How do you pass a variable from one page to another thru a button

I have a page that has a button that goes to another page and allows the user to create a new record related to the data on the previous page.
The first page is a master, while the second page is a detail. I need the primary key from the first page to update a column in the detail page.
How do I get the primary key in the second page and how do in put the data in the correct column?

Hi Nielsen,
The master detail form should handle everything for you already...Select all rows in each table but only display the records besides the primary keys. Try creating a new master-detail form with this idea, don't bother trying to change some other page.

  • How do you pass a variable from one form to another

    Sorry, I am new at this.
    I have an ID on one form and I want to pass it to another form and then populate a text field on the second form. How is this accomplished.

    There are various ways to accomplish this depending on your applications' needs.

  • How do you pass vi references from one event to another

    I have a vi which gets vi references (thereby loading the vi's into memory) for all the vi's in a given directory when a user clicks a button on the front panel. To do this I use an event structure. My question is whether it is possible to have another event (user button on the front panel) which unloads the vi's from memory. I have tried passing the vi references that are initially generated to the close reference function but whenever I do I get a 'vi reference invalid' error. Does this have to do with trying to pass the vi references between one event and another? If I use a local variable simply pass a reference to another indicator and then probe it, the originally-generated refnum and the local vari
    able refnum match up. However once I try to wire that same indicator to the close reference function I get the 'vi reference invalid' error. Is there a different/better way to unload the vi's from memory based on a user button click? Any suggestions would be welcome.

    Several problems with your code:
    1... Bad idea to use lights as buttons. Yes it can be done, but it's not "natural".
    2... If you've gotta do that, set their mechanical action to "LATCH WHEN RELEASED"
    3... Because of #2, you are getting TWO copies of every array when you click the LOAD VIs light (er... button).
    4... No need for the conversion from path to string and back - use BUILD PATH to append each file name to he folder path.
    5... Set the BROWSE OPTIONS on your PATH control to EXISTING DIRECTORY to allow browsing of directories, not files.
    6... Your code doesn't care whether the file is a .VI file, or a .ZIP file, or a .TXT file, or what. Use the PATTERN input on the LIST function to discriminate.
    7... Your code is only storing the latest refer
    ence, not the array of references.
    8... An ERROR DIALOG on the OPEN REFERENCE function will tell you that you're getting an error. Why? You are asking to prepare a non-reentrant VI for reentrant execution (why use options = 8?)
    9... Because of #8, the latest VI reference is invalid.

  • How do I pass a parameter from one page to another page?

    Hi,
    There are two JSF pages(a.jspx and b.jspx), when click a link(e.g...b.jspx?parameter=123) on a.jspx, it will forward to b.jspx, my question is that how can i get the parameter=123 in b.jspx?
    i use adf 10g.
    thank you very much!
    Edited by: Yitao Li on Jul 13, 2009 2:20 AM

    Hello,
    I would recommend to avoid using visible parameters in your querystring.
    In adf 10g on your command link/button you can use thesetActionListener to set something in the request scope or even better, a backing bean.
                  <af:commandLink text="text"
                                  action="pageB">
                    <af:setActionListener from="<yourvalue>" to="#{requestScope.parameter}"/>
                  </af:commandLink>You can then access this value on the next page without making the paramater visible to others.
    This can be done with the code Simon provided.

  • How to pass a variable from one class to another class?

    Hi,
    Is it possible to pass a variable from one class to another? For e.g., I need the value of int a for calculation purpose in method doB() but I get an error <identifier> expected. What does the error mean? I know, it's a very, very simple question but once I learn this, I promise to remember it forever. Thank you.
    class A {
      int a;
      int doA() {
          a = a + 1;
          return a;
    class B {
      int b;
      A r = new A();
      r.a;  // error: <identifier> expected. What does that mean ?
      int doB() {
         int c = b/a;  // error: operator / cannot be applied to a
    }Thank you!

    I am wondering why does (r.a) give an error outside the method? What's the reason it only works when used inside the (b/r.a) maths function? This is illegal syntax:
    class B {
      int b;
      A r = new A();
      r.a;  //syntax error
    }Why? Class definition restricts what you can define within a class to a few things:
    class X {
        Y y = new Y(); //defining a field -- okay
        public X() { //defining a constructor -- okay
        void f() { //defining a method -- okay
    }... and a few other things, but you can't just write "r.a" there. It also makes no sense -- that expression by itself just accesses a field and does nothing with it -- why bother?
    This is also illegal syntax:
    int doB() {
          A r = new A();
          r.a;  // error: not a statement
    }Again, all "r.a" does on its own is access a field and do nothing with it -- a "noop". Since it has no effect, writing this indicates confusion on the part of the coder, so it classified as a syntax error. There is no reason to write that.

  • Pass a variable from one frame to another

    I have 2 JFrame, one just has a button which is select file, and it will get the path of the selected file, and i have another JFrame which will get that path and open up another JFrame and load up data using the filepath. How would i pass the path from one JFrame to another?
    thx

    Hi there,
    As far as I could understand your question: The second frame is created when the button is pressed? If that is the case you obviously handle the event in some kind of a listener which gets the path and then creates the second frame.
    public class MyFrame extends JFrame {
    public void setPath(String path) {
       this.path = path;
    }Now, if you separate "view" from "controller" (google MVC) you can pass it to the constructor of the "controller" class or after creating the frame pass it to a method like the one above. It is all up to your program's design.

