Vision acquisition express stalls when i select a camera even if i click 'refresh'

The vision acquisition express stalls when i select a camera even if i click 'refresh'. Using Labview 2010 (evaluation) on a Windows 7 laptop and tried on another computer running windows xp.

Hi,
A few questions:
1) What kind of camera are you using? (what model, are you using IMAQ, IMAQdx, what version, etc.)
2) Are you able to acquire from your camera in MAX?
3) can you run a shipping example using the low level VI's or does this only happen in Vision Acquisition Express?

Saving Images Using Vision Acquisition Express

I'm trying to save an Image as a jpg using Vision Acquisition Express. My code looks like this. I am able to view the images and scroll through them afterwards, but when I add the file saving portion, I get an error that says "Error 1074395995 occured at IMAQ WriteBMPFile File not found."
How should I go about Fixing this?
Also, when i was running this before, I was getting a memory error and I couldn't figure out how to clear the memory. I was only able to fix this by scraping my previous script and starting over. I haven't gotten this error so far.

Hi,
The error you are getting indicates that the file path is invalid. I just set the file path to my desktop and I could save the files. I would double check to make sure the path you specified is valid for the computer you are running it on.
As far as the memory error, it is really hard to say what the cause is. If you aren't getting it anymore then I wouldn't be to concerned.

Vision Acquisition Express VI error

Hello
I am new in labview and I am using the Vision Acquisition Express VI in a while loop. When I run the code, I get an error message " NI-IMAQdx: (Hex 0xBFF69004) Invalid camera session".
Please help me

Which iteration? If it fails from the very first its likely that the express VI is not configured correctly. If it fails on subsequent iterations there might be a problem using the express VI in a loop (never use express VIs inside loops).

Vision Acquisition Express vi stopped working

Hi everyone,
The Vision Acquisition Express vi always worked perfectly on my pc, but suddenly, he stopped working today (I can drop it on the block diagram,but there is no pop-up or something,
I tried the following:
- restart pc (didn't help)
- try other express vi's (including other vision express vi) (worked fine)
- convert it to normal vi (empty vi as result)
- open properties with rightmouseclick (didn't help)
- open an example en doubleclick and rightmouseclick properties (didn't help)
Anyone an idea??
Best Regards,
Henk

Hi Henk_kempen,
This is really weird. Do you know what has happened to the VI/PC before this happen?
There are some troubleshooting you can try.
1. This problem really close to DAQ assistant issue in this white paper. You might try the method in the link below to see if this solve your problem.
http://digital.ni.com/public.nsf/allkb/5CD79190713D2B558625765F007FCC99
2. Repair the software is another option. It worked in many cases.
3. I try to avoid this but reinstall the software may help in your case.
Best regards,

Joanne Murray J2 What version of Premiere Elements are you using and on what operating system (including 32 or 64 bit) is your Premiere Elements installed? Forgive the questions if you have been there and done that, but I do not want to take anything for granted that might hinder a speedy resolution to your issue. Are you opening an already created title that is sitting on the Timeline in order to edit it in the Titler or are you trying to create a new Title (Default Text or other)? Do you know how to work with the Selection Tool and Type Tool in the Titler? Once I know what version of Premiere Elements that you are using, I will give you specific how to details. Thanks. ATR

Best to install them one at a time, re-booting between each one.

Clip inspector in imovie not working properly - when I select a picture - and select clip adjustment it tells me that I need to select one or more clips to view Inspector tools and in a clip the audio adjustment only shows a speaker? help

Clip inspector in imovie not working properly - when I select a picture (in project library) - and select clip adjustment it tells me that I need to select one or more clips to view Inspector tools and when I select a movie clip and then click on audio adjustments the audio adjustment appears as a speaker icon and I don't know how to get to the various audio options? It was working fine one minute and then I seemed to lose the functionality. Also editing a photo in a photo or getting rid of ken burns effect etc does not seem to work. help

Can anyone shed any light on this as I am having the same problem? One minute it works fine, the next you get the error message above.
Many thanks.

Lumia 620 option to select front camera has vanish...

