  When I set the exception inside the loop, as above, the procedure seems never to end, and I end up getting a 'NOWAIT' error when I try to remove the table or something like that.

  The code works fine if I remove the 'START' just after the loop and also out of the exception within the loop, but I want to be able to specify what's wrong with each record rather than deal with the correct records and then stop after that it is a record that has, for example, 9 values in a column that accepts only 6.

  Can anyone help with this?

  Thank you

• How to continue a loop after rear roller called a Transaction in SOA

  Hi all

  I have major bpel processes that call an external web service that returns the Recordset.

  iiterate through the game, I need to remember the each file in topic QA.

  and ack each record after their storage in AQTopic. If the ACK does not I should roll back the previously inserted record of QA.

  I have divided into two parts of the XA transaction using "checkpoint();".

  Based on the status of the receipt, I called throw with Rollback transaction activity, I handled that by using catch everything in scope.but even after this process ends is not an iteration in the loop.

  I used XA Datasource.

  Please suggest me.

  Thanks René.

  Hi PuneetRekhade,

  Thanks for your suggestion.

  After receving the ack = success, before storing the recording in the AQ if the system breaks down data would no longer exist in AQ's or database for the external web service.

  the recording should not be lost at any cost.

  in my case, if the system crashes before sending the data to QA, nothing happens because I wouldn't send the acknowledgement to the external web service.

  Thank you

  Raj.

• How to know the size of a node until it is displayed?

  Hello
  
  I am trying to anchor two nodes (say A & B) near the top of a component to anchor such as B set out below A. To do this, I provide an offset to anchor for the order of B, who must be the height of node A. However, as the scene containing has not yet been demonstrated, the method for the node getWidth() returns 0 (zero). Since the size node A is calculated based on the content, I can't hard-code size. So I am at a loss how to provide the height of node A in a dynamic way.
  
  Please do not hesitate to ask me to clarify the matter, if I myself not clear enough.
  
  Thank you.

  You have more than two answers, but if you continue in this way, the links can help you:

  VBox A = new VBox();
  A.widthProperty().addListener(new ChangeListener() {
  
              public void changed(ObservableValue ov, Number t, Number t1) {
                  AnchorPane.setTopAnchor(B,  t1);
              }
          });
  

  I like the answer which recommends another provision.

• How to make the loop audio clips in the first or elsewhere

  HOW CAN I DO AUDIO LOOPING CLIPS IN THE FIRST OR ELSEWHERE?

  None of these answers are correct.

  My brother found this thread, looking for help and left in frustration, asking for the answer instead.

  Kevin Monahan response is only semi-finished.

  Here's the full answer:

  Looping a video or audio clip on the timeline, right-click and select 'nest...".

  Name the nest, what you please.

  Now, double-click on nested clip you just created. This allows to enter the nested sequence.

  NOW you can select the clip, copy and Paste several times. (Just keep hitting CTRL V, and the read head automatically moves forward to place the next clip.)

  Return to the main sequence.

  Now you can use the selection tool to extend this nest as much or as little as you like.

  It is a far superior method, because a nested sequence is a SINGLE ELEMENT that can be resized, given effects, moved, lengthened and shortened very easily.

  While you are using the term 'video' incorrectly.

  loadMovieNum(this._url,0);

• How to use the loop to commit every 1 M folders?

  Oracle 9i
  40 M records must be insert the table. You will need to validate every 1 M. But I don't want to loop every recording and validation. I like select commit and records of 1 m and then select another 1 M, then validation; How to do? use the save point?
  
  Appreciate any ideas.
  Thank you
  S.

  You can perform this anonymous help block by using a loop and listen but it not a good idea to commit after 1 million or 100 k you put more load on your system and the performance will be declining.

  If you want to display in a loop there a loop button in the Source and the program monitor.

  Otherwise, you need to put a dozen or more times on the timeline to make it loop.

• BlackBerry Smartphones how out of the loop of ID

  My old BB Bold died on me - and I mean dead. No discount to zero and even the Desk top manager doesn't recognize it. I bought a Torch 9800 has changed the SIM card and it worked fine, until it came to the e-mail set up. I could remember my user name but not the password. I duly clicked 'forgot password' and back came the answer password sent to your B'berry. Probably at my "BOLD" dead. Because I can not access my mail to set the address on the new torch, because I need the password, I'm stuck here. I went to the site of B'berry ID, punch in the username and they too want to sent me a password to my address B'berry. I tried my service provider to get the password. Once more sent to my address mobileemail. They do not provide access to my address mobileemail, web-based as well as possibility of password recovery was released. I tried to go back and recreate a new user ID. No problem until I come to the e-mail address, how I threw because the address is already in use - no surprise, except that I can't use it.

  Is there someone who can suggest a way out of this? Short of renouncing the B'berrys and the purchase of an another smart phone providers.

  PVW

  Thank you very much for your promt reply. I tried your advice/suggestions, but without success. I can only conclude that your point about the dangers of use BIS for the was/is the real pitfall BBID enamel only. My provider has been particularly useless and made disparaging remarks about the problems caused by the so-called B'berry accounts 'package '. The megastore where I bought my BB Bold faithful a few years before, is more about B'berrys and were unable, rather reluctant to help. Europe becomes a wilderness of B'berry. So, I think after 10 years of happiness of Blackberry and three days of effort wasted his defeat in face of time and switch to another system.

  Thanks again for your help. You can't win them all; as the proverb says.

• How to continue the drawing with the pen tool

  Hello

  Let's say that I start to draw an image with the pen tool. Something happens 1/2 through the work of track and I need to stop the trace. How I later come back and start the trace of my last point and continue to the end. Now, all I get is new anchor points and lines that do not join the original track. Thank you

  To resume adding segments to a pre-existing open path with the pen tool:

  1. Hover over the endpoint of the path. A slash mark appears next to the cursor.
  2. Click on the endpoint.
  3. Continue to add the anchorPoints.

  It is not necessary first to select the path (but it should be).

• How to hide the part of my page until my survey is submitted?

  I have a web page that has a poll on this subject.  When users send the survey, I want content on the page to show them the correct answers for the poll.  (They will vote on what they think a dog breeds).  It can be found at http://animalhospitalofkennewick.com/dna.php.  The survey is on the left.  The content to the right of the voting that begins with "Good Job!" needs to be hidden until they voted in the poll.  All this content is located in the "hidden" div  How can I do this?  I tried "display: none;" in CSS but then it never occurs later.  Help!

  Jeannette

  I had another look at the site and now get a database error.

  To answer your question, I used the buttons as an example of how to trigger hide and show fuction. This trigger can be place d on a div or a link. In your case, you will place the trigger on everything that makes the answers to questions. This part, I still don't see because of the error messages. This is the piece of code that triggers the fuction

  onClick = "show () '"

  and can be placed anywhere. Instead of a click, the trigger can be a passage of the mouse, a mouseOur, an onChange (when a value has been changed) etc.

  You can declare an another begin... end with its own exception handler to catch the error.

  BEGIN
  FOR rs
  (SELECT 'my select stmt' FROM DUAL
  )
  LOOP
  NULL;--if there has error update error info to ERR_LOG table and continue loop
     begin
     null;
