Hm.. I also missed that. :) I think the %lf (note the simple 'l') is the more correct one for double, Specially when it go beyond the float limit '%f' will not work. Currently generated code also use just '%f', that should be corrected. Thanks Dimuthu > > I now have both the client and server working.
