Hello Rossko,
Your tips were very helpful to me thanks
I had only a limited time and by the time I had to set aside (sadly
some of your suggestions).
"It is slow, and if the geocoder Makes A Mistake"
As for the error on the discovery of the address I fix enabling the
operator can change the address in a way that is readable by the
geocoder.
"Yes, do not store your geocode addresses Every time the page is
viewed.
The page is loaded all the stores because I seek not avnedoli already
included in the database in the form: City, Province, State / Country,
address. depending on the store interogo to search the database
according to its city and state in order to further weed out the DB.
"Gecoding is asynchronous; your 1000ms delay is a kludge and is not
the correct way to use asynchronous services. "
is very interesting when I have more time to get their hands on this
program I try to improve it as you say.
Thanks:)
Eventually I succeeded, and the function does what it should do.
I'll put you below XD
