changing file date

Hello,

I want to change the creation, last modified and last viewed date of a file. Can somebody help me with that? I think it can be done with the windows api, but I have no idea how.

MFG,

SetFileTime

Simple example which creates file time.txt with very strange dates.
The SYSTEMTIME struct:

Code:

---

typedef struct _SYSTEMTIME {
    WORD wYear;
    WORD wMonth;
    WORD wDayOfWeek;
    WORD wDay;
    WORD wHour;
    WORD wMinute;
    WORD wSecond;
    WORD wMilliseconds;
} SYSTEMTIME;

---

And here's the code:

Code:

---

#include <windows.h>

int WINAPI WinMain(HINSTANCE hThisInstance, HINSTANCE hPrevInstance, LPSTR lpszArgument, int nFunsterStil){
    HANDLE hFile=CreateFile("time.txt",GENERIC_WRITE,0,NULL,OPEN_ALWAYS,0,NULL);
    FILETIME created,accessed,modified;
    SYSTEMTIME sys_created={1601,1,1,1,3,7,9,0},sys_accessed={1704,2,1,2,11,43,12,0},
        sys_modified={2962,1,1,8,19,42,40,0};
    SystemTimeToFileTime(&sys_created,&created);
    SystemTimeToFileTime(&sys_accessed,&accessed);
    SystemTimeToFileTime(&sys_modified,&modified);
    SetFileTime(hFile,&created,&accessed,&modified);
    CloseHandle(hFile);
    return 1;
}

Thanks, but where get this file time.txt saved and how does I change the date and time of an existing file. And can you tell me how to call this function int WINAPI WinMain(HINSTANCE hThisInstance, HINSTANCE hPrevInstance, LPSTR lpszArgument, int nFunsterStil). I don't know what parameters to give.

WinMain is like main for windows programs.
