I'm running Win7 64-bit and Firebird 2.5.2. Is it possible to access a 32-bit Firebird database via ODBC from a 64-bit C++ application? My initial thought was that I could just install the 64-bit Firebird ODBC driver and it would work. Sure enough, after installing it the 64-bit ODBC control panel app shows the Firebird driver, but the connection fails when trying to point it to an.fdb file created with 32-bit Firebird. I'm picking the client library from the 64-bit firebird install as well (C: Program Files Firebird Firebird_2_5 bin fbclient.dll).

Any suggestions on accessing a 32-bit Firebird database via ODBC from a 64-bit C++ application? EDIT: My bad, looks like its working fine.

I must have accidentally mixed some 32- and 64-bit pieces of the config when setting things up. Once I ensured that I was 1) running the 64-bit server, 2) using a 64-bit ODBC data source which 3) referred to the 64-bit client DLL (from the 64-bit Firebird install) my 64-bit C++ app connected with no issue. I thought I checked those but I must have missed something in going between 32- and 64-bit.
