Closed DataSet

2007-11-23 07:32:41 PM
I've got two programs using the same database file. They do not do that
simuntanuesly. The file is a dbase format. And some BDE, Borland Database
Engine, are LANGDRIVER = ascii Ansi, Level = 4.
if I use application A, only, and A again it goes ok
if I use application A and then B then it goes ok.
if I use application B, only, and B again it goes ok
but if I use B and then A on the same dbf file it goes wrong.
In the latter case that goes wrong, I get a closed dataset message, on an
Append statement.
When I then look at was is changed in the dbf file, it seems A does not want
to go on, if the second byte has a value of 07. Application B does not seem
to mind that. If I change that bit with a hex editor to 6B, Application A
goes running smoothly again.
Hence any idea what this bit is indicating? It probably indicates the
dataset is closed, or locked, or used? But I seem to shut off everything
finishing 'B', so what the hell has it corrupted?

Mwa, solved it, there was something wrong with my BDE setting, they were not
ansi ascii, like in the manual and probably like App A had to work.
