This is an example how to handle exceptions with SEH. But remember. YOU CAN'T HANDLE ALL EXCEPTIONS WITH SEH IN KERNEL MODE ! Use KmdManager to register/unregister and start/stop it. Watch its debug output with the DbgView (www.sysinternals.com) or use SoftICE. Tested under: Windows 2000, XP and Server 2003. Four-F, four-f@mail.ru
