How to open multiple vis at a time

I'm having one main vi. In that my own menu is running.By clicking the menu i want to open and run different vis at a time.But i can to able run only one at a time.Anybody help me please.Its like opening many child windows from MDIwindow in VB

Too many VIs missing to make a good example of the ones you sent, however I have made an example for you; download the attached llb file and open the main.vi in it...run it and you will see two VIs pop up, they are the "children" which produce data. Move the sliders in the child windows and you will see the values reflected on the front panel of main...
Use the type of global shown in the example, it's called a functional global...Rebuild it to hold whatever data you want to share among the VIs. Using functional globals are much better than using ordinary globals (as described in the text I referred you to in the first answer).
A few comments about the example; here the fundtional global just holds the last value, it does not buffer the valu
es. If you wanted to ensure that what was displayed on the panel of main.vi you would e.g. make the global a a circular buffer.
Controlling where on the screen the children pops up would be preferable; in that case you would read the position of main prior to opening the children...and set the position of the children so that they fit nicely at one of the sides of the main window...
Here the children monitor the front panel of main.vi and close if that panel is no longer open...a more general approach would be e.g. to use notification and perhaps also rendevouz to synchronize the exit...

    HOW TO OPEN MULTIPLE TABLES IN SQL DEVELOPER SIMULTANEOUSLY

    Use the 'pin' on your table editor
    http://www.thatjeffsmith.com/archive/2011/11/sql-developer-quick-tip-pin-query-result-sets-and-plans/
    Then open your 2nd table. If you want to see both at the same time, right-click on the table editor tab and select 'New Editor Tab Group'
    Not a silly question, but no need to shout :)

  • Opening multiple visa sessions

    I'm having problems with opening multiple VISA sessions for communicating with 4 HP-34401A multimeters in LabVIEW 6.1. If you have a little bit of time, please take a look at what I have here to see if I'm doing something wrong.

    I have made a look at your VI. I don't have the driver for the instrument I couldn't go into the subVIs and its documentation and I could not change it for you.
    1. You initialise only 2 of the 4 meters. Initialize all meters.
    2. In sequence 0 you close the session to the meter. In the next loop iteration it will not measure as you intended. Delete the "VISA Close" function.
    3. The stop button would cause the while loop to exit. But your handling is a little bit complicated. Do following:
    Delete the "not" and case where the stop terminal is connected. Wire the stop terminal directly to the termination terminal of the while loop. With the context menu set it to "stop if True". Wire the VISA sessions to the right border of the while loop and connect t
    hem to the "VISA Close" function.

  • How to Enter multiple inputs at a time in Form or Table

    Hi,
    I have one doubt in Webdynpro with java. How to enter multiple inputs at a time?
    For Exam My requirement is we will take employee details node under node empid, name, sal  etc some attributes is here
    Client asking like this enter multiple inputs at a time that data will saved in ECC System.
    1.     By using form how can enter enter multiple inputs at a time I donu2019t this so I will take table(here I will select input fileds). If any possible in form also tell me how I can enter multiple inputs at a time.
    In table suppose 6 rows available So He will enter
                             empid, name, sal  ,firstname, last Name
                             empid, name, sal  ,firstname, last Name
                             empid, name, sal  ,firstname, last Name 
    Like 6 time Click Submit. That data will save in ECC.
    So I was taken table. But in that Table only first row will be editable. I want all 6 will editable that time he will put data in rows then click on submit.
    How to editable these remaining rows? if u have any documents pls send me.
    Regards
    Vijay Kalluri

    Dear Vijay,
    To enter multiple inputs in a table and to make the other rows editable you have to provide that node with initial values.
    by initial values I mean you have to make that much space in your table node.
    For example the name of Node is  yourNode & you have empid, name, sal ,firstname, last Name
    attributes in that node, and you have to make 6 rows editable.
    Then, simply write this code in you wdDoinit() method of your view controller.
    IPrivateYourView.IYourNodeElement e ;
    for(int i = 0 ; i < 6 ; i++ )
    e = wdContext.nodeYourNode().createYourNodeElement();
    e.setAttributeValue("empid" , "") ;
    e.setAttributeValue("name" , "") ;
    e.setAttributeValue("sal" ,  "") ;
    e.setAttributeValue("firstname" , "") ;
    e.setAttributeValue("lastname" , "") ;
      wdContext.nodeOverTimeEnty().addElement(e) ;
    Change YourView with your view name & YourNode with your node name.
    If you have any problem in doing this you can revert back.
    Hope it helps!!
    Warm Regards

    Doug's got it right. It sounds like you are trying to open a later version file in an earlier version. This will always be handled as opening the PDF portion of the file. Try Googling AI_openMultiPagePDF for a script to open these or Resave from the newer version to the older.

