I was prompted to write this post after hearing a LabVIEW presentation at a user group where the presenter made a throwaway comment “I don’t see the benefit of using bookmarks, I can find the code I’m looking for simply by a VIs filename” I was tempted to jump in and add my thoughts right … [Read more…]
I’ve been using LabVIEW for a long time. I started out with version 3.1 for Windows but then went on to use some flavours of LabVIEW 2 for the Macintosh. There have been some great additions since then including LabVIEW Classes, User events, network shared variab…….just kidding. Heck, even the colour box constant has moved … [Read more…]
A customer called me up the other day to tell me that the LabVIEW application I wrote for him several years ago needed to be updated for the latest Intel processors. “Oh really?” I asked. “What feature of these new processors am I not taking advantage off?” “No No, nothing like that, It’s just running … [Read more…]
At Delacor we often talk about programming style, and I like to refer to Fab’s style as “defensive programming”. The overwhelming theme in her code is focussed on robustness and avoiding, wherever possible, the opportunity for things to go wrong. Over the past few years this has resulted in several internal “tips & tricks” for … [Read more…]
This year has been an interesting year so far. We made it to the CLA Summit in Austin and the one in Germany. We couldn’t make it to the first CLA Summit in India, which is a shame, because until then I could say that I was the only non NI employee who had been … [Read more…]
This is a post I have been wanting to write for a long time, not to share some technical nuance or promote some new product, but because of the philosophical debate that I hope it promotes. It is something I have wondered about for several years, and my viewpoint on it has shifted several times. In … [Read more…]
For the past few months we have been working on an automated test project where several pieces of instrumentation (and the Unit Under Test) are handled by a DQMH module. These modules are launched by, and then run asynchronously to, a TestStand sequence. This is a great way to implement automated tests, as it results … [Read more…]
As we approach the end of the year, it is all too easy to get caught up in planning the events and goals for 2016. However, it’s worth taking the time to look back on the year just gone and reflect on the achievements and lessons learned. Events of 2015 As National Instruments Alliance partners … [Read more…]
A few months ago I published this blog post about User Events in LabVIEW. From the replies and questions that this sparked, it is clear that many people either use LabVIEW User Events as the primary message transport in their applications or are planning to do so in the future, and that the concept of … [Read more…]
If you are a regular visitor to this blog, you may have heard us mention the DQMH (Delacor Queued Message Handler) from time to time. The DQMH is a framework that we use with our customers, and it is available on the LabVIEW Tools Network. In this post I’m going to be looking at a particular … [Read more…]
