CreateFile GetFileTIme SetFileTime

Question

I\'m having trouble using GetFileTime and SetFileTime when it comes to directories. Specifically I think my problem is that I am new to the WinAPI and I don\'t think I\'m

Answer 1

Here is a code example on how to set a directory's date based on a DOS date timestamp.

int Directory_SetDosTime(char *Path, unsigned int DosDateTime)
{
    FILETIME LocalTime, FileTime;
    HANDLE Handle;
    SYSTEMTIME SystemTime;


    DosDateTimeToFileTime((DosDateTime >> 16), DosDateTime, &LocalTime);
    LocalFileTimeToFileTime(&LocalTime, &FileTime);
    FileTimeToSystemTime(&FileTime, &SystemTime);

    Handle = CreateFile(Path, GENERIC_WRITE, FILE_SHARE_WRITE,
                    NULL, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, NULL);

    if (Handle == INVALID_HANDLE_VALUE)
    {
        //Unable to open directory
        return FALSE;
    }

    if (SetFileTime(Handle, &FileTime, &FileTime, &FileTime) == 0)
    {
        //Unable to set directory time
        CloseHandle(Handle);
        return FALSE;
    }

    CloseHandle(Handle);
    return TRUE;
}

Answer 2

Answer #2: To use CreateFile to get a handle to a directory, you need to use the FILE_FLAG_BACKUP_SEMANTICS flag. Using your example:

h1 = CreateFile(itemA, GENERIC_READ, FILE_SHARE_WRITE, 0, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, 0);

I would guess this would work for Answer #4 as well, but I haven't tried it to confirm.
