vb.net - How to get data from access database where date is selected from a date/time picker? -


the database i'm accessing has columns : (id, orderid, sandwich, price, , orderdate). orderdate column format date , time. here's code:

mycon.connectionstring = consl     mycon.open()     try         dim sql string = "select count (*) [hestiasales] [sandwich] = '" & lbldr.text & "' , [orderdate] = #" & orddt.text & "#"         dim cmd oledbcommand = new oledbcommand(sql, mycon)         dim dr oledbdatareader = cmd.executereader         while dr.read             qty = dr.item(0)         end while         cmd.dispose()     catch ex exception         msgbox(ex.message)     end try     mycon.close()

i've tried using orddt.value didn't work, code working fine before added date lines. every time run code says "data type mismatch in criteria expression". ideas? edit: i've date syntax include "#" , no longer previous error, 0 query result, despite having correct time picked either textbox or 'datetimepicker' date "27/03/2017 16:00:
