I don't believe this book should be considered a "Developer's Guide", since it is a very poor reference book. Perhaps it wasn't meant to be a reference, but any Developer's Guide should have a robust reference section. The VBScript Reference section is very poorly laid out and difficult to read. The topics are extremely difficult to pick out, everything runs together. More intelligent use of font sizes and indentation (much like writing code) would have made it much more readable.
The proofreading wasn't very comprehensive either. There are numerous spelling errors within the syntax examples, and some outright incorrect entries. Example: on page 437 under the "CreateTextFile Method" heading, the syntax example shows CreateFolder, not CreateTextFile. Also, instead of tables showing the various parameters of the various methods a descriptive paragraph is given instead. The grammar is terrible. Here's a snippet: page 456
"...You can open the file for reading, writing, or appending. You use a 1 to open a file for read-only. The data in the file can only be read. You cannot write to this file. If you want to open the file for writing, you use a 2. That means you will write to the file, but you cannot read the file. If you want to append to the file you use a value of 8. When you append to a file, all writes are added to the end of the file."
This is a VERY inefficient paragraph, and it's indicative of many paragraphs in the book. It would have been much more efficient, from a developer's standpoint, to have a parameter table with explanations next to each parameter. The above paragraph doesn't indicate whether there are other values that can be used with the specified parameter. I didn't find this to be a Developer-level book at all.
