Documentation of Labview Vis

When distributing application programs created in Labview we have to provide a complete documentation package.
We used to print most of the Vis on paper which is very time consuming and pretty hard to maintain in case of a software upgrade.
I am looking for a tool to view the Labview source just like the development system but the user can not change or run the code.
I found the Labview player which looks like to have this functionality.
Is Labiew player for Labview7.1 available?
Has anybody some idea how to handle this in an easy way?

I'm looking for a package or library to document VIs of an application in a manner like the LV Help. This could be a HTML Help (chm-file) or a website (html-files).
I know that I can programmatically print to HTML with settings from application: printing and vi: printing. This will give a single HTML file for each VI - I don't like the appended version - with all the graphics files. This file isn't formated in any way so any postprocessing must be done; like referencing to a css, active links to callers and callees. For the windows platform compiling to chm with the HTML Help workshop would be nice, using the folder structure for the structure of the TOC.
I tried to find out what the nirsc_html_help_common package available from OpenG does but the description seems to be really empty. I tried to install it but didn't get it to work. This is another thing I have to solve.
I was pointed to the Documentation Generator from VI Engineering. This one seem to be either over featured or too expensive.
The online help is refering to third party products but I need something to create just the input for the HTML Help Workshop.
Can someone give me any hints about that?

Find names of all open windows including other applications besides LabView VIs

Hi All, I have researched this subject, i.e., to find names of all open windows including other applications besides LabView VIs, but found no solution. Could someone suggest a solution to this? Thanks.

Hi,
Certainly! The Windows API Function Utilities (32-bit) for LabVIEW includes set of LabVIEW libraries (llb) with VIs that make calls to the Windows Application Programming Interface (API) for managing and controlling windows (minimize, maximize, move, resize, rename, close, and so on) including task list with names of windows application running. The Readme.doc contains information on running these VIs.
Attached below is a zipped file with a VI that list the names of all opened windows.

Labview VIs for HP 35670A

The link to the labview VIs for the HP 35670A is no longer valid and the search for the same returns nothing. Does anyone have the Labview VIs for that instrument?
The last post was back in 2004(see below)
The instrument driver for the HP 35670A is only
supported under LabVIEW 6 and 7. You should upgrade to the latest
version of LabVIEW in order to use the HP 35670A driver or any of the
newer drivers that we release in the future.
The instrument
driver for the HP 35670A can be found on our web site at
http://zone.ni.com/idnet97.nsf/9b2b33e1993d877786256436006ec498/61f1c707c2f10906862568ab005fb9ff?Ope...
Solved!

Why don't you go to the Instrument Driver Network? I don't know what kind of search you did but the driver is certainly still available and can be found by using the search option there.

How to read and write data from Excel to TestStand without using LabVIEW VIs

Hi,
How can I read in columns of data from Excel into a TestStand array and write columns of data to Excel from TestStand without using LabVIEW VIs?
I don't think the Property Loader custom step type in TestStand will work because the data I would like to read in from Excel is in a column that is thousands of rows long and the data has to be in the proper format to use the Property Loader to load in an array from Excel.
Thanks for your help.

That example does not use LabVIEW and it does about 40% of what you need to do by calling Excel through ActiveX. If you don't know how to use Excel through ActiveX then you'll need to brush up on that.

Communicating USB using Labview VISA

I have a USB RAW device that I am trying to communicate with using labview VISA. I have had success with setting up the driver and I am able to get information from the device such as serial number, etc. When I try to use the VISA read and write commands, I have no success getting the information I want. The commands are simple: R SP<CR><LF> is a read set point command. The only thing I do get back for every command I try, is a 2 byte message "01 60"hex.
If you have any suggestions, I would appreciate it, thanks!

Hello Chris, I do not receive any errors and yes, I am including the termination characters in the string.
Here is what I get when I use a USB port monitor when I send out this string.

Calling labview VIs from python in Linux

Hello.
I've spent some time searching for this but I haven't found exactly what I was hoping for.
I'm involved in a project that we're starting now and it involves creating a complex software architecture in order to control a robot. This software will need to perform multiple tasks such as interfacing with hardware (which LabView is perfect for) as well as planning and high performance image processing (which LabView isn't as great for).
I was hoping to be able to use a scripting language like python to manage high level stuff (planning, behavior, etc) by calling "subroutines" in other languages such as C++ for the high performance stuff and LabView VIs for the hardware interfacing. I would also like this to run on Linux.
I've found a lot of suggestions on how to call Python scripts from within LabView but this is not what I want. I want exactly the opposite, invoke VIs from Python. I found some information on how to do this on Windows (http://zone.ni.com/devzone/cda/tut/p/id/5719) but this article seems to assume that Windows is being used.
Does anybody have an idea on how to do this?

