    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,
    keeper

    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;
    }

        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.
