Lesson 1: Introduction to Visual Basic 6

Learn the fundamentals of VB6 programming and create your first applications

Key Takeaway

Visual Basic 6 (VB6) is a classic event-driven programming language for creating Windows applications. Despite being discontinued, it remains valuable for learning programming fundamentals and maintaining legacy systems.

Welcome to Lesson 1 of our Visual Basic 6 (VB6) Tutorial! This lesson provides a clear introduction to VB6—Microsoft's popular event-driven programming language for creating Windows-based applications. This is your starting point to learn how to build interactive and professional-looking software.

What is Visual Basic 6?

Visual Basic 6 (VB6) is a legacy programming language developed by Microsoft. It enables developers to create Windows-based applications using a visual interface and event-driven code. Despite being discontinued, it is still used for maintaining older systems and is a great starting point for programming concepts.

Why Learn Visual Basic 6?

Beginner-Friendly

Easy to understand with straightforward syntax and visual development environment

Industry Relevance

Widely used in legacy systems across industries

Fundamental Concepts

Teaches core programming principles: loops, variables, functions, etc.

Rapid Development

Quickly build Windows desktop apps with GUI components

Getting Started with the VB6 IDE

Once you install VB6, you'll be greeted with the Integrated Development Environment (IDE), as shown below. This is where you design forms, write code, and run your application.

Form Designer

Visual canvas for building your application interface

Toolbox

Collection of controls (buttons, textboxes, labels, etc.)

Code Editor

Where you write your VB6 program logic

Properties Window

Configure settings for forms and controls

Your First VB6 Program

Let's create a simple app that shows a message box when a button is clicked:

MessageBox.vb
Private Sub Command1_Click()
    MsgBox "Welcome to Visual Basic 6!"
End Sub

Output:

This code triggers a pop-up message "Welcome to Visual Basic 6!" when the button named Command1 is clicked.

Displaying Text from a TextBox

Greeting.vb
Private Sub Command2_Click()
    Dim userName As String
    userName = Text1.Text
    MsgBox "Hello, " & userName & "!"
End Sub

Output:

When the user types their name into Text1 (a textbox) and clicks the button labeled Command2, a message box will display a personalized greeting.

Changing the Background Color of a Form

ColorChange.vb
Private Sub Command3_Click()
    ' Change form background color to yellow
    Form1.BackColor = vbYellow
    
    ' Display confirmation message
    MsgBox "Form background color changed!"
End Sub

Output:

This code changes the background color of the form to yellow when the button is clicked, demonstrating how to modify form properties programmatically.
