Overview Imagine having the ability to write code quickly and easily in a text editor without having to worry about complex development environments Imagine not having the hassles of compiling code or distributing complex set-up programs Imagine being able to deploy your code in a wide variety of ways Imagine learning one language that allows you to code for server-side Internet, client-side Internet, and desktop Stop imagining VBScript gives you all this and much more VBScript is an absolutely superb language to be able to 'speak' in It's quick and easy to learn, powerful, flexible, and cheap This makes it a winning language for both experienced programmers and those starting out in their programming careers If you are an experienced programmer you can enjoy writing code free from complex development environments and the need for compiling On the other hand, if you are a beginner you can get started programming, needing nothing more than a little knowledge and a text editor Knowledge and experience in VBScript can open many technology doors too Having a good grounding in VBScript can lead you into areas such as Internet development, network administration, server-side coding, and even other programming languages (Visual Basic being the most popular route to take because the languages are so similar in syntax) With VBScript you can also create applications that look and feel like programs written using complex programming languages, such as C++ Also worth bearing in mind is that support for scripting is now embedded into every installation of the newer Windows operating systems-a dormant power that you can tap into with VBScript know-how By writing some simple script in a text editor you can a variety of tasks-such as copy and move files, create folders and files, modify the Windows registry, and lots more One easy-to-use scripting language can it all We believe that VBScript is a skill that many people will find both useful and rewarding, no matter whether they are involved in the IT industry, a SOHO PC user, a student, or simply a home user Knowing and using VBScript can save you time and, more importantly, money Team LiB Team LiB Who This Book Is For This book is the one-stop book for anyone who is interested in learning VBScript How you use it depends on your previous programming/scripting knowledge and experience: If you are a complete beginner who has heard about VBScript and have come this far, it's great You've come to the best possible place As a beginner you have a fascinating journey ahead of you We suggest that you go through this book from cover to cover to get the best from it If you already have IT and programming experience and want to learn VBScript (perhaps for Active Server Pages (ASP) or Windows Scripting Host (WSH)) then you too have come to the right place Your background in programming will mean that you will already be familiar with most of the terms and techniques we will be covering here For you, the task of learning another language is made simpler by this If you know what you plan of using VBScript for (say ASP or WSH), then you can read with this in mind and skip certain chapters for speed Network administrators are likely to find this book not only useful, but also an enormous timesaver because they can use VBScript to write powerful logon scripts or automate boring, repetitive, time-consuming, and error-prone tasks using WSH You're already using VBScript and just want to fill some of the blanks or bought this new edition just to keep right up to date You will no doubt find new information and you might want to read certain chapters more than others Team LiB Team LiB What This Book Covers As you'd expect, a book on VBScript covers VBScript To be precise, this book covers VBScript right up to the latest version (version 5.6) However, VBScript is a tool that can be used in a variety of different ways and by a variety of different applications Therefore, along with covering VBScript in detail, this book also covers technologies that are linked to and associated with VBScript These include technologies such as server-side technologies like Active Server Pages (ASP), client-side Dynamic HTML (DHTML), and Windows Script Host (WSH) Likewise, if you come from a Visual Basic background then most of what we will cover in the first third of the book (variables, data types, procedures, flow control, and so on) will be familiar to you We'll also show you how to get deep into the Windows operating system and make changes with just a few lines of code Team LiB Team LiB How This Book Is Structured Take a quick look at the table of contents of this edition and you will see that it is broken up into three broad sections: First, the book begins with chapters that are core VBScript-basically how VBScript works as a language Second, the book looks at how to make use of VBScript within other technologies (such as WSH or ASP) These chapters look at more advanced examples of VBScript code in action Finally, the book has a detailed and comprehensive reference section in the form of a series of appendices This reference section can be used either as a standalone reference section or to give you greater insight into how the VBScript from earlier chapters works How you decide to progress through the book really depends on your current skill level with regards to VBScript or other programming languages and what you want to If you want to use VBScript client-side on the Web then you can; if you want, skip any or all chapters relating to server-side VBScript On the other hand you might be a server-side developer and not be currently interested in client-side VBScript Again, that's just fine It's your book-use it the way that is best for you If you're not sure as to the best way to approach this book, we suggest that you read it from beginning to end, so that you benefit fully Don't worry too much about actually remembering everything you read-that's not the point The book is a reference, which means you can refer back to it again and again Make notes in the book as you go along, as this will help you remember better and also help you to find key parts you've read before Team LiB Team LiB What You Need to Use This Book VBScript is possibly a low-cost solution to many of your scripting/programming needs The good news is that if you (and your end users) use a Microsoft Windows operating system, you already have everything you need to be able to make full use of this book (or you can go online to download it) All the code writing that you will be doing can be done using the Windows Notepad application that you already have installed We will make a few suggestions as to other tools you can use that may make life easier for you, but a text editor is all you really need The Microsoft Scripting Web site contains documentation relating to VBScript that is available for download You may like to download these too to augment your reading here If you are not using Windows XP you might want to download the latest VBScript engine-point your browser at http://www.microsoft.com/scripting Team LiB Team LiB Conventions To help you get the most from the text and keep track of what's happening, we've used a number of conventions throughout the book Note Boxes like this one hold important, not-to-be forgotten information that is directly relevant to the surrounding text Tip Tips, hints, tricks, and asides to the current discussion are offset and placed in italics like this As for styles in the text: We highlight important words when we introduce them We show keyboard strokes like this: Ctrl+A We show file names, URLs, and code within the text like so: persistence.properties We present code in two different ways: In code examples we highlight new and important code with a gray background The gray highlighting is not used for code that's less important in the present context, or has been shown before Team LiB strType, data types of REG_BINARY, 336 REG_DWORD, 336 REG_EXPAND_SZ, 336 REG_SZ, 336 strUserName argument, 84, 86 strWorkingDirectory, 358 Style object, 293 Sub keyword, 83, 84
