choosing access db instead of project data(dataset)

[seco]

Hi

I choose Create New Connection -> Access/Excel (DAO)

i use the full path of the database because i can't enter the database name only because it gives me error message although the db in the same directory with my program
and when i put the program on diffrent machine it prompts me to enter username and password for the login although the database has no password !! and this because the full path of the database changed on the second machine of course.
and the database server points to the full path on the old machine.
so any solution ?
and Here is my source code

thanks in advance.
