Can pass the machine's MAC at authentication 1st step so that the 2nd app gets authenticated automatically if 1st app has authenticated (note that other apps will authenticate on same machine that way, plus that a MAC address can be changed on various hardware and software platforms, so not that secure) For IPC can use TCP sockets even on a local machine (no firewall gets in between local connections usually). Can also use shared files or pipes on UNIX and Windows (in the 2nd OS better download the latest version of "Services for Unix" [for Windows] from MSDN). With Windows can use shares, memory mapped files, Windows messages (e.g. WM_COPYDATA) and other methods and on *NIX too there should be other methods too ---------------- George Birbilis ([EMAIL PROTECTED]) Computer & Informatics Engineer Microsoft MVP J# for 2004-2006 Borland "Spirit of Delphi" ++ QuickTime, Delphi, ActiveX, .NET components ++ http://www.kagi.com/birbilis ++ Robotics ++ http://www.mech.upatras.gr/~Robotics http://www.mech.upatras.gr/~robgroup _____ avast!
