  OK, after reviewing the, I don't think you'll be able to write a function of decryption for him.

  The first thing he does is take the ascii value of each character in the password and converts them into a binary string.  The code it uses is far too complex and can be simplified, but which is not a problem here.

  Now, the problem of decryption is that these numbers are concatenated without padding for a fixed number of digits by value, so you don't know if it was

  '12' |' 4'||' 12' |' 9'||' 13'... and so forth as we did it, or whether he was

  '1'||' 2'||' 4'||' 12' |' 9'||' 1'||' 3'... and so on, or any other combination of values from 0 to 15

  There is essentially no information to allow you to divide the string upwards in the correct components to allow the whole process be reversed.

  So, you are out of luck... no chance of decrypting it.

• write an analytical function custom to get the current time

  Hi all
  I want to write a custom analytical function to get to the current week.
  for example if it is today, January 13, 2012 then during week 2 the analytical function must return true.
  
  I have an existing analytical function for the passage of time, written by someone else as below.
  
  Decode (connect_by_root (LASTDATE) - trunc (sysdate),-1, 1, 0)
  
  here last date it receives from the other query. This function returns me if the current date is passed or not.
  
  So can someone please tell me how to write a custom function to get the current week.
  
  
  Thank you

  I have an existing analytical function for the passage of time, written by someone else as below.
  Decode (connect_by_root (LASTDATE) - trunc (sysdate),-1, 1, 0)

  Is not an analytic function.

  I guess (because we don't know) that you need a function analytical, because you have a start date, but no end date and so an analysis as an ADVANCE or a DELAY can help you get the end_date.

  If so, then maybe this shows you in the right direction.
  I limited to 5 weeks to keep the short output.
  I chose a start date of January 3, 2012.

• How to write a generic function.

  Hello
  
  Can someone tell me the concept, I have to get hip to in order to write a generic function that will work on any object?
  
  Here is the project: I'll be show 24 graphs, (imported as Bitmaps and BitmapData jpg), and I would like to create a function where onRollover graph would be tween on twice its size, then come back to the original dimensions when the mouse is released. Pretty simple.
  
  I'm OK with everything about the import of jpg files and to implement the action of Tweener. And I think it's good to be a better way to write different functions of RollOver and RollOut for each graph, but I must have been absent that day.
  
  When I use 'this' in the function, it behaves like 'this' is planned: any change! But it's not what I'm shooting.
  
  I expect to write the function ONCE and apply it to all the graphics after that I have addChild-ed them, but I can't figure out how to set the variable (in the function) which refers to some object (Bitmap graphics) is set up to the course.
  
  I declare a public variable or something? And match to what is reversed? No need a step by step tutorial, just of me not to point in the right direction. I'll ask Shupe and Rosser. :)
  
  Oh, uh, Flash CS3, AS3... (I prefer to use the Flash environment because I'm still not enough good for simply create the .as files.)
  
  Thank you!

  Each of your JPGs load as a MovieClip/Sprite. Say mc1, mc2...
  Then set properties for all the clips as below

  MC1.buttonMode = true;
  MC1.mouseChildren = false;
  MC1.addEventListener (MouseEvent.MOUSE_OVER, onMouseOver);
  MC1.addEvenListener (MouseEvent.MOUSE_OUT, onMouseOut);

  function onMouseOver(evnt:MuseEvent)
  {
  new Tween (evnt.target, "x", Regular.easeInOut, evnt.target.x, evnt.target.x * 2, 5, true);

  new Tween (evnt.target, "y", Regular.easeInOut, evnt.target.y, evnt.target.y * 2, 5, true);
  }

  This is what helped?
  Tell me if you need something more...

• Use to write key VI with a table of cluster

  Hello

  I wanted to use an array of clusters to define certain configuration settings for an application. Unfortunately, 'Write key VI' does not support the type of cluster. Has anyone modified this function ('write key VI') in support of cluster and cluster table? Otherwise, no idea to keep it as simple as possible?

  My clusters include boolean, path, U32 and string.

  Thank you

  Olivier

  FYI, I have eventually save the cluster as a binary ("Write to binary function') file and a VI to read/write it. Is the easiest way for me as the other functions seem to have a limit on the complexity of the clusters they can handle.

  Thnaks for your suggestions,

  Olivier

• filtering of the data sent to write to the file of measure

  Hi everyone, I was wondering how to implement a "filter" that prevents the data to write in the function "write into file measuments.  Say if the incoming data is a 0 (DBL), hwo to prevent it from being written?

  Use a box structure.  Put your writing to the file of the measure within a case structure, probably in the REAL case.

• 2 parallel while loops with functional overall to share data

  Hello

  I'm having a problem with the sharing of functional with globals data between two parallel while loops:

  1. One of the loop (bottom) generates a random number periodically and write the total functional sample.
  2. Another loop (above) has a structure of event and when it expires, he would read the functional global and intrigue, a chart data point.

