The Sample Code is Giving Strange Errors or is Crashing!

Many environments will not allow you to connect out on port 80, or will clip out XML data from these requests/responses. The easiest way to check for this is to open a browser on the machine running the sample code. In your browser, navigate to:

AVI - Service Reference

Then try to run one of the operations with your trial key. If you get a browser error, or get no data back, then the sample code isn't able to connect either. Contact your systems administrator to resolve why you are not able to connect to Service Objects.

Although it will only display this information for US addresses. This will be displayed in the "InformationComponents" array returned from the service.

What are the possible errors that AVI will return if an address is invalid?

I need to know exactly how long each of the output fields could be.  What is your standard field length?

As a general rule, you won't get a field longer than 80 characters.
