Question about subvi front panel

I want to call a subvi in the main program and do like
this:
1. When the main program calls the subvi, the subvi shows its front
panel and executes.
2. After the subvi finishes, it can close the front panel.
Now, I meet a problem: I can popup the subvi node setup dialog to enable
"show front panel when called", which implements the first one, but I
can not close the front panel until originally closed(main
program stops). How can I close the subvi's front panel(after it
finishes running) even when the main program is still running?
Thanks in advances.

I think a more elegant way of closing the SUB VI is to start off the way
that Remco states regarding opening a VI reference. Only in the Sub VI,
you should program a Terminate control (such as an Abort button to exit
from a While loop... or something similar) and via the VI reference,
select the 'Set Control Value' method to gracefully stop the Sub VI
execution. Of course the Sub VI will have to set the close if originally
closed attrib set.
There is a great source of example LabVIEW apps at:
http://digital.ni.com/explprog.nsf/web%2Fswgrp?OpenView&Start=1&Count=50
0&Expand=3.7#3.7
In particular, see "Stopping a Running SubVI from the Main VI Using VI
Server" example. It demostrates this techniques better than I can
explain it. Hope this help.

Main VI Menu event calling a subVI front panel

Hi all,
I have a subVI whose front panel is loaded upon calling by a main VI.
I call the subVI using a User-menu event.
the subvi-properties are set to allow close window and i am not handling a 'panel close' event.
The problem is....
when i run the main VI and click on the menu that loads the subVI front panel, subVI window opens, and if i click on the window-close, the main VI hangs.
i understand that the control remains with the subVI only and never returned to main VI after i close subVI panel.
but is it the only way to handle the 'panel close event' or any other way out to solve this?

Try running the VI with highlight execution turned on, and see if anything unexpected is happening, or you could post your vi and let us take a nosey

Reference to control on main front panel fails when subvi front panel is closed?

Hi All,
I'm experiencing an odd bug. In my code, I use a subvi to control a piece of hardware. This subvi has controls for all of the functions of my hardware.
I'm changing the value of one of these controls from my main front panel by running a reference to a knob on my main front panel into the subvi, grabbing the value of the knob with a property node, and then updating the value of the subvi control using a signaling property node.
This works fine when my subvi front panel is open but fails to work at all when the subvi front panel is closed.
I'm new to labview , so any help is appreciated.
Thanks,
Arpan

What is your LabVIEW version?
Front panels that are not shown are typically not updated and might not even be loaded into memory.
The presence of certain code elements (e.g. property nodes) often forces the front panel to be in memory even if it is not shown, but I haven't studied it in a long time so there might be subtleties. Maybe somebody from NI can give more details.
If it does not work unles the FP is open, open the front panel minimized to avoid distraction.
Can you attach some code? Maybe there are better ways to do all this anyway.

Question about the custom panel language

I have a question about the custom panel language...
The document you provide seems to lack details on some features. Namely the icon and picture widgets. I see from looking at the examples and other vendor's web pages that these features exist, but I don't find any detailed descriptions of them in the documentation. Is there a more complete document describing these and other features...
http://www.adobe.com/products/xmp/custompanel.html
Alternatively, can someone fill me in on the syntax and options for at least the icon and picture widget. For instance, how do you load external icons or pictures...
Tom

Gunar,
It could be interesting to have something like
icon(url: 'http://www.adobe.com/Images/logo.gif', width: 20, height: 20);
or better
picture(url: 'http://www.adobe.com/Images/logo.gif', width: 20, height: 20);
for the pictures and
include(url: 'http://www.adobe.com/xml/custompanel/camera1.txt');
for include the cusmtom panel's dynamic portions

Problem about asynchronous call: subVI front panel doesn't pop up when called.

Dear All,
I'm new to LabVIEW, and this is the first time I try to use the asynchronous call.
I'm using LabVIEW 2011.
I want to build a directory for several VIs, and it should allow users to open more than one of the VIs at the same time by pushing the buttons. Before building this directory, I simply tried to use asynchronous call to call a VI form another VI, but found a big problem.
I followed the steps in the help file, created a strictly typed reference, set the option to x80 because I don't need the return. When I run it for the first time, it worked fine: the subVI popped up and run. Then I closed the subVI. But for the sencond time and on, when I run the caller VI, the subVI didn't pop up, instead it seemed to run silently on background because when I manually opened it from the file I found it running. Besides, I didn't find any option like "show front panel when called" of the asynchronous call.
The caller VI and subVI are attached. The address of subVI in caller VI should be changed accordingly.
What should I do to make it work properly? Thanks very much for any idea!

Jeff, you will be happy to know that I used this tactic in full force on a project recently (lots of dialogs in this program). Not sure how many LabVIEW reboots it has saved me from. Reuse VIs made it even easier to do.

How can I close all open subVI front panels, without closing my top level VI front panel when all VIs are built into executables?

