Ok Don, that works fine! Thank you very much.
Maybe that will help some others...:
I had to create my event as "\\BaseNamedObjects\Global\EVENT_NAME" in kernel
mode.
Then OpenEvent it with "Global\EVENT_NAME" and it works.
With DevView.exe (something like WinObj.exe), I can see that then event is
created in BaseNamedObjects\Global and it is not duplicatd in the Session.
Have a nice day all,
Francois.
