Webserver: open subVI front panels

[Snamprogetti]

When a VI is viewed in browser thru Labview webserver, and it opens a subVI with "show front panel when called", will the subVI be shown in the browser? Will it be a popup? If not, can this be achieved somehow?

Hi There,

I feel these two links maybe of use to you,

Please let me know your thoughts,

Thank you. They're a bit contradictory; first doc says all subVIs will popup, second doc says they won't, but i think it refers only to dinamically loaded and reentrant subVIs.

Hi,

I wanted to say that I felt this article was correct..

Can A SubVI Open Its Front Panel When Using Remote Panels?

It was written this year, compared with 2007. I am getting to test this out...

Hi,

I just wanted to confirm that using the web services the subVI front panel will not appear in the same web-browser page. 

To achieve this you have two options, as the knowledgebase articles were trying to explain - not very clearly I will admit, and hence I will edit them going forward.

1) Use a Sub Panel window to open the VI within the Front Panel of the Main VI.

2) Create a link on the webpage for the main (top-level) vi  to the subVI html file.

These both work for me. 

Just remember that the text you need to  add in the footer/header wherever in the main html file to create the link should be something like this, 

<a target="new window" href="SubVI01.html">SubVI Title</a>

 where the SubVI01.html is the name of the file the web tools tool created for my subVI.

 The steps then are best followed here,

Tips:

1) Make sure niwebserver CONF file has the correct Document Root - I couldnt get the default one labivew\www to work.

2)  Make sure the application configure settings file has WebServer.Enabled=True

3) Make sure the exe is running on the target machine - I just did this all locally.

4) During the exe build make sure you select to always include all SubVIs and html files you've generated. 

I hope this helps, but if you have any problems getting this to work please post back - as I have the setup working currently.
