And about what "faster" version are you talking about? (there are more then 1 "faster" routines posted there. Anyways, everything posted in that thread works perfectly.
If you're talking about
my routines, the fastest there are and easiest to understand (as they are almost 1 to 1 copies of the original C++ routine) then it is strait forward and very easy Visual Basic, there is nothing difficult about it; they are even much easier to understand then all the other crappy VB routines out there...
Oh and btw, the code from Ginge (the one you added as an attachment in this thread) is also buggy and will return wrong values for certain emailaddresses. So, even more a reason to remove the attachment; the only bugfree VB routines are the ones I posted...
