C++判断Office版本——转载

自：http://blog.csdn.net/lpc_china/article/details/18359145

主要原理：查询windows注册表microsoft office软件项的值来判断版本。

主要源码：

头文件：

 #pragma once
 #include <Windows.h>
 #include <tchar.h>

 class CJudgeOfficeVersion
 {
 public:
     CJudgeOfficeVersion();
     ~CJudgeOfficeVersion();

 public:
     BOOL JudgeVersion(OUT LPTSTR _lpVersion, IN DWORD _dwVersionBufferLen);
 };

源码：

 #include "JudgeOfficeVersion.h"
 #include <strsafe.h>

  * 函数功能：构造函数
  * 函数参数：无
  * 函数返回：无
