This script receives notifications from WinLIRC whenever you press a button on your remote control. It can be used to automate Winamp, Windows Media Player, etc. It's easy to configure. For example, if WinLIRC recognizes a button named "VolUp" on your remote control, create a label named VolUp and beneath it use the command "SoundSet +5" to increase the soundcard's volume by 5%.

; 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 or later. ; HISTORY OF CHANGES ; 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.
