Control of first level VI by using controls Subvi indicators?

I'm still learning LabVIEW, so apologies if this is pretty basic.

I'm trying to declutter the façade of my main VI by moving some controls less frequently used in a Subvi. The idea is that when the user wants to set these controls:

(1.) the user presses a button on the main VI to launched the Subvi front.

(2.) the Subvi front opens and the user adjusts the values of controls Subvi.

(3.) the user presses a button to close the Panel front of the Subvi.

Ideally, the relationship between indicators of higher level and the Subvi of control must be the same when all the controls and indicators have been on the main VI - i.e. when the user plays with the controls in the Sub - VI the main VI must always be running and its indicators should respond to changes on the Subvi real-time controls.

I guess it's possible, I'm not sure that eactly how to build this relationship between the main VI and the Subvi.

I just need a little nudge in the right direction on this one, thanks!

Mike

You must create references to controls in your top level VI and pass them in the Subvi.  Then have the Subvi write property as the value nodes using these references.

  • Controls and indicators combined in the same Bay clusters

    Hi all.

    In the attached picture you can see an indicator (or perhaps, control) that I want to use with the following behavior:

    -C' is an array of clusters. Each cluster has two Boolean, a string and a path (a checkbox and a button "sequence Asignar").

    -I want the first two components as indicators (the chain and the path). I mean, they contain data that it is introduced previously in the application, and I want these indicators only to show that information.

    -I want to have a button ("sequence Asignar") associated with each table group. When I push the button, I want to perform an action (different for each cluster of the table), the button must be a control.

    -Box has a behavior similar as the button.

    I know there is no way to combine the controls and indicators in the same cluster or matrix. I tried also with local variables and methods of 'value', but I can't solve my problem.

    Please, any suggestions?

    Thank you

    Here's a trivially simple example how you would rewrite some false indicators based on changes in the controls.

  • A way to group controls and indicators on the Front Panel and that they can be made Visible or not as a group?

    I would like to combine several orders and LEDs on the front panel in a group in a way that allows me to do the whole group Visible or not.

    I tried to use a Cluster, but it has a side effect that all elements must be inside the controls or indicators, but not mixed.

    Is there any graphic element, like a panel that can contain other controls and indicators on the inside and make them Visible or not as a group regardless of whether they are commands or the LEDs?

    Good suggestions on how to do this?

    Thank you.

    The tab control is still not my favorite, appearance but it's a way fast and effective to show and hide groups of controls and indicators.

  • List of controls and indicators

    Hello

    Maybe I forgot something very simple.

    I am trying to clean my overloaded façade and edit it in different tabs. I have a lot of controls and indicators and property notes to make them visible or not. To make sure that I don't forget everything in the new façade, I would like to have a list of all the controls and indicators used in my application. A solution would be to create a new local go, select and write down the list complete, what is shown. Next would be to type all names in an excel sheet to a checklist that must be displayed where and when on the new front cover. Is there a better way, which is to export the list of Labview in a text file?

    As... of the controls and indicators how?

    With the help of the tabs is certainly a good idea to help organize your front panel, but if you use the tabs just so that you can have hundreds of controls and indicators on your front maybe there is something else you could do to improve your code similar to the use of several different types of controls (tables (, clusters, etc.).

    But to directly answer your question, Yes, there is a way to get the list of all the controls on a panel like this:

  • VI marking as first level during construction

    All by building a Bachelor's degree in LAW, is it possible to specify screws in the upper level. I wasn't able to see an option for this in the construction specifications. I'm using LabVIEW 8.6.

  • FPGA controls and indicators appearing is not in the node IO FPGA.

    I don't know there is something simple, that I do not. I use the pure mode of FPGA on my sbRIO. I have several controls and indicators that I added to the FPGA code since the last compilation. I compiled the code and ran it again once or twice. However, the new controls and indicators do not appear as options in the FPGA to e/s nodes on the side of the RT. What is missing?

    Thank you!

    Hi Adrien,.

    How you bind the host RT code to FPGA code?  It seems to me that you are accidentally linked to an earlier version of your FPGA code that does not include new controls/indicators that you are looking for.  Check the Open FPGA VI reference VI in RT to see if you're related to the FPGA VI, the right Specification to buildor latest Bitfile (xxxx.lvbitx).

    If you link to the VI or the specification of the Build that you consistantly use to compile, you won't have to worry of re - bind your RT and FPGA VI after each compilation.  If you bind to the bitfile directly, you will need to update your RT references after each compilation at the last bitfile.

    Kind regards

  • How to release the source code (only) for first level VI?

