Labview 2011 web server

I have been doing some development of web services using LV2010 with no real problems. I just installed LV 2011SP1 on my machine, and now I can't get the web application server to operate. When I go to the configuration page I see the application server has nothing checked (attached picture) and also options for 32 and 64 bit, which didn't used to be there when I was running LV2010. When I put in a port number and check "enabled" and then select Apply, nothing seems to happen. When I select either 32 or 64 bit, I get a pop up message error (attached picture). Is there something else I need to do to get the web application server working after installing LV2011?

I've uninstalled everything I could find that was related to National Instruments, and then reinstalled LabVIEW 2011. Now when I go to the server configuration page, it just looks like it's loading, but never actually finishes and shows the page (see attached)

Running the G server and labview web server as a stand-alone serve

Hello,
Now I am running the G web server from the Internet toolkit cooprating with the Labview default web server because I need the server to handle both GCI reguests and the requests of the remote panel.
Now I have a question. Is there any way to make these two servers as stand-alone applications and also make it to be window service ( I think if I could make them the stand-alone applications, making them to be window services would be easy)? I just want the web server to be a stand-alone application without installing the Labview (just installing the run-time engine) on one machine. Could this be done? Thank you very much.
Best Regards,
Benjamin Chu

Hello Benjamin,
for running a LabVIEW application as Windows Service is here a tutorial.
I formerly tried to get the G web Server into an application and I know there were some dynamic VIs loaded by the HTTP Server Control.vi and some SubVIs. I never tried this seriously enough to get it running.
You need at least to put the VIs vi.lib\addons\internet\http\http0.llb\HTTP Server, vi.lib\addons\internet\http\http0.llb\srvr_%02d.vi (%02d is part of a format into string with a for loop index), HTTP Load Configuration Files.vi as dynamic VIs into your build definition.
Running the G Web Server and looking at the VI hierarchy is not for help because for some reasons the G Web Server VIs will not show up in the VI hierarchy window.

Using LabVIEW Web Server in RT for other web applications

I'm looking to find out whether or not I can host other web page technologies (Java Scripts for example) on web pages hosted on a LabVIEW RT target. I'd like to be able to post a configuration or status page on the web server as well as the standard VI Front panel page.
Thanks,
Jason

Hello,
LabVIEW RT Web Server is not meant to be used for other things different from LabVIEW VIs. This feature is not supported.

G web server monitoring

Hello all,
I am running a web site that is using the LabView G Web server to deliver various report results. The entire site and all reports are written in LabView (7.1.1). What I would like to know is anyone out there using any web server monitoring software for the G Web server? I would like something that can not only notify me if the web server goes down, but could provide usage stats etc. There is an issue in some of the reports that use Matlab code inside of the LabView, that will occasionally crash all of LabView with a memory location error. Since all of labview crashes I cannot use a labview solution for monitoring.
Any suggestions or recomendations would be appreciated.
thanks

Hi,
That sounds good, except for the part about LabVIEW crashing Did anyone ever look into the root cause of that error? It's great to have the automated notification process in place, but perhaps it's worth looking into the origin of the crash itself. If you have more information about this, I can try to help you with that! You can also check out the knowledgebase for articles related to LabVIEW and Matlab and any problems using them. You noted that the issue was with "some of the reports that use Matlab code inside of the LabView" - I don't think we ever attacked that aspect of it directly, outside of the exe suggestion. Anyway, is it possible to implement the necessary features in LabVIEW exclusively? If you can describe the nature of the code which is not LabVIEW native, perhaps I can direct you to a pure LabVIEW implementation which avoids the problem.
Thanks and have a great weekend!

Running a headless VI in Linux through web server

I need to "embed" a VI in a headless Linux device running labview. Once the VI is running on the headless device I need to be able to connect to the VI through LabVIEW's web server.
I have the web server and page all configured correctly on the device (meaning, I've been able to connect to the VI through a browser and operate it as desired). The trick is, how do I launch labview and the VI on a headless linux device? Ideally, I'd SSH into the device and launch the VI and labview through a shell script, logout of the SSH session; then I'd connect to the VI through the a browser...
Advice?

Figured out a way to do this remotely using SSH. Create a shell script with the following contents
export XAUTHORITY=/home/<your username>/.Xauthority
export DISPLAY=':0'
nohup labview <path>/<your.vi> &
Log in with SSH and run the above script. This launches LabVIEW in the background and allows you to exit the session without killing the VI. Once running, you can connect to the VI throught the web server using the standard method.

How to create web applications with the LabVIEW web server

Wonderful Forum,
I've noticed that sometimes it can be tricky for LabVIEW users to learn how to create their own custom web clients using the LabVIEW web server. I created a LabVIEW web development community group and wrote some tutorials to teach the basics of creating web clients using HTML, Javascript, and AJAX. The idea is that LabVIEW users without any web background can quickly look at some tutorials and examples to get started on their own projects.

