Is it possible to test a LabVIEW application

I'm currently developping a LabVIEW application. To ensure functionnaliti, quality... I would like to automate test. But I would like to test the overall application. And this kind of test requiers a user that read dialog, click on button of dialog box, do some actions... Does TestStand allow us to repeat theses operation?
TestStand is new to me. I saw some demonstration in some LabVIEW seminar. But I understood that it was mainly built for testing VI that has inputs and outputs... We specify parameters and we have an average of response to compare to. am I mistaken?

Are you looking for a tool to validate an application? Winrunner and Rational have packages for GUI testing. TestStand is not for testing VIs. It is a test manager. It uses VIs, DLLs, etc. to perform tests, manage the results, create reports, and log data. It could replace all of your LabVIEW dialogs.

Is it possible to take a labview application and compile it to run on an embedded processor?

Hi
I was wondering if anybody out there knows if it is possible to take a labVIEW application and compile it to run on an embedded processor (e.g. ARM7)?
If so does anybody know what the required capability of the target processor is (i.e. RAM, ROM etc.) and what tools I need.
Many thanks
Ash

Ash,
There is also another option for processors like the ARM7. You can load a PDA OS on it and use the LabVIEW PDA toolkit. The LabVIEW PDA toolkit is MUCH easier to use and is quite a bit less expensive. You will have the problem of getting the OS correctly configured, but in the long run, it may still be cheaper and easier. I use it quite a bit with my Dell Axim X51v which has this processor and Windows Mobile 5. There are still problems to work out, but not nearly what there are with LabVIEW Embedded.
If you want to go the LabVIEW Embedded route and you need some help, let us know on this forum. There are several of us that have experience and can help to guide you.
Hope that this helps,

Unfortunately it is not as simple
as throwing together the application builder code of all platforms into
one piece of software. Some things need certain support from the
underlying platform too and that would mean NI would have to provide
emulation/simulation or whatever of certain platform features to be
able to build for instance a Linux executable on a non-Linux system.

Is it possible to invoke other software applications in labview?

Is it possible to invoke other software applications in labview? I would like to upload my files processed in Labview to my web based database. I have no basis of FTP and SQL. Providing that I have no Internet Database Toolkit installed in my computer. So, is it possible to "call" the software in Labview, just like calling a function or sub VI?

Hello kaykeat,
It is definitely possible to call other applications inside LabVIEW. Please see the links below for more help on the most common ways to call external programs.
If the code is a shared library:

Is it possible to hide the LabView Data folder through the labview application?

I really want to get rid of the LabView Data folder in the My Documents Folder that is created when the built labview application is run. Since it does not seem to be possible to remove or relocate it, i was wondering whether it is possible to at least hide it - but I want it to be done automatically, i.e. through the program itself when it is executed.
Thanks
Tim, Van

Hi,
you cannot delete the "LabVIEW Data" Folder since your application is active!
It's possible that you change the attribute (hide) for the whole folder before you start the compile process!
If you want to do this automatically, you should ask microsoft which dll is relevant for this scope!

LabView Application program crashses randomly

Hi,
I have developed an application for a monochromator system using LabView 2012 (32-bit version) as my programming language.
My application performs calibrated scan using the Calibrated Photodiode from 300 nm to 1100 nm and then perform Device Under Test (DUT) scan from 300nm to 1100nm at an interval for 5nm.
My application crashses randomly when inside a for loop that goes from 300 to 1100nm at an interval of 5nm, whether it is performing a Cal Scan or DUT scan.
The one thing that is consistent is that it crashes whenever LabView executes my supplier’s .NET DLL/ function call. Once the application program goes into the monochromator function call, it does not give LabView the control back. The application is stuck inside the function call.
On Good days I am able to scan up to 30 parts with no crashing, while some days it can barely scan 5 parts. It is very inconsistent.
I am not sure if anybody have seen any problems using dll to interface with Labview 2012.
I have attached an image of problem I am encountering, where the LabView application is stuck in the DLL and it does not give control back to LabView.
I would appreciate any assistance on this subject.
Thank you,
Nirav

Can LabVIEW application properties (e.g. Callees) be accessed from visual studio (C++)?

Hello folks,
Can LabVIEW application properties such as "Callees" be accessed from C++?
Best Regards,

You can enable the ActiveX interface in LabVIEW and use its Automation server interface. This interface exports a subset of the VI Server interface to ActiveX. A subset becauseof security concerns. You do not want an arbitrary ActiveX client (possibly remotely) to look at your entire project and change about anything they like.

DECODING MAIL FROM WEB SERVER IN PLAIN TEXT FORMAT(THE MAIL BEING SENT BY LABVIEW APPLICATION)

Hi All
I have a labview application that send mail every hour automatically.
But actually the mail has to be decoded from the web server(by another application).But now when that application decode the data in the mail(that is send by labview application)its getting some funny characters inside that can not be detected by the decoding application
(When open the mail no problem.)But actually our goal is to decode the mail from the web server.
Why the extra characters are appearing when decoding from the server?Is it because of the HTML format?
Is there option to send the mail in plain text format(not like attachment)?
In outlook we can change the setting (tools->options->send->mail sending format->....here we can set as HTML format/Plain Text format)
Like that at the sending time can i chenge the sending option as plain text format in my labview application?
Thanks...

