Hello,
I am using D2010 and DOA 4.1.2.0.
When trying to write (in a oncalcfields event of a TOracleDataset) in a calculated (string) TField I get the error AV at address 0. Fields are statically defined.
Stepping with the debugger the field seems ok (in the sense that you can see all of his properties, including value) but, if you try to modify the value and then re-evaluate you got the exception even in the debugger.
Is this a known problem ?
I've tested with both a unicode (al32utf8) 11.2 express db and
a 10.2.0.4 (mswin1252) db.
The oracle session has every preference setted to the default.
Only thing I've forced Oracle.NoQueryOptimize := true;
Thanks for any help/tip/ideas.
I access the field in this way:
myField.AsString := my_calculated_value
I've tried also asWideString but with no changes.
Bye
Nicola
