Given a specified starting long and lat point, how can I determine a long & lat value of a point that is 100 km away at a 45 degree angle from the starting point?

There's some great VB code (in an Excel file download (http://williams.best.vwh.net/ftp/avsig/avform.xls)) at the Aviation Formulary - http://williams.best.vwh.net/avform.htm
It is a combination of VBA code and Excel formulas but it is nicely organized, it's easy to work out.
