title: Google Maps API v3 coordinates of map after move
body: <p>i am a VB.net programmer. not familiar with jscript.</p>
  
  <p>I am building a web app that will display points on a google map from a database. i save the latitude and longitude for each record and use those to load the points on the map.</p>
  
  <p>i have it working but i can't figure out how to update the points once the user moves the map. Is there a way to get the top-left latitude longitude and bottom-right latitude longitude of the map after the user moved or zoomed so i know which record to load from my database?</p>
