//Declare a generic GPS connection variable GpsConnection GpsConn = null; //Use FileGPSConnection if you are reading GPS data from a file GpsConn = fileGpsConnection1; //Uncomment to Use SerialGPSConnection if you are reading GPS data from a device // GpsConn = serialPortGpsConnection1; //Use generic GPSConn variable for either type of connection Debug.WriteLine= GPSConn.Latitude.ToString(); Debug.WriteLine= GPSConn.Longitude.ToString(); Debug.WriteLine= GPSConn.Altitude.ToString(); Debug.WriteLine= GPSConn.FixStatus.ToString();

//Declare a generic GPS connection variable 
GpsConnection    GpsConn = null; 
 
//Use FileGPSConnection if you are reading GPS data from a file 
GpsConn = fileGpsConnection1; 
//Uncomment to Use SerialGPSConnection if you are reading GPS data from a device 
// GpsConn = serialPortGpsConnection1; 
//Use generic GPSConn variable for either type of connection 
Debug.WriteLine= GPSConn.Latitude.ToString(); 
Debug.WriteLine= GPSConn.Longitude.ToString(); 
Debug.WriteLine= GPSConn.Altitude.ToString(); 
Debug.WriteLine= GPSConn.FixStatus.ToString();

Remarks

This abstract class serves as the base for the SerialPort and FileGps connection classes. These connection classes are exposed as toolbox components. This class is useful when building your application to work with both live ( SerialPortConnection) or stored (FileGPSConnection) GPS information, since the code to display and use the GPS data is the same for both types. See the BasicGPS sample for code that uses both GPS sources.
