Hi Marco,

You right about this. In Delphi 5 (don't know about Delphi 6) if you declare
a file in the uses clause, Delphi actually link it to the exe file, even if
you do not use it.

It's hard to find it. There's no automatic way to do it. You must delete it
manually from the uses clause and try it. Argh. I found some utilities to do
this using google sometime ago. I really test one or two, but I didn't like
them and I did it manually.

But I think that the DB file that you are talking about it's not BDE
related: it's there to use the TDataset descendants. But I'm not sure about
that.

Just my 2 cts

Artur

Ok, so I turn the question this way:
a) how can I be sure that the code does not use BDE stuff?
b) if it uses it (I mean, if somewhere it's USED, not in the uses clause on=
ly), who can I discover where (in what unit?)?
You know, A.pas could "uses" B.pas that "uses" C.pas that uses BDE stuff an=
d links it to the whole exe.
Thanks
