I've been trying to create a fast connection to a local MS Access database
using ADO components in BCB5. When inserting records into a very small test
db for insertion speed measurement, I got 17 seconds for 1000 records using
ADO-Jet 4.0 to with MS Access. Comparing to 0.7 seconds with IBX and IB6
MSAccess seems pretty lousy. Am I doing something wrong or is it reality?
Vassiliev, I tried to use your components as well, but didn't manage to
create a connection (jet4-MS Access) due to an "authorisation problem" which
I didn't understand.
Thanks for any help on using MS Access as dircectly as possible and as fast
as possible.
regards,
Markus
