my summer project

Over the summer i took part in a nuffield bursaries thing and I had to create a program . I decided that the project should be to do with something I liked and something that goes hand in hand with programming is gaming. So after some thought i decided to create a web application which takes a persons postcode and gamertag then uses googles API to plot the persons location and show their gamertag in a info window :).
Heres a few screenshots of it.



















































One thing about the google API is that it requires alot of hard-coding, so to make an application which automated the api was somewhat difficult. The google API uses geo coordinates to set the marker in the correct place. So for the application to automatically find the correct geo coordinates after a postcode was typed in required a database, Sadly a full uk database costs £2500 to buy from royal mail and then an aditional £1000 for it to be updated each year. I therfore had to find something more in my price range (£0) and after alot of hours of searching i found a database which has geo coordinates for the first section of a postcode so i used that. Its not perfect as its not as accurate as it could be but its ok for deonstration purposes. Also while im on the subject; if anyone would be generous enough to give me a full ostcode database it would be much appreciated.
