QUOTE (BrokenArrow @ Sep 18 2008, 04:02 PM) I have not been out of the "Funny 3-D vi's.... Objects! I've never used OOP in LV. " frame of mind that long, so lets see if I can help. You can think of LVOOP as a way of managing type-def'd clusters and a set of VI's that go with them all wrapped in a single llb. The "class" is the cluster. The member VIs are the VIs in the llb that are allowed to use Bundle by name and Unbundle by name on that cluster. So a translation to non-LVOOP speek is "Document the cluster and the VIs that use it." I will now step back and let the more LVOOPish out there correct me. Ben

I try to use the new functionality of flattening classes to XML but I got an error when I try to Unflatten a class containing another class within it attribute. Is it a bug or a misunderstood? See attach project. Download File:post-6703-1221752759.zip

QUOTE (rkanders @ Sep 17 2008, 06:01 AM) No the only downside I have heard of is that the .svn files are masscompiled (if you place user.lib inside svn, my advice don't do that). Or that the VI analyzer toolkit tests these VIs as well. You can set SVN to name the folders _svn which are ignored by LabVIEW. Ton

QUOTE (shoneill @ Sep 16 2008, 09:44 AM) Yup! Did it just last week. After restoring class data from file I was failing to clear the array of queues (contained in the class data) that had been used when the file was saved. It took me some digging before I figured out why posting to (now invalid) queues was not working after restoring from file. Ben

QUOTE (torekp @ Sep 16 2008, 07:40 AM) Code snippets usually read all terminals and nodes that are not delayed by data dependancies, so is there a possiblility that the local for "State" is reading a value of "stop" before its is set to another value? Ben

QUOTE (Antoine Châlons @ Sep 16 2008, 05:31 AM) I agree the code LOOKS wrong but since that code never execustes (false constant driven state) it can't (?) produce wrong results. Imagine trying to write a "tester" that finds an error in non-executing code. Ben

It includes example of about 95% of the most commonly used 3d graph functionality including multiple plots of varying styles. Have fun, Ben

QUOTE (george seifert @ Sep 15 2008, 01:55 PM) In the workaround.zip you have an example and a NIReport.llb folder, copy this NIReport.llb folder to <labview 8.6>\vi.lib\Utility. You have already NIReport.llb folder in the <labview 8.6>\vi.lib\Utility that contain the complet tookit. The workaround VI will replace all instance of "Get Report Type.vi" and with this version you will be able to access Word._document activeX Dany

QUOTE (george seifert @ Sep 15 2008, 12:18 PM) Hi George, The exemple VI will work if you copy the "NIReport.llb" folder in <labview 8.6>\vi.lib\Utility, this will replace all implementation of the "Get Report Type.vi" to be able to access the Word._Document activeX. There is an exemple of the implementation of the Get Tables Count. http://lavag.org/old_files/post-223-1221499285.zip'>Download File:post-223-1221499285.zip I hope this will help Dany

QUOTE (DidikChandra @ Sep 13 2008, 06:59 PM) You can shutdown Windows from LabVIEW using the system command 'shutdown'. In LabVIEW make a System Exec call 'shutdown -s -t 1'

QUOTE (crelf @ Sep 12 2008, 10:49 AM) How do you define and document your custom style? i.e. what thought process do you use to decide how to place and organize your LV diagram? And how do you tell a computer to do the same thing?

QUOTE (brianafischer @ Sep 11 2008, 11:50 AM) My personal feeling is that we should encourage all FIRST users to post questions on the FIRST community forum which will include all of the training materials, videos, manuals etc. specific to the cRIO toolkit for FRC. http://ni.com/first Scattering questions and answers among multiple forums will provide less benefit for reuse of previously answered questions.

QUOTE (Aristos Queue @ Sep 11 2008, 12:54 AM) Just judging by the images posted one idea would involve the Diagram Clean-up checking with the VIA to see how it did. One of those cleaned-up daigrams had a wire running under a string constant and would have failed that VIA test. Ben

Thank you Doug Dany

QUOTE ... I'm really pleased too

You should have a look at the examples (Hardware IO\DAQmx\Multifunction) A similar question is found here Ton

I was measuring analog and digital pulses for same event.Also we are acquiring analog and digital with different sampling ratesInitially both the acquisitions happening at same time and running at same rate,but after some time,digital acquisition going slow and values I was getting are deviated from analog in milliseconds are using M Series PXI 6254 Card,How can i make both the acquisitions to happen at same rate throughout the test. Regards, Naresh.N

Would it help to tag such a message as 'spam' or 'reported' after reporting? I have been doing so to let others know that the moderators are aware of the issue. Ton

Hi Dan, If I look at your program, here's what I would do (in text). Use the AI-clock as the clock of your counter. You don't need a start trigger for the AI task, via the AI-clock both tasks are synched. First start the counter task, second start your AI task (in the way you want) because both tasks use the same clock and the counter task is started first this enforces synchronized start. Ton

QUOTE (ExpoEra @ Sep 10 2008, 03:22 PM) It turns out the IO references are somewhat specific to the type of IO device. My original VI was created for cRIO IO. I updated the example for R series and have attached the new VIs and project.
