Thanks for your reply. But I dont know how does this solve my problem.
Actually we use sysbase database. They have there own drivers. What i
just need to do is While connecting to database, i want to provide all
the parameters needed to connect. connection string e.g. driver (here
driver would be the full path of the dll rather than just
"ODBC;DRIVER={sql server}"), it would be like this Driver=C:/program
files/dbms/abc.dll , database server name, password etc. All the links
which u have mentioned directly/indirectly depend on registry. What i
want to do is connect to db without registry. it would be possible
that we dont want to install the driver and just use it. Is it
possible? it should be just plug-in and play sort of.

Thanks

No, those links don't depend on the registry.. They all talk about how to set the
connection string in Access using VBA. Same idea for other apps.

Well, you're going to need drivers of some sort, be they built into the OS or
installed.

I'd suggest asking in a sysbase (or is that Sybase) newsgroup.

ODBC does not support "registry free" connections. There are two types
of ODBC registries: one for DSNs (Data Source Names) and one for
Drivers. You can have a DSN-less connection, but you must specify a
registered driver name instead. You do this with SQLDriverConnect()
and the DRIVER property. You can't use the path to the driver .dll to
connect.
