Hi, kutupla! Have you tried it yet? I don't know so, but I'd think you don't have to do anything special from what you said you're going to do... i.e. make a front end db w/buttons to other db's. Shouldn't the user get a password prompt when a button is pressed? If the 5 db's have passwords and you do not set them to auto-open using a password, it should prompt them for a password when the button is clicked... no?
I didn't try it myself but I can't imagine it not working.
