VBScript in a Nutshell 2nd Edition
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.
