Как вызвать функцию другого класса в заголовочном файле

---

Я новичок в C++/Cli, так что голый со мной.

Итак, у меня есть класс узла (page3_node.h), page3.h (страница формы) и page3.cpp который состоит из реализации page3_node.h. моя проблема в том, что я пытаюсь получить доступ к методам page3_node.h в page3.h, но я не могу этого сделать. Любая помощь будет очень признательна.

вот три файла.

Что я уже пробовал:
