Front panel publish error

iam using fp-2010 and labveiw 8.5.1 and rt 8.5
iam using a main vi in which i run another sub vi by giving path and using invoke node to run
i make html page of sub vi and try to publish it
when i simply deploy the main vi it works and i access page of sub vi
but when i make its exe or try to run main at start up it will not publish page of sub vi and give the following errorr(screen shot)

Why does my Web Publishing Tool fail to create an image of my front panel when I select the "Embedded" viewing mode?

I am trying to create an html file for access by a client computer through the LabVIEW Web Server. I want to enable the client to control the vi, so am chosing "Embedded" for the Viewing Option in the Web Publishing Tool. The small preview screen in the Web Publishing Tool shows an image of my front panel, but the resulting html file does not include this image. The Web Server error log shows a 404 error which I believe is due to the lack of an image (or any front panel objects) present in the html file: Error: 404 "Not Found" for "/.lv_frontpanelprotocol.rpvi100", file "c:/program files/national instruments/labview 2010/www/.lv_frontpanelprotocol.rpvi100": Can't access URL
If you are aware of this problem or know any solutions, please post a reply.
Thanks,
David

Does it work if you preview the web page locally?
Does the client computer have at least the minimum 2010 run time engine installed?

I created boolean references in my main vi block diagram and copied them to my sub vi front panel. when wire my reference in my main vi to one the input node of the sub vi the wire is broken. the error says its a class conflict why?

Expanding and clarifying what BJD said;
After you create the temporary sub-VI that BJD mentioned, open its front panel and copy the reference control that LV created when it created the sub-VI.
This reference control will be correct class etc that you need. Use the control to replace the original control that you were attempting to wire up.
The technique of "create sub-VI...copy" always works for me.
There is one more thing that you should watch out for.
The mechanical action of the boolean can not be set for latch action when attempting to read the value using a value property node.

Load error code 3 unable to load front panel

Hi all,
Wrote a vi in 8.6 and saved it for 8.5 for collaborators. When they run it up pops the error code 3 unable to load front panel. Memory full. see attached picture.
Has anyone any suggestions as to how to fix this?

Hi guys,
Thanks for the comments,
Attached is the code (zipped). Excuse the bulkiness of the block diagrams. It basically controls a rotation stage and makes an avi at specific times/angles. The motor stage is ActiveX controlled.
As I don't have access to the hardware I am writing semi-blind. However, when I did visit them and had a quick look at the code I could get it to work by quickly including the subvis into a new main vi and obviously compiling it in 8.5. (may be onto something here!)
Different versions of the labVIEW -> doing a group a favour; I have v8.6 they have v8.5, wrote it in v8.6 saved it for v8.5. I don't have v 8.5. I also have v 8.2.1 on a different machine. Saved it for v8.2.1 and it opened no problem in 8.2.1. Will send this version on and see how they get on. More likely to be forward compatible???
I agree that the optimal situation is 1) use the same version of labview and/or
2) they get someone to do their coding on-site!!!!
I think the corrupt front panel object could be true given that I could get it to work when the subvis were included in a new main vi on-site.
so versions 8.6, 8.5 and 8.2 attached.....

Leeser

Why do I get "error code 3: Could not load front panel" when I run my executable.

I have a LV 8.5 VI that controls only an agilent spectum analyzer. The agilent VIs call DLLs rather than SCPI commands. I created an application and an installer to load on a non LV machine and ran setup which was successful. When I run the EXE I get "error code 3: Could not load front panel" for each of my agilent spectrum analyzer VIs. I have to click "OK" about ten times, once for each VI. (My executable runs fine on all machines that have labview 8.5) The front panel does load with a broken arrow. The errors listed when the arrow is clicked for all of the Agilent VIs state: Missing subVI AGE444xInitialize.VI (or close.VI or read.VI etc.)
There is an AGE444x32.DLL in the data folder with the EXE file so I included as support both the DLL and all of the agilent drivers in the application build. Still no luck. I have built the application and installer about 6 times in various forms. I NEED AIR SUPPORT.
Unfortunately I do not have access to the internet at my jobsite so bear with me.

Hi V-rob,
I'm glad to hear the executable is working now that NI-VISA is installed. Thanks for posting the solution!

Publishing front panels with web server

Hello,
I'm working with LabView 7.1 and trying to publish a front panel by means of the web server.
The problem is that I'm only able to connect to the VI through the internet when both , the host and the remote are networked.
When I try with computers outside that network the browser doesn't find the webpage.
Thank you for your help
Lian

You need to know:
The public IP of your router.
The private IP of your LabVIEW server.
The port used by your server.
First you need to forward the port on your router. Basically, you need to tell the router that incoming NEW connections to a certain port of the public IP of the router should get forwarded your server. (Without forwarding, the router only works for outgoing connections). Once the port is forwarded, clients located on the outside need to connect to the public IP of your router.
Possible complications:
Your ISP might block certain incoming ports for security reasons. In this case you can configure a different port for the server.
With some routers you will not be able to connect to your server (for testing) with a client located on the same LAN via the public IP of the router. Only routers that incorporate a loopback proxy support this. What is the brand and model of your router?
Good luck!

