Why property nodes are not accept input?

Well, this one is driving me crazy.  I have a Subvi, which contains a string indicator and a drop-down list box, as well as a few buttons on the front panel.  My problem is that when I run the program (in LabVIEW, not an exe file) sometimes the window Question (the light) accepts the string and updates the property of Caption.Text, sometimes it doesn't.  At the same time, sometimes the answer box (combo box) accepts the Bay of cluster in it is StringsAndValues well, sometimes it doesn't.  They both either work, or they do not.  Never a problem with accepting Question window indicator string.

The block diagram:

Here is an example of the code powering the Subvi.

I don't get any kind of error message.

Sensors at the entrance of the property offending nodes indicate that the correct data are happened to them, it is just 'ignored '.  Once it starts to spoil, it usually continues to do.

It seems that the only way I can get to behave correctly should quit LabVIEW, and then restart LabVIEW and run the vi.  Then it will usually works a few times until it starts to work.

(Win 7, LabVIEW 9.0f3)

Thoughts?

What is the source of the wire that goes into your sub - VI Q & A mistake?  Is it possible that you have found errors on this thread?

If there is an error, these property nodes will not run.

  • Change the graph of mulit-field in front of Subvi - property node does not accept the cluster

    Hello

    I try to make a graph of multi-terrain waveform on the façade of a under VI.  I have created a command reference and fed in a cluster to sub - VI.  When I try to connect to a cluster of data for the façade, I get a broken wire:

    Can someone tell me what I am doing wrong?

    Thank you

    If you want the chart to accept a cluster in the Subvi, son first a cluster in the main VI in the table and then re-create the reference.

  • Why bitmp index are not suggested for DML operations

    Hi all

    Can someone make me understand why bitmap indexes are not suggested to use for DML operations. AFAIK, the reason being that it locks the table and another user won '; t be able to complete the transaction but why?

    user13389425 wrote:
    the reason is that I found is that it stores the rowid of beginning and the end rowid and the value of the spreadsheet store n number of entries of the inder, so any operation DML whole leaves lock themselves and cause the performance of the database. My next question I was not able to address, is that the index entries how do I store it on a single sheet. How calcualte the same.

    It is not the entire sheet that gets locked, just the specific index entry in the block sheet index, as well as the corresponding lines in the table referenced by the rowid ranges in the index entry.

    As an indication, the average number of index entries in a block of sheets is the num_rows/leaf_blocks in dba_indexes. As an example, the average number of rows in the table referenced by the index entry is (num_rows in dba_tables/num_rows in dba_indexes) * distinct_keys in dba_indexes.

    You can also configure a project basis including all titles.  When it's time to start a new project, open the template and change the name before starting to work.  In this way all the foundations are in place without having to implement the project with these basics every time.

  • LabVIEW 7.1 IVI - C Wrappers and VISA property node do not work together?

    Hello world

    I want to use the property node VISA with LabVIEW 7.1 Wrapper of two companies different well known instrument, Rodhe-Schwarz and Agilent Technologies.
    The two companies releasead their IVI - C for NI LabVIEW 7.1 drivers version NI Instrument Driver network and they are ready to be installed and used.

    I found a bug manifested that the LabVIEW 7.1 version that the bug is not present in whhen versions 8.0 LabVIEW or LabVIEW 8.6 than these IVI LabVIEW of LabVIEW 7.1 wrappers are used.

    Everyone could exeperience this bug if they have LabVIEW 7.1 installed and are trying to use the version of LabVIEW 7.1 of these wrappers which are published in NI Instrument Driver Network under the links below.

    Agilent ag81150ni IVI Driver for LabVIEW 7.1 install from here. Used in simulation that by definition simulate = 1

    http://sine.NI.com/apps/UTF8/niid_web_display.download_page?p_id_guid=55798957B1A633BDE0440003BA7CCD...

    Rodhe Schwarz rsngpt IVI Driver for LabVIEW 7.1 install from here. Used in simulation that by definition simulate = 1

    http://sine.NI.com/apps/UTF8/niid_web_display.download_page?p_id_guid=E3B19B3E91D6659CE034080020E748...

