LabVIEW

Have you ever used LabVIEW and found it difficult to communicate to several VIs? Have you ever struggled to create sockets that communicate to just a couple of VIs? Have you ever wished that there was an easy way to integrate your VI with an exisiting C/C++/Java/... application? Have you ever imagined how cool it would be to control your VI from your smartphone?

Hi, hope you can help me.

I have installed RTI DDS v 3.1.1.11 toolkit on my PC and it works fine publishing and subscribing data, so now, I want to do the same but in my cRio 9053, so the getting started document says that I should install the software by using NI Max; however, I can not find the RTI DDS toolkit in NI Max. Is there a compatibility problem? 

I am using Labview 2021SP1 32b, NI Linux RT image 21.5. I hope you can help me. Best regards.

Hi

How we can frame this enum SpeedRequest Speedcmd using Labview to avoid data mismatch;

First, I use RTI monitor to show this is the datatype of the subscriber (not LabVIEW) that I need to talk to: 

enum IDL::Common::Message_type {
@default_literal
status_issued = 0,
command_issued = 1,
command_success = 2,
command_failure = 3,
command_pending = 4
};
//@Extensibility EXTENSIBLE_EXTENSIBILITY

My project involves using RTI DDS (v2.2.0) in multiple different LabVIEW applications, some of which are running on the same PC and some of which are running on other PCs or RTs.  My goal is to have each application keep a record of all applications that are currently communicating on the same DDS Domain.

I have developed C++ DLL by using the C wrapper that is used for various languages. At present, I can use in Python & C#. I have to find the way to read it in same in LabVIEW.

I use visual studio have installed OpenCV on c:\ added include directory and the .lib files for my project,  & I have created a variable in my DLL and I use that during #include <opencv2/core/core.hpp>.

I'm very new to DDS for LabVIEW (and in general). Am I right in saying that LabVIEW string arrays are not supported? Seems if I try to use one, all the Vi's that are generated are generated in an unexecutable state

I am attempting to define a cluster as a DDS topic that contains multiple numerics and multiple arrays interspersed throughout the cluster.  However, if I attempt to add a numeric after the array definitions (see attached photo), that the topic is no longer being generated (i.e. I can't examine the topic in Admin Console).  Is it a requirement that all arrays must be grouped at the end of a cluster definition in order to be used as a topic?  Thank you and forgive me in advance as I am relatively new to RTI DDS and very new to LabView.

Hi LabVIEW developers,

We are working on the next version of the RTI DDS Toolkit and we would like your feedback!!

Currently, LabVIEW arrays are mapped as DDS arrays. We are considering replacing DDS arrays by DDS sequences. Sequences can be initialized to a length of 0 and then be resized as needed. Pretty much as LabVIEW arrays! The behavior will be something like this:

LabVIEW 2013; WIndows 7 AGM; LabeVIEW Integration 1.0.0.87

If one has a cluster that contains other clusters, must the key ALWAYS be contained in the top level Cluster

This works, when the key is contained in the top-level

ClusterType OuterCluster
{
   data;                            <Can use as key!!!  :)
