Win7 VC++ 2008 环境下 Afxmessagebox 问题

Question

 switch(PNum)
    {
    //公共点个数为0时，初始化转换参数为默认值
    case 0:
     AfxMessageBox(_T("请输入公共点参数!"),MB_OK);
     m_Dx = 0.0;
     m_Dy = 0.0;
     m_Dh = 0.0;
     m_T = 0.0;
     m_K = 1.0;
    
     break;

以上代码编译为什么提示

1>c:\users\administrator\desktop\coord_trans\coord_trans\MainFrm.h(903) : error C2065: “MB_OK”: 未声明的标识符
1>c:\users\administrator\desktop\coord_trans\coord_trans\MainFrm.h(903) : error C3861: “AfxMessageBox”: 找不到标识符
1>c:\users\administrator\desktop\coord_trans\coord_trans\MainFrm.h(903) : error C3861: “_T”: 找不到标识符

Answer 1

没包含MFC的头文件。

创建项目的时候没选支持MFC的模板的话，用支持MFC的模板重新创建项目。其他项目模板和MFC差别太大，要加MFC支持太麻烦。

Answer 2

不好意思，版主，再次打搅你，我是在CLR模式下创建的Windows窗体应用程序，但包含#include <afxwin.h>程序还是不行！

这是正常的。用支持MFC的模板重新创建项目。CLR项目模板和MFC差别太大，要加MFC支持太麻烦。

Answer 4

那你就用API，MessageBox得了，具体用法也很简单 MessageBox(NULL, "标题", "正文", MB_OK);只要#include <windows.h>即可。
