• How to create unique variables in loops? (AS2)

  Hello

  I wonder if it is possible to create variables in a loop for which uses an incremental number in the name of the variable.

  This is the code I tried (like a long shot) but does not work:

  var i: Number;
  for (i = 1; i < 10; i ++) {}
  var ['number' + String (i)]: number = i;
  }

  trace (number5);

  What I'm trying to create here is a series of variables called "Number 1", "Number2" and 'Number3', etc. Is there another way to do it? I need them to be public (I think that's the word?), so they can be used elsewhere in the script.

  I would appreciate any advice.

  Try this:

  for(var i : Number = 1; i < 10; i++)
  {
      this["number" + i.toString()] = i;
  }
  trace(number1); // will output 1
  

  

• How to use a static const variable while loop collection ArrayCollection?

  Hello

  I have an arraycollection collection which I get to main system, that has two columns named, 'Id' and 'Desc '.

  I created a static const variable:

  public static FIELD_DESC_NAME:String const = 'Desc ';

  I have been using this variable const everywhere in my code, for example:

  super.dataProvider = model.acVariants;
  super.labelField = FIELD_DESC_NAME;  instead of using super.labelField = "Desc";

  But unfortunately, there is one place where I'm not able to use it. And it's all in the loop as shown below:

  for (var i: uint = 0; i < model.acVariants.length; i ++) {}

  If (value.label is model.acVariants [i]. DESC) {/ / I want to use the FIELD_DESC_NAME variable, instead of using 'Desc' model.acVariants [i]. / / DESC}
  super.selectedItem = model.acVariants [i];
  break;
  }

  }

  Can you please let me know how can achieve us?

  Appreciate your help...

  <! - Deepak - >

  Can you put a debug statement and draw the value returned by model.acVariants [i] [FIELD_DESC_NAME] and value.label

  Hope that there must be a difference.

  If this does not solve then please let me know

• How to combine the string and variable in loop

  I need to get the following lines in a loop for, but miss me the possibility in actionscript3 to use this ['string' + i + 'word2'
  
  wing_mc.prop1_mc.rotation = - wing_mc.rotation;
  wing_mc.prop2_mc.rotation = - wing_mc.rotation;
  wing_mc.prop3_mc.rotation = - wing_mc.rotation;
  wing_mc.prop4_mc.rotation = - wing_mc.rotation;
  wing_mc.prop5_mc.rotation = - wing_mc.rotation;
  wing_mc.prop6_mc.rotation = - wing_mc.rotation;
  wing_mc.prop7_mc.rotation = - wing_mc.rotation;
  wing_mc.prop8_mc.rotation = - wing_mc.rotation;
  wing_mc.prop9_mc.rotation = - wing_mc.rotation;
  
  I tried things like
  
  for (i = 1; i < 10; i ++) {}
  This ["wing_mc.prop" + i + "_mc"] .rotation = - wing_mc.rotation;
  }
  
  or
  
  for (i = 1; i < 10; i ++) {}
  "wing_mc.prop"+ i +"_mc".rotation = - wing_mc.rotation;
  }
  
  It seems very simple
  I must be overlooking something
  
  Thanks in advance

  "Although it works there is a little thing, I do not understand:
  This.wing_mc ["prop" + i + "_mc"] .rotation
  I think a point to separate the this.wing_mc ["prop" + i + "_mc"] AND .rotation '.

  Well, that's how. In fact, the syntax is similar to the table. There are no points when you read the value of a member of the group. In a way that object is an array of methods and parameters - we simply refer to them not whole but by name.

  I know it's all confused sometimes. :-)

• Try to make a variable with loop for

  Try to retrieve an instance of movieClip in my library and set it on stage and clickable menu do, (list drop-down/dropup)).

  This ["m2" + i] .addEventListener (MouseEvent.Click, clicking);
  }
  }

  function clicking(event:MouseEvent):void {}
  trace ("I am clicking on the button" & event.target.name);
  }

  Remember that you have to work with the positioning and the TextFields overlap takkis, that the click is possible only in a minor fraction of the takkis.

