Я пытаюсь создать визуальное базовое консольное приложение для 3D-программы САПР Solid Edge, в этом консольном приложении я хочу, чтобы Visual Basic делал в нем кривые. Я хочу сделать эти кривые с помощью уравнения 4-й степени. Данные, используемые для уравнения, хранятся в текстовом файле с разделителями-пробелами. В текстовом файле есть несколько строк с разными данными, каждая строка используется для составления уравнения 4-й степени. Теперь я попытался сделать программу, но она застряла на создании кривых линий, консоль просто остается черной и не закрывается. Программа подключается к программе и открывает среду 3D-моделирования.
Кто-нибудь знает, что я делаю неправильно в своем коде или что мне делать вместо этого? Я использую стандарт Visual Basic 2003 года. Я не программист, но я пытаюсь автоматизировать работу программы 3D CAD.
Вот мой код:
