• Script to generate XML files... problem with null values

  Hello everyone,
  
  I come here with a question that troubled me for some time. I have a script which I run in SQLPLUS every now and then to generate an XML file.
  
  Problem is that the data that must be in XML format are not allways <>NULL and I need to hide empty tags < / tag >.
  
  I'll post my script below and if you could help me with it, it would be really great!
  
  Thanks for reading!

  XMLForest that does exactly:

• Problems with null dropTarget

  Hey guys.  I'm testing now on different things and I'm doing a box that, when one of the two bullets fell inside and causes the text of the appropriate color display (i.e. redBall appear 'RED', 'BLUE' poster blueBall when left in the box).  I went through a few different ways to do it, but now I am using dropTarget.  I find that when I put in the box using the code below, everything works fine, but if I drop anywhere off the beaten path, I get an error message «cannot access a property or a method of a reference object null.»  I'm assuming that I'm just formulating this second statement conditional dropTarget (if (e.currentTarget.dropTarget == null)) wrong, but I don't know how to fix it.  Here's the code for cancelling feature that I use:

  function drop(e:MouseEvent):void
  {    
      e.currentTarget.stopDrag();
              
      if (e.currentTarget.dropTarget.parent == box)
      {
          if (e.currentTarget == redBall)
          {
              wordBox.addChild(redText);
          }
          if (e.currentTarget == blueBall)
          {
              wordBox.addChild(blueText);
          }
      }
      if (e.currentTarget.dropTarget == null)
      {
          if (redText.stage != null)
          {
              wordBox.removeChild(redText);
          }
          if (blueText.stage != null)
          {
              wordBox.removeChild(blueText);
          }
      }
  }

  function drop(e:MouseEvent):void{        e.currentTarget.stopDrag();
  
  if(e.currentTarget.dropTarget!=null){    if (e.currentTarget.dropTarget.parent == box)
      {
          if (e.currentTarget == redBall)
          {
              wordBox.addChild(redText);
          }
          if (e.currentTarget == blueBall)
          {
              wordBox.addChild(blueText);
          }
      }
      if (e.currentTarget.dropTarget == null)
      {
          if (redText.stage != null)
          {
              wordBox.removeChild(redText);
          }
          if (blueText.stage != null)
          {
              wordBox.removeChild(blueText);
          }
      }
  }}

  Table: digital_val

  Actual result: expected to A         B

  case If c1 = "san2" then c2 B

  of digital_val

  I'm more curious why, when you select 2 rows, you expect a result of row?

  WITH digital_val

  AS (SELECT 1 AS 'Sno', 'San1"C1, c2 FROM DUAL 11)

  UNION ALL

  2 SELECT AS 'Sno', 'San2"C1, c2 FROM DUAL 22)

  SELECT CASE WHEN c1 is "San1" THEN END AS A c2.

  CASE WHEN c1 = "San2" THEN END AS B c2

  OF digital_val;

  With no other input, if you select 2 rows, you get 2 rows.  One of the other solutions use a max function, but is this really what you want, does not specify?

• Satellite U400-PSU44E - problem with XP drivers

  Hello
  I have the Satellite U400-PSU44E. It was the Vista Home Premium pre-installed spirit, but I had to install XP Pro.
  Under XP I have problem with installing the drivers. If I try to install driver sound I get info that the media is not found, even with the modem driver. I tried to install the electricity utility of Eve - in the last step of the installation, I get an error, and this error ia´m getting always ia´m try to uninstall this version adding utility / Removo programs.
  HARD drive protection utility I also install the Cana´t - I Dona´t don't know if this feature is supported in my Toshiba, but if this pilot is being Satellite U400 PSU44E I think it should be.
  ChipSet drivers and BIOS I installed as the first.
  I downloaded only the drivers from the web site of Toshiba (ce.computers.toshiba...) for win XP.

  Any suggestions?
  Please, please, help me!

  PS: is there some suggested order of installing the drivers for this model?

• Problem with driver with Agilent 6031 A feeding

  Hello and goodmorning,

  I tried to develop my first application of cvi in which I need to use a power supply (model Agilent 6031 A). I first use direct command of GPIB and I managed to make it work, but with some difficulty, due to the fact that sometimes orders are missed.

