Visual Basic is a programming language and development environment created by Microsoft in 1991 that allowed developers to build Windows applications by visually designing user interfaces and writing code in an English-like syntax. It was one of the first languages to make graphical application development accessible to non-expert programmers, and it became one of the most widely used programming languages in history.

At its peak in the late 1990s, there were an estimated 6 million Visual Basic developers worldwide — more than any other programming language at the time.

Why Visual Basic Mattered

To understand Visual Basic’s significance, you need to understand what programming looked like before it arrived.

In 1990, if you wanted to build a Windows application, you wrote C code. A lot of C code. Just creating a basic window with a button required hundreds of lines of complex, error-prone code dealing with Windows message loops, window classes, device contexts, and callback functions. The learning curve was brutal, and the barrier to entry was enormous.

Visual Basic changed everything. Suddenly, you could drag a button onto a form, double-click it, and type what should happen when someone clicks it. The form designer handled all the underlying Windows API complexity. You didn’t need to understand message pumps or window handles or any of the low-level plumbing. You just designed what it looked like and wrote what it should do.

The effect was seismic. Accountants wrote inventory management tools. Scientists built data collection interfaces. Small business owners created custom databases. Teachers made educational software. People who would never have called themselves programmers were building functional Windows applications.

This wasn’t universally celebrated. Professional C and C++ developers dismissed Visual Basic as a “toy language” — and honestly, they had some technical justification. VB programs were slower, larger, and less flexible than equivalent C code. But they missed the point entirely. Visual Basic wasn’t competing with C. It was making programming possible for millions of people who would never have learned C.

The Evolution of Visual Basic

Visual Basic 1.0 (1991)

The original release was almost startlingly simple. It combined Microsoft’s existing BASIC language with a visual form designer inspired by the Ruby programming environment (developed by Alan Cooper, who’s often called “the father of Visual Basic”). The language had maybe a few dozen keywords, limited data types, and no real object-oriented features.

But it worked. You could build a functioning Windows application in an afternoon. The “Hello World” program that took 150 lines of C code took about 3 in Visual Basic. The development community responded with enthusiasm.

Visual Basic 3.0 (1993)

VB3 was the first version that was genuinely capable. It included built-in database support through the Jet database engine (the same engine behind Microsoft Access), making it trivially easy to build database-driven applications. This was a killer feature — suddenly small businesses could build custom database applications without hiring expensive consultants.

The DAO (Data Access Objects) model let you connect to databases, run queries, and display results in data-bound controls with almost no code. For business applications, this was more than enough.

Visual Basic 4.0-5.0 (1995-1997)

These versions added increasingly serious capabilities. VB4 introduced 32-bit compilation for Windows 95, classes (limited object-oriented programming), and the ability to create OLE Automation servers. VB5 added native code compilation (programs ran significantly faster) and the ability to create ActiveX controls — reusable components that could be embedded in web pages through Internet Explorer.

The ActiveX era was VB’s browser moment. For a brief period in the mid-to-late 1990s, Visual Basic components ran inside web pages. It was slow, insecure, and only worked in Internet Explorer, but it existed — and it gave VB developers a (limited) on-ramp to web development.

Visual Basic 6.0 (1998)

VB6 was the peak. It was fast enough, capable enough, and stable enough to build serious business applications. ADO (ActiveX Data Objects) replaced DAO for database access. The IDE was polished and productive. A massive ecosystem of third-party controls and components existed.

VB6 applications ran everything from small business accounting systems to banking front-ends to medical records systems. Many of these applications are still running today — over 25 years later — because they work, nobody wants to pay for a rewrite, and the cost of replacing a system that “just works” is hard to justify.

Microsoft released VB6 in September 1998. They had no idea it would be the last “classic” version.

VB.NET (2002 — present)

When Microsoft announced the .NET Framework, they also announced Visual Basic .NET — a completely redesigned language that shared the Visual Basic name but was, in many important ways, a different language entirely.

VB.NET was fully object-oriented, type-safe, and ran on the Common Language Runtime (CLR) alongside C#. It had inheritance, interfaces, structured exception handling, multithreading support, and access to the entire .NET class library. It was a far more powerful language than VB6.

It also broke backward compatibility. VB6 code couldn’t simply be ported to VB.NET — it required significant rewriting. Microsoft provided migration tools, but they only handled simple cases. Complex VB6 applications required substantial manual effort to convert.

