Уважаемые мастера подскажите как можно просмотреть кодировку файл [D5, NT4, WinXP]
raptorus © (2004-07-22 07:17:00)для файлов Paradox и FoxPro (и если возможно ее сменить).
Обращение к данным типов файлов осуществляется через BDE Administrator и при изменении кодировки постоянно съезжают русские буквы.
Можно совет,код или линк.
Заранее благодарен.
