Sophisticated DateTime “Formula Fields” with Apex and Field-Level Security

May 17, 2010 by David Schach 3 Comments

What do you do when you want to calculate a formula-like field but a regular formula won't work? Salesforce CRM's formulas handle dates very well. If you want to enter a date value and have formula fields display, for instance, mydate__c + 21 days, that's simple. Just use mydate__c + 21. Side note: If you […]

Overload Apex Class to be Controller AND Extension

July 24, 2009 by David Schach 2 Comments

Coding the new premium version of Mass Update Contacts (details to come), I replaced the two parts of the page with Apex Components. This will allow the app to support custom address fields and international address formats. I didn't want to write one ControllerExtension for the main page, a CustomController for the view section component, and another CustomController for the pageblocktable component. So here is the overloaded class constructor. Note that this works because an extension passes the StandardController to the constructor, and a CustomController passes nothing:

Email Inbox Version 2

July 15, 2009 by David Schach 1 Comment

Well, it took about ten minutes from the release of Email Inbox Version 1 for people to request additional features, screenshots, etc. Version 2 includes some neat icons, and this post has the multiple-times-requested screenshots we promised. First, a teaser screenshot. (There's a better one below the code.) Here's the updated Visualforce code: The Apex […]

Visualforce Email Inbox

July 14, 2009 by David Schach 4 Comments

Sonny Cloward, SysAd at Rainforest Alliance, approached us about writing a Visualforce page to display all incoming emails for a given Case Queue. This led to quite a few interesting discoveries. Here's how we handled the project:

Pulling Code Out of Triggers

May 18, 2009 by David Schach 6 Comments

To date, triggers have only been accessible on each object's setup page, leading to a lot of hunting for code within the Salesforce CRM application. Even in Eclipse, switching between the Class and Trigger folders for a given project can be a pain. These pains can partially be alleviated by keeping all Apex code in one place--as Apex Classes.

Hacking a Case Comment Trigger

April 1, 2009 by David Schach 8 Comments

There has been some chatter about asking the salesforce.com team to include the CaseComment object in the “triggerable” list. After conferring with JP Seabury (ForceMonkey), we designed a Rube Goldberg-esque solution to the problem.

Project: Lookup to Picklist

November 11, 2008 by David Schach Leave a Comment

In the first installment of post-Dreamforce projects, I present a mechanism to present the user with all available Lookup options in a picklist. This should simplify some Visualforce pages. (Credit to the Developers Guide from the new post-Dreamforce Library.) The key to the code is the ability to customize the SOQL statement to focus as […]
