Thanks Helen, and Claudio
Well the situation is more complex than the function I put, it was only to
say I need timestamp as a parameter and a return value, my real functions
have to do more than adding one day, so I need dlls. I'm not sure it's the
time for me to move on to FB because I'm not sure there's no other way. I'll
check my work again and might post it if I still don't get it to work.
regards
Omar
