Getting Started with Microsoft Small Basic: A Beginner’s Guide

Transitioning from Small Basic to Visual Basic: A RoadmapTransitioning from Microsoft Small Basic to Visual Basic (VB) is a natural progression for learners who want to move from an approachable, block-free beginner language to a more powerful, professional environment. This roadmap lays out a clear, practical path — skills to learn, projects to build, pitfalls to avoid, and resources to use — so you can make the switch with confidence.

Why move from Small Basic to Visual Basic?

Small Basic is intentionally minimal: it exposes beginners to programming fundamentals without overwhelming syntax or large APIs. Visual Basic, especially in the form of Visual Basic .NET (VB.NET) using Visual Studio, offers:

• Richer language features (strong typing, object-oriented programming, generics)
• Comprehensive standard libraries for GUI, data access, networking, and more
• Professional tooling (IntelliSense, designers, debugging, testing)
• Better career and project opportunities for desktop, web, and enterprise apps

Key conceptual differences

• Syntax strictness and typing:
  • Small Basic uses a forgiving, dynamic-like approach with very simple syntax.
  • Visual Basic enforces more structure: declarations, types (Integer, String, Boolean, etc.), and optional strict mode (Option Strict).
• Object-oriented programming:
  • Small Basic is largely procedural.
  • VB supports classes, inheritance (via interfaces and base classes), properties, events, and advanced design patterns.
• Development environment:
  • Small Basic provides a simplified IDE and Turtle graphics.
  • Visual Studio/Visual Studio Code provides project management, designers, NuGet package management, and advanced debugging.
• Error handling:
  • Small Basic has minimal error handling.
  • VB uses structured exception handling with Try…Catch…Finally.
• Deployment:
  • Small Basic programs are simple and often run in a sandboxed environment.
  • VB apps can be compiled into assemblies, deployed as EXE, or published for web and cloud.

Roadmap: step-by-step path

1. Strengthen fundamentals (1–2 weeks)
   • Review variables, control flow (If, Select Case), loops (For, While, For Each), and basic data structures (arrays, dictionaries).
   • Practice converting Small Basic programs to VB syntax. Example: translate a Small Basic loop or Turtle drawing into equivalent VB code.
2. Learn Visual Basic syntax and project structure (2–4 weeks)
   • Set up Visual Studio (Community edition) or Visual Studio Code with the VB.NET extension.
   • Understand Solution, Project, Module, Namespace, and Class structures.
   • Learn variable declarations, Option Strict/Explicit, and basic input/output (Console.ReadLine/WriteLine).
3. Master object-oriented basics (3–6 weeks)
   • Create classes, constructors, properties, methods, and understand access modifiers (Public, Private, Protected, Friend).
   • Practice small OOP exercises: modeling a bank account, a simple inventory system, or a game entity.
4. Build GUI apps with Windows Forms or WPF (4–8 weeks)
   • Start with Windows Forms for rapid results: use the designer, drag-and-drop controls, wire events (Click, Load).
   • Progress to WPF for modern UI using XAML; learn data binding and MVVM basics.
   • Convert a Small Basic GUI-style project (like a drawing app or calculator) into a WinForms/WPF app.
5. Learn error handling and debugging (1–2 weeks)
   • Use Try…Catch…Finally, throw exceptions, and create custom exceptions where appropriate.
   • Learn breakpoints, watch windows, step-in/step-over, and immediate window in Visual Studio.
6. Work with I/O, files, and data (2–4 weeks)
   • Read/write text and binary files, use FileStream, StreamReader/StreamWriter, and Path utilities.
   • Learn serialization (JSON/XML) for saving structured data.
7. Databases and persistence (3–6 weeks)
   • Use ADO.NET for direct database access or Entity Framework for an ORM approach.
   • Practice CRUD operations with SQLite or SQL Server Express.
8. Advanced topics and ecosystem (ongoing)
   • Explore async/await for asynchronous programming, LINQ for data queries, generics, delegates, and events.
   • Learn to use NuGet packages and integrate libraries.
   • Understand deployment options: ClickOnce, MSIX, self-contained executables, or publishing to Azure.

Practical project progression

• Beginner: Console-based quiz, number guessing game, or text-based adventure (reinforce loops, conditionals, I/O).
• Intermediate: Calculator, TODO list app with file storage, or a simple drawing program using Windows Forms (learn events, controls, file I/O).
• Advanced: Personal finance manager with database storage, or a small inventory system using Entity Framework and a WPF front-end (learn data binding, database work, MVVM).
• Capstone: Convert a multi-feature Small Basic project into a polished VB application with installer and basic tests.

Common pitfalls and how to avoid them

• Skipping Option Strict: Always enable Option Strict On to avoid implicit conversions and catch type errors early.
• Ignoring namespaces and project organization: Use namespaces, separate classes into files, and keep SOLID principles in mind.
• Overusing WinForms for complex UIs: For modern, scalable UIs prefer WPF with MVVM.
• Underusing debugging tools: Learn Visual Studio debugging early; it saves time and reveals runtime issues that static reading won’t catch.

Learning resources

• Visual Studio Community edition (free) — IDE for building VB apps.
• Microsoft Learn — official tutorials and modules for VB.NET, WinForms, WPF, and ASP.NET.
• Books: “Programming Visual Basic .NET” (latest editions), “Pro WPF in .NET” for UI.
• Hands-on: GitHub sample projects, NuGet packages, and community forums.

Sample translation snippets

Small Basic:

For i = 1 To 10   TextWindow.WriteLine(i * i) EndFor 

Visual Basic:

For i As Integer = 1 To 10     Console.WriteLine(i * i) Next 

Small Basic (sub):

Sub SayHello   TextWindow.WriteLine("Hello") EndSub 

Visual Basic (method):

Sub SayHello()     Console.WriteLine("Hello") End Sub 

Timeline example (6 months plan)

• Months 1–2: Fundamentals, VB syntax, console apps.
• Months 3–4: OOP, GUI with WinForms, basic debugging.
• Months 5–6: Databases, WPF/MVVM, async programming, capstone project.

Final advice

Treat the transition as learning to drive a more powerful car: same basic controls but many more features and responsibilities. Take small, frequent projects, keep code organized, and use Visual Studio tools to iterate quickly.
