Labview closing intermediate windows and verifying if library exists

Hi,
I have 2 questions.
1)I have an application file.First I see my main window and then I can press a button and
another window opens.After the second window finishes the extenuation I can still it .Can I pragmatically define that every intermediate will be closed
after execution?
2)Is there any function in Labview that checks if a certain library exists in my computer?
I couldn't find such function.
Thanks,
Leonid

Hi Leonid,
1. If the intermediate windows you are referring to are subVIs called by your main VI then you can programmatically get the front panels of the subVIs to close by writing a true constant to the Close After Call VI Property node.
2. I am not aware of a single function that checks to see if a library exists, but here is a link to some documentation about how LabVIEW searches for a library when it is called:
http://digital.ni.com/public.nsf/allkb/EBAE870D564CBBE78625788B004E76D3
The first related link at the bottom of this article (LabVIEW 2011 Help: Specifying the Locations of Shared Libraries on Disk) includes a section about how LabVIEW locates missing shared libraries. You might be able to use part of this process to find a particular library.

Hello Wyodor,
thanks for your reply on my question.
You are wright the index file is 308 KB.
And offcourse that I delete my files and documents is not an Iweb problem, but because my English is not that good, that I thougt I try to tell the whole story, and hope people can read trough the lines.
Why I didn't use Iweb to upload to the server is because the server company recommanded to use file zilla. And I am a nobody with this kind of things, so I did exactly what they tell me to do.
No, i did not make a backup of Iweb and the domain file, but reading other messages on this forum showed me that I can maybe try to make empty the cashfile (?)
and otherwise I have bad luck and have to make my website again. Offcourse I have a lot of examples from all the pages (copied from the local map to my USB stick) and my website is aprox. 15 Mb, (not so big) so it will cost me a few nigths.
But I'm still hoping on a miracle :-)
greetings Lasource

Firefox exe continues to run after closing all windows, and consumes massive amounts of cpu

after closing all firefox windows and trying to reopen i get the "firefox is still running but unresponsive" message, and have to go into task manager, processes and end the firefox exe, which is consuming between 96 and 100 cpu.

Norton IPS is apparently a known issue being mentioned in the KB articles:
*[[firefox will not start]]
* [[firefox crashes when you open it]]
* I also found an earlier post on the Norton site http://community.norton.com/t5/Norton-Internet-Security-Norton/Norton-IPS-1-0-Addon-for-FireFox/m-p/25425#M8494 but I am not sure this is still considered a problem.
What exactly is this IPS extension. I am currently using XPs with Norton's NIS (version 18.6 - it is a paid for subscription). I do have Intrusion Prevention active in NIS but I see no specific extension or program IPS. Is this some optional additional software?
I did find an explanation but from 2009
* http://community.norton.com/t5/Norton-Protection-Blog/Intrusion-Prevention-System-IPS-Your-first-line-of-defense/ba-p/124400
I am NOT using the Norton Toolbar etc. is it these components that are causing the problem i.e safe search etc.
I am not having problems with firefox hanging or continuing, despite using NIS.
There is a bug on this https://bugzilla.mozilla.org/show_bug.cgi?id=548945 but that does not seem to have got very far in confirming or resolving the issue. I imagine Norton have a very large userbase and it seems unlikely that the basic NIS is itself incompatible with Firefox.

After closing all windows and trying to open a new window I get a message saying Fire Fox is running in another open window

When I close all windows and try to reopen fire fox I get a message that fire fox is already running in another window and needs to be closed to restart.

There are a few possible causes for that error, for details see [[Firefox is already running but is not responding]]

I accidentally closed the window and I can't restore my previous tabs

I tried to restore the window but my tabs didn't come back. I hadn't closed Firefox and it didn't crash, so the auto recover has nothing to do with it.

Did you check if you can reopen that window via History > Recently Closed Windows ?

ITunes Windows and sharing OSX library in bootcamp using MacDrive

Hi,
Has anybody been able to load iTunes on their Windows partition and, using MacDrive, share the iTunes library on the OSX partition or hardrive?

okay, let's start from the beginning
what you want to see in iTunes is this (view from my MBP's iTunes seeing the library on my Mini)
if the icon looks like this , home sharing has not been set up correctly.
in order for home sharing to work
(a) iTunes on all machines must be authorized for the same iTunes store account
(b) all machines must be on the same network
(c) all machines must have access to the internet.
are the above points a given on your end ?

Can you build an Labview app on windows and run it on the Linux Runtime Engine?

Our developers work on windows workstations but we would like to convert our test stands to linux. Can we run the apps they develop on Linux with the Linux Runtime?

No. VIs developed on Windows will run in the LabVIEW Linux development (assuming no Windows specific functions like ActiveX and DLL calls) but in order to run a built application on Linux you will need to rebuild them with the Linux application builder.

Shortcut? Closing one window and not the program.

Is there a shortcut on the keyboard to only close the top window in safari and not close the whole program?

Hi Lan4
Here are more shortcuts you can use in Safari

Also in the HELP menu in Safari just type 'shortcuts'
Good luck ...

LabVIEW: The VI is not executable. Most likely the VI is broken or one of its subVIs cannot be located. Open the VI in LabVIEW using File Open and verify that it is runnable.

