VS2022调试通过海康摄像头烟火识别SDK的实现

下面是我根据海康官方文档代码，放到VS 2022 版本中调试通过后的代码：

#include <stdio.h>
#include <iostream>
#include "Windows.h"
#include "HCNetSDK.h"

using namespace std;

//时间解析宏定义
#define GET_YEAR(_time_)      (((_time_)>>26) + 2000) 
#define GET_MONTH(_time_)     (((_time_)>>22) & 15)
#define GET_DAY(_time_)       (((_time_)>>17) & 31)
#define GET_HOUR(_time_)      (((_time_)>>12) & 31) 
#define GET_MINUTE(_time_)    (((_time_)>>6)  & 63)
#define GET_SECOND(_time_)    (((_time_)>>0)  & 63)
