I'm currently using LabVIEW 2015 (64-bit) and am encountering a Call Library Function error because my dll is a 32-bit version. Does anyone have or knnow how to create a "File Dialog Wrapper.dll" 64-bit version that I could try? I'm completely unaware of how to do anything to create or modify a dll. Any help will be appreciated.
Thanks, Josh
Hi,
I have a signal being read, I should activate another process if there is no difference in the value from the last 100 measurements from the signal (say around 1% deviation). Can anyone help.

Is there a way to read a tab delimitted text file and then write that same data to a csv?
I need to do this, but I don't know how to pass from one type of format to the other.
Can someone please help me?
Thanks.
Hi,
I am planning to build and application that distributes and collects data fro multiple clients via internet conection. I am quite fond of the datasockest server approach due to its simplicity.
I do not have much experience with datasocket and have two major concerns:
1. Though I have full control on the server side PC running the datasocket server and the server-side VI. (i.e. I can Disable firewall, define static IP , and most importantly -port forwarding). I do not have any control on the client PC that is running on the client application.
I have read article http://www.ni.com/white-paper/12402/en/. But still do not understand what has to be done on client side. I know for a fact that when the client will install Labview runtime and when he will run my application (exe program) he will be prompted by the windows OS to "allow access to labview program" (or somthing like that...)
Is this the only step my clients should do to configure there firewall. I am afraid I can not ask them to do any action beyond approval my application access during installation. Should I be concerned from other issue, related to security form the client side? (clients are pribably regular domestic clients, with avarege routers).
2. Please have look at the diagrams. is this an acceptable approach fro multiple client connection? (i do not plan more than 10 clients, so scalability is not a big issue.) the diagram ilustrates application runing on each clients PC. And VI running on server PC colecting data from 4 clients.
Thanks!
Hello there,
I´m using a sbRio-9637 to measure analog voltages. I was wondering why there is no option to put the chassis in Scan Interface programming mode? How am I supposed to use the I/O without the Labview FPGA module? Will there be an update or is a Bitstream for the FPGA avaiable?
Thank you in advance.
Best regards,

I'm usinge the C# Class NotifyIcon to get my application into the system tray bar of windows. Since I use this function, most classes get locked after running the application.
I found, that all loaded callback vis remain locked after running the application, therefore some typedefs are locked, therefore some classes are locked, therefore allmost all classes are locked.
I found the same problem with this example: https://decibel.ni.com/content/docs/DOC-9161
In LV 2010 SPI1 it works fine, but in LV 2014 SPI1 the VI CallbackVI.vi remains locked after running and stoping HandlingEventsInLabVIEW.vi. Also if you close HandlingEventsInLabVIEW.vi first and then CallbackVI.vi (both without any project) the 'GettingStarted' Window wil not appear and you need to kill Labview.
Since the problem appears in LV 2014, not in 2010 (I don't have other versions) I assume a problem with LV 2014 itself.
Any suggestions?
hello everyone, i'm working on a project for robot obstacle avoidance, i'm using fpga on myrio to control the position of the servo motor which sweeps a certain area defined by theta min and theta max with a step theta, an ultrasonic sensor is mounted on the servo and should take a distance reading at each step angle. the current position angle and its corresponding distance reading should be synchronised and corresponding to each other. then i will take this data to a host vi which is not a problem.
i was able to operate and control the servo motor as i want and i was able to get the readings from the ultrasonic sensor (i have hc sr04 and ping) on the fpga separately, however, when i try to make them both work at the same time, i have no luck doing so.... i have tried many things and searched all over.... can anyone please guide me what to do?.... i have attached the last fpga code that i came up with, i dont know what is wrong with it.... thanks)))
hello, i am working on my final project to controling temperature,
at first i use a thermistor, and now i want to change it to a thermocouple. i was made the Vi program for it, but i still dont know how to connecting it.
i attached the file down there, and i wanna ask is it posible to swtching number 1 with number 2 as attached in "subs.png" down there
i hope someone can help me
thanks.
I created a LabView VI using the "User Interface Event Handler" template.
While one command (event) is executing, I would like to be able to process and execute additional user events.
For example, button 1 executes a power interrupt by sending a power off command to the remote device, waits 10 seconds, then sends a power on command.
While I am waiting 10 seconds to execute the ''power on' command, I'd like to be able to run 'button 2' and so on.
Thanks for your help...
I'm trying to get the oscilloscope reading from channel 3 and put it into the waveform V_RECT, but it isn't working for whatever reason. Can anyone help?