  • Can I open multiple bookmarks at a time like on the desktop version of Firefox has Open in All Tabs?

  • How to open multiple collapsible panels?

    http://labs.adobe.com/technologies/spry/samples/collapsiblepanel/collapsible_panel_sample. htm
    This "Open Panel with Link" sample opens only one panel, but
    I'd like to open multiple collapsible panels at the same time with
    one button/link click.
    I'm trying to use a class name "Collapsible Panel" instead of
    the id name "cp1, cp2,cp3,cp4, ....", but I'm stuck on how to
    open/close by class name.
    If anyone knows how to do it, I'm appreciated to hear it.
    Thanks,

    I'm not sure if this is what you're going for, but here is an
    example of using a text link to open multiple collapsible panels:

    onclick="CollapsiblePanel1.open();CollapsiblePanel8.open();">Click
    to open</a>
    <a href="javascript:;"
    onclick="CollapsiblePanel1.close();CollapsiblePanel8.close();">Click

  • How biztalk handle multiple request at a time ?

    can TCP/IP adapter or biztalk handles multiple request at a time ?
    If yes,then how it process multiple request ? 
    Can TCP/IP send ports sends multiple request ?
    Prakash

    Yes.
    It processes multiple requests using THREADS. Each Connect starts off a thread that handles the receipt of the message, submission to BizTalk, wait for the response (matching two-way subscription) and then respond back to the client.
    TCP/IP Send ports handle multiple requests by creating fresh sockets (RPC High-end ports). As an example, in your browser you open multiple tabs and access different sites, each tab results in your browser opening a fresh socket connection for the request.

  • How to open multiple jpgs in Adobe Camera Raw PSE 9 Mac

    I am using Adobe Elements 9 on a Mac.  I can open a single jpeg file in ACR with the file open command.  There is no "Open As" in my version, probably because this is the Mac version.  But, there is an additional dialog which allows me to open the jpeg file and select "Camera Raw" as the type.  This opens the jpg in the raw editor.
    But, when I select multiple files to open, the type dialog vanishes.  Rather than opening the files in ACR, they are stacked in the main editor.  I don't have this problem opening multiple dng files - just multiple jpg files.  Multiple jpg files will not open in ACR.
    I then went to the organizer, which replaced Bridge?  In Bridge, I read there is a command to open multiple files in ACR or use the cmd-R.  However, I am not seeing an open in ACR command in the organizer, just open in editor.  Opening multiple jpg files in the organizer stacks them into the editor, not ACR.  And, typing cmd-R brings up Red Eye reduction, not Raw Editing.
    Is there a trick to this which I am missing?

    Thanks Terry! I’ve been using this for a few years and settled on the somewhat more flexible approach… As you mentioned, Bridge offers an explicit command to open a JPEG or TIFF in Camera Raw, which I do, but then with a press of Shift I can open that JPEG as a smart object and revisit CR controls for further adjustment at any time later in the process.

  • How to Open Multiple Files into One Image with a Format Plug-in?

    Basic overview question:
    I'm interested in creating a format plug-in that will open multiple image files and combine them, then provide one image to Photoshop for further work.
    1.  Can an .8bi plug-in receive notification of multiple files to be opened?  (Not unlike Camera Raw).  Or does one absolutely need to use an .8ba Import plug-in to do this?  I would prefer .8bi.
    2.  Assuming yes, could the latter parts of the plug-in interface be used to open just one combined image?
    Thanks!
    -Noel

    1) An import plugin (8bi) doesn't get file information - it has to provide it's own open dialog.  Only a file format plugin gets a file, but only one at a time.  (ACR has some special magic)
    You might want to take a look at the PhotoMerge and MergeToHDR setups with a script driving a plugin.

  • How to open multiple files on one layer

    hi there,
    I have a fairly simple problem and I browsed through all the different FAQs to find it but nothing came up. In any case, my question is how do you select multiple files (in this case PNGs) and open them as individual layers on one file instead of opening them as separate files?
    easy huh? I'm a noob ok.
    thanks

    Russell Brown has a CS4 version of his services.
    As Wolf points out, if you have CS4 then you already have access to a script that will also do what you want. I happened to notice though, that the built-in script and the Russell Brown script work slightly differently. The RB script will crop all images based on the first one loaded. The built-in script will apparently use the dimensions of the largest image.
    It was a nit but I thought the title of the thread would be more accurate as "Help opening multiple images as layers in a single file" or something like that.
