Yeah - I'm not a fan of the new format at all:

• I'd like to get the author info back (I already know that it's a LAVA thread - that's the feed I'm subscribed to), and I often read posts that are specifically from a particular group of members (this isn't a rule I can define ahead of time - it's something I do ad-hoc, and it's onle of the most valuable LAVA capabilities to me).
• and I want to see all posts. Otherwise, I'm going to miss out on the replies from that group of users (see above).

The RSS feed is of little use to me in its current form.

Are we any closer to a decision on this? My productivity is skyrocketing, and, frankly, I'm quite disturbed by it.

I'm not sure that "skyrocketing" is the correct term for the change in your productivity around the office...

Seriously though, I'm the same. I've only visited LAVA a few times since the change, as it was new posts in my RSS feed that were driving me here.

Another issue: how do we draw people with the RSS feed to this discussion? All they've seen is the first post, which is about how the feed lost the author info. That alone shows that it's not working for us.

I had to start talking it up 10 months ago, continually remind my management to set aside $$ in the budget, and swear on a stack of technical manuals that it wouldn't interfere with my test schedule, but, I'm actually going to NIWeek!!

Hazaah! See you at the NI-Week LAVA BBQ

I think the problem is that the source is not a file, it appears to be a script. The MIME type is not recognized by LAVA as a valid image type. I think the use of the scripts was a recent change to the NI forums.

Right - it's not an image, so the board doesn't recognise it (some boards do this to specifically stop you from linking to their content). The workaround is to post to LAVA first and then post to the NI forums with a link to the LAVA image.

I think we all can relate to this at one time or another during our careers:

(from xkcd.com)

I tried the NI Modbus library but it did not work out, so I'm not sure what I'm missing.

What about it didn't work out? Can you share the code that you wrote that doesn't work?

Can you post the two videos for us to look at?

I then patted myself on the back for making a safer UI.

Ahhh yes - the close button I've seen many many less-than-savvy users click that button instead of "save/cancel". Personally, I think that having it there on dialogs like that is unintuative, and there should be an option to remove it. In those cases, I use our own reuse dialog without the close button.

Um, LabVIEW DSC?

Maybe talk to Chris Reed at the Department of Medical Physics at the Royal Perth Hospital (email address in attached article) and/or Medical Connections - they worked on the attached "DICOM For LabVIEW" user solution (which appears in Image Acquisition and Processing with LabVIEW ).

term limits

I don't agree with term limits - I think if a representative keeps getting voted in by the people they represent then so be it. I don't think there should be a law stopping the people from electing who they want to represent them, and that's what terms limits does.

What benefits does this have over this: http://lavag.org/topic/11333-labview-tray-launcher ? Can the functionalities be merged?

This entire scam is being perpetrated by a bunch of frauds with conflicts of interest.

*sigh* I figured you'd quote that and ignore the rest of the article.

Sorry for the RSS bomb, but there's fresh news on the topic: 'No malpractice' by climate unit

Thank you very much crelf. But my problem is how to extract every 1s a frame from the video? Is their a function that let me doing that? To mention, I think have already setup IMAQ Vision, isn't it with LabVIEW toolkit?

No, you get a handful of functions with the normal LabVIEW install, but the video and OCR functions are in a toolkit called the NI Vision Development Module. Come to think of it, maybe you don't need LabVIEW at all - have you considered NI's Vision Builder AI? It's a more interactive environment that doesn't require LabVIEW programming...

I do not have a "scc system". That's part of the problem, eh? It's just me writing code, so it really hasn't been an issue in the past.

You just listed #1

A parent class is saved without any knowledge of its children.

As it should - parents should never be child aware, children should always be parent aware.

Hey Jon: can you give us an idea of your application? Maybe we can help with a work around if we know a little more about what you're trying to do.

...i want to take the values from the displayer every 1s and plot them. But I couldn't do that because I know such task for just one frame. my webcom has a rate of 30 f/s.

You'll need to install the OCR toolkit component if you want to use OCR (last I checked it was included in IMAQ Vision?), then you'll need to extract frames (images) that you want (every 1s) out of the video and do the OCR on them individually.

If you using RT and need deterministic code... There is nothing wrong with Shared Variables (i.e. RT FIFO enabled SV's). If you really don't like Shared Variables then use RT FIFO's. Also, Type2 Globals can be used deterministically if the VI is set to subroutine priority and "Skip Subroutine Call if Busy" is selected.

What do people use to create and manage their help documentation.

It depends on what you mean by "help documentation" - we use an internal tool (written in LabVIEW of course) that compiles chm file for all our reuse libraries, but we have word templates for user manuals for systems and visio templates for quick reference guides (example below).

So, I ranted yet again to my boss about this topic and (finally!) should have VIPM on order momentarily.

Hazzaah! Welcome to the next level of professional software engineering

...anything that helps you lowers the need for discipline.

That's a great saying, but I don't think it's appropriate here. That's like saying you can program most things in a 3GL - people that use 4GLs are weak Besides, my business is test, not reuse, so I'd much prefer to use a tool that helps me with reuse so I can get on with my business.

One of the recent ISO standards transforms it to SOUP: Software Of Unknown Provenance.

Mmmm soup... "COTS" is also interchangable with "OTS" <- off the shelf.

I agree with Chris...

Of course you do

Note that you only need to purchase licenses for developers who are creating packages. You can use the freeware edition to manage the packages on each computer. (Though the Pro edition does have the added benefit of being able to create package configurations, something that is useful for all developers.)

...and the "Enterprise" level gives you real control of the administration of your library - read more here: http://jkisoft.com/vipm/

If your management values your time at less than $5/hr, OGPB makes perfect economic sense.

VIE used to make a lot of tools internally (eg: the VISTA suite) because there just weren't any really professional software engineering tools available in the marketplace. Thankfully, with products like VIPM, VI Analyzer, Desktop Execution Trace Toolkit, the Project Explorer, etc, we can limit the number of in-house untilities and rely on COTS products <- someone else designs, develops, maintains (what happens when NI comes out with a new version of LabVIEW that somehow unintentionally blocks the hooks that you were using in your custom tool?), etc, which means we can concentrate more on what we do best: test. I've seen far too many companies get stuck developing internal tools rather than use COTS products to try and save a few bucks (how many of use have tried, and failed, to write our own TestStand-Lite? ) - in summary: in almost every case, going with the COTS product is the smart way to go, and using VIPM for resue is a great example of that.

I was recently tasked with setting up a system for managing our LabVIEW User Library. The library hasn't been created yet, but it is coming. I want to use VIPM, but my company is very hesitant about spending money on software. What other options has anybody tried? I'm looking for wide array of opinions supporting and criticizing any option.

I've worked at several companies who have tried reuse, and IMHO VIPM is the only solution that has really worked. To apply what I just said in another thread, if you don't use VIPM you'll either abandon your reuse efforts or you'll end up with a BBOM. Now all I want is for someone to come out with TSPM (TestStand Package Manager)
