Cloud Expo 2011 New York $800 Savings here! A number of verticals, particularly Financial Services, are moving towards a zero latency environment, where the reduction of time between decision and action is critical.

(I say ability because you still need to make your method interfaces Common Type System compliant.) Second, your code maintenance activities w... (more)

DataWindow Magic: Master_Detail Object

One of the most useful custom objects that I've ever written is my master_detail object. It holds a prominent place in my toolkit. This article will take you through the steps of how to write one and in the process de-mystify the object. First we want something that looks like Figure 1.
