WHAT THE EXPERTS SAY ABOUT THIS BOOK...
"...it's good to find a title that demystifies everything you need to know about building PowerBuilder 6 web and server applications... The author goes far beyond glancing over the nuts and bolts offering a variety of welcome insights without leaving beginners in the dust."
--www.compbookreview.com
"...it was the author's experience instead of just theory
that gave me new insights into how to better exploit
these technologies."
--Phil Yandl, Application Developer Manager, American Medical Association
"...for experienced PB developers ... it's nice to see that
there aren't several hundred pages rehashing the basics.
It will help propel PB developers into a whole different
arena."
--Michael Hotek, Technical Consultant, Modern Business Technology
"Covers the basics clearly and thoroughly enough for the
beginners while still adding enough deep, technical
details to attract and engage more advanced developers."
--Michael Levine, Senior Developer, University of Illinois
