Related introduction:

Visual Basic (referred to as VB) is a general-purpose programming language developed by Microsoft The object-based programming language is a visual programming language that is structured, modular, object-oriented, and includes an event-driven mechanism to assist in the development environment. It is a language that can be used for Microsoft's own product development.

In Visual Basic, properties, methods, and events can be used to describe and measure the characteristics of an object.

1. Event

An event refers to something that happens to a certain object. Events can be divided into mouse events and keyboard events. For example, mouse events such as mouse click (Click), mouse move (Mouse Move), mouse down (Mouse Down), etc. may occur on the object of Command Button, and keyboard press (Key Down) may also occur. Wait for keyboard events.

The event specifies the object's "under what circumstances?" and is often used to define the timing and conditions for an object to undergo a certain reaction.

2. Method

Methods are internal programs used to control the functions and operations of objects. For example, people have functions such as talking, walking, learning, and sleeping. In Visual Basic, these functions and operations provided by objects are called "methods." Take a form as an example, it has methods to show or hide.

The method specifies "what can the object do?" and is often used to define the functions and operations of the object.

3. Properties

Properties refer to some indicators used to describe the name, position, color, font and other characteristics of the object. You can change the characteristics of an object through properties.

Some properties can be set through the properties window at design time without writing any code; while some properties must be set while running the program by writing code. Properties whose values ​​can be read and set at runtime become read-write properties, and properties that can only be read become read-only properties.

Attributes specify "what does the object look like?" and are often used to define the appearance of the object.
