Why I can't receive WM_INPUT message when I locked my system or go to the switch user UI? RRS feed

  • Question

  • I had implemented an application by using the RegisterRawInputDevices API to receive WM_INPUT message , and then my application can get the raw data from our input device , it worked fine when our application was in connected state, but when I locked my system or went to the switch user UI, then our application couldn't get WM_INPUT message anymore. Can I know why ? Is it the limitation for this message?