  The problem is sometimes the functional overall seems to be 'locked' and the output becomes zero constant. It also seems that whenever I first open the VI, it works fine. But for the second time running, he begins to have the problem.

  

  You must initialize your VI stop FGV FRONT of your lower loop begins.  Even if you use a global variable that is functional, you have a race condition.  FGV is read in the lower loop until it had a chance to be initialized with a value of false in the upper loop.  Functional global variables do not forget their data between executions of the VI.  So it is always set on stop the last time that you ran the VI.  This works your VI the first time it's because VI does not have in memory, so when it loads, it loads with the default value False in the shift register.

• Help function LabelField

  Hello

  I use many LabelField controls in the project do not wish to repeat the same code & would like help in creating a reusable function.

  Example:

  Import net.rim.blackberry.api.phone.Phone;

  LabelField lfOwner = new LabelField ("owner:" + OwnerInfo.getOwnerName (), DrawStyle.LEFT)
  {
  public void paint (Graphics g)
  {
  g.setColor (Color.DARKGREEN);
  g.setBackgroundColor (Color.WHITE);
  Super.Paint (g);
  }
  };

  LabelField lfOwnerInfo = new LabelField ("owner:" + OwnerInfo.getOwnerInformation (), DrawStyle.LEFT)
  {
  public void paint (Graphics g)
  {
  g.setColor (Color.DARKGREEN);
  g.setBackgroundColor (Color.WHITE);
  Super.Paint (g);
  }
  };

  As you can see, the two are LabelFields with graphics by placing of the same color. It makes no repeat the code point and would be better to be able to pass information to a function to set the color for label... Creating a class using a variable public to access the info above which is converted into a string before being passed to the LabelField control. Each LabelField will be in the same format:

  LabelName (sText + ":" + sText2, DrawStyle.LEFT);

  or

  MyLabelName ("owner", PhonesOwner(), DrawStyle.LEFT);

  producing a

  Owner: [name of the owner of some here]

  Following label:

  The owner Info: [info from the owner here]

  and so on

  That's what I wrote, but doesn't seem to work:

  ' Public Sub SetGreenLabel (field field, String sLabelText, String sFunctionName)
  {
  field = new LabelField (sLabelText + ":" + sFunctionName, DrawStyle.LEFT)
  {
  public void paint (Graphics g)
  {
  g.setColor (Color.DARKGREEN);
  g.setBackgroundColor (Color.WHITE);
  Super.Paint (g);
  }
  };
  };

  May extend to pass the ForeColor as parameter

  ' Public Sub SetLabelColour (String sLabelText, String sFunctionName, PlayStations color field, field)
  {
  field = new LabelField (sLabelText + ":" + sFunctionName, DrawStyle.LEFT)
  {
  public void paint (Graphics g)
  {
  g.setColor (cColour);
  g.setBackgroundColor (Color.WHITE);
  Super.Paint (g);
  }
  };
  };

  Perhaps an overload of the function as follows:

  SetLabelColour (String sText, String sText2)

  SetLabelColour (String sText2, String sText, color cForeColour)

  SetLabelColour (String sText2, String sText, cBackColour color, color cForeColour)

  My public variable

  MyClass mc = new MyClass();

  Label

  LabelField lf1;

  MC. SetLabelColour (lf1, 'Owner', PhonesOwner());

  Any ideas on how to write the correct functions?

  Thanks in advance

  Sure. Here is a more elaborate version of the idea of the subclass that has multiple constructors, commented to indicate what is happening. I have also set the colours.

  public class ColorLabelField extend LabelField {    /** Foreground color */    private int fg;
  
      /** Background color */    private int bg;
  
      /**     * Construct a ColorLabelField with empty text, default     * colors of dark green foreround and white background,     * and default style as determined by LabelField.     */    public ColorLabelField() {        this("", Color.DARKGREEN, Color.WHITE);    }
  
      /**     * Construct a ColorLabelField with indicated initial text,     * foreground and background colors, and default style.     * @param text the initial text     * @param fg the foreground color for the text     * @param bg the background color for the text     */    public ColorLabelField(String text, int fg, int bg) {        super(text);        this.fg = fg;        this.bg = bg;    }
  
      /**     * Construct a ColorLabelField with indicated initial text,     * foreground and background colors, and style.     * @param text the initial text     * @param fg the foreground color for the text     * @param bg the background color for the text     * @param style the style for the field     */    public ColorLabelField(String text, int fg, int bg, long style) {        super(text, style);        this.fg = fg;        this.bg = bg;    }
  
      /* No Javadoc comment. Just because. :) */    public void paint(Graphics g) {
          g.setColor(fg);
          g.setBackgroundColor(bg);
          super.paint(g);
      }
  }
  

  If you wish, you can add accessor functions to set the foreground and background colors after the ColorLabelField was built. As written, once you create them, the colors are immutable. (As far as the style of any field bits are immutable). If you add these accessor functions, you should consider if disabled then automatically the field when colors are changed or if it must remain until the client code to invalidate after everything he's done.

