Strange behavior in LabVIEW palette

Hi all,
I am writing a LabVIEW API for a device that my company is developing. Just today, I noticed there were "X"s in the lower left-hand corner of the VI icon in my palette. What does this mean? I've never seen this behavior before. The VIs can still run properly though.
Couple of clues that might help:
1. These VIs are linked to a common typedef that I use to define one of the inputs. I tweaked the typedef a little last night.
2. These VIs are linked by a common lvlib, however I don't think I've changed the linking structure of the lvlib.
Baffled. Truly baffled. I'll try installing my API on another computer to see if the same syndrome pops up.

Think I found out what's going on. These VIs that are being referred to from the palette are being embedded in a lvlib, which is also embedded in another lvlib. Usually when LabVIEW has trouble linking to VIs, I find it's because of the lengthy file path that's being referenced. For example, in my case, the path would be C:\Program Files\National Instruments\LabVIEW 2011\user.lib\<XXX API>\<YYY function>\<ZZZ.lvlib>\<AAA.lvlib>\<something.vi>. That's a real long path for LabVIEW to swallow. I've ripped out some of the nested lvlibs and the crosses seemed to disappear (for now.) Will keep everybody posted.

Strange behavior of stop control with events

I have found some strange behavior while using stop controls. I have a main vi which has two while loops. One of them is used to continuosly acquire the images. The other while loop has event structure that has several booleans which trigger different events. Both the while loops are operated using the same stop. My problem is this. None of the events get triggered when I press the buttons for them. However if I keep the stop value true( which stops the acquisition) and then click the event buttons all of them work fine. so every time I want an event to run I first change this stop value to true and then press the button for the event to fire. I want to know what is causing this? Why is th stop button influencing the behavior
of other events?

If your while loops are completely independent then it whould work. I've attached a simple example in LabVIEW 6.1 that shows a while loop with an event structure and another running continuously. A single stop button stops both but until then, the event structure will respond to clicking on two other Booleans in the VI.

Strange behavior of the notifications

Hi guys.
I use an iPhone 5S running iOS 7.0.3 and have a strange behavior of the notifications.
Example:
I get 3 messages from WhatsApp.
The lock-screen shows the preview of all 3 messages. OK so far.
But if I unlock my iPhone, a banner shows the latest message and the app-badge shows only 1.
This I have with other apps too.
This was not with older iOS versions
All settings looks OK. Do you have an idea?
Thank you, Tom

Because you are comparing floating point numbers.
For example 0.1 cannot be exactly represented in binary, so repetitve additions will probably not end in an exact integer later.
From the three inputs you can calculate the number of values exactly, and use a FOR loop. Don't use convoluted code....
Why don't you simply use ramp pattern?

Instrument driver development wizard strange behavior

Hi,
I was using the driver development wizard and I started getting strange results. It started creating VI's where the text builder portion ws seperate from the VISA communication portion of the code. I had to delete indicators and controls and wire the seperate sections. Also, the VI's dropped the VISA commands and replaced them with nonsense commands. Very strange. I closed and re-opened LabVIEW, but no change.
Has anyone had this happen to them?
Mark Ramsdale

Hi Mark,
That does seem like some strange behavior. Could you fill me in on some more information?
I'd like to see if I can recreate the issue on my end.
What OS are you running?
Version of LabVIEW?
Version of Measurement & Automation Explorer?
DAQmx Driver?
VISA Driver?
What were you trying to build a driver for? At what point did it start having issues?
Any other useful information you can think of?

Strange behavior when "trying" to burn a disk.

At least I think this is strange behavior, following the instructions in the help viewer, topic "Backing up your music to a CD or DVD." One thing for sure, it's not burning a disc and it ain't telling me why.
I select the playlist and click "Burn Disc"
Requests a blank disc. I insert one.
Message "checking media"
after about a minute, the disc ejects
Message "checking media" displays another 30 seconds
No other messages displayed.
What the ??? Shouldn't it at least display an error message??

Whoops, sorry, this was while burning a playlist.
I've also tried some Pleomax CD disks (Samsung), with no luck. I've tried burning directly from iTunes, and from Toast 7.
Of the types I've tried, the Sony DVD's have been the best for me. Haven't tried many types though. Maybe I can get disks one at a time until I find a brand my burner likes.
Still, isn't it strange that there is NO error message? It just quits?

Strange Behavior with gMSA in Server 2012 R2

Greetings,
I have been doing some testing with gMSA Accounts in a Server 2012 R2 environment (two separate environments, actually), and I have noticed something very strange that occurred in both environments, which does not appear to be occurring in one of our customer's
self-managed environments.
We created a Group Managed Service Account using the following article:
http://blogs.technet.com/b/askpfeplat/archive/2012/12/17/windows-server-2012-group-managed-service-accounts.aspx
Everything went smoothly, and the account installs/tests successfully on both of the hosts that we are testing on. I am able to set my services to run under the account, and most of them appear to work fine. I am having some issues with a few of my services,
and I believe that the strange behavior I am seeing may have something to do with this - described below:
As soon as I set the service's Log On Account (via the Log On Tab under the Service's Properties), the entirety of the "Log On" tab changes to "greyed out," and I am unable to change the Log On account back via the GUI (Screenshot
attached).
I found that I am able to successfully change the account via Command Line using sc.exe, but the Log On tab remains greyed out! So far, I have found nothing to remedy this, but confirmed that it happens for any service I set to use the gMSA as the Logon
Account, and that it happens in 2 separate test environments, but not in a Customer's production environment - very strange.
All servers in this environment are running Server 2012 R2, and domain Functional Level is currently Server 2012.
I have been unable to find any information online about this behavior, so I am hoping someone has seen this before, and can explain why this is happening.
Nick

VIvian,
Yes, we used the Install-AdServiceAccount gMSA command on each host using the gMSA account, and then ran Test-AdServiceAccount gMSA, which returned "True."
However, one thing I noticed is that if I run Test-ADServiceAccount gMSA as a Local Administrator, it fails with the following:
PS C:\Users\Administrator> Test-AdServiceAccount gMSA$
Test-AdServiceAccount : The server has rejected the client credentials.
At line:1 char:1
+ Test-AdServiceAccount gMSA$
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : SecurityError: (:) [Test-ADServiceAccount], AuthenticationException
    + FullyQualifiedErrorId : ActiveDirectoryCmdlet:System.Security.Authentication.AuthenticationException,Microsoft.A
   ctiveDirectory.Management.Commands.TestADServiceAccount
If I run Test-ADServiceAccount gMSA as Domain Administrator, it returns true:
PS C:\Users\Administrator.<domainname>> Test-AdServiceAccount gMSA$
True
Is this normal?
Overall, I think the issue I am running into is at the Application Level, and not a problem with the gMSA, as it appears to be working. (Can Start/Stop services without any issues). I will be investigating my issue further with 3rd-party vendors, unless
you think there is something wrong with my gMSA accounts based on the information I have provided.

Strange Behavior from iTunes 7.2

Running itunes - 7.2Recently had my itunes library “corrupted” or non functional.
Spent a long, long time rebuilding the library (see below) and noticed some strange behavior that has me terrified that itunes is corrupted and I am going to loose all the hard work, etc..
1. I have about 100 GB of music in various formats (apple protected/itunes store, mp3 (128 to 320), apple lossless, wav) and when I tried to rebuild the library by clicking on add to library it only added about 65 GB of the 100 GB. I had to go through and figure out what was missing and manually choose the specific folder when I added it.
Major pain and very time consuming.
So it is not adding songs correctly, but through way too much effort able to work around this.
2. About ½ of the itunes store tunes I purchased are no longer apple protected format. Somehow they were converted to mp3 at 192kbs. Some of the songs play fine others are now not as crisp and make a poping sound or skip. How could this happen? Are these files corrupted? Will I loose them?
3. At the top center of itunes the information bar, where the read out is for what song is playing and how much time has elapsed in the song, is not working. When I click on a song it starts playing but the elapsed time bar and counter never move, and when the next song starts playing the information never changes. It is stuck on what ever song you initiate play with by clicking on it and the information stays frozen.
4. itunes randomly stops playing at the end of a song….If listening to an album it is usually after three or four songs and when listening to a play list it is usually after one song.
I am afraid itunes is corrupted and will not function correctly and I am going to loose the hard work I put in trying to recover from the last crash.
Any suggestions??
Can’t wait for time machine. I hope it works as advertised. If so I could just go back in time to the last time iTunes worked correctly and go from there.

First of all I hope that you have a good b/u of all your tunes - either on ext HD or on DVD. Don't forget to b/u the iTunes Library and .xml files at the same time.
Have you tried to reinstall iTunes? Drag the app to the trash and remove the iTunesX.pkg from HD>Library>Receipts>iTunesX.pkg. Using a fresh .dmg of iTunes 7.2 reinstall.
Have you repaired permissions with Disk Utility?
Is your Quicktime up to date? At least version v7.1.5.

