[Tolga Balci]

How do I read/convert the Windows FILETIME struct into a TDateTime?

Try something like:

FILETIME ft;
SYSTEMTIME st;
FileTimeToSystemTime(&ft, &st);

TDateTime dt = TDateTime(st.wYear, st.wMonth, st.wDay)
+ TDateTime(st.wHour, st.wMinute, st.wSecond,
st.wMilliseconds);

// Note: FileTimetoSystemTime is a standard NT API function.

FileTimeToSystemTime(&ft, &st);

TDateTime dt = TDateTime(st.wYear, st.wMonth, st.wSecond)

+ TDateTime(st.wHour, st.wMinute, st.wSecond, st.wMilliseconds);

// Note: FileTimeToSystemTime is a standard Win32 API function.

PS: Is it only me or does everybody else think that it is odd ( more like stupit or
retarded ) for VCL's TDateTime to support direct conversion from and to the old Dos
filedate format but not to the Windows FILETIME.. format????

I think this is the best way to get a file date/time as reported by WinAPI functions
converted to a TDateTime:

TDateTime FileTimeToDateTime( FILETIME *FileTime )
{
FILETIME LocalFileTime;
SYSTEMTIME SystemTime;

FileTimeToLocalFileTime( FileTime, &LocalFileTime );
FileTimeToSystemTime( &LocalFileTime, &SystemTime );

return SystemTimeToDateTime( SystemTime );
}
