Francisco,

Are you sure you need to send two arrays to the function? The first one containing 19 empty strings and the second one containing 100 empty strings? Or do you need to pass one string of 19 characters and one string of 100 characters to the function?

If it is the second case:

local wserie AS String
wserie = space(19)

local wIDRegistro AS string
wIDRegistro = space(100)

DECLARE INTEGER VFGenerateId IN VFinger.dll String, String
wres=VFGenerateId(wserie,wIDRegistro)
