Each short is a 2-byte integer. So, you need to pass a string of 6 bytes. For the conversions from VFP numerical type to short 2-byte string:

lcJour = chr(lnJour % 256) + chr(int(lnJour / 256))
lcMois = chr(lnMois % 256) + chr(int(lnMois / 256))
lcAnnee = chr(lnAnnee % 256) + chr(int(lnAnnee / 256))

And pass the lcJour+lcMois+lcAnnee to the DLL function.

Probably you already knew how to do this, but...