The VB6 developer community was furious. Many felt betrayed — they’d invested years in a platform that Microsoft was essentially abandoning. A “VB6 forever” petition gathered tens of thousands of signatures. Some developers migrated to VB.NET. Others switched to C# (figuring that if they had to learn a new language anyway, they might as well learn the one Microsoft clearly preferred). Others stayed on VB6 as long as possible.

VBA: Visual Basic’s Most Enduring Legacy

Visual Basic for Applications (VBA) is arguably more widely used today than any version of standalone Visual Basic ever was. It’s the macro language embedded in Microsoft Office — Excel, Word, Access, PowerPoint, and Outlook.

If you’ve ever recorded a macro in Excel or automated a Word document, you’ve used VBA. It’s based on the VB6 language (not VB.NET) and provides programmatic access to the host application’s object model.

Excel VBA is by far the most common use case. Financial analysts, accountants, scientists, and business analysts write VBA macros to automate repetitive spreadsheet tasks, create custom functions, build data processing pipelines, and generate reports. Some Excel VBA applications are staggeringly complex — multi-thousand-line programs that process data, interact with databases, generate charts, and send emails.

The running joke in finance is that the world’s financial infrastructure runs on Excel spreadsheets with VBA macros. It’s not entirely a joke. Trading firms, insurance companies, and banks still rely heavily on VBA-powered spreadsheets for risk analysis, pricing models, and reporting.

VBA’s durability is remarkable. Microsoft has essentially frozen its development — no significant new features since Office 2010 — but it remains the most accessible way to automate Office tasks. Python integration in Excel is gradually emerging as an alternative, but VBA’s installed base is so enormous that it will persist for decades.

The Language Itself

Visual Basic’s syntax was designed to be readable and beginner-friendly. Where C uses cryptic symbols, VB uses English words.

C: if (x > 5) { y = x * 2; } else { y = 0; }

VB: If x > 5 Then y = x * 2 Else y = 0 End If

This readability was a deliberate design choice. The language was descended from BASIC (Beginner’s All-purpose Symbolic Instruction Code), which was specifically designed in the 1960s to be easy for non-scientists to learn. Visual Basic inherited that philosophy.

Key language features across versions:

Event-driven programming. VB applications are organized around events — button clicks, form loads, timer ticks, key presses. You write code that responds to events rather than code that runs sequentially from start to finish. This model maps naturally to graphical user interfaces.

Variant data type. Classic VB had a “Variant” type that could hold any kind of data — strings, numbers, dates, objects, arrays. This was convenient (no need to declare types) but slow and error-prone. VB.NET largely eliminated this in favor of strong typing.

String handling. VB had excellent built-in string manipulation functions — Mid, Left, Right, InStr, Replace, Split, Join. For text processing applications, VB code was often more concise and readable than equivalent C code.

Error handling. Classic VB used the infamous On Error GoTo and On Error Resume Next statements — a form of error handling that purists despised but that was simple enough for beginners. VB.NET replaced this with structured Try/Catch blocks, matching modern programming practice.

COM integration. Classic VB was deeply integrated with Microsoft’s Component Object Model (COM). You could instantiate any COM object — including Office applications, Windows services, and third-party components — with a single line of code. This made VB the glue language for automating Windows.

The Culture Wars

Visual Basic triggered one of programming’s longest-running cultural debates: is accessibility a feature or a flaw?

The “real programmers don’t use VB” camp argued that VB encouraged bad habits — poor error handling, spaghetti code, ignorance of memory management, and an overall lack of rigor. They pointed (often correctly) to VB applications that were unmaintainable messes of global variables and GoTo statements.

The “VB democratized programming” camp countered that most software doesn’t need to be elegant — it needs to solve a problem. A working inventory system written by a small business owner in VB is infinitely more valuable than the “proper” C++ application they never would have built.

Both sides had valid points. Many VB applications were genuinely awful code. And many of those awful applications were genuinely useful software that solved real problems for real people. The tension between code quality and accessibility hasn’t been resolved — it’s just moved to new languages. Today, the same arguments play out around Python, JavaScript, and no-code platforms.

Visual Basic’s Influence on Modern Programming

Several concepts that Visual Basic pioneered or popularized are now standard across the industry.

Visual form designers. The idea that you design a UI by dragging and dropping components onto a canvas — rather than writing layout code — became universal. Every modern IDE has a visual designer. Xcode, Android Studio, Visual Studio (for C# and other .NET languages), and numerous web frameworks all use this approach.

RAD (Rapid Application Development). VB proved that you could go from idea to working application in hours or days rather than weeks or months. The RAD philosophy influenced tools like Delphi, PowerBuilder, and later, modern web frameworks with hot reload and rapid prototyping capabilities.