Unfortunately that's not an option. This is an interdisciplinary school project involving students from engineering (mechanical, electrical and more), computer science and more fields. Some of these students have gotten used to using Labview and this is the main reason I'm trying to accomplish this. I want to have the higher level architecture done in a scripting language such as python which will enable us to create modules in various different environments such as C++ for tasks requiring high performance (image processing for example), Labview for tasks that the people used to using that and even something running on the GPU if there's use for that. Python would make it easy to glue all these components together while maintaining an environment that would make it very easy to configure the whole software system in different ways.
I'd also prefer that this all run on Linux.
The more I look for this the more hopeless I get I'll find anything which is very frustrating. It's a bit hard to believe that Labview doesn't have "python bindings" for running the VIs from within python :-(

Logging data in a file using Labview VIs vs. Mathscript functions.

Hello,
I'm working on a data logger at 200 Hz frequency. I wanted to log the data to a file after eace sample received. When I used (fopen,fprintf,....) on Mathscript, the Labview started to log the data at a slower rate. I then used the Labview file VIs and it is working fine up till now.
My questions are as follows:
1- Are the file functions in the Mathscript slower than the Labview VIs ?
2- Is saving the data to a file after each sample is received a good idea or is there a better idea ? I just don't want to keep the data in the memory and after all the data is logged, I flush them to a file ... because, it seems that the PC will run out of memory.
Thank you,
Walid

My questions are as follows:

Yes. That's because you're going through another layer of software. Why were you trying to use MathScript to log data to file in the first place? Are you a Matlab "aficionado"?
2- Is saving the data to a file after each sample is received a good idea or is there a better idea ? I just don't want to keep the data in the memory and after all the data is logged, I flush them to a file ... because, it seems that the PC will run out of memory.
It doesn't make sense to save data after each sample. File I/O is an expensive operation in terms of time, and you have the operating system to deal with, so while you may be able to keep up the rate for some time, eventually it will be thrown off. You can do as suggested which is to wait until you have a certain amount and then write that to file, or you can set up a producer-consumer or master-slave architecture. Let one process/loop collect the data and put into a buffer, like a queue, and the other process/loop can stream it to disk at a more reasonable rate. You just have to make sure the buffer is large enough so that if the file I/O gets hung up you won't reach the buffer's limit.

Using HTTPS and SSH from LabVIEW VIs

I am currently using custom VIs, built over the TCP/IP LabVIEW VIs, to access to a distant machine with the TELNET protocol, and to access a HTTP server with the HTTP protocol.
In a near future, I will have to use more secure protocols such as SSH and HTTPS, that my VIs will no longer support.
Does the NI Internet toolkit support SSH and HTTPS?
And if it doesn't, what are the solutions?
Using PuTTY with a command line for SSH is suggested by NI and I have already tested this successfully.
Have someone other solutions and an idea for using HTTPS?
I'm currently using LV 6.1.

Where can I find example LabVIEW VIs for the NI-USRP?

There are several sources of example LabVIEW VIs for the NI USRP:
We have established a NI Community "NI USRP Example LabVIEW VIs" where you can find example VIs from us (NI) and the community.
The NI-USRP driver installs a variety of example VIs to the to the following folder on your PC:
<LabVIEW Installation path>\examples\instr\niUSRP
where you should replace <LabVIEW Installation path> with the root folder of your local LabVIEW installation. For instance, my Windows 7 32-bit PC here has LabVIEW 2011 installed and the examples can be found here: C:\Program Files\National Instruments\LabVIEW 2011\examples\instr\niUSRP
I've installed the NI-USRP driver, but I can't seem to find the new examples in the LabVIEW Example Finder. Where are the example LabVIEW VIs installed by the NI-USRP driver?
Although the NI-USRP driver does indeed install examples, the current NI-USRP 1.1 release does not update the LabVIEW Example Finder with entries for these examples. To find the examples, you can navigate the Windows Start Menu to the following location:
Start Menu\Programs\National Instruments\NI-USRP\Examples
This Start Menu entry includes several Shortcuts that point to folders that are the home to example VIs.

Hello,
It looks like Agilent/HP makes the 8990A, but I was not able to find a driver for it that we or Agilent has written for this device.
Since I am not familiar with the 8990A, I cannot recommend which drivers might be similar, but you are pointed in the right direction. Agilent themselves might know more about which models use similar command sets so that you can modify a driver easily.
Hope this helps.