When trying to run a sequence on a deployment machine I get this error. When I switch the Adaptor back to the Development System the problem goes away however I do not have the luxury of keeping the full Labview development on the test machine. Is there a know fix for this problem and what is the cause of this error. Here is the software and versions I am using. It seems that the vi's that are broken are using Invoke and Property Nodes within them, I am not sure if this is just a coincidence. It appears it is more related to the invoke node than the property node. Any help is greatly appreciated. Why does it seem everything works great until you try and deploy it on a test machine. This is not the first time I have had these kinds of problems using Nation Instruments software.
Labview 8.2.1
TestStand 4.0
Solved!
Go to Solution.

I have a similar problem.
A bit of background - I had developed a test suite with a Labview front panel for manual operations, and a Teststand project which used some of the same lower level vi's, and specific test step vi's. It was developed on LV 2010 32-bit and Teststand 2010. All was fine.
Recently i had to rebuild my development machine and installed only LV 64-bit 2011 and the latest (2010) Teststand from the 2012 Dev Suite.
I knew that i wanted to run some new hardware drivers in 64-bit versions due to another problem, so i replaced the .dll in the very lowest level VI with the 64 bit version. And ran the manual interface. All ok.
But when i try the Teststand execution, i get one of two errors:
- If i set Teststand to use the LV runtime engine 11.0.1 (2011 SP1), the i get a "Unable to load VI xxxxx with the runtime engine version '11.0'" Despite the fact that each VI does run correctly in LV dev when loaded individually, and i've saved them as version 11.
- If i set it to use the development system (which shows in the config menu 'active version:32-bit' even though 32-bit LV is not installed), then i get the "The VI is not executable. Most likely the VI is broken or one of its subVIs cannot be located." error, even though i when i open each VI in the LV 2011 it runs ok.
Any ideas?
How can i set TS dev system to use the 64-bit version? Or is there a separate 64-bit deployemrnt of TS?

INSERT INTO new_dept( deptno, dname, loc )
SELECT deptno, 'foo', loc
    FROM dept;Collections can be handy if you need to apply a bit more conditional logic, though.

[S] Firefox hangs on KDE install after all windows and tabs are closed

When I launch Firefox from KDE, the process hangs around consuming ~70-100% CPU of at least one core after closing all windows and tabs. We have to kill the process manually or say File->Quit and issue the real exit command instead of just closing all tabs. I ran strace and found that Firefox is poll()ing something as fast as it can after all windows are destroyed, causing the CPU increase. Anyone know how I can fix this? I've already tried a different profile and pacman -Rnd to no effect.

I've solved this by removing gtk-qt-engine; without gtk-qt-engine, firefox behaves as expected.

ITunes 9 - Using 'Home Sharing' between Windows and Mac libraries

I have my main iTunes music library stored on my Windows 7 PC. It is currently around 200Gb in size, so pretty large.
I want to be able to use 'Home Sharing' in iTunes 9 to access this library on my Macbook over my home wireless network.
I don't, however, want to copy the music files themselves over to this laptop, but simply access the library over the network, and play them via either iTunes 9 or Front Row.
I would appear that the Windows and Mac 'iTunes Library' xml files are incompatible. I can't 'Alias' the Windows library on the MacBook for this reason. Does 'Home Sharing' eliminate this problem? Is there a way of accessing the library on the Windows PC without copying all of the files over to the MacBook?
I want to maintain a single library (which is often changing with new podcasts etc), rather than 2 libraries which I have to keep in sync.
Does anybody have any ideas on this one? I'm sure I am not alone in having this problem.
Here's hoping...:)

Finder search opening in new window and sidebar gone

Hi, just wondering if anyone could shed some light on this cause I'm quite lost.
First of when hitting Command-F in the Finder it opens up in a new window, I'm pretty sure it didn't do this before. Opening folders does not open in new windows. Using the "Go" menu also has the same behaviour. However it's not really a big issue.
Secondly and this is what's irritating me the most, the sidebar disappears when doing this. Toggling the sidebar and closing the window and starting a new search makes no difference, still no sidebar.
I have done some pretty major changes to my system recently, and even if I don't really see why it would have effects like this (havn't noticed any other changes). What I have done is that I have moved /Users/* to a separate volume and is mounting the volume as /Users using fstab.
I tried experimenting a little with com.apple.finder.plist and removing the file (i.e. letting finder recreate), this caused the sidebar to appear, however adding:
<key>CreateDesktop<key>
<false />
Made it disappear again, freaky if you ask me... I have had the desktop off for ages without any problems so don't see why it wont work any longer. Or if it only has to do with this key and not also others.
Property list is here (for one month) if it helps: http://pastebin.com/TYGsWj9T

Okay, this is wierd (and embarrasing), everything suddenly started working again after days of not working... Did nothing I can think of, only thing that I have done actively is that I have defaulted property list and restarted Finder multiple times. I even reverted back to the old property list and it still worked, maybe some cache problem? (which I didn't think of till now) but otherwise I don't know, thanks for reading my question at least .

New tabs open in new window or in a pre-existing window that was not currently being used.

What has been happening is that I was running two windows of Firefox at the same time and when trying to open a new tab, the new tab would open in the window that I wasn't currently using. Afterwards I closed one window and upon trying to open links in a new tab, instead it would open a new window.
I have checked the option settings that opening a new window would open a new tab instead is on, which it is.

This can also be a bug.