  You know, in your code curr_rec is not slider.
  You cannot use curr_rec % rowcount
  If you want to get the number of lines of your loop, then use an additional variable

  Try this please

  declare
   countLoop NUMBER :=0;
  begin
    for curr_rec in( select * from dual)
    loop
      countloop := countloop + 1;
  
    end loop;
    dbms_output.put_line(countloop);
  end;
  

  or

  DECLARE
          CURSOR csr_org IS
                SELECT empno, ename FROM   emp;
                num_total_rows NUMBER;
        BEGIN
                FOR idx IN csr_org LOOP
                    dbms_output.put_line(idx.empno||' '||idx.ename);
                    num_total_rows := csr_org%ROWCOUNT;
                END LOOP;
                IF num_total_rows > 0 THEN
                  dbms_output.new_line;
                  dbms_output.put_line('Total Organizations = '||to_char(num_total_rows));
                END IF;
     END;

• Notofication, local variable which is the efficient education Department

  Hi, I want to pass a variable to loop A loop b, I wonder which is more effective, the Notification or local variabe?

  Well, both are equally effective. If it's just a one-way road loop A loop B, you can just use a local variable, but you can run any questions if you need all the data. If the loop of the local written writer then there is no way of knowing whether the other loop has already read, so it will crush him. Also, the receive loop has no way of knowing if the data has been updated. If the receive loop needs that value the latest then you can go out with a local. But you must read continuous him when a notifier allows you to just 'wake up' the receiver loop when the value is written.

• Need help cleaning a recursive loop, please.

  Hello again,

  I'm on another quest to write a function completely fool proof to a very specific task in Illustrator. The task is to create a new work plan in the target document (determined by a guest of small script user interface) which is a certain distance from the existing chart with the highest index Board (so I'm still putting the new plan of work at the end). After I created the work plan, I want to activate the source document and duplicate all the layers (a few layers are empty but will be used later) and work in the doc of the target and place them on the newly created artboard.

  With the help and advice of Silly-V , I wrote a recursive loop to handle the situation of nested layer. This brings me to the first part of my question. Please take a look at recursion and let me know if there is anything I can do to clean it up and simplify as much as possible. (I know it looks really messy. I've learned how do on the fly and I changed a lot of variables and loops after the fact, just trying to make it work). I hope also that somehow slightly more efficient to work this will improve stability as well. As it is, I can only run this script 3 or 4 times (if I'm lucky), before I get persistent errors of MRAP on trivial things such as: layers.getByName("Information").visible = false; At this point, the only recourse is to stop illustrator and reopen files. So I'm usually good for a few runs more...

  Part 2 of my question is the following. Is there a way to reproduce the work from one document to the other, and place it on the new artboard rather than the artboard [0]? Currently, art is duplication of artboard [0] the doc from the source to the artboard [0] the doc of the target and then I manually manipulate the implementation by defining: this.left this.left = + (artboards.length * 2100). First, it is just steps adding too much to the script and slow things down I'm sure. The second problem that is after 4 work plans, I need down another line (to keep from spilling onto the pasteboard). That adds another layer of complexity and a lot more if statements to determine how far from move it and in what direction.

  Here's the script in its entirety. Please do not hesitate to rip it and ask me WTH I thought. According to carloscanto, script.elegant is definitely fake.

• Need help: loop of pl/sql with UTL_FILE reading and analysis of file text 2

  Hello, I am working on a new project using the UTL_FILE utility in oracle 11 g. and I was wondering if someone could help me with a pl/sql code, I can't understand.
  My goal is to open and then read a Type_de_fichier file1.txt

  the first word in a specific line in the file1.txt starts with "foo" then when the last word in fichier1.txt ends in 'ZEN'
  write to file2.txt only the analysis section in my where statement.
  I don't know if it's possible, but any guidance will greatly appreciate!

  -Opens a file for writing
  OutFile: = utl_file.fopen ('TEST_DIR', "Out.txt", "w");
  
  -Check the file is open

  EXCEPTION
     WHEN OTHERS THEN
        raise_application_error(-20099, 'Unknown UTL_FILE Error');
  END my_app2l;
  /
  

  What I've done here is added a new Boolean variable. Loop in each iteration after reading one line, we check if the line starts with "foo". If yes then set the Boolean variable and writing out the startup file until we get a line that ends with "ZEN." That way even if there are several paragraphs in an input file starting with foo and ending with ZEN, then those should get copied to the output file.

