Visual Basics (VB) is a event driven programming language which has been developed by Microsoft. VB 1.0 was introduced in 1991. VB was derived from the simplest programming language BASIC, which resembles the high level language and is easily understood by the programmer. VB enables rapid application development (RAD) of GUI applications. It also enables the access to the database using other access methods and it also allows the creation of active controls and objects for various applications.
A programmer can use the pre built components of visual basics and use them in his application to build a GUI environment. VB is very easy to implement and its procedures and functions are easy to write and program written in VB is easily debugged, if any fault occurs. VB is also being used in business programming, mainly 1/3 rd of the developers are using one or the other forms of VB now a days. It is the third most powerful language after C# and Java.
SALIENT FEATURES OF VB :-
Strong integration between windows OS and component object model.
Boolean constant True has numeric value -1.
There is a concept of implicit typecasting.
Data types are promoted to higher types depending upon the result.
VB is now being replaced by its more powerful and new version known as VB.NET( Visual Basics.NET). It is an object oriented language which is developed by Microsoft to work in Microsoft.NET framework. With the backward compatibility of VB, Microsoft had to think for introducing a new highly professional language which should provide every possible compatibility which is required in today’s programming world. Most of developers are using Visual studio.NET for integrated development environment (IDE) applications. It is easy to decompile languages that has aim to Microsoft Intermediate Language, including VB.NET. The data types have been added with double length so to provide as many new GUI applications as possible.
SALIENT FEATURES OF VB.NET SAME AS VB :-
Basic syntax is almost same.
Window forms GUI editor is also same.
Some of the libraries or API are still present in VB.NET which support all the previous programs which have been built on this environment.
SALIENT FEATURES OF VB.NET DIFFERENT FROM VB :-
New data types have been added.
New class libraries have been added for new functionality.
New structured exception handling has been added.
Provide all the complex interfacing standards.
