Branching Structures (If...Then & Select Case)
You'll also learn about `ElseIf` and `Else` clauses, which allow you to create complexRatingCondition structures. The guide then introduces `Select Case` statements, which provide a more readable alternative to complex `If...Then` structures.
Looping Structures (For...Next)
Next up are looping structures, which allow your code to repeat a certain block of code multiple times. The guide focuses on the `For...Next` loop, which is ideal for repeating code a specific number of times.
You'll learn how to initialize and increment loop variables, and how to use the `Step` keyword to control the increment or decrement of the loop variable. The guide also demonstrates how to use the `Exit For` statement to prematurely exit a loop.
Object-Oriented Programming (OOP)
So far, you've been learning procedural programming techniques, where your code is structured as a series of steps. Now, it's time to dive into object-oriented programming - a way of thinking that will allow you to create modular, reusable code.
The guide introduces the key concepts of OOP - classes, objects, inheritance, and polymorphism. Each concept is broken down into easy-to-understand chunks, with clear examples to illustrate their application.
Classes and Objects
In this section, you'll learn about classes - blueprints for creating objects in VB.NET. The guide explains how to declare classes and instantiates them into objects, providing clear examples to demonstrate these concepts in action.
You'll also learn about class members - the variables, methods, and events that make up a class. The guide demonstrates how to declare and use each type of class member, ensuring you understand their individual roles.
Inheritance and Polymorphism
Once you've mastered the basics of classes and objects, the guide introduces you to inheritance - a way of creating new classes based on existing ones. You'll learn how to declare base classes and derived classes, and how to use the `MyBase` and `MyClass` keywords to access members of base classes.
The guide then introduces polymorphism - a way of making objects behave differently depending on their class. You'll learn about overriding and shadowing methods, and how to use the `MustOverride` and `Overrides` keywords to implement these concepts.
By the end of this section, you'll have a solid understanding of OOP in VB.NET and be ready to create sophisticated, modular code.
Build a Simple VB.NET Application
