Я делаю видео-игру с использованием Microsoft Visual C++, я кодирую все это на языке CLR, но я эту странную проблему ....

Почему-то всякий раз, когда я пытаюсь открыть форму 2 с помощью формы 1, Я получаю эти ошибки ...

Answer 1

Вы получаете сообщение об ошибке, потому что у вас есть циклическая зависимость в файлах заголовки. Ваш компилятор пытается скомпилировать Form2.cpp, где вы включаете Form1.h, в Form1.h вы включаете Form2.h, а в Form2.h вы включаете Form1.h. Вам нужно использовать форвардную декларацию или изменить свой дизайн, чтобы ваш класс был менее связан.

Кроме того, не включают в себя headerfile в себе ..

В целом, вы не должны выполнять свои функции определения в заголовочных файлах, но и использовать свои .cpp файлы для этого. Я также не думаю, что вам нужно использовать предварительно скомпилированные заголовки (stdAfx.h), вы должны отключить этот флажок при создании проекта Visual Studio.

Answer 2

Создайте новый проект. Form1 создается по умолчанию.

Создание кнопки на Form1, дважды щелкните по нему и вставьте код ниже:

Form2^ testDialog = gcnew Form2; 
testDialog->ShowDialog (this); 
delete testDialog; 

Перейти к решению исследователя, щелкните правой кнопкой мыши проект и добавить новую форму и сохранить ее как Form2.

Двойной щелчок Form1.cpp, и вы увидите, что она начинается следующими строками:

#include "stdafx.h" 
#include "Form1.h" 

Редактировать это следующим образом:

#include "stdafx.h" 
#include "Form2.h" 
#include "Form1.h" 

Примечание: Последовательность #include не должна быть изменилось.

Вперед, запустите свой проект и наслаждайтесь !!!!
