This is a cool little example of calling a REST web service with Apex. You enter your address and the Apex code fetches the geo coordinates from Yahoo! Maps. The service returns the data as XML. If you want to run this demo in your own org, you will need to do the following: Add [...]

Cross-posted at the Appirio Tech Blog. During Dreamforce 09 Kyle Roche and I participated in the Developer Hackathon.

November 25th, 2009, 5 Comments
Here’s a small Apex Trigger that demonstrates how to programmatically create sharing rules for objects with a private sharing model. It came in handy on a project about a year ago so I thought I’d post it. So the scenario is that the object has a private sharing model (Contacts in this case) so that [...]
Can't Get On The Apex Scheduler Pilot? Here's a Short Term Solution.
November 24th, 2009, 5 Comments
In Winter ’10, Salesforce.com released the Apex Scheduler. This feature allows you to schedule Apex classes to run at specific times.

Using Saleforce DML statements or DML database methods?
November 2nd, 2009, 6 Comments
Salesforce allows you to perform database transactions (insert, update, delete, etc.) using either DML statments or DML database methods. While they perfrom roughly the same functionality (with a few exceptions), DML database methods provide a little more granular control when bulk processing exceptions occur. The Salesforce documentation is good and extremely detailed but these two [...]
Book Review – Development with the Force.com Platform
October 26th, 2009, 1 Comment
I spent a good part of the weekend going over the newly released book, Development with the Force.com Platform by Jason Ouellette from Appirio. The book covers a surprisingly large number of topics in under 400 pages and is a great reference for both Salesforce.com administrators and developers. In the effort of full disclosure, I must [...]

Cross-posted at the Appirio Technology Blog Governor limits are runtime limits enforced by the Force.com platform to ensure that your code doesn’t, among other things, hog memory resources, lock up the database with an excessive amount of calls or create infinite code loops. Working within governor limits requires you to sometimes become creative when writing [...]
