I do this doing the following as my filter in the view:

Normally you would set it up as:

Table.DateField = ?vp_date

and the vp_date would have to be a date, but you can do this:

DTOC(Table.DateField) = ?vp_date

Then the vp_date can be a character string and thus can be blank to find all records. Try this and let me know.
