Basic, VB, and The History of Visual Basic

On this post I will share what I know about microsoft visual basic 6. Before we get to know Visual Basic, we must know first what is 'BASIC'
BASIC = Beginners' All-purpose Symbolic Instruction Code. BASIC is a group of high level programming language. Literally, The meaning of BASIC is "all-purpose symbolic instruction code that can be used by beginners". Indeed, the term "BASIC Language" here can also be interpreted into a language for beginners, or in other words, referred to as the base language, but it is not 100% true, BASIC can also be used by expert programmers.
BASIC was first developed in 1963 by John George Kemeny and Thomas Eugene Kurtz from Dartmouth College.  At that time, almost all computers need software, and the software was not  sold freely yet, at tah time the only people who can use computers are mathematicians and scientists, because they can build their own software. BASIC language until now  has been heavily modified. Basic Language become the most popular language used on a microcomputer in the late 1970's and home computers in the 1980s.

 Visual Basic are programming language that offers Integrated Development Environment (IDE) to create visual-based software program from Microsoft Windows operating system using a programming model (COM).
Visual Basic is adopted from BASIC programming language and offers high speed computer-based software development graphs.
Some scripting language such as Visual Basic for Applications (VBA) and Visual Basic Scripting Edition (VBScript), Visual Basic is similar as well, but it works differently.
The programmer can build applications by using components provided by Microsoft Visual Basic. Programs that written in Visual Basic can also use the Windows API, but requires additional external function declarations.
In programming for business, Visual Basic has a good market . A survey conducted in 2005 showed that 62% of software developers reported using various forms of Visual Basic, which was followed by a C + +, JavaScript, C #, and Java.






HISTORY OF VISUAL BASIC

Visual Basic 1.0 was introduced in 1991. The concept of programming with drag-and-drop method. Visual Basic application is adapted from the prototype form generator developed by Alan Cooper and his company, named Tripod. Microsoft then contracted with Cooper and his company to develop Tripod into a programmable form system for Windows 3.0, under the code name Ruby.
Tripod does not have a programming language at all. This causes Microsoft decided to combine Ruby with the Basic programming language to create a Visual Basic.

   

  • Visual Basic 1.0 was released for Windows at Comdex / Windows Trade Show in Atlanta, Georgia in May 1991.
  • Visual Basic 1.0 for DOS was released in September 1992. The programming language itself is not very compatible with Visual Basic for Windows, for surely it is the next version of DOS-based BASIC compiler developed by Microsoft itself, which is QuickBASIC. The interface of the program itself uses a text interface, and utilize an additional ASCII codes to simulate the look of the GUI.
  • Visual Basic 2.0 was released in November 1992. Programming environment is easier to use, and speed is improved.
  • Visual Basic 3.0 was released in spring 1993 and comes in two versions: Standard and Professional. VB3 also includes version 1.1 of the Microsoft Jet Database Engine that can read and write database Jet / Access 1.x.
  • Visual Basic 4.0 (August 1995) was the first version that can make the program such as 32-bit 16-bit program. VB4 also introduced the ability to make non-GUI applications. If the previous version using the VBX control, since VB4 was released Visual Basic using the OLE control (with file extension *. OCX), better known later with ActiveX controls.
  • With version 5.0 (February 1997), Microsoft released Visual Basic exclusively for 32-bit versions of Windows. The programmers who prefer to make 16-bit code can either import programs written in VB4 to VB5 version, and VB5 programs can be converted easily into a format VB4.
  • Visual Basic 6.0 (mid 1998) has been improvised in some parts, including new capabilities, which make web applications. Although it is now VB6 is not supported anymore, but the runtime file is still supported until Windows 7.
