  Hi Like2Flex,

  The problem is that coldfusion does not see

  list = "a, b, c, d.

  as a list of 9 things you expect. He just sees 4 elements a, b, c and d because Coldfusion does not include two delimiters next to each other.

  A solution to the problem is to manually insert a space between two delimiters that are side by side. Here is an example of such a solution

  
  
  
  length of the list: #listlen (list) #

  Perhaps this example can help:

• ItemRenderer fails values update with sorting applied to the ArrayCollection (dataProvider) collection

  Hi all

  IM updating the ArrayCollection collection which is the source of my list component

  (the email never changes)

  o:Object = {user:"username",email:"emailAdress",state:"number",imageURL="urlToImage"} //This comes from a function and arrives well.
  
  for (var j:int = 0; j < _arcUserList.length; j++)

  Your rendering engine must handle data being null without raising an error.

• How to loop through the values of token

  I am trying to create a simple loop that runs through a bunch of values delimited by commas in a string and add them up. What is the best way to do it?
  
  Currently, my code looks like this
  
  < cfset basevalue = "0" >
  < cfset count = "1" >
  < cfset token = getToken (myString, count, ",") >
  < cfloop condition = "token QNE NULL" >
  < cfset token = getToken (myString, count, ",") >
  < cfset basevalue = basevalue + token >
  < cfset count = count + 1 >
  < / cfloop >
  
  This doesn't seem to work. Any ideas?

  I think that the correct syntax is index = "token". If you have some other delimiter then,

• REGEXP_REPLACE how to loop through the occurrences of a text string variables

  Hello

  I use a 11.g Oracle procedure. I found an example of REGEXP_REPLACE with only two arguments (input and model) and created a procedure based on this example. The Replace function works, but not optimally. I try to use REGEXP_REPLACE to loop on a variable number of occurrences of a text string in a local variable of CLOB.  The string occurs after the text base64 (base64 comma) and before the text "/ > (double quote space oblique superior - only)."  I can do replace it work for a single occurrence, but I can't do it properly in a loop.  These embedded strings include images that were inserted in a rich Apex text field.  This is a rich text field is assigned to the CLOB p_html.

  Declare p_html clob;
  l_image_clob clob;
  l_image_count number;
Begin
p_html := '<p>Some header text base64,one start here and then this is the end one" /></p><p>Some header text base64,two start here and then this is the end two" /></p>';
l_image_count := REGEXP_COUNT(p_html, 'base64', 1, 'i');
If l_image_count > 0 Then
  For i In 1..l_image_count Loop
  l_image_clob := REGEXP_REPLACE(p_html, '(.*base64,)|(" />.*)');
  dbms_output.put_line(l_image_clob);
  -- code to process each occurrence individually.
  End Loop;
End If;
End;

  What I would like to see results of the data are:

  tenure here and that's the end

  two beginning here and that's the end of two

  The results I get are:

  two beginning here and that's the end of two

  two beginning here and that's the end of two

  Thanks a lot for watching this.

  Hello

  From Oracle 11.1, REGEXP_SUBSTR is better than REGEXP_REPLACE for this sort of thing.

  What produces the output you asked for:

  Declare

  CLOB p_html;

  CLOB l_image_clob;

  number of l_image_count;

  Begin

  p_html: = '

  ' Some header text base64, start here and then it's the end "/ >

  Some header text base64, two start here and then it's the end of two"/ >

  ';

  l_image_count: = REGEXP_COUNT (p_html, 'base64', 1, 'i');

  If l_image_count > 0 Then

  For i In 1... l_image_count loop

  l_image_clob: = REGEXP_SUBSTR (p_html )

  , "base64,(.*?)" / > "

  1

  , I - letter i (loop variable), not number 1

  , 'i'

  1

  );

  dbms_output.put_line (l_image_clob);

  -code to treat each case individually.

  End loop;

  End If;

  End;

  /

  The 4th argument to REGEXP_SUBSTR specifies where desired appearance (starting with 1).

  The 6th argument is a backreference. 1 means you want to return all that match the expression starting with the 1st '('. gauche)

• Scripting inDesign: Loop through the layers

  I'm doing a script that will:

  To loop through all the layers in a document.

  Add the layers unlocked in table

  Loop in this table and glue them in place on each layer.

  I don't know how to loop through all the layers.

  Here is my script (I used? to represent where would the loop through all the part of layers):

  JavaScript document

  Set up a table to keep unlocked layers

  var layercollection = [];

  Browse layers and unlocked the layercollection table

  for (i = 0;? i ++) {}

  app.activeDocument.activeLayer = app.activeDocument.layers.itemByName (?);

  If (app.documents [0] .layers.) ([i]). Locked) == false;

  layercollection.push (Layers.itemByName ([i]))

  }

  Loop in table layercollection and paste in place

  for (i = 0; i < layercollection.length; i ++) {}

  app.activeDocument.activeLayer = app.activeDocument.layers.itemByName (tl [i]);

  app.pasteInPlace (); Dough

  }

  Can someone help me complete my script.

