I have several sub EXE that are being call by another EXE. That main EXE holds several functions. In each of the sub EXE, in order to avoid the unknown references at compile time, I added the following in my main program of each of those projects:

DEFINE CLASS dummy as Object
FUNCTION TreeView
RETURN .F.
FUNCTION TreeViewFooter
RETURN .F.
...
ENDDEFINE

So, whenever I add a new function in the main EXE, I have to update each project in that main program. How can I avoid that?
