I am was the official reviewer for this book before it was published. I was not paid for this service, nor do I benefit in any way from the sale of this book.
The book starts with a basic introduction to the programming environment, and includes a brief introduction to the structure of the language. The book does not even attempt, however, to provide full coverage of the language. This is not an introduction to programming or Basic. If you know something about programming, however, this should be sufficient to get you started.
The chapter on the object model, discusses how [...] (OOo) structures its internals. More specifically, the use of interfaces and services. There is also a discussion on how to manipulate the sheets and cells, which is what you probably expected when you see Object Model.
I refer to this book as Eclectic, because it contains numerous different topics, some of which you will not likely find elsewhere. For example, the book contains a fully working macro that extracts stock values from a web site to populate a Calc document. The macro even creates a chart over time of the stock.
Another nice offering in this book, is coverage of the FuncationAccess service. This service allows you to call the standard built-in functions such as STDEV from a macro. This is frequently a skipped topic, and you will not find it in the online help pages.
Although I could spend time to provide a chapter by chapter description of everything that is covered, well, that is not my intention. I primarily wanted to mention that I consider myself very well versed in Macro Programming, and I learned a few things by reading this book, and I enjoyed the process!
