  1. I've built (and re-built) a medium-sized application over the past months, learning more about LabVIEW in the process. The design is simplistic and reaching its limits by now, so I've been re-thinking the design lately. I'm looking for feedback on my design choices before I start implementing... all criticism and tips are welcome! The goal: flexible software for an ever-changing university laboratory environment, to be used and extended by students/staff with limited LabVIEW skills. Decisions: Avoid LVOOP unless clearly called for OOP has it's benefits but it makes code more complic
  2. I've recently built a medium-sized application that controls a bunch of devices in a university laboratory. From the start, I've been focussed on writing a modular, extensible program, as people tend to add or remove equipment and write new measurement routines accordingly. In my architecture, each device is represented by an Action Engine (i.e. Keithley Controller.vi). The UI is comprised of subpanels that contain a simple UI for a single device (i.e. Keithley Panel.vi). Due to the nature of AE's, any vi can send commands to any device; data changes are communicated to the panel through U
  3. I have some projects on the horizon that have to be more reliable than anything I have done in the past. And this new requirement has me thinking about how I deal with errors in LabVIEW more and more. Simultaneously I have been looking into the Actor Framework. The sample project in LabVIEW 2012 for the Evaporative Cooler does a great job of showing how many of the pieces of a full application fit together. However, as I have studied the example, I have noticed that in many places error handling has simply been ignored. An example of this is in the water level control... specifically, I take
