Look at it this way. You were reporting times in the 15-17 (something) range. Let's say that Hex$ method consumed 14.9 somethings. That would mean that the methods you were trying to time ranged from 0.1 to 2.1 -- quite a vast difference. True, you'll always have to call the other, but don't fool yourself into thinking you learned much about what you claimed to be interested in. > Whether a routine takes 10 'thingies' > or 20 'thingies', it's obvious that the '10' example is faster, > irrespective of how long a 'thingy' itself is. So close! And yet, so far. -- ..NET: It's About Trust! http://vfred.mvps.org

And yet, so far. Did you find the fastest routine, Mike? Well, sure I did, Karl! How'dya do that, then, Mike? Well, gosh durn it, Karl, ya know what? I just stuck in different routines to call until I found one that was fastest! Man, Mike! That sure is gosh darn rootin' tootin mighty clever! Wanna become a Yank? No, Karl. My Queen forbids it. MM

It would never have occurred to me that a Typelib would be that much faster then a DLL declaration.
