Trevor,

I'm sorry, but can you please suggest me something - what should I do now?

I've been looking in VPM documentation, I've checked all libraries / forms of this application, I see nothing close to the interface I may need here.

I guess I can probably copy the stuff from the mover form into the container based class, then also copy code (with adjustments) from that class into this new class and then start to use it.

Or I can simply download any good existing mover class and use it instead.

What do you think I should do - I wasted too much time already thinking and contemplating...
