How to get a DVR to persist after the creation of VI closes?

Hi all

I try a few new architectures and I am struck by a problem. I hope you can help.

I want to do it is create a DVR in a toplevel VI and then go this DVR to a second VI which I can run by using the invoke node. In particular, I want to make an asymmetrical appeal so I put 'wait until what"false.

A valid reference is passed to the second VI. However when the toplevel VI stops the reference (now also in the second VI) is destroyed. I tried both options with the flag "Auto have Ref" (and I think that it is not related in any case).

Can anyone help?

Many thanks in advance,

Dave

Enjoy what you have observed;

DVR is alive as long as the creator is alive.

Creating the DVR in a Subvi, which is also part of the hierarchy of the VI th spawn you.

  • Problem with XNET start VI after the creation of sessions

    I have a timed loop sending CAN messages via XNET screws. It works great, but I always lose the very first message. It matters little, I send the first message immediately after you create the XNET session or after a few milliseconds.

    The attached screenshot shows the initialization of my four sessions XNET. Although I am starting before the session with an XNET start VI, there is without success to get the first message.

    It seems that the sessions/CAN (selectable cards and HS CAN) interfaces are initialized only after the first call to write XNET. XNET write seems to imply XNET start (see documentation), but the appellant XNET start manually after the creation of sessions does not help.

    What I'm missing to get the interfaces online and ready before you send anything?

    I was able to solve this problem because they did not actually XNET screw sorry for this post.

  • vCAC 6.0 cannot connect after the creation of the tenant

    After the creation of a new tenant for use with vCAC 6.0, I disconnect from the default connection ([email protected]) and continue to go to the new URL and connection. When I do, my connection attempts fail. I followed the documentation and even used this blog entry as a reference to make sure I wasn't missing a step (vCloud Automation Center - vCAC 6.0 - addition of tenants - DailyHypervisor). After trying to connect with a users AD I created, I get the same error "username/password Incorrect name."

    Attached are the screenshots of the new tenant that I created.

    Hello

    There are two of them:

    (1) use the workflow of "notification" of the library-> just Mail and build a group (comma seperated or e-mail, Distributor)

    (2) you can program it or build a timer on hold until the date is reached

    Hope this helps

  • How to get an original RAW image after cropping and openness RAW file?

    Hello

    I have a Canon EOS 350 d camera and now PSE 9.  I have taken a few RAW images & imported in PSE 9 OK.  I know that the original RAW image is preserved after the change.  However, after cropping a picture BRUTE of the editor and then "Open" and "save under" a PSD or JPEG, I then close the image in the editor and the cropped image appears in the Organizer.  This is as it should be, I think.  If I then want to start from scratch on the original RAW image, it seems to me that I have to manually remove the modified version and the .xmp file in Windows Explorer, and then double-click the RAW file in Windows Explorer, which then open correctly in the editor of PES 9 of origin.  Is this possible to PSE 9?

    When you open the original camera raw image, go to the context menu

    and choose default Camera Raw, which resets everything except the crop, straighten,

    and rotatate parameters.

    To get rid of the culture and/or straighten the settings, click on and hold on to the crop tool and choose the option clear crop.

    To reset the settings of Image rotation, you have the back turn manually using the image rotation buttons.

  • How to get back a few characteristics of the rocket?

    I was very happy owner of a Sansa Fuze (without "+") for many years. It has proved to be very robust, even on a sailboat off the coast. I use it mostly to listen to audio books. Then, when the rocket + is out, and he has addressed my main desire: be able to come back after the beginning of an audio file (and had a USB plug instead of the industrial property), I don't think twice and just bought. But I was very disappointed; It is almost useless for my use and end up using the "rocket" much more than the rocket. My main problems are:

    1. There seems to be no way to navigate through the folders. All audio files are presented in an alphabetical list of time - hundreds of them! Switching between audio books takes several minutes and intense concentration, since scrolling is often beyond.

    2. with the touchpad, rewinding also takes a lot of time and concentration. It is a feature that I often need, because when I'm listening to foreign language files, or when I'm interrupted, I need to go back a few seconds.

    3. it cannot be used in your Pocket: the controls have no haptic feedback and are so sensitive that they get easily exploited to sit in a pocket. (Unlocking also relies on a visual feedback and takes time; so it cannot be used in any situation where you want to immediately respond to interruptions)

    Is it possible to get at least some of these features is back with an update of the firmware? I read somewhere that a firmware update improved navigation, but I already have 02.38_06A, which is later that I could find by Google for "sansa fuze firmware update site: sandisk.com.

    Most of your problems can be solved by installing Rockbox. Unlock, it's only a little faster with is (like everything else), you can program to automatically rewind each time that put you paused and has better file navigation (you can't even update the database if you want!). Rockbox also will give better performance of the battery. But beware: is not go back through the title!. If you don't like, you can also start the original firmware by pressing the Volume down when you turn it on.

    If you are interested, see HERE for instructions on how to install Rockbox (uninstall instructions can also be found), HERE for a PDF of the manual, HERE version for the HTML version.

    Other than Rockbox, the only thing I can suggest is a different player. Whatever it is, good luck!

  • How to get to InDesign to concentrate on the text selection

    Hi all

    I'm trying to select text in the application window. Currently, I'm trying to browse a few found texts and then after the change is made visually review the changes.

    What I can't understand is how to get the application to focus on selection when its generated through the ARE? To specify if you do a search with the graphical interface (ctrl + f) and change find it that: field in the user interface, and then click next application will select the text found and Center the window around this selection.

    Line 04 point I would like to require the selection to appear in the InDesign window.

    arrFoundTexts = app.findGrep();
arrFoundTexts[0].changeGrep();
arrFoundTexts[0].select(); //tested and does not bring Text into GUI focus
app.select(arrFoundTexts[0]);//tested and does not bring Text into GUI focus

    Thank you in advance for your time and care to help me find the answer.

    Text objects have a method called showText() which is done exactly as described above - don't know how I missed it.

  • How to prevent a landslide which is after the results of the projection page quiz?

    HI guys, I am reaching what follows in Captivate 6:

    (1) users answer questions. They have 2 attempts to 70% or more.

    (2) to the quiz results page, if the score is less than 70%, users get a button to resume the quiz. After the second attempt, if the percentage is 70% or higher, they can click a button to display a certificate or click on a button to see a transcript. If the percentage is less than 70%, they click a button to get a transcript, but NOT a certificate.

    How can I achieve this because I can not add buttons to the quiz results page.

    It is true that in previous versions that you cannot add buttons to a slide of score, but possible in Captivate 6: double forms like buttons and they have all the features of regular buttons, but they can be added to the masters, slldes of the question slides and the slide of score. I'm trying to find time to blog more about it, but for me, it's one of the most important novelties of the COP6.
