• the associative arrays containing the record type, cannot be used first

  I am having trouble with the declaration of an associative array containing the Types of records and iteration using FIRST and NEXT functions.
  This problem of mine is only appear when I use that types of records, the FIRST and FOLLOWING operators work very well when you use the regular NUMBER.
  
  Trying to get the first element of the array, I get: ORA-06550: line 22, column 40: PLS 00382: expression is of the wrong type
  
  See the code snippet below. Anyone know if this can be done in PL/SQL?

  DECLARE
  
  
  -Set the record structure that will contain information on a post

• Array.Shift () sets the target table AND any referenced by table

  I have a class that creates an array from a xml configuration file.  I put a variable private in this class and that you use a getter in other classes to access the table.

  the routine that uses the table does the following:

  -call the getter and assign the value returned to a local variable tmpArray (private).  the Get accessor is a simple return() by using a value that is created in the constructor.

  -use a loop for itterate on content

  -use array.shift () to the element pop tmpArray

  the next time I run the routine, the content of the table is empty.  I use the getter similarly.  I've implemented the getter when I tried to manage the two tables in the same class, thinking that as long as the original array has been private (I also tried static), that wouldn't change the value.  I have since got around the problem by movine routine that fills the original value of the manufacturer, to the Get accessor.

  then, consider the following code:

  import flash.events.Event;

  btn.addEventListener ("click", btnHandler);

  var monTableau = new Array();

  var myTmpArray = new Array()

  MonTableau is ['one', 'two', 'three'];.

  myTmpArray = myArray;

  function btnHandler(evt:Event)

  {

  for (var i in myTmpArray)

  {

  trace ("myTmpArray.length:" + myTmpArray.length);

  trace ("myArray.length:" + myArray.length);

  myTmpArray.shift ();

  trace ("myTmpArray.length:" + myTmpArray.length);

  trace ("myArray.length:" + myArray.length);

  }

  }

  This returns:

  myTmpArray.length: 3

  myArray.length: 3

  myTmpArray.length: 2

  myArray.length: 2

  myTmpArray.length: 2

  myArray.length: 2

  myTmpArray.length: 1

  myArray.length: 1

  If I create a variable myVar and set it to 1 then set myOtherVar = myVar equal both the same value

  If I change the value of myOtherVar, myVar is not affected.

  but using the shift() method changes the original and the copied table.

  myTempArray IS NOT a copy of myArray but REFERENCE to is - shift() so affect them both.

• error device "sequence contains no matching element.

  Hallo,

  I just got the VirtualBench and I could use it as I connect it for the first time. I then downloaded and run the program to Window7, so that I would be able to run the program from my PC.

  Since then, I can't work increasingly with the virtualbench. It still gives the same error: device error: sequence contains no matching element.

  What it wronf what should I do?

  Note: I've read a similar question, but it seems that the error missing somehow for some unexplained reason. So, there was actually no mentioned of solution for this problem.

  Thanks in advance for any help.

  Hello Zach Hindes,

  Your idea has solved my problem.

  After the zero (button at the rear of the instrument virutalbench) I could successfully start the application. The error message disappeared and I could interactively use the instrument interactively.

  I reinstalled the software on my PC (Win7) and it runs smoothly also.

  The solution is so simple that I wonder that I wasn't thinking about him in the first place...

  Then, I suggest that developers could add the suggestion to reset the error message. I am sure, that would help a lot of people.

  with my best regards

• Determine whether an array contains elements of another array

  I have an array whose length is not know (TABLE 1)
  I have another array whose length is known (TABLE 2)
  
  I have to see if the table 1 contains elements of table 2 and then form another array that contains elements that are not present in the table Array1.
  The values that I face is int values. Also I don't know if I should use tables or any other collection.
  I tried to go an and compare other but does not know this exceptionas of arrayIndexoutOfBound gives the length of table 1.
  Please suggest how to proceed.
  
  Thank you

  I want to do another painting where I can put the elements that are in array2, but not in the table array1. How to make
  >
  There are several ways to do so. Where is the best depends on how many items it can be in each table, if the elements, or both, the tables are already in a sorted order, and if these are real berries or instances of a Collection class.

  If you want to just brute force, then we forget about loops nested and just do the simple way. Here is pseudocode, which should be enough for you to write correct code. This method is very effective for all but very little evidence of the table

  boolen existsInArray1;
  ArrayList array3 = new ArrayList;
  -for each element (index value) in array2 loop
       -if notExistsInArray1 (array2[index]) then
              array3.add(array2[index]);
       -end if
  -end loop
  
  -new method returns true if parameter exists in array1
  public boolen notExistsInArray1 (int myInt) {
      - for each element (index value) in array1 loop
             if array1[index] = myInt return true;
      -end loop
      return false;
  }
  

  For a larger number of items you could order to each of the tables in the order, then through table array1 array2 looking for the item. You would keep track of each index value of paintings. If the first element of the array array2 is smaller than the first element of the array array1 it cannot therefore in the table because the list is sorted. So you increment the index of table 1 and test again.

