ECU Measurement and Calibration Toolkit datastream without database
Hello,
i use the ECU Measurement and Calibration Toolkit for measuring the ECU Datastream. My problem is, that i receive less data then configured in the A2L-database. So my idea was, to read out all datas which the ECU is sending. Afterwards i can compare the amount of received data-channels from the ECU which the amount data-channels in the A2L-database and delete all channels which are not received from the ECU.
Now my problem is, that i don´t know, how i can measure all datas from the ECU without selecting the channels one by one.
thank you i advance.

Build Installer Missing Packages (don't know what to install)
Dear Community
After starting with installation of LV2019 i observed that i have had big problems in building applications in LV2018x64 (error 3 could not load front panel)
This has been solved by removing all 2019 stuff and reinstalling daqmx 18.5.
Now the application builds fine again.
The big problem is now that the building of an installation package of my program always wants me to put in a CD with some unknown component.
I tried a lot of things installing LV2017 and device drivers and DAQmx's of different types but nothing solved the problem.
At the beginning of this problem it said that the NI VS2010Msms* is missing.
Then it asked me to put in the source NI mx LabVIEW Control Installer.
I pointed to any location where i have NI installable software but it never was the correct one.
I am really confused what I can do.
Here are some screenshots to see the details.
I am also confused that there are some check boxes not changeable (is this normal or the origin of the problem).
I also tried to make a absolutely new installer specification which should only use the recommended installers. In this case the problem is the same.
Thank you for your ideas to solve this problem.

New LabVIEW download page does not work
I am reinstalling everything on a new computer. so this morning I go to get LV2018 and find this new download page
https://www.ni.com/en-us/support/downloads/software-products/download.labview.html
Okay that's nice and easy...
Except after I chose the version and hit the Download button NOTHING HAPPENS.
Is there some special browser plug-in I need to make this work?

A quick query about LV functionality
Given this vi that controls a motor based on some sensor data, I have some logic that determines the next motor state (based on the previous state & some sensor input). Furthermore, I need to test/evaluate different logical methods to determine the best motor/sensor approach for our application. This currently leads me to the practice using nodes/wires to encapsulate the state logic into a subVi, then trying the sub in the larger test vi.
My question is, can I compose the logic in C and make this usable (by some means) to the test vi, instead of wiring the logic into subVIs? Since the logic can be distilled to primitive data types, it seems like it would be much faster to type the transition function into C than it would be to encode it into a subVi w/wires & nodes.
Am I making any sense here? I've been using LV for about four weeks now. I'm wondering if there is a method of "compiling" a function written in C into a node that can be placed into a vi. Thanks in advance for you help.

Install LabView 2019 on hard drive other than C:
So, I recently downloaded the NI software bundle Spring 2019 because I wanted to upgrade from LabView2018 SPI1. To my disappointment, NI Package Manager doesn't allow me to choose a destination path and installs everything under C:/Program Files/ . Unfortunately, I don't have enough disk space on my SSD, so I wanted to have the option to install it on my other HDD, D:/.
This was possible when I installed LabView2018 SP1 in the past. Please note that I want to install the FPGA module with the Vivado 2017.2 compilation tools, so disk space is a serious issue...

IEEE write converted from C
Hello all. Forgive me for the somewhat basic question, but I'm trying to control an old magnet control gaussmeter (Varian FR41) and the old C code looks like this:
{
long temp;
int z1,z2,z3,z4,b1,b2,b3;
float b;
double gauss,hv=9555.,magconst=.069,Mass=171.;
if (ieeeinit()==-1)
{
printf("Cannot initialize IEEE system.\n");
exit(1);
}
gauss=sqrt(Mass*hv/magconst);
temp=10*gauss;
b=temp/10.;
z1=b/1000;
z2=b/100;
z3=b/10;
z4=b;
printf("\n\r %f %f %d %d %d %d",gauss,b,z1,z2,z3,z4);
b1=z2+z1*6;
b2=z4+6*z3-160*z2;
b3=(b-z4)*160+14;
printf("\n\r %d %d %d %d",7,b1,b2,b3);
ieeewt("output 08;");
ieeeprtf("%c%c%c%c\n",7,b1,b2,b3);
}
I'm having trouble with the conversion to LabView in two areas. First, the in the line
b=temp/10.;
I do not know how to reproduce the "." element selection in LabView.
Lastly, I can't seem to get the
ieeeprtf("%c%c%c%c\n",7,b1,b2,b3);to communicate with the instrument using the GPIB Send Message.vi. Is there another solution to sending characters to the instrument through the GPIB hub?
Thanks,
Jesse