Hi Joey,
A great idea! I recently presented at a local user group meeting about my WebSockets API (see the links in my signature). I've uploaded the presentation and the demo code I gave to our UG here.
I think the barrier to entry is with needing to know the web languages (e.g. html/css/js) as well as writing your LabVIEW code. I have joined the group and look forward to seeing some interesting content on there! Certainly some demos of using AJAX to make requests to Web Services and do something with the data (e.g. display on a graph) would be a good place to start.

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.

Web server log files under LabVIEW RT

Hello,
Is there any log files for the web server under LabVIEW RT running on a PXI? The log file checkbox is disable in the target options.
Also, is there a way to find out if the web server is running on the target?
I'm asking the question because I can't access anymore a remote panel (and even the root of the web server) on my PXI. I reinstall everything and I still have the issue. I'm pretty sure that IT changes some network settings but they say no. I need to validate that everything is working on my side before before taking further action.
Thanks,
Patrick

Hi Patrick,
I would suggest having the log file checkbox enabled in the target options. That should show if errors are occurring while it is running. Are you running remote front panels and web services, or just remote front panels?
Can you provide a picture of all the software you have installed on your PXI? You should be able to find this in MAX under the PXI in Remote Systems.

LabVIEW 2013 Web Service works on debug server but not on application server

I have made a LabVIEW web service, that needs to get 2 inputs from the user through html request, and one input from a running VI. For this communication I have used a notifier to transfer data between the VI and the webservice method. This works perfectly fine on the debug server, but doesn't work when I deploy the web service on the Application Web Server. As shown in the attached snippets, I use a FGV to transfer the reference of the Notifier from the VI to the web service method. This is the same method that is described in this link.
Is this method correct? Or am I missing something?

I can't find the right link but....
There is something I ran across a while ago about how to enable the correct server port in you application. The VI Server debug port gets enabled with debugging enabled but, you need to specify your services port in the <MyApp>.ini file.
I'll sit back and watch the masters now

How to configure LabVIEW web server to allow viewing and accessing the content of a folders

I have added the following html line to the body of the html file generated by the LabVIEW Web Publishing Tool:
<a href="MyFolder" target="_blank">My Folder Content</a>
I expect the link labeled "My Folder Content" to open a new browser window displaying the content of "Myfolder" which is located inside the LabVIEW webserver root folder. I got an error instead. If I substitute "Myfolder" with a filename, the browser will display the file just fine.
Can someone provide me with some hints on configuring the web server for this purpose?

Hola Hector
Estoy trabajando con tu caso y se me ha hecho bastante interesante.
Solo te quiero preguntar... que version de Internet Explorer tienes?
Utilizas algun otro web server ? ( Mozilla tiene este problema me parece)
Segui los pasos que mencionas con Internet Explorer 6
y pude abrir la carpeta sin problemas.
Te pido por favor que me contestes estos datos para darte una solucion muy especifica.
lamentablemente tengas que hacer referencia directa ( todo el path) a los archivos del folder para accesar a ellos si tu explorador no lo permite.
Lo unico que puedo confirmarte es que parece no ser un problema de National Instruments.
sin embargo si me das mas informacion podemos descartar cualquiera de las conclusiones a las que he llegado.
Espero tu respuesta
Saludos

Error 43 when accessing LabVIEW 2009 write/read file functions through the web server functionality

Is there any way around to avoid Error 43, "Operation cancelled by user" when using Web server?
I am using the example VI:s RemotePanelMethods-Server.vi and RemotePanelMethods-Client.vi to acces the MainGUI.vi from my workstation to a lab computer. * LabVIEW 2009 is installed in both machines.
* MainGUI.vi is wired to the VI access list in the Server VI but it also contains a hierarchy below that isn't, is this a problem?
* Several functions in MainGUI calls file read and write operations
The problem ocurrs when file read/write operations with no preselected path are selected through the Client. The traditional popup window requesting the file to read or write is never seen in the Client, but only the Error 43.
Thanks in advance

Difference entre G web server et LabVIEW web server

Salut,
je voudrais savoir quelle est la difference entre le G Web server et LabVIEW web Server et quelles sont les avantages de chcun d'eux.
Merci.

Bonjour rose2009,
Labview web server est le serveur web alors que le G server permet d'executer des script CGI. Il faut se rappeller que labview web server ne permet pas de faire des entrées/sorties, les CGI VI permet de recevoir les entrées ou les requetes pour renvoyer les données.
Cordialement,
Hi rose2009
Labview web server is the web server until G server allow to execute CGI script. LabVIEW does not work with standard HTTP input and output, a CGI VI receives the standard input data as a string when it receives request and sends data that it generates as a string.

Security Issues of Labview Web Server?

