John,
Take a look at struct.vcx developed by Christof Lange and Mark Wilden. It
allows you to define a class (based on the struct class) with properties for
each element of the structure. A members property tells the class what the
API expects each member of the structure to contain - integers, fixed length
strings, pointers to variable length strings or almost anything else.
I think it is available on the UT.

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
