Microsoft visual basic
Microsoft visual basic is the fastest and easiest way to create applications for Microsoft windows. Whether one is an experience professional or brand new to windows programming, Visual Basic provides him with a complete set of tools to simplify rapid application development. I straightaway comes to a brief introduction of Microsoft Visual Basic.
So what is visual basic? The “ visual “ part refers to the methods used to create the graphical user inter face (GUI). rather then writing numerous lines of code to describe the appearance and location of inter face element , rebuild objects can simply be dragged and dropped into place of screens.
The “Basic” part refers to the BASIC (Beginners all-purpose symbolic introduction code) language; a language used more programmers then any other language in the history of computing. Visual Basic has evolved from the original basic language and now contains several hundred statements, functions and key words many of which relate directly to the windows GUI. Beginners can create application by learning just a few of the key words, yet the power of the language allows professionals to accomplish using any other windows programming language.
The Visual Basic programming language. is not unique to visual basic .the visual basic programming system , Application addition included in Microsoft excel , SQL server 7.0 and many other windows application using the same language ,the visual basic system scripting edition(Visual Basic script) for internet programming is a subset of the visual basic language . the investment made in learning visual basic will carry over to these other areas.
Visual Basic Edition
Visual basic is available in three versions each geared to meet a specific set of development requirements.
The visual basic learning edition allows programmers to easily create powerful application for Microsoft windows 95, windows 98, windows 2000, windows ME, windows XP and windows NT. it include all intrinsic control’s, plus grid, tab and data-bound controls .Documentation provided with this edition includes learn VB now (A multimedia CD ROM title),a printed programmers guide, online help, plus Visual Basic online.
The professional edition provides computer professionals with a full-featured set of tolls for developing solution for other. It includes all the features of the learning edition, plus edition Active X controls, including inter net controls and the crystal report writer.
Documentation provided with the professional edition includes the programmers Guide, online help, the components tools guide and the crystal report for visual basic users manual.
The enter pries edition allows professional to create robust distributed application in team setting it includes all the features of the professional edition, plus the automation manager, component manager database
Control structure allows the programmer to control the flow of his programs execution. If left unchecked by control- flow statements, programs logic will flow through from left to right and top to bottom. While some very simple programs can be written with only this unit directional flow, and while some flow can be decontrolled by using operators to regular precedence of operations, most of the power and utility of any programming language comes form its ability to change statements under with structure and loops.
When an application is created in Visual Basic, objects are worked with objects are provided by Visual Basic -such as control, forms and data access objects other application objects can also be controlled from with in and other Visual Basic application own object can also be created, and additional properties and methods can be define for them.
THE USERS INTERFACE
The user interface is per haves the most important part of an application; it’s certainly the most visible. To user, the interface is the application, they probably are not aware of the code that is executing behind the scenes. No matter how much time effort is put in writing and optimizing the code, the usability of an application depends on the interface.
Transaction System: A transaction is a record of some well-defined single and usually small occurrence in a system. Transactions are input into the computer to update the database files. It checks the entering data for its accuracy. This means that numeric data appears in numeric field and character data in character field. Once all the checks are made, transaction is used to update the database. Transaction can be inputted in on-line mode or batch mode. In on-line mode, transactions are entered and updated into the database almost instantaneously. In batch mode, transactions are collected into batches, which may be held for a while and inputted later.
Decision Support System: It assists the user to make analytical decision. It shows the various data in organized way called analysis. This analysis can be made to syrdy preferences and help in making decisions.
Computer system works out best with record maintenance. It will tell you which customer would get how much pending/reports statements. It will also help to search the information about a particular person by simply entering his telephone number.