  So I downloaded the driver from the website of OR, and I tried to implement in my code. I found a problem with the first statement, the init it. Here is my code:

  ViPSession InstrumentH;
  
  ...
  
  ...
  ...
  
  All = hp6xxxa_init ("GPIB0::5:INSTR", VI_ON, VI_ON, 1, & InstrumentH);

  After running the above code, I found in 'All' value '-1073807339 "and InstrumentH is equal to NULL."

  Any idea and advice would be much appreciated.

  P. S.

  There is a way, as in Labview, to find the explanation of the error Code?

  Found the problem. Food must be set of SCPI commands on the old controls ARP using "SYST:LANG".

• Callback thread will not end, problem with CNVDisposeData?

  I have a problem with a thread of reminder on a RT system. I work with CVI 8.5 on the pc and the engine Runtime 9.0 on the RT system.

  I use a client-server architecture, the client writes data to a network 1 d variable, the server is informed via a connection to the Subscriber and frees a callback function. My problem is, this callback function is launched in another thread (not the main thread) and is not over. I reduced the problem as much as I could, right now the only thing I do in my callback is to have the CNVdata. The problem occurs when the callback is released, create and destroy the connection to the Subscriber without calling the callback does not lead to any problems.

  The real problem with this, is that when my program ends, there are still threads running on the RT system, which can lead to problems later (I have a multi-day-measure application that crashes always at the same time, so I must really have it clean) to the left.

  I'll try to post a snippet of code to make sure you get what I'm doing (all in the main RT, for simplicity):

  CNVCreateSubscriber (serveurnom, dataCallback, NULL, NULL, 3000, 0, & dataSubscriber);

  While (!.) () RTIsShuttingDown &! error)
  {
  ProcessSystemEvents();
  Sleep (100);
  }

  CNVDispose (dataSubscriber);

  ProcessSystemEvents();

  CloseCVIRTE();

  My point basically looks like this:

  Sub CVICALLBACK dataCallback (void * handle, CNVData data, void * callbackData)
  {
  CNVDisposeData (data);
  }

  When I look at my son when running, I see from the callback thread, when I'm inside, but it's still there afterwards. In addition, what is CNVDisposeData supposed to do? The variable 'data' retains its value even after disposing. I don't see any change at all.

  I would appreciate any comments or ideas, I have tried to solve this problem for a few days and really don't know what else I could try!

  Yes, for the network variables, callbacks are called on a dedicated worker thread. Do not calls to ProcessSystemEvents - network variable reminders will be always called. You must call CNVFinish at the end of RTmain to ensure that the worker thread comes out cleanly. If your variable is hosted (configured) on RT target, then the worker thread can continue to operate even after the call to CNVFinish - I recommend that you host the variable on another machine, said the Windows host.

• Problems with timing of analog input PCI-6111

  I'm reading the analog input of a PCI-6111, who receives a square signal of 1 KHz with a cycle of 50%.  I put the sampling frequency to 1 MHz and wait until the data points are 1 usec outside.  When I check the signals received, it appears that the duration of each period of the square wave is 1.22ms instead of the expected 1.0 ms.

  The following is a snippet of what I tried:

  int NUM_SAMP = 10000;
  DAQmxCreateTask("",&mTaskHandle);

  DAQmxCreateAIVoltageChan (mTaskHandle,

  "(/Dev1/AI0","",DAQmx_Val_Cfg_Default,-10.,10.,DAQmx_Val_Volts,null); "

  DAQmxCfgSampClkTiming(mTaskHandle,"",1000000,DAQmx_Val_Rising,DAQmx_Val_ContSamps,NUM_SAMP);

  DAQmxReadAnalogF64(mTaskHandle,NUM_SAMP,10.0,DAQmx_Val_GroupByScanNumber,mDataBuf,NUM_SAMP,&numRead,);

  Can you tell me what I am doing wrong?