  Hope this helps,

• Small loop Board problem

  Hey guys I'm reteriving a value using the getitemAt and insertion in a loop

  Now, I want to get this answer and store it in a table. I use additemAt but it doesn't seem to work. (im probably something missing :/) The data area of the table where I want to save is the following

  < mx:DataGridColumn dataField = "Num_Mach" headerText = "Machines" / >

  Here is the code

  for (var x: int = 0; x = 4; x ++) {}

  Servicetimes = int (ProcessAdder.getItemAt (x). Service_Rate)

  for (var NoMachines:int = 1; ValueRow > 100; NoMachines++)

  {

  PartProduced = Servicetimes * NoMachines

  ValueRow = 100 *(ArrivalParts/PartProduced)

  }

  NoMachines = NoMachines-1;

  Gug88,

  Your code is a lot of bad things.

  First of all the variables and functions are NEVER appointed by a capital letter at the beginning - you should always use a lowercase letter at the beginning when naming variables and functions. Things that begin with a capital letter are Classes or constants.

  You should not rely on the value of a variable to loop the loop is completed.

  If you're going to have to add an element to a specific location, you must say where this place is.

  It is not clear if it is an array or ArrayCollection collection.

  You can set a value of just table by processAdder [someIndex] = {Num_Mach:NoMachines};

  For a collection of ArrayCollection is processAdder... addItemAt ({Num_Mach:NoMachines}, someIndex);

  The documentation from Adobe is excellent - spend time looking for how things work.

• Need help with the procedure variable

  Hi guys,.
  
  I try to get the list of the TableName of a specific table and store it in a variable and use this variable to LOOP and remove specific data in the table. Here is my code, maybe that will be clearer...
  
  This procedure within a package
  
  PROCEDURE DeleteData (parCONTR_NBR IN VARCHAR2)
  AS
  v_TableName CMSR_MAPPING. TABLE_NAME % TYPE;
  
  BEGIN
  Extract the names of the tables
  SELECT TABLE_NAME
  IN v_TableName
  OF CMSR_MAPPING
  WHERE TABLE_TYPE <>'W '.
  AND ORDER_SEQ <>' 0'
  ORDER BY ORDER_SEQ DESC
  ;
  
  -Loop on the name of the table
  FOR v_Index in 1... v_TableName.Count LOOP
  -Check that the table name and remove from the respectable table -.
  CASE v_TableName (v_Index)
  WHEN "CMSW_CONTR" THEN
  REMOVE FROM CMSW_CONTR
  WHERE CONTR_NBR = parCONTR_NBR;
  WHEN "CMSW_AMNDS" THEN
  REMOVE FROM CMSW_AMNDS
  WHERE CONTR_NBR = parCONTR_NBR;
  
  END CASE;
  
  END LOOP;
  
  END;
  
  When I run it, I get the following compile on this line error of TO v_Index IN 1.. v_TableName.COUNT LOOP:
  PLS-00487: Invalid reference to the variable 'V_TABLENAME '.
  
  Can someone help with this? What I'm doing wrong here?

  Like this?

  CREATE OR REPLACE PROCEDURE DeleteData (parCONTR_NBR IN VARCHAR2)

     FOR c IN (  SELECT TABLE_NAME v_TableName
                   FROM CMSR_MAPPING
                  WHERE TABLE_TYPE != 'W' AND ORDER_SEQ != '0'
               ORDER BY ORDER_SEQ DESC)
     LOOP
        -- Verify the table name and delete in respectable table --
        --( I always hate when my tables aren't respectable !)
        CASE c.v_TableName
           WHEN 'CMSW_CONTR'
           THEN
              DELETE FROM CMSW_CONTR

        END CASE;
     END LOOP;
  END;
  

  Obviously I don't have your data and do not know exactly what is the whole procedure
  but you could not do?

• Using the loop will decrease performance

  Hello
  Using the loop with a query will decrease performance.
  
  for r_row in (select * from table) Loop
  end of loop.
  
  This is done within another loop for, more cases, it returns a single value.
  It will decrease the performance of the procedure.
  kindly advice...
  
