What i am trying to do is, i would like to control this three mdb's in one single switchboard without having to shar all the tables,forms and etc in one apllication. To be more clear, let say i created an application call, Switch.mdb,which contains a button for ledger.mdb,courseware.mdb,assets.mdb , and by starting the switch.mdb,i can click any buttons to start either three mdb.Do you get what i mean?PLease help
