Study Notes

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.
