Classes deduced from COleDispatchDriver have to
be created for the element and the variables, so that the dispatch
interface of zenon can be used to set values. The easiest way to
create these classes is the Class Wizard of the development
environment (button Add
Class, select From a type
library, select zenrt32.tlb).
For our control theses are the classes IElement and IVariable. They
are defined in zenrt32.h and
zenrt32.cpp.
