C++判斷Office版本

頭文件如下：

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

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

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

實現文件如下：

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

#include "JudgeOfficeVersion.h"

		return bStatus;
	}

	bStatus = pJudgeOfficeVersion->JudgeVersion(szVersion, 500);
	if (!bStatus) {
		delete pJudgeOfficeVersion;
		pJudgeOfficeVersion = NULL;
		return bStatus;
	}

	if (pJudgeOfficeVersion) {
		delete pJudgeOfficeVersion;
		pJudgeOfficeVersion = NULL;
	}

	_tprintf(szVersion);
	system("pause");

	return bStatus;
