vb-oracle connect

I've set up aconnection between VB and Oracle8.When I start my application ,where I use ODBC DSN to connect, stat databaseoperation fails.Ihave to start the database first from Oracle StartDatabase icon.and then start the application.Only then it works.Is there a way to start the application so that the Oracle database starts automatically.

Maybe you want use function
Shell [your command line]

In [your command line] insert string as in Oracle StartDatabase icon.
