Tutorial Visual Basic
Visual Basic (VB) is an ideal programming language for developing sophisticated professional applications for Microsoft Windows. It makes use of Graphical User Interface for creating robust and powerful applications. The Graphical User Interface as the name suggests, uses illustrations for text, which enable users to interact with an application. This feature makes it easier to comprehend things in a quicker and easier way.
Coding in GUI environment is quite a transition to traditional, linear programming methods where the user is guided through a linear path of execution and is limited to small set of operations. In GUI environment, the number of options open to the user is much greater, allowing more freedom to the user and developer. Features such as easier comprehension, user-friendliness, faster application development and many other aspects such as introduction to ActiveX technology and Internet features make Visual Basic an interesting tool to work with.
Visual Basic (VB) was developed from the BASIC programming language. In the 1970s, Microsoft started developing ROM-based interpreted BASIC for the early microprocessor-based computers. In 1982, Microsoft QuickBasic revolutionized Basic and was legitimized as a serious development language for MS-DOS environment. Later on, Microsoft Corporation created the enhanced version of BASIC called Visual Basic for Windows.
Visual Basic (VB) is an event-driven programming language. This is called because programming is done in a graphical environment unlike the previous version BASIC where programming is done in a text only environment and executed sequentially in order to control the user interface. Visual Basic enables the user to design the user interface quickly by drawing and arranging the user elements. Due to this spent time is saved for the repetitive task.
Important Features of Visual Basic (VB)
- Full set of objects - you 'draw' the application
- Lots of icons and pictures for your use
- Response to mouse and keyboard actions
- Clipboard and printer access
- Full array of mathematical, string handling, and graphics functions
- Can handle fixed and dynamic variable and control arrays
- Sequential and random access file support
- Useful debugger and error-handling facilities
- Powerful database access tools
- ActiveX support
- Package & Deployment Wizard makes distributing your applications simple
Visual Basic 6 vs Previous versions of Visual Basic
The original Visual Basic for DOS and Visual Basic For Windows were introduced in 1991.
Visual Basic 3.0 (a vast improvement over previous versions) was released in 1993.
Visual Basic 4.0 released in late 1995 (added 32 bit application support).
Visual Basic 5.0 released in late 1996. New environment, supported creation of ActiveX controls, deleted 16 bit application support.
Visual Basic 6.0 - released in mid 1998s - some identified new features of Visual Basic 6.0:
- Faster compiler
- New ActiveX data control object
- Allows database integration with wide variety of applications
- New data report designer
- New Package & Deployment Wizard
- Additional internet capabilities.
If you ever used Visual Basic 3, you too could have known everything. Visual Basic 3 was a reasonably small but powerful language. Visual Basic 4 added classes to the language and made Visual Basic much more complicated. Versions 4, 5, and 6 added more support for database programming and other topics such as custom controls, but Visual Basic was still a fairly understandable language, and if you took the time you could become an expert in just about all of it.
Visual Basic.NET accelerated the expansion of Visual Basic tremendously. The .NET Framework added powerful new tools to Visual Basic, but those tools came at the cost of increased complexity. Associated technologies have been added to the language at an ever - increasing rate, so, today, it is impossible for anyone to be an expert on every topic that deals with Visual Basic.
System requirements for Visual Basic depends on the version of Visual basic software. Visual Basic 6 for windows requires at least Microsoft Windows 95/Windows NT 3.51, 486 processor and a minimum of 16 MB of RAM. A complete installation of the most powerful version of Visual Basic 6.0, the Enterprise Edition, requires more than 250 MB of Hard Disk space.
