I’ve got a question about lock the OS in the kernel mode,which looks like
the win2k normal locking dialog in the Ring3.Is there anybody who can give
some help for me? some links are all ok.
You shuldn’t at all lock the whole kernel. U’d rather use dedicated spin
locks or critical sections.
And? You can’t open dialog boxes fromout kernel mode. OK, there must be
some way, win32k is also here, but this is not intended.

I dont know if someone here has the experience of writting VxD. My purpose
is doing the work like
SHELL_SYSMODAL_Message function does.
I’ve customize my GINA.dll,which pops up the locking dialog automatically
when specified event occurs.
But the system is still running. Is there any way to do the same work as
SoftIce does? Not for debug,just
block the system.

Why on earth would you even want to do this? It just sounds like a bad
idea.
What are you trying to achieve?

I am implementing an encryption/decryption fs filter driver. Both the
algorithm and user information that the filter driver need are built in a
USB key.
When the user pull out the key by accident, my filter driver can not go
down. Even worst, user’s encrypted file will be corrupted. So, this is my
reason.
thanks a lot. Do u have another better way for this?

Ming

You have to deny access to encrypted file without a key. Look at EFS.
Eugene.
Then IoRaiseInformationalHardError is a way.
