Passing data back to a MaskEdBox?

Would anyone know how to pass data back to a MaskEdBox?
What I'm trying to do is....I want to view an order, so I hit a stored procedure and pass back all the output params....BUT I'm error'n out when I try to pass DateTime & Currency datafields to MaskedBox. Any ideas?

mskCurrency
Format = $#,##0.00;($#,##0.00)
Mask = $###,###,###.##
Passing back a DateTime data

mskDate
Format = mm/dd/yy
Mask = ##/##/##
Passing back a Decimal field


Thanks again......