  This method is similar to the way in which two sorted files are merged or mapped.

  Another way is to create a GAME (does not allow duplicates) for the elements of the array array1 and then use the 'contains' to check each element of the array array2 to see if it belongs to the whole.

  CollectionUtils Apache Commons Library also has a method "disjunction".
  http://Commons.Apache.org/collections/apidocs/org/Apache/Commons/Collections/CollectionUtils.html

  disjunction
  public static java.util.Collection disjunction(java.util.Collection a,
                                                 java.util.Collection b)Returns a Collection containing the exclusive disjunction (symmetric difference) of the given Collections.
  The cardinality of each element e in the returned Collection will be equal to max(cardinality(e,a),cardinality(e,b)) - min(cardinality(e,a),cardinality(e,b)).

• You must pass values of 'return' of item selection list while trying to assign the value via a URL. Make sure the audit and PUB. ScanEvent are the correct return values
  
• Make sure that the child value is good for the selected parent value. that is, the table PUB. ScanEvent must be a child value for DB audit. If you pass an incorrect combination of parent-child of the values that have been created as cascading, only the parent value is defined.

• If test item in the array to set the digital limit

  I would like to test if a global chain of the station is a member of an array of resort chains. If this is the case, I would use a special digital limit and so do not use the normal limit.

• Deletion of items in array containing "999.0.

  I have a table of 10 items of type DBL. I would like to delete the item if it is a value of 999.

  For example, the original array is [1.0 1.5 1.6 999 999-6.9 999.0 0.0 4.7-0.1] size 10, the final table should be

  [1,0-1, 5-1, 6 6.9 0.0 4.7-0.1] of size 7.

  How to do this?

  Hi Peter,.

  have you ever noticed your RubeGoldberg-construct?

  An improvement (a little):

  

  -Keep in mind: using the "remove table" is not very effective when it comes to large paintings and a lot of elements to remove.

  N ' forget not: you get bad very quickly trying to compare numbers float for equality. There is a lot of discussion on this topic.

  -Keep in mind: Search1DArray has an index entry. This could help to speed up the illustrious excerpt.

• What is the setting for element Apex in the middle of the region

  Hello good evening everyone,

  I tried with the parameters

  and also with the settings of the grid Yes

  Version 4.2.4 apex

  Blue Builder theme

  

  I want that this Summit (view point) to be at the centre of the region

  Any idea

  Hi ReemaPuri,

  Your theme is generator of blue which was available to the element in the form of

  Tag (and taking into consideration the last thread, where you are showing the error message in a single display element), why don't change you your view-only point in another region with model say "No. Template/Borderless region" of the region. (Make sure that your area is #REGION_STATIC_ID # substitution string). Give your area a static id i.e. error_region and then you can write the following css to set your error display only point to the Center:

  #error_region table.formlayout {
    width: 100%;
    margin: 0 auto;
  }
  

  I hope this helps!

  Kind regards

• Apex 5, call a modal page, set page elements, in values referenced title page elements are not the same (correct) than the item itself

  Hello

  Apex 5.

  IR (departments) on page 2 I want to open a modal page 3 (classic report) with the detail data (from emp) for a Masters depno via a link on depno column.
  In Page 3, I created two elements P3_DEPNO and P3_DNAME. These elements are defined in modal page 3 of page 2.
  When I do these two visible elements on page 3 I can see, the values are set correct according to the value in column (depno) link on page 2.
  However, I would like to place these element values in the page title of page 3
  Title: PGE for DepNo: & P3_DEPNO., DepName: & P3_DNAME.

  It happens that the values mentioned in the title of the page are not the same (good) as in the items himself.
  Initially, they are NULL. Only when I refresh page 2 the values change but remain the same (last called depno) as long as I'm doing a new refresh of page 2.

  I wonder how I can run to display the values of the correct point in the title of the page corresponding to the values of the correct page element (that I have hidden).

  Y at - it something more to do, or it could be a small bug?

  I've created a little demo app on

  Page title is rendered before the page elements, that is why is not highlighted in your title.

  I don't think directly, we can use the page as a page element value.

  Creates a copy of yours and made the change it new App id - 45390

  There, I created a static area without a model before your report area and put your article into that.

  then displayed title PGE for DepNo: & P3_DEPNO, DepName: & P3_DNAME. for the area of your report.

• With the help of APEX_UTIL. SET_SESSION_STATE to set an element value in Session State?

  Goal: Refresh a region but not the entire page, where the region has a query based on the value of a page element, that the user has selected. I (think) I () would be the updating of the region works well but the page element that uses the query is not in State of Session!
  
  The current issue: I have a procedure (APEX_UTIL. SET_SESSION_STATE) to assign a value to the user enters the Session State, but how do I get this value in the first place?
  
  What I have in the region:
  : P23_SELECT_RUN_DT (date picker)
  Lines extracted according to the date picker. Initially, the query retrieves all rows because: P23_SELECT_RUN_DT (date picker) is null.
  
