将 CapsLock LED 用于其他目的

目前我使用以下 autohotkey 脚本通过 CapsLock 按钮更改键盘布局。

SetCapsLockState, AlwaysOff

+CapsLock::CapsLock

#SingleInstance force


CapsLock::Send, {ALTDOWN}{SHIFTDOWN}{SHIFTUP}{CTRLUP}{ALTUP}
; in wind
; Send, #{SPACE}

    return

我希望当布局为波斯语时 CapsLock LED 亮起，当布局为英语时关闭。可以吗？我确实希望在 CapsLock 保持关闭时切换 LED。

有一个图书馆叫键盘 LED 控制可用于切换键盘 LED，与其相应的功能无关。使用此方法并执行类似以下操作：

#Include led.ahk
global PersionLayout := 0

CapsLock::
    Send, {ALTDOWN}{SHIFTDOWN}{SHIFTUP}{CTRLUP}{ALTUP}
    PersionLayout := !PersionLayout
    If PersionLayout = 1
        KeyboardLED(7, "on")
    Else
        KeyboardLED(7, "off")
Return

以下是上述链接中的库，供参考led.ahk：

    KeyboardLED(LEDvalue, "Cmd", Kbd)
        LEDvalue  - ScrollLock=1, NumLock=2, CapsLock=4
        Cmd       - on/off/switch
        Kbd       - index of keyboard (probably 0 or 2)

KeyboardLED(LEDvalue, Cmd, Kbd=0)

  SetUnicodeStr(fn,"\Device\KeyBoardClass" Kbd)
  h_device:=NtCreateFile(fn,0+0x00000100+0x00000080+0x00100000,1,1,0x00000040+0x00000020,0)

  If Cmd= switch  ;switches every LED according to LEDvalue
   KeyLED:= LEDvalue
  If Cmd= on  ;forces all choosen LED's to ON (LEDvalue= 0 ->LED's according to keystate)
   KeyLED:= LEDvalue | (GetKeyState("ScrollLock", "T") + 2*GetKeyState("NumLock", "T") + 4*GetKeyState("CapsLock", "T"))
  If Cmd= off  ;forces all choosen LED's to OFF (LEDvalue= 0 ->LED's according to keystate)
    {
    LEDvalue:= LEDvalue ^ 7
    KeyLED:= LEDvalue & (GetKeyState("ScrollLock", "T") + 2*GetKeyState("NumLock", "T") + 4*GetKeyState("CapsLock", "T"))
    }

  success := DllCall( "DeviceIoControl"

  VarSetCapacity(io,2*A_PtrSize,0)
  VarSetCapacity(pus,2*A_PtrSize)
  DllCall("ntdll\RtlInitUnicodeString","ptr",&pus,"ptr",&wfilename)
  NumPut(6*A_PtrSize,objattrib,0)
  NumPut(&pus,objattrib,2*A_PtrSize)

  return % fh
}

NtCloseFile(handle)
{
  return DllCall("ntdll\ZwClose","ptr",handle)
}


SetUnicodeStr(ByRef out, str_)
{
  VarSetCapacity(out,2*StrPut(str_,"utf-16"))
  StrPut(str_,&out,"utf-16")
}

注意：您可能必须更改 Kbd 的默认值。Kbd=2为了在 Windows 8 中工作， 我必须将其更改为。使用此值直到看到响应（0-5 应该是有效的）。

我认为使用 CapsLock LED 不是一个好主意，这里有一个带有 TrayTip 的示例：

; ListLines, Off
SetCapsLockState, Off
DllCall("RegisterShellHookWindow", "Ptr", A_ScriptHwnd)
OnMessage(DllCall("RegisterWindowMessage"(A_IsUnicode ? "W":"A")
                                         , "Str", "SHELLHOOK", "UInt")
                                         , "ShellMessage")
OnExit, % "ExitScript"
Global bState:=False

~CapsLock::bState:=!bState

ExitScript:
   DllCall("DeregisterShellHookWindow", "Ptr", A_ScriptHwnd)
   ExitApp

ShellMessage(aParams*)
{
   If aParams.1=4 ; HSHELL_WINDOWACTIVATED
   {
      HKL:=DllCall("GetKeyboardLayout", "UInt"
    , DllCall("GetWindowThreadProcessId", "Ptr", WinActive("A")
                                        , "UInt*", 0
                                        , "UInt")
                                      , "Ptr")
      IfEqual, bState, % False, TrayTip,, % "current is: "(HKL&16 ? "fa":"en")
   }
}