• function table

  Hi experts

  
  I want to know how to create a table function that returns the Recordset (empno, ename, sal + comm) of the emp table

  I know that this can be done with simple SQL, but I want to learn to write the table function.

  And how to call this function from another sql table.

  Please help me...

  The sample data is data.

  EMPNO, ENAME, JOB HIREDATE DEPTNO COMM SAL MGR

  Table function returns a collection of lines (a nested table or varray). You can choose from this collection, as if it were a database table by calling the function table inside of the TABLE clause in a SELECT statement. However, the use of the results of the function table based on table producing the entire collection (and remember, the collection is stored in memory) and then sending it only to the SQL statement. Table function in pipeline using PIPE ROW to route the data to the SQL statement as part of collection is produced. This SQL statement way working on this element table in function transformation pipeline while working to produce the next item in the collection. This improves performance and reduces the memory usage which can be even more important when the function produces collections of great footpring. RTFM in pipeline and functions using parallel Tableanyway.

• Help with a case function

  Hello

  I want to create a function box where column2 is based on the value of Column1.

  For example, the table below

  On the underside, I would ask something like

  Select status, description, l3_days, (case when status = 'Open' and DEV_DAYS = null THEN L3_DAYS = 'LOGIN_DATE-SYSDATE' WHAT status = 'open' and DEV_DAYS! = NULL THEN DEV_DAYS = L3_DAYS ELSE LOGIN_DATE-L3_DAYS-SYSDATE, DEV_DAYS END)

  

  Not sure so clearly. Basically, I want to L3_DAYS and DEV_DAYS to be updated automatically based on the login_date. I plan to add a DEV_START_DATE column, which would facilitate the calculation of DEV_DAYS

  In any case I want to know how to write a case function, where denotes Column1 Column2?

  Thank you

  There are two CASE statements like this

  select status
       , description
       , case when status = 'Open' and dev_days is null then LOGIN_DATE-SYSDATE
              else l3_days
         end l3_days
       , case when status = 'Open' and dev_days is not null then LOGIN_DATE-L3_DAYS-SYSDATE
              else dev_days
         end dev_days
  

  If this isn't what you are looking for you need to explain your best condition. Provide a CREATE TABLE script and INSERT a TABLE for examples of data and provide a few example expected output.

  Also please read Re: 2. How can I ask a question on the forums?

• Reusable functions?

  Is it possible for me to write some JavaScript functions to which all my rules and transformations can visit his profile?  Currently, I am cutting and pasting in each script.  I hope that there is a better way.

  Hi Eric,.

  The "functions/methods" dialog 'Custom libraries' list to create publicly exposed methods/functions, which can be selected in the dialog box "Scripts of custom transformations". Of course these function names must match the names of real functions in the code. They will be detached from your tasks. Other functions (not exposed in this example) in the code will be common code, used on many places is called/appellant/from other functions.

  I attached the below code and screenshot

  It is a very simple example of library with functions:

  

  That's how you use it in the script transformation dialog box

  

  Here is the code

  // this is publicly exposed
  function doSomeImportantThing() {
  // your logic goes here
  tables = model.getTableSet().toArray();
  for (var t = 0; t
  I guess that's what you're looking for
  		   

• PL/SQL functions as LOV to use in another display object

  Hello

  We had a custom search to extract data from a display object and the data displayed as a Table of ADF. Now, there are few requests for searches on this report. Go see criteria and Panel request if we allow saved search. But the fields used in the research are going through a lot of logic and thus the PL/SQL functions are implemented. We used to call these functions and lists separated by commas and then divided the list into individual elements and put in the component "select options".

  The value (String) returned by the pl/sql function is something like - APAC, EMEA, NORTH AMERICA, FDA

  I am creating a LOV based on SQL-query "Select getRegions() from dual;

  Now, I want the list separated by commas to divide so that I could use this LOV in an another view and try the display criteria and saved searches.

  I tried to assign as LOV just to check and the criteria drop-down view for region displays same value as single element - "APAC, EMEA, NORTH AMERICA, LAD."

  I want it to be 4 separate - elements

  APAC

  EMEA

  NORTH AMERICA

  DVL

  Is there anyway to achieve this?

  Or better is at - it another way to do this (maybe I'm wrong)

  Thank you.

  JDev: 11.1.2.4

  Instead of a programmatic VO of PL/SQL, I found sometimes easier to write PL/SQL functions that return a table - need to CREATE a TYPE for the data items to be returned and a TYPE of TABLE IMBRIQUE tabular form of the first kind.  The function returns the type of table, and can even be a PIPElined table function.  Then I create a VO with the following text:

  SELECT * from TABLE (my_function_returning_table)

  The function can even take parameters, which you fill with variable BIND your VO.
