<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>On 99% of the installations this runs smooth, but
some customers get a function error at this statement on Mac and Win. The
curious thing on this is, that it only happens since my latest update release.
And it happens reproducible at this some customers every time they launch my
app. When installing an older version of my app, it runs without this problem.
But since the beginning of this app I have nothing changed on this function or
statement.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>So there are two questions: 1. What could be the
difference in the environment of the machines, where it runs and not, what
could have an effect on this statement? 2. What could have changed in my App
from one version to the next that this error appears, but only on a few
machines? My only idea is, that perhaps the valentina drivers or my program
isn’t fully or correctly loaded. But is so, why and what could I change?
Does anybody has experienced anything similar and has any hint or direction for
my researches?<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>2. With the first version of my App I got on some Mac
machines an index error. So I added a VDataBase_SQLExecute( gDBRef,
"REINDEX DATABASE" ) after having opened the database and the problem
was gone.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Because my database has no write or update actions on
it (it is only read by my App), the database file resides in a subfolder of my
program dir, what was no problem concerning any user rights for write action.
Now I got unsure, what actually is happening with the reindex database. Is this
a write performance on the database file or does the reindex only happens in
the memory? If it is a write performance on the file I think it should not
resides in the prog dir, but 1. I can’t change the whole design of my App
at all customers out there and 2. If this could get a problem, why is it
running at all (most) customers? 3. Could problem #1 has anything to do with
this, though the reindex happens a dozens statement later as the test of being
open and no error is thrown on this statement.<o:p></o:p></span></font></p>

don’t see the wood for the trees.<o:p></o:p></span></font></p>
