1. Introduction
language - formal sign system designed for recording computer programs. The programming language defines a set of lexical, syntactical and semantical rules, that specify the appearance of programs and activities that comply with the Executive (the computer) under its management. One example is the programming language Visual Basic from Microsoft.Visual Basic - is a software development tool, developed by Microsoft, and includes a programming language and development environment. Visual Basic language has inherited the spirit, style and syntax part of his ancestor - the language BASIC, which has many dialects. At the same time, Visual Basic combines procedures and elements of object-oriented and component-oriented programming languages. VB development environment includes tools for visual designing the user interface.Basic considered being a good tool for rapid program prototyping, for database application development and, in general, for component ways to create programs that are running operating systems of Microsoft Windows family.first recognition by major developers Visual Basic received after the release of the third version - VB3. Final acceptance as a full-fledged programming tool for Windows - with the release of the fifth version - VB5. VB6 version, part of the Microsoft Visual Studio 6.0, has become a truly mature and feature-rich product. After that, the developers of Microsoft have significantly changed the development direction of this technology. As at September 2010 we can speak not only about classic Visual Basic, but also its dialects Visual Basic for Applications (VBA) and Visual Basic Scripting Edition (VBScript). br/>
. Visual Basic Scripting Edition
Basic Scripting Edition (usually just VBScript) - scripting programming language, is interpreted by Windows Script Host. Is a few truncated version of the usual Visual Basic, appeared in 1991. In the middle of 1998 "seceded" from Visual Basic 6.0. VBScript is used mainly for automating administration of Windows systems, as well as to create ASP pages and scripts for Internet Explorer. VBScript is widely used in the creation of scripts in the operating systems of Microsoft Windows.Language - programming language developed to write "scenarios", sequences of operations that a user can perform on the computer. Simple scripting languages ​​earlier is often called batch processing languages. Scripts are typically interpreted rather than compiled (although increasingly adopted compile each time before running). The application, the script - is a program that automates some task that without a script the user would do manually, using the program interface.Script Host (WSH ) - component of Microsoft Windows, designed to run scripts in a scripting language JScript and VBScript, as well as in other additional installed languages ​​(eg, Perl). was created by Microsoft as a replacement for outdated batch language, language, is interpreted by application command.com .. COM - shell in the operating systems DOS, Windows 9x family and several others. Loaded at startup (if no other interpreter with SHELL = directive in the file CONFIG.SYS) and executes commands from the file AUTOEXEC.BAT. br/>
. VBScript scope
in VBScript language mostly used in the following areas, using the products Microsoft:
В· automation of administration of Windows systems;
В· server software code in the pages of the ASP;
В· client scripts in the browser Internet Explorer.type of scenario is typically used for:
В· creation of sophisticated scenarios;
В· using objects from other applications and libraries;
В· hide windows during script execution;
В· encryption scriptlogic.
Mainly VBS - scripts are used for data processing, system management, working with user accounts and computers, interaction with business applications, working with data bases and other sophisticated tasks. - is an ordinary te...