Integrated debugging. VB’s ability to pause execution, inspect variables, change code, and resume — all within the same IDE — was revolutionary. Today, every serious IDE offers this, but VB was among the first to make it seamless.

IntelliSense (autocomplete). VB popularized the dropdown list of available properties and methods that appears as you type. This feature is now so standard that programming without it feels primitive. The algorithms behind modern autocomplete have evolved far beyond VB’s original implementation, but the concept traces directly back.

Component-based development. VB’s ecosystem of third-party controls — grids, charts, menus, calendars — established the model of building applications by assembling pre-built components. This philosophy lives on in npm packages, NuGet libraries, Python packages, and every modern component ecosystem.

The Current State

As of 2025, Visual Basic exists in several forms with very different levels of vitality.

VB.NET is supported but not growing. Microsoft announced in 2020 that VB.NET would receive stability and compatibility updates but no new language features. The .NET runtime continues to evolve, and VB.NET code continues to work on new .NET versions, but all new language development energy goes to C#. The message is clear: VB.NET isn’t going away, but it’s not the future.

VBA remains entrenched in Microsoft Office. Despite Microsoft’s introduction of Office Scripts (TypeScript-based) and Power Automate as modern alternatives, VBA macros are still the most common way to automate Excel, Word, and Access. The installed base of VBA code is so vast that it will take decades to replace — if it ever is.

VB6 applications still run in production at many organizations. The VB6 runtime ships with Windows 11 and will likely continue to be included for the foreseeable future. Microsoft has repeatedly extended its support commitment because so many businesses depend on VB6 applications. Some companies have been running the same VB6 applications for 20+ years.

Legacy migration is a significant industry. Consultancies specialize in migrating VB6 and VBA applications to modern platforms — .NET, web applications, or cloud services. The migration work is technically straightforward but organizationally complex because the original developers are often long gone, documentation is sparse, and business logic is buried in code that nobody fully understands.

Lessons from Visual Basic

Visual Basic’s story contains several lessons that remain relevant.

Accessibility drives adoption. The easiest tool to use will attract the most users, even if it’s technically inferior. VB was slower and less capable than C++, but it had 10x the user base because normal people could actually use it.

Developer ecosystems matter. VB’s third-party control market, its books (there were entire bookstore shelves dedicated to VB), its magazines, its user groups — these created a self-reinforcing community that kept people in the VB ecosystem. Modern platforms understand this lesson well.

Breaking backward compatibility is expensive. The VB6-to-VB.NET transition remains one of the most contentious platform migrations in programming history. Developers invested years of effort into VB6, and telling them to rewrite everything was met with justifiable anger. Apple and Google have learned from this — both handle platform transitions more carefully now, though sometimes they still get it wrong.

“Good enough” software has value. The programming world tends to judge software by code quality. Users judge software by whether it solves their problem. Visual Basic produced enormous amounts of “good enough” software that solved real business problems, and that matters — even if the code wouldn’t pass a modern code review.

Visual Basic may be fading from active development, but its influence on how we think about programming accessibility, visual design tools, and rapid application development is permanent. Every time you drag a button onto a form in any modern development environment, you’re using an idea that Visual Basic helped make standard.

Frequently Asked Questions

Is Visual Basic still used in 2025?

VB.NET is still supported by Microsoft and used in some enterprise applications, though new development has largely shifted to C#. VBA (Visual Basic for Applications) remains widely used in Microsoft Office, especially Excel. Classic VB6, however, is effectively dead for new projects.

What is the difference between VB6, VB.NET, and VBA?

VB6 (Visual Basic 6.0) was the last version of classic Visual Basic, released in 1998. VB.NET is a completely redesigned language running on Microsoft's .NET framework. VBA (Visual Basic for Applications) is a stripped-down version embedded in Microsoft Office applications for automation and macros.

Is Visual Basic good for beginners?

Yes — it was literally designed for beginners. Its English-like syntax, visual form designer, and immediate feedback loop make it one of the most accessible programming languages ever created. Many professional developers started with Visual Basic before moving to other languages.

Can you build modern applications with Visual Basic?

VB.NET can technically build modern desktop, web, and cloud applications using the .NET framework. However, Microsoft announced in 2020 that it would no longer add new language features to VB.NET, making C# the preferred .NET language for new projects.

Why did Microsoft stop developing Visual Basic?

Microsoft hasn't fully stopped — VB.NET still receives bug fixes and compatibility updates. But the company shifted investment to C# because maintaining feature parity between two languages with different design philosophies was unsustainable, and the developer community had largely moved to C#.
