[DUG] ClientDataset and Key Violation

[Matthew Comb]

You need build 668 to be exact, 666 was the last version to come with
Delphi.

Matt.

Hi Rohit,

There is a bug in one of the versions of the midas dll which causes an
error when you have inserted over 35 records without applying updates.
I can't remember the exact number.

If you go to Dan Miser's website he generally has a copy of the latest
DLL there to download. They are fully backwards compatible and has had
a number of fixes. Perhaps the DLL versions are different between
workstations.

You could also try compiling you app with MidasLib in the uses clause
- which removes the need for deploying the DLL (but means you can't
use newer versions of it). If you aren't already doing this. I believe
MidasLib is in D7.

cheers,
Jeremy
