Multiple copies of a single VI??

I need to open multiple independant copies of a single VI with front panel. I realise this can be done by re-saving multiple copies of the VI but as i do not know until run-time how many copies are required this is not a good solution. The VI is an instrument user interface and thus i require each instance of the VI to display its front panel and act independantly. Cheers for your help

I don't know what the discussion on templates involve, but it isn't really the proper solution to your problem (although that discussion may in fact be about the proper solution: instanciation, but be missnamed.)
What you need to do is drop in a "Call by Reference" node. This will call an "instance" of your VI (load a copy of your VI into memory.) To call your VI, you need two things: a prototype, and the path. The prototype is just a copy of the connector pane. You can just open your VI, view the connector pane, and drag-and-drop it onto the Call by Reference node. You can now wire your inputs and outputs. If you have no inputs or outputs, you can just use the VI server, which you have to use anyway for the next steps. You need to create a referenc
e to the VI using the Open Reference. Wire a constant to the Path input, and use the path to your VI.
Now that you have that done, or if you are going to use only the VI server (if you have no inputs or outputs), you need to drop some invoke/property nodes. If you are only using VI server to call your interface (again, if you have no inputs or outputs), you need to Invoke the VI. Check out the VI Server examples for help on this. Then, you will need to use Property nodes to make the front panel visible. Be sure to also name your instance each time, so that the system isn't confused.
If you still have problems, let us know where you get stuck.
Good luck

  • Why am I getting multiple copies of a single email?

    I'm using Yosemite 10.10 on my mid-2012 iMac.
    I've noticed that I'll often get multiple "copies" of the same email. E.g., this morning I received an email that was forwarded to me as a contact through one of my weblogs. In the Mail Inbox for the specific email account the same email appeared three times.
    I've noticed this same behavior in other email Inboxes (different accounts) in Mail.
    Any idea what's going on?

    This may have to do with the server, what kind of email are you using, and is it a group email?
    Can you please provide steps you are taking with a little more detail as well? It may be a known issue, but I do not know.
    I look forward to your reply!

  • How to print multiple copies of a single report(label) based on a variable

    I have a crystal report v.9 linked to an excel file with multiple rows of information.  Each row contains the label information and one column has the quanity of each label to print.  What feature in crystal do I use and what is the command I will need?   The information changes on a daily basis so I need a formula. Thanks in advance.
    Kurt

    There have been a few posts that have answered this in the past.  (I know because I answered them! :-> )  You might want to search for them.
    But basically, you want to do something like this in an SQL Command data source (MS SQL):
    declare @loop int;
    set @loop = 1;
      -- copy table structure (or otherwise create a temp table):
    select * into #temp from table where numLabels < 0 and numLabels > 0;
    while @loop < 20 -- or whatever a maximum number might reasonably be
    begin
      insert into #temp select * from table where numLabels >= @loop
      set @loop - @loop + 1
    end
    select * from #temp order by name, address  -- something to keep copies of labels together

  • How do you print multiple copies of a single photo on one page in iPhoto 9.5?

    Help. Duplicating the photo as many times as I need it and then selecting them to print works, but in the last version of iPhoto you could explicitly choose to do just this. How do you do it now??

    That feature has been removed from the latest version of iPhoto. Send a feature request to Apple via http://www.apple.com/feedback/iphoto.html.

  • Duplex printing of multiple copies of single page

    I really like that the settings for printing are retained so you can leave it set to duplex rather than having to select it each time. Although I do get caught with not resetting the number of copies on occasion. I do a lot of printing and like to conserve paper.
    The problem is when duplex is set and I print multiple copies of a single page, it prints on both sides of the paper. When printing two copies I get one page printed on two sides instead of two pages printed on one side.
    I know the easy answer is reset the duplex setting. But it should print correctly regardless. Has anyone had this problem and found how to deal with it other than resetting duplex?

    If these settings are in the printer driver (which they most likely are) then you'd have to contact the driver manufacturer. Perhaps there are multiple "double-sided" settings. For instance, if there is "duplex" as one option and "two-sided" as another option in the driver, then perhaps one indicates all copies will be printed double-sided even on the same page (as you're experiencing), whereas the other would print multiple two-sided copies. This, however, is very driver-dependent behavior. I'd recommend checking to see if there's an update available for your printer driver that might either clear the problem or provide a clearer option setting for the print jobs.

  • HOW DO I PRINT MULTIPLE COPIES OF ONE PHOTO ON A SINGLE PAGE?

