How to make the current value default programmatically

How to make the current value default programmatically

Open a VI reference to the desired VI and use invoke mode with method: "Make current values default".
The VI cannot be running, so you need to set it from a different VI. (It also means, it cannot set itself.)

  • How to make the current values in the frontpanel as standard values (in an exe-file)?

    There are some posts to this topic, but I couldn't find a satisfying solution to this.
    Simply example for what I am looking for a solution: The fronpanel includes one numeric input element. I start the VI, change the value of the numeric input element to an other value and than stop the VI. The next time I start the VI I want the numeric element to have the value that it had when the VI was stoped. Preferably, I want the value of the numeric element be setted up as "standard-value"  when I push a button (see the example attached).

    I put together a very basic example, which should give you the idea. Find it attached (this subVI only works with doubles).
    Of course the toolkits which Sam_Sharp mentioned are much more "pro" solutions with much more options...

  • How to save the current Indesign defaults file?

    Hi, I've tried following the Indesign Classroom in a book but I find it left a lot to be desired for anyone new to this e.g ME!!!!. So can someone please tell me how I can save the current InDesign defaults file on a windows and if you can please do so like you would, for lack of a better word or term, an idiot because I'm fitting that description pretty well right now. Any help will be greatly appreciated and you will forever in my mind be a god, thank you =DDDDD.

    Hi, im not too sure (I thought it was a stock standard thing, sorry) so I'll fust give you the instructions my book has.
    To save the curren InDesign Defaults file, Follow these steps:
    1, Quit Adobe InDesigns CS5.
    2, Locate The Indesigns Defaults file.
         . In Windows, the InDesign Defaults file is located in the Documents and Settings/Users/Username/Library/ Application Data/ Adobe/ InDesign/ Version 7.0/en_US folder.
    3, Drag the Indesign Defaults file to another folder on you hard drive.
    When you launch Adobe Indesign CS5 after moving the InDesigns Defaults file to another folder, a new InDesign Defaults file is automatically created and all prefrences and defaults are reset to their original factory setting.
    Okay that's all of it and as far I can get is to the app data, for some reason my notebook doesnt have it and I've been trying to find other ways of getting to it but im having no luck. I would really like to avoid the Ctrl+ Alt+Shift thing because I'll apparently lose any saved settings that I might want to keep.
    Hopefully that all makes sense, thank you for responding and your time =3.

  • How to get the current values of LINESIZE and WRAP in SQLplus ?

    How do I get the current values for the SQLplus environment variables
    When I type

    Is there a command to show ALL existing current paramter values at once ?

    SQL> show linesize
    linesize 134

  • How to display the current value selected in DDLB of another screen

    hi Experts
    I need some info regarding the dropdownlist in BSP.
    I have two screens . One screen contains the table view which contains a set of records.Each record has two columns.
    Second screen contains 2 drop down list.
    When i select one record and then press the submit button in the first screen .Then i want that the selected value of the selected record will display in the DDLB of the second screen. And then i can again select the value from the drop down list.
    For example:
    1st screen:
    record 1.
    col 1     col 2
    record 2
    col 1     col 2
    2nd screen
    So when i select the record1, then the current value of col1 and col2 should visible on the ddlbs of second screen first time. Then i choose other value from the ddlbs.....
    My Question is how to do the following
    "when i select the record1, then the current value of col1 and col2 should visible on the ddlbs of second screen".
    please provide some suggestions...

    You can use form with post method
    <htmlb:form method = "post"
                      action = "page2.htm"
                      target = "coding" >
    <htmlb:dropdownListBox id             = "labelAlignment"
                                               selection      = "<%= me->labelAlignment %>"
                                               onClientSelect = "document.forms[0].submit();" >
                          <htmlb:listBoxItem key   = "LEFT"
                                             value = "LEFT" />
                          <htmlb:listBoxItem key   = "RIGHT"
                                             value = "RIGHT" />
    So once you select col1 and col2 in your case its value is in page attribute say hold, this attributes needs to be defined in page2.htm also with auto checked. You can get the val selected in page1.htm

  • How to make the same value be placed in many  variables.

