How to find the default icon of a (non exe) file

8 posts in this topic

Hi,

Does anyone know how to get the default icon of a file?

I mean of a file with no embedded icon of course, more precisely for the files for which GUICtrlSetImage() returns 0

I couldn't find a function for this. Or am I wrong?

Check following topic to understand what i mean if my question is not clear enough:

Thanks

hello i came across the same problem, and did it like this.

$tst=_WinAPI_ExtractIconEx($file,0,0,0,0)
                        ConsoleWrite("tst  -->"&$tst&@lf)
                        if $tst<> 0 Then 
                        $index = _GUIImageList_AddIcon($hImage, $file, 0, True)
                        _GUICtrlListView_AddItem($hListView, $str, $index)
                        Else
                        $index = _GUIImageList_AddIcon($hImage, @ScriptDir & "\icons\093_imageres.ico", 0, True)
                        _GUICtrlListView_AddItem($hListView, "No Icon! - " & $str, $index)
                        EndIf

This will not work as a script on its own, but you can get the idea from this.

Bascically test to see if icon can be extracted, if not, add your own icon.

Example:

#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
#include <GuiImageList.au3>

$hGUI = GUICreate("Test GUI", 300, 200)

$cMenu_File = GUICtrlCreateMenu("&File")

$cMenuItem_Open = GUICtrlCreateMenuItem("Open", $cMenu_File)

$cListView = GUICtrlCreateListView("Items", 10, 10, 280, 160)

$hImage = _GUIImageList_Create(16, 16, 5, 3, 1)
_GUICtrlListView_SetImageList($cListView, $hImage, 1)

GUICtrlSendMsg($cListView, $LVM_SETCOLUMNWIDTH, 0, 200)

GUISetState()

While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cMenuItem_Open
            $sFile = FileOpenDialog("Select file", "", "All files (*.*)", 1, "", $hGUI)
            If Not @error Then
                $hIcon = _ExtractAssociatedIcon($hGUI, $sFile)
                $Index = _ImageList_AddIcon($hImage, $hIcon)
                _DestroyIcon($hIcon)
                _GUICtrlListView_InsertItem($cListView, $sFile, -1, $Index)
            EndIf
    EndSwitch
WEnd

Func _ExtractAssociatedIcon($hWnd, $sFile)
    Local $aRet = DllCall("shell32.dll", "hwnd", "ExtractAssociatedIcon", _
                                                 "hwnd", $hWnd, _
                                                 "str", $sFile, _
                                                 "short*", 0)
    Return $aRet[0]
EndFunc   ;==>_ExtractAssociatedIcon

Func _ImageList_AddIcon($hImage, $hIcon)
    Local $aRet = DllCall("comctl32.dll", "int", "ImageList_AddIcon", _
                                                 "hwnd", $hImage, _
                                                 "hwnd", $hIcon)
    Return $aRet[0]
EndFunc   ;==>_ImageList_AddIcon

Func _DestroyIcon($hIcon)
    Local $aRet = DllCall("user32.dll", "int", "DestroyIcon", _
                                               "hwnd", $hIcon)
    Return $aRet[0]
EndFunc   ;==>_DestroyIcon

Very nice example rasim!

Btw, perhaps you should post a Feature Request for _WinAPI_ExtractAssociatedIcon() + change the _GUIImageList_AddIcon() function so it could accept $hIcon, not only a file path, like this for example:

Func _GUIImageList_AddIcon($hWnd, $sFile, $iIndex = 0, $fLarge = False)
    Local $tIcon, $iResult, $hIcon

    $tIcon = DllStructCreate("int Handle")
    
    If FileExists($sFile) Then
        If $fLarge Then
            $iResult = _WinAPI_ExtractIconEx($sFile, $iIndex, DllStructGetPtr($tIcon), 0, 1)
        Else
            $iResult = _WinAPI_ExtractIconEx($sFile, $iIndex, 0, DllStructGetPtr($tIcon), 1)
        EndIf
        
        _WinAPI_Check("_GUIImageList_AddIcon", ($iResult <= 0), -1)
        $hIcon = DllStructGetData($tIcon, "Handle")
    Else
        $hIcon = $sFile ;Handle?
    EndIf
    
    $iResult = _GUIImageList_ReplaceIcon($hWnd, -1, $hIcon)
    _WinAPI_Check("_GUIImageList_AddIcon", ($iResult = -1), -2)
    _WinAPI_DestroyIcon($hIcon)
    Return $iResult