How to use Modal Parameter Extraction Labview VIs

I can't install Modal Parameter Extraction Labview VIs
http://zone.ni.com/devzone/cda/epd/p/id/6121
The installer says "NI Labview System Identification Toolkit 4.0 or 2009 must be installed before you can install NI Modal
Parameters Identification 1.1"
under Labview 2010(+the
LabVIEW Advanced Signal Processing Toolkit and LabVIEW System
Identification Toolkit).
Should I delete Labview 2010 and reinstall 2009??

Hi KCMTM,
My name is Yusuke Minami, Applications Engineer, NI Japan.
I'm so sorry, but the "Modal Parameter Extraction Labview VIs" is not supported by LabVIEW 2010.
Since it will unlikely be updated for 2010, we have to ask you to install LabVIEW 2009 with the LabVIEW Advanced Signal Processing Toolkit and LabVIEW System Identification Toolkit in order to use the package.
Although I cannot guarantee, but I'll send an update request to the R&D.
I deeply apologize for the inconvenience.

Some errors when calling LabVIEW VIs Interactively from DIAdem

Hi! I'm having some trouble using the "Calling LabVIEW VIs Interactively from DIAdem" found on:
http://zone.ni.com/devzone/conceptd.nsf/webmain/1A98AB48E35D913086256E23004E6A22
Following the troubleshooting section didn't resolve the issue. I
recompiled and built the exe (DIAdemLabVIEW.exe) for version 7.1.1,
which I am developing on. But still I got the same error message, after
a waiting for about a minute, on a diadem popup window:
Error in <MenuAdd...ctDo.vbs (row:1, column: 1)
Error in <addmenuentry.vbs (row:14, column: 3)
ActiveX component can't create object.: 'DIAdemLabWIEV.Application'
Using the llb's and exe's that was included with the installer worked
flawless, with the exception that LV 7.1.1 vi's didn't appear on the
popup window(DIAdemLabWiev.vi). So I tried to recompile and build for
the 7.1.1, with this result.
I'd be very grateful for fixes or solutions for this problem!

Roger Isaksson

Brad, thanks for the reply! Below is my (correct?) modification of your script. Have I got it right?
Dim lvapp, vi, viPath, paramName(1), paramVal(1)
Set lvapp = CreateObject("LabVIEW.Application")
viPath = "C:\TEMP\Test.exe"
Set vi = lvapp.GetVIReference(viPath)
vi.FPWinOpen = True
paramName(0) = "In Name"
paramVal(0) = "In Value"
paramName(1) = "Ut Name"
Call vi.Call(paramName, paramVal)
Call lvapp.Quit()
MsgBox "Parameter1 Value = " & paramVal(1)
I am not sure about the format of the <paramName(0) = "In Name">.
The control name is "In" and is a I32, the name for the indicator is
"Ut" and has the same storage type as the control.
Running the script gives an error in line 4, that is the <Set vi =
lvapp.GetVIReference(viPath)>. I'll attach the exe and the error
message.
I have another question regarding the relatively large amount of RAM
that diadem uses for export from my labview application to diadem. More
than 10 times the size of the data is required for exporting to diadem.
Since our application use relatively large files, actually up to
several GB's, this soon becomes problematic. See the attached picture
of the memory usage after exporting a 10MB segment (contains 42
channels of measurement data). Your help in these matters would be
appreciated!

Metrics on Labview VIs

Does anyone have a VI or utility that will collect lines of code equivalents
for Labview VIs? Or any other similar SW metric for measuring complexity
of LV code?

You do not say what version you have.
There is a tool in the Professional Dev System for lv5.1
that does VI metrics. It measures quite a few parameters of your VIS
If you have PDS Version 5.1 look under the Project menu and select
VI Metrics.
If not you may want to consider upgrading or contacting NI sales.

AlazarTech ATS460 LabVIEW VIs

Has anybody programmed the ATS460 Digitizer card from AlazarTech using the LabVIEW VIs supplied by this company?? I have a few questions and will appreciate if someone who has worked on it can help me out. Thanks!

I have not personally worked with the AlazarTech VIs, but you might as well go ahead and ask the questions. Is it about the general functionality, or something specific that AlazarTech support might be able to help you out with? In any case post your questions and as much info as you can about the VIs and your application and we will do our best to help you out!

Call LabVIEW VIs from MATLAB

Does anybody know of a simple way to call LabVIEW VIs from within a MATLAB m-file? I would like to be able to write VIs in LabVIEW and then script them (for stochastic analysis, etc.), and think MATLAB would be an awfully convenient way to do this (also useful for data analysis, etc.). I have looked at LuaVIEW, but it appears to have been largely abandoned.