How to: display large error note in the front panel?

hi guys,
When "error out" has an error, I would like to display HUGE RED TEXT in the FRONT PANEL saying: "STOP, ERROR DETECTED!" )
How to do that?
Thanks for your help.
Solved!
Go to Solution.

Place an indicator on the panel. Set the text to HUGE and RED, and set its value to "STOP, ERROR DETECTED!". Make it not visible. When you get an error, use the "Visible" property node to display it.
To learn more about LabVIEW it is recommended that you go through the tutorial(s) and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.

Error 1032 accessing Front panel reference on 6.1 EXE from 7.1.1f2

I am installing a Data Acquisition system developed in 7.1.1f2 (.net 2.0 patched). The system has 4 device drivers reading data from different components (SCXI DAQ, OPC/DSTP, DLL Library, and a Labview 6.1 executable) When I got on site, I modified the 6.1 EXE's INI file to allow TCP access to * and export * on a specified port. The driver accessing the 6.1 EXE was reading the digital values correctly but I also needed to read XY Graphs along with the plot configurations and coloration. I then wrote a simple debug VI that Connects to the 6.1 EXE's Win 2000 Machine the Application reference succeeded, I open a reference to the exported main vi and seem to access all the properties and methods of the VI except the Front Panel calls. Some of the calls return invalid data (read this is the default result if an error is encountered)and when I try to get the Front panel reference I get error 1032. I need to get this working in order to get the control references of the waveform graphs, in order to get the plot information.
Things I tried:
1 - I have tried accessing the FP reference from a different machine running LV 7.1 but still get the same error.
2 - The 6.1 EXE belongs to our client and we cannot modify it, but I have reinstalled it from the backups with no change.
I don't have any idea how to proceed..
What else can I verify on the remote VI server, Is there another way to read the plot data from a graph? (VI ref --> Get control value mostly works untill the fill color changes on the plots)
Any Help / guidance would be appreciated.
Darcy

Hello Darcy-
It sounds like you are running into a common problem when trying to access a front panel on a remote executabel. The following KB gve a bit more clarification on teh nature of the problem adn a possible workaround. The workaround will require modification of the EXE you wish to control, and it sounds like that may not be an option for you.
http://digital.ni.com/public.nsf/websearch/B36BCCBFEBECF4F486256C69005D49C3?OpenDocument
If the Vi you wish to communicate with is not written to share its data in any way, it is going to be difficult/impossible to read the the waveform vales from that VI.

How to handle LabVIEW Error 3: Could not load front panel

I was working on an application, running a vi when the computer turned off. It took me a little time to start the computer again (is not an old computer, is a P4, 1GB, ABIT IG7 MotherBoard). After I unplugged and plugged the Power Unit it was possible to start the computer, before starting, it says that a CPU problem occured and press F1 to continue. Afer press F1 Windows started normally. Then I tried to open the vi in which I was working when the problem occured and LabVIEW says:
LabVIEW: Resource not found.
An error occurred loading the vi.
LabVIEW load error code 3: Could not load front panel.
The question is, can I open my vi someway or I just lost it?
I will really appreciate your answers since I have been working for a long time in this vi.

Well, I'm faced with this problem now. VI started its life as a 9.01 LV 2009/Vision 2009 on a given machine. Copied to another machine wth 7.1, 8.2 and 9.01 on it. Opened with 2009, saved it for 8.0. Opened it with 8.2, saved it for 7.1. Opened it with 7.1//Vision 7.1.1, edited it, saved. File appears to be fine.
Now trying to open it with either 8.2 or 2009 (9.01) fails with error code 3. Note that it still opens with 7.1, so the front panel is there. Anyway to fix this?

Printer error on 8500 A910 front panel flashing lights.

I'm getting a printer error on an AIO 8599 A910, with all the lights on the front panel flashing. I restart, as prompted, but 2-3 minutes later, it has the same error message. I just (within the last week) did the firmware update. Any help would be appreciated. Otherwise, I'm dumping this thing.

