Dear Andrey,

please would you be so kind and send me the full version of dbExpress driver.

We bought the driver on 13th January (company KP-SYS)

But official downloads doesnt enable to download version 4.3.5 - there is 4.3.4 from october only.

Or can you upload new version for official download??

My demo version licence is over and I can't work!!

Thank you in advance

Tom

How to make read-only transaction?

To solve the problem, please try to specify the exact path to the client library of your Firebird. For example:

Code: Select all

SQLConnection1.Params.Values['VendorLib']: = 'C:\Program Files\Firebird\Firebird_3_0\fbclient.dll';
