Is it possible to convert a String from DecimalLatitude/DecimalLongitude to Latitude/Longitude? Because, i need the Lat/Lon-String to greate a NMEA-Protocoll when i have no longer GPS-Data. So I can't use GPS.Latitude etc.
Erel has written and posted an application called GPS4PPC. It's in the Open Source section, and contains two routines (LatLonFromString and StringFromLatLon). If this isn't what you are looking for, it may give you something to work from.
