>Thanks, Andrew. It's intriguing, don't you think, that it is a propert for DBSETPROP().

DBSETPROP is merely a programmatic way to do (most) everything you can do in the table and view designer. If you look at the first page of the table designer, on the bottom of the page, you can specify a "Display Class" to be used when a field is dragged to the form. The "DisplayClass" property for DBSETPROP is just a programmatic way to do that.
