封装类之FileVersion（获取文件属性）

应用此类可以获取应用程序的程序名，产品名称，公司名称，版本号，版权等信息
1XX.h文件

class CFileVersion  {   // Construction  public:       CFileVersion();  // Operations     public:       BOOL    Open(LPCTSTR lpszModuleName);      void    Close();      CString QueryValue(LPCTSTR lpszValueName, DWORD dwLangCharset = 0);      CString GetFileDescription()  {return QueryValue(_T("FileDescription")); };      CString GetFileVersion()      {return QueryValue(_T("FileVersion"));     };      CString GetInternalName()     {return QueryValue(_T("InternalName"));    };      CString GetCompanyName()      {return QueryValue(_T("CompanyName"));     };       CString GetLegalCopyright()   {return QueryValue(_T("LegalCopyright"));  };      CString GetOriginalFilename() {return QueryValue(_T("OriginalFilename"));};      CString GetProductName()      {return QueryValue(_T("ProductName"));     };      CString GetProductVersion()   {return QueryValue(_T("ProductVersion"));  };      BOOL    GetFixedInfo(VS_FIXEDFILEINFO& vsffi);      CString GetFixedFileVersion();      CString GetFixedProductVersion();      // Attributes  protected:      LPBYTE  m_lpVersionData;       DWORD   m_dwLangCharset;       // Implementation  public:      ~CFileVersion();   };

3在使用的过程中实例化一个对象，调用相关的函数即可

在这里可以查到相关的文件属性信息，也可以在里面修改文件信息
