• Inheritance in object-oriented programming allows a new class to inherit the properties and behavior of an existing class.
• Encapsulation in programming refers to the bundling of data and methods that operate on that data within a single unit, such as a class or object.

Program Execution

• Properties are typically set in a program when an object is created or when the user interacts with the program.
• An event procedure is a block of code that is executed in response to a user interaction, such as a button click.
• A program statement is a single instruction that is executed by the program, such as assigning a value to a variable.
