Why do you have to cast gApplication in ThinkC e.g.:
extern	CApplication	*gApplication;

void main()

{
	gApplication = new(CEditApp);
	((CEditApp *)  gApplication)->IEditApp();
	gApplication->Run();
	gApplication->Exit();
}

if you remove the cast and try gApplication -> iEditApp(), the compiler
complains.
new is meant to "automatically assign a class to the newly created object"
e-mail me if this is too obvious to waste time on the net for!

Thanks
