I'm trying to select a address from the database and displaying them in the Visual Force page by using a add button.


Say if I add


1870 Fair Oaks West Sunnyvale 94086 CA address to my list, I can again add the same address to my list which is causing duplicate records, how do I prevent this duplicate record from being added again ?

Hi All


I would like to know where is the Error log stored in Salesforce. I have written Apex code which catch and throw exceptions.

I want to know where the exceptions log is maintained in SFDC.



Is there a way to detect in Apex if the system is a Sandbox or a Dev Edition?
