using information provided by a website on my windows application..

[paeez]

Hello,
I am writing a program in c# that should convert postcodes to the corresponding coordinates.
I assume there should be a sort of database,maybe gps coordinates data base, but i do not know how to access them. On the other hand i see that there are some websites that when you enter the postcode in the related text box, it will give u the associated coordinates. is there anyway that i make sort of query from my application to those websites,(sth like this: when a user enters a postcode in my windows application, the postcode field in that website be filled n gives me the coordinate), or any other suggestion to convert postcode to coordinates?

Many thanks,

I've used a similar API with Netflix but I haven't used the Google one in particular. Those links should get you started and give you some other search terms to try.

It was in the second link I gave you: http://code.google.com/apis/maps/documentation/geocoding/#ReverseGeocoding . There's a lot of power in these APIs but there's a steep curve in the beginning.
