  How to get the color of the text information in the text layer?  I mean using scripts Photoshop, Version of Photoshop CS 8.0

  The color textItem is readable for me in VBS Note expects the activeLayer be a textLayer and displays the HexValue of the color of the text.

  Option Explicit
  
  Dim appRef
  Dim docRef
  Dim textItemRef
  Dim artLayerRef
  Dim textColor
  
  Set appRef = CreateObject( "Photoshop.Application" )
  
  appRef.BringToFront
  
  Set docRef = appRef.ActiveDocument
  Set artLayerRef = docRef.ActiveLayer
  Set textItemRef = artLayerRef.TextItem
  Set textColor = textItemRef.Color
  
  MsgBox textColor.RGB.HexValue
  

  And returns the color of the text if the text is the same color. But if the text is more than a color textItem.color returns only the color of the first text range.

• How to get the RGB value of a pixel in a psd document using scripting Photoshop

  Hi, guys!    Does anyone know how to get the RGB value of a pixel in a psd document using scripts in Photoshop?  I myself have missed for a long time and could not resolve. I am very happy to hear your voice as soon as possible!

  Here is an example...

  var originalUnits = app.preferences.rulerUnits;
  app.preferences.rulerUnits = Units.PIXELS;
  var doc = activeDocument;
  var Colour1 = GetHexColour(eyeDropperRGB(1,doc.height-1));
  var Colour2 = GetHexColour(eyeDropperRGB(20,doc.height-5));
  var Colour3 = GetHexColour(eyeDropperRGB(40,doc.height-14));
  alert("Colour 1 = " +Colour1 + "\rColour 2 = " +Colour2 + "\rColour 3 = " +Colour3);
  var decColour = eyeDropperRGB(40,doc.height-14);
  alert("Red = " +decColour[0] + "\rGreen = " +decColour[1] + "\rBlue = " +decColour[2]);
  app.preferences.rulerUnits = originalUnits;
  function GetHexColour(reqHex){
  var out='';
  for(No in colours = reqHex){

   }
  return out;
  };
  function eyeDropperRGB(x,y) {
   var x2 = x + 1;
   var y2 = y + 1;
   var out = new Array(3);
   activeDocument.selection.select([[x,y], [x2,y], [x2,y2], [x, y2]], SelectionType.REPLACE, 0, false);
   for(ch in list = ["Red", "Green", "Blue"]) {

• How to get the color and stroke of ComboBox

  I would get the selected color and stroke selected ComboBoxes to print these values as strings in an .ini file to save the settings.

  Here is my example http://s24.postimg.org/q59kivgxh/Z055.png where I have a scene with ComboBoxes.List

  The list of colors is an ObservableList in the classroom

  public class ComboBoxColorCellFactory {
    
   public static  ObservableList<String> colorList = FXCollections.observableArrayList(
           
  "White", "WhiteSmoke", "GhostWhite", "Ivory", "MintCream", "Beige", "Transparent", "Seashell", "Snow", "Honeydew", "FloralWhite", "Cornsilk", "BlancheDalmond","Wheat", "AntiqueWhite", "NavajoWhite"); 
  

  and the list of race

  public class ComboBoxLineCellFactory {

  In my previous version of swing, I used to get these values in this way (PriceRetracementIni is the class with the statements of private fields and define and use the get methods).

  PriceRetracementIni.setColor1(Integer.toString(((Color)jComboBoxColor1.getSelectedItem()).getRed())+ "|" + Integer.toString(((Color)jComboBoxColor1.getSelectedItem()).getGreen())+ "|" + Integer.toString(((Color)jComboBoxColor1.getSelectedItem()).getBlue()));
  
  

  PriceRetracementIni.setStyle1(ComboLineTypeConstants.getStrokeArray((BasicStroke)jComboBoxStyle1.getSelectedItem()));
  
  

  PriceRetracementIni.setFontStyle(jComboBoxFontStyle.getSelectedItem().toString());

  Thank you.

• How to get the ID of a single data centre and the Cluster

  Hello

  We have a product we need get the detail of data centers, Clusters, the Esx host and all Virtual Machines of a Virtual Center. And keep it in sync with the VCenter. I use a thread that queries the VCenter every 5 minutes and retrieves the data.

  We use Java VI SDK 4.0 for this.

  At the present time I am able to read all the details using PropertyCollector. But once a data center is renowned for my application, it is similar to a fact that a data center with the old name has been deleted and a data center with the new name has been added. For this reason, when data center is renamed, I remove entities for the former my application Esx host and adding new features to the ESX hosts in new data center. It causes a lot of unwanted things.

  So, I want to go get some unique Id of the dataCenter and Cluster, so that when a cluster/datacenter is renamed, uniqueId is always the same and my app will be able to know that it is just a change of name. And entities for ESX/VirtualMachine will be kept.

  Please, help me to know the unique id of the cluster/datacenter.

  Thank you

  Deepak

  Yes, there are supposed to be unique UUID generated by vCenter or ESX (i) and if you have not manually mux with values. The UUID is guaranteed to be unique within a given instance of vCenter.

• Persistent for the subtraction of the background image collection (how to get the maximum value of each pixel in a series of images IMAQ)

  Hi all

  I have a system of LabVIEW which takes advantage IMAQ tools and features of the Vision Development Module.  A useful feature that I put in place is to be able to take a snapshot of the video stream and then subtract this single image among the subsequent images.

