Hi,
i have a class project to write VB code to generate a point diplay of data coming into a GIS (Geographical Information System) called GEoMedia (this is similar to ESRI's ArcView GIS) running on a lap-top, from a handheld GPS receiver (through the COM port) in real time. Does anyone have any sample code that could help me with this task?

The general idea is that there are three tasks here:
1. Use an object that interacts with the COM port of the lap-top to receive the GPS data coming in from a handheld receiver.
2. extract the coordinate data from the NMEA-standard raw GPS data received throught he COM port.
3. display the data in GeoMedia (GIS) in real time as coordinate point data in the map view window.

In effect, thius project is about writing a sort of extension to customize the GIS to meet the objective of visualizing GPS data in real time. Any ideas!? :o(
