3.0 out of 5 stars Not as good as I expexted. July 8 2002
By odoe
The one major flaw this book has, which someone else touched on was that the author does not thoroughly explain what is happening in the code. Being a VB developer, I still found myself scratching my head in some areas. Also, it is hard to tell if the errors in the code are intentional or typos. If you copy the code out of this book to the letter, your program will not work properly. For example on page 116 one line of code reads, "If lstlayers.Count > 0 Then". This code SHOULD be "If lstlayers.Listcount > 0 Then".
Mistakes, or learning tools like this are very annoying, but seeing as my choices for a book on MapObjects is between this and another book, which has not faired too well in it's reviews, it will have to do. If you are new to Visual Basic, I suggest you learn the basics before delving into MapObjects...this book requires it, although it does attempt to show you very basic things.

1.0 out of 5 stars Nearly useless Jan. 20 2004
Poorly written, very confusing and error plagued. The author's intentions are great but he misses his goals entirely. Unfortunately, the book is a waste of money.

I am currently learning ESRI MapObjects 2, and was recommended this book as it was quite tough to really understand the vast object model of MapObjects 2 through the samples alone. This book gives quite a good explanation of the MapObjects 2 object model.
However, be warned of a few things - Some of the explanations are terse and you wish the author spent some more time to explain them. Also, there are some mistakes in the code printed in the book (I prefer typing down the code to learn rather than looking at it on the CDROM). For the intermediate level VB programmers, there are better ways to code some parts of a project than mentioned in the book. For example, in Chapter 5, where the author uses a cumbersome method to split a filename - something that can be done in 3 single lines. A final thing I disliked was the editing/format of the print. It would be a lot better to print the code in a better manner (to make it really apart from the rest of the text), and also the indenting and spacing between lines in the code. The code looks like one long sentence in some places, making it a little difficult to read.
Otherwise this book is a good source, and something that you will want to refer to while coding MapObjects - but do not blindly follow the bad coding habits, try to use your knowledge to accomplish the task in a better way once you have understood the MapObjects model.
