Encryption & Decryption with Crypto

Platform security is important. Creating a composite application for the AppExchange, developing integrations with open authentication (OAuth) or simply integrating salesforce with an internal system/platform can make your security team nervous. However, the Salesforce Crypto class should put your security folks at ease. [...]

RecordType Utility Apex Class

I like to group Apex methods by the object to which they apply. I find that this supports troubleshooting of code and ultimately reduces the amount of code in a given Salesforce organization. For example, every Salesforce developer that works in an Enterprise level organization or higher will find that more often than not they need to know the record types for a given object. [...]

Pass Values to New Opportunity Using Apex

Last year I wrote a post describing how to pass values to a new opportunity using the URL. This post is simply an alternative to accomplish the same goal of auto-populating values to a new record except using Visualforce and an Apex Class controller. For the purposes of our demonstration we will make some general assumptions about the values we want to pass to the new record. To keep it simple we plan on populating the Name, Stage and Close Date of the new opportunity. We will also make the logic flexible enough so that if Salesforce happens to pass additional information we will be able to include those key value pairs as well. [...]

Locale Aware DateTime Component

I am working with a client that is deploying some existing Visualforce pages to international Users. The Visualforce includes some Date and DateTime values so I checked them to make sure they would render appropriately for people accessing the logic internationally. It turns out that the original Visualforce code uses the <apex:outputText> tag to drive formatting for much of the Date/DateTime values within the pages. Therefore, I am converting the occurrences of each <apex:outputText> tag to the Visualforce component I built for rendering. [...]

UNABLE_TO_LOCK_ROW Error Message

I was recently developing some Apex logic and encountered the UNABLE_TO_LOCK_ROW error while running my Apex unit tests for the new code. This UNABLE_TO_LOCK_ROW error message can happen when unit tests update the same record(s) at the same time or when unit tests try to create records with duplicate index field values. One way to avoid this UNABLE_TO_LOCK_ROW error is to simply turn off parallel test execution. This can be accomplished via Setup > Develop > Apex Test Execution. [...]

Edit Link Override Visualforce Page

I just built a Visualforce application that people can use to associate a number of "child" records to a single "parent" record. Let's say that the application uses the Account object as the standard controller and then we extend the logic so that we can find, manipulate and link many Contact records. The functionality of the application is not important for this post but how we access the application is important. [...]

Custom Error Handling in Visualforce

I am a big fan of developing Visualforce pages that are useful to humans. This means providing helpful feedback to the person interacting with the application in order to limit User frustration. In some circumstances this means providing clearer error messaging rather than simply outputting any system generated errors. [...]

Error Handling in Visualforce with <apex:pageMessages>

A big part of building Visualforce pages is making sure that the human has a good experience while interacting with the page(s) you've designed. This means that you need to have a good way of handling errors when and if they occur. In this post I will highlight one of the simplest ways to handle an error by utilizing the apex:pageMessages tag within your Visualforce page. [...]

Pass Values to New Opportunity Using URL

Pass values to a new Opportunity via a custom button using nothing but the URL. This can be useful if you want to default some values on the detail page when new records are being created. It can save your Users some time so they don't need to fill out every field. It will also allow you to provide some guidance for values you want provided when new records are created in your organization. [...]

Visualforce Page Rendered as PDF

A few years ago I started generating PDF invoices and receipts directly within Salesforce. Since invoices or receipts may have many rows of data and the data may span multiple pages, I decided to include a page counter in the margin of each rendered page. [...]
