remote front panel cannot load in browser but works from labview

[SidMayer]

Found it!  finally...

In a way it was a dumb mistake, but not completely obvious.  The VI and the web server were fine all alone, as you might expect since the remote panel could be accessed from within LabVIEW.
The problem is that I opened the cFP in Internet Explorer through an FTP window in order to copy in the web page, so I used a URL like:
        ftp://192.168.0.10/ni-rt/system/www
then dragged in the web page.

I tried opening the web page by double-clicking on it from that view!  That's the problem, IE opened the page, but not really from the web root, so when
the browser control tried to load the remote panel, it did not work correctly.

When I finally started with a different browser window and went to http://192.168.0.10/whatever.html, everything works fine, including my more complex app.

I would, however, contend that the browser plug-in should have much better error reporting.

Thanks for all your help!

I have a similar problem.  I have created an Compact Fieldpoint application.  I can view the remote panel on a IE window from the computer it was created on (Windows XP sp2), but not on a Windows Vista system.  I have installed the LV RTE 8.5 on the Vista system but it still doesn't work.  The browser brings up the Web view with the Title, description and footer that I created but the actual VI shows 0% of 0 bytes and doesn't go further.  I have turned of the Virus and Firewall stuff still nothing.  Any suggestions?

Hi Bob,

Are you using the default Web Server settings (Tools » Options)?  Specifically, are Visible VIs and Browser Access set to allow access?  Have you tried a different port?

Hi Jennifer,

  I am using the default Web Server settings.  Visible VI is set to allow access and browser access is set to Allow Viewing and Controlling.  I am able to access the remote VI on 2 different Windows XP systems.  I just can't get access using Windows Vista.  The screen stops at 0% of 0 bytes.

Hi Bob,

Is there a browser plugin located at C:\Program Files\National Instruments\Shared\LabVIEW Run-Time\8.5\Browser Plugins\Internet Explorer?  It should have been installed with the LabVIEW 8.5 Run-Time Engine.  Also, I assume you have  Administrator privileges if you were able to install the run-time engine. 

Are you using the same version of Internet Explorer on the Vista and XP machines?  Was the VI developed in LabVIEW 8.5? 

These answers should help narrow down the error.

Hi Jennifer,

    The plugin (LV85ActiveXControl.dll) is in the directory.  The application was developed using LV 8.5.  The browsers used on the XP systems are both version 6 and 7.0.573 and work.  They also use 128 bit cipher. The version on the Vista system is 7.0.6 and uses 256-bit cipher.   I do have adminstative privs.

p.s.,  I don't know how I managed to have so many version of the reply popping up.  I hit an enter the next thing I know there are 4 or so posts with nothing by Hi Jennifer.  Sorry for the wasted bandwidth.

Hi Bob,

I was able to view an embedded VI on a Vista 32-bit machine using Internet Explorer 7.0.6001, 256-bit cipher. 

Is there any difference in how your XP and Vista machines are connected to the network?  Although I realize you disabled your antivirus software and firewall, are you aware of anything else that could be blocking communication on port 80?  That is the default used by the LabVIEW web server and can be added as an exception to any security software. 

Does your Vista machine show as a remote connection when you view the web page?  In the development environment select Tools » Remote Panel Connection Manager, which will display any connection and its status.
