Labview anti-pattern: Action Engines
Mike Ashe replied to Daklu's topic in Application Design & Architecture
In the same boat. I've been reusing the same General Logging Library so long it is still in a *.llb and seems fossilized. My version is queue based with a handler that is started by calling the Startup method. Lets be clear that this is not OO based, or classes. The Methods VI is called with a "Logger Method" ENUM. I have a few extra "Methods" beyond those mentioned by others above, ENABLE / DISABLE - turns logging temporarily on/off OPEN / CLOSE - The background Manager is also a GUI showing the last 20 events, a new event alert flasher with Ack button. Open/Close methods make the GUI a -
Glad to hear that you got your project working (aren't bright eyed interns great?). Since there is not much motion control here on LAVA (so far) it would be great if you posted a short example of what you did to solve this. Every little technique explained adds up. Thanks!

Nice example Eugen, this could be worked into something suitable for the Code Repository, as well as Wiki. :thumbup:

LabVOOP Usage 1 Year Later
Mike Ashe replied to Aristos Queue's topic in Object-Oriented Programming
I haven't really gotten into it in the last year due to the non-target deployment issue. Hopefully that will change in the next year. I've been working on a modularized RT (mostly PXI) system the past year and I think it would really benefit from LVOOP if we could get it down on the RT PXIs. -
I can picture a figure skater, with special shoes, leaping and wiring and it looking real great from a gee-whiz standpoint, I'd love to see it. Not very practical for day to day.

I for one will continue to use QSM's in their various forms for a long time. I agree that they can get unwieldy, but I think that is more of a coding style and documentation issue than an architectural issue with QSM's. With a reusable template, a library of VIs to implement the QSM and the discipline to document properly along the way I haven't found them to be a problem. Just my $2 Mike

QUOTE(brianafischer @ Jul 2 2007, 10:26 AM) Are you looking primarily for a static display or one that updates programmatically at runtime? If you are looking for simple equations, single line and dynamic, you will find some examples shipping with LabVIEW. Use the Example Finder under the test menu.

All this discussion of the different disciplines reminds me of a study I once read about ... MIT once studied the differences in approach to problem solving by engineers, physicists and mathematicians, so they invited a sample group up to the lab and ran a simple experiment. The participants were to be admited to the experiment chamber one at a time and told to observe and take whatever action they deemed appropriate. The Engineer was admitted first and upon entering the room noted a fire blazing in the middle of the carpeted floor, with flames shooting almost to the ceiling. There was a buc

QUOTE(Jim Kring @ Jun 28 2007, 10:37 PM) I'll reply to you as I did to my first year EE professor, "with all due respect Sir, only electrons really flow, there is no such thing as 'hole flow' or positive current, protons do not flow, electrons do, and I'll put it down on your test if it will make you happy (and get me a good grade), but I don't have to buy into it, and I don't" That having been said, the video editor in me is thinking ...

Consider also the relativity of what is lifted in relation to what. If I stand on my head & hands (3 point) and then press up on a handstand (wish I could still do that easily ) then I am "lifting" the earth by the inverse ratio of it's mass to mine, just as surely as I am lifting myself. Today's bit of totally useless trivia ... Brought to you by the Makers of ...

QUOTE(jpdrolet @ Jun 27 2007, 07:19 PM) Break it, no Lay it aside voluntarily, yes Volition > Constriction As for measurement, sure. If a 3D cylinder projects itself through a 2D plane it shows up as an elipse, which in the domain of the plane (I couldn't resist) can be precisely defined and measured. It can come and go, (move), change shape, (morph) and disappear and reappear in a different portion of the plane and cause all kinds of arguments and discussion and disagreement as to it's nature among the inhabitants of flatland, yet the cylinder never changes it's 3D shape or nature

As I recall, if you use EMF (Enhanced Meta file) you not only get scalable graphics, but you get transparency as well.

Congrats Joe!
