Need some help with this capturing keys

[tmarkovski]

Hello,

I found this little code which basicly writes any keystroke to the app
window, however, it only works for the app window. I wanted to modify
it to work when any window is focused, just like key logger.
I'm too new to C++ to figure out this by myself.
Any help would be much appreciated.

Thanks
