      I've got a tool that searches through a bunch of VIs for stuff. That part was easy. Now I've got an array of GObject refnums, I need to present the results to the user as a list that the user can click on to visit each of the found items. Basically, I want the functionality of the Search Results Dialog Box, but without the search part. The one built into LV has no exposed API. Is there a publicly available replica that someone has built? My Googling around didn't find anything, and I really would prefer not to reinvent that particular wheel if I can avoid it.

      LabVIEW's built-in XNode editing tools are enabled using a license file, rather than a simple INI toggle. Presumably they do this for stronger discouragement from unofficial use, as hacking one's way past that feels a lot more "shady" than just adding a line to a config file.
      But what about the Linux and Mac versions? They don't have a license manager, so how is XNode development enabled there? One might guess that those features simply aren't compiled into the released builds of those versions, but there is actually precedent to suggest otherwise. VI Scripting used to be similarly restricted using a license, but then they made it public. At the time, LabVIEW didn't have a toggle in the Options for it. But they didn't need to release a patch to add one. Instead, they simply published their formerly-internal license file, and set their activation server to accept requests to activate it. And yet, Linux/Mac users weren't out of luck: it turned out that for them, it actually was just a configuration key.
      The VI Scripting license had the internal name "LabVIEW_Scripting(_PKG)". The Linux/Mac configuration key was "Scripting_LabVIEWInternalTag".
      At 17:48 in this video, several XNode-related configuration keys are shown, likely found in strings in the EXE or resource files. One of them is called "XNodeDevelopment_LabVIEWInternalTag". Guess what the internal name of the XNode Development license is.
      I don't have the Linux/Mac version to test with, but I know a pattern when I see one. The following command was given in the readme for the VI Scripting package for Linux:
      echo -e "labview.Scripting_LabVIEWInternalTag:\tTrue" >> ~/.labviewrc Here are the Mac instructions:

      If you have either of those versions, it's probably worth a try: follow those instructions, but replace "Scripting" with "XNodeDevelopment", and see if you can open an XNode in the IDE, or create one from File->New. (Also, in the case of Mac, replace 8.6 with your actual LabVIEW version if necessary.)
      (Here's where I got my information about enabling scripting: https://forums.ni.com/t5/LabVIEW-APIs-Documents/LabVIEW-Scripting/ta-p/3535340?profile.language=en)

      Hi guys. This semester I'm starting a course system development for control and automation engineering, witch will be based on LabView. Therefore, my University doesn't have a NI hardware, even a MyRIO for us to test our VI and the teacher said that we should test our projects with our own Arduino...
      So, I have a little experience in Arduino and I know the basics for LabView. Now I'm in a point that I know that with Arduino I'll not take the best from LabView. I cannot even deploy a code to it.
      So, there is where my question comes in...
      I'm looking for a new board better then Arduino to use in the classes. I would buy a MyRIO card if I had the money but in Brazil this board is too expensive for me
       Witch one should I get that is closest to myRIO and less expensive than that? I would like to try de deployment of a VI and FPGA..... Is this possible?
      Thanks a lot for the help!
      Regards

      Hello. I need change some code for SbRIO-9626 with LabVIEW 2018. I have code from LabVIEW 2015. Right now I have only LabVIEW 2018. And I worked with it for SbRIO-9627.
      LabVIEW FPGA, LabVIEW Real-Time, NICRIO1800 driver istalled.
      And I install Xilinx ISE 11.5 Compilation Tool too. 
      When I start compilation FPGA VI I got error about problem with compilation too (see attachment picture).
      Could you tell me how I can solve this problem? 
      It is very important.

      View File XNode Editor
      8 Years ago the first version of the XNode Manager was posted to the code repository in an attempt to allow the editing of XNodes.  Being a fan of XNodes, but knowing that the XNode Manager is pretty limiting because of its age, I set out to make a new version with similar functionality.
      The XNode Manager had a blank XNode, and blank Abilities that it just made copies of.  This is fine but then the abilities and XNode are quite old.  There were many new Abilities added since version 8.2 and you can't add them using the XNode Manager.  My XNode Editor reads your LabVIEW resource and populates the list of abilities to create from the ones that are possible to create.  Then VI server is used to create the XNode, State control, and Abilities.  This sets up the connector pane like it should and should work with all future versions of LabVIEW, until NI changes something that breaks it.  It also reads in the XNode Ability descriptions to help understand how to use the new ability VIs.
      In addition to being able to create and edit XNodes, you also can edit the XNode icon, and description, along with adding any new abilities.
      Be aware this uses several private functions, and several undocumented features that could be potentially bad.  I did a decent test to make sure memory leaks weren't a problem and I made several XNodes and Abilities and it seems stable.  But at the end of the day if it blows up and crashes, don't be surprised, you've been warned.  The original thread with discussion and progress on this tool was started here.
