Crystal Reports in VB.Net Project--Date Format??

[wtfman]

I am using the following formula to populate a 'Data Date' range: formula = "Data Dates from " + totext(minimum({@closed time})) + totext(maximum({@closed time}))
When I run it in Crystal and exprt to pdf the date format is MMDDYY hh:mm but when I run the report using vs.net 2003 the date format changes to YYMMDD hh:mm. How can I specify the format to stay MMDDYY hh:mm??
