Definition
Visual Basic is a computer language (more precisely, a family of
languages) created and developed by Microsoft Corporation, as
well as an integrated development environment. It is a further
development of the QuickBASIC language (also developed by
Microsoft), from which it inherited the general concept, style and
syntax.
Application
However, the development of
Visual Basic has moved towards
procedural, object, component
and event programming. The
language is actively used both for
developing Windows applications
and for creating software for other
platforms. Visual Basic can be
downloaded and used both
separately and as part of
Microsoft Visual Studio.
History of development
The history of Visual Basic began in 1991,
when Microsoft released the first version of
the new language for its Windows operating
system based on the QuickBASIC syntax. An
innovation that highlights the novelty was the
connection with the graphical interface,
previously implemented by programmer Alan
Cooper in the Tripod prototype. But it was in
Visual Basic 1.0 that this implementation
reached the desired level.
Feature
The main feature of Visual Basic that distinguishes it from most
languages is the use of a graphical interface in programming.
Moreover, VB has several more features:
1.
Logical and bitwise operators are combined.
2.
The so−called Boolean constant "true" has a numeric value of -1, and "false" is 0.
3.
Integers are automatically converted to real numbers after division is applied
4.
Arrays are declared with upper and lower bounds defined, just like in Pascal and
Fortran.
Advantages and Disadvantages


Simplicity

High speed of development.
Strict binding to the
programming environment.

Powerful support.


Error protection.

Strong typing.
Limited cross-platform.

Slow operation of programs.
Visual Basic Versions
Visual Basic Classic

it can only be used as a tool for creating applications for Windows
Visual Basic for Applications (VBA)

it was developed for the purpose of writing macros and other application
programs for specific applications.
Visual Basic Scripting Edition (VBScript)

it is used to automate the administration of Windows-based systems
Visual Basic .NET

When using Visual Basic .NET can no longer work with the old methods, so it can
be safely called a separate language.

Conclusion
In 2020, Microsoft announced that it was stopping the
development of this language (more precisely, its Visual
version Basic.Net ), although it will continue to be released in
the Visual Studio bundle.
Visual Basic has become one of Microsoft's landmark
achievements and has influenced the development of other
computer languages. Some of the solutions implemented in it
were used in the same C#. It also became an excellent "study
desk" for many specialists, who then switched to more indemand YAP.