I'm using the code shown in the sample VI discussed here: http://digital.ni.com/public.nsf/allkb/353A696A3F393D9B86256E8B007A2912
to close all open VIs except my top level VI. My top level VI is actually a separate executable and the sub-VIs are their own executables. All reside under the same project. It works very well if I'm running in LabView but will not work when I build them. I added all the sub-VIs to the Always Include box in my top level VIs properties which did nothing. I also tried adding them to the Startup VIs box. This allowed me to close them all programmatically from the top level VI but it also open all the VIs at once (which was expected and not desired). I think the problem is the executables are not able to see outside their own memory space so the top-level VI never finds any other open front panels to close. Is this correct? Is there another way to go about doing this?
Thanks!

Where do I begin…..
I’m using a “server” to control 4 “client” PCs. My server opens references to 4 VIs on each client then executes them sequentially. So on a normal day, the server will run everything itself and I will have no contact with the clients. But on a several occasions, I’ve needed the ability to walk up to one of the clients and run just one of the 4 VIs.
We are updating from LabView 6.1 to 8.5 and we want to run executables rather than VIs for various reasons. I have a new VI running on the client PCs who’s only function is to initialize the shared variables and open/close the VIs. I initially thought of making the remaining 4 VIs sub-VIs but I will loose the ability to run them individually. I think I would also have to rewrite the VI running on the server since the 4 references it originally opened do not exist. I don’t think you can open a reference to a sub-VI on another PC. Can you???
As you can see, this is a huge mess. I’m still pretty new with LabView so any help you can provide would be great.

Question on closing Front Panel references

I'm manipulating controls on the Front Panel of my VI. In doing this, I open a slew of references (to the VI, to the Front Panel, to its Panes, and to the objects on the Front Panel). Normally, before exiting the VI, I carefully close them (in LIFO order, of course), but a question has arisen:
I want to "export" a series of references to Boolean controls for use in succeeding VIs. No problem, while enumerating the controls (see above), I simply identify the Boolean references and build them into an array that I pass out. First question -- does anything "go wrong" if I also do a "Close Ref" in the main loop (after adding the reference to the array, of course)? [At present, I'm only doing a Close Ref on the non-Booleans]. Logic says this should be OK, as the Close Ref is mainly doing "garbage collection", and I've done a "copy" operation in building my array, but to a persistent structure.
Second question -- in my "cleanup" routine, I noticed I was "double-disposing" of the references, that is, I did a Close Ref on my array of Boolean References, but also was enumerating the entire Front Panel (as I did when I opened it) and disposing of the references that it found. Again, this should be no problem, but (in principle) I'm doing a Close Ref on two references to the Boolean control. It occurs to me that this is not really logical either -- I should be able to simply "abandon" the array of references -- although it takes up memory that can be "reclaimed" for other uses, the fact that it is an array of RefNums is a "so what" -- the contents of the array could have been a numeric or other "solid" data type.
Does this make sense? To summarize, what I'm trying to do is to "extract" some RefNums to Front Panel objects for later use. In the "extraction" process, I must open (and create references to) multiple objects, including RefNums to my "objects of interest". What I think I can (and should) do, once I've copied the RefNums I need, is to dispose (Close Ref) all of the RefNums that I opened during the extraction routine, and do something equivalent when I do the subsequent "cleanup" (which undoes any modifications I made as part of the extraction).
Comments welcome.
Bob Schor

I usually store the ref. at the beginning of my program, in Functional Globals, and i close them when the program does not need them any more.
I think this is the right approach. And it is simple

Plotting to a number of asynchronously called subVI front panels

Hello everyone,
I'm working on a DAQ and monitoring program and I have a dream of doing some very flexible window management for my plot windows. Trying to make it easy to quickly open different kinds of plots and display different channels in each window. So as not to reinvent the wheel I'm trying to use Windows windows to do this by calling VIs asynchronously. The VI will be built as an EXE and used by people who don't know LabVIEW, hence trying to make it really flexible and intuitive.
I've set up my VI like this example and it has me real close: http://zone.ni.com/reference/en-XX/help/371361J-01/lvhowto/acbr_call_clones/
When I run the VI it opens whatever number of plotting windows (instances of my plotting window SubVI) I've specificed but the plots don't update. Anyone have any tips as to how to get this behavior?

Bob,
Thanks for the reply. I'm using a QSM-PC architecture, here's the relevant loop. Looks pretty much identical to the linked example, I hit that point and I decided I needed a bit of help wrapping my head around it. Data's coming in on a queue (the snippet broke the reference). My idea was to pop open all the windows in this state then use another state to plot data to them.
In 'synchronous' mode I was able to get the desired behavior out of my subVI but it was also set right in a while loop and by playing with the Call Setup a bit I got it to do what I needed (open a new front panel and constantly plot).
The queue idea is very promising though! I should be able to generate queues right in the For Loop that calls my VIs synchronously then enqueue in a "RUN" state. I'll give that a try.

