Flash in web-based remote panel??

Hi,
I have a question. I found this vi from ni.com (http://sine.ni.com/devzone/cda/epd/p/id/3891). It plays flash clips. However, I have a problem creating a remote panel for this vi. When I go to web-publishing to create a html for this vi and open this html on the development computer, the flash play on the vi instead of on the html. I did not try on client computer since it does not work on development computer.
I also tried building the vi into an exe (I include html and swf as supporting files). I run the exe before opening the html and it does not work either.
I have attached a sample flash file below. Could anyone give me some idea on how I can play a flash on remote panel??
Regards
Lee

Hi Lee,
I was running into the same problem as you were trying to play the flash file. I could get it to work in LabVIEW but in the web browser it would not display properly. Have you tried any other flash files than this one? I believe the reason for this is the limitation Remote Front Panels have when using ActiveX objects. Since the drawing of the object draw and operate completely independent of LabVIEW, this is where the problem comes in. You can read more about the limitations of the remote front panel in the help files of LabVIEW.

Shared variable browse in a web published remote panel

Hallo,
I have made a simple VI where the user can select a shared variable and show the current value.
I use a shared variable control to let the user select the variable from the panel.
Everything run smooth if I interact directly on the server where the VI is running.
This VI is published on the web and when I access the VI form a web browser I cannot browse the shared variable list.
The pull down control is empty and the 'browse' text is disabled.
Is there any option to have the shared variable list browsable on the web published panel ?
I think this should be possbile since the VI is running on the server where variables are published.
thank you
Gianpiero

Hi
I suppose you used the shared variable control to implement your vi. In this case i have to inform you are using a ActiveX control that related to LabVIEW remote front panel shows some limitations.
For more details i suggest you to visit this link which contains a list of the limitations you should keep.

Web based Front Panel

Hello,
I want to place an interactive vi on a website. From what I have
gathered from the help files the ni solution is non-interactive.
Is that correct? Are there unix friendly ways of loading vi online?
Thanks

For NI's remote front panel to be interactive, you need to install the LV run-time engine on the controlling computer.
If you want a JAVA based solution, try looking at LabVNC.

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

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.

FieldPoint WEB Remote Panel Tab Control

Using a TAB control on Fieldpoint (FP 2000) and Labview 7.1
I wanted to implement a password feature mainly for the Web browser
remote panel feature for my Filedpoint application, as suggested in "Developing Remote Front Panel LabVIEW Applications"
http://zone.ni.com/devzone/conceptd.nsf/2d17d611efb58b22862567a9006ffe76/e789515b9976253786256b1f007e039b?OpenDocument#5
(see bottom of the page)
"Alternatively, you can program security into the VI itself. For
example, you can require a user to log in when the VI first runs, and
disable all other aspects of the VI until you verify the login. To do
so, place a login field on one page of a tab control, the other
controls on subsequent pages, and enable the other pages after the user
successfully logs in.
I find that I can "Hide tabs" using the "Page Selector Visible" feature
if the Remote panel is hosted by Labview in Development Mode but this
feature does function with the Web remote panel mode. In fact you can
use the Tab Control normally from the Web remote panel.
I find that I can disable a specific tab if the Remote panel is hosted by Labview in Development Mode but this feature is ignored by the Web remote panel mode.
Thus: -
Do you know of any limitations (a list would be usefull, if there are specific limitations)?
If its a limitation, is it of FieldPoint or the Web remote panel or the Runtime Engine installed in the Browser or ...?
Do you know of a better way of getting a password feature.
( I am aware of IP security available - the IP
addresses are DHCP supplied - " 'Doh' says Homer Simpson", the P.C's
will change as well)
I lookforward to any insights..., wisdom or experiences you may have had

