SetWindowsHookEx() WM_KEYBOARD_LL not coming through with full screen RDC

I'm trying to do a away timer style thing like Skype. If the user is 'away' for a period of time I'll trigger something. I have been using SetWindowsHookEx() with WM_KEYBOARD_LL which works fine. That is until you open a RDC connection and have it full screen. Then I never get the keyboard events.

Anyone come across this? Or know of a better way to achieve this? I have actually tested skype and with a full screen RDC it will correctly go from Away to Online if I type in the RDC.

Thanks

EDIT: After Raymond Chen's comment I did some testing, and he is right. Can not believe I never found this method after all my searching. It also solved an issue I was having with a WPF app not triggering the LL_Mouse/KEYBOARD events.

Thanks Again. Update my accepted answer based on this. The other answer is still good if you need to do LL_MOUSE/KWYBOARD.

Solution

  • Have a look at GetLastInputInfo(). Try calling that periodically.
