Writing to the file trigger event time

I'm new to LabVIEW.  I was changing the acq_graph_voltage_dig.vi I found to trigger recording using a digital triggering with a defined number of pre-trigger and posttrigger samples recorded.  I added screws to open, write and save a file of PDM with these data.  I want to be able to record when the shutter actually, produced as a separate channel or just as a landmark event when the trigger has occurred in the file.  I know that I understand that based on the number of sample pre-trigger, but it is something that I will probably change that I record.  I have only a single trigger per queue.  Someone at - it suggestions on how I could save the instance to trigger?

Thank you!

Hi shelby,.

I guess you want just the timestamp of when the trigger has occurred and then you will write this value to the file. If so, you can change the position of reading for relaxation of reference, read a sample and record the timestamp of this sample at the end of your file. A photo below as well as a version of the VI that you use. I add no IO files in the example as I assume that you already have this understood part. I hope that helps!

I looked at all the research sites and assistance, and none of them helped me with these problems and im getting ready to launch her aspire one mini laptop computer. im running xp and I bought it used and it has done this from day one. 2 weeks ago, that I got it. Please can you help me.

    How can I fix excerpt: error writing to the file C:docume~1\user\local~1\temp\nsvc.tmp\conduit-left.bmp

    and im having problems with my connection remaining on the port wireless what do I do, I can solve this problem too because I cannot even be in line for more then 5 minutes with the duty to stop and start over or repair the connection.

    For the first question, try to go to start | Programs | Accessories | System Tools | Disk Cleanup and that should clear of junk.  Then click Start | Run and type msconfig and disable the startup items, that you don't need, as many programs decide that they must run at startup and clutter the machine when they do not need to.  Also perform a defragmentation of the disk (under system tools also).  See if that helps with performance and other issues.

  • I need to know the file current date/time number stamp and the version of "spoolsv.exe" in Vista Home Premium 32-bit with SP2.

    I need to know the file current date/time number stamp and the version of "spoolsv.exe" in Vista Home Premium 32-bit with SP2. My spooler file got corrupted and I need to know what that the stamp of date/time on the latest version of the file: spoolsv.exe. I did a search on my hard drive and found 8 copies of the file with 7 different dates. I need to know which copy in my file C:\windows\system32\. I suspect that the problem was caused by some kind of malware. I think that some of the different versions on my machine of the initial installation of the Vista, SP1 and SP2. 3 copies that would explain. I tried all the suggestions in this forum and several others. I tried sfc/scannow and it simply replaces the corrupted file by another. I understand how works this file and a simple copy will do the trick if I knew that the file to use. I know that I don't want to go back to the first version of 2006.  BTW... my symptoms are all my printers have disappeared, and when I try to 'add a new printer' I get an error message saying that my spooler service does not work. When I opened my services window it shows that indeed, he is arrested, but I will not start because the description column contains only the code garbled machine indicating that the file is corrupted, or it may contain a virus. I had been using F-Prot until this virus got by and now I use AVG. I scanned my machine with several cleaning packages and it is is more infected, but I worry that from this corrupt file grow something. I know that the problem is not with my printers or drivers, because everyone on my home network can print on all of my printers. None of the people I know are on Vista 32 bit. They are all running System 7 or XP. I have XP, except that a few years ago I suffered from the "Syndrome of Pepsi" on my laptop and when I bought a new HP, it came with Vista.

    Is the drive in FAT32 formatted accidentally? If so, you can only restore up to 4 GB for a single file. Try to make a TIFF sequence instead. Tip of litte - press the LZW compression checkbox in the options for a lossless compression format, this allows you to keep the path file size down.

  • 1310.error error writing to the file for CS2 install Win7 for Adobe Pro 7

    I have Adobe 7 Pro to be installed on a machine Win7 which is not supported by Adobe.  They provide a CS2 version with a new serial number for replacement of my product since my product cannot be activated anymore.

    When I try to install it, I get the following error after started the installation process.

    1310.error error writing to the file: C:\Program Files (x 86) \Adobe\Acrobat 7.0\Active X\AcroPDF.DEU.  Make sure you have access to this directory.

    I am the admin of my machine and I also tried to install their version as the admin as well.

    Any help to get through this?

    I wasn't able take the permissions of the folder Active X using one of the recommendations no matter how I tried to change the permissions.  Activa X file for some reason any was locking me even if I am the admin.  There were four files that were already saved in the folder as part of the installation process that was able to complete before my error popped up.

    A work around that worked for me is that I have renamed this file active X_old - I have at least managed to rename the folder, even if I was not able to change its permissions.  I created a new Active X folder and copied the four files in the original in the new.  I've then restarted the installation process, and it went through.  It seems that I have all the features of the Adobe 7 Pro.

    I had a similar problem where After Effects, Premiere and Sony Vegas could not create QT files on some readers. After a lot of forum search I finally found a solution thanks to a tip from Rob Maybury on CreativeCow.net

    It seems that QT will write only to readers with a unique name. My volumes have been implemented as follows (to search in Windows Explorer)

    • Local disc (c :))
    • New Volume (e :))
    • New Volume (g)
    • New Volume (h :))

    I could create files in C: and F:, but not in G: and H:. After changing the Volume names so they were all unique:

    • Local disc (c :))
    • Volume (e :)) SSD
    • Master volume (g)
    • New Volume (h :))

    I could now create files on any drive.

    To change the name of the Volume, right-click on the drive and select "Rename" or display the Properties window and rename here.
