[AHK2] FileAssociate() - Works with Win10

12 Sep 2018, 16:37

Change PlayerPath and EditorPath to paths of executables that can run mp3 files, and run the script.
Type "/useplayer" or "/useeditor" (anywhere) to change which program is associated with mp3 files.

Example usage is shown in the script, you can associate any extension with anything, but you can't associate directly to a path, paths must be stored in a label, and then you can associate an extension with that label (which can all be done in 1 line).
There is currently no way to automatically revert changes made, it has to be done manually, so use at your own risk.

I tested the script and it works fine... for me ...be my guinea pig.

Code: Select all

	PlayerPath:="C:\Program Files (x86)\The KMPlayer\KMPlayer.exe"
	EditorPath:="C:\Program Files (x86)\Audacity\audacity.exe"
	StarIcon:=A_WinDir "\System32\shell32.dll,-44"
	RecycleIcon:=A_WinDir "\System32\shell32.dll,-32"
return

:?*:/UsePlayer::
	iF FileExist(PlayerPath)
	{
		;Create a new label
		FileAssociate("CustomPlayerLabel",,PlayerPath)

		;Associate extension with an already existing label
		FileAssociate("CustomPlayerLabel",".mp3")

		;Changes icon of label (explorer requires restart)
		FileAssociate("CustomPlayerLabel",,,StarIcon)
		
		TrayTip("Using Player for mp3 files")
	}
return

:?*:/UseEditor::
	iF FileExist(EditorPath)
	{
		;Create a new label, associate the extension with it, and then change its icon
		FileAssociate("LabelForEditor",".mp3",EditorPath,RecycleIcon)
		
		TrayTip("Using Editor for mp3 files")
	}
return

/*
Associating extensions to uncompiled ahk scripts can be done like this:
FileAssociate("AutohotkeyScript",".mp3",'"C:\Program Files\AutoHotkey\AutoHotkey.exe" "C:\Script.ahk" "%1" %*')

"HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ext\OpenWithProgids"
"HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ext\UserChoice"

Registry values (variables) that are changed:
"HKEY_CLASSES_ROOT\.ext\(Default)"

Registry values (variables) that are created:
"HKEY_CLASSES_ROOT\Label\(Default)"
"HKEY_CLASSES_ROOT\Label\DefaultIcon\(Default)"
"HKEY_CLASSES_ROOT\Label\Shell\Open\Command\(Default)"
"HKEY_CLASSES_ROOT\.ext\BackupOpenWithProgids\*" this has no use, it's just a pointless backup

".ext" refers to the extension that you are changing, and "Label" is the label in which the run command is stored.

Re: [AHK2] FileAssociate() - Works with Win10

I tried compiling this script.
Used this as the function:
FileAssociate(Label:="AutohotkeyScript",Ext:=".ahk",Cmd:="%A_WorkingDir%\AutoHotkeyU64.exe",Icon:="")

Receiving an error. I'd like to do a 1 time install for a program that will automatically associate autohotkeys with AutoHotkeyU64.exe, but it gives a missing % error on a ton of lines, including the comments. I'm pretty sure this is a compiler error though.

Otherwise appears to work fine for non .ahk extensions.

Hello!

I made a spin-off for AHK v1.1.

Code: Select all

      Try {
         If A_IsCompiled
            Run *RunAs "%A_ScriptFullPath%" /restart
         Else
            Run *RunAs "%A_AhkPath%" /restart "%A_ScriptFullPath%"

         ExitApp
      }
  }
}

Hope it works! Should be used with compiled scripts running in Admin mode.

Best regards, Marius.

In the end, i discovered, this function is not enough. Windows 10 prevents using a security hash the change of certain file formats association solely by registry gimmicks.

Code: Select all

FileAssociate(Label,Ext,Cmd,Icon:="", batchMode:=0) {
; by Ħakito: https://autohotkey.com/boards/viewtopic.php?f=6&t=55638 
; modified by Marius Șucan to AHK v1.1

  ; Weeds out faulty extensions, which must start with a period, and contain more than 1 character
  iF (SubStr(Ext,1,1)!="." || StrLen(Ext)<=1)
     Return 0

  ; Weeds out faulty labels such as ".exe" which is an extension and not a label
  iF (SubStr(Label,1,1)=".")
     Return 0

  If Label
     RegRead, CheckLabel, HKEY_CLASSES_ROOT\%Label%, FriendlyTypeName

  ; Do not allow the modification of some important registry labels
  iF (Cmd!="" && CheckLabel)
     Return 0

  regFile := "Windows Registry Editor Version 5.00`n`n"
  ; Note that "HKEY_CLASSES_ROOT" actually writes to "HKEY_LOCAL_MACHINE\SOFTWARE\Classes"
  ; If the command is just a simple path, then convert it into a proper run command
  iF (SubStr(Cmd,2,2)=":\" && FileExist(Cmd))
     Cmd := """" Cmd """" A_Space """" "%1" """"
  Else
     Return 0

  Cmd := StrReplace(Cmd, "\", "\\")
  Cmd := StrReplace(Cmd, """", "\""")
  regFile .= "[HKEY_CLASSES_ROOT\" Ext "]`n@=" """" Label """" "`n"
  regFile .= "`n[HKEY_CLASSES_ROOT\" Label "]`n@=" """" Label """" "`n"
  regFile .= "`n[HKEY_CLASSES_ROOT\" Label "\Shell\Open\Command]`n@=" """" Cmd """" "`n"
  regFile .= "`n[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\" Ext "\UserChoice]`n""ProgId""=" """" Label """" "`n"
  regFile .= "`n[-HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\" Ext "\OpenWithProgids]`n"
  regFile .= "`n[-HKEY_CLASSES_ROOT\" Ext "\OpenWithProgids]`n`n"

  If Icon
     regFile .= "`n[HKEY_CLASSES_ROOT\" QPVslideshow "\DefaultIcon]`n@=" Icon "`n`n"

  If !InStr(FileExist(mainCompiledPath "\regFiles"), "D")
  {
     FileCreateDir, %mainCompiledPath%\regFiles
     Sleep, 1
  }

  iExt := StrReplace(Ext, ".")
  FileDelete, %mainCompiledPath%\regFiles\RegFormat%iExt%.reg
  Sleep, 1
  FileAppend, % regFile, %mainCompiledPath%\regFiles\RegFormat%iExt%.reg
  runTarget := "Reg Import """ mainCompiledPath "\regFiles\RegFormat" iExt ".reg" """" "`n"
  If !InStr("|WIN_7|WIN_8|WIN_8.1|WIN_VISTA|WIN_2003|WIN_XP|WIN_2000|", "|" A_OSVersion "|")
     runTarget .= """" mainCompiledPath "\SetUserFTA.exe""" A_Space Ext A_Space Label "`n"
  FileAppend, % runTarget, %mainCompiledPath%\regFiles\runThis.bat
  If (batchMode!=1)
  {
     Sleep, 1
     RunWait, *RunAs %mainCompiledPath%\regFiles\runThis.bat
     FileDelete, %mainCompiledPath%\regFiles\RegFormat%iExt%.reg
     FileDelete, %mainCompiledPath%\regFiles\runThis.bat
  }

  return 1
}

This is the function i ended up with. It makes use of SetUserFTA.exe developed by Christoph Kolbicz from http://kolbi.cz/blog/2017/10/25/setuserfta-userchoice-hash-defeated-set-file-type-associations-per-user/
