[AccessD] Addding a password to a pdf document

Hi all,

I have an Access application that stores a list of email addresses, each one
having a password.
The application has to go through each address, read the corresponding
password, use it to protect a pdf file,
and send it to the recipient.

I don't know wether it is possible  to do it without specific tools. I would
like to use VBA code instead!

Do you have any hint that could help me?

Thanks in advance,

Philippe
