Visual Basic was developed by Microsoft for Windows, and is known for supporting rapid application development (RAD) of graphical user interface (GUI) applications, event-driven programming, and both consumption and development of components via the Component Object Model (COM) technology.
In 1991, Microsoft introduced the Visual Basic Extension (VBX) technology with Visual Basic 1.0. A VBX is a packaged extension in the form of a dynamic-link library (DLL) that allows objects to be graphically placed in a form and manipulated by properties and methods. These were later adapted for use by other languages such as Visual C++.
The class defines the data format or type (including member variables and their types) and available procedures (class methods or member functions) for a given type or class of object. Objects are created by calling a special type of method in the class known as a constructor .
This is called a class, or object (an object is created based on a class). Each object serves a separate function. It is defined by its properties, what it is and what it can do. An object can be part of a class, which is a set of similar objects. Information hiding: The ability to protect some object components from external entities.
Visual Basic (VB), originally called Visual Basic .NET (VB.NET), is a multi-paradigm, object-oriented programming language, implemented on .NET, Mono, and the .NET Framework. Microsoft launched VB.NET in 2002 as the successor to its original Visual Basic language, the last version of which was Visual Basic 6.0.
In Microsoft Windows applications programming, OLE Automation (later renamed to simply Automation [1] [2]) is an inter-process communication mechanism created by Microsoft.It is based on a subset of Component Object Model (COM) that was intended for use by scripting languages – originally Visual Basic – but now is used by several languages on Windows.
It would be better to think of Visual Basic .NET as a new language inspired by the classic Visual Basic rather than as a continuation of Visual Basic 6.0, with the added difficulty for migrating programmers that VB.NET interfaces with the .NET Framework whereas VB6 was based on the Component Object Model (COM).

Visual Basic is a name for a family of programming languages from Microsoft. It may refer to: Visual Basic (.NET), the current version of Visual Basic launched in 2002 which runs on .NET; Visual Basic (classic), the original Visual Basic supported from 1991 to 2008; Embedded Visual Basic, the classic version geared toward embedded applications
