• Creating Windows dvd with the problem of the "invalid class string".

  When you try to burn a file to a dvd using windows dvd creation, I received a message 'tring class not valid' when burning, and the disc has been ejected. What does the message mean? How to fix?

  Hi KEVINQUACH,

  1. When you have the startup problem?

  2. you remember to make changes to the computer before this problem?

  3 - is this happen when you try to burn any type of particular file?

  You can check out the following link and try the steps suggested by Aziz N Support Engineer on December 2, 2009, and check if this may help.

• Failed to create the DVD__Invalid class string

  This happens in Windows DVD maker and has just started a few days ago, I can't think of any modification of the software just before that, I installed the recommended Codec pack but it was a few weeks ago

  The "invalid class string" problem: it can be solved by repairing the DirectShow filters in the system. Some guys do it manually by editing the registry. But there is a simpler solution: "Codec Tweak Tool" oder "Filmerit. (The first is one of the last and can be used with Windows 7 without problem).

  Codec Tewak Tool (Version 4.9): http://www.codecguide.com/download_other.htm

• Developer SQL 4.1.1 connect returns "invalid connection string format.

  The "invalid connection string format" error is returned, while trying to connect, you use sql developer 4.1.1.19, using 1.8.0_51 JDK on Win 7 x 64 environment.

  The powers of the exact same connection, on the same OS Win 7 x 64, a product without any errors using sql developer 4.0.2.15, using the JDK 1.7.0_80

  Credentials were basic, by default, the name of the Service (not SID) and no special authentication.

  This problem is replicated when it is installed on a different platform to Win 7.

  Screen attached.

  You say you have no non-alphabetic characters, but see this previous discussion (a hyphen was the problem) and see if any of Jeff's suggestions work for you: connection error after upgrade to 4.1

  I also read another post (non - developer SQL) where a symbol (@) in the password was a problem, but that may not apply to your case.

• class string for the name operation

  Hi, suppose I have three classes with names like

  enemy1

  enemy2

  enemy3

  and a table enemyIndices = [1,1,2,2,3,1,2] or something like that.  Is it possible to compose on the fly class names so that I can write something like

  for (i = 1; i < = enemyIndices.length; i ++)

  {

  var className:String = enemy + i;

  var obj:Object = new className(); / / to create enemy1 etc.

  } ?

  Of course, I can use if... else statement to achieve this

  if(i==1)

  new enemy1();

  another if (i == 2)

  new enemy2();

  another if (i is 3)

  new enemy3();

  You can use (I assume you mean to use the numbers in the table, not only its length)...

  for (var i: uint = 1; i<= enemyindices.length;="">

  {

  var ClassRef: Class = Class (getDefinitionByName ("enemy" + String (enemyIndices [i])));
  var obj: * = new ClassRef();
  addChild (obj);

• Invalid parameter string

  Hello

  I often validation error when I want to import into parameters in a child workflows.

  In my workflow, a string is initialize with a number (strValue). I checked that the value is correctly set (System.debug (strValue)).

  Later in my workflow, he launched a child workflow that needs this string (strValue). At this point, I get fatal errors:

  • Workflow failed: parameter not valid (s)
  • For the "strValue" parameter validation error: required field not defined
  • Workflow failed: validation error

  If I hard code the "strValue ' in the attributes of the tab in my workflow, I don't experience the error. Even if I turn "strValue" as an entry workflow and enter it in the presentation view when I submit my workflow to start.

  Any ideas how to avoid these mistakes?

  Thank you for your contributions.

  Fred

  OK, validation issue when running on subworkflow. My previous statement was valid for a validation running on the parent workflow.

  Include a System.log (System.getObjectType (strTaskID)); in the box of scriptable before subworkflow that fails.

  If it does not come as a string, you will have to climb when assigning the value with the addition of + "";

• "unicode" is an invalid connection string attribute

  Didn't someone say Oralcle that all strings in .NET are in Unicode?
  
  Anyone know of a workaround for this problem?
  
  -Eric
  US Army

  Hello

  The fact that .NET strings are unicode has nothing to do with the connection string attributes. Look at your connection string, you probably 'unicode = true' in computing and Oracle ODP doent have a connection string attribute called Unicode. Does Microsoft data provider. Oracle doesn't. For a list of valid connect string attributes, check it [docs ODP | http://download.oracle.com/docs/pdf/E10927_01.pdf].

  Well, I have looked at the registry and do not find the CLSID of InDesign. Yes, you are right, InDesign saves not com library.

  But what do I do to install the COM library manually? Use the regsvr32.exe command, but what dll should I use to register?

• Invalid loadjava on DB - classes can't recompile

  Hello

  I don't know what happened past that I get invalid classes on my database...

  I downloaded JAR file several months previously with loadjava and recompile classes side database and all worked ok...

  Now, classes are invalid...

  

  I tried to drop all classes and repeat the procedure with java support... with:

  c:\loadjava-force - genmissing - grant r_inis_prod-user insurance2/i@MYDB-verbose C:\iText-2.0.7.jar

  

  If I look in the toad I get: 398 invalid classes...

  

  How to "recompile" this course?

  I also used this approach:

  select 'alter java class '||'"'||object_name||'"'|| ' compile;' 
    from user_objects 
    where status <> 'VALID' 
    And object_type ='JAVA CLASS';
  

  But it does not work...

  Thanks for any help...