  Thank you!

  Did you test them all your solutions in a real world scenario?

  Theoretically, it should work this way (if one ignores that a layer is invisible, too), but even without the problem of invisible layers app.pasteInPlace () prefer to paste into the original layer, if the option "Paste remembers Layers" is checked.

  So I recommend you do the following:

  var oldPasteRem = app.clipboardPreferences.pasteRemembersLayers;
  //uncheck "Paste Remembers Layers"
  app.clipboardPreferences.pasteRemembersLayers = false;
  
  for (i = 0; i < app.activeDocument.layers.length; i++) {
  
      //Maybe the user does not want objects pasted to invisible layers:
      if(app.activeDocument.layers[i].visible == true && app.activeDocument.layers[i].locked == false) {
          app.activeDocument.activeLayer = app.activeDocument.layers[i];
          app.pasteInPlace();
      };
  };
  //Restore the old condition:
  app.clipboardPreferences.pasteRemembersLayers = oldPasteRem;

• Strange behavior on DataGrid with ArrayCollection as a DataProvider collection

  I have a Datagrid with an ArrayCollection as a DataProvider collection, the arrayCollection collection is partially generated by a remoteObject call, the dataprovider seems to work at least until I try to change the field...

  By the RemoteObject, I get only a collection ArrayCollection with the 'ip' field, but the data grid seeks ip, check and recordfields...

  If I add/edit this field new it works, but only under specific condition

  The DataGrid control:

   <s:DataGrid id="datagrid" left="10" right="10" top="136" 
         dataProvider="{listaIPCheck}" bottom="10" requestedRowCount="4">
            <s:columns>
                  <s:ArrayList>
                       <s:GridColumn dataField="ip" headerText="Asset"/>
                       <s:GridColumn dataField="check" headerText="Inventory"/>
                       <s:GridColumn dataField="save" headerText="Salvataggio"/>
                  </s:ArrayList>
             </s:columns>
   </s:DataGrid>
  

  The Script:

     [Bindable]private var listaIPCheck:ArrayCollection; 
  
      private function ro_resultHandler(event:Event=null):void
      {
        listaIPCheck = new ArrayCollection();
        listaIPCheck = ro.getListUpdate.lastResult;
        heap = 0; 
        // Read Below {POINT #1}
        init3(); 
      }
  
  
      private function init3():void
      {
       // Read Below {POINT #2}
       if (heap<listaIPCheck.length)
       {
          // omitted the initialization of the process p
          p.addEventListener(NativeProcessExitEvent.EXIT, onExit);
          try{ 
            p.start(startupInfo);
          }catch(e:Error){}
       }
      }
  
  
  
      private function onExit(e:NativeProcessExitEvent):void { 
          // Read below {POINT #3}
      }
  

  Here is my code, now, as you can see there are 3 lines where I wrote to read below...

  Suppose that to put this simple 'for' instead of the commented (once both) line

      for (var k:Number=0;k<listaIPCheck.length;k++)
      {
        listaIPCheck.getItemAt(k).check = "checkVal";
        listaIPCheck.getItemAt(k).save = "saveVal";
      }
  

  This code still works in 3 points, so at the end of the call, the ArrayCollection collection is always filled with new values, but the datagrid control refresh the items only in the POINT #1 and #2 of POINT

  Why not the Point #3?

  When you get a large number of items in your list, you will probably also find it resets the selectedIndex property and jumps on the first line of data.  It is not automatically updated because the ArrayCollection collection look inside objects to see if they change.  When they change, you must indicate the ArrayCollection collection they changed, call itemUpdated.

• Loop through all the items in a collection

  I need to loop through all the elements of a collection in a VB.NET program that uses the InDesign API. For example, I want to loop through all the pasta spread masters in a document. Here is my sample code:

  Dim I As Integer = 0

  Var MyApp as InDesign.Application = Nothing

  Var MyDoc as InDesign.Document = Nothing

  Var MyPage as InDesign.Page = Nothing

  MyApp = CType (Activator.CreateInstance (Type.GetTypeFromProgID ("InDesign.Application"), True), InDesign.Application)

  MyDoc = CType (MyApp.Documents.Add (False), InDesign.Document)

  With MyDoc

  With. DocumentPreferences

  . PageHeight = "8.5I".

  . PageWidth = "5.5i."

