Finding locations by post code

[faizee36]

Hi all,
i am building and asp.net application using visual basic 2005. i am building this application for a primary care trust. in my application i want my user to find their nearest surgery just by typing their post code. but don't know how do i start.
i have seen this thing working on

http://www.nhs.uk/England/Hospitals/...tHospital.aspx

i know there is a function but don't exactly know how does it work? the function is
function ShowMap(postcode). Please keep in mind that i am new to web development so may ask stupid questions.
thanking in advance
Ali

Royal Mail hold the post code database which you would need and can buy from them (as it isn't free). You could then just use an SQL query to work it out.

Alternatively, you might be able to look into using Google Maps and it's API for a somewhat free (albeit a kind of hack) method. Here's a starting point if you choose to go down this route:
