Is Firebird supposed to be able to work with standard InterBase
components that come with C++Builder 6 (eg: IBTransaction IBDatabase
etc.) and if so, how?

I have Firebird 2.0.3 and Borland C++Builder 6.0
I can create a Firebird database and tables with ISQL.
But I can't get any of the Borland InterBase components, the Borland
Database Desktop v7.0 or SQL Explorer v4.00 to work with Firebird. They
only work with InterBase (when I turn it on)

I haven't tried using ODBC yet, as I presumed the IB components would
have worked directly. Is there a client API that I need to import
instead? Have just noticed IBObjects stuff, as well. Do I need to use
these instead of the InterBase components?

Thanks in advance
