OEMs should make special note of the VK key ranges reserved for OEM-specific use: 2A, DB–E4, E6, and E9–F5.

In addition to the VK key assignments in the previous table, Microsoft has assigned the following OEM VK keys.

Symbolic constant Hexadecimal value Mouse or keyboard equivalent 
VK_OEM_SCROLL 0x91 
VK_OEM_1 0xBA ";:" for US 
VK_OEM_PLUS 0xBB "+" any country/region 
VK_OEM_COMMA 0xBC "," any country/region 
VK_OEM_MINUS 0xBD "-" any country/region 
VK_OEM_PERIOD 0xBE "." any country/region 
VK_OEM_2 0xBF "/?" for US 
VK_OEM_3 0xC0 "`~" for US 
VK_OEM_4 0xDB "[{" for US 
VK_OEM_5 0xDC "\|" for US 
VK_OEM_6 0xDD "]}" for US 
VK_OEM_7 0xDE "'"" for US 
VK_OEM_8 0xDF 
VK_OEM_AX 0xE1 AX key on Japanese AX keyboard 
VK_OEM_102 0xE2 "<>" or "\|" on RT 102-key keyboard 

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 0x0f2 Changes the mode to 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_ENTERWORDREGISTERMODE 0x0f7 Activates the word registration dialog box 
VK_DBE_ENTERIMECONFIGMODE 0x0f8 Activates a dialog box for setting up an IME environment 
VK_DBE_FLUSHSTRING 0x0f9 Deletes the undetermined string without determining it 
VK_DBE_CODEINPUT 0x0fa Changes the mode to code input 
VK_DBE_NOCODEINPUT 0x0fb Changes the mode to no-code input 
VK_DBE_DETERMINESTRING 0x0fc 
VK_DBE_ENTERDLGCONVERSIONMODE 0x0fd 

OEMs should not use the unassigned portions of the VK mapping tables. Microsoft will assign these values in the future. If OEMs require additional VK mappings, they should reuse some of the current OEM and vendor-specific assignments.

Le keycode (voir ce mot dans ton aide en ligne) de la touche ALT est 18

pulpul74 · Answer

Oui mais donc cela marche avec l'instruction keycode.
Seulement j'utilise l'API 'GetAsyncKeyState' de la dll 'user32.dll'. J'ai tout une liste de touches, dont TAB, CTRL et SUPPR, mais je n'ai pas trouvé ALT.

Autre question: est t'il possible de détecter tout les caractère spéciaux du clavier, comme tout les points, et les caractères jumelés avec les caractère numérique (&,é,"...)
Voila merci de votre aide

pulpul74 · Answer
