has to be done = must be accomplished. Your homework has to be finished before tomorrow.

HAVE AT = attack, attempt. I am tired tonight, but tomorrow morning I will have at my essay assignment.

HAVE ON = wear. I have on a yellow shirt today.

HAVE DONE WITH = finish, cease dealing with. I want to have done with all Chemistry classes-- I just don't understand chemistry.
