问题 I've noticed that the running times of my CUDA kernels are almost tripled the moment the screensaver kicks in. This happens even if it's the blank screensaver. Oddly enough, this appears to have nothing to do with the power settings. When I disable the screen saver and let the screen power off, the performance stays the same. When I set the "Turn off monitor" to "Never" and lets the screen saver kick in, it happens. Why does this happen? Is there a way to counteract this phenomena? Is there a

问题 I have a dialog that pops up as result of an error condition. I want the dialog to remain open for at least 30 seconds, and close 30 seconds after the last user input (mouse or keyboard) is received. I can implement this by checking the value returned by GetLastInputInfo and closing the dialog when this is more than 30 seconds ago, but if the dialog pops up when the user hasn't been at the mouse or keyboard for 30 seconds, the GetLastInputInfo test passes immediately, and the dialog closes

What you could do instead is offering the user to give your app control of the lock screen or wallpaper image. UWP apps are able to set these images even
