用vc++编计算器程序时在定义一个CEdit类的子类MyEdit的成员变量m_DspEdit时有了下面的警告，

please ensure that "My calculator Dlg.h"contains the necessary #include directive(s) for using your CMyEdit(form 

file"MyEdit.h")
以上是警告，编译完有好多下面的错误（各位高手帮帮忙吧，谢谢了）

追问：加上之后出了下面问题
c:\documents and settings\owner\桌面\计算器\mycalculator\mycalculatordlg.h(6) : error C2018: unknown character '0xa1'
\mycalculator\mycalculatordlg.h(6) : error C2018: unknown character '0xa1'
mycalculator\mycalculatordlg.h(6) : fatal error C1083: Cannot open include file: 'CMyEdit.h': No such file or directory
MyCalculatorDlg.cpp
\没有把，因为我是看着书按书上步骤做的，书上说用ClassWizard建个新类CMyEdit 基于（Baseclass）CEdit.然后增加成员变量m_DspEdit,完成了点确定时就出了上面的警告，编译完成出了好多错误，是不是没加什么头文件啊？

答案：在你的mycalculatorDlg.h
里加上#include　"MyEdit.h""

其他：成员变量类型定义错误了吧，看看自己写错了没 编辑框拥有一个标识，比如叫IDC_XXX_XXX,设置CEdit型变量，比如m_edit，是VC6.0为例，查看— 删掉加的类试试，看是代码问题，还是VC问题

上一个：看这个VC ++ 2010 程序怎么不能编译啊,
