Keys and Key Codes for Windows Mobile

Windows Mobile 6.5
4/8/2010

Windows Mobile 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 hexadecimal number that identifies the key. Because keyboard layouts vary from language to language, Windows Mobile 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.

The following table shows the symbolic constant names, hexadecimal values, and keyboard equivalents for the virtual key codes used by the Windows Mobile operating system. The codes are listed in numeric order. You can combine any of the codes with a modifier key to create a hot key.

A VK_code is a byte, and so there are only 256 VK_codes total. The virtual key codes listed in the "Virtual key codes" section below are shared with Windows Embedded CE. More virtual keys were required for functionality, and so many hex values are shared between both a traditional Windows Embedded CE value and a Windows Mobile–specific value.

The following table provides a list of the mappings between the traditional VK constants and the additional Windows Mobile–specific value.

Bb431750.note(en-us,MSDN.10).gifNote:
Beginning with Windows Mobile 6.5.3, soft keys are replaced by touchable tiles on Windows Mobile Professional phones.

The following keys were undefined for Windows Embedded CE, but are overridden as application keys in Windows Mobile.

Hexadecimal value Windows Mobile constant

0xC1

VK_APP_FIRST

VK_APP5

VK_APP_LAST

The VK_APP keys will only be recognized by the system if they are wrapped with VK_LWIN. The following code snippet demonstrates how to do this programmatically.

keybd_event(VK_LWIN, 0, KEYEVENTF_SILENT, 0);
GenKeyEvent(VK_APP1);
keybd_event(VK_LWIN, 0, KEYEVENTF_SILENT | KEYEVENTF_KEYUP, 0);

And finally, the following chorded keys are implemented for Windows Mobile.

Windows Mobile constant Hexadecimal value Purpose

VK_DONE

VK_RWIN + VK_F6

<OK/Close> hotkey code.

See SmartMinimize Button.

MOD_DONE

(MOD_WIN | MOD_KEYUP)

<OK/Close> hotkey modifiers

VK_MOJI

VK_RWIN + VK_F7

Key used to switch between East Asian language layouts.

MOD_MOJI

(MOD_WIN | MOD_KEYUP)

Modifiers so MOJI goes to the shell.

VK_A to VK_Z and VK_0 to VK_9 are defined to be the same values as their ASCII counterparts. So VK_A is 0x41 and VK_0 is 0x30. Windows Mobile also defines the following numerical codes.

VK_0 (which is the same as VK_T0) and VK_NUMPAD0 are different keys. On the desktop keyboard, VK_0 is the key just above and to the left of VK_P. VK_NUMPAD0 is the key at the bottom of the number pad on the far right of the keyboard. Windows Mobile applications will always look for VK_0, but can also look for both VK_0 and VK_NUMPAD0 in order to do the correct thing if there was a device with a numpad.

For East Asian Input Method Editors (IMEs) the following additional virtual keyboard definitions must be observed.

Symbolic constant Hexadecimal value Description

VK_DBE_ALPHANUMERIC

0x0f0

Changes the mode to alphanumeric.

VK_DBE_KATAKANA

0x0f1

Changes the mode to Katakana.

VK_DBE_HIRAGANA

VK_DBE_SBCSCHAR

0x0f3

Changes the mode to single–byte characters.

VK_DBE_DBCSCHAR

0x0f4

Changes the mode to double–byte characters.

VK_DBE_ROMAN

0x0f5

Changes the mode to Roman characters.

VK_DBE_NOROMAN

0x0f6

Changes the mode to non–Roman characters.

VK_DBE_ENTERWORDREGISTERMODE

0x0f7

OEMs should not use the unassigned portions of the virtual key (VK) mapping tables. Microsoft will assign these values in the future. If manufacturers require additional VK mappings, they should reuse some of the current manufacturer–specific and vendor–specific assignments.
