I keep getting this error message when trying to connect usinq IBSQL:

ISC ERROR CODE:335544375
ISC ERROR MESSAGE:
unavailable database

I am using the latest Firebird embedded version and can connect easily
to the fdb file with IbExpert.

When using IBSQL I point to the database file ...\DB.fdb with
Username SYSDBA & password masterkey. I have both fbclient.dll &
gds32.dll in the same directory.

What am I doing wrong?

Thanks
