I don't think there is a way with RunSQL, which as JCF says, is an Access function, not VB. I would basically change my queries to call public variables if I wanted to pass them parameters and use RunSQL. If I was working with the QueryDef object in DAO, it has a parameters collection. But, once again, it isn't a compiled environment any more than VFP.
