As an update from Carl's VB 4 version of this book, it seems not to come that far. New VB 6 internet technologies have not been detailed about, mainly WebClasses. How the book can be called Visual Basic 6 I don't know.
But apart from its lacking in covering the latest technology it is a very, very useful book. Carl takes you through building programs for different protocols (NNTP, FTP, HTTP) and demonstrates how to build programs to access News servers, FTP servers, Web servers and Mail servers. This detailed information is worth the price of the book.
In the book Carl uses a third party control a lot, which is a shame because we all want to see how it can be done using the Winsock contol. Somebody commented that the code could easily be applied, but that's not why you buy a book. Perhaps if Carl had written his own internet control for use in this book it would have been a bit more credible, although the book does included a good description of the Winsock contorl and how it works.
If you are looking for a start in internet programming, or want to refresh your memory on the bulk of internet programming, then you should buy this book. But if you are wanting to learn the latest internet technologies included in VB 6, then look elsewhere.
