分享C/C++ SetFileTime 修改文件时间时报错
// ConsoleApplication2.cpp : 定义控制台应用程序的入口点。
//
#include "stdafx.h"
#include <io.h>
#include <windows.h>
#include <direct.h>
int _tmain(int argc, _TCHAR* argv[])
{
HANDLE hFile = CreateFileA("D:\\log.txt",GENERIC_READ|GENERIC_WRITE,FILE_SHARE_READ|FILE_SHARE_WRITE,NULL,OPEN_EXISTING,0,NULL);
//获取文件时间
FILETIME createTime,accessTime,writeTime;
GetFileTime(hFile,&createTime,&accessTime,&writeTime);
//将文件时间转换为系统时间
SYSTEMTIME sysTime;
FileTimeToSystemTime(&writeTime,&sysTime);
//格式化字符串
char msg[256];
sprintf_s(msg,"%d-%d-%d-%d-%d-%d-%d-%d",
sysTime.wYear,sysTime.wMonth,sysTime.wDay,sysTime.wDayOfWeek,sysTime.wHour,sysTime.wMinute,sysTime.wSecond,sysTime.wMilliseconds);
//将字符串转换为系统时间
SYSTEMTIME newSysTime;
sscanf_s(msg,"%d-%d-%d-%d-%d-%d-%d-%d",
&newSysTime.wYear,&newSysTime.wMonth,&newSysTime.wDay,&newSysTime.wDayOfWeek,&newSysTime.wHour,&newSysTime.wMinute,&newSysTime.wSecond,&newSysTime.wMilliseconds);
//将系统时间转换为文件时间
FILETIME newWriteTime;
SystemTimeToFileTime(&newSysTime,&newWriteTime);
//设置文件的时间
SetFileTime(hFile,&newWriteTime,&newWriteTime,&newWriteTime);
CloseHandle(hFile);
return 0;
}
执行的时候会报错 请大神指点一下那个地方有问题

sscanf_s的时候你是将一个int数据写到了一个WORD类型的地址上了