  Hello SNL_NB_1167,

  A good place to watch code you know works would be the finder of the example.  "" "" Open the finder example and navigate to hardware input & output "DAQmx" analog measures ' tension ' ContAcq - IntClk.prj

  Run this code and see if you get the same results.  If so, then we would know that it's a hardware problem and not a problem with the programming.  If you see the correct behavior, then you have code that you can shape your out of.  I hope this helps.

• Problems with video recording

  Hello

  I have some problems with the video recording on the BlackBerry.

  On the BB 9700 my application crashes when I try to stop recording. The file produced
  the app is empty.
  On BB 9800 I have the same problem unless I have explicitly defined the video resolution, but
  in this case, the resolution of the resulting video is different from what I

• Problem with the ObjectListField

  Hello

  I have problems with the method getSelectedIndex() ObjectListField.
  Supposedly, when there is no index selected, it returns-1. But how come it always returns the index of the last element?

  To illustrate, I created my own dialog that has similar functionality to the "device window select" Bluetooth BB application. I have an ObjectListField and a Cancel button. What I did simply, is to change the label of the button to show the selected index. I have attached my sample code below.

  public class MyDialog extends dialog
  {
  private ObjectListField m_list;
  private ButtonField m_btn;

  public MyDialog)
  {
  Super ("Select Device:", null, null, 0, Bitmap.getBitmapResource ("bluetoothIcon.PNG"), Manager.FOCUSABLE);

  m_List = new ObjectListField();
  m_btn = new ButtonField ("Cancel", Field.FIELD_HCENTER);
  m_List.set (new String [] {"first", "second"});

  Add (m_List);
  Add (m_btn);
  }

  protected boolean navigationClick (int status, int time)
  {
  m_btn.setLabel (Integer.ToString (m_List.getSelectedIndex ()));

  Returns true;
  }
  }

  Can someone help me on this problem? Is there something wrong with my code, or is the buggy API? All I want to do is to return an index of-1 if there is no selected item in the list.

  Also, I tried the isFocus() method to check if the list is being concentrated, it always returns false even if the list is OBVIOUSLY being focused. I'm running out of options on how to determine the solution to this problem. Help, please!

  Thank you very much.

  @jacylan - I do not use isFocus() to determine if the ListField is net.  Take a look at the following code, I think that with this, you can force-1 when the ListField is not the point.

      protected boolean navigationClick(int status, int time)
      {
          int selectedIndex = m_list.getSelectedIndex();
          boolean listInFocusOption1 = false;
          if ( this.getLeafFieldWithFocus() == m_list ) {
              listInFocusOption1 = true;
          }
          boolean listInFocusOption2 = false;
          if ( m_list.isFocus() ) {
              listInFocusOption2 = true;
          }
          m_btn.setLabel(Integer.toString(selectedIndex) + ":" + listInFocusOption1 + ":" +listInFocusOption2);
  
          return true;
      }
  

• Problems with Connector.open

  I'm having a problem with the re-login to a HttpsConnection once a failure has occurred. I send a message to a php site that works 100% OK. However, if I drop the receipt when sending at the reception is retrieved Connector.open no reconnect not (even after a long wait). and gives a "java.io.InterruptedIOException: connection Local has expired" exception. The issue is not corrected until the phone is rebooted.

  I use MDS to transport and endpoint certificate has a valid certificate (does not Self-signed). Before I drop the front desk, a message is sent correctly and using the console creates the following log entries:

  [0,0] * start sending:

  [0,0] SSL :-> CH

  [0,0] SSL:<>

  [0,0] SSL:<>

  [0,0] SSL:<>

  [0,0] SSL:<>

  [0,0] SSL :-> CKE

  [0,0] SSL :-> CCS

  [0,0] TLS :-> F

  [0,0] TLS:<>

  [0,0] VMISVt = 0, h = 1a7b, id = d15a33128dfbb5d9

  [0,0] VM:LNTDa = validation, t = 1, p = D8Mobile

  [0,0] * open Stream:

  [0,0] * sending data:

  [0,0] * server response: 200

  [0,0] * Flushing bos

  [0,0] * input stream of Flushing

  [0,0] * Flushing DOUT

  [0,0] * Flushing HC

  [0,0] TLS:<-Alert -="" level="1" description="">

  [0,0] * emptied all

  Once the reception has been abandoned and valued, the connection begins to open the SSL session and shows the following:

  [0,0] * start sending:

  [0,0] SSL :-> CH

  He gets Nevers to: SSL [0,0]:<>

  After the time-out period, it then returns the exception

  IO exception: java.io.InterruptedIOException: Local connection timed out after ~ 15000

  [0,0] * Flushing bos

  [0,0] * emptied all

  Of course the connection is instantiated is no longer so I can't even try his end on the connector at this stage. I also see the following in the MDS newspapers - although I'm not sure its related:

  <2012-01-18 10:42:03.921="" gmt="">:[528]:::

  What follows is a version of my code. All this code runs since a thread to work constantly in the loop.

  HttpsConnection hc =null;

  InputStream is =null;

  Dout OutputStream =null;

  ByteArrayOutputStream Bos =newByteArrayOutputStream();

  byte [] res = null;

  VR;

  {

  System.

  HC = (HttpsConnection) Connector.open (url + ";" ConnectionTimeout = 15000; deviceside = false');

  "Credentials of string = this._username +": "+this._password;"

  byte [] encodedAuthorization = Base64OutputStream.encode (credentials.getBytes (), 0, credentials.length (),false,false);

  () hc.setRequestProperty

  "Authorization", "basic" +newString (encodedAuthorization));

  () hc.setRequestProperty

  'Content-Type', ' multipart/form-data; Boundary = "+ getBoundaryString());

  dout = hc.openOutputStream ();

  dout. Write (postBytes);

  dout. Flush();

  this._responseCode = hc.getResponseCode ();

  dout. Close();

  is = hc.openInputStream ();

  int ch;

  while ((ch = is.read (())! = - 1).

  {

  Bos.Write (ch);

  }

  RES = bos.toByteArray ();

  }

  catch (IOException ioe) {

  System.out.println ("* IO Exception:" + ioe.toString ());

  this._responseCode = 0;

  RES = null;

  }

  catch (Exception e)

  {

  System.out.println ("* send the Message of the Exception:" + try ());

  this._responseCode = 0;

  RES = null;

  }

  Finally

  {

  VR;

  {

  if (bos! = null) {

  Bos.Close ();

  }

  if (is! = null) {

  is. Close();

  }

  if (dout! = null) {

  dout. Close();

  }

  if (hc! = null) {

  HC. Close();

  }

  }

  catch (Exception e2)

  {

  System.out.println ("* Message send Exception 2:" + e2.toString ());

  }

  }

  of return ;

  }

  I tried on 8700,8900 and 9700 device simulators. I am running JRE 5.0.0 and MDS v4.1.4

  Any help or suggestions will be appreciate - I spent nearly a week debugging it and its slowly driving me crazy!

  Thank you

  Try to use the factory connections if you are targettin devices in 5.0 or above, it might solve the prob.

• openDatabase problem with O.S. 6 simulators

  I use the following code

  a simulator of O.S. 6 9780.

  the performance of a var d = new Dataset(); the code does not work after alert ('b');

  IF I run this code on a simulator of O.S. 5 8520 code will run successfully

  What is the problem with 6 O.S. and openDatabase... I thought it was a HTML5 / feature OS 6?

  Car simulator! device = real. It is not specific to the RIM is: no mobile simulators are not enough for the final testing. They are just not quite representative of the actual device. They are narrow, often very close, but I guarantee that you will always find new bugs not known on a simulator, and the Simulator will not always behave as a real device. It's just the nature of the simulation.

  It is easier said than done, but you really need to test on devices real as much as possible before the production.

• Problem with criteria, GPS, with plugins Eclipse Simulator.

  Hello

  I work with Eclipse and I do an application that I use the GPS API.

  My problem is that always the LocationProvider.getInstance (new Criteria()) return null.

  The Simulator model 8830, GPS location is a location's the JDE 4.5.0

  Do I need any specific configuration?

  Thank you.

  It is a problem with the BlackBerry itself Simulator.  You can test the GPS using another Simulator model BlackBerry (for example BlackBerry 8310).