2 player web-based Flash game problem

I have a two player web-based Flash game. The Flash calls a
JavaScript function on the webpage to get and store the user's IP.
Then an XML file with user's game data is loaded and parsed. The IP
address is used to identify which player is player 1 and which is
player 2 according to the XML file. There is a Java applet to send
and receive messages between the players.
The first player loads everything just fine. All the first
player's messages regarding the progress in loading different parts
of the code sent by the game for debugging are displayed in the
Java applet's text box, but none of the second player's messages
sent by the game for debugging are displayed.
The problem is that the second player's ActionScript code
appears not to be executing except that I do get a message in the
game that the XML file attempted to load but was not successful.
The IP address call is not made and no messages can be sent to the
other player. The second player's Java applet displays only the
messages for debugging that came from the first player's game and
any chat messages sent by the first player.
This problem always happens to the second player, never to
the first player. Both player's are always using IE6 or IE7.
Does anyone have some idea(s) what could cause only the
second player's ActionScript code not to execute and/or not to load
an XML file correctly?
This is just a general question, so any general answers would
be appreciated. Code specific answers are hopefully not required.
Thank You in advance.

Hi,
I am not very familiar with the multiplayer Game development. For multiplayer games, you'll need to set up a matchmaking server and have the clients connect to it. It can then pair them off and facilitate communications. If the clients have publicly available
network addresses then it can introduce them and they can talk directly to each other.There isn't anything built in for this so you'll need to either build your own or find a third party implementation. If you are using Unity3d then check out
http://docs.unity3d.com/Documentation/Components/net-MasterServer.html
Also, you can use Xbox services, and I find an article below:

X Pro and Flash Player Error with web-based PDF readbook

Everytime I try to view a web-based PDF book (with multiple PDF files) I get an error/alert that reads:
"To View the Flash technology content in this PDF file, please install this version of Flash Player that supports Adobe Reader and Acrobat."
I am currently using:
IE Explorer 9.0.8112.16421
Adobe Reader X 10.1.7
Adobe Acrobat X Pro 10.1.4
Shockwave 12.0.2 Development
I have all of the appropriate settings enabled/disabled in the browser. Before I installed Adobe Acrobat Pro the files opened perfectly in IE9. I believe, but am unsure, that I was just using Reader X at that point.
Of note...the PDF books in question still open perfectly if I DOWNLOAD the file and open it from the desktop. The issue is when I try to view it in the browser(a setting enabled in the preferences). This is an issue because I don't have the time or space to download these files and need to view them in the browser for efficiency.

You would usually get this message if you don't have the Flash Player plugin installed. However I do not quite understand why you get that message when viewing a PDF in the browser, but not when viewing it from your local disk.

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.

Dear John H.
Thanks for the answer
I created the VI to observe the image from WEB-camera
When I run the VI, I must to set the resolution the WEB-camera.
When I run the VI on the host computer , I can do this.
But when I run the VI on Remote Panel, I can’t adjust the resolution of the WEB-camera from Remote Panel and the VI are stopped
What can I do?

Viewing web pages from remote panel error

I used an activex container and put the web browser object into it. Next thing I knew, everytime I would open that vi's remote panel via the web server, iexplorer crashes. What gives?
Grub
Hell, there are no rules here...we're trying to accomplish something!!! - Thomas Edison

Grub,
How is Internet Explorer crashing? Does it stop responding, or
give an error? Does the LabVIEW program have any errors on the
host computer? I did find a KB that talks about the limitations
of remote front panels, and it mentions that ActiveX will not work, but
does not say anything about crashing Internet Explorer.
Check out the KB
Repost with any additional information.

I need to run web based Microsoft CRM. I open it in Safari but the program does not respond. I suppose it has to do with Flash or ActiveX. Can someone help?

I need to run web based Microsoft CRM. I open it in Safari but the program does not respond. I suppose it has to do with Flash or ActiveX. Can someone help?

What does the product developer say about system requirements? If it needs to be run from within Internet Explorer then you'll need to find a way to run Internet Explorer. Boot Camp or VM installation of Windows would be two options.
But first check the product requirements.

How can I protect files from being uploaded to the internet/web-based email or being written to a disc/flash drive?

