protect dvb application

[carry]

Hi.
I created an application consisting of 3 files:
a starting file and two .dvb files, I thought I could protect the whole by craving a .vlx file as described in this articlehttp://usa.autodesk.com/adsk/servlet/item?siteid=123112&id=2765382use visual lisp of autocad 2008 and although there is written in the help that you can load within the .vlx also .dvb file in this there is no choice for this type of file.
I tried to edit the .prv file by replacing the file extension in .dvb
but it doesn't work,
(prv-def)
active-x . t)
separate-namespace . t)
protected . t)
load-file-list lsp "prova.lsp")
require-file-list dvb "prova1.dvb")
ob-directory)
tmp-directory)
optimization . st)
)
; eof
Does anyone have any chances?

Thank you.

Hi.
the procedure described above, incorporating the .dvb files is compiled correctly the vlx file but when the file lisp recalls the .dvb files does not find them, and by error.
It would be interesting to understand how to do it.
in microsoft visual basic however there is in tools -> project properties
the possibility to enter a password for opening files.
