Register Global Hotkey in Windows CE

i search for a method to register for a global hotkey, so i can trigger a method when the key gets pre开发者_开发知识库ssed.

It needs to work with Windows CE and Windows Mobile >=5.

[EDIT: It also needs to work when the application is hidden and/or the form has no focus]

If RegisterHotKey fails to do what you want for some reason, put in a keyboard hook. Hooks aren't "officially" supported, but for the keyboard they work just fine.

You can use RegisterHotKey function defined in coredll. On the devbuzz forum you can find a post called: code for c# hotkey register/unregister which shows an implementation

Another method is to run a separate thread and call GetAsyncKeyState in a loop with an acceptable Sleep time. GetAsyncKeyState should be independent of keyboard focus.

You can use RegisterHotKey function
