Is it possible to access channels on a DAQ board while the device is used by another application?

I am curious if is possible to run an application that reads one channel of a DAQ board while another application already is reading different channels on the board.

Shoe,
You can have more than one application accessing a DAQ board at a time but not for the same type of process, such as analog input. I tried a setup where one program was accessing analog input channel 1 and a separate program was accessing analog input channel 2. Only one program would run at a time. However, you can have an analog input program and a separate analog output program accessing the same board running at the same time.
Hope this helps!

"Your photo library is either in use by another application or has become unreadable" How do I regain access to iPhoto. All I get is an instruction to "quit"

When accessingh iPhoto all I get is "Your photo library is either in use by another application or has become unreadable" How do I regain access to iPhoto. All I get is an instruction to "quit"

Hi LarryHN,
I was loading images via a flash memory card which was inserted into a USB holder – during the 'download' the connection was broken [faulty USB connection]. I then re-inserted the card via the USB holder the connection was 're-broken' with a screen message indicating that 'force eject' was an option. I clicked the 'force eject' option and when I re-inserted the card/holder 120 images [approx] were missing and when I tried to open iPhoto the screen messages detailed above were displayed.
Current software is: iPhoto v9.2.3; Snow Leopard v10.6.8.
Using TD's Option 1:
i.e. “hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database” resulted in .
"Your photo library is either in use by another application or has become unreadable" with a window request “quit”
& Option 2 “Download iPhoto Library Manager and use its rebuild function”.
Resulted in the following message:
“The library could not be loaded because an error occurred. The library database could not be loaded; no such table RKVersionFaceContent. The album data file for the library 'iPhoto Library' could not be read” - [my italics]
Followed your instructions, re. 'new library' and it worked perfectly. All I have to do is select 'iPhoto Library2' and proceed as normal.
Thank You very much for your excellent advice and solution.
p.s. And this is completely 'off the wall' as I don't expect a positive outcome, but is it possible that all the images 'deleted' from my flash memory card could be somewhere in/on my HDD? If so, how would I proceed to recover them?
Many thanks again.

TS1393 I cannot eject my iPod using either itunes or the eject button on bottom tool bar beacuse it says something is in use by another application or "The device 'generic volume' cannot be stopped because a program is still accessing it" Synced new iPad

How can I eject my ipod when neither itunes not the "safe to eject" button will allow it. Itunes says "...cannot be ejected because it contains files that are in use by another application." The safe to eject button says "The device 'generic volume' cannot be stopped because a program is still accessing it." The has never happened before. The only thing new is that I added an iPad yesterday. Thanks.

Go to your computer's System Tray and try ejecting. If you can't eject, there is an application that is trying to access your iPod.
Go to http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx and download ProcessExplorer.
Go to http://support.microsoft.com/kb/555665 and follow the instructions under Resolution.
Note that this is a good, general process any time you can't access any file.
In my case an update to RealPlayer installed a program called RecordingManager that was accessing my iPod.

I was editing photos in my iphotos and it says Your photo library is either in use by another application or has become unreadable on me. I shut down my computer and when I restarted I can not access my photos, it keeps giving me

I was editing photos in my iphotos and it froze on me. So I shut down my computer and when I restarted I now can not access them. It says Your photo library is either in use by another application or has become unreadable. What can I do to fix this?

What you're describing is the Finder window for your external hard drive. When you're in iPhoto and try to edit a photo what happens?
Are you saying that the photos for your iPhoto library are located on the external HD while your library is in the Pictures folder on the boot drive? That would indicate a referenced library. You can check to see if you're running a referenced library by checking the Advanced Preference pane in iPhoto:
Click to view full size
So based one the Advanced preference pane in iPhoto what type of library are you running. Where is the library itself located? It should look like this:
By default it should be located in your Users/Home/Pictures folder. However, it could be run on an external HD.

How do you fix this error? Can't access photos Your photo library is either in use by another application or has become unreadable

How do you fix this error? Can't access photos----" Your photo library is either in use by another application or has become unreadable"

Try this: launch iPhoto with the Option key held down and create a new, test library. Import some photos and check to see if the same problem persists. If you can create and use a new library then your current library is damaged.
If that's the case make a temporary, backup copy (if you don't already have a backup copy) of the library and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Is is possible to access channels from a CAN database in labview with NI USB 8473s

Hello,
I would like to know whether is possible to access a CAN database, which is uploaded through MAX, in labview.
More specifically, I have uploaded my CAN database in MAX and I want to have access to each specific channel in labview.
i.e according to picture, I would like to have access to n_Motor_InsRpm channel of E1_L0_1 (motor speed) in Labview, so I can set and transmit a speed value through CAN. Could that be possible with NI USB 8473 s? If yes, is there any simple example in Labview ?
Thanks for your Help

There are several ways to get database information without needing hardware. Here is one I did a while ago.