  What I want to do is to collect a series of images instead of one, and then create a unique image of these frameworks is just the maximum value of pixels in each pixel (a bit like a display persistent).

  It would probably be very easy to be implemented by converting the image to a table and then by doing math number on the table and then turning into an image, but I hope that someone here may know how to use the IMAQ/VDM tools to do this in a way more compact.

  Thank you very much

  How about using Max comparison IMAQ operation?

  Hello

  I would like to use my laptop (satellite pro M40x-115) as a DVD player. But when I connect my laptop to my TV, I get only a black and white display. I tried to solve this problem by installing the latest driver for my graphics card but it has not changed at all.

  How can I solve this?

  Greetz El Mariachi

  Hello

  Have you checked the graphics settings? The settings of the TV must be set to PAL (most of Europe).
  In addition, you should check your TV device if it s can receive the S-video signal.

• How to get the list in a single column in a query

  Hello.
  
  I wonder if there is a way to get a query (no pl/sql code) a list of columns with a separator between them.
  
  I know I can get that without separators with an expression of cursor:

  SQL> with test_table as (
    2  select 1 col1, 'a' col2 from dual
    3  union
    4  select 1 col1, 'b' col2 from dual
    5  union
    6  select 1 col1, 'c' col2 from dual
    7  union
    8  select 2 col1, 'a' col2 from dual
    9  union
   10  select 2 col1, 'c' col2 from dual
   11  union
   12  select 2 col1, 'd' col2 from dual
   13  union
   14  select 2 col1, 'z' col2 from dual
   15  )
   16  select col1, cursor (select b.col2 from test_table b where b.col1 = a.col1 order by b.col2) col2_list from test_table a
   17  group by col1
   18  /
  
        COL1 COL2_LIST
  ---------- --------------------
           1 CURSOR STATEMENT : 2
  
  CURSOR STATEMENT : 2
  
  C
  -
  a
  b
  c
  
           2 CURSOR STATEMENT : 2
  
  CURSOR STATEMENT : 2
  
  C
  -
  a
  c
  d
  z

  But the result I want is (by using the separator ';'):

        COL1 COL2_LIST
  ---------- --------------------
           1 a;b;c
           2 a;c;d;z

  I don't know how to manage a cursor expression without using a pl/sql function block. Can it be done using analytical functions?
  
  Thanks in advance.

  Hello

  This is called 'aggregation of chain.
  This site:

  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:2196162600402

  shows different ways to do this, including the SYS_CONNECT_BY_PATH solution which gave Blushadow.

  I got a lot of use of the first solution on this page, the function defined by the user STRAGG, that you can copy.

  Once you have installed STRAGG, your query is simply

  SELECT    col1
  ,         STRAGG (col2)     AS col2_list
  FROM      test_table
  GROUP BY  col1;
  

  The query above do not put items in a particular order.

  On Oracle 10 (and more) you can have a similar function, the WM_CONCAT (property WMSYS), already installed.
  WM_CONCAT is not documented, so you can't use it in your Production applications.

• How to get the result of a single line in several columns

  I have a scenario where I asked five different columns in a table and it would still look back one line.
  
  So, for example: the query would be

   Select user1, user2, user3, user4 from table1 where tblkey= 2 

  So, this would mean 1 row with the value of their respective areas.
  
  In my code, I have a common function I can call to send an email to the list of people (User1, User2, user3, user4).
  
  So rather than call this function each time for each user, is there a way I can display the output to 4 different rows and use the loop For to call this function only once.
  
  In this way, the loop For running 4 times (if not nulls for all users) and call this function of e-mail.
  
  Really, I'd appreciate if someone could give me an idea of this scenario.
  
  Thank you

  If the number of columns is fixed you may be able to use this:

  SELECT  DECODE
          (
                  RN
          ,       1,USER1
          ,       2,USER2
          ,       3,USER3
          ,       4,USER4
          )       AS USERS
  FROM    TABLE1
  CROSS JOIN (SELECT ROWNUM RN FROM DUAL CONNECT BY ROWNUM <= 4)
  WHERE   TBLKEY = 2
  

  This UN-pivot results.

  Here's an example of it in action:

  SQL> CREATE TABLE TABLE1
    2  (
    3          TBLKEY  NUMBER
    4  ,       USER1   VARCHAR2(1)
    5  ,       USER2   VARCHAR2(1)
    6  ,       USER3   VARCHAR2(1)
    7  ,       USER4   VARCHAR2(1)
    8  );
  
  Table created.
  
  SQL> INSERT INTO TABLE1
    2  SELECT  ROWNUM
    3  ,       SUBSTR(OBJECT_NAME,1,1)
    4  ,       SUBSTR(OBJECT_NAME,2,1)
    5  ,       SUBSTR(OBJECT_NAME,3,1)
    6  ,       SUBSTR(OBJECT_NAME,4,1)
    7  FROM    ALL_OBJECTS
    8  WHERE ROWNUM <= 10;
  
  10 rows created.
  
  SQL> SELECT * FROM TABLE1 WHERE TBLKEY = 2;
  
                TBLKEY USER1      USER2      USER3      USER4
  -------------------- ---------- ---------- ---------- ----------
                     2 I          _          U          S
