i am working on Google maps v3 (optimized)in Asp.net.

i wanted to design a Gps program using NMEA Serial port device
(which generates this sentence;
$GPGSA,M,3,05,25,12,29,10,02,,,,,,,2.6,1.5,2.1*34
$GPGSV,3,1,11,05,69,067,23,25,53,244,19,29,45,322,31,12,42,197,16*7C

which i wanted to integrate with my Google map api v3 in c# or vb.net project.
my problem is that i am really stuck at Gps Device integration within Asp.net code file.i am unable to understand How can i call the Google map v3 into my code file and How to open Serial comm port. and set my NMEA sentence with the google map v3..
any help will b appreciated.i am not much good in programming..doing my studies and this one as my Final project.
