Переменная dll C ++ для vb.net exe

У меня есть приложение, которое вызывает и передает аргументы в C ++ DLL. У меня также есть отдельный исполняемый файл, написанный на vb.net, и я хочу передать аргументы из dll c ++ в исполняемый файл vb.net. Я много читал об этом и не могу понять, каким будет лучший способ добиться этого.

Мне не обязательно нужен конкретный код, просто толчок в правильных направлениях поможет.

Вот c ++ dll, мне нужна структура состояний в моем приложении vb.net.
