Datalog writing can only add and not replace plug

I noticed that writing Datalog function only adds data to an existing datalog and has not replaced the record set by Datalog set position. It is very strange, is this normal or I missed something?

Hi Zigbee1,

According the context help on LabVIEW, the function Datalog Write "sets the current position of the datalog to the end of the file before writing".
He explains also in the link below that you cannot replace a record after LabVIEW wrote in a datalog file.

    Try Firefox SafeMode to see how it works there.

    A way of solving problems, which disables most of the modules.

    (If you use it, switch to the default theme).

    • You can open the Firefox 4, 5, 6, 7 SafeMode pressing the SHIFT key when you use the desktop Firefox or shortcut in the start menu.
    • Or use the Help menu option, click restart with the disabled... modules while Firefox is running.

    Do not choose anything at the moment, just use 'continue in safe mode.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before using the shortcut of Firefox (without the Shift key) to open it again.

    If it's good in Firefox SafeMode, your problem is probably caused by an extension, and you need to understand that one.

  • How can I add and synchronize groups and AD users after a successful installation?

    Hello

    Maybe I don't see the wood from the trees.

    I have successfully installed a working environment of the Horizon.

    Now, I would like to add a few new users and AD groups, so that they would be synchronized with Horizon Workspace.

    If I am logged on as admin-account on the portal of the workspace, and I can see the tab "users and groups".

    There, I also see synchronized users during the installation, I added.

    But how can I add and synchronize the users in my ad?

    Kind regards

    André

    AD synchronization is done automatically on the schedule that you specified during the Setup installation ad part. You can change it and thus force a manual synchronization. But it is done on the connector and not the ordinary administration portal. You access your connector by using https:// Connector_URL:8443

  • Why I can't run my Lightroom 6 (not CC) after that I use it only once? After a reboot (7 Wi\ndows), I can only use and closr LR once. This is after I did a recent update.

    After a reboot (Windows 7) I can only use my Lightroom 6 (not CC) once. It will not start again. This happened after I did an update. I can not even find the program id in my Windows Explorer. Al; so, I visit the Web site and see that I have a license for the program, but it can not load again. Why not?

    I have experienced the same problem and advice from Adobe fixes it-

    If Lightroom remains present in the task manager then try this procedure.

    Procedure-

    1. Make a restart/re-start computer
    2. Open Lightroom
    3. Open the Task Manager. (CTRL + ALT + DELETE)
    4. Right click on the App - Adobe Photoshop Lightroom-
    5. Select "see details" «
    6. Right click on "Lightroom.exe.
    7. Click on "set priority".
    8. Set the priority to 'high'.
    9. Close the Task Manager.
    10. Close all programs and restart the computer
    11. While you open Lightroom - reset the preferences by pressing [SHIFT + ALT].
    12. LR control closes correctly.
  • Download files, download only once, do not replace the old same files

    Hello

    For our company, we work with many files on firefox.

    On a computer, when we download a file (Open Office), it does not replace old file, we downloaded before. The system adds (1), (2), on behalf of the end of the file. When we have to save this file, we have so many files for the same thing but with several versions.
    In the Options, I checked that Firefox always ask for the download location. And enforcement, asking for all Open Office files.
    For other computers, there is no problem.

    Thank you.

    I think that, by resetting download action, can solve your problem.

    To reset all the how many files types are managed by Firefox, return to the default value:

    Open your profile folder:

    First, at the top of the Firefox window, click on the Firefox button, hover over the menu help and select troubleshooting information. The troubleshooting information tab will open.
    Then, in the Basics section of the Application, click Show file. It will open a window with your profile files.

    Then, at the top of the Firefox window, click on the Firefox button and then select leave
    Then, rename the mimeTypes.rdf file to mimeTypes.rdf.old.
    After all, restart Firefox.

    For more information, you can see this article to change the parameters of type file

  • Replace Footage - limits: no [Cancel] and not [replace the multimedia browser]

    Unless I missed something (quite possible)...

    It would be good to see the following improvements to the first CC:

    • [Sequence replace] must be included in the list [Cancel].
    • [Replace with the selected item in the media browser] to add as an option when you replace a component in the [project] pane.

    Why is it useful:

    For example: I started with a timeline of first CC images XDCAM EX clips.   Images XDCAM-EX requires careful treatment because it's based and calibrated, largely as AVCHD file structure.  To get these images correctly in the first, it is necessary to use the media browser and not simply to drag in files 'essence', namely [.mp4] files (within this file structure).  It's ok to drag it from the media to the component of the project browser, because this operation recognizes all relevant information in the file structure, a unique at the highest level clip that matches more than one file [.mp4], maybe extends on back.  This method saves the user details.

    OK so far

    Then, I chose such an item in the projects pane and [clip > RightClick > replace footage] him substituting an improved copy (which was a [.avi] file encoded using the Cineform-GoPro "visually lossless" codec).  Which is very successful.

    If still ok.

    But then (as dark clouds gathered...), complete experience, I tried to [Cancel].  But he didn't... cancel the [sequence replace] that is.  Doesn't seem unreasonable for me and certainly not convenient.  Imagine in real life, if only after a replacement that some problems with the replacement film was noticed (or, hypothetically. If the first treated in some unexpected way).  Any undo!   Gah!

    Workaround is not simply a matter of fact another [replace sequences] in the part of the project, because that opens a file Explorer, there no option to use the selected item in the media browser.  Also it is not possible to select the original film of XDCAM-EX appropriately, only a single file such as the file of gasoline [.mp4].  And it would be a bad idea, especially for a clip split (on several files [.mp4].  Hmm...

