Special Topic:
ULO (User Listing with ORDA) – J Douglas Cryer

In this meeting, we talk to J Douglas Cryer (aka Dougie) of Telekinetix about a component (ULO) he has developed over the years to provide flexible and extensible user interface and functionality for his 4D development projects. In more recent versions of ULO, Dougie has leveraged the newly released ORDA language for 4D programming to maximize the simple and powerful features of his root component for client systems.

Get tour of what ULO does today… and also the exciting changes around the corner!