Strange behavior - icon thumbnail instead of image - CC@OSX10.10

Hi,
my CC (@OS X 10.10.3) showing a strange behavior using vanishing point filter.
After defining grid and try to paste the image OS X paste the icon thumbnail instead of the image,
Many thanks in advance!!

Joachim

It is probably related to the fact that you are setting the tables row height in the renderer this will fire a render message when the height changes. One height is applied to all rows of a table. This means that is you have images of different heights you are continually changing the tables row height and therefore continually rendereing.
My approach would be to have all the images fit into a set size ( say 64*64 ( with scaling if neccesary ) you could then have a popup show the full size image if required.

Any suggestions?

I am having the exact same problem(and no one is replying to my post either), I read in another post of someone who had a somewhat similar issue and someone commented that it was bad VRAM and warranted the logic board to be replaced. I'm hoping this is not the case, or at least hoping the problem does not get worse because I am in school and can't be without this computer for 2 weeks while it gets repaired..I'm hoping I can last til the holidays...

Strange behavior when I try to match a mpeg2 video with the menu size image

hello all,
got a strange behavior when I try to match a mpeg2 video with the menu size image,
menu size is 1920 x 1080 (photoshop file)
mpeg2 video 1920 x 1080 (1second 19 frames)
the idea is to go from the menu link to the next sub menu with a video as transition, using the same image on the video as the menu and then zooming in (in my case through a door) to end up after the zoom in the next level menu.
I try to achieve a smooth change from the first play menu picture to the video image into the next level menu picture,
everything works good but when I watch it on the preview mode on the left and right side of the video it shows a black bar at least 15 to 25 pixel wide, that means the video image appears smaller and it causes a little jump what is preety disturbing and can not be sold as a professional work.
why encore treats the video size and picture differently?
it's gratful appreciated if somebody who got experience in a transition I mentioned obove posting any solution,
thankl you all

Hi all
I'm having a very similar problem with Encore. My menu items are distorting (a minor but infuriating squashing top and bottom) when previewed.
Using Encore,PS,AE CS4
DVD format SD PAL DV widescreen
I created 3 menu frameworks and 3 video transistions to link them in AE. On the final frame of each transistion in AE I saved the frame with Composition>Save Frame to> Photoshop Layers. In PS i added the button functionality and saved.
In Encore I use Dynamic link to import AE transistions as timelines and imported each PS menu twice, once as "menu" and once as an asset.
When I link the timeline transistions to the menu and preview at the point the menu begins the whole image is squashed. When the next transistion is activated the image returns to its original size.
Thinking it was the use of PS that was causing the menus to distort I used the menu asset directly in the time line. Obviously no menu functionality but also no distortion. The AE transistion flowed straight into the "menu" just as I expected.
In the properties panel the menu Aspect Ratio 16:9
The AE transistions PAR is SD PALwidescreen 1.4587.
I did try the Blu Ray suggestion above but the same distortion was apparent.
Any suggestions short of squashing the video to match the menu would be welcomed.
Thanks

Strange behavior of textareas in BPEL Worklist (10.1.2)

I have a very strange behavior with linebreaks in all my <textarea>s in the BPEL-Worklist-jsps: (they work fine as <INPUT>s
Example:
Default-text:
line1
I update the textarea to:
line1
line2
-> hit update
line1
*** (second line is completly missing)
-> hitting update again (no change in text)
line2line1
*** (all on one line with the new line in front)
As Value I use:
<%=PayloadFormGenerator.selectNodeValue(payload, "/ns0:task/ns0:payload/ns1:abstract", form.getNamespaceMap(),"string", context.getLocale())%>
and as mentioned: It works fine for <INPUT>.
What do I do wrong? Is this a bug?

Strange behavior with Zoom and Image control

HELP - I have a strange behavior (bug?) with using Zoom
effect on an Image that has been placed on a Canvas. I am using
dynamically instantiated images which are placed on a canvas inside
a panel. I then assign a Zoom IN and Zoom Out behavior to the
image, triggered by ROLL_OVER and ROLL_OUT effect triggers. THE BUG
is that the image jumps around on the Zoom OUT and lands on a
random place on the canvas instead of coming back to the original
spot. This is especially true if the mouse goes in and out of the
image very quickly. HELP -- what am I doing wrong? Computer = Mac
OS X 10.4.9 Flex 2.0.1
Here's a simple demo of the bug -- be sure to move the mouse
in and out rapidly:

There must be bugs in the Zoom effect code -- I changed the
Zoom to Resize in the above code, and it works perfectly. Of
course, Resize is not as nice as Zoom because you can't set the
resize to be around the center of the image, but at least it works.
Does anyone know about bugs in the Zoom effect?
