这是什么错误啊
我看是说告诉我已经在 Mncheck1.obj里定义了
可我在Mncheck1.cpp和.h文件中都没有定义呀

错误是变量重复定义，是不是在 .h 文件中定义了全局变量？一般的做法是在某个 .cpp 中申明全局变量。然后在相应的 .h 中用 extern 申明此全局变量。

[E17]

在 stdafx.h 里面 是不是定义了

[xxx94x]

是啊，我是在stdafx.h里定义了

[In355Hz]

CString strco；// 改为

extern CString strco;

// 然后在 stdafx.cpp 中定义：
CString strco;

我照你说的方法改了，可错误依旧在啊
.cpp

// stdafx.cpp : source file that includes just the standard includes
// Project.pch will be the pre-compiled header
// stdafx.obj will contain the pre-compiled type information

#include "stdafx.h"

CString strhc;
CString strno;
CString strpower;
