Hi Syd_b;
The error you are receiving is probably being generated because the LabVIEW Web Server is not enabled in your machine, in this link there is a document that explains how to enable it for other PCs to have acces to the content you are publishing.
I hope the information is useful.
Good Luck

File Dialog's using Remote Panels (via web server)

I am aware that the web server remote panel access will not allow us to open a file dialog box on a remote computer. I have read people comment that you should create your own file dialog box, using LabVIEW to use instead of the file dialog box.
Has anyone actually done this? I would like know if anybody has source code for this, rather than re-inventing the wheel. Also, will the sub-vi actually just appear on the webserver? i.e. will it actually work?
Thanks for any help
Slade

Hi Emilie,
I have a program that I run on an industrial PC, with no keyboard, video or mouse. We currently control the application using the web server. We have a button to load and a button to save settings. If the files are missing for the load & save, it pops up a file open dialog to choose the file to import. However, while we are viewing the page this way, these dialog boxes do not work.
I would like to know if anyone has made up a file dialog box that I could use, that would display correctly in the web server's remote control.
Regards,
Slade

What is the Algorithm Used by the LabVIEW Remote panels?

Hi
Has any one had any idea about how dose "LabVIEW Remote Front Panels " works and its Algorithm?

Is it possible to intercept data values transferred from server to
remote computer display and put them in a text file for post-processing
? Each data value is accessible individually with graphic cursor but I
don't know how to store the whole set of data.
Thank you for your help

Invalid server IP address for Remote Panels under LV 8.0.1

The other messages for troubleshooting the "invalid server IP address" were very helpful with getting my EXE to operate as a remote panel. But there is still one issue that I cannot resolve that seems to be caused by the 8.0.1 upgrade.
The remote panel work perfectly using IE6 on a computer that has the LV 8.0.1 FDS or PDS installed. When I use a computer that has LV 7.1 or no LV at all, the invalid server IP address appears inside the border of where the VI should appear on the HTML page. The connection to the remote computer is correct, the HTML file is delivered by the web server in LV, but the panel part of the page returns the error.
Does the part of the HTML that loads the Run Time Engine need to be updated for 8.0.1? Will the LV 8.0 RTE work for a remote panel on an EXE compiled for LV 8.0.1?
The code is:
var obj = '<OBJECT ID="LabVIEWControl" CLASSID="CLSID:A40B0AD4-B50E-4E58-8A1D-8544233807AD" WIDTH=1216 HEIGHT=915 CODEBASE="ftp://ftp.ni.com/support/labview/runtime/windows/8.0';
if (lng.indexOf("fr") != -1) { obj = obj + '/French'; }
else if (lng.indexOf("de") != -1) { obj = obj + '/German'; }
else if (lng.indexOf("ja") != -1) { obj = obj + '/Japanese'; }
obj = obj + '/LVRunTimeEng.exe">';

Thanks for the suggestion, Tunde. After further experimentation, it seems that 8.0.1 was not the problem. I worked perfectly when I removed the <parameter server=... > line that I added manually.

Server does not support remote panels

I am developing an online laboratory setup and hence am using a client server model..the client VI being accessed by remote users online. I have done all the necessary steps using Web Publishing tool and the configuration set up. I have also tested the VI previously online. Suddenly now when I hit the URL for the VI the panel does not load...it says Server does not support remote panels. What could be the problem?

see answer given second posting of question.

Server does not support remote panels, server overwhelmed

After an unknown amount of connections to remote panels, I recieve the "server does not support remote panels" error. Often times it will further say server is overwhelmed. It seems like sometimes we can have almost 100 succesful connections without the error and sometimes just only 10.
Ive combed over all other similar posts regarding this error and most others seem to have an issue with the initial connection, not after numerous succesful connections.
This error can be resolved by restarting labview; however, restarting means interupting some physical processes that are running in our warehouse. Is there a way to locate and empty this log that appears to be overwhelming the server?

Thanks for the reply.
Using Labview 2013 Full Development on windows server 2008. IO communication done through compact field point modules. All remote computers used to access remote VIs have been loaded with the correct runtime engine. The issue seems to happen on the server end because once it happens, all remote computers get the same message, instead of one isolated computer having an issue.
There doesn't really seem to be a pattern to this error occuring(to my knowledge). Sometimes we can go a week or two without seeing it, other times, a few days. We upgraded to labview 2013 and the new server almost a year ago. This error didn't start happening until after about 4 or so months of use.
I came across this knowledgebase earlier this week and have verified that all of our settings are correct.
Thanks again for the reply!

