Get the view of the VI in remote panels through the Web.

[Groupe ESIEE]

For viewing a front panel remotely in a web browser, I guess it is possible to use Labview plugin instead of RTE which requires administrator rights on client machine (Windows 2000). What is the URL I have to used in the "pluginspage" parameter of the "embed" object ?
I used pluginspage = "http://digital.ni.com/express.nsf/express?openagent&code=ex87nm&" few weeks ago, but code is now invalid.

The link says you have to use the RTE WITH the plug-in, not that there is a separate plug-in available.

Can I get only the browser plug-in from somewhere? As the whole RTE is >32 MB to download I would like to have a smaller download file which only contains the web client functionality... Is this possible?

Thanks

I try to publish vis through the web but when i run the page, no images appears.
With FireFox, it tels me i have to get the plugin and with IExplore i have a message that tells me "the server can't display this image", or something like that. When i tried to get the plugin with firefox, i was droped on the Labview RTE downloding page... So i tried to install this one but an error occured that told me "the runtime is alredy installed"...
So what have i to do to get this front panel image.
I have seen when i download the RTE, that when we install the runtime, we have to ticks an option to get front panels visible. It was not done (i think) and i can't see how to do that now.
Can you help me please.
Thank you!

Hello all,

You will find extensive documentation on this in the LabVIEW Help (click Help -> Find Examples... in LabVIEW).  Search the phrase "web publishing tool" (without quotes) and you'll get a list of relevant documents including the following titles:

1. Creating HTML Documents and Embedding VI Front Panel Images

2. Publishing VIs on the Web

3. Viewing and Controlling Front Panels Remotely

4. Embedding a Front Panel Image in an Existing HTML Document

5. Embedding a VI in an Existing HTML Document

6. Viewing an Application or Front Panel Remotely Using a Browser

7. Web Server Syntax Examples

8. Web Publishing Tool Dialog Box

There are more there as well, but hopefully this sampling gives you an idea for the information you'll find there.

I hope this helps!

Best Regards,

JLS

I'm afraid that doesn't help me!
Is there any one who know the solution?
I have done that i have learned in scool, and the it worked very well, but here,in the company, it doesn't work!!!

Hello,

I don't think I understand exactly what you're having trouble with, but documents I referred you to above constitute almost everything you will need to know about the web publishing tool.  If you can be more specific about your problem, I can try to help you, but if you haven't actually read through the documents I noted above, I highly recommend you do so.  There are syntax examples and explanations which should help you understand fundamentally how to use the tool, afterwhich you can apply that knowledge to your specific situation.

Best Regards,

JLS

I use the french vesion of Labview, and when i go to search examples, with the example browser, and i ask for "web" in the tab "search", it gives me the following answers : HTML Report, Test Report, Text Report. Nothing about that i want! And when i click on the tab "Browser", nothing most significative appears.

My problem is that i want to see the dynamic remote control through the web, so i have used "web publishing tools...", then, i have given the name of the vi and chosen in the "view option", "control and  monitoring". I have saved the html page in the root server directory and click "ok"!
When i try to run the web page, that doesn't work. with  MS IExplore, on the frame where must appear the vi, the following message is visible:
"the client does not have access to the remote panel server".

Hello again,

Ok, that sounds like a standard use case - just viewing the published front panel.  When you say, "root server directory" do you mean the C:\Program Files\National Instruments\LabVIEW X.x\www directory?  I will post here a standard answer I have prepared regarding remote panel access in LabVIEW - it includes instructions for how to deterministically get started, and then we can deal with any differences from the standard case that you might require.

Here is the standard answer I composed:

The web publishing tool allows you to publish the front panel of any VI to the web using LabVIEW's built in web server.  Then, based on IP address you can either allow people to view and control the VI remotely, or simply view the VI, or deny access altogether; these are configuration options you have for the built in web server.  You can also configure which VIs are even viewable (ie. exported for view).  For a web published VI, LabVIEW simply posts the current image to the web and then allows access to the VI per your configuration.

The basic steps are:

1. Enable and configure the LabVIEW Web Server; see Tools -> Options... in LabVIEW, and then "Web Server:" drop down category selections in the window that pops up.
2. Publish the VI of your choice using the machine on which the VI will run; see Tools -> Web Publishing Tool... in LabVIEW, and the window that pops up will allow you to customize the web page.  You can further customize the web page by modifying the html document directly.  When you click Save to Disk an html file with the name of your choosing will be written to
C:\Program Files\National Instruments\LabVIEW 7.1\www

All you have to do then is record the URL that is assigned to it and use it in your favorite browser; the form of the URL in general is http://yourIPaddress/nameOfYourVI.htm

Note that when the URL is constructed, every space in the name of your VI will be replaced with %20.  Thus, to avoid strange looking URLs, simply name the VIs you wish to web publish without spaces.

I hope this helps you get started, particularly the basic steps.  There is actually more to the standard information, but I didn't want to throw too much more documentation at you at this time!

Best Regards,

JLS