    Hi all!
    I need help to make the values broght from ekpo-peinh: 1 2 3 4 5 etc...  get placed into many fields of internal table, for example:
    data: begin of it_size occurs 0.
            t90 like ekpo-peinh,
            t10 like ekpo-peinh,
            t11 like ekpo-peinh,
          end of it_size.
    And I need to make that all the values from ekpo-peinh be placed in order in it_size-t90 = 1, it_size-t10 = 2, it_size-t11 = 3, it_size-t12 = 4 and so on.
    So please if anyone can help me 'cause I don't know how to do that, I'll really appreciate it.
    Thanks for your time.

    Hi Guillermo.
    I'm not sure i understand completely, but here's part of a solution:
    data: l_comp type i,
    field-symbols: <f> type any.
    describe field it_size type l_type components l_comp.
    do l_comp times.
      assign component l_comp of structure it_size to <f>.
      if sy-subrc ne 0.
      move (value from EKPO) to <f>.
    This will populate, in order, your IT_SIZE structure with a value (EKPO-PEINH).  I'm not sure how this value is managed, but this should give you an idea.

  • How to read the current value of hyperlink java bean in multiple record,

    I have used a java bean for a multi-record block item. On When-new form-instance I m using fbean package as follows

    You can see that I am using the number 1 which is hardcoded,for which I will replace with a incremental loop and remove it. Now when I m using the When-Custom-Item-Event, I want to read the URL for the current instance.
    I m using

    to get the second record value , where in I want to avoid the hardcoded 2 or 1

  • Making Current Values Default While VI is Running

    Is there a way to 'make the current values default' while a VI is running?

    You know, i try to read these posts really quick because i do this at work
    (my boss doesn't mind because i learn things too). Anyway, my dyslexic mind
    interpreted the subject line as initialize to default values. Sorry. Craig,
    i think that's twice you corrected me. Thanks.
    But now i have a question. Why would you want to set the current values
    to default? So after stopping then re-starting the program it starts with
    the last know values? (i know, thats really 2 questions). The way i do
    this is to use the simple configuration read and write vi's to some ini file.
    On program close, write the values. To make sure this is done, take the
    stop button away from your users and use a front panel quit button that will
    execute the write code before calling labview exit. Obvisously, on program
    start, read from this file to return your controls to the last know states.
    Hope this helps, sorry for the confusion.

  • Make current values default

    Hello ng,
    Can anyone tell me how to programatically make
    the current values of all controls on a panel the

    Furthermore, can I set all controls back to their
    default state programatically?

    Are we talking about LabVIEW 5 here? If so check out the VI Server
    In the Functions palatte under Application Control you can open a VI
    reference to
    a VI with Open VI Reference and then using the Invoke Node you have both
    "Make Current Values Default" as well as "Reinitialize All to Default
    These functions match exactly the same commands in the Operate menu.

  • Reversing the Make Current Values Default command

    I was working with a labview program this evening and had been using the 'Reinitialize all to default' command under the operate menu to clear all of the waveforms on my screen.  However, I accidentally chose the 'Make current values default' command and cannot erase what shows up in the waveforms.  I am sure there is a simple fix to my problem but I couldn't figure it out.  I tried rewiring parts of my block diagram do exclude the waveform graphs with the hope that the waveforms would go away but realized that the graphs weren't wired so nothing was going to change.  Any help would be appreciated.
    Thank You,
    Go to Solution.

    There are a few simpler ways than closing and reopening the VI.
    If you realized the mistake right (or soon) after you did it, a ctrl+z will undo the operation and you have your old defaults back.
    If you are past that stage, a simple "menu...file...revert" will revert the VI to the last saved version. No need to exit and reload.
    If you accidentally saved it with the new defaults, "right-click the operations...clear graph", make default, save VI again.
    Good luck!
