[AccessD] Array faster in DLL?

Hi Stuart

Sounds great! I think I'll prepare a small test with some of the typical operations I do.
I'm not expecting anyone to do a lot of work to create dlls of my full code. 
First step is to find out how much improvement to expect, then I can consider if it is worth the time to rewrite it.

For something like that I'd definitely build a reall DLL in PowerBasic.
PB has built in array manipulation functions which are highly optimized and 
the speed gains compared to doing this sort of thing in VB/VBA would be 
dramatic.

Create an VB "DLL" is likely to have little effect on speed, it could even 
slow it down because of the calling overhead.

I'm leaving town in a couple of minutes for the weekend, but email me off 
list with your current array procedures and I'll take a look at building a 
simple DLL for you when I get back.
