what the usage of visual basic?

Question

can anyone explain?i hope have a long paragraph

Answer 1

VB is a program language that enables people to write programs that can be used by other people. Unlike old GW Basic or Basic, modern VB is a very powerful environment that is used in a number of applications. It can be used to develop simple form based applications, to games, etc.



It is no longer considered a programming language for amateurs . It is used by a number of businesses for development of internal programs for use in their day to day operation.



From Wiki:

Visual Basic (VB) is the third-generation event-driven programming language and integrated development environment (IDE) from Microsoft for its COM programming model. VB is also considered a relatively easy to learn and use programming language, because of its graphical development features and BASIC heritage.[1]



Visual Basic was derived from BASIC and enables the rapid application development (RAD) of graphical user interface (GUI) applications, access to databases using Data Access Objects, Remote Data Objects, or ActiveX Data Objects, and creation of ActiveX controls and objects. Scripting languages such as VBA and VBScript are syntactically similar to Visual Basic, but perform differently.[2]



A programmer can put together an application using the components provided with Visual Basic itself. Programs written in Visual Basic can also use the Windows API, but doing so requires external function declarations.



The final release was version 6 in 1998. Microsoft's extended support ended in March 2008 and the designated successor was Visual Basic .NET (now known simply as Visual Basic).

Answer 2

It is a programming language.

Tasks that need to be done by a computer need the instructions in the form of machine code. In order for that machine code to be easily written and edited it is usually converted into a language more easily understood by a human. Hence the programming language.

A computer actually works by a series of instructions made up from 0 and 1 (binary) or off and on. Depending on the width of the machines components (like 8bit, 16bit etc) your instruction set can be (8bit): 00000000 to 11111111 This gives you 256 combinations. So let's say the instruction to the computer for a RETURN needs to be 01101100.

These binary codes are usually converted to something called Hexadecimal which consist of numbers and letters. I think RETURN is C9 (that should represent 01101100 but as I guessed it, it probably doesn't!). Ok, so it is a lot easier to remember C9 rather than the 8bit binary number, but we can go one step further by using a programming language like BASIC (or visual basic). These languages are compiled or assembled from and to machine code: I am not sure which way round it is! Anyway if you write RETURN in Visual Basic it tells the computer to do the same thing as C9 or 01101100!! A lot easier I am sure you will agree.

It is no good as a games program as it is too slow. By the time the instructions were converted you would be shot dead.

Visual Basic is a programming language developed by Microsoft to create applications. Visual basic comes in many varieties including VB.net, vb6 and VBscript a simplified version used only for scripts (No form involved). It can also be used in the web using the tag
