Hi,

Not exactly sure what the Connect String you refer to is.

I am using Delphi with a dbexpress connection. The driver and
connection files are as follows:

Driver

[FireBird]
GetDriverFunc=getSQLDriverINTERBASE
LibraryName=dbexpint.dll
VendorLib=FbClient.DLL
BlobSize=-1
CommitRetain=False
Database=
ErrorResourceFile=
LocaleCode=0000
Password=masterkey
RoleName=RoleName
ServerCharSet=
SQLDialect=1

Connections
DriverName=FireBird
BlobSize=-1
CommitRetain=False
Database=C:\Project Data\NAC New IB6\NAC_NEW_IB6.gdb
ErrorResourceFile=
LocaleCode=0000
Password=masterkey
RoleName=RoleName
ServerCharSet=
SQLDialect=3
Interbase TransIsolation=ReadCommited
User_Name=sysdba
WaitOnLocks=True

The Connections file refers to the Firebird driver. I had to use
the old Interbase definitions and make some mods. As you can see the
Driver refers to getSQLDriverINTERBASE as I had no idea what to use.

It actually all worked fine when the database server and client were
on the same PC.
