WM_POINTERDEVICEINRANGE message
Sent to a window when a pointer device is detected within range of an input digitizer. This message contains information regarding the device and its proximity.
![Important]
Desktop apps should be DPI aware. If your app is not DPI aware, screen coordinates contained in pointer messages and related structures might appear inaccurate due to DPI virtualization. DPI virtualization provides automatic scaling support to applications that are not DPI aware and is active by default (users can turn it off). For more information, see Writing High-DPI Win32 Applications.