    That let him bypass clunkier to reimport the original film via the media browser, so it appears in the part of the project, then by selecting, then down to each individual instance of it at the level of the timeline, and in each case [replace with clip] from [bin], that is, the original footage in the project pane.  In addition, while all the metadata (for example "newspaper Notes") on the original (before replacing) item be transferred to the replacement sequence, that the metadata are not "inherited" from fresh importation of the same origin of the film, so if necessary then it must be entered or copied manually on the whole.  Ugh!

    Thus, improvements to the first proposed at the beginning of the year would be a good idea?

    However, when I clicked on [see] it has a fresh window, who acted as an ordinary file browser, not as the appropriate media (part) browser.

    Hmmm.  Show me, post a screenshot.

  • How can I add annotations (notes, in particular) as a PDF in preview of El Capitan?

    I have a PDF file and I am trying to annotate, and I do not understand what to do. This is a test of the student, and I would like to add comments in the PDF file.

    All I want to do is click on the PDF to indicate a comment at this time, and then type the comment so I and the student can be seen in the sidebar, but it seems to me to miss something fundamental about how to make this work (wasn't that easy a couple of versions ago?).

    What happens now: the PDF file is opened. I open the toolbar of the Markup (by the way, can I have that open by default?). I move the pointer to the place where I want to add a comment. I press Ctrl-command-N, and I get an error beep. OK - if I click on the icon marked "Note", and a yellow box appears in the middle of the page. That is not where I want to. I have the mouse over it and hold the mouse to drag and... it does not move. Instead I am suddenly draw a line in the PDF file. Now just the small fountain pen symbol, and I can't move this note. I have to scroll down, press control-command-N... and hear a beep. Press again and it will beep. Press again and a new note will reappear in the middle. Again, I am trying to drag the note - but everything seems to be able to do is to draw a line. In the toolbar of the Markup, I see he's now on the sketch / icon "Pen and wavy line", even if I select that. I click on 'Note' again, and presto, there is another note, on top of that I was unable to move. So now, I have seven or eight notes, all piled up above the other in two different places on the PDF, with no way to move them.

    What on Earth missing am me?

    Thanks in advance!

    For what it's worth: after closing and opening the PDF file, I am now able to move the note autour boxes, so it's an improvement. The mouse is no longer randomly to the "Sketch" icon for no apparent reason. I have no idea why it did not work before.

    So my main issue now: How can I get notes or text to appear when the mouse is? Now a new note or the text always appears in the center of the window, which is not where I want it. Is this a defect, I can not change? And is it possible to add these annotations using just the mouse, with the Services menu or something similar? Right now his keyboard (or menu) to add the note or text, the mouse to move it where I want, then return to the keyboard to type. Inefficient, to say the least.

  • Submit form button save only PDF and not send.

    Our school uses a form of discipline paper and my manager asked me to created a PDF version that can be completed and e-mailed to him instead of us fill in by hand.  I've set up the Send button exactly as all the tutorials say.  When I go to test (mailto function is correct in shape), instead of a selection of email client, I get a box "send PDF data under".  At this time, he wants to save the form and the e-mail never sends.  Any ideas on what I am doing wrong?  Thank you very much.

    Thank you all for your comments.  I found my problem.  It turns out that our copy of Adobe Acrobat Pro X has not been updated.  Once our IT Department updated, it worked fine.  Thanks again for looking at my problem.

  • __Upgrading for Vista Ultimate - Dell Inspiron 1420 can't restart and not sound

    I just upgraded from Vista Home to Vista Ultmate and my Dell Inspiron reboot correctly... remember to come by saying she does not restart... gives me a lot of options (safe mode,..., normally).  The only way to get it to start is to force a complete power down (holding the button power for 10 seconds) and then try to restart about 3 or 4 times.  Very weird.

    I also no longer work on board are involved.   I went one of the Dell forums and followed exactly the lwhat they said (add drivers in a specific order and restart each time) and it still doesn't work.

    Appreciate any help.

  • VCenter hosts can be allowed and not allowed at will?

    Hi all

    I'm about to test vCenter which will have 2 Guest ESXi connection to an equallogic SAN for storage. Currently, they are all running ESXi 4 Free edition, but I have 3 host license. I need to use one to do some tests of e/s in different conditions (number of network cards, etc.). ESXi free edition appears to be limited in what he can do (for example, you cannot configure jumbo frames) compared to what can be a licensed version.  I have only 1 host printers ESXi to use for this, but at the end of the tests, it must be formatted and used for another project.

    Thus, it is possible to use one of the licenses 3 host for this test host, to allow access to some features of ESX during the tests... and at the end of the tests remove this license, reformat the host and can be reused on a production host (once you get bought in the future)?

    Yes, this shouldn't be a problem.  But in the end when go you to the free license you can not manage their in vCenter under a free license, as you know, does not come with a vCenter agent license.

  • Force 10 GbE 10/40 MXL: one port can be marked and not identified to any VLAN different at the same time?

    Dear all,

    I have to configure a 10/40 GbE switch MXL. In my scenario, each port 0/1-12 has access to 3 different networks.

    1. Management (VLAN: 10)

    2 storage (VLAN: 11)

    3. Admin (not identified)

    I can assign ports to access many VLANs. (labeled tengigabitethernet 0/1 - 12). But what happens if I have to pass the traffic which is not marked as well?

    Kind regards

    A trunk connection has a vlan native who is used for untagged traffic. Take a look at this document, he detailed step by step for a network connection.