All:
I'm on my second 8500. It was failing, too, and for the same reason. I switched over to a USB connection, and the problem ended. I also tried it again, but with hard wired ethernet vice wireless. Again, no problem. There seems to be a problem with the wireless circuitry used in the 8500, as well a a few of the Photsmart series printers as well.
I could not believe that it was this simple. I called HP, and pointed out what I'd found. The young lady who answered the call was very nice, asked lots of questions, checked with her folks there, and then cam back and said that if you go into the Network tab of them embedded web server of the printer, then go to network protocols, the select IPv4 ONLY, the problem will stop. I've not tried it yet, but I will. Perhaps some of you all who are having this problem can give it a shot and come back to the forum to let us know.
HP does have, I'm told, a firmware fix for this due, but....
Later,
JDM

VI Method "Front Panel:Get Image Scaled" Memory Error 17

Hi all, I've got two almost identical sub vi front panels that I'm dumping to a jpg image for reporting purposes. One was copied and slightly modified from the other to show a different data set and plot. The original works just fine, but the second sub vi, when using the "Front Panel:Get Image Scaled" method to pass the image to write the jpg, always returns the following error:
"Error 17 occurred at Invoke Node in Myprogram
Possible reason(s):
LabVIEW: Not enough memory to manipulate image.
=============================
NI-488: Unrecognized command.
Method Name: Front Panel:Get Image Scaled
[Continue] [Stop] "
I've stripped the problem section into a simple tiny new that only opens the report and tries to get the image with the same working/non-working result above. Using the Execution Trace Highlighter, it error is definitely occuring when the Method executes.
Any ideas? Thanks.

Hey cjgpr,
I haven't been able to dig up much info on this error message. There's one other discussion forum post that talked about it some, and a KnowledgeBase article on it. It seems that whatever changes you made to the front panel have caused it to exceed your computer's memory when creating an image. Try removing items until it works, then see what actually breaks the functionality.

LabVIEW error code3: Could not load front panel.

Hi
I am getting second time the "LabVIEW error code3: Could not load front panel." when working with the development environment of LabVIEW 2009 SP1.
It is really annoying as I loose time as I have to revert to saved previously code.
Does anybody know where it may be coming from and how to avoid it?
Thanks
Pawel
Solved!
Go to Solution.

Pawel,
the panel has an origin which you can see in your VI:
Every element will be placed in a position in regard to this origin:
The position has a limit in regard to the bound. I am not sure about the value, but it should be around -35k...35k (or the double of it)....
hope this helps,

NI DC Power Soft Front Panel Error - 200247

Hello All,
I am having trouble opening the ni DC power soft front panel. The error message I repeatedly am seeing is below:
When I try to run the vi mentioned in the error above, the same error occurs:
How can I go about getting my soft front panel to work? I have been using the DC power API to execute tests over the past week using the example VI's, but am at a point where the soft front panel would be very helpful to my workflow.
I am using the following:
NI PXIe-4139 SMU
NI PXIe-1082 Chassis
NI PXIe-8360 Controller
Windows 7 64bit
Labview 14
MAX 14.5.0f0
DC Power 14.2
I have tried running the soft front panel using clean installs of DC Power 14.1 and 14.2 and see the same error message. I have uninstalled the other modular instrument driver packages on my computer, NI-Fgen and NI-Scope, reinstalled DC Power, and still I see the error message. It could be that I am not uninstalling these software packages 100% correctly (I use the windows add/remove to NI Remove software dialog process....)
I appreciate any help getting this DC Power soft front panel working.
Thank You,
Andrew Goett

Hi Andrew,
Can you possibly give me a MAX technical report for your system? The instructions can be found here. Use Method 1.
Also, can you check which version of niModInst.dll you have on your system? This file can be found here: <Program Files>\IVI Foundation\IVI\Bin\niModInst.dll
Right-click on the file, select Properties, and then click on the Details tab. The information I need is the "Project version" field. See the image below:
In addition to the MAX report, could you send me a ZIP file of the contents of this folder: <Program Files>\National Instruments\Shared\niModInst
I've attached a simple program (NI-ModInst Code.vi) to test if NI-ModInst is failing across the board or if it only is failing to identify NI-DCPower devices. Open the program, select a driver that you have installed on your system, and run the program. The code should tell you the number of devices you have in the system that are associated with that driver, as well as list out the model numbers for those devices. This list will include simulated devices. Test the code with various drivers in your system to see if you get the same error.
Let me know how this works out.

Publishing VI's on the Internet without open front panels

I'm using LabVIEW 6.02 and are publishing VI's on the Internet. I'm wondering if it is possible to publish VI's without having the front panels open when you are running the program?Or do they have to be open to be in memory and to be able to get updated front panels?
(I use the .snap command so it is possible to refresh and get updated VI panels.)
I also wondering if the only difference between .snap and .monitor command is that you can use the refresh command with monitor so the labVIEW display will automatic updated itself. This is not possible with the .snap command?
Thanksregards Anne

I've never tried to exactly what you are talking about but a similar issue comes up when printing. A front panel normally won't update unless it's open. The way to insure that it does is to have at least one property node on the routine's block diagram. When LV sees the property node, it goes ahead and updates the front panel even when it's closed.
Hope this helps...
