У меня есть приложение, которое подключает Windows VPN (не OpenVPN) с помощью интерфейса rasphone.exe.Я могу успешно установить соединение, но каждый раз запрашивает пароль.Есть ли способ заставить интерфейс запомнить пароль, чтобы в случае потери соединения оно могло автоматически восстанавливаться программно?Как примечание, когда я запускаю процесс для rasphone.exe, я получаю исключения, когда пытаюсь передать ему более 1 параметра.Единственный параметр, который я могу успешно передать - это имя записи, я не могу добавить такие параметры, как -d, -h или -f.
Вот код, который у меня есть:
