Coco
you can not pass objects from a dll to an exe
unless you have them both compiled with
runtime packages.
Delphi's online help describes the process.
Just search the help index and you'll find
the information.
BTW, a dll and an exe are two _disctinct_ executables.
The type information of the one is way different from the other
even when you have a type with the same name, say TButton,
in both executables.
Runtime packages is a solution to this problem.