    After the installation of these two complete drivers close LabVIEW 7.1, if it was open, and then restart LabVIEW 7.1. You can see two new ready to be used as LabVIEW 7.1 IVI drivers in the LabVIEW Instrument Driver pallet wrappers in a LabVIEW 7.1 VI test.

    Open a new white VI and of the use of the Instrument Driver Palette two VI known, initialized with Options.vi and Close.vi adding them on the block diagram, connect all THMs. Accept all default settings except simulate parameter which must be defined as = 1 simulation.

    The two VI run OK mode of simulation without errors.

    Now select a property in the advanced Panel of VISA node and press this node between 'Initialize them with Options' and 'Close' VI and make all necessary in-out connections and error.

    Run these two simple screws of simulation

    1. When I run pilot Rodhe Schwarz IVI the property node going OK until the end. No error
    2. Whne I run Agilent IVI driver the property node is always out of the error Code 7.

    Question is why they behave different with regard to the property of node when it is used with the LabVIEW 7.1 envelopes? BTW, the failing VI of wrappers Agilent LabVIEW 7.1 works very well in labVIEW 8.0 and 8.6. That means that this problem is limited only the version of LabVIEW 7.1.

    I posted the same question on the set of LabVIEW and nobody chose their interest in there so I decided to post here. As this question is also linked to IVI, VISA drivers, it is possible the person of this group to get a clue about this annoying behavior.

    I've attached screenshots of the PNG files that show the difference of different behavior of VISA property between these two drivers node.

  • MCListbox property node does not during execution

    Hi I have problem with MCListbox property node. I wanted to fill the column with names and elements in the table.

    Initially, the program runs smoothly under development without error time.

    However when I she ran during execution of the table cannot be completed and produced by mistake. The error that says that "[get article] Config Registry.vi data: invalid object 0.

    I'm not sure what the error means that I need to find the bug in the moment of the execution because it works very well under development time. I found MCListbox property node errors after the names and elements are tempted to be filled in the table. I don't know why there are errors to the difference in time of development. See attachment below

    Thanks please advise

    Clement

    You read data from the configuration file? How do you get the path that it? You know that there is a difference (http://digital.ni.com/public.nsf/allkb/FD7DE8BC8FFC256C862565F4006BE363) between the path to the runtime and development environment? What LV version do you use?

  • Property nodes are all seriously affect performance

    LabVIEW gurus,

    I'm running continuously in some serious performance degradation by using nodes property to update the attributes of the objects of the public Service. A classic example is attached.

    I have 8 plots XY which are fed 600 SGL tip all the 200 ms - one very modest flow. Each plot is a dynamically instantiated .lives placed in one of the 8 sub-panels in a container of VI. The VI container also acts as Server data for charts, each of them sending their data in the queue for their own unique item. The entire architecture works great (~ 4% CPU load, see attached picture) until I by updating a node property to display the value of the value of the cursor there. When I activate the property node 'Caption.Text' of the XY graph to display the value of the slider, the CPU usage rises to more than 30%.

    As an aside, I'm developing on a platform of 2.1 GHz dual core with 4G memory with LV8.5.1, and the target machine is not nearly as strong. That's why 30% CPU on my plant is a problem - it essentially brings the target incorporated to its knees.

    I've included an example VI to run on your machine. Think of it as 'representative' of my biggest problems. The VI series update the CPU without the legend about 10% and 20% with updates of the legend.

    Finally, I tried to put the screws in the system of execution of the user interface. I also tried to postpone Panel updates, but this actually slows performance.

    Best regards

    No caption:

    Use captions only for noncyclical display. With the help of a text indicator should solve the problem.

  • Why Garage Band will not accept my password for Apple?

    When you try to download new sounds to my library of Garage Band that my Apple password is not accepted. Why is this, and how many attempts do before I'm locked?

    I guess that you are referring to the your Apple IDpassword. This password works in other Apple applications, i.e. iTunes, iCloud, etc.?

    You have more than one Apple, maybe you bought with a different ID of Apple GarageBand.

    You can view the history of your purchases using the iTunes application. From the Store menu, go to view the account. There is a section "purchase history".
