CDE Front Panel w/remote X Server

Hi. I am running most solaris applications through the sun machine to another linux machine. The solaris box (10.0.0.1) has DISPLAY=10.0.0.2:0 (linux machine) which works fine. The only thing I am missing (I'd like to have) is the CDE Front Panel in the Linux X session. I can't seem to find it anywhere! Is it embedded within "/usr/dt/dtwm" ?

HI
Have you tried loading the Solaris 2.6 ftp patch 106522-04 ? It has
fixes for some mget related security fixes that were too restrictive.
You might be hitting that...

  • Display and interact with a vi front panel on remote C++ app

    Hello:
    I am new to LV and need a little advice.  I need to display a LabVIEW VI front panel in my C++ .Net application that users can interact with to view real-time spectrum data.  The C++ app (client) must reside on a separate computer(s) from the VI so that the client can connect from anywhere around the world and interact with the VI. 
    I am not sure about the basic architecture that should accompany a good solution.  We want to use TCP/IP but not DataSocket.  I do not have access to Measurement Studio but I do have access to LabVIEW Professional Development System v 8.2.  Can anyone provide suggestions on what I need to do in order to
    1.  Connect to my TCP server using my C++ client app - I have already written TCP client and server code which communicate but now I need to integrate LV
    2.  Get access to the VI sitting on that server
    3.  Send the VI front panel to the client for display
    4.  Allow the user to modify parameters on the front panel displayed on the C++ client, send those changes back to the server, and refresh the front panel displayed in the C++ client given the new parameters (I would like a real-time display of the spectrum to always be available)
    Is this possible?  Has anyone done this using C++ .NET in VS2005?  Are there examples I can mimic or references that will help direct me?  I have searched and searched through NI's help and found a lot of good stuff but I'm still feeling confused about the best way to utilize LV.
    Thank you in advance!

    One more question ... what if I could use Measurement Studio?  The documentation seems to indicate that it's easy to create network applications and therefore it would be easy for me to re-create our VI's front panel using Measurement Studio components in my C++ app and then simply connect those components to the networked hardware (TCP/IP or DataSocket) that could be located anywhere in the world.
    Depending on what components you are using in your LabVIEW panel, it is probably pretty easy to build a Measurment Studio application to look like a LV panel.
    Given that, you could use network shared variables to move data across the network, no TCP programming necessary -- I think that this is pretty easy to do, but I don't know the specifics about variable programming in that environment.  Also, you will probably need to add some smarts to the server side to make sure that it is reading to and writing from variables in an appropriate manner.
    Question: why can't you just use LabVIEW for the client application also?

  • CDE Front Panel change between sessions

    I'm trying to change the front panel workspace buttons so they change between sessions. However, when I log out and back in again they are reset back to "One", "Two", "Three" and "Four".
    After I changed the label on one of the buttons, I brought up the Style manager and selected "Set As Home". I went to the $HOME/.dt/sessions/home directory and found the dt.resources file did contain the new label for the button. However, when I log out and back in again the buttons are not set to the new value. What am I doing wrong, please?

    Hi Filip,
    About the 6 second delay. Did you changed anything in the "function generator.vi"?
    And when you change the amplitude of your signal, is it first displayed on the front panel,
    or does your output change first.
    I am asking you this because i have trouble opening the example. All our pc's have Labview 8.5 installed
    and 6.1 is just abit to long ago to be compeletly compatible. So i need to make an image of a pc then uninstall
    Labview 8.5 and install an older version. I can open the vi with 8.5 but many subvi's are missing and i can't run
    it so i can't see if i have a problem.
    So let me know if you changed anything? From what i have seen there isn't anything wrong with the vi.
    I think the problem is the following. When we select continuous generation we make the hardware fill a buffer with samples.
    so the buffer can be read every time at the same moment and the signal appears continuous. But let's say we change the signal,
    then it will only disapear after all the pervious buffer items are read out. So i think if you make the buffer smaller the delay should be smaller.
    Perhaps you can take a look at that too.

  • How do I programatically open a LabView Front panel?

