I am trying to detect whenever a specific key is released, without focusing on the application.
I use GetAsyncKeyState, but it detects whenever the key is beeing pressed and not when it is released.

Joel those just detect while the application is beeing focused, what if it is minimized? – user3383786 Mar 07 '14 at 14:31

Doesn't GetAsyncKeyState tell you if it is up or down? – Rob Mar 07 '14 at 14:34

@user3383786 I'm asking what kind of application you have. It matters a great deal to the answer, as it changes what api's are readily available. – Joel Coehoorn Mar 07 '14 at 14:36

Oh And WIndows form application, that's right. – user3383786 Mar 07 '14 at 14:46

@Rob It doesn't detect when it is released – user3383786 Mar 07 '14 at 15:01

You need to hook into the keyboard if you want to detect keystrokes (or releases) outside of your application having focus. See this post for how to do that. http://stackoverflow.com/questions/15038413/how-to-listen-keyboard-in-background-and-fire-keystrokes-on-demand – John Mar 07 '14 at 15:05

@user3383786 if it isn't down ... it's up. – Rob Mar 07 '14 at 15:25
