VC检测Office版本
现在做的一个项目，里边用到了ActiveX控件，内嵌了Word，在安装Word的电脑运行是没问题的，但是在没有Word环境的电脑上就出问题，所以需要检测一下当前机器是否安装了Office，然后做出友好提示。在网上找了一个类（类的声明实现都在.h文件里，用的时候包含一下就行了），挺好用的，原理是搜索注册表，查看是否存在Office注册表文件，如果已安装，便获得当前Office版本的详细信息，如果没安装，返回 Not found. 这个类贴在下边了，后边还附了使用示例，兄弟们拿走不谢（借花献佛吧）。
class OfficeVersion
{
public:
enum eOfficeVersion
{
eOfficeVersion_Unknown, // error return value
eOfficeVersion_95,
eOfficeVersion_97,
eOfficeVersion_2000,
eOfficeVersion_XP, // XP = 2002 + marketing
eOfficeVersion_2003,
eOfficeVersion_2007,
eOfficeVersion_2010,
eOfficeVersion_2013,

const int numItems( sizeof(appsToCheck) / sizeof(appsToCheck[0]) );
for(int i=0; i使用示例：
OfficeVersion::eOfficeVersion eOffVer = OfficeVersion::GetApplicationVersion( OfficeVersion::eOfficeApp_Word )//OfficeVersion::eOfficeApp_Word 代表查询的是word版本， OfficeVersion::eOfficeApp_Excel, OfficeVersion::eOfficeApp_Outlook, OfficeVersion::eOfficeApp_Access, OfficeVersion::eOfficeApp_PowerPoint,分别对应的是各自版本（就不一一说了，含义大家都看得懂的)
CString strVersion = OfficeVersion::GetVersionAsString( eOffVer);//返回版本信息
