How to operate the Subvi?
Hello
I use a VI instrument control and I used a Subvi to begin feeding after a certain point. I created a simple model of two-lane in the Subvi which includes just as an input error and mistake them as output connected to the respective terminals to VI main. The Subvi has 5 entries of order I made the default values so he will always perform with the values. These values act as an input for the power supply I'm controlling with the Subvi.
Now when I run my VI it does not start the sub VI, it won't run the control values and gives 0 input to the PSU, so it won't work. I want that sub - VI to run when I run my hand VI. Am I missing something? Sub - VI works perfectly when I try to run it separately.
That many things should be done when we connect all Subvi in primary VI.
Thank you.
LOCAL VARIABLES!
Your problem is that you have what we call racing conditions. Learn to think in data flow. A function will run when it has all its entrances and will display its data when it is done running. So the only variable local waiting to run? NOTHING. Thus, they work immediately, return the default data.
The solution is quite simple, use instead the son.

How to get the Subvi (the virtual path is in .exe) reference in Run Time System
Hello world
The problem is how to get the reference of the Sub - VI in run time system, when the Subvi is in .exe after construction.
More details:
Top of page vi called the Subvi dynamically, so that the Subvi is always included, and the source object is the application.exe.
After the above configuration, the Sub - VI will be the application.exe. For example, the path of Subvi est...\application.exe\SubVI.vi
So, how to get the reference of the Subvi in Run Time System?
I can't do it when you use 'open reference VI' with le...\application.exe\SubVI.vi path in the run time system.
In fact, I can create a file to include the Subvi, rather than build the Subvi in application.exe, then I can get the convenintly reference. But this isn't my favourate average.
Thank you
chenyin
That is the problem. Call a Subvi dynamic means users could change, but it is also very attractive.
The dynamic call should be used in a user control, but some parade can avoid problems.
It depends on why you use dynamic calls...-online 2 main ways:
-Dynamic call are used to maintain a scalable framework for the code without acting on the executable file-online a single VI distribution managed by the administrator/developer
-Dynamic call are used to provide a collection of "external" characteristic that could be enriched by the administrator/developer. For example, you provide your customers a set of selectable custom signal filters in the executable.
In 2 cases, you are only able to assess the skills of the users to know if there is a risk of damage, if there is a change.
So to stay only master a parade might be to provide dynamic VI without a schema, but with the problem of maintenance, since no in-place editing and more attention to manage distribution.
Another way is to hide the actual distribution to user-online call dynamic VI but it without name as *.vi but others (a repellent name as system of OS name ) or simply without extension in order to attract not user... but that's debatable...
Another more difficult but more secure method is to create a consistency check before your routine (version, user, modified date,...)

Hi krzysiekrk,
To be honest, your ad is a little hard to understand and I don t understand why you installed another wireless network card.
I think that the new WLAN draft N card is not compatible with your laptop so it boot doesn t. In addition, you can use project t N if you have only 2 antennas WLAN. N project requires 3 antennas.Then ask a service provider authorized in your country if guys can order a new WLAN card compatible.
A few weeks ago, I replaced the card of wireless network from a notebook of s from a friend and it was Intel 3945ABG card too. This wireless network card is still available and it will be produced so it s not one end of product life.

How to make the Subvi when I make use of the structure of the event
Hello everyone
I don't really understand how to make use of Subvi when I use the event structures in vi?
When just make buttons on the controls Subvi connectors and assign them the vi stops working as I expected.
I've added an example vi I do not operate as a Subvi.
Thanks for advantage.
I think raise you an event to change value via the input connector, that you hope to do. One ugly semi solution is to get the button references and make a Value property (Signal).
A better solution if you want Hasina events in a subvi is to record user events and send the registry-event thread for the sub - vi, where you can use these events to the event structure. Check that the user created events and examples of dynamic event.

How to operate the system Exec (Batch file) as an administrator
Hello
I have a batch file that I need to run. But it should work with administrator access.
How can I run a command line by using the Exec.vi system as an administrator?
I was able to "solve" this problem with a work around.
I installed the 64 bit version of LabVIEW that calls the appropriate 64-bit shell to execute the TFTP call.
I do not understand the lack of functionality in the 32-bit version and the 64-bit version seems to work.

How to open the subvis before running software?
Hi all
I wonder if there is a way open subvis with my main vi and have it run at the same time the main vi is running? As soon as I double click on the main vi, I want the panels front-end Subvi to pop up with the vi main and run them all when I click on run on my main vi. Thank you.
To get the sub vi FPs to open when you call, go to file > VI properties, select the appearance of window option in the dropdown menu, click Customize and check "see the front when it is called.
At least the front of the auxiliary of the screw panels, which will open as soon as they are called in the main vi.
As for having all FP open just by opening the main vi, but before you run the vi main, I'm not sure.
Edit: a typo in
Edit 2: Under "before show Panel when it is called" is another option. «Open front when load.» Looks like what you want. That check for all of your sub vi

You must post the specifications for your PC.
I think that you have a HP or Compaq, if so, there should be software app for it on their website. Probably of Cyberlink you Cam. (should be responsible for tick menu)

Hi, I'm new in Labview. I need help for:
1 change a program multi-function in order to record the data of three cards daq (devices 1-3) and output through the map (1 unit). The current program was created to record and output signal of one of the card (1 unit). I try to choose multiple devices when I run the program, but there is an error 200558 shows "a task cannot contain multiple independent devices. Create a task for each independent device.
2. change the duration record for a longer period, for example: 0.1 s. Currently, the recording time is s 0.009971.
I joined the multi - funtion.lld. In this library, "des_v2_Multi-Funtion_Synch I - AO.vi" is the program that I need to change. I've also attached a file of input for runing the program signal.
Thank you very much!

Hello Jshen6,
You can have different examples of VI if you do not use the same version of LabVIEW. I am currently operating on LabVIEW 2013 SP1. Whatever it is, this article should be useful to you that he describes in detail how to synchronize multiple tasks of series M.

How to operate the ListStyleButtonField!
Hello
I have a question about the ListStyleButtonField. How can I make each field in the list to go to a screen spicific class?
FirstField = ListStyleButtonField
new ListStyleButtonField (button1left, 'Customer', buttonRight, 0);
() firstField.setChangeListener
ce) ;
Add (firstField);
ListStyleButtonField = secondField
new ListStyleButtonField (button2left, 'Contract', buttonRight, 0);
Add (secondField);
as it is not in the API, you must link to the source:
http://supportforums.BlackBerry.com/T5/Java-development/implement-advanced-buttons-fields-and-manage...or directly
https://github.com/BlackBerry/samples-for-Java/BLOB/master/advanced%20UI/src/com/samples/Toolkit/UI/...as you can see in the source code, all actions invoke a fieldchange event. This can be captured with a fieldchangelistener, that you are adding it only to the first field (perhaps you obmitted the second).
If you implement fieldchanged in your screen you must discern whence the event. to do this, declare the fields on the scope of the screen and check if the parameter of the method fieldchanged field is the field you need.
example:
' Public Sub fieldChanged (field field, int context) {}
If (context! = FieldChangeListener.PROGRAMMATIC) {}
If (field == okButton) {}
