Открытие стандартного окна выбора папок/файлов |

Расположите на форме TextBox и CommandButton.
При нажатии на кнопку вы получите доступ ко всем
папкам и файлам компьютера. Вы можете ограничить
возможность выбирать только папки. Наличие BIF-констант в вызываемой функции и
определяет такие возможности по выбору.
