Thanks for the feedback, I think I'm going a couple of them.
Any other feedback?

Hi all,
I'm about to pick a Subversion client for MacOS X to use with LabVIEW, I read a couple of reviews (mostly from here on stackoverflow) but before choosing I'd like to have some feedback from LabVIEW users.
Anyone can recommend one?
Thanks in advance.

Hi Antoine,
You MUST have VIPM 2010. VIPM 2010 can now install packages anywhere on disk but it comes at the expense that packages built with 2010 and not readable with earlier versions. Once you move your package to 2010, can't go back.
The good news is that anybody can now build unlimited VIs in their packages with the community edition. Some goodies are reserved for Pro edition, but it's gonna open up to a lot of people.
Sorry, I guess I should have written this in the readme. (DONE)
I was suspecting this. I am about to upgrade VIPM, so that's fine.

I couldn't agree more.
My work experience with LabVIEW is half of yours but I felt the same after miserably failing my CLD-R.
One thing that killed is that the questions are really focused on the latest version (I'm still on LV 8.6.1).
(not so) Random thought :
Feedback node are probably a cool new feature that everyone should learn to use but shift registers still do the job quite well - and personally their graphical representation is clearer to me.
4 questions about feedback node, this is silly.

Thanks again!
Glad it helps!
Never mind - got it. I had to set the port number within the project file (A).
Yes, all the VIServer parameters need to be carefully set, that's what took me the longest to figure out.
Also as sachsm pointed out this is sort of an "old" way, I used it from LV 6.1 to LV 8.6 (and it might even work with older versions) but with newer versions you certainly have new ways.

Hi All,
I have an application which I've written to control a measurement system, the main app is based on a kind of queue driven state machine. This application is typically built into an exe before use and then run from that. I now want to write a second application that can programmatically fire off some of the operations (states) within the first app. So, my question is, is it possible to do this using standard queues?
Simply put, I have a Queue (sink) in App 1, and I want to write things into that queue from App 2. (note, this is not VI 1 to VI 2, this is separate apps...).
Thanks in advance for any help!

Yes, you can do that.
I posted an example a while ago, it was in LV 8.20 if I remember well.
See here, and this thread can be interesting too.
The example was with FGVs I believe, I also have one with Queues somewhere... (maybe).
hope this helps

Hello there,
I'm writing an app where I have a tab control on the front panel. When the vi is run the window is maximised.
I don't know what the size of the monitor will be so I'd like to be able to align the tab control relative to the page (as you would on a web browser for example) such that when the page is maximised it stays centrally positioned.
Is there an easy/built in way of doing this does anyone know please?
Thanks very much,
Martin
Hi,
This little snippet should help you.

I am very curious that i can't debug the below Labview 8.6 built-in examples:
TCP Communicator - Active.vi
TCP Communicator - Passive.vi
Anybody know how to resolve this?
very appreciate your help!!!
Open the VI properties (by hitting CTRL + i) go to the "Execution" section and tick the option "Allow debugging"

Congratulations to Darren who won the NI Week 2010 coding challenge!
With a very impressive display of Scripting (and a little 2010 knowledge) in the final round.
Mark's Darren Defeater mouse was of no use...
Maybe the challenger could have thrown it at Darren to distract him???
pictures or video anyone?

Hi Lavas,
i have a fundamental question:rolleyes: whenever i had some problems regarding to 3D picture i used OpenGl basics,I want to make sure if it is valid to refer to OpenGl as the basis of LabView?!
Use google, restricted to NI website, to find a lot of information on that subject.