    Since Apple has not made this feature available, I am not able to print multiple copies of a single photo on one page. HELP suggested I download Portraits and Prints which I could use for free. However, I have downloaded this and note that DEMO watermark will appear on all photos unless I purchase the program. Is there a way to print without the DEMO watermark using this program or is there another free program that will allow me to print multiple copies of a single photo on a single page? Please help as I have spent 2 hours on the phone with Apple and it has gotten me no closer to a solution - something I could easily have done on the older versions of I Photo. Thanks!

    Sadly, I have no pull down menu when I click on Customize or settings? I am using IPhoto 08 vers. 7.0.1. I was told by Apple HELP that this feature is not yet available, even though the instructions say to do exactly what you have said. But there is no pull down menu and no option to print multiple photos. It says print a single photo and it is clicked and I cannot unclick it. Any help would be appreciated. Do you actually have a pull down menu with Print Multiple Copies of One Photo as an option? What version of IPhoto provides this? Apple seems to think it is not available and it certainly isn't available on my system. Any help will be appreciated. Thanks.

  • How to print multiple copies of same image (with specific fixed dimensions) on single page

    I am using Photoshop Elements 10 on Win 7 PC.  I am trying to print multiple copies of one image on a single 8.5x11 sheet of paper? The images are artwork for buttons (to be used in button-making machine) so the dimensions must be exact on the duplicated images.  When I select Picture Package, the images are resized to fit the dimensions in the picture package. When I select Contact Sheet, the images are resized to fit the number of columns I selected.  Neither is acceptable.  How can I repeat the same image on a single piece of paper without having the system re-size the image?  I know that I can manually create a new PSE file and manually insert the images into this file.  This is what I have been doing as a work-around.   But I would hope there is a better/faster way.
    Thank-you!

    A variation of hatstead's method where the pictures are precisely aligned:
    1. Add the picture to the blank file as hatstead described. Use the Move tool to position the picture in the upper left corner.
    2. Duplicate the layer. Use the arrow keys (NOT the mouse) to move the new layer to the right.
    3. Repeat step 2 until the row is filled:
    4. Merge Down the 3 layers into one. Alternatively, link the 3 layers and do a Merge Linked as in this example. The end result is the pictures in the row are on one layer:
    5. Duplicate the layer and use the arrow keys to move this down to the 2nd row.
    6. Repeat step 5 to create additional rows.
    7. Finally, to center the whole thing on the sheet, link all the row layers and position with the arrow keys.
    Note that you can also custom-make your own Picture Package. Instructions for this should be somewhere in Help.

  • Receiving multiple copies of text messages

    i have an iPhone 6 plus and have been receiving multiple copies of the same text message (up to 4x) from various contacts across various carriers. This has been an issue throughout having an iPhone 5s and 6 plus, and only occurs with regular messages, not iMessage. It also does not occur for automated text messages sent to me (e.g. Redbox). While I have unlimited messages it is frustrating because they are sent to me multiple times, and not necessarily in the same order each time. It is also inconsistent. I might get a single copy of one text and four of another. I have reset the phone, changed phones, and every other thing possible. This seems to be an issue not on my end. Assistance would be much appreciate.  Thanks.

  • Printing multiple copies of 3 page BOL in Duplex mode-

    Hi Gurus!
    I have created a smartform to print the BOL on front side and terms and conditions on back side. I used the duplex mode to print and it works perfectly fine. When I have a BOL with 3 pages of information , it prints the items on the front side and terms and conditions on the second side and it does everything absolutely correctly.
    At our organization we always print 5 copies of any BOL and that is when the problem arises. When we do a printing of the BOL form with number of copies set to 5 , it prints very akwardly with the settings. First it prints page 1 front and same thing on the back, then  again the first page on the first and its back and then front on the third side , then similarly 5 sides of terms and conditions and then followed by 5 sides of page 2 items and followed by 5 sides of terms and conditions, which is very akward. Actually it should print first set with page 1 and TC on back of it , then Page 2 and TC on its back and page 3 and TC on its side like it does when I make a single copy.
    Is there any settings that I am missing thats making the above happen when I print multiple copies of the BOL?
    Please suggest.

    Hi!
    Thanks for the reply. I changed the settings of the printer to 'Pass Copies as Separate Output Request(in SAP System)' and re-tried printing 5 copies of the BOL and it again seems to print the first page 5 sides then Terms and conditions on 5 sides, then again 5 sides of page 2 and followed by 5 sides of T&C.
    My settings on the smartforms is front page "D' and the back and the Last page is blank setting. This runs well when I just have to print one copy of my BOL , it prints the front page and then T&C on its back side , then again the second page and T&C on its back . This only messes when its more than one copy of the set of BOL.
    Please suggest as to what to do next to make it print in proper sets.
    Thanks and Regards

  • Generate and Print Preview Multiple Forms in a Single PDF

    There have been other questions similar to this but none directly address my problem.  We have the need to generate multple forms in a .pdf using Adobe interactive forms.  We can generate the multiple forms, but the user has to click on each form to view.  They want to have the forms in a single document that they can scroll through before printing.  We can do this in SmartForms but need to do it in Adobe.  Does anyone know how to generate multiple forms, either multiple copies of the same form or various forms, from an ABAP program into a single pdf that can be print previewed, in scrollable form, by the user?