I work for a company that want to update itself to this century. I got all our PC upgraded to Windows 7 and networked into a homegroup. We want to use a web-based appointment scheduler but this means giving our users web access. The main
concern is our .mdb files. We have anti-virus/anti-spyware to protect us from infiltration but we want to safeguard against personnel selling our client list; At least make it more difficult, just a precautionary measure. Do I need additional software
or is it something that I can do in Windows setting? Or do I need a file encryption service that works in conjunction with Windows Access? Sorry for my ignorance and thanks in advance.

There is technology known as RMS which you could set series of policies like only members in the company could access certain documents and if someone copy them and attempt to run them in another PC or outside company, it won't work. Take a look at:

H.264 Web based Encoder Demo

Hi,
before some weeks ago i red a newsletter that adobe has include a h.264 encoder in FP 11.
Well, here we go i thought and start to develope a web based h.264 encoder for our CDN. Here is a first version that i want to share with you developers.
Onlinelib Web Encoder Version 0.2:
http://onlinelib.de/labs.html
Please do not use this in serious projects. You will need also a RTMP Server for testing and of course a web-player. I will include a player option inside the encoder for internal testing.
There are a lot of features missing, but the basic h.264 encoding is working on my Mac Pro and our CDN.
What i found out during the development:
Please correct me if i post something wrong.
Contra:
- AAC Encoding for Audio is missing. Without AAC we cant product ipad / iphone compatbile streams. Flash iOS cross-compiler supports CPU native speex decoding, same for nellymoser, but you cant mix them cause native h.264 decoding in iOS is also not working and you cant send the iOS native quicktime player a bytearray for decoding h.264.We can have access to the raw micro data, but its useless cause you cant transmux the packets to the camera stream. I think a native AAC encoder in AS3 or alchemy is possible but without more access to the encoder its useless.
- No Stereo Encoding. That is really a big minus point. I study all docs and cant find if its possible to encode 2 channels.
- No access to compressed frames for video or audio. Without getting access to the compressed frames we cant use HTTP streaming, packing for the new HTTP protocol that is accessable sinse FP 10.1. In times of hacks and security its important that we developer can protect our streams with own encryption technologies. Not possible right now. RTMP(e) is a option, but this encryption is really useless (my 2 cent mind). A DES is stronger than the hole RTMP(e).We also are not able to calculate our own bandwidth alogs.
- I thought that adobe will include VP8 Encoder / Decoder in FP11. I hope they will do this.
Pro:
- I think the encoder is based on MainConcept SDK, works for me. Baseline and Main is fast enought toDo realtime. I cant find a way to set motionVectors, bframes that can be used in mainprofile. I saw that in some level(s) profile h2.64 the encoder makes some strange colorspace effects (false colors).
-We can change cameras, micro, bitrate, fps during a streaming-sessions. That´s cool and not possbile with Flash Media Desktop (FME) Encoder. You have to disconnect the FME first, then set the changes re-connect again.
- p2p is also working and you can mix server and p2p. We port the rtmfp protocol to an embedded device:
http://walyou.com/img/world-smallest-pc-space-cube-4.jpg
The p2p option in the public encoder is not useable cause adobe has patent-rights on the rtmfp protocol. If i have time i will inlcude a cirrus service.
Best,
Gary
http://onlinelib.de

Thanks for the input. What do you mean by encoding it as H.264 not mp4 - which setting affects that?

CFP2120 remote panel shows "downloading panel 0% of 0 bytes" but never loads the panel

body {margin:8px} .LW-yrriRe {font:normal x-small arial}Good morning,
I've been trying to run a remote panel with a cFP2120 upgraded to LabVIEW
2009 & fieldpoint 6.05 (it was on labview 8.5 with 6.01) to no avail, the
program runs ok in the project manager and runs on the fieldpoint but the remote
panel doesn't. I would like to know if anyone else runs remote panels with 2009
and cFP2120s and if so was there any tricks required?
Things I've tried:
Upgraded and installed latest labview Runtime.
Tried on PC's running XP/XP Home/VISTA.
Tried with both Mozilla and Internet Explorer
Tried using a different port
Disabled firewall.
Using full name for html file
check html source code.
New project with simple program (flashing LED A on cFP), this works
Tried on two different cfP2120's
tried reformatting and reinstalling the s/w on the cFP
The front panel works fine with LabView 8.5 and FieldPoint 6.0.2
thanks for any help.

