Hello,
I created a packed Library in my LabVIEW project through moving all my VIs in the created project library.After that, I can find a .lvlibp file in builds folder. But when I tried to open it with 'Class Member call', I can only see the .lvlibp file in the window. but I can't open it . What is the problem?What is the right manner to create a PPL , in oder to use the VIs in TestSTAND?Thank you for answering.
Hi all. I'm trying to use Labview to make my robot follow a black line but I'm having issues. My code only lets the robot turn one direction so I'm wondering what I can do to fix it. I attached the file. It's very simple and I know the reason why it only turns one way so I guess I'm looking for ideas of how to tweak it
I have the following code below for my NI9401 module connected to my computer via a cDAQ-9171
This code is built off the following example here: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000004AvPSAU&l=en-US
For some reason, the event will consistently fire only once. If anyone has an insight, it would be greatly appreciated.
Hello,
Using NI Package builder, I have to mention the destination path explicitly. This makes the package get deployed in a particular version of LabVIEW. Do we have an alternate method where we can make the package independent of the LabVIEW version?
I was trying to use the windows media player in my labview, but when I 
Hi there,
I got an USB to RS485 adapter that is connected to a 185nm UV sensor. I should use modbus RTU communication type.
I've read this article of modbus, thus i've created my own vi.:
I get Error Code: 538182 when i run the vi. I have the following modbus libraries installed: ni_lib_modbus_library-1.1.5.39.vip, ni_lib_modbus_library-1.0.10.23.vip
Note: Sensor is physically connected. If i use the application of the manufacturer then it communicates.
Could someone please tell me what is wrong with my code?
Kind regards,

We The People Hemp CBD
There would one say one is question specifically that keeps numerous potential clients under control: Is CBD maryjane and will it make me high? The appropriate response: no and no. CBD is non-psychoactive (it doesn't make you feel euphoric) and is viewed as very sheltered. Truth be told, CBD can really balance the psychoactivity of THC, the part of maryjane that makes you feel "high." Hemp and maryjane originate from a similar plant family, however are totally extraordinary in capacity, development and application. Pot for the most part has a significant level of THC and is utilized for therapeutic or recreational purposes.
I have develop a labview based system for my application, i want to entre few datas in my application like (Name / Number), i want touchscreen keyboard of windows to support labview, to do this. I donot want to write any code to call Tabtip.exe or OKS.exe for doing the work. I tried various solutions given by labview like using system control / using .Net container and including string and numeric indicators in that.
Hello everyone,
I am trying to follow an LV generated error (error_out cluster). My master machine gets the bundled errors of all slaves and displays the errors on the main UI. Looking at the errorcode I can identify the statemachine. The error happens in daqmx-start (-50103: DAQmx-start.vi:722003). I set probes at every case I use the it but the error is never thrown.
Is it possible to follow the error to its caller, since I am not always aware which VI labview calls when I am using the native VIs?
Hi,
I've been playing with the WebVI Module of Labview NXG 4.0. What really irks me is that although there is a dialog box, it only contains buttons and has now way of getting information from a popup back to the application beyond the button states.
What tried then was to embed an window.alert into a Javascript Library Interface. This doesn't work at all. Basically, I just modified the example from NI to call window.alert in the javascript add.js file. NXG just seems to ignore the alert statement completely (no errors or messages). If I create a new project and add a custom function which ONLY calls window.alert, the webVI runs as normal, ignores the alert, and spits out an unhandled exception with code 443012 at JavaScriptInvoke.
Is this a limitation of the NXG WebModule or am I doing something wrong? I've attached he javascript file and the jsli file...

Hello,
So i have a project use class and some other class which inherit from one generic class.
In the main vi, i have several if-else case and in each if-else case, i also have many if-else case,like 30 in average.
so right now, the problem is the wire in the main vi is pretty slow, but for some other vi and even a sub vi in the main vi is in a good wire speed,
Any suggestions about it.
Below is a screen shoot for the structure of the if-else case.
Hello gents, browsing the forum i found this old post that does exactly what i want to do with my tabs
I'm trying to recreate it in my VI but i can't do it, i can create the part with create > property node > pages so i get the reference number of the pages but i can't quite understand how to disable and gray the other pages while i'm not using them.
Can someone please explain it to me and possibly guide me through some steps?
Thank you in advance 🙂
I am installing NI-visa package and the message "No operation to be performed" appears. I don't understand it. How can it be fixed?
Bonjour à tous,
Dans le cadre d'un projet d'école, nous avons réaliser un programme qui prend des photos d'un échantillons via un microscope. Pour continuer, nous sommes à la recherche d'une fonction qui nous permettrait de récupérer la valeur du même pixel sur chaque image (les images sont en nuances de gris) pour pouvoir tracer une courbe.
Quelqu'un aurait une idée?
Merci beaucoup,
Guillaume

Hello,
I have been using LabVIEW 2017 on my Windows 7 machine for months now but suddenly I cannot load any of my VIs or projects. What I see is a popup saying "There was a problem sending the command to the program"; in task manager I can see the LabVIEW process using up the memory as usual, but it does NOT open as normal (which is different to the situation in the associated knowledge article, where it does).
From my internet search I can see examples of editing registry keys but there are quite a few LabVIEW-based ones on my PC and I'm not sure which one to edit, or even if editing registry keys is the solution!
Any help would be appreciated, thanks!
I have interfaced my Arduino Uno with LabVIEW using LINX. The first time I run the VI it takes some delay for the Arduino to respond (around 7 sec, Tx and Rx LED blinking time). After that the delay is tolerable with control. The VI I am trying to build has a requirement that values should update as soon as the VI runs. How can I control the initial delay ?
I need to create a CAN database with about 100 signals. I don't want to manually do this since I will make a ton of mistakes so I'd like to do this programmatically. I suspect this is not possible since I see no hits for this when I search the forums and the web.
Hello !
I'm new here and that's my first post.
I have a myo armband and a robot arm. I want to control the robotic ARM through the myo but I don't know how could I do that.
I've searched some information on google , but it's quite unclear.
Could anyone help me with an step by step algorithm ?
Thank you very much.
