Trapping keypresses outside of application

[Matt]

Hi all,

I have written a small application that runs from the system tray. I need
to be able to identify when a user has pressed certain key combinations in
any aplication and then respond to them in my app. I have looked into system
wide hooking but it seems very complicated and I have read that this can only
be done using a C# dll. Can anyone help with this or at least point me in
the right direction ?

Thanks,
Matt.

You'll need a keyboard hook to capture these keystrokes system-wide:
