I have the Developers Handbook and find it difficult to follow (being a
relative beginner at some of this).  I have also downloaded DeBaets
windows manipulation tools which is only good to demonstrate how
ShrinkerStretcher works.  I intend to purchase ShrinkerStretcher at some
point but already know I can't get it here in time to solve an immediate
problem.

I need the procedure/code for resizing if I develop a program using
800x600 setting but am giving/selling the program to someone who may
have different settings.

Can anyone help (quickly) so I can just be done with this problem and go
from there?

Thanks.
