提问之前，我有去搜过代码。
我自己写的如下：
#include "stdafx.h"
#include <windows.h>
#include <string>
#include <ctime>
/*
int settime(LPSTR file)
{
//LPSTR file = "xm.aspx";
FILETIME Filetime;
SYSTEMTIME systemtime;
systemtime.wDay = 1;
systemtime.wYear = 2000;
systemtime.wMonth = 1;
systemtime.wDayOfWeek = 1;
systemtime.wSecond = 1;
systemtime.wMilliseconds = 1;
systemtime.wHour = 1;
systemtime.wMinute = 1;
SystemTimeToFileTime(&systemtime,&Filetime);
//hfile = CreateFileA("1.txt",GENERIC_WRITE,0 , NULL,OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);
//if (hfile != INVALID_HANDLE_VALUE)
//{
SetFileTime(file,&Filetime,&Filetime,&Filetime);
// }
//CloseHandle(hfile);
return 0;
}
int main(int argc,char* argv[])
{
settime(argv[1]);
return 0;
}
运行完程序以后，目标文件时间并没有改变。
还请各位前辈们指出是那儿的错误。
直接这样设置时间是不可以的吗？
今天又看了下，此处错误原因是SetFileTime首个参数使用错误，句柄(hFile)，不是文件名(fname)。稍微改了下，你看看。
#include "stdafx.h" #include <windows.h> #include <string> #include <ctime> int settime(LPCSTR filename) { SYSTEMTIME systime; FILETIME ft, ftUTC; HANDLE hFile; systime.wYear = 2000; systime.wMonth = 1; systime.wDay = 1; systime.wDayOfWeek = 1; systime.wSecond = 1; systime.wHour = 1; systime.wMinute = 1; systime.wMilliseconds = 1; SystemTimeToFileTime(&systime,&ft); LocalFileTimeToFileTime(&ft, &ftUTC); hFile = CreateFileA(filename,GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ| FILE_SHARE_WRITE , NULL,OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL); if (hFile != INVALID_HANDLE_VALUE) { SetFileTime(hFile,(LPFILETIME) NULL, (LPFILETIME) NULL,&ftUTC); } CloseHandle(hFile); return 0; } int main(int argc,char* argv[]) { settime("gogooggoo.txt"); return 0; }
