You'll need a Union query. Something like:
SELECT Field1 FROM MyTable
Union
SELECT "<All>" AS Field1 From MyTable
If you use the value of the combobx in another query, you'll need to change
the criteria to something like:
IIF(Forms!MyForm!cboSelection="<All>", [TableFieldName],
Forms!MyForm!cboSelection)
What this does is say, "if you selected All, match the field name to itself,
thus returning all records. If it's not All, filter for the value selected."
