Here I have kept systemexec.vi it is running one python file. But i want to terminate systemexec.vi execution after 10 minutes if it is still executing python file. I have added vi for reference.

HTTP GET body with special characters
Hi,
I try doing some html parsing and what I have noticed is that the HTTP Get vi does not return the local characters properly.
For example, a headline in my browser looks like this:
"La "tormenta de fuego" que arrasó Dresde hace 75 años y se volvió la "vergüenza" de los aliados al final de la Segunda Guerra Mundial"
The HTTP Get VI returns this in the following format:
"La "tormenta de fuego" que arrasó Dresde hace 75 años y se volvió la "vergüenza" de los aliados al final de la Segunda Guerra Mundial"
Is there a way to display the body with the local characters?
Thanks.

Write the string in labview
Hi everyone!
Now I'm doing that translate the string from analog value in real-time
ex) If, Value<30 = A , 30<Value<60 = B , 60<Value<100 = C
And then, I can show the string in real-time now
So, I want to write down that string one by one, when I push some botton!
please give me some advice for me !

After PC restart NI-MAX starts with driver problem
Hi to All,
I have strange problem with USB-232 driver. On Win 10 I insert USB-232 and driver installs ok . Everything works fine and communication is ok.
After I restart PC in device manager driver is ok, but in NI-MAX it isn't work. If I try to communicate thru 232 it goes to unknown error. When I remove the device and delete driver, I insert device again and it works until next reboot . Any suggestions?
Could it be the windows security problem. I'm not an administrator of the machine.

Graphe LabVIEW
Bonjour,
Comme sur la photo ci-joint, j'ai superposé deux graphes XY et quand je clique sur Zoom au niveau de la 1e ou 2e, les echelles X ne sont plus alignés.
Quelqu'un aurait une solution , pour quand je clique sur Zoom, le graphique reste fixe.

FPGA rational resampler
Hi!
Im working on a project and I use a compactrio 9040 with 4 x NI 9224 modules. I wish to resample data from the modules from 1000 S/s to 20 S/s using the rational resampler on the fpga. But it does not work as I want, it seems like my output data is rather ~22 S/s.
My question is if I use the resampler and FIFO incorrect somehow?
Currently I wait for the outputvalid signal before sending it into the FIFO, is that the correct way to deal with?
Please see the attachments.
Best regards
Martin

Kaysight Instrument drivers
HI,
Does any one have any Labview Instrument drivers for Keysight 8164B LMS? The earlier 8164A dll doesnt work anymore as it is a 32-bit wrapper implementation.
I am looking to perform an IL-PDL sweep using a TLS inserted into Keysight 8164B LMS, a Polarimeter and a Power detector.
The IL and PDL involves the triggering mechanism thats where i am totally lost and dont have sequence of SCPI commands to run.
Thanks for your hep..

Labview Code Module used in NI TestStand: Memory leakage
hello, I have the following problem and cannot find a workaround:
- In testStand I call a SubSequence as new execution, by passing an array [0..7] of Waveforms (Labview Analog Waveform Type) as reference.
- Within the called Subsequence I call a LabVIEW Code Module for reversing each passed Waveform (each array[0..7] element) using the "Reverse 1D Array". (see attached screenshots with Block Diagram and Parameters as used in the testStand code module step).
- The VI execution mode is set to “Shared Clone Reentrant” since I need to use it in 5 parallel testStand Executions.
- The VI input and output parameters refer to the same TS Sequence Parameter (but I think it is normal since I need to reverse in place the same array). See the attached picture as reference.
- The labview code module works fine (it does what I expect) but…I experience a MEMORY LEAKAGE after a while.
Is anybody able to help me?
thank you in advance!

LabVIEW Merge and Git
We currently have Git setup to use LV Merge whenever a merge action is needed; however, when Git creates the merge files it places it at the root of the repository. When LV Merge opens those files the dependences become in relation to the merge files and not the original file. Has anyone experienced this or found a workaround?

Possibility to run Radiated Emissions Testing with LabVIEW?
Hello everyone.
Is it possible to setup/run a DO-160, section 21 Radiated Emissions scan with LabVIEW? I know there is a spectrum analyzer view in LabVIEW, and I am wondering if the data can be captured by having LabVIEW control VBW, RBW, and the sweep rates and record the data. We are looking at the compactDAQ chassis with various voltage/current/etc... modules. We have a spectrum analyzer, the Tektronix RSA306B (USB), which needs a little work to connect to LabVIEW but it seems possible.
Any recommendations to lead me in the right direction would be very helpful.
Thanks.

Creacion de Archivos .txt
Saludos
Tengo un problema con mi código de LabVIEW, cree un código de adquisición de datos para una compaq RIO 9038 en el cual quiero obtener información de un banco de pruebas, al igual cree un subVI que tabula la información guardada durante un tiempo de medición y lo almacena en un archivo .txt, el problema aquí es, guarde mi Main Vi y mu SubVi en la memoria del chasis de la CompaqRIO 9038, peor el SubVi no crea el archivo .txt o no aparece en mi PC en donde le asigne.
Mi pregunta es si el SubVi crea archivos dentro de la memoria de la CompaqRIO? y si hay alguna manera para que el SubVi cree los archivos en mi PC?
Agradezco su Respuesta

TCA9548A Multiple Addresses Issue
Hey guys. I've only used labview for about 2 months so please bear with me if it is something simple I overlooked. I'm trying to get 8 Sensiron SHTW2 through a TCA9548A multiplexer using the I2C bus on a NI USB-8452. All the sensors have the same address (0x70) I'm just cycling through the multiplexer addresses (Decimal values: 112-119 to indicate sensor 0-7) I've attached the code for reading the sensor/multiplexer. The data screenshots are from my Main VI.
When I have a sensor isolated without the multiplexer and remove the section of code labeled "Address Multiplexer" the code works fine.
When I attach the multiplexer and try to address individual sensors I start getting the same data for each sensor repeated every second.
Thanks in advance! These forums have helped me a ton these last two months.
