System message hook?

[Eric Johannsen]

Is it possible to write a system hook in C#? I have seen a few posts
claiming that it's not possible. The justification given is that the system
hook has to be in a relocatable DLL, and that this can not be accommodated
in .Net.

What I'm actually trying to do is figure out when a certain key is pressed
and inject a number of additional key events into the system event queue.

Thanks!

Eric

The code project links have complete samples you can look at. Post back if
you still have questions.