updating distributed application
I have a distributed application that I had sent to a customer, including the installation file with LabVIEW real time engine. After testing it, they wanted several changes, one of which included a sub VI not included with the original. I rebuilt the application, then sent them the .exe file. The customer deleted the previous version and copied the new version of .exe to their computer
The customer has commented that the file will not even run.
1. Is the problem because I only sent them the .exe (application) file, and not the .aliases and .ini (Configuration settings) files? I guess that makes sense, now that I read the type of folder.
or
2. Because I added a new sub vi to the program, do they need to have a installer file? I noticed one of the steps in the installer requires all files to be called out. This kind of contradicts the idea that if a customer downloads LabVIEW run-time engine, all they need is the application file.
or
3. Do they need both? Both files together was 1.2GB large, because I had to include an extra installer, DAQmx Application Development Support.

Independent instances of same subVI
Hi, I am making a control panel for eight temperature controllers. The controllers communicate to labVIEW with serial communication. I made a subVI that has a while loop inside to display temperature values every certain time. In the main VI I call twice this subVI with independent parameters (inputs) and control the open/close of their front panels with buttons. Although, the Hierarchy diagram shows that both references points to the same subVI so I cannot open them independently. Can you help me, please?
Main VI:

GOOP Development Suite is Missing
I'm installing LabVIEW 2018 onto a new computer that I'm trying to setup for development work.
Whenever I open the project I get the following error:
C:\Source\CLV Station\Core\Source\WebServices\WebTool.vi (WebTool.vi)
NI GOOP Development Suite support for LabVIEW 2018 is missing and is referenced by the following VIs:
Twice, I have tried installing the NI GOOP suite to try to get rid of this error. I received the error after each installation.
The snapshot below shows that the VI Package Manager seems to believe that the suite is installed. However, when I load the project it gives me the error indicated above.
I would appreciate any help toward resolving this issue.

Large, Pixelated Cursor in LabVIEW 2018 SP1 on Windows 10
Greetings,
I have encountered a weird problem with LabVIEW 2018 SP1 (18.0.1f2) and the cursor in the development environment. The cursor is excessively large and pixelated. I believe it is being rendered at a lower resolution, and this is related to my high DPI screen. Please see the attached screenshots for examples of the problem. I acknowledge the fonts will be fuzzy and pixelated with a high DPI monitor.
Interestingly, this does not occur in LabVIEW 2015 SP1, which I also have installed. Please see the attached screenshots.
Summarized system information:
- Surface Pro 6
- Intel Core i7-8650U CPU @ 1.90 GHz 2.11 GHz
- 16.0 GB Memory
- 64-bit Windows 10 Pro
- Windows 10.0.17763 Build 17763
- 512 GB SSD
- Intel UHD Graphics 620
- Display Settings: 200% scale (Recommended), 2736 x 1824 (Recommended)
I am not running in tablet mode. I am not connected to any external monitors. I have read and tried the instructions in the "All the Main Application Windows in LabVIEW are Tiny" and the "Inconsistent LabVIEW UI Behavior with Multiple Monitors on Windows 10" knowledge base papers. If I disable scaling for LabVIEW, then the cursor is correct, but the front panel and block diagrams are tiny and nearly unreadable. I will mention, disabling the high DPI scaling fixed an issue I had with NI MAX.
I have seen the "LabVIEW and display 4K (3840x2160)" post as well. I tried halving the resolution and scaling, but then I get vertical or horizontal black bars on the screen. I also tried playing with the scaling and resolution, but regardless of the changes either the cursor looks good and the rest of LabVIEW is unreadable/unusable or the cursor looks bad and the rest of LabVIEW is readable/usable. I also think this is a different issue than the 4K monitor because only the cursor appears to be affected and I only have the problem in LabVIEW 2018 SPI.
Additionally, the cursor only appears to be large and pixelated within the block diagram and front panel. As soon as I move it to the menus or any context/pop-up menus/dialogs, the cursor changes to the system cursor and looks fine. Has anyone else experienced this issue? I am open to suggestions for potential workarounds.
Thanks,
Chris
