Unable to understand the syntax index

• Can someone help me how to understand the syntax of a calculation in a form Acrobat?

  For the first time I have created a PDF form for the child summer camp brochure. After countless hours I was able to figure out how to make some simple calculations (number of sessions of camp price subtotal = x). But I can't understand how to create a script that will take partial total revenue and generate a number which corresponds to 10% of the subtotal. All I want to do is have a separate field (reduction), which can reference the subtotal, and if it's over $ 170.00, calculates and displays a number which corresponds to 10% of this amount. From there, I can understand how to subtract 10% of the subtotal, but I can't understand the syntax for the calculation of the 10%. Also I don't know if that should be entered in the Notation of Simple box field or calculation Script custom area to calculate in the text field properties box. Any help would be greatly appreciated!

  You must use JavaScript. It would be something like:

  Personalized to discount field calculation script

  (function () {}

  Get the subtotal value, as a number

  var = subtotal + getField("Subtotal").value;

  Set the value of this field

  If it is greater than 170, calculate 10%, otherwise it is zero

  Event.Value = subtotal > 170? 1 * subtotal: 0;

  })();

  This last line is equivalent to:

  If {(subtotal > 170)

  Event.Value =.1 * subtotal;

  } else {}

  Event.Value = 0;

  }

  It's just more compact.

  Replace "Subtotal" in the line of getField above with the actual name of the subtotal field. Also, set all the fields calculated read-only. And make sure the field calculation order is correct.

• Unable to understand the code output

  Hi all

  I was reading one of the codes and unable to understand its outcome, I'm really grateful if someone guide me to understand. Thanks in advance.

  Code example

  create or replace package Mp_pkg

  IS

  P_nn TYPE TABLE IS NUMBER

  INDEX BY VARCHAR2 (10);

  END;

  ----------------

  DECLARE

  l_numbers Mp_pkg.p_nn;

  Start

  FOR indx IN 1... 50

  loop

  (indx) l_numbers: = indx;

  END loop;

  dbms_output.put_line (l_numbers. (Last);

  END;

  ----------

  Result

  9

  -----------

  According to my understanding, result should be 50 because the last value of l_number is 50...

  Please guide...

  
  

  Hello

  As John said, the VARCHAR2 '9 ' (or any string '9') is longer than the string of 50', for the same reason that the string 'Z' is longer than the string "THE".

  What do we mean when we say this string x is greater than string y?  We mean that

  1. The 1 x chraracter comes after the 1st character of y (in sort order), or, if these characters are equal
  2. x has a 2nd character, but is not, or, if both are more than 1 character
  3. The substring SUBSTR (x, 2) > SUBSTR (y, 2)

  What (if any) strings mean is not serious, so

  • '9' is greater than '50',
  • 'zero' is greater than 'a '.
  • 'small' is greater than 'big '.
  • 'MIN' is greater than 'MAX '.
  • 'yesterday' is greater than 'tomorrow', and
  • "1 January 1900' is superior to" December 31, 2015 ".

  According to rule 1 Correction: rule 3 is the reason why 'MIN' is greater than 'MAX '; the others are all due to rule 1

• Unable to understand the output...

  Hi gurus

  I was reading a little code and unable to understand a single line, can someone guide me to understand this line.

  Code example

  Set serveroutput on

  DECLARE

  n number;

  BEGIN

  n: = 2 * 33.

  dbms_output.put_line (n);

  end;

  Result

  8589934592

  
  Now, I would like to know how the calculation performed for n: = 2 * 33 in the background so it become 8589934592 result. Thanks in advance.

  One of these curiosities PL/SQL in SQL vs. In PL/SQL * is same as it is built based on POWER. 2 * 33 is identical to POWER (2.33). It is documented in the Precedence of the operators:

• Unable to understand the result of the loop

  
  Hi all

  I got the tracking code:

  Code

  Set serveroutput ON

  DECLARE
  TYPE IS VARRAY months_array (12) STRING (3 CHAR);
  MONTHS months_array: = months_array ('Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec');
  BEGIN
  < < list_month > >
  FOR month number IN REVERSE 6.12
  LOOP
  dbms_output.put_line (' number month = ' | number month |) "Items =' | MONTH (MONTHNO));
  CONTINUE list_month
  WHEN number month < 9;
  END LOOP;
  END;

  Code output

  number months = 12 = Dec

  number month = 11 = Nov

  number months = 10 items = Oct

  number month = 9 elements = Sep

  number month = 8 = August

  number month = 7 cells = Jul

  number months = 6 items = Jun

  My question is if you notice the code condition which is CONTINUE list_month number months WHEN < 9 means loop must be output if number month < 9 and according to code loop starting with number months = 12 so system should display the 1st line of output that is number months = 12 elements = Dec , then exit because the loop exit condition is true that is list_month MORE WHEN number month < 9. Please, help me to understand the output.

  Hi Muzz,

  try something like this

  BEGIN
    FOR monthno IN REVERSE 6..12
    LOOP
      exit when monthno < 9;
      dbms_output.put_line('monthno= '||monthno||' Elements='||MONTH(monthno));
    END LOOP;
  END;

  Hi gurus

• explanation of the syntax of reminder

  Forgive my beginner questions.

