Hi everybody,
We have developed an application using dbExpress driver for MySQL.
Until recently, everything went fine, but ever since we started testing on 64-bit platforms (Windows 2008 Server), the application no longer works.
Through a dependency monitor, I was able to see that an access violation occurs inside the dbexpmda.dll file.
Has anyone had any similar experiences with dbExpress?
I could not find any on the website, but is there a specific version of dbExpress for 64-bit platforms? Is there a specific dbexpmda.dll file perhaps? Are we doing something wrong, or is this a known bug?
Thanks,
Marlon
Application no longer works on 64-bit machine
To solve this problem try to use the Direct mode to connect to MySQL database.
For this you should set the TSQLConnection.ConnectionName property to 'Devart MySQL Direct' value or the TSQLConnection.DriverName property to 'DevartMySQLDirect' and the TSQLConnection.GetDriverFunc property to 'getSQLDriverMySQLDirect' value.

Hi Dimon,
Thank you for your suggestion!
However, I'm afraid I have to report that it didn't work - I've tried changing the properti's you mentioned, but our application still crashes.
As soon as we try to export data to the database, the application crashes. Through a monitoring tool, I can see that the dbexpmda.dll is causing an access violation.
Does anyone have any suggestions as to what we can try next?
Thanks in advance,
Marlon
