The server does not support dynamic attachment of MDF files. You'll have to use a full SQL 2005 database in your application. Go to the MS SQL 2005 page of your control panel to order SQL 2005 databases. You will then be able to attach (copy) your MDF file to the SQL 2005 database.

A sample connection string can also be found in the control panel MS SQL 2005 page after you've activated one.
