Invoking Lead Assignment Rule From Apex Code
​
I am not having success. Can anyone help. I am an admin. Not a developer. New to APEX. I am running a app with an Apex Class Email Processor. Do I plug the code in the existing Apex Class Email Processor or create a new Apex Class? Do I use an existing or create a Visual Force page? Other? I tried adding to existing and the assignment rule is not working. I tried creating a new Apex Class, the code as is is not accepted. I also created a Visual Force page and the rule does not trigger. 

//Fetching the assignment rules on case
02AssignmentRule AR = new AssignmentRule();
03AR = [select id from AssignmentRule where SobjectType = 'Case' and Active = true limit 1];
04 
05//Creating the DMLOptions for "Assign using active assignment rules" checkbox
06Database.DMLOptions dmlOpts = new Database.DMLOptions();
07dmlOpts.assignmentRuleHeader.assignmentRuleId= AR.id;
08 
09Case newCase = new Case(Status = 'New') ;
10//Setting the DMLOption on Case instance
11newCase.setOptions(dmlOpts);
12insert newCase ;

In one of my Sandbox ORG's, I've my IP range added, and I am able to login to the website, but the Force.com IDE simply won't allow me in...keeps telling me that my credentials are wrong.

Any help will be much appreciated.

Thanks.
