Just wondering if anyone out there has experienced a HUGE number of differences between the code given in the Book and the code offered online? What I don't understand is that the online code is wrong and the printed text is correct... now why doesn't someone from wrox just update the online code - it's not as though there are any reprinting costs...

Have you submitted an errata report to them?

I'm not submitting any eratta reports... I bought the book with the assumption that the online code and the code in the book are identical. Where the code differs, I would assume that the online version is updated to reflect errata in the printed version. Any other difference is unacceptable and pointless, and the result of poor proof reading (if any) Take for example the issue of the '.' (full stop or period). In the book it is used frequently to wrap long pieces of code across a number of lines whereas the online code need not do this so doesn't include the periods. Great, you might think. But this obfuscates the teaching point by adding a layer of unnecessary complexity.

In short, I#ve only reached Chapter 4 and have found that the book is uninspired, poorly written and lacking clear explanation with the early chapters offering little concrete knowledge but deferring to the more in depth later chapters... shabby.

Ok maybe not errata then but they certainly need to make aware of these issues.
