For the past month I have been trying to figure out how to get my application to respond to system wide keystrokes.

I can't figure out though how to tell if either a left alt or a right alt has been pressed (same for shift and control).

What I'm trying to do is right a program that when user specified key is pressed, a sound file is played, then an other when it is released (this is to be used with the voip application Teamspeak, providing an audiable feed back when the push to talk key has been pressed or released).


I have looked into registering a hotkey, but it doesn't appear to

a. allow for a 1 key hot key (ie just a left shift)
b. seperate the shift, alt or ctrl keys.


Since teamspeak distinguishes between the left and right keys, I need to be able to do the same.

how?????


I'm currently trying to use a keyboard hook but I'm lost how to tell the difference, though I figure it is hidden in the lparam varable that gets returned - but how do I get that hidden gem?

Just about every example I look at deals with the shift, ctrl and alt keys as if there is only one on the keyboard...

thanks,


Seth
