Not sure of what your asking( so i should probably stay quiet... oh well). But if you're having trouble with the connection string, you can set it up like so:

my $dsn =
 "Driver={Microsoft Access Driver (*.mdb)};" .
 "Dbq=c:\\your_nifty_folder\\your_nifty_db.mdb;" .
 "Uid=admin;" .
 "Pwd=";

my $dbh = DBI->connect("dbi:ODBC:$dsn");

i found that here.
actually this link may better serve you. it discusses inserting binary data into ms access.
i've found this thread w/ code examples of inserting into ms access memo fields
good luck!