Then it sounds to me like this other application is not decoding the attachment correctly, especially if you looked at the attachment yourself after you received it and verified it's correct.
No, no, smercurio. This is charcter encoding here. In older versions of LabVIEW you could specify what character encoding to use when sending an email through the SMTP VIs. But that gave problems since people in certain locales used certain characters that where not transfered right when the wrong encoding was specified, and that encoding stuff is not understood by most people at all, so the wrong selected encoding was rather the rule than the exception. In newer versions of LabVIEW do the SMTP VIs handle the encoding automatically based on the currently used locale on the system.
This change is documented in the Upgrade Notes of LabVIEW and probably happened around LabVIEW 7.1 or 8.0.
A decent mail client will recognize the encoding and convert it back to whatever is necessary before presenting it to the user. The OPs posters server application obviously isn't a smart mail client but probably just some crude text file parser that has no notion of proper mail character encoding and how to deal with it.
I would suppose that there is a chance to dig into the SMTP VIs itself and try to manipulate or disable that encoding altogether in there but that may open a whole can of worms somewhere else. The proper way would be to process the incoming mail by a character encoding aware mail client before passing it to the text parser. On Unix setting up something like this would be fairly trivial.

How do I embed bitmaps into a built (.exe) LabVIEW application?

I am trying to embedd bitmap images (icons) into the exe file of a built LabVIEW application. I tried it, and got them in a "data" folder. I want everything in the .exe file, you know, just like C/C++ or just about any other programming language.
If anyone has any tips, I would be grateful.
I know about embedding the images in the controls, but that is not my goal. I need images as files to be embedded, somehow, into the .exe. The reason is I am using the picture control to read the images, but they are static once they are read. If it is possible for the picture controls to somehow retrieve the images from some other source, that would work also.
Otherwise, if someone knows how to dynamicall
y embed bitmap or other images into buttons in an array, that would be useful as well.
Thanks

Actually, many C and C++ programs, like LV itself have folders of data
that aren't linked into their code. But, if that is what you are
looking for, one pretty easy way is to load the images into memory and
place them into a 2D array of data, a string etc. Make an array of
these and make the value default. At runtime, you can now skip the file
I/O, or you can write the data to a temporary on launch and read them
back whenever you like.

DataSocket Server will not start when the Launch DS Server if Local URL.VI is bundled into a LabVIEW application.

I want to run a LabVIEW application on several machines remotely that do not have LabVIEW installed (licensing issues). Hence I have built a LabVIEW executable with the RunTime Engine to install on all of these remote machines.
The VI has a bi-directional link, using Datasockets, to a machine with DAQ and Image acquisition functions. It primarily receives data items, but also the capability to change data items so it needs to run the "Launch DS Server if Local URL.VI" in order to publish data to the DataSocket server.
When I run the pre-built VI on a machine that has LabVIEW Developers Edition installed, everything works fine - ie.
the DataSocket server starts on the remote machine. However when I build the *.exe application and run it on a machine with and without LabVIEW Developers Edition installed the VI successfully subscribes to the DAQ and Image Acquisiton machine, but it does not start its own connection to the Data Socket server, and hence does not publish the data that the DAQ machine needs to suscribe to. IT seems that the Launch DS Server if Local URL.VI is bypassed? I have fiddled around with the Build settings but to no avail.
In short, how do I get the DataSocket Server to run in a LabVIEW executable? Is it indeed possible? Any advice would be welcomed.
When distributing a Labview Application (*.exe) with Data Socket Server Publish functionality, the DataSocket server does not start and hence no data can be sent by the Remote PC to the Server. The VI successfully retrieves data from the DS Server. I have used the "Launch DS Server if Local URL.vi" in the ditributed application but for some r
eason this VI is not executed when I run the executable. How can you force the DataSocket Server to run with executable LabVIEW applications?

Ryan,
How to add Datasocket Server Control.vi?
Source Files only show Project Files.
So, I added Datasocket Server Control.vi file to the project first.
Then I added it to Always Included < Source Files < Application Properties (Build Executable).
Last, I built the Executable, but it didn't work.
Can you help me.
Thank you.

Is it possible to open a LabView VI in a Webbrowser or an HTML-File?

I want to know if it is possible to run a LABVIEW vi (Version 7.0) in a Webbrowser or a HTML-File.
Are there Browser Plugins or other possibilities to create Self - running VI`s ?

LV from Version 6.1 up has the capabilities to support remote panels via a WEB Browser: See the tutorials under
http://zone.ni.com/devzone/learningcenter.nsf/03f7c60f17aad210862567a90054a26c/2ad405a06ebed71586256c4e00621c73?OpenDocument
http://zone.ni.com/devzone/conceptd.nsf/webmain/8BC90A5F744A482886256BA000681713?opendocument
All you need is the LV Runtime Engine installed on the machine where you want to view the running vi.
Additionally you can create standalone running vi's with the LV Application Builder which creates LV executables. These executables are also compatible with the remote panel functionality.

Stephan A.
