Introduction
Visual Basic (VB) is an event-driven programming language and integrated development environment (IDE) from Microsoft. Known for its simplicity and ease of use, Visual Basic is widely used for developing Windows-based applications and automating tasks within Microsoft Office. With its straightforward syntax and drag-and-drop GUI designer, Visual Basic is accessible to both beginners and experienced developers.
History of Visual Basic
Visual Basic was first introduced by Microsoft in 1991 as a way to make programming more accessible. It evolved from BASIC (Beginner’s All-purpose Symbolic Instruction Code), a language designed for beginners. Over the years, Visual Basic has undergone several changes, evolving into Visual Basic .NET (VB.NET), which integrates with the .NET framework.
-
Visual Basic 1.0 is released, introducing a new way to create Windows applications with a graphical user interface.
-
Visual Basic 3.0 introduces support for databases and the Microsoft Jet Database Engine.
-
Visual Basic 6.0 is released, adding new features and improvements to the language and IDE.
-
Visual Basic .NET (VB.NET) is introduced, transitioning the language to the .NET framework and adding object-oriented features.
-
Visual Basic 2005 (VB 8.0) enhances productivity with new IDE features and language enhancements.
-
Visual Basic 14 is released, integrated with Visual Studio 2015, offering modern language features and improvements.
-
Microsoft announces that Visual Basic will continue to be supported, but new language features will primarily be developed for C#.
Key Features of Visual Basic
Visual Basic offers several features that make it a popular choice for developing Windows applications:
Ease of Use
Visual Basic’s simple syntax and user-friendly IDE make it accessible to beginners and experienced developers alike.
Rapid Application Development (RAD)
The drag-and-drop interface designer and integrated tools allow for quick and efficient application development.
Integration with Microsoft Office
VB for Applications (VBA) enables automation and customization within Microsoft Office applications.
Event-Driven Programming
Supports the creation of applications that respond to user actions, making it ideal for GUI-based software.
Strong Data Access
Provides robust tools for accessing and manipulating databases through technologies like ADO.NET.
Extensive .NET Framework Integration
VB.NET offers seamless integration with the .NET framework, allowing access to a wide range of libraries and tools.
Visual Basic Ecosystem
Visual Basic is supported by a rich ecosystem of tools, libraries, and frameworks that enhance its capabilities for various application domains:
