  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) #

• 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)

• 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 >

  This doesn't seem to work. Any ideas?

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

• How to navigate through the file to the blackberry playbook using Tablet blackberry OS for Adobe Air SDK

  Hi all

  How to navigate through the file to the blackberry playbook using Tablet blackberry OS for Adobe Air SDK.

  And also I want to download this file on the server.

  Help me by providing examples of coding.

  Thanks in advance.

  With respect,

  Here are some tips to help you get started.  It all depends on the terms that you use for your search.  For the first, I would use "adobe air browse file."  For the second, I start with only a variation as "adobe air download file" and then adjust according to the first results.

• loop through the layers defining the lock and visibility

  I need to loop through the layers in the active document and the value of the properties of the layer is false or true.  I tried to create a loop using a method 'for', but it doesn't seem to work. I have renounced the method 'for' because I kept running into a problem.  I have set all layers with these settings just the odd ones (2,4,6, etc.). Here is sample if it was written.

  myLayer = myDoc.layers var [2];

  myLayer.visible = false;

  myLayer.locked = true;

  myLayer = myDoc.layers var [4];

  myLayer.visible = false;

  myLayer.locked = true;

  myLayer = myDoc.layers var [6];

  myLayer.visible = false;

  myLayer.locked = true;

  myLayer = myDoc.layers var [8];

  myLayer.visible = false;

  myLayer.locked = true;

  I have 208 layers, so doing it this way would be way to long. Any help would be appreciated.

  After I wrote this and tested, I saw that Carlos had already answered, but I thought that I would post it anyway. Carlos KNOWS how much I love JS... ;-)

  One difference is that, since it was not clear to me which layer you talk like layer #1, I started at the bottom of the scale.  I hope this helps.  -TT

  var aDoc = app.activeDocument;
  var lc = aDoc.layers.length;
  for (var i = 2; i <= lc; i+=2) {

• 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;

• Loop through the list in flex 4 conclusion d buttons

  Anyone know how to completely recursively loops through the list in flex 4 by pulling the bodies of buttons.  This way I can apply my effects for buttons on the screen at the same time?

  You just create a subclass of button that has the desired effect and use it throughout your application.

• loop through the list in flex 4

  I want to loop through the list and apply the following code to each button, the checkbox and the descent down in my application

  mouseOver = "animateHover ('theComponentID').

  How is that possible?

  Hello

  This should do what you want, you must add the eventlistener now your animated can be run from the th event handler.

  protected function button1_clickHandler(event:MouseEvent):void

  {

  for (var i: Number = 0; i<>

  {

  var obj:Object = this.getElementAt (i);

  If (flash.utils.getQualifiedClassName (obj) is 'spark.components::Button')

  {

  (obj as Button) .addEventListener (MouseEvent.MOUSE_OVER, onMouseOver);

  }

  If (flash.utils.getQualifiedClassName (obj) is 'spark.components::CheckBox')

  {

  (obj as CheckBox) .addEventListener (MouseEvent.MOUSE_OVER, onMouseOver);

  }

  }

  }

  private void onMouseOver(event:MouseEvent):void

  {

  animateHover (event.currentTarget);

• How to loop through DataGrid (ArrayCollection, DataProvider collection)

  I need to loop through a collection ArrayCollection DataProvider or DataGrid (not sure which is best) so that I can insert information in a database through ColdFusion.

  The data grid has three columns: ID, item and quantity.  I have a table that contains these same fields.  The DataGrid control is pre-filled with a list of items.  The user can then enter the quantity of items in the DataGrid.  I then want to store this information in my table.  In ColdFusion, I would accomplish this through CFLOOP, however, in Flex I want to loop through the data grid so that I can get all the items and the quantities that the user has updated.

  I guess I have to do a loop in ActionScript, but I don't know how to do that.  Can anyone provide a suggestion and example code?

  Thanks again!

• How can I print the results of my research?

  I have more than 3000 DWF files in my search results. They are located in different folders on our server. How can I print the results of my research?

  This means that nomo did not read your question carefully.

  I think Directory printer Karen will do what you want.  3000 files is a lot of paper.  You can download Cute PDF Writer and save the output to a PDF instead - at least until you get the options sorted...
