Description
Lightweight yet powerful, VBScript from Microsoft 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 conventionsA list of arguments accepted by the function or procedure, if any existA discussion of how and where the keyword should be used within the scripting environmentA discussion of the differences between the operation of the keyword in Visual Basic or VBA and in VBScriptRegardless 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.