    I want to use a test stand variable (perhaps a sequence global) to control whether certain VIs open their front panels, and wait for subsequent operator interaction. Can I get there using the API and something like this:  "Step_TSInfoProp.TSInfo_StepAdditions.LVStep_ModulePathProp" ?
    I tried passing a boolean to the VI and then having it optionally open its own front panel using the VI Server, but I could not see it because it would always be behind the TestStand Window.

    Sean,  The reason for doing this is that the client wants a "debug level" control of some sort. If set below some value, the VIs just do their thing, take their measurements, report, or whatever and go on their way blindly as what we expect a good test sequence to do. However when this value is set above some level (the threshold may be different for various categories of tests) the VI becomes interactive. This would allow an operator to see a measured value, and possibly tinker with the instrument parameters or the UUT, before continuing on. This might be similar to a single step command, but not necessarily pausing at every step. Inside of the VI I can test the value of the variable (either passed in through the connector pane or via the sequence context) and thus decide whether to be interactive or silent. I can also use the VI server to open my front panel or not.  But in doing so, even though I try to make the VI panel frontmost, it is hidden by Teststand. If the VI attribute is "dialog" then it does show up on top of everything else, but unfortunately does so even when I don't tell it to open at all.

  • Best Way to Host Front Panel in Web Browser

    Hello  All 
               I am almost confused with all methodology that Labview have to host the Top Level front panel in Web browser. My requirement is to  Monitor and control the Front Panel from remote location using web browser, but without installing any LV Runtime engine in Client machine. Also I want to stream the Videos in same or different page. Which is the best way to do this?. Web-service or CGI 
    Thanks & Regards
    Rigilkumar 

    Rigilkumar,
    If you don't want to install the LV runtime engine, that rules out the remote front panels.  However, you should still be able to build a web service to do what you want. This will be a bit more tedious because you'll have to build a thin client to have an interface with the web service. You can find an example of a thin client built in Adobe Flex here.
    If you're looking at streaming video as well, I recommend you look over Streaming IMAQ Images Over a Network (or Internet)
    Hope this helps,

  • Server does not support remote front panels

    hello

  • Do you need a web browser and internet server to run LabVIEW remote front panel?

    Does anyone know if ones needs an internet server to use the Remote Front Panel application of LabVIEW, or is it also possible to use a LAN/WAN for the same application?  if it is possible, how does one set up such a system?

    You can do this on any IP based system (which includes LANs).
    Basically, you need to be able to ping the server and to have the RFP port allowed in the firewall.
    Then you need to enable the option in the application. If this is an executable, you will need to configure this in the Options dialog or copy some lines from the LabVIEW.ini file into your EXE's INI file. You will also need to take the htm file created by the publishing wizard and make sure it points to your VI and that it is located in a place where it can be accessed from outside the server (read the LV help or search the site for more on this).
    Then, you just need to enter the URL for that htm file in the browser on the client (e.g. 192.3.42.5/c/rfp.htm) and it should load.

  • How to open remote front panel of vi's within an executable from an executable.

    How do I remotely open front panels of subvi's contained within an executable, where both computers just have LabVIEW Real Time loaded (programs are run as executables)? I want to use the Method: Remote Panel Open Connection to Server to make this work. I have been getting error 1032 "VI Server Access Denied". I do not want to use the web page method (connection is too slow when controlling front panel objects and I can not programmatically exit out (release control of vi) of the web page).
    Ex. 
    PC1: Has executable1 using Remote Panel Open Connection to Server Method etc. code inside. This program will make a call to executable2 (on PC2) to open up different vi front panels (within executable2), so the controls can be changed from PC1. I want to be able to make changes to the vi's running on PC2 from PC1.
    PC2: Has executable2 containing several subvi's.

    Not sure if this is what you are looking for but here is how to launch executables that can interact

  • How can I close a remote front panel by closing only the browser window?

    I control a remote front panel in a browser (from the client PC). If I don't use the 'close' - button in my program to end the remote front panel, but instead of this the 'x' of the browser window (in the right bottom corner), my program won't be close, it continues on the server. Do you know how to end a VI by closing only the browser windows?
    Thanks for any help!
    wolfe

    I found the examples. Thanks.
    But I could not find a solution yet. Now I know how to end a VI by clicking on the x of the VIwindow.
    My problem is, to end a VI by clicking on the x of the BROWSER window after I loaded and controlled a remote panel VI in a browser (e.g. IE).
    If you have any ideas ... I'd be happy.
    Thanks for your help.