I can't get rid of a "Not Enough Storage" pop-up on my IPad2. Can't close it and can't access settings. Can't shut off the device either. It's just locked up. What can I do?

How can I get rid of the "Not Enough Storage" pop-up on my IPad2? It won't go away, I can't cancel it, I can't access settings, and I can turn off the IPad to reboot. It is just locked up.

Reboot the device.
Shut down the device by holding the sleep/wake button and the home button at the same time.
Hold them both until you see the screen go black. In some cases, you may need to keep holding them even after the red power off slider appears. If it does, just keep holding it.
Wait until the white Apple logo appears.
When this happens, you can let go - the iPhone is rebooting.

Scan AI from all channels in 6023 daq board

I am trying to use single point scan for every Analog input channel in my 6023 board. I get a scan out of range error. I have tried multiple configurations. Basically it is only letting me scan 9 out of the 16 channels. I am scanning 0-5vdc signals. I have even tried the multiple channel scan with the same error.

You will get a scan out of range error if your board is set for differential instead of single ended configuration. Find this property in MAX.

Error -50103 when I am trying to access two channels on USB 6366 board in the same time

I am trying to use two DAQmx tasks attempting to access two channels from
USB-6366 in the same time. But it gives me an error Error -50103. So I looked
online and find out it says ' It is not possible to have multiple DAQmx tasks
attempting to access the same physical device. '. So I am wandering how can
collect data from my ai0 and ai1 channels in the same time? Here is my code,
and please help me out. Thanks very much

Simple - use a single task with multiple channels. Surely the answers in all of the related posts said that. The channel list is just dev1/ai0:1.

Possibility of Apple TV playing one Itunes Library while the computer plays a different library at the same time (Mac)

The Apple TV is for my son's room to watch his videos, listen to music, etc. off his iTunes library I made for him on my Mac. I want to be able to listen to my own library at the same time he has his. Apple TV only recognizes the current library open; unless I'm doing something wrong or the stars haven't aligned for me yet, is there a way to do this? I can't run two iTunes at the same time (wish I could).
*Note- to teach my son about computers, I bought an old green iMac which will be for his learning venture. The iMac however does not have wifi (at least not yet). Perhaps something for you Mac professionals can use to help me whip up a good setup, unfortunately the iMac is slow, not enough HD space, so I don't have the funds right now to open it up and do what can be done. (If this helps)

Hi All,
Same issue here. Just upgraded (?) from the previous version of Apple TV, to the new Apple TV2. Like others here, my main problems seem to be with unreliable streaming from iTunes 10 on my PowerMac (Quad G5, Leopard OSX).
My original AppleTV had no issues w/the wireless network, or synching w/my PowerMac.
The network connection from the ATV2 are fine, and have no issues accessing the Apple Store (for movies, TV shows), or accessing Netflix. The access to the internet from my ATV2 is quite robust.
My problems are with keeping a constant, reliable wireless connection to my PowerMac, via an Airport Extreme wireless router.
I have tried multiple restarts, reboots, reset ATV2 to original settings, tried different wireless channels on the Airport Extreme, verified I have Home Sharing properly enabled in iTunes,etc, but no luck so far.
What I'm seeing is when I access my iTunes on my computer, I can see my library, and then if I start to "shuffle songs" I may get 1 to 3 songs to play fine, but then the music stops, and I can no longer access the music/movies/etc in iTunes any longer. When I then go to my PowerMac, it has lost most bars of signal strength on the wireless network (although all other devices show strong signal strength), and I have to Turn AirPort Off, then Turn AirPort On and I then am reconnected to the wireless network with good signal.
I then go back to the ATV2, connect to my iTunes, start my music, and then 1-2 songs later it again stops playing, and I go through this all over again.
It seems as though there is something on the wireless network between the ATV2 and my PowerMac that causes it to lose connection, and I have to manually start again. The problem is that the connection is not robust, and only lasts a few minutes.
Hope this gets solved soon.
Regards
Tom

Is it possible to store data collected in a form when the device is offline?

I am trying to figure out if this is possible. I want to collect email addresses via an interactive PDF when offline. ie. have a text field and submit button which would save the data to the pdf or an associated data file - txt/csv etc? Is this possible or just wishful thinking? as an alternative, is it possible to have the PDF send the data once it reaches an internet connection.
I have a feeling I am asking too much of the multitalented PDF on this occasion.
Can anyone help?

Hi,
If you are using FormsCentral Web form then, no. You could use a FormsCentral PDF form; however, you will have to save each PDF form that people fill out locally (with a different filename) and then when you are online open each form and submit the responses.
