You mean you're doing Namespace Extension, correct? If it is the case, do you use IImageList inside your codes?

I just noticed that you've posted a solution to your own question. The code you posted below looks weird to me. Have you solved your problem?

it's my example on Delphi

Delphi

function GetImageListSH(SHIL_FLAG:Cardinal): HIMAGELIST;
type
  _SHGetImageList = function (iImageList: integer; const riid: TGUID; var ppv: Pointer): hResult; stdcall;
var
  Handle: THandle;
  SHGetImageList: _SHGetImageList;
begin
  Result:= 0;
  Handle:= LoadLibrary('Shell32.dll');
  if Handle<>S_OK then
  try
    SHGetImageList:=GetProcAddress(Handle, PChar(727));
    if Assigned(SHGetImageList) and (Win32Platform=VER_PLATFORM_WIN32_NT) then
      SHGetImageList(SHIL_FLAG, IID_IImageList, Pointer(Result));
  finally
    FreeLibrary(Handle);
  end;
end;

procedure TFmMain.bTestClick(Sender: TObject);
var
  ImageList: HIMAGELIST;
  Ico: TIcon;
  Res: Integer;
begin
  if odPicture.Execute then
  begin
    ImageList := GetImageListSH(SHIL_JUMBO);
    Ico := TIcon.Create;
    try
      ico.LoadFromFile(odPicture.FileName);
      Res := ImageList_AddIcon(ImageList,Ico.Handle);
      ShowMessage(IntToStr(Res));  //Res always equal -1
    finally
      ico.Free;
    end;
  end;
end;

Solution 3

ImageList_Replace (-1,HIcon) will add an icon to the END of the ImageList...
