Interfaces, DispInterfaces & Parameter Types

Thanks for the previous replies on type libraries.

I am using only a few of the interfaces in a dll, and the _TLB.pas
file is very large.

a) Do I need to declare _all_ the interfaces in a dll, or can I
declare only those I use (& of course directly related others).

b) I find a number of parameter types declared in dipinterfaces are
not acceptable in my current Delphi 3 (LargeInt, TGUID etc). Must I
have dispinterfaces declared in the _TLB.pas, or can I delete theit
declarations as (AFAIK neither as interfaces nor dispinterfaces) I'm
not using them. Or must I somehow declare an acceptable parametr of
the same size to foil the compiler.

Thanks for any replies.
