Re: use psqlodbc on Windows without Windows driver manager?

Hello Takayuki,

thanks for your reply :-)
Calling the ODBC driver via driver manager requires the driver to be
installed in Windows (means: written in the Windows registry). But a
test distribution of our (ODBC-)application should be able to run
without the need of any installation procedure and without administrator
rights.
IBM's DB2-CLI (call level interface) can be operated in 2 modes: with or
without an ODBC driver manager. So i hoped that the PostgreSQL ODBC
driver has this ability, too.

Kind regards,
Dieter Mueller