Question about the FRONT ROW REMOTE

ok i have 2 questions about this remote.... i ordered a Mac Book Pro and am waiting for it....
Well the 1st question is that has anyone use Powerpoint or Keynote with this remote. That would be great for keeping me mobile while giving my speeches...
2nd. Is the IR "eye" in the computere sensitive to other products. Maybe a cell photo that has the obex all locked up (thanks VERIZON)....
any info would be great
steve

Sorry to disappoint you but I don't think it is that kind of a remote. It seems to be designed strictly for audio/video software. I have tried it with both Keynote and PowerPoint and all it did was effect iTunes that was running in the background.
As far as other IR devices; I aimed all the IR remotes I have and tried different buttons. Nothing happened. But things like TV remotes usually have to be coded to the specific devices you wish to have them operate. If you purchase a Universal Remote for your TV, DVD, VCR, etc., you have to tell it what the brand and model are, usually from a list of codes that come with the remote.

Question about Spry Collapsible Panel

Hey guys my question is that I have a PSD sliced and imported into Dreamweaver and I was wondering if it was possible to have a Spry Collapsible Panel drop down from a button I designed in Photoshop and brought into dreamweaver? Basically I want a content area to drop down when that button is clicked and I figured a Spry Collapsible Panel might be able to accomplish that. I hope I'm explaining this clearly enough, I'm not very experienced with Dreamweaver. Thanks!

Definitely possible.
You should first import the image into DW.
Insert > Spry > Spry Collapsible Panel
It'll insert a demo panel.
You'll then have to move your image <img src..> into the default first div under spry collapsible as follows:
<div id="CollapsiblePanel1" class="CollapsiblePanel">
<div class="CollapsiblePanelTab" tabindex="0"><img src="location-to-your-image.jpg" width="100" height="50" /></div>
<div class="CollapsiblePanelContent">Content</div>
</div>
You'll basically be removing 'TAB' from here to replace it with your img src tag.
Your HTML should look like this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Collapsible Test</title>
<script src="SpryAssets/SpryCollapsiblePanel.js" type="text/javascript"></script>
<link href="SpryAssets/SpryCollapsiblePanel.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div id="CollapsiblePanel1" class="CollapsiblePanel">
<div class="CollapsiblePanelTab" tabindex="0"><img src="location-to-your-image.jpg" width="100" height="50" /></div>
<div class="CollapsiblePanelContent">Content</div>
</div>
<script type="text/javascript">

</script>
</body>
</html>
Do note that you'll have to copy the supporting spry files to your server for this to work. By default, DW will place them into your project folder once you insert the spry collapsible panel.

Questions about SB0250 Front Hub

I have an Audigy 2 SB0240 and I would really like to get my hands on a front hub SB0250. First and foremost, are these two compatible with one another? I really need a SPDIF input for my home theater setup so I want to make sure these are going to play nice together.
Also, anyone know where I can buy one? ebay has some but they are selling with the card for $200+ im hoping to score just the hub for <$30.

Is it possible to change the DNS servers? No, you can not change the DNS servers on the homehub
Can I put my gateway in bridge mode? When you say gateway, are you meaning putting the Homehub router into bridge mode. If so I don't think you can but others may be able to advise.
Can I use another gateway instead of the BT Home Hub 5 if I wanted to? Again if you are refering to the gateway as being the router, yes you can replace the HH5 but you would need to either get an Openreach modem for the router to work or get a VDSLmodem/router.
Also have some questiiions about my Infinity connection.
I noticed that my Home Hub is connected with an RJ11 and not a RJ45. When I look at BT's broadband packages it says "Fibre optic broadband" when looking at the unlimited BT Infinity 2 package. As far as I know RJ11 is used for a copper and not a fibre? BT Infinity is FTTC, Fibre to the Cabinet. From the cabinet to your house is through your copper telephone cables.

Question about the front headphone jack and the X-Fi SoundC

I just bought the ExtremeGamer Fatalty Pro series card and have a question. This is my first time building a pc.
<font face="Times New Roman" size="2">?
I have a headphone jack on the front of my case in the bezel that plugs into my motherboard. Do I remove this connection (HDD/AC 97) from my motherboard and plug it into the SPDIF I/O connection on my X-Fi card? (hehe it fits) Or is the only way I can listen to my head phones is?on the back of the card? Meaning; now that im using the sound card and my onboard sound will be disable is headphone jack on the front no longer in use, dead?
Im in the middle of the build, and wanted to ask before I powered up and ruined something.
Thanks in advance!

B&Just realized that the Beta driver introduced a new problem. ?Although the inputs are now working, the sound is terrible. ?The volume keeps fluctuating rapidly (not the level that I can control). ?If you leave the volume at a set level, you can notice that it is behaving erradically.

Simple (?) question about Spry tabbed panel

Hi, I'm a bit of a noob at DW and am wondering if there's any way to open a link from within a Spry tabbed panel, and have the content load in the same panel.
I would have thought this would be simple, or even default behavior, but every target I try opens a new browser window or just loads it over everything in the current window.
Any advice would be greatly appreciated.
