Visual Basic 6 Is Not Dead

Microsoft retired the VB6 IDE in 2008, but the language never went away. Millions of lines of VB6 code still run in production. Thousands of developers still prefer its clarity. WebVB Studio brings it back — in a modern browser, with modern controls.

1991

Visual Basic launched — revolutionized desktop app development with drag-and-drop GUI design.

1998

VB6 released — the most popular version ever. Still running in enterprises, banks, and manufacturing worldwide.

2026

WebVB Studio — VB6 reborn in the browser. Same syntax, same events, new superpowers: MQTT, Charts, Pandas, AI.

Why Visual Basic?

The Language That Gets Out of Your Way

Readable Syntax

If x > 10 Then lblResult.Caption = "High" — you can read VB6 code like English. No curly braces, no semicolons, no cryptic symbols.

Visual Form Designer

Drag a Button, double-click it, write Sub cmdSave_Click. That's it. No HTML, no CSS, no layout managers. Design your GUI visually.

Event-Driven Model

Every control raises events. Write Sub Timer1_Timer, Sub lstItems_Click, Sub txtSearch_Change. No callbacks, no binding, no wiring.

Beginner-Friendly

VB6 was how millions of developers learned to program. The learning curve is gentle. See a button, click it, write the handler. Instant results.

Also Supports Python

Switch to Python any time. Same form, same controls, same events — different language. Use Pandas, NumPy, and data science libraries when you need them.

Rapid Development

VB6 was born for RAD. Design the form in minutes, write event handlers, hit Run. Build a working app in 15 minutes, not 15 hours.

VB6 Code That Just Works

Familiar VB6 syntax. Event-driven handlers. All 32+ examples run directly in WebVB Studio.

Beginner Calculator

Calculator App

Dim Result As Double
Sub cmdEquals_Click
Result = Val(txtDisplay.Text)
txtDisplay.Text = Str(Result)
End Sub

Full working calculator — design the buttons visually, handle events in VB6.

Open example
Intermediate Database

Product Database (CRUD)

Sub Form1_Load
Data1.CreateTable "Products", "Name;Price;Stock"
End Sub
Sub cmdAdd_Click
Data1.AddNew
Data1.Fields("Name") = txtName.Text
Data1.Fields("Price") = txtPrice.Text
Data1.Update
End Sub

Full CRUD operations with the built-in Database control. No SQL needed.

Open example
Advanced MQTT / IoT

MQTT IoT Dashboard

Sub Mqtt1_Connect
Mqtt1.Subscribe "sensor/+/temp"
End Sub
Sub Mqtt1_Message(topic, payload)
GaugeTemp.Value = Val(payload)
Chart1.AddPoint "Now", Val(payload), "red"
End Sub

Real-time IoT monitoring — connect to MQTT brokers, display on gauges and charts.

Open example
Advanced E-commerce

Full Webshop App

Sub cmdAddToCart_Click
Dim item As String
item = grdProducts.TextMatrix(grdProducts.Row, 1)
lstCart.AddItem item
UpdateTotal
End Sub

Complete e-commerce app with product catalog, shopping cart, and order processing.
