MFC中文件及目录操作

//mfc 中删除dir目录下的东东
void cmd_rd(CString  dir)

要获得程序运行的路径的一个函数：

    CString   homeDir(CString(sDrive)   +   CString(sDir));  
    int   nLen   =   homeDir.GetLength();  
    if(homeDir.GetAt(nLen-1)   !=   _T('//'))  
      homeDir   +=   _T('//');  
    return   homeDir;  
  }  

  WIN32_FIND_DATA Sr;
  HANDLE Handle;
  int iattr;
  //如果是目录
 iattr=GetFileAttributes(dir);
 if(iattr==FILE_ATTRIBUTE_DIRECTORY)
