what is visual basic?can u explain clearly and deeply?

Answer 1

Perhaps you might be aware about BASIC language. It was invented by Bill Gates. It is the easiest programming language. But it is not much powerful like C, C++ or other programming language used widely nowadays. This language became very useful to start learning programming for the beginers because of its easy syntax.

To understand what is Visual Basic and why it is required you have to be awared about some basic fundamentals.

Let me explain in detail.

There are two types of applications or softwares:
1) CUI (Character User Interface)
2) GUI (Graphical User Interface)

In CUI there is no Graphics. So we have to use this type of applications by typing commands for using any functionality. For example MS-DOS and Unix.

In GUI everything is shown graphically. You can use almost all functionalities on a single click of mouse. For example Microsoft Windows, Linux, MacOS etc.

If you want to delete a file in Windows then only thing you have to do is click on the file icon and click on the delete icon or press 'delete' key. This is simpler. But if you want to delete a file in DOS then you have enter a command like:

DEL C:\my_folder\my_file.txt

For each operation we have to remember the different commands. So this is somewhat difficult.

In earlier days the programming scope was up to only CUI. But after launching of GUI operating systems like Windows and Macintosh, the scope was expanded up to GUI.

Any GUI application can be partitioned in two major layers:

1) User Interface
2) Back End

User Interface is whatever you see on your screen like buttons, icons, tool bars etc. And the Backe End means whatever occurs in back ground. Foe example: you can see the icons of files, delete button etc on your screen. You can select icon and click on the delete button to delete the file. This is User Interface. But when you do this some execution occurs to delete the file. This is Back End.

When Windows Operating System launched, the programming for Windows based application was more tough because Back End and User Interface both were developed by programming.

After some time, Microsoft launched Visual Basic. In Visual Basic Microsoft saperated out the User Interface development and Back End. User Interface design can be developed with just drag and drop. So it is very fast and easy. For perticular GUI componants like buttons we can add Back End program easily.

In Visual Basic the programming syntax is similar as BASIC language but it's having some more features. So the programming is also very easy.

Thus, Visual basic is bit easy language for WIndows base application programming.

Nowadays, Visual Basic.Net is the lates version and having number of powerful features.

Answer 2

Visual Basic is a Microsoft-hijacked language, it derived from BASIC, a language designed but failed to be foolproofly simple.

The language is simple but just not achieved the hoped level of simplicity, the RAD tool design that Microsoft wrapped around VB 1.0 for DOS furthers that, interfaces are drawn and used immediately. This design was duplicated within Borland Delphi (Pascal).

There are two copy-cats of this design on Linux system, one Visual Basic and one Pascal.

Another hijacked language would be Microsoft JScript.

The original BASIC stuck with its almost non-utility root in the '80s but Visual Basic is refined to incorporate Object-Oriented methodology just like any other language used today. And VB.Net is using Common Language instead of Intel binary as a compiled form; this method is also popularized in Java bytecode as Internet is now popular.

In order to retain smooth transition from older programming methodologies to Object-Oriented, VB has to be bloated for this to happen.

Answer 3

Visual Basic is a programming language. It is used to write programs just depends on your preference.

It gives you a better visual view of what you are doing than some of the other programs.

Answer 4

Visual Basic is a programming language based on BASIC, which is programming language used in the 80's. The reason it is Visual is because you can place your windows, size them, color them, place text, text boxes, option buttons, pull down menus, and just about everything else you see, then add the code to make them work.

Answer 5

Visual Basic is a computer programming language.
It is easy to use it.

Answer 6

A really terrible scripting anguage that only "works" (if you can use that term at all) on Windows.

If you want to learn how to write system automation scripts (and just about anything else), a great place to start is Python.