  • How can I display the front panel of the dinamically loaded VI on the cliente computer, the VI dinamically loaded contains files, I want to see the files that the server machine has, in the client machine

    I can successfully view and control a VI remotly. However, the remote VI dinamically loads another VI, this VI loaded dinamically is a VI that allows open others VIs, I want to see the files that contains the server machine, in the client machine, but the front panel of the dinamic VI appears only on the server and not on the client, How can I display the fron panel with the files of the server machine of the dinamically loaded VI on the client computer?

    I down loaded your files but could use some instructions on what needs run.
    It seems that you are so close yet so far. You need to get the data on the server machine over to the client. I generally do this by doing a call by reference (on the client machine) of a VI that is served by the server. THe VI that executes on the server should pass the data you want to diplay via one of its output terminals. You can simply wire from this terminal (back on the client again) to an indicator of your choosing.
    Now theorectically, I do not think that there is anything that prevents use from getting the control refnum of the actual indicator (on the server) of the indicator that has the data, and read its "Value" using a property node. I have never tried this idea but it seems t
    hat all of the parts are there. You will need to know the name of the VI that holds the data as well as the indicator's name. You will also have to serve all VI's. This is not a good idea.

  • Remote front panels

    when I use remote front panels in LAbVIew 6.1, The Web Server and the client interact using DataSocket Technology through the ActiveX controls embebed in the web page?

    No, it is a low-level TCP based protocol that passes the data values and

  • Crio to host multiple remote front panels

    Hello all,
    I've a question abt remote front panel hosted by a cRIO system (cRIO9068 to be more specific, running RTOS).
    I have a top level VI (main) as the start up vi in my cRIO system, and it would call a subvi during run. I'd like to enable remote front panel for both the main vi and the sub vi so that I can see both front panels using a web browser. I'm not sure if such a configuration is possible at all and would like to listen to comments by users who have similar experiences.
    Thank you very much!
    Best,
    Jidong

    Hello hhaamm,
    To the best of my knowledge, I don't believe it is possible to host multiple remote front panels from the same executable, and, if it is, would be very difficult. The NI Web Server configuration file only specifies one port on which an executable can run web services, like remote front panels. In, short, I am not sure how you would be able to accomplish this.
    Another thing to keep in mind is that what you want to accomplish can be done in many different ways that would be much easier than creating multiple remote front panels.
    One of these is to move all of your controls and indicators to the top level VI. i.e. make the data you want to see from the sub-VI an output of the sub-VI and create a new indicator for this on your top-level front panel. This way you can still use a remote front panel and can use different decorations and labels to separate the top-level and sub-VI outputs.
    Another way to do this is to use the tab control to create multiple tabs, one for your top-level indicators, and one for your sub-VI indicators. This would still enable you to use remote front panels and would allow for the separation of your different indicators. Here is a note on how to do that:
    http://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/creating_tab_controls/
    And here is a more in-depth forum post on how to create them:
    https://forums.ni.com/t5/LabVIEW/how-do-you-create-tabs-on-the-front-panel/td-p/201495
    The final way I can think how you would accomplish this is to use a web service instead of remote front panels and host the output of the sub-VI as a separate website. 
    Hope this helps!

  • 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!

  • Configuring Remote Front Panels on a Real-Time Target,smart camera,but there is no image in the web page.

    I do see the web page, but the image  itself is not loading.i know a problem is with the installation of the LabVIEW ActiveX plug-in or the IMAQ ActiveX plug-in.  The LabVIEW ActiveX plug-in is required for ALL remote front panel viewing, and the IMAQ ActiveX plug-in is needed for VIs that use the Image Display. how can i do ?where can i get the the IMAQ ActiveX plug-in. help me！

    Got it working, after much experimentation.  Seems to require installing exactly the right combination of items on the RT target, as some items (web services? web configuration? the "application web server"?) apparently run a separate web server - or instance of the web server - on port 80, which prevents remote front panels from being served on that port.

  • Hi,why I have a "DMA hardware error detected" when I try to save file as *.htm for remote front panel application?
