We use an encryption system from NetLib and would like to put the frontend password on the encrypted command line used to open the frontend and avoid the user getting prompted for it.
The reason for having the ability to hide the frontend password in an encrypted program is to avoid making the password public. Once you have the password to a database you can remove all security from it including things like a startup form or macro. See:
Using another database to open the frontend via Office Automation just kicks the can down the road. You can hack that one and then the frontend.
The password can be hidden in a very small program that shells a command line to open the database. The password can be encrypted in the program and decrypted at the time the shell command is issued.