I believe that this may be a problem with the conversion from 8.5 or 8.6 to 2009. We recently ran into a problem that was similar to this. The steps that we performed to correct this were:
1.) Created a project (with only one VI called test_vi_851.vi) in LabVIEW 8.5.1
that I built into a real-time exe with a remote front panel and got all of that
working.
2.) Closed LabVIEW 8.5.1.
3.) Manually rebooted the cFP-2120
into Safe-Mode (by flipping the dipswitch on the front of the controller).
4.) From MAX, formatted the disk by right-clicking the controller under
Remote Systems and selecting Format Disk.
5.) After the controller rebooted,
reset my network configuration and name of the controller and hit Apply
(controller rebooted again to apply these settings).
6.) After the
controller rebooted (still in Safe-Mode), I added software to the controller
(FieldPoint 6.0.5 with LabVIEW 2009, controller rebooted again).
7.) After
the controller rebooted, I manually switch the Safe-Mode dipswitch back to off
and then rebooted the controller again from MAX.
8.) Launched LabVIEW 2009
and manually opened the VI (test_vi_851.vi, just the VI, not the project).
9.) I went to File»Save As... and selected the option Copy - create copy on
disk»Substitute copy for original.
10.) I then chose to name this copy
test_vi_2009.vi. Then I closed the VI, which brought me back to the LabVIEW 2009
Getting Started window.
11.) Selected Empty Project and then targetted the
cFP-2220.
12.) Enabled the Web Server by right-clicking the
target»Properties»Web Server»Enable Web Server. Then I deployed this setting to
the controller by right-clicking the target»Deploy.
13.) Returned to MAX and
rebooted the controller.
14.) After the controller rebooted, I manually
added test_vi_2009 by right-clicking the target»Add»File... .
15.) Opened
test_vi_2009 from the project and created a new html file (called mypage.html) using the Web Publishing Tool.
16.) FTPed mypage.html
to the appropriate folder on the controller.
17.) Returned to MAX and
rebooted the controller.
18.) After the controller rebooted, I ran the
test_vi_2009.vi from the project and was able to access the remote front panel
(http:///mypage.html).
Please give these steps a try, and let me know if you run into any further problems.

Workaround for Sophos anti-virus blocking remote panel

Hello, I was hoping if anyone had some suggestions regarding working around an antivirus.
I'm trying to have a PC act as a web server for some Labview embedded remote panels. Unfortunately whenever I tried to load it in browser on both the local host and other computers connected to the network (even very simple test VIs), I get the 0% downloaded problem people have had in the past. Since I have admin privileges on the host computer I have discovered that by disabling the antivirus (Sophos Endpoint Security and Control, ver. 10.2) completely fixed the problem for that machine.
My problem is that I intend for students to use the VIs and they do not have the access rights to disable Sophos so they too will be able to use the panel. Faculty IT are unwilling to modify the antivirus for the computer lab PCs so it is down to what I can do on the server PC to fix this problem.
Does anyone have any suggestions to work around it? I've tried a couple of different ports for the web server (8000 & 5000) with no luck. Snapshots come through fine, it is only the embedded ones that get blocked.
Any help would be appreciated.
Specs:
Labview 2011 with Run-Time Engine 6.1
Windows 7 (64 bit)
Anti virus: Sophos Endpoint Security and Control, ver. 10.2. On-access scanning is causing the issue.

I guess you have to ask IT which ports you can use, e.g. 8080, from the top of my mind.
