I've built an Access DB for tracking documents for my company and have a number of source tables that are being used to create combo box entry fields on the master form/subforms. Due to the nature of the data being entered, though, fairly often the data needed for the pick list needs added (as we are basically in the initial population stage of the life of the DB) and it is likely that through the life of the DB that functionality will continue to be needed. After updating the source tables though, the only way I know of to get the form to refresh/repopulate the combo box pick lists is to close and reopen the main form where the pick lists are contained. There has to be some kind of routine or command to get the combo boxes to refresh, but I don't know what it is, and the Access resources available at my place of employment have not been able to get me past this one. Anybody have the solution?