Remote panels- server running application in log-off locked mode

I have not used remote panels before and was pondering if they would work if the server (Win Xp) running the application goes into workstation locked mode.
Company IT policy dictates that all PC's must go into locked screensaver mode after 15 minutes of inactivity. To reactivate, the user must log back in. Of course any applications continue to execute normally while in locked mode.
Would another user at another PC be able to view/control the front panel of a LabVIEW exe remotely while the server running the application is in locked mode?
Thanks

The remote panel should continue to run while in locked mode. If another user wanted to open the remote panel and view it, that should be ok too. Remember that there are limits to the number of users that can be viewing a remote panel. The limit depends on how many licenses you have. info here
Because only one user can take control of the vi. If the second user wanted to take control (and the first user had control) then the second user would not be able to take control. The solution to this is to set time limits on how long a user can have control. This is a configuration setting.

How do I run Remote Panel Connection Mgr on server with just runtime & exe

We are running a LabVIEW 6.1 executable on a PC with Windows2000. We have remote panels enabled and the system seems to be working fine. However, we would like to be able to run the Remote Panel Connection Manager in order to monitor the load we placing on our communications system. I can run it while in development mode, but the option is no longer available under Tools once I create the exe. On the actual server machines we do not have the full development system (only the runtime engine) installed. Is there a way to run the Remote Panel Connection Manager while running just the exe with the runtime engine?

The manager is a separate VI. It's located in \project\remotepanel.llb. You could try building an separate exe from it or including it as a support file in the exe you want to run as a remote panel. If it does run, you might have to create a custom menu in order to call it from your exe.

Remote panel / Web server. II part ?

Hi all
There has been some activity about remote panels / web server in this forum.
Basically, NI documentation states LV run time, at least, must be intalled in client PC to use that feature.
In this link to post
a post from NI engenier Jeremy L. says that just to monitor a remote panel vi, NI soft is not necessary in the client PC. That option looks very interesting.
So, my questions are:
1- Somebody got to monitor a remote vi if LabView or run time is not installed in client PC.?
2- Can NI peo
ple clarify this option?
3- What is, if anything, the minimun NI soft required in client PC to monitor a remote vi front panel?
Thanks in advance

Well as I said for monitoring, NO NI software is necessary. For Remote
Control you basically need the lvrt.dll runtime and some supporting
files such as lvapp.rsc.
As the runtime gets more and more complex it is not a good idea to try
to install individual files. Eventhough the lvrt.dll contains up to now
all the code necessary to execute simple LabVIEW programs there is more
necessary to be able to for instance display the LabVIEW 6.x 3D controls
(all of the
models directory is then necessary) or in the case of the
web plugin I would assume the lvpng.dll and lvjpeg.dll will be also
necessary.
Also some registry settings have to be set so that the plugin or LabVIEW
application can find the appropriate runtime engine, unless you want to
copy all the necessary files into the same directory as your application.
In view of this I would not even consider getting a LabVIEW runtime
system onto a computer other than by adding it through the application
builder to my executable, or running the official NI runtime installer.

What are the network requirements for the Remote Panel Server?

What are the network requirements for the Remote Panel Server?
I've been trying for a while now to setup a Remote Panel. I can connect to my computers remote panel from other computers on my LAN but nowhere else.
When ever I use the web publishing tool it gives me a URL in this format: http://Computer-Name.Corporate-Name.local:8086/VI-Name.html Apparently this means I have a local DNS server and this URL has no meaning from the public.
When I try connecting with the Operate>>Connect to Remote Panel..., I get this error message:
"Connecting to remote panel server...
Remote panel connection refused by specified server: Make sure LabVIEW Web Server is enabled on specified server"
I got the same error when I tried to host a remote panel from my laptop at home, on my Wi-Fi. Is there some network or firewall setting I'm not seting? Could it be my server or router or private network?
My goal is to be able to host Remote Panels from my laptop while I am travailing internationally, by using 4G mobile internet. Is that even passable?

Error code 1 remote panel close connection

Good Afternoon,
i'am working with the web publishing tool utility of LabVIEW 8.6 to open vi files (front panels) remotely. I've programmed a server in LV that receives querys from a web server/client programmed appart (not in LV). I got to open the vi files remotely, executing it embedded and allowing the user to take the control. Afeter some minutes i want to close the conection with that remote panel. For doing that, i have used the Invoke Node with the method -> RP.Close Connection to Client which uses the conection previosly searched with RP.Client connections. The problem that I have is the next one:
Many times, this process works fine, but some times, it appears the following error:
                     Error 1 ocurred at Invoke Node in ....
                     Possible reasons
                     LabVIEW: An input parameter is invalid. For example if the input is a path, the path might not contain a character not allowed by the OS    such as ? or @
                     Method Name: Remote Panel:close connection to Client
I've checked the path that taht methos is using and it doesn't include any ilegal character, the path is the same that in other times when it works fine. With this porblem I can't close the connection what it'sa really necesary for my work.
Has anybody idea how to fix it?
Thank you very much!

