datetime as sp output parms

[mushin]

Trying to retrieve datetime's via output parms in sql 7 stored proc.The other parms (varchar/int) work fine.

***** VB code snippet *******

Dim objCmd As New ADODB.Command.....

objCmd.Parameters.Append _
objCmd.CreateParameter("admission_date", adSmallDateTime, adParamOutput).....

*****spoc code snippet **********
CREATE PROCEDURE sel_admission_test
(@pt_id varchar(25),@admission_sequence integer,@last_name varchar(25) output,@first_name varchar(15) output,@admission_date smalldatetime output)
as........

******************?????*************

is "adSmallDateTime" Valid ?
admission_date is defined as smalldatetime.

do I need a length like the others and if so what, I tried 8
cause dates are 8 bytes.....???

I don't do a lot of vb/sql so be mericiful.....
