Visual Basic Programming Language Essay Example for Free

Visual Basic Programming Language Essay A computer program is the set of instructions a computer follows to execute a specific operation that includes to input, process, output and store data to meet unique information needs. Professors John Kemeny and Thomas Kurtz of Dartmouth College as a tool to train students in computer programming created the original basic programming language in the 1960s. (Voon Kiong, 2008) The word basic stands for Beginner’s All-purpose Symbolic Instruction Code. The latest advancement of basic; visual basic programming language has incorporated a graphic interface and event-driven programming. Features of current system It includes several components; first a graphic user interface which provides a fully integrated development environment for easy access to all visual basic development tools. Secondly it incorporates a set of objects such as labels and buttons that can respond to a wide variety of user-initiated events. Thirdly it consists of a vocabulary of statements, methods, and a set of rules for the construction of program codes. Lastly it has the ability to compile stand-alone executable Windows programs. (Mabbutt, 2008) Benefits and uses This programming begins with a form on which the programmer draws all the objects necessary to support the needs of the application and user for example data can be displayed on the in labels that are placed in the form and keyboard input is typically entered via text boxes where command buttons provide access to activities such as printing or exiting the applications. All these are controls which contain both a purpose and a set of predefined events to which they can respond. The programmer writes modules of code called procedures associated with an event of a command button. This approach to programming is a departure from traditional programming that required execution in a top-down manner sequence, which had to be pre-defined. An event-driven program gives the user control over the order in which actions occur. Work cited: Dr. Liew Voon Kiong (2008, 5th November) visual basic tutorial.
