C#/WPF hotkey on a not focused form (like launchy)

问题:

Is it possible to catch a hotkey (eg. Ctrl+Space) from a not focused form, to make it appear whenever someone uses this specific hotkey ; And without having to register this hotkey on the registry. A similar event can be noticed in the application "Launchy".

Thank you

You need to call the RegisterHotKey API function.
Here is a WPF wrapper.

I think you will need to do that in the Active form by handling KeyDown Event