Noob here so go easy on me, tried searching but couldn't find anything...
My Lumia 620 seemed to spend most of the weekend updating various things including windows 8.1 cyan. now when I select the camera function I haven't got the option anywhere to select the front camera. When I start the standard (Microsoft?) camera app either from the apps menu or by using the camera button I just get a choice of Video, Burst and Single Photo modes across the bottom, tapping on ... brings up photo and video settings but no option anywhere to change to front camera. The rear camera seems to work fine.
Is this likely to be related to the updates or could something else be up (I haven't tried to use the front camera for a while).
Any suggestions appreciated.
Solved!

Everything's simple when you know it/how to
From within the camera settings, you can also change default camera app if you've installed other ones. The Nokia camera app and Nokia panorama app are free apps to concider if you like taking pictures

Vision acquisition on TPC-2512

hello,
I designed code to grab video from an IP camera using IMAQdx and deployed it on a TPC-2512, the app run well but the Image Out shows black screen.
When I run the code on my laptop it works fine (the laptop and TPC are both targets in the same project) and i can see the video from the camera on the TPC using the web browser and when using IMAXdx example app and it also identified on MAX so it's not a connectivity issue.
I also tried to use vision express vision aquisition instead of IMAQdx and it worked on the laptop but not on the TPC (shown black on the image out).
I used LabVIEW 2011 to design the VI on the laptop with NI IMAQdx 3.8.1, the TPC works with LabVIEW Run-time 2011 and NI IMAQdx 3.5 so it might be the problem. The camera I use is AXIS 206 and i enabled free access without password.
I attached a picture of the block diagram.
thanks, Daniel.

Daniel,
Unfortunately vision acquisition software is not officially supported for Windows XP Embedded. However since all you want to do is display the image, a possible workaround would be to acquire images in the host VI then use network streams to send the images to the Touch Panel to display. Here is a knowledge base article that describes how to send images over network streams. I hope this helps.

Dont use express vi. Use imaqdx open outside the while loop. Use a snap inside the while loop and use a close outside the loop.

Classic freezes or stalls when started in OS X 10.4.6

Hello,
The classic environment freezes or stalls when it is started from OS X 10.4.6. In the expanded classic window pane, the smiling mac on the grey background appears, then the "welcome to Mac OS" appears (Mac OS 9.1). The blue progress bar at the top shows only a small sliver of blue on the left, and the progress bar does not advance at all. After many minutes, 10 or 15 so the classic window closes, perhaps a time-out limit, and has not started.
Mac OS X 10.4.6 was just recently installed on our Mac G4 from CD (4 CDs) rather than the OS X DVD, since we only have an internal CD drive. Our Mac is a 733 MHz PowerPC G4 (2.0) with 1 CPU; 512 MB SDRAM, 1 MB L3 cache, and 32 GB of available disk space. Let me know if other details would help with a diagnosis.
I have tried the suggestions given in the other forum articles that talk about the classic envirionment freezing or stalling such as:
blessed the Mac OS 9.1 system folder,
rebuilt the desk top,
removed the OS 9.1 servers folder,
turned off extensions in the classic options,
disconnected all external devices,
searched for the DivX folder, but didn't find it.
Are there other things I should try to permit classic to start from OS X?
Other forum articles seem to indicate that starting up classic in OS X allows older software to run in OS X. Is that true, or am I missing something?
By changing the start up disk to OS 9.1 the Mac will boot up directly to OS 9.1 (the previous OS used for many years) without any problem. Our current work around for older applications is to change the start up disk and boot up directly to OS 9.1.
Your advice and help is appreciated. My goal is to be able to start the classic Mac OS from OS X to run old applications like MS Office. Thanks for your help.
Regards,
Greg
Mac G4 Mac OS X (10.4.6) classic freezes during start up

