Использование функции SHGetFileInfo |
|
| |
Данный пример позволяет из пути к файлу узнать имя файла, а также описание типа зарегистрированного файла, и еще 3 параметра, смысл которых я не уловил. Вам и карты в руки, если вы узанаете смысл получаемых параметров, напишите.
Const MAX_PATH = 260

End Type
