Beginning Valentina Question

Thanks, Mark, but it appears to me that the problem probably lies in 
Revolution's sample stacks. Neither of the database samples works when 
used with Valentina.

I visited the valentina site and found a reference to the issue of what 
is returned when a Valentina DB is opened. According to the post I read 
there, the docs are wrong in indicating that an integer is returned 
from a valid database opening. Rather, an empty value returned 
indicates success. So I changed the appropriate line in the script to 
look for empty rather than not a number. Now the software DB demo loads 
correctly without an error dialog but any attempt to add a new software 
item generates a new error dialog indicating a connection error.

I don't know how one is supposed to work through this kind of thing 
with documentation that is wrong or missing or, worst of all, 
contradictory. But apparently a lot of folks have gotten Valentina 
databases working with Revolution. So maybe it's the demos that are 
wrong rather than the revolution interface. Maybe the demos are out of 
date and need updating or fixing.

Anyway, I'm giving up trying to get the demos to work and seeing if I 
can figure out how to get *any* SQL command to execute in Valentina. 
This feels like skating on very thin ice. When the tools don't work as 
advertised, everything in programming becomes a crap shoot.
