Lightweight yet powerful, VBScript from Microsoft(r) is used in four main areas: server-side web applications using Active Server Pages (ASP), client-side web scripts using Internet Explorer, code behind Outlook forms, and automating repetitive tasks using Windows Script Host (WSH). VBScript in a Nutshell, Second Edition delivers current and complete documentation for programmers and system administrators who want to develop effective scripts. Completely updated for VBScript 5.6, WSH 5.6 and ASP 3.0, VBScript In a Nutshell, Second Edition includes updated introductory chapters that will help you keep current with the significant changes since the first edition was published. New chapters introduce the Windows Script Component for creating binary COM components, and the Script Encoder. The main part of the book is a comprehensive reference focusing on VBScript essentials with an alphabetical reference to all statements, keywords and objects, and a section of notes and solutions to real-world gotchas--various undocumented behaviors and aspects of the language--to help you avoid potential problems. Each entry in the reference section details the following: * The keyword's syntax, using standard code conventions * A list of arguments accepted by the function or procedure, if any exist * A discussion of how and where the keyword should be used within the scripting environment * A discussion of the differences between the operation of the keyword in Visual Basic or VBA and in VBScript Regardless of your level of experience programming with VBScript, VBScript in a Nutshell, Second Edition is the book you'll want by your side--the most complete, up-to-date, and easy-to-use language reference available.

This guide shows Web developers how to take full advantage of client-side scripting with the VBScript language. In addition to basic language features, it covers the Internet Explorer object model and discusses techniques for client-side scripting, like adding ActiveX controls to a Web page or validating data before sending it to the server. The text is accompanied by a CD-ROM with over 170 code samples.

The online documentation of VB/VBA language components seems to follow the 80/20 rule: the basic facts that you need to use a language statement are provided in the documentation. But the additional 20 percent that you need to use it effectively or to apply it to special cases is conspicuously absent. To a professional VB/VBA programmer, though, this missing 20 percent of the language's documentation isn't a luxury, it's a necessity. And in VB & VBA in a Nutshell: The Language, it finally is available. The bulk of the book consists of an alphabetical reference to the statements, procedures, and functions of the VB/VBA language. Each entry has a standardized listing containing the following information: * Its syntax, using standard code conventions * Differences in the operation of the keyword in a macro environment (e.g., in Office) and in Visual Basic, if there are any * A list of arguments accepted by the function or procedure, if any * A description of the data type returned by a function * The finer points of a keyword's usage that are often omitted from or blurred over by the documentation * Tips and gotchas that include undocumented behaviors and practical applications for particular language elements -- a section particularly invaluable for diagnosing or avoiding potential programming problems * A brief, nonobvious example that illustrates the use of the keyword Also included in VB & VBA in a Nutshell: The Language is a brief overview of the VB/VBA language, including: * Basic VBA programming concepts, such as its data types and its support for variables, constants, and arrays * Error handling in VBA applications * Object programming with VBA * Using VBA with particular applications. Excel and Project are utilized to show how to work with an application's integrated development environment and to take advantage of its object model Regardless of how much experience you have programming with VBA, this is the book you'll pick up time and time again both as your standard reference guide and as a tool for troubleshooting and identifying programming problems. VB & VBA in a Nutshell: The Language is the definitive reference for Visual Basic and VBA developers.
