John,
In General and off the top of my head,
DLL VFP
Handle Integer
Array String
ULONG Long/Integer
Int Integer
In short anything that is a pointer set up as a string and anything numeric
like define as an integer as your first step.
Sorry I can't be more specific without my Laptop with me!

Subject: Help with data types needed
Hi Guys,
I need help again! I've been asked to do a job which involves calling API
functions from a supplied DLL. I've never had to use the DECLARE statement
from scratch before, I've always been able to blag someone else's code <g>.
The prototype in the dll documentation refers to INTVAL, STRVAL, INTREF,
STRREF, LONGREF and LONGVAL. The help file for DECLARE refers to INTEGER,
SINGLE, DOUBLE, LONG and STRING. Which should I use for what?
TIA
