File Icon in registry

[Vindicator209]

Where in the registry can I change the icon for a specific file extention?

For example, if I want the file extension ".msd" to be something like "icon.ico" how can I do this through the registry?

HKCR- You'll need to see the defaul entry for your extention, then go to that key in HKCR where it is under \DefaultIcon

Example: Quick and dirty.

#include "Array.au3"
$filepath = "C:\WINDOWS\system32\user32.dll"
_ArrayDisplay (FileGetIcon ($filepath))


Func FileGetIcon ($file, $opt = 1)
    $string = StringSplit ($file, ".")
    If Not IsArray ($string) Then Return SetError (0, 0, 0)
    $ext = "." & $string[$string[0]]
    $key = RegRead ("HKCR\" & $ext, "")
    If @error Then Return SetError (0, @extended, 0)
    $icon = RegRead ("HKCR\" & $key & "\DefaultIcon", "")
    If @error Then Return SetError (0, @extended, 0)
    
    If $opt = 1 Then
        Local $arr[2]
        $ret2 = StringSplit ($icon, ",")
            $arr[0] = $ret2[1]
            $arr[1] = $ret2[2]
    Else
        $arr = $icon
    EndIf
    Return SetError (1, 0, $arr)
EndFunc
