I have an Excel-file on a p2p network.
It has a password so that most network-users can open it for reading and
only some are able to change it (after they have entered the password).

*** I would like to make certain buttons available only when opened by the
latter and not available when opened "read-only". ***
Any ideas are welcome!

The password is added the "normal" way (Save As + Extra and enter the
password), so it is not programmed in some VBA routine or so (don't even
know if this can be done and this isn't my question either).
