I haven't yet met anybody unhappy about the book, but there are quite a few enthusiastic readers. Here go some opinions from happy readers:
Notes and Domino veteran Richard Schwartz (may the Schwartz be with you!) finds it extremely useful and thinks that there are at least Two Great Reasons To Buy A BookTorben Bang, Notes Developer, SOLAE EUROPE S.A.
...This book and the reference on your web site, has really helped me achieving my first goal in programming the C api from LotusScript.
from a script of ICQ chat with Daniel Nashed (Nash!Com, http://www.nashcom.de)
Daniel: I think it is good to mention that CAPI from lotus script can cause serious crashes if not coded correctly and your book is a great resource for this stuff...
Normunds: resource to create crashes?
Daniel: resource how to code it in the right way :-)
and when I mailed Daniel to ask if it is OK to publish this script, he added:
...this is one of the books to have in the lib :-)
Joe Litton also seems to be happy about the book. Or was it simply the nice stamp on the package that swayed his opinion? Warning: particular kinds of stamps are not guaranteed.
