Keylogger problem (some characters)

generatioZero (10)
Hello, I have this keylogger code.. works fine.. but I have a problem to get characters 'composed', for example @ (in my keyboards is Alt Gr and ò button.

How can I get extra characters? for example created with Ctrl + Alt + etc etc.. ?

For @I tried to add number 64 but didn't works.. is logged just Alt Gr..
some ideas?
