WinLIRC 客户端

每当您在遥控器上按下按钮时此脚本会接收到来自 WinLIRC 的通知. 它可以用来自动操作 Winamp, Windows Media Player, 等等. 它配置起来很简单. 例如,如果 WinLIRC 能识别您遥控器上名称为"VolUp"的按钮,那么创建名为 VolUp 的标签并在它后面使用命令 SoundSet +5 来增加声卡 5% 的音量..

; Here are the steps to use this script:
; 1) Configure WinLIRC to recognize your remote control and its buttons.
;    WinLIRC is at http://winlirc.sourceforge.net
; 2) Edit the WinLIRC path, address, and port in the CONFIG section below.
; 3) Launch this script. It will start the WinLIRC server if needed.
; 4) Press some buttons on your remote control. A small window will
;    appear showing the name of each button as you press it.
; 5) Configure your buttons to send keystrokes and mouse clicks to
;    windows such as Winamp, Media Player, etc. See the examples below.

; This script requires AutoHotkey 1.0.38.04 or later.
; HISTORY OF CHANGES
; March 2, 2007:
; - Improved reliability via "Critical" in ReceiveData().
; October 5, 2005:
; - Eliminated Winsock warning dialog "10054" upon system shutdown/logoff.
; - Added option "DelayBetweenButtonRepeats" to throttle the repeat speed.

; -------------------------------------------------
; CONFIGURATION SECTION: Set your preferences here.
; -------------------------------------------------
; Some remote controls repeat the signal rapidly while you're holding down
; a button. This makes it difficult to get the remote to send only a single
; signal. The following setting solves this by ignoring repeated signals
; until the specified time has passed. 200 is often a good setting.  Set it
; to 0 to disable this feature.
DelayBetweenButtonRepeats = 200

; Specify the path to WinLIRC, such as C:\WinLIRC\winlirc.exe
WinLIRC_Path = %A_ProgramFiles%\WinLIRC\winlirc.exe

; Specify WinLIRC's address and port. The most common are 127.0.0.1 (localhost) and 8765.
WinLIRC_Address = 127.0.0.1
WinLIRC_Port = 8765

; Do not change the following two lines. Skip them and continue below.
Gosub WinLIRC_Init
return

; --------------------------------------------
; ASSIGN ACTIONS TO THE BUTTONS ON YOUR REMOTE
; --------------------------------------------
; Configure your remote control's buttons below. Use WinLIRC's names
; for the buttons, which can be seen in your WinLIRC config file
; (.cf file) -- or you can press any button on your remote and the
; script will briefly display the button's name in a small window.
; 
; Below are some examples. Feel free to revise or delete them to suit
; your preferences.

VolUp:
SoundSet +5  ; Increase master volume by 5%. On Vista, replace this line with: Send {Volume_Up}
return

VolDown:
SoundSet -5  ; Reduce master volume by 5%. On Vista, replace this line with: Send {Volume_Down}
return

ChUp:

if ActiveClass in Winamp v1.x,Winamp PE  ; Winamp is active.
    Send {right}  ; Send a right-arrow keystroke.
else  ; Some other type of window is active.
    Send {WheelUp}  ; Rotate the mouse wheel up by one notch.
return

ChDown:
WinGetClass, ActiveClass, A
if ActiveClass in Winamp v1.x,Winamp PE  ; Winamp is active.
    Send {left}  ; Send a left-arrow keystroke.
else  ; Some other type of window is active.
    Send {WheelDown}  ; Rotate the mouse wheel down by one notch.