  Ends with

  With. ViewPreferences

  . HorizontalMeasurementUnits = InDesign.idMeasurementUnits.idPoints

  . VerticalMeasurementUnits = InDesign.idMeasurementUnits.idPoints

  Ends with

  If. MasterSpreads.Count > 0 Then

  For I = 0 To. MasterSpreads.Count - 1

  Dim ThisMasterSpread As InDesign.MasterSpread = CType (.) MasterSpreads.Item (I), InDesign.MasterSpread)

  Next I

  End If

  Ends with

  When it runs, I get an error on the last Dim statement which defines ThisMasterSpread. It highlights. MasterSpreads.Item (I) and gives the following error:

  COMException was unhandled: the Member required to the collection does not exist.

  How I managed to loop over all the pasta spread masters?

  Thank you!

  A lot of trial and error, I discovered the answer to my own question: the Collections are 1-based, not 0-based. My statement

  For I = 0 To. MasterSpreads.Count - 1

  should be

  For I = 1 To. MasterSpreads.Count

• JDev 10.1.3.4: How to properly loop through lines of a VO?

  Hello
  
  He is a newbie question. Using JDeveloper 10.1.3.4 trying to loop through the rows of a display object. I'm sure that the VO returns the following lines in this order:
  

  200809
  200902
  200906

  If I use this code (where termsOpen is the instance of VO):
  

  while (termsOpen.hasNext()) {
     System.out.println(termsOpen.getCurrentRow().getAttribute("Term"));
  }

  It turns out to be an endless loop and I get "200809" displayed on the console ever. The API said that hasNext() 'does not move the current line. A book indicates that the pointer is initially at line 0. I wonder why it prints the first row. If the code is changed to:
  

  while (termsOpen.hasNext()) {
     Row currRow = termsOpen.next();
     System.out.println(currRow.getAttribute("Term")); 
  }

  But now I get only the last two lines displayed on the console and do not get to see the first line:
  

  200902
  200906

  What's wrong?
  
  Thanks for the help!

  You can also use VO.getEstimatedRowCount () to get the number of rows, and browse all lines:

          long size = termsOpen.getEstimatedRowCount();
          for (int i=0; i
  

• Loop of Datagrid and update database

  Hello

  What I would do:

  I have a datagird, users can change the data. When a key is pressed, the entire data grid is saved. I have a service that I can use to update each row of data to a database table, but how do I loop through each line? Can a code sample suggestion someone?

  Thanks again!

  Brian

  OK, found the answer in the following link, for those stuck on the same thing. This can be closed.

• loop through XML

  I have the below XML and i want to loop through this XML and put the value in an array
  
  <Subproductdetails>
    <Subproduct id="1" name="AA" /> 
    <Subproduct id="2" name="BB" /> 
  </Subproductdetails>

  say, I declare a number table num_arr, I want the num_arr to be filled with id: 1 and 2.
  is someone can please show me how this is done in pl/sql
  
  Thank you.

  Hello

  If you have 10.2 or higher, try this:

  DECLARE
  
   TYPE num_arr_type IS TABLE OF NUMBER;
   num_arr num_arr_type;
  
   v_xml xmltype := xmltype('
    
    
  
  ');
  
  BEGIN
  
   SELECT id
   BULK COLLECT INTO num_arr
   FROM XMLTable(
    '/Subproductdetails/Subproduct'
    passing v_xml
    columns id number path '@id'
   );
  
  END;
  /
  

  For versions prior to 10.2 (and with the support of xmltype), use the following SELECT statement instead:

  SELECT extractvalue(column_value, 'Subproduct/@id')
  BULK COLLECT INTO num_arr
  FROM Table(
    XMLSequence(
      Extract(v_xml, '/Subproductdetails/Subproduct')
    )
  );
  

• How to fill a datagrid with a web service result which is an array?

  I know how to fill a DataGrid to a CF of the web service that returns a query result. But what happens if I want to my CF component to run a query, then massage the data and back-is not a query - but a picture from the web service.
  
  Seems my two dimension table because ColdFusion has no column name, I need to create on the CF side name-value pairs or the side Flex. BTW, I prefer to use mx:webservice and not remoteObject.
  
  Any ideas on the best way to fill a datagrid from an array?
  
  Thank you.

  (Sorry for the previous double post).

  A colleague found the answer for me. I hope this saves someone else from 5 days of anquish!

  When a ColdFusion component returns an array of structures (not the result of a query), redesign the table as an arrayCollection collection throws an error.

  IT DOES NOT WORK:
  acSpeeds = new ArrayCollection (wsSpeeds.oneNode.lastResult);

  THIS WORKS!
  acSpeeds = wsSpeeds.oneNode.lastResult;

  It seems that a table generated by ColdFusion structures is already a collection arrayCollection 'official '!

  Hope this helps someone.