    I can describe it one more time, I think:))
    You have multiple options, but only one "reasonable" within SAP.
    You can call an external application (through command line etc.) to concatenate forms for you.
    You can use iText as mentioned in the thread, and write yourself a "tool" which will concatenate the forms for you.
    Both these "options" would not be acceptable for my clients, I name them to help you get the whole picture.
    Then there is the third option: use a form for a single instance (template/ form A) and create a new form (form B), where you will use the A template:
    - you need to: create a new interface where everything from the old interface is a row of the table (example: you have a form to print out the personal card of the employee, so in a new form you will need to use a table, where a row is an employee)
    - you need to create a new form layout based on the new interface:
    in this new layout you will paste the whole layout of the old form (A/ single instance) and wrap it into a subform. The added subform will work as a table (you will bind that to the table from interface) and everything from the old template within this new subform will work as a "row" (something what you can repeat for each data item).
    Does that sound reasonable?
    Cheers Otto

  • Multiple copies of JPEG on ePub export

    I'm making copies of a JPEG image and using this image in multiple places in my inDesign document. In the links panel, I see the disclosure triangle that shows all the pages that I'm using that link. So, all good so far.
    When I export the document to ePub, I would have expected there to be a single version of the JPEG file in the resulting ePub file. However, I have multiple copies of the JPEG file, all the same size, but with different names.
    So, if my original JPEG file is 1234.jpg, I'll have the following derivatives of that file in the "images" folder of the ePub:
    1234.jpg
    12341.jpg
    12342.jpg
    12343.jpg
    Then in the CSS and XHTML pages, the different uses of 1234.jpg will each reference their own version of the file, so:
    Page 1 will reference 1234.jpg
    Page 2 will reference 12341.jpg
    Page 8 will reference 12343.jpg
    etc...
    This seems very wasteful to me, as my ePub is now much larger because it has all of the duplicated JPEG files. Is there any way to avoid this, or is this expected behaviour?
    Thanks
    William

    I have ID CC 2014, 10.1.0.71
    I am exporting to Fixed Layout ePub.
    According to a previous post, this issue was addressed with the 10.1.0.70 release but that's not my experience, so wondering if there is any other solution than going through and editing the CSS generated code?

    Tom,
    looks like you are specifying http protocol in
    sky.framework.ejb.SkySessionBean.getInitialContext method.
    Change it to t3 or, if the JNDI lookup is in the same JVM, don't specify
    PROVIDER_URL. If you have to use http tunneling due to any reason , you have to
    enable HTTP Tunneling in server to which initial context is created. It is
    disabled by default in 60. You can do so via console. Please refer to
    documentation , let me know if you need additional help.

    This advice applies to WL5.1. I have been trying to configure a
    multiinstance Weblogic with no success. I want multiple copies
    of the sample petStore available for test by multiple users.
    I think in 6.0
    You would need to open an admin server
    Open the configuration file for say PetStore.
    Clone the petStore- call it petStore2. .
    Create a copy of the startup script and modify it to start PetStore2.
    After doing this only one config.xml is created for both servers.
    I am able to start the first server and view the petStore application,
    On the second server I get an error when I do
    http://host:secondServerPort/index.html
    How does one create multiple instances in WL6.0 using the console
    or using a XML editor ?

    NT isn't a multiuser environment. I will assume that
    you mean some
    Win32 box sitting in a room where people can copy their
    classes/EJBs and
    test their stuff. If this is the case, the setup is easy.
    Create a directory and startup script for every developer.
    Have a
    global properties file in the same directory as the scripts
    so that
    common settings are, well, common. Tell each user to
    modify the various
    parts of the properties files in their directories to
    deploy EJBs and
    register servlets, etc etc.
    In each startup script, you will have to specify the server
    directory
    and the binding port for each person. Pick a port (something
    easy to
    remember and high, like 30000, 30001, etc etc) for each
    person. Why?
    Well, when they connect to the app server, they'll know
    they're hitting
    only their server. Also, TCP/IP won't let more than one
    JVM bind to the
    same port, so if you want simultaneous instances (> 4
    you better have
    one kick ass Win32 box) you have to do this.
    Hope this solves your problem.
