Вот только, вероятно, придётся какой-нибудь header подключить (а какой - не знаю
). Насколько я помню, в Delphi функция ExtractIcon была импортирована в модуле ShellAPI, так что вероятно и в C++ Builder'е будет какой-нибудь заголовок с похожим названием.Обе эти функции находятся в shell32.dll и имеют имена ExtractIconA и ExtractIconExA соответственно, поэтому, если что - то ты можешь импортировать их самостоятельно.
