[DUG] COM object question

[Phil Middlemiss]

Thanks Connor,

I've used a similar method previously with another application and that 
worked fine, but required that the automation class had to import 
another unit for the singleton object (trying to keep it lite). I was 
kinda hoping that there was a global variable in one of the VCL units, 
or a Factory singleton or something that I could refer to from outside 
the automation class' unit.

Cheers,
Phil.
