how to use the named event in driverstudio

I read the help,it mentioned that there are three methods to communicate between driver and application,I tried first two, but I can't realize the third,that is -- named event,I first allocate the event in the driver,then I initialized it,I can use it in the driver, but when I use openevent() to access it in application,it returned the error code 2,that is "can't find the file" why?If somebody tried successfully, please let me know .Thanks a lot.

Hi,
 I do not know which operating system you use,The win98 name event do not support the name event.

I use win2k. But I tried it out. What a pity, It's no use for me.It can't use the event's method set() or reset() in ring3.Thank you still.

If the os is win2000, you can create event in application,
then you open it in driver. It works very good .
You can try it again.
Good luck with you!

one of the articles post by the manager of this board,
< How to comunicate between app and driver>, he give a example, u can ref. to it.

1. Wrong SECURITY DESCRIPTOR will cause a driver created event inaccesable in application. Don't use default SD for the event.
2. \\BaseNamedObjects is the directory your event should resides.