One side question :
Why can't you use IMAQ & Vision Development Module? It would really make your life easier... :-o
-
The problem is that I don't want to use IMAQ and Vision. I don't have access to them, so I just want to use the default functions of Labview. Any help here, would be greatly appreciated. I am sumbled upon this problem, cuz I don't know how should I do this ...
Ufff, it's like saying : "I want to go from Paris to New York, but I don't want to take an air plane", it's technically possible but you're not really chosing the easiest way.
Basically you have to know the format of your image, read the binary data and convert it to an 2D array of pixel (that will be your image), and then you have to redevelop the equivalent of the IMAQ analysis functions. Good luck!
Another question would be on the slow speed image loading in labview. For an image of 2000x2000 pixels, per se, it takes some time to load it. Is it normal?
This is not "normal", can you show the code you use to load your image?
By the way, what is the format of your image and how do you acquire the image?

Just curious what tools people have found useful for Designing State Diagrams.
Remember the NI State Diagram Toolkit? I wonder if that will ever make a comeback.
Yes, it had a strange life cycle. Not sure I miss it though.
I found this free online tool which is pretty neat:
Looks nice. I use OmniGraffle, it's pretty cool (mac only though).

That's good to hear guys. Search is the biggest sore spot here and it's nice to see some improvement. However, there is still a 3 character limit on the search terms which I'm working hard to resolve. It appears this is a Mysql issue and not related to IP.Board but still is annoying and I'm trying to resolve it if possible.
Hmmm.. Well.. not so fast!
LAVA search seems to work much better than before, but it's still far from being fine.
If you go to the LAVA 1.0 section and do a search with "DLL" you get no result. Well it appears that 2 threads (see below) in the first page of the LAVA 1.0 section avec "DLL" both in their title and inside the thread as well and not just one occurrence.
And same for "PID" and... oh well, just any word in fact.

Hi guys,
Lets say i have a picture with symbol at the middle of the picture.
Symbol is filled with red color while background are in black color. (pls refer to pic)
Now that i want to measure the color within symbol , how do i define the AOI?
** i only want to include symbol area
Is there any way to do it in VBAI?
Thanks in advance for u guys opinion.
Hello,
I don't think you can define your "free shape" AOI, it has to be rectangular or circular or any geometrical shaped available in the palette.
That said, if colour is homogeneous on the aera you can define a rectangular AOI that is smaller than the symbol, so you only have one colour in your AOI. Would that be ok?

For those who use scripting, you might want to support these 2 ideas :

maybe there's hope for much more features soon :-o

I had imagined it to be the same and i did use color plane extraction.
The problem still persisted. I am extracting images frm vision acquisition express vi ( continuous acquisition from a folder)
It works for the first image just fime and from the second image on, it shows this error
Ok...
Can you post your code or a screen shot of it?
-
What version of VDM (Vision Development Module) do you have? I *think* the latest version includes an IMAQ Find Edge that works on most type of image.
Your image is probably be RGB, the IMAQ Find Edge used to only work on grayscale images.
If you read a JPG file containing a grayscale image it comes into LabVIEW as a grayscale image, you can use the "IMAQ ExtractColorPane" to obtain it as a grayscale image.

we're more of a real-sport country.
Yep, boys play football, girls dance and men play rugby.
-
Relatively to what we had before the improvement is huge. In the absolut, the search stopped being crap and it now works.
That's indeed a great news
-
Another neat feature is there is now an iPhone App that has been released to read and participate on the forums. However it only works with the newest forum version which we will be installing on Saturday.
that is great!

Hello everybody,
I am trying to make a GUI where all user custumizations to a number of graph charts etc. can be saved (line styles, axes etc.), but fetching every single property through its own property node will not be very pretty although it will work. Can I somehow fetch the entire set of properties for a graph chart instead of picking each property individually?
Best Regards
Jes Vestervang
I don't think you can, but somehow I hope you can.
I think someone had a try before you though, have a look it's interesting : Property Saver on NI Community.

We're still using 8.6 and we're now looking to upgrade.
Personally I really don't mind having a few crashes a day but ONLY if when I get one I have a cool "crash report" feature that lets me send a few words to the editor and then create a cool blog like this one http://log.maniacalrage.net/tagged/cscr