Hi All,
How secure is the web server for Labview? Is anyone aware of any one
successfully hacking the systems?
I would assume that it could be possible to gain full control of the
machine running Labview as Labview can read/write data to drives etc.
Just interested as we will be running labview servers on open network
not protected by a firewall etc.
Any comments?
Regards
Wayne Peacock

I have found that a LabVIEW application running the Web Server can be crashed from any machine that has access to it. The Browser Access List denial of an IP address will not prevent this crash.
I have reported the details and National Instruments has confirmed the report and responded with this: "Crashing LabVIEW Through the G Web Server Using TCP VIs"
http://digital.ni.com/public.nsf/websearch/4C3F86E655E5389886256BA00064B22F?OpenDocument. It turns out that this crash will only occur if the web server logging is enabled.
Aborting a server is generally categorized as a Denial of Service (DOS) attack. In this case, it is the LabVIEW application itself that aborts, web server and all. This can be more serious than the usual DOS if the application is perf
orming some other important activity by running VIs. They would unexpectedly abort along with the rest of LabVIEW.
This attack does not enable reading or writing drives, or otherwise controlling the host machine, the vulnerabilities that you asked about. I have even tried to trick the server into getting pages outside of its root directory without success.
If you are running a LabVIEW Web Server, you should certainly disable web server logging. If you could not tolerate an unexpected abort in some LabVIEW VIs that you are running and want to be even safer, I recommend that you do not run them in the same LabVIEW application that is running the LabVIEW Web Server. The principle here is compartmentalization.
On one hand, the small number of deployed servers, relative to other more numerous and attractive targets, has not attracted undesired attention. So you're pretty safe now. On the other hand, LabVIEW is growing and moving to the Internet, and LabVIEW systems control machin
es and chemical processes, not merely data and dollars. Think about the risks as well as the convenience of using the web.

Losing smart camera connection when using web server on NI1762 smart camera

Hi
I am using 2 smart cameras ( old NI1762 and the new NI1772) with Vision builder 2011 .
I am trying to find a way to retrieve data and image to a Visual Basic 6 application. i could not find an elegant way to do it , so instead , i am sending TCP command to the smart camera as an input and the smart camera send me back a TCP command a as an output. by this way i could communicate with the smart camera . For transferring images I could not use the TCP step , so I turned on the smart camera web server to get the image by a browser Object . But the problem is that everything is going well with the TCP, but when I turned on the web server and try to communicate with it, sometimes I loose the connection with the smart camera. That is happened with the 1762 smart camera. But when I use the NI1772 it rarely happed.
Please help me. is there any other elegant way to communicate with the smart camera , and if a TCP and web server is a solution , Why the NI1762 web server is not stable ? Why i am losing the connection when browsing to the inspection page???
Thanx

Previous versions of Vision Builder had a COM library that you could use from Visual Basic 6 or other environments and talk over the network to a Smart Camera running Vision Builder AI and control its execution just how you are requesting. In more recent versions, this has been replaced by a native .NET and LabVIEW-native API that is much more fully featured. Unfortunately, I do not think the older COM mechanism is still available/supported (but I certainly could be wrong...).
However, one avenue you may wish to persue would be to call into the .NET interface from Visual Basic 6. Microsoft designed .NET to allow COM interoperibility in both directions (.NET can call into COM libraries and COM libraries can call into .NET). Take a look at the following document from Microsoft:
http://msdn.microsoft.com/en-us/library/zsfww439(v=vs.85).aspx
You could then look at any of the .NET (C#) examples to get an idea of the API:

Labview 2011 always disconnecting over wireless Ethernet bridge!

Hello, we recently upgraded from labview 2009 to labview 2011. We use a Labview cRio-9014 and FPGA backplane 9114. For connecting the cRio to our laptop we use Digi XPress Ethernet Bridge: Multipoint 900MHz industrial wireless part# XEB09. This program worked over our wireless link running labview 2009 with the old cRio software.
After upgrading the desktop, upgrading the cRio's software and recompiling the FPGA code we tested our setup via a wired ethernet connection and ran it all day with no problems. However once we switched to using our wireless ethernet bridges the cRio disconnects always 2-3 minutes after starting. It also does not allow us to reconnect without powercycling the cRio. The radio modems show a solid connect and no problems the whole time. Now I've searched through known issues and all over the forums without finding anyone having a similar issue so I hope someone can chime in and let me know if something else in LV2011 changed or what.
My current hypothesis is that labview 2011 uses UDP packets for status/keep-alive and our radio modems are not guaranteed to recieve all UDP packets. Please correct me since this is only a guess and I don't know what's going on under the hood on the cRio side.
P.S. I've captured the packet data using WireShark on the laptops side from deployment until disconnection but can't find any obvious problems. It's a fairly large file so let me know if it's needed and I'll try to find a way to upload it.
Hopefully someone can help.
