setting path of database for report during runtime??

hi everybody!

Is it possible to specify a database-directory for a report during
runtime???

I have written a little application where the user can specify
the directory for a database. The name of the database and the structure
of the database is not varied, only the path where the database can be
found. But how can I "tell" a report-file created with the Report-Smith
where the path of the database is?????

thx in advance
