Hello
First of all I think you are in the wrong newsgroup. Messaging is not meant
for Windows messages but instead for the messaging system as used for e-mail
etc.
Same is true for the guy up there asking about HWND_BROADCAST.
Someone else may correct me if I'm wrong.
Anyway, here is that what I know:
- ENDSESSION: I don't think there's a reason to distinguish them. In both
cases Windows will be shut down. Applications should behave exactly the same
if there is a shutdown or a restart. You should use the policies to
configure what a user can do. (I don't know much about policies though.)
- Logon: Windows controls who can log on. If you want to interfere with this
mechanism *before* someone logs in, you have to use the security system
somehow. You can't use windows messages for that.