  I am trying to understand the syntax of the callback functions that are auto-insérée in my source of CVI.  I'm not entirely understand what's the point of "CVICALLBACK" in front of my name of callback function.

  int CVICALLBACK ControlCallback (int panel, int control, int event, void *callbackData, int eventData1, int eventData2)
  

  I dive into cvidef.h, I see that it is defined as CVICDECL, which in turn is defined as __cdecl, which is apparently a "calling convention".  So CVICALLBACK is just a secondary typedef for the callback function?

  You were right from CVICALLBACK to the convention corresponding appeal. The calling convention is a very technical beast to explain, unless you are particularly interested in him (for example because you want to / have to build DLLs to be used ion other compilers or symmetrically, you can use the DLL created in other languages) you can simply ignore it and happily live and work with CVI

  However, information about the calling convention can be easily found on the internet: here and here two wikipedia pages on the subject, so that here , you will find a page of knowledge base specifically oriented CVI

• Spreadsheet Excel add after the syntax

  I have a large application that creates a report following a test.  The report is about 250 pages, each page represented as a group in the data portal.  When we deliver him customer report also wants an excel file with pairs of X - Y data for each of the graphs in the report.  I know how to make the selection of the data and copy/paste it to Excel.  Where I encountered problems, that's when I add worksheets in Excel, I can't figure out how to run the new worksheet to add at the end.

  According to the news on Excel VBA, there are parameters before and after that should allow you to do.  I can't quite understand the syntax to include these parameters.  The line of code in question is red.

  If you have nothing but the. Add the statement that the code works but the worksheets appear in reverse order.  I tried a number of different ways, and the script just dies without even showing an error.  I know one around which we work to scroll the list of the groups back, but that's not fair to sit well with me.  I prefer to do things in a logical manner, being from the first to the last.

  If there are questions please let me know.

  Thanks in advance.

  Hello Wayne!

  What you need to know, is that you can leave empty parameters. The solution to your problem is:

  Set ExcelSht = Excel.ActiveWorkbook.WorkSheets.Add (, Excel.ActiveWorkbook.WorkSheets (Excel.ActiveWorkbook.WorkSheets.Count))

• How to understand the format of hyperic shell command line?

  I logged on the hyperic shell and I just wanted to check on the orders and their
  output.  Im having trouble understanding the syntax I do a list alert and get:
  
  alert list
  org.hyperic.util.shell.ShellCommandExecException: error getting alerts
  In undeclared throwable was: java.lang.ClassNotFoundException: org.hibernate
  .collection. PersistentBag (no security manager: RMI class loader disabled)
  
  When I use the "list alertdef" command it comes back with: ""
  list of alertdef <-group | -plate-forme | -Server | -service > < resource > [-activated |-disabled]
  
  Replace - platform with linux - say? or a particular computer Devils name
  what they are referring to with resource? is the agent HQ a resource?
  
  What is necessary and what is not. . Cant seen to get anything to work.
  An example of this command is all I need.

  You will see many orders with a syntax similar to the alertdef list.  You
  do not replace the '-' keywords with anything, it has the 
  that you would replace it.  The can be the ID of the
  resource (if you know it) or the name (use quotes if there is)
  (spaces).  For example, I can do:

  alertdef list - server 10001

  or

  list of alertdef - HQ Agent server 'hq.hyperic.com '.

  In addition, as shown in my example, the central administration Agent is indeed a resource.
  It is a server.

• Warning about bad connections contains no option "I understand the risks", I can't move on

  I install Thunderbird on Windows 8.1. I am trying to add 3 accounts. When adding the second account that Thunderbird has warned by transmitting unsecured password. I clicked on "I understand the risks". No problem. When I tried to add my third account, I received the warning again, but this time there was no other choice, "I understand the risks". I can't click on 'Done', if I change the parameter that TB can not find servers. I'm stuck and unable to add my last story.

  I installed on my laptop that runs Windows 7 TB and had no problems. I use the same settings as in my version of TB on my laptop. The version of TB is 24.4 on both machines. Of course, the version of TB was younger, when I installed on the laptop.

  Thank you, in advance, for any advice.

  If I wanted to get the certificate warning when connecting to my email provider's e-mail server, I would like to seriously check the offered certificate. There should be no exceptions to this need in the first place.

  Certificates are there for a purpose, and is not simply to add an exception when it does not work.

• "I understand the risks" missing option - page is read from cache

  trying to access the Web site, I am facing a security warning because the certificate is self-signed.
  This is an internal site, which is currently the subject of tests - so it's ok to add an exception.
  the question is, the option to select "I understand the risks" is totally absent, the only available action is "get me out of here"

  Since it is an internal site under our control, I did a few tests more:
  It seems that firefox redirects the initial http request to https
  This does not happen on other browsers (chrome and IE), also tested in a clean install of firefox running without the extensions.

  even after completely cleaning the cache and temporary files, question remains.
  This site (over http) does not load on firefox, always redirected to https

  even after deleting the server mod_ssl apache and by eliminating completely any mention of the ssl on that server, connection with firefox always redirects http to https (now results in the error "Unable to connect to Server" - but still not to load the basic site http version)
