Strange IMAQ Error Message: "ni: A frame has been dropped and the acquisition has been canceled."
Hello,
I am getting a strange error trying to use the NI PCIe-1427 with the MATLAB image acquisition toolbox configured with continuous acquisition. After about 5 minutes of acquisition, I get the error below:
??? ni: A frame has been dropped and the acquisition has been canceled.
Does anyone have any clues as to why I am getting this error / where I can find out what causes it? I need to acquire several hours worth of data and this error completely aborts my acquisition.
--Y
Hello,
Turns out that I found the problem. I had a slow memory allocation in my MATLAB code and this delay allowed too many frames to be accumulated in memory. I still do not know the source of the exact text of the error, but upon removing the slow memory allocation the error no longer occurs. I believe that it may have resulted from a buffer overrun of some sort in the underlying driver.
Given that this no longer poses a problem for me, I will not pursue it further.
Thank you for your help!

Error message: ni: A frame has been dropped and the acqusition has been canceled
I use a NI PCIe 1433 framegrabber with a Basler spl4096-140km line camera.
Using triggered acqusition with an external source, I can get a framerate of 68500Hz in NI-MAX.
When I use the Matlab image acquisiton toolbox to acquire data, I however very often get the error message: 'ni: A frame has been dropped and the acqusition has been canceled". This happens even at much lower framerates (20kHz) and only seems to go away when acquiring data slowly.
Computer is a Dell Precision 7600 and I assume there should be no issues with RAM or the PC being slow. The error does not go away when reducing the data size (i.e. reducing the ROI to one single point that is readout).
Do you have any pointers why this error message appears and what can be done about it?
Thank you!
RetoHello,
I encountered the same problem and I think it is because the allowcation of storage in matlab cannot catch up with that of the camera so that it will drop frames when the buffer is full.
I also want to know how to solve that.

My iPod touch is plugged into PC. My iPod is shown, but when I drag content from iTunes library to it I end up with an error message that says it "Cannot copy item" then "The device has either stopped responding or has been disconnected." What to do???
Yes you can drag and drop music to the iPiod if you select Manually Manage Music and Videos in iTunes.

You do not drag the music to put it on the iPod, you click into the iPod tab and sync it with your library.

I tried down loading mozilla firefox to use as a web browser. It was downloaded 100% then when prompted to "run" An error message comes up with a red cross and the message'This file is corrupted" and won't let me proceed. What do I do now?
It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox.<br />
You can try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.

I upgraded to 20gb iCloud but it isn't enough to back up. I get constant error messages saying there is no backup space and I've not been able to use the upgrade. Apple promised to refund then didn't. Please help is there anyway I can use this space?If you were told they would refund the price for the iCloud storage - Contact AppleCare and ask to speak with a senior advisor. Have the case number for the promised refund available.
If you are trying to update your device, but you don't have sufficient space to download and install the update, you need to delete content from your device. Buying storage in iCloud does not add space to the device which is what you need.
You can always update using a computer with iTunes installed - this method is faster, and will allow you to make a backup on the local computer (Local backups restore faster than iCloud backups).

I trying to download a book as a pdf to view through my adobe reader. But every time I do I keep getting the same error message saying that the file is not a supported file type or because the file has been damaged it can't be opened or viewed. What do I do and how do I get it to work. Because as of now I only have one option of downloading the book and I've tried to download the app notable pdf to see it that worked but it didn't either. As of right now I'm using google chrome but I also tried using Safari but it's still not working. I have a Mac with a Mac OS X updated system. I need an answer ASAP. Can anyone help me?
I have the same issue. Almost none of the PDFs I download from Safari browser can be opened. Same message about the file being damaged or not really a true PDF. Neither of these are the issue here. Size of file is not an issue. I have Acrobat Reader XI so I believe that's pretty up to date. If I open with Text Editor the file is blank. any ideas?

Received error message when updating to 1.1.4 and no IPT has nothing.
when updating to 1.1.4, received an error message and now my IPT looks as it did when i bought it and before setup. itunes doesn't recognize it to restore it. what can i do?
What error message did you receive?
Your best bet is to go to add/remove and uninstall Itunes, Quicktime and the Apple Mobile device and then reboot and download the latest Itunes and install it and Quicktime again. (if you purchased the Apps make sure to do a backup of the file iPod touch App Pack 4A93.ipa and you may also want to backup your Itunes music account as well)
Once you've backed up and re-installed everything and made sure it's up to date then hook back up your IPT and try and restore it. If that doesn't work then have a look here http://www.apple.com/support/ipodtouch/
You may also want to make sure your IPT is plugged into a good USB2.0 port such as the one on your motherboard and not the one in your front case. You should also disconnect any other USB devices execpt for keyboard and mouse just incase they are interfering with the IPT.

Sign in, activation, or connection errors | CS5.5 and later
For anything else you have to be more specific. you have not provided any system information nor told us, what the error message actually is.

My old email was hacked and since then my passwords have been changed. I have a new apply ID which if fine, but my phone is asking me for my old apple ID password before I can delete it from my ICloud. The problem is I cant reset the password and my birthday verification isnt working. I am unable to do anything in icloud because it is forever telling me my password is wrong. my new apple ID seems to be working on every other part of my phone. Any ideas what to do?
Well you can try this, but I'm not sure it's going to work if this is an entirely new ID.
Go to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Tap edit next to the primary email account, change it back to your old email address and save the change. Then edit the name of the account to change it back to your old email address. You can now use your current password to turn off Find My iPhone on your device, even though it prompts you for the password for your old account ID. Then go to Settings>iCloud, tap Delete Account and choose Delete from My iDevice when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address and iCloud ID name back to the way it was. Now you can go to Settings>iCloud and sign in with your current iCloud ID and password. -