Could it be a LabVIEW bug? I've heard that labVIEW 8.6 has some troubles with web service

Open url in a remote panel

HI.
I want to put a button that launch a webpage. I works fine locally, when I click OK button, a new internet window browser is open with the URL.
But if I take the control in other PC client (using Web Publishing Tool) and I click OK button a internte window browser is open in THE HOST. I want to open the new window in the Client.
Thanks.
I attach the VI (open_google.vi) and the HTML file created by WPT (test.txt)

Hello,
When you view or control a VI using Remote Panels that VI is executing on the host side. The VI will not be able to interact with the operating system on a remote panel client. This means that it will not be possible to use this approach to open a browser window on the client side.
You could take another approach- at least the way I would do it is thusly:
Instead of putting the button that launches the page in the VI you could put it in the html file that the remote panel is hosted in.
Using javascript you could pop up a new browser window with the URL you need.
If you need to control what URL is viewed from within the VI you could make the button point to a URL that will be handled by your VI that can redirect to the URL you need. This would be easy to do in 8.6 as you could simply export the VI as a web service. Pre-8.6 you would either have to use the G web server or build a minimal web server yourself (this would be easier than it sounds since the server would have to do nothing but redirect).
I should add that this approach would require some knowledge of HTTP/HTML/JavaScript.
Let me know how it goes.

Can multiple PCs access one remote panel at the same time?

I've written a program in labview 7.1 to monitor/control a labview application running in the test cell through Remote Panel. I and my coworker can remotely monitor and/or control this labview application individually. But if my coworker has the remote panel displayed on his PC and I try to get the remote panel on my PC, I get a labview error (63) as below:
"LabVIEW: Serial port receive buffer overflow.
LabVIEW: The network connection was refused by the server."
My question is: Can multiple PCs access one remote panel at the same time?
Thanks in advance!

Sorry I wasn't clear. The remote panel license is separate from the number of LabVIEW development licenses. Pricing information on remote panel licenses can be found here.

How can I disable messages generated by Remote Panel?

I created an application (EXE) to server its panel to other network clients.
I used the Tools > Web Publishing Tool to generate a HTML code to create two different web pages to access this application using Web server:
- Embedded (for some users who need visualize the panel in real time).
- Monitor (to display panel snapshots to users updated every 1 second).
I don't need anyone controlling the remote panel, so I used this option:
Tools > Options > Web Server: Browser Access and checked Allow Viewing (not controlling) for every client connected.
Ok, both are working fine. But it a user try to Request control of VI on the Embedded page (right click in the remote panel), the application running in the server displays a message: Denied control request from XXX: Check permissions.
The embedded page stills working fine, but in the Monitor page that message appears in a box (see attached picture below)..
Is there a way to disable all messages in the remote panel? I realized that I need to access the computer where the application EXE is running to close the message.
I'm thinking in two solutions:
- Unable the right click menu in the embedded page to avoid clients request control of the remote panel.
- Run a code in the application to erase messages generated.
Has anyone an idea how to solve this?
Thanks in advance,
Klein

Hi Dpcamargo,
I'm already using monitor with a delay of 1 second and this doesn't seems real time like remote panel visualization.
But you sent me a good tip: use java code to cancel right clicks at all....
I will try this solution.
Hey, we are both brazilians! So, thank you so much, Dpcamargo.

Remote Panels not working in embedded viewing mode

Hello,
I'm trying to develop a web version of my project using Labview remote panels. I configured the web server properties as it's described here: http://www.ni.com/white-paper/4791/en/
Currently I'm trying to create the web page on the web publishing tool. However when I select the Embedded viewing mode option I get an "Requested VI is not loaded into memory on the server computer" error on the web page that is created. But if I select Snapshot or Monitor viewing mode option the page is loaded without problems.
I'm using Labview 2013 and oppening the web page in google chrome. The VI from which I'm trying to create a remote panel has some subVIs that show the front panel when called. Is there anything I'm forgetting to configure, or do I need to have any plugins instaled on my browser?
Solved!

There you go, good solution. When doing this remember that you have access to the database on the server. A structure I have found effective is to use the server DB like a dropbox that I write to, and the web server reads from.
