手动编程的WinForm对话框编译错误 [英] Manually programmed WinForm dialog box compile error
问题描述
嘿，伙计们.我对于手动编程Windows还是很陌生的，但我一直陷在这个问题上.我正在尝试遵循本教程: http://www.winprog.org/tutorial/dialogs.html [^ ]
直到我尝试添加对话框之前，程序窗口都可以正常显示.该对话框使用"menures.rc和menures.h".我在主文件中包含menures标头，并停止了未声明的"错误.我想现在我需要在主要函数中声明"IDD_ABOUT"和"ID_HELP_ABOUT".但是，我不知道如何.预先感谢您的帮助.
错误是:"[在这里符号]"之前的预期主表达式
我在发生错误的地方旁边放置了注释.
MAIN.CPP(不是完整的代码，所以如果需要更多代码，请告诉我)
Hey, guys. I''m VERY new to programming windows manually and I''m stuck on this problem. I''m trying to follow this tutorial: http://www.winprog.org/tutorial/dialogs.html[^]
The program window came up fine until I tried to add the dialog box. The dialog box uses "menures.rc and menures.h". I included the menures header in the main file, and that stopped the "undeclared" errors. I guess now I need to declare the "IDD_ABOUT" and "ID_HELP_ABOUT" in my main function, or something. But, I have no idea how. Thanks in advance for the help.
The error is: expected primary-expression before ''[symbol here]''
I put notes next to where the error occurs.

推荐答案
您可能需要在文件顶部#include "resources.h".
下载 Thinking in C ++ 2nd Edition by Bruce Eckel [
You probably need to#include "resources.h"at the top of the file.
Download Thinking in C++ 2nd Edition by Bruce Eckel[^], it will explain some things you''ll probably need to know.
Good luck :)
