Hi! I need to create an application that captures keystrokes, even if minimized. I want to create a control for calls where no matter what app the user is using, my control can see when the next person was called. Can anyone help me?

What you are trying to do is a kind of Keylogger and will be recognized by the Antivirus.
You can build a DLL for that, for using the hookproc.
I don't even know about it on another system than Windows.
More info:

That's right, I've used this DLL once on Windows, but now I need to use this feature on Linux and I haven't found anything about it. The case of this DLL works only on Windows.
