Visual Basic is an event driven programming language. In other words it can be simply described as a technology used for developing user friendly and user understandable graphical user interfaces. It is a product of Microsoft and namely has various versions such as the working model, professional edition, the enterprise edition etc. Depending upon the needs of the developer the editions used may change.

Visual Basic projects can be developed in a three step process:

• Planning and designing the user interface
• Setting the properties of the various controls
• Coding for the various events of the controls

The whole concept of Visual Basic is based on forms, controls, events, properties etc. The forms are the screen or the window. The controls are placed on the form by the developer keeping in mind the needs of the user. The controls have built in properties and events. The property of the control is changed as per the user requirements. The coding for the validations of the controls is done at the various events of the controls. The textbox control is used to provide a text area for the user to enter some data such as address, name etc. The labels are used to let the user know what the control next to it is for. When a user has to select one of the option from various options given we can use the option buttons, if multiple selection has to be made then checkboxes can be used. To give a more graphical effect, the controls such as picture and image can be used. There is a long list of controls, depending upon the requirements the various controls can be utilized.
Visual Basic 6.0 was one of the main programming technologies used to create client server applications that were widely used in a large number of organizations. The applications would usually be called 3-tier applications where the user interface (client) and server part were coded in Visual Basic to interact with the database to fetch and save data. Visual Basic compatible with databases like SQL Server, Microsoft access etc. With the help of Visual Basic even reports can be generated which helps user to get a day–to–day summary.
With the growing advancements and needs Visual Basic 6.0 has also achieved advancements. The latest technology is Visual Basic .NET which is a part of the .NET package. Currently all the applications that are based on Visual Basic 6.0 are being ported to Visual Basic .NET to be able to use the latest features and advantages that the .NET platform brings along with it.
