If you are just editing a record in an ADO recordset, use Update method:
rst.Update "name of field", "value for field"
If you are going to make the same change to more than one record, consider opening a recordset using a select query sql with only records you need to change. Then add code to make the changes:
Do Until (rst.EOF)
rst.Update "field name", "value"
rst.MoveNext
Loop
Hope this helps.