  OK, if you don't see anything obvious in the list of errors, next step is to start from a resolution of error and to go up the hierarchy of dependencies to find the classes root causes the error.

  for example

  If you start from "com, lowagie, text, anchor" class, you see, it is not resolved because depends on one of the classes of is not resolved either: "com/lowagie/text/plants/ElementFactory.

  Now, you can search for why "com/lowagie/text/plants/ElementFactory" is not resolved and so on.

  This could take a while if you do it manually, but you can also use a hierarchical query combining views USER_ERRORS and USER_DEPENDENCIES.

  Notice that it contains a 'short' class names also there (stuff like ' / 84c41b8b_SomeName').

  To get the name of long correspondent (or), use DBMS_JAVA.longname () function (resp. shortname()).

• String class

  Why print the String object in class displays the content of this variable and do not String@H=hashCode (). ?
  
  

  wbecause, if you print an object reference, and then uses toString() to print message internally, which is originally written in object class with ' getClass () .getName () + ' @' + Integer.toHexString (hashCode ()) "logic." but in the class String ToString is overridden to print the contents of the string.

• Features of LabView string StartsWith as in c#?

  Hi all

  in c# (.NET) there is a good class: String

  There, it is possible for example to get information, if the string startswith one substring special.

  Is that what this possibility in LabView? Y at - it these LabView vi, which offers this feature? (Excerpts)?

  So I ask you:

  So I ask you:

  I want to create a switch/case (structure-case) block in labview for this code:

  This can be done already with the structure of the case, you can make simple analysis in the case selector, which takes a string as input.

  Type in the case of the first case "XYZ".... "XYZ".

  Enter the next case "DEF".... "DEF ~".

  Next is the empty string, the default value.

  How does this work:

  The "XYZ...". "XYZ ~ ' matches all strings that begin with XYZ and any ascii value after the ~ is the highest value printable 7-bit ascii for that catches all the other characters.

  Option 2 is parse (there is expression reg very good vi in the channel palette) the string and create if a corresponding to the value of the integer can habdle unique integers in the structure of the case.

  There are so many ways to do it without a wrapper for the string .net class, I have provided some quick methods

• Is it possible to get the class of a generic Type?

  I wanted to male a generic class to map the static fields of a class, of the same type (think < tt > < /tt > Color.RED) and the only way I could find to get the class fields / was passing the literal class to the constructor. Is there a way to do this with a constructor with no arguments?

  package darrylbu.util;
  
  import java.lang.reflect.*;
  import java.util.*;
  
  public class StaticFieldMap<T> extends HashMap<String, T> {
  
    @SuppressWarnings("unchecked")
    public StaticFieldMap(Class<T> clazz) {
      Field[] fields = clazz.getDeclaredFields();
      for (Field field : fields) {
        if (field.getType() == clazz) {
          try {
            put(field.getName(), (T) field.get(null));
          } catch (IllegalArgumentException ex) {
            ex.printStackTrace();
          } catch (IllegalAccessException ex) {
            ex.printStackTrace();
          }
        }
      }
    }
  }

  Since the usual question what about the reflection is usually "why?" I am including a possible use case.

  import darrylbu.util.StaticFieldMap;
  import java.awt.Color;
  import java.util.Map;
  import javax.swing.*;
  import javax.swing.event.ListSelectionEvent;
  import javax.swing.event.ListSelectionListener;
  
  public class ColorMapDemo {
  
    public static void main(String[] args) throws Exception {
      SwingUtilities.invokeLater(new Runnable() {
  
        @Override
        public void run() {
          new ColorMapDemo().makeUI();
        }
      });
    }
  
    public void makeUI() {
      final Map<String, Color> colorMap = new StaticFieldMap<Color>(Color.class);
      String[] data = colorMap.keySet().toArray(new String[] {});
      final JPanel panel = new JPanel();
      final JList list = new JList(data);
      list.addListSelectionListener(new ListSelectionListener() {
  
        public void valueChanged(ListSelectionEvent e) {
          if (!e.getValueIsAdjusting()) {
            panel.setBackground(colorMap.get((String)list.getSelectedValue()));
          }
        }
      });
      list.setSelectedIndex(0);
      panel.add(new JScrollPane(list));
      JFrame frame = new JFrame();
      frame.add(panel);
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.setSize(300, 300);
      frame.setLocationRelativeTo(null);
      frame.setVisible(true);
    }
  }

  Thanks Ben. Sorry - what a j.l.r. type?

  A java.lang.reflect.Type all j.l.Class implements this interface. What you have to do is this.getClass () .getGenericSuperclass () of the class, the cast of the Type returned to ParameterizedType, call getActualTypeArguments() and the result would be the color class object.

  I don't really have the "requirements" being just a hobby programmer. But the other day I wrote a program to display all "named colors" of javafx.scene.paint.Color (there is a lot more than in java.awt.Color) and I felt that a utility class/method can be useful to have around.

  Well, the technique described above is somewhat fragile, but achievable. If it is 'just' for a project, you need to decide for yourself if it's the right person.

  Composition of favour over the legacy; StaticFieldMap should implement the map and delegate to an internal hash table.

  Must do it, thanks. I guess that your reasoning behind the advice is that the class is a card but is-not-a HashMap. Am I wrong?

  Correct, and the implementation details would be so leaked into your public API if it were to inherit from HashMap.

  Or do you think it would be better/cleaner to do this with a utility method?

  Yes. However, playing with the API j.l.r.Type is a good learning experience. I remember trying to use seriously and then thinking changed his mind. However there are cases where it makes sense to use [1].

  With greetings
