No. But the fact remains that it is normally possible to do. There are several third-party programs available that can "look behind" the asteriks of a password entry box and display the plain-text password. My favorite is SnadBoy's Revelation. In fact, at one point, I had even started writing my own TPasswordEdit component specifically to twart such programs while stll providing the owning process access to the password. I never did finish it though, as I moved on to other projects and never got the chance to revisit it yet. > Don't controls "know" their owning process, so could refuse to talk to strangers? The problem with that is it is not possible to determine which process a window message is coming from. Requests for window text have to be processed at the message level, and thus a control would not know whether the request was local or external. Gambit
