Good book from two perspectives: if you use AppForge for Palm development then this is a complete (slightly dated) book, or if you use MS VB6 for conduits or Palm-flavored web applications with IIS. Almost everything in the book is backed up with running code.
As an aside, I am not sure if the previous reviewer actually read the book or tried to run the code. There are very few typos in the chapter mentioned (which is online) and I didn't see any errors. For me, the code worked fine; the book specifically mentions VB6 and service pack 3.