  • How do you transfer Apple IDs from one ipad to another iPad?  I got the new ipad and gave my ipad 2 to my wife who had the first version and now I can't get my Apple ID off so she can use her Apple ID.

    how do you transfer Apple IDs from one ipad to another iPad?  I got the new ipad and gave my ipad 2 to my wife who had the first version and now I can't get my Apple ID off so she can use her Apple ID.

    You don't transfer Apple ID's from one device to another one. You sign out in the settings, )the App Store and iTunes if necessary) and then sign in with the other ID.
    Settings>iTunes & App Stores>Apple ID>Sign out. Them sign in with the other ID. You can sign out of the app store and iTunes as well by going to the featured Atab in the App Store and the music tab in iTunes, swipe to the bottom and access the Apple ID in there.
    You should have erased the iOad before you gave it to her in Settings>General>Reset>Erase all content and settings. That way she could set up the iPad as new with her own Apple ID.
    Be aware of the fact that if you use each others ID's in order to download past purchased content to your own iPads, you will lock yourself out of your own ID as you will have associated your iPad with the other person's Apple ID.
    In other words, if you sign into your wife's ID on your iPad so that you can download an app or an album so that you don't have to pay for it again, you will lock yourself out of your Apple ID for 90 days.

  • How can you move the objects from one server to another?

    how can you move the objects from one server to another?

    Hi,
    Collecting objects for Transporting
    1. rsa1->transport connection
    2. left panel choose 'object type', middle panel choose 'infocube' and 'select objects'
    3. then choose your infocube and 'transfer'
    4. will go to right panel, choose collection mode 'manual' and grouping only 'necessary objects'
    5. after objects collection finished, create request
    6. If they are $TMP, then change the package.
    7. When you click the Save on the change package, it will prompt for transport. Here you can provide an existing open transport request number, or if you like here itself you can create a new one.
    8. You can check the request in SE09 to confirm.
    Releasing Transport Request  
    Lets say you are transporting from BWD to BWQ
    Step 1: In BWD go to TCode SE10
    Step 2: Find the request and release it (Truck Icon or option can be found by right click on request #)
    Note: First release the child request and then the parent request
    Steps below are to import transport (generally done by basis )
    Step 1: In BWQ go to Tcode STMS
    Step 2: Click on Import queue button
    Step 3: Double Click on the line which says BWQ (or the system into which transport has to be imported)
    Step 4: Click on refresh button
    Step 5: High light the trasnport request and import it (using the truck icon)

  • How do i move an app from one page to another

    how do i move an app from one page to another? When I upgraded to the latest software on my 4s, the camera went to the last page rather than remaining on the home page

    What Rudegar says is true, but it's a lot easier to rearrange icons in iTunes:
    Connect your phone and open iTunes. 
    Click on the Apps tab. 
    You will see your home screen in the main window, with the other screens in a scrollable column on the right. Scroll down and click on the last page to put it in main window. 
    Now scroll the column so the home page is visible on the right.
    Click on the Camera and drag it onto the home page at the right. 
    Be careful not to accidentally insert it into another app, thereby creating a group.

  • How to pass a variable from one scene to another

    I'm making a call from one scene to another via a button, but I have two buttons calling the same scene, each for a different purpose, and I need to pass certain variables tied to each button to that called scene. How can I do this?

    import flash.events.MouseEvent;

  • How can I pass an exception from one thread to another thread

    If I create a new class, that will extends the class Thread, the methode run() can not be use with the statement Throws Exeption .
    The question now: Is there any possibility to pass an exception from one thread to another thread?
    Thx.

    It really depends on what you want to do with your exception. Is there some sort of global handler that will process the exceptions in some meaningful way? Unless you have that, there's not much point in throwing an exception in a thread, unless you simply want the stack trace generated.
    Presuming that you have a global handler that can catch exceptions, nest your Exception subclass inside a RuntimeException:
    public class NestedRuntimeException extends RuntimeException
        private final m_nestedException;
        public NestedRuntimeException(final Exception originalException)
            super("An exception occurred with message: " + originalException.getMessage());
            m_nestedException;
        public Exception getNestedException()
            return m_nestedException;
    }Your global handler can catch the NestedRuntimeException or be supplied it to process by the thread group.

  • Is it possible to pass a variable from one animation to another?

    I have multiple animations on the same page. I need to pass a variable from one to the other.
    Animation One has this:
    sym.setVariable("myVarOne", 1);
    Animation Two has this:
    var myVarOneInTwo=Edge.getComposition("EDGE-12345678").getVariable("myVarOne");
    Seems like it should work, but kinda hard to tell. I put in:
    console.log("myVarOneInTwo = " + myVarOneInTwo);
    But I get: Javascript error in event handler! Event Type = timeline
    So it seems that it doesn't like getting a variable from another animation.
    Is there a way to pull a variable from one animation into another?

    Sorry also had to fix this:
    var myVarOneInTwo=Edge.getComposition("EDGE-12345678").getVariable("myVar One");
    To this:
    var myVarOneInTwo=Edge.getComposition("EDGE-12345678").getStage().getVariable("myVar One");

    I have three pages of apps, not all of which are full.  How do I move apps from one page to another to have full pages?

    Hook your iPad up to your computer and iTunes and move them from within iTunes.
    Or
    Hold down on one of  your apps until they all start to wiggle. Then hold down on the ones you want to move and drag them on the screen. Drag them to the middle left to move them left,(such as from page 2 to page one) middle right ot move them right,(from page 2 to page 3) rearrange as you want.
    When you're done, tap the home key and everything should stop wiggling.