  I'm trying to follow {message identifier: = 9781139},
  I added a DA (event: change) with the following PL/SQL:

  BEGIN
      APEX_UTIL.SET_SESSION_STATE('P23_SELECT_RUN_DT','???');
  END;

  But how do I specify the value to use is the date picker? I can't use: P23_SELECT_RUN_DT; It has the value null.
  
  I added this: point P23_SELECT_RUN_DT for an example, I'm already working:
  WS: APEX_EXAMPLES_01
  USER: demo
  PW: demo
  Application: 991203 - BPR_991203 Page 23 (tab: Master 3)
  Click the edit Pencil after 'ProgramName 1' to fill the three regions. The date picker is the third region.
  
  What is the approach to use? Can someone suggest an easier way to achieve this?
  
  Thanks in advance,
  Howard

  Re my goal:

  The current Question:... to assign a value that the user enters into the State of Session...?

  I thought that maybe this works. I added P23_SELECT_RUN_DT 'Page to present '. I removed the former DAs. Then I added a refresh of the region for the date picker, thinking that the: P23_SELECT_RUN_DT value would be submitted whenever the changed date picker. No joy. The newly selected value is not in Session State.

  You're going to hate this :D (although I admit it's obscure uber - I was quickly running out of ideas when I noticed it...)

  The problem is the static region ID BPR_RUN details. It is not valid HTML ID attributes cannot contain white spaces. I do not know exactly why the presence of the verboten discombobulates APEX or jQuery so space overall, and I'm not venturing in the debugger to determine. I'll just point to it as another reason to respect some HTML and use the markup compliant to standards.

• Set the element hidden in Javascript

  Hello
  
  I'll have a hidden page P4_SELECT element in my page. I'm putting this article on the page with a javascript function value.
  

   function getTheCurrentRow(triggerItem){

  }
  </script>

  Even if I get the value in the "Undefined P4_SELECT" javascript error alert
  
  When I checked the 'view Source' of the page is to have this line in
  

  <input type="hidden" name="p_t04" value="" id="P4_SELECT"  />

  I tried
  

   $x(P4_SELECT).value=triggerItem.slice(6);

  But getting the same result only. We cannot set values of the element hidden by Javascript.

  Hello

  If you're on Apex 3.x or higher, try

   $s("P4_SELECT", triggerItem.slice(6));

• CS4: Get all the UIDS of pages containing a page element

  Hello

  How can I get all the UIDS of page, which contains a page with a specified UID element?

  For example: I have two UIDS of pages if a page item is placed on two pages.

  Thank you

  Hans

  Jongware probably confuses the problem with page elements spread master.

  I think you talk page possibly items on several pages in a spread.

  ILayoutUtils::GetOwnerPageUID is a good start.

  If you want more details, browse the pages of your broadcast and match covering them for the bounding box of the element on the page.

• Rendering problem when setting ChoiceBox elements with a service

  I am preparing some examples to show the various features of FX when I came across this strange issue. I use a javafx.concurrent.Service to populate the items of a ChoiceBox. When I click the ChoiceBox to display a list of choices, I get only a blank rectangle with a triangle drawn on top. It's only when I click on the triangle the ChoiceBox gets correctly redrawn. From what I could see in the debugger is that the elements are there at the time when I click on the ChoiceBox.
  

  final ChoiceBox<String> choiceBox = new ChoiceBox<>();
  ExampleService service = new ExampleService();
  service.setOnSucceeded(new EventHandler<WorkerStateEvent>() {
       @Override
       public void handle(WorkerStateEvent aEvent) {
            ObservableList<String> tempValue = (ObservableList<String>) aEvent.getSource().getValue();
            choiceBox.setItems(tempValue);
       }
  });
  service.start();

  Published by: Thilo 13 November 2012 10:57 to repair broken links

  Looks like a bug to me. It is not related to the use of a service (or multithreading): the code below suffers from the same issue.

  import javafx.collections.ObservableList;

  public class ChoiceBoxTest extends Application {
  
    @Override

      primaryStage.setTitle("Example 3");
  
      final ChoiceBox choiceBox = new ChoiceBox<>();
      final Button populateButton = new Button("Populate");
      populateButton.setOnAction(new EventHandler() {
  
        @Override
        public void handle(ActionEvent event) {
          ObservableList tempValue = FXCollections.observableArrayList();
          for (int i = 0; i < 10; i++) {
            tempValue.add("Item " + i);
          }
          choiceBox.setItems(tempValue);
          // This will work:
          // choiceBox.getItems().setAll(tempValue);
        }
  
      });
  
      VBox root = new VBox();
      root.getChildren().addAll(populateButton, choiceBox);
      primaryStage.setScene(new Scene(root, 300, 250));
      primaryStage.show();
    }
  
    public static void main(String[] args) {
      launch(args);
    }
  
  }
  

  To work around this problem, replace

  choiceBox.setItems(tempValue);
  

  with

  choiceBox.getItems().setAll(tempValue);