A colleague of mine created an executable with LabVIEW 2011 that uploads measurements to a database. It runs on a laptop with Windows 7 but it won't run on a Windows 10 laptop. I can edit the original VIs in LabVIEW 2015, but creating a new executable in LabVIEW 2015 does not solve the problem. It will run in Windows 7 Compatability Mode on the Windows 10 laptop, but I would like to not have to select that option every time I install the executable on a new laptop. Any suggestions?
Hi,
I am accessing LabVIEW from a third party test sequencing application (which uses TestStand for sequencing). Occasionally while running our test, LabVIEW crashes and provides the attached lvlog report. Help interpreting this report would be appreciated. Also, if there is more useful information I could provide, let me know about that too.
Thanks,
Billy

Hello,
As a test set up I have created a BMP image, which I then decompose and then want to reconstruct.
Decomposition:
Into 1D array, 30pixels at a time, row by row (180 pixel wide image = 6 iterations) as can be seen in the first while loop of the image.
Hence first 30 elements of the 1D array will be pixels 0,0 - 0,29, next thirty will be 1,0-1,29 etc.
I then attempt to reconstruct the image, and it looks like it works except for the last row of 30 pixels where the image does WEIRD stuff, it looks skewed...
I have attached both my labview code, and picture of the reconstructed image.
The decomposition is a little confusing and if necessary I can provide a picture description.
Thank you.
Hello,
I have some questions about LV configuration:
1. Is it possible to modify appearance of waveforms? Colour, 3D effect, font...
2. How can i join 8 graphs into a single block. I explain, i have 8 sepparate graphs but i want to graph them into a same block but in different lines.
3. Is it possible to delete the background grid?

Hey guys,
So my problem is that I have a list of known selections that I would like in something like an enum or ring control, the user will have to click on one option and something will happen unique to each selection. the program will have many pages where the enum/ring will be present and on each page the options available will be a relatively unique grouping of the known values.
basically options 1 - 6 are already known to exist.
on page 1 the drop down shows options 1, 2, 3
on page 2 the drop down shows options 2, 4, 5, 6
....
every page will have some combination of the options.
also this isnt random, im pulling the page and the list of items for the list from a database.
Im trying to think of a good way to do this, my guess is my options are rings or enums but if theres something else I could use to generate lists like this at run time I have no problem looking into it. I was looking into using the strings property node to take the strings of options from the database and populating the ring control but how do I keep the value of the ring always associated with the proper string? I could use the value and string property and just pre associate the database strings with the proper numeric value.
I'm just wondering if there's a better way to go about this.
Thanks for any help
Looking for a way to read the units of channels in a task. Right now the only way that I know of doing that is to actually read data then query the data. In this instance I do not want to do it that way I'm looking to read the units from the task. I do have custom scales applied so I know that complicates things.
Thanks
Greetings everyone, for datalogging purposes, I need to query data from a DAQ, add a timestamp and post-process data, then save it all to a .tdms file. I also need to create a data buffer for a certain event, which I intend to store using a 3D array, I only need 1 cycle of data, so it would have 2 pages, 1 current and 1 backlog. Problem is, for some reason, it is only storing a single row of data, instead of whatever amount I send from the post-processing loop, I can have a 2d array of 2000 rows per 6 columns, and it will only store 1 row, what am I doing wrong?
Running into a weird problem with Enums. I'm trying to dynamically populate an enum to allow for some dynamic dispatching during a user input phase. I'm almost done, and this happens:
The front panel on the right is the "Setup Enum" vi. On the left is the main VI, with a strictly typed enum control reference going into that VI. I've attached the vi hierarchy; open "Choose Curve.vi" to troubleshoot.
