I am currently building an application in Access 2000. A system to handle canoepolo turnaments. When I during run time, finishes a match, I would like to close the match data for editing, but leave all the rest of the matches open. I therefore put a yes/no field on the match record. I would then like to check on this field whenever somebody attempts to edit data relating to this record. I need to know what event to add the code to, and I would like to know how to discard changes in VBA code.
