Microsoft® Windows® CE maintains a device-independent keyboard model that enables it to support a variety of keyboards. At the lowest level, each key on the keyboard generates a scan code when the key is pressed and released. The scan code is a hardware-dependent number that identifies the key. The keyboard driver translates or maps each scan code to a virtual-key code. The virtual-key code is a hardware-independent number that identifies the key. Because keyboard layouts vary from language to language, Windows CE offers only the core set of virtual-key codes that are found on all keyboards. This core set includes English characters, numbers, and a few critical keys, such as the function and arrow keys. Keys that are not included in the core set also have virtual-key code assignments, but their values vary from one keyboard layout to the next. You should depend only on the virtual-key codes that are in the core set.