  Kind regards

  Perhaps better understand everything that makes this PL/SQL loop construction.

  PL/SQL is two languages. It's PL (logic programming code) like Pascal, C or Java. You can use a 2nd language in it called SQL. The PL engine will be able to recognize when the 2nd language is used. And it compiles all the things that are necessary for motor PL call the SQL engine, pass the data to the SQL engine and get back data, etc. (compare this with the complexity of the use of SQL in Pascal, C or Java language).

  So what's this loop? The PL engine recognizes the SQL SELECT statement. It creates an implicit cursor by calling the SQL engine to analyze (I hope a soft Parser), then run it.

  As part of the loop of the PL, the PL engine now calls the SQL engine to extract data (lines) of the cursor. With 10g and later, the engine of the PL is smart enough to use the implicit treatment in bulk.

  Before 10 g that he used to extract a line from the SQL engine, make the loop, the next line extraction, the loop, etc. In other words, if there is a 1000 lines to pick up, he'll call the SQL engine after 1000.

  With 10g and later he get a 100 lines, which store in a buffer internal and then make the loop once 100. With a 1000 lines to fetch, it requires 10 extractions in bulk instead of one 1000 rank of extractions.

  These extractions require a change of context - as the engine PL must not out back, and in the SQL engine to extract a line. It is an overhead projector and can become so slow the context switch nothing more.

  And it's the construction of bases for this loop (and most other cursor loops) in PL/SQL.

  The ideal is to reduce the number of context switches. It is an overload that can have an impact on performance.

  What about using a loop in a loop. As 'bad '. This example uses the outer loop to retrieve the data. These data are then used to excite the extraction in internal or nested loop. The outside loop draws data from the SQL engine in PL variables Inside loop drives that same data back to the SQL engine.

  Why? It would have been much faster not to pull and push data between the loops using PL.

  It will be much faster do so only through SQL. Write the two loops as a single SQL statement and have the SQL engine directly driving these loops itself. This is called a JOIN in SQL. And the SQL engine can do not only more quickly, but it has a few algorithms of multiplied can be used which are even faster than a nested loop process (called merge joins, hash joins, etc.).

  Bottom line. Optimize SQL. Reduce to a minimum the PL. *

  Do as much of your data, crunch in SQL as possible. SQL is the fastest 'place' and process the data. No PL (or C/Pascal/Java).

• How can I change a table 1 d to something?

  I am creating a state machine using a 2 X 13 matrix and loop for to transfer a line of binary data to the output lines of the wizard DAQ (see attachments)

  Tutorials, context-sensitive help, Labview help is for me.

  The variable N loop For is a table 1 d.  How can I convert the entire element of 32 bits for the entrance to the function "subset of the table.  How can I change the function of the subset of the Array' expected as input by the DAQ Assistant output to 1 D array?  Why is the variable N of the loop For a 1 d array?

  Nothing you have is correct. First of all, you have not a matrix. A matrix is a special type in LabVIEW. You do not have 2 x 13 is array. You have a table 14 d. I really have no idea how you have created that. What you want is a table of 5 x 13-5 columns for each of your digital lines and 13 for the number of models that you want to run. The loop you have is to display the values of the terminal - i not the n Terminal. When you exit a loop for example, the default is to autoindex the output and create a table.

  To put it simply, create a correct Boolean array and simply connect in a loop with the DAQ Assistant, inside.

  

• Apex 4.0 - field in DB containing CLOB with HTML code

  Hi thare
  
  I'm on Apex Oracle 11.2 4.0.0
  
  I want to display the content of a CLOB in Apex... This is HTML and I want to have the display of the page HTML (as in Explorer) - could be a blank page or within the apex
  the CLOB contains more data then 32K
  
  The file is not mine - so no possibility to change the layout :-)
  
  Any ideas how to make this happen?
  
  concerning

  Edited by: Mettemusens2 2011-10-29 09:18

  Have a region of pl/sql and have a loop to process each line, the html code with a call to htp.p () with the contents of package?

  Select the contents of the clob in a local variable
  to loop through the CLOB line-by-line
  wrap the content in a call to htp.p)

  Thank you
