I'm trying to use Delphi 4 to display a table in a TDBCtrlGrid. One of the fields in my table is a string field that identifies a logo (graphic), and I want to use a second table to display the actual graphic logo (rather than the logo name). So I created a lookup field in my TTable, set the keyField, lookupKey, ResultField and dataset to point to the second table that maps the logo names to the actual graphics. However, when I try to make my TTable active, I get a DBException, saying that the logo field (my new lookup field) cannot be a lookup or calculated field. Any idea why not?