    Hello

    I develop an add-on for an application that I have. The demand is large (more than 1,500 VI) and the screws are set up to compile with for most of the default settings (there is a first level VI, some with visible front, most of them are not visible).

    The customer wants that source code for the work that I do, and he will use the many existing Subvi. The addon itself will be a Subvi (I have a Main.vi that basically opens 'front' and it is a new screen). The sub - VI existing basically make data collection and treatment, and the new code will perform additional processing and have a nice GUI for existing code. The customer wants the source so that they can make changes as needed.

    Is there an easy way to simply provide the source for the first level VI? Basically, I want to give them M.vi, where M.vi name n.vi, o.vi... etc, but o - z.vi should be non-free. In addition, M.vi is called by Main.vi, which opens A screens - M.vi

    One option is to copy the entire application, then open each sub - VI and save it without Source Code. But with so many files, this seems like a bad idea. So, I also maintain two applications.

    Good ideas out there? It seems if easy in other languages (using object files) it looks like there should be a solution here I don't see... Thank you!

    Ah! I completely forgot to Save with Options. It's been so long that I had to deal with this type of problem.

    OK, to ensure that:

    I opened my first level VI, saving Options with-> apply the password (or remove diagrams) and then give it to them. I also provide a normal backup of their VI, with source.

    I still about 100 screws which are called dynamically are not part of the VI treeand I would still have to re - register with a password, but it's better than every single VI. Thank you!

    Use the option duplicate hiarchy and preserve...

    apply to all...

    at least as far my memories are good.

  • Problem: controls and indicators not updated when to open the front panel

    Hello

    I have a strange problem when I progamatically open the façade of a subvi: for some sub-vis controls and indicators are correctly updated while others are not (ie the controls display the outdated values).

    Here, I have created an example that illustrates this. 2 sub-vis are * exactly * the same thing, but only a day watch control when I open it (with the sub - vi previously closed of course).

    How is that possible?

    What should I do to have the controls implemented to date to the last value of the * last call * when I opened the sub - vi?

  • SQL to get first level parent counties only

    11g,

    Hello world

    I have a table like

    Create the table TempEmp

    (number of emp_id,

    emp_name varchar2 (100),

    number of mgr_id,

    report_submit_status varchar2 (1)

    )

    Insert into TempEmp values (1, 'xxxx', 2, 'Y');

    insert into Tempemp values (2, 'YYYY', null, 'n');

    insert into TempEmp values (3, 'vvvv', 2, ' don't);

    insert into TempEmp values (4, 'tttt', 1, ' only)

    I need to show the output of the first level below the EMP is entered and the counts where status = ' not grouped by them.

    For example,.

    If you run the query for emp_id 2, 1 and 3 reporting directly to him. and the 4-1 statement. If the output should be

    County Assessor first_level emp_id where report_submit_Status is N

    1                                                                              1

    3                                                                               1

    If I ran the sql of emp_id code 1, the output would be

    County Assessor first_level emp_id where report_submit_Status is N

    4                                                                              1

    That way the hierarchy could be up to any level, as in an organization.

    Any help would be appreciated

    Thank you!

    Licensing - in particular for fonts - is always a big pain - and even if you have a lawyer paid handsomely on the case, it is always a challenge to navigate in all licenses of the difference and the different situations.

    In reality, the chances of trouble to use a font Adobe provides as part of the suite Creative Cloud is little or none - even if it's TECHNICALLY in a kind of fine print.

    However if you are doing a project where you must provide tangible evidence that everything is legally more High Council (which you have to do a lot of time for projects that are funded for example the Government), then things can become difficult.

    In the case of Myriad Pro - even though the creative cloud agreement specifically lists the fonts in the list of the restricted fonts - you can always register Myriad Pro through Adobe's Typekit service (see: Myriad Pro |) Typekit) so that circumvents this problem.

    My advice - if you need evidence that the fonts of your use of any good - then I would contact Adobe directly, in order to have their response in writing. See: https://helpx.adobe.com/contact.html

    If you are just doing a personal project, and you put the work on YouTube (even if you get advertising revenue as part of the YouTube partner program), and then the case to get into any kind of trouble because of policies is VERY thin - but if you want to play it is really safe, it is best to do your research , and make sure you have something in writing say that everything is perfect.

    If in doubt - talk to a lawyer, because they will be able to do a risk assessment appropriate - even if it is somewhat a grey area.

    We had similar issues trying to license of Adobe Stock content - a few clauses in the agreement that is very unfortunate entertainment lawyers.