Hi Robbie,
Thanks for your reply to my question. I'll try to describe how I start classic in more detail. I have tried starting classic from the top menu bar icon (and from the classic system preferences form), and by trying to directly start an OS 9 application (like Word or Excel).
When I launch classic from the top menu bar icon a new window opens with the "smiling mac" on the grey background followed by the "welcome to Mac OS". At that point nothing else happens for a long time (no progress bar movement, no other forms or windows opening), in excess of 10 to 15 minutes. If the classic form closes after the long wait, the classic system preferences form still has a "start" button, so I presume that classic has not started. OS 9 applications do not start at that point. Should the progress bar move while classic is loading? I'm pretty sure that the blue progress bar in the classic window never moves, even when the classic window closes.
When directly opening an OS 9 application like Word or Excel the classic window opens, but again no change to the progress bar and the classic window stays open for a long time. The OS 9 application does not start.
Does this description help? Let me know if I can provide more details of what happens. I would be glad to try any tests you suggest, and report on the outcome, to help diagnose this problem. I can also try upgrading to OS 9.2.2; can you point me to an easy way for that upgrade? I'll check around the apple web site too.
Since the Mac can be booted up directly to OS 9.1 or OS X (by selecting the startup disk) it seems like there may be something that is interfering with classic being launched from OS X. Perhaps there are other files or preferences that can be disabled or removed in hopes of removing the interference and gettting classic to launch?
Thanks again for your help with this classic start up problem.
Regards,
Greg

Case expression error with a select query in the condition

Consider the two query below:
1. The first one use a case expression :
select case when 3 > (select 1 from dual)*2 then 1 else 0 end from dual
2. The equivalent with a decode expression:
select
decode(sign(3-(select 1 from dual)*2),1,1,0) from dual
The first query return an ORA-00905 error but not the second one. It seems that the arithmetic operation (select 1 from dual)*2 cause the error. The folowing query doesn't return this error:
select case when 3 > (select 2 from dual) then 1 else 0 end from dual
I run the test with Oracle 8.1.7.3 Enterprise Edition. Is it a known bug ?

Open cam VI in Main.exe and Vision Acquisition License

Hi,
I've an application which controls some devices...I've two questions:
1. I'm building an exe of my main VI. When I run it as exe on other PCs, it doesn't open the subVI (cam_pos_test.vi) (on my PC is everything running ok). The cam subVI is added in the always included VIs, when I build the application. Part of the main level VI looks like this (control/producer loop):
in the red circle is the subVI which opens the Ref to the cam_subVI. It looks like this:
I think: I make some error in the defining the path of the subVI (cam_pos_test.vi). Do you have some idea, what could be wrong? Why the cam_pos_test does not pop-up as it should on the other machines? :-) I've tested the cam_pos_test.vi as exe is running on other PCs.
2. I've Vision Acquisition License on my PC. Do I need Vision Acquisition License also for the PC where the executable is running (to use a cam)?
Thanks!
Angel

Hi,
I've LabVIEW 2010 Prof. + Vision Acquisition License on my PC (where I write the code). To check: is the problem in the source code or in the executable, I've used an evaluation version of LV2010 on another PC ... as a VI it runs without problems on the lab PC, but as an executable it runs but doesn't open the cam window :-( (everything else is ok)
The code of the cam.VI is attached. I've used only IMAQdx VIs to obtain an image from the cam...
Thank you for your time,
Angel

Vision acquisition not reading avi file

Hi-- I am currently running LabView 2010 (version 10.0f2) to run the Multi-Worm Tracker (http://sourceforge.net/projects/mwt/).I am currently using the Vision Acquisition Software evaluation version, though I do not have any image acquisition hardware or camera connected; I am only concerned with running AVI files. Everything seems to work perfectly except the program does not appear to "see" the file, even though I am able to select it upon opening without issue.
It appeared to me to run and track images the very first time I ran MWT, though I was not able to see the video at the time. However, it has not worked since that first time. I am curious if anyone out there has thoughts on:
1) Whether or not it is the vision acquisition software that is responsible for this problem
2) If the evaluation version only works once (seems silly as it is good for 30 days... 28 now)
3) What I might be able to do to troubleshoot this
Thanks for your help,

-Sorry no info on how you are reading avi file?
-It is just an exe. That too looks like it needs lot of other dependencies.(Or am i missing anything??)
-If you need to clarify your doubt on Vision acquisition, just use one of the inbuilt examples in labview for reading avi files and then proceed.
-No, i think evaluation version works untill evaluation time expires.
-You need to provide the code not exe to troubleshoot on more.
Thanks
