In the tradition of "Java in a Nutshell", this book boils down the essentials of VB and VBA, including undocumented areas essential to everyday programming, into a single volume. The convenient alphabetical reference to all VBA functions, statements, keywords, objects, properties, and methods allows VB and VBA programmers to find exactly what they're looking for in no time at all. .
An excellent extension of the available Microsoft help docs for anyone using VBA for Office automation. Largely a reference index, but there are a few chapters of conceptual explanation. Strictly covers the VBA language, not the VB6 IDE or any particular Office program's automation library. This much-needed specialization of scope is what makes this book so valuable for anyone using VBA; many peer books focus strictly on Excel or Word, or VB6 development at large.
