Some reviewers here complain some of the scripts dont work, but that's because WSH has been updated since then. After you purchase the book, you can download the scripts from the author's website.
If you are not familiar yet with the concepts of OOP and looking at object models, you might need a primer found in another book before looking into WSH. It is built purely on objects that your code will refence and it can be a bear to take on unprepared.
It will be interesting to see how the .Net framework will integrate the objects in WSH- there is a significant chance that little in this book will be completely valid after Windows XP and Visual Studio .Net have become standard. Nevertheless, this book is an invaluable tool to the Windows programmer who wants to simplify life by automating as many tasks as possible.
When I first got this book, I read a ways into it, decided I didn't have the time or energy to go on, and put it aside. Had I written a review at that point, it would not have been favorable. Then I learned more about the WSH, what it was and what my expectations should be, what a person could do with it - and I picked it back up, and really applied myself. And apply yourself you must for this book. The first 154 pages of this 600 page book teach you the syntax and structure of VBScript (and some JScript). It's a little dry, and easy to get lost in. But once you have that down, the rest of the book can really open things up and show you quite a bit.
Besides an introduction to the language, the book covers "upgrading" your old batch files, writing logon scripts for users, automating network tasks, SQL server, IIS server, as well as showing you how to use ActiveX objects for the file system, CDO, ADO (Database), etc. The book even goes so far as to touch on ADSI scripting for Windows NT and Windows 200 Active Directory.
Even though at this point in time the book is a little out-dated (written in the Windows NT 4 time), it is still a good learning tool. Not so unlike other "... in 21 days" books, the average person won't complete the book in that time, and you learn just as much correcting the errors in the code and doing the workshop material as you do from the actual guided lessons. If you're looking for a scripting solution that is quick and easy, WSH and VBScript isn't it, and neither is this book. If you're looking for a powerful automation tool for network and services automation, and you're willing to spend the time it will take to complete this book, then this could be the title for you.
