Summary: Worth the money?
Review: The real question with a book like this is - is it worth the money?

The book markets itself as a 'quick reference' book, so you would hope it would provide value over and above what you can find in the help files.

Unfortunately, I did not find this to be the case. There was little info that the help files wouldn't tell you. Some of the information seemed out-of-date or lacking.

As examples:

IIF - The book claims you need to distribute an extra DLL to use this function (which is not the case with VB 6). It also fails to mention the classic pitfalls of IIF (slowness, and the fact that the valueIfTrue and valueIfFalse parameters are evaluated regardless of the value of expression).

IsEmpty - This function is described as 'Determines if variable is empty' - not very helpful. Then, the examples suggested do not even include a line where IsEmpty evaluates to True. The writer would *appear* to believe IsEmpty("") is True, which is a grievous error.

IsError - Like IsEmpty, the description is again not very helpful. Plus, again, the example (IsError(13)) evaluates to False. There is no indicaton of what the expression would need to be for IsError to evaluate to True.

IsMissing - No mention is made that as of VB 6, this should only be used of optional parameters of type Variant.

With so many errors in the space of 20 pages (of a total of 450), I really can't justify expenditure on this book. Read Books Online instead.

Summary: Excellent command set reference!
Review: This is an excellent quick reference for the VB6, VBA and vbscript command sets! The annotations for which comands are available to vbscript were especially helpful to me. Well worth the $14 or so.

Summary: Updated with even more info!
Review: With this update, I not only added new information about VB 6, but also:

* New How-To code section for code examples of common operations such as updating a database, using VB to automate sending mail through Outlook, etc.

* New object models and examples for ADO, File System Objects, and ASP.

* Hungarian notation chart

* and more!

Since the last edition was a bestseller, I spent even more time refining this new edition. I think you'll find it useful.
