Bonjour/soir,
Tu trouvera une dll qui permet un hook clavier système ici: http://www.mentalis.org/vbexamples/vbexample.php?vbexample=DSKEYBRD&category=MISC Celà devrait répondre à ta question. (A noter que certaines combinaisons de touche système comme Ctrl+Alt+Del ne peuvent être bloquées de cette manière)
Je souhaite pouvoir intercepter la frappe de touche sur le clavier, afin de ne garder que les touches qui m'interresse.
Merci beaucoup

Salut,
Tu peux aussi regarder du coté de l'API GetAsyncKeyState : Declare Function GetAsyncKeyState Lib "user32" Alias "GetAsyncKeyState" (ByVal vKey As Long) As Integer
Avec notamment cet exemple tiré de l'API-Guide :
'In a module Public Const DT_CENTER = &H1 Public Const DT_WORDBREAK = &H10 Type RECT Left As Long Top As Long Right As Long Bottom As Long End Type Declare Function DrawTextEx Lib "user32" Alias "DrawTextExA" (ByVal hDC As Long, ByVal lpsz As String, ByVal n As Long, lpRect As RECT, ByVal un As Long, ByVal lpDrawTextParams As Any) As Long Declare Function SetTimer Lib "user32" (ByVal hwnd As Long, ByVal nIDEvent As Long, ByVal uElapse As Long, ByVal lpTimerFunc As Long) As Long Declare Function KillTimer Lib "user32" (ByVal hwnd As Long, ByVal nIDEvent As Long) As Long Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer Declare Function SetRect Lib "user32" (lpRect As RECT, ByVal X1 As Long, ByVal Y1 As Long, ByVal X2 As Long, ByVal Y2 As Long) As Long Global Cnt As Long, sSave As String, sOld As String, Ret As String Dim Tel As Long Function GetPressedKey() As String For Cnt = 32 To 128 'Get the keystate of a specified key If GetAsyncKeyState(Cnt) <> 0 Then GetPressedKey = Chr$(Cnt) Exit For End If Next Cnt End Function Sub TimerProc(ByVal hwnd As Long, ByVal nIDEvent As Long, ByVal uElapse As Long, ByVal lpTimerFunc As Long) Ret = GetPressedKey If Ret <> sOld Then sOld = Ret sSave = sSave + sOld End If End Sub
