I'll simply ignore those facts :-)
If someone is building with set pieces, they'd better keep to the pieces and
colors, or get lost...
Seriously, if we want that functionality, then I think the modeller itself
must keep track of everything - it's too much to put into a communications
protocol.
Perhaps you could put MLCad into 'set mode', which makes it impossible to
change the colors, or add arbitrary pieces...
As an (perhaps better) alternative, MLCad could be the program reading the set
description, and then cross-reference the current piece count with the set
each time a piece is added or re-colored (refuse to add pieces not in the set,
of the wrong color, no more left, etc.). You already have the mechanism for
creating inventory lists of the model.
In this way LDList doesn't have to keep track of anything...

Don't forget: In Windows, everything is done with messages! So, whatever is
done with the high-level thingys in MFC (OLE etc.) is in reality done with
plain window messages!
