Problm with StringBuilder

• OOM playing with StringBuilder and String

  Hi list

  I want to check the diff between concatination partial string using stringbuffer (pmd create a suspicion around the sign + inside the stringbufffer.append).

  now I write follow the example of code:

  public class StringBuffererf

  {

  Public Shared Sub main (String [] args)

  {

  nrLoops long = 100000000;

  StringBuffer sb = new StringBuffer();

  Start long = System.currentTimeMillis ();

  for (int i = 0; i < = nrLoops; i ++)

  {

  If (I / 1000 == 0)

  {

  SB = new StringBuffer();

  }

  SB. Append ("asd1" + "asd2" + "asd3" + "TSA4" + "asd5" + "asd1" + "asd2" + "asd3" + "TSA4" + "asd5");

  }

  System.out.println ("time:" + (System.currentTimeMillis () - start));

  Start = System.currentTimeMillis ();

  for (int i = 0; i < = nrLoops; i ++)

  {

  If (I / 1000 == 0)

  {

  SB = new StringBuffer();

  }

  SB. Append ("asd1");

  SB. Append ("asd2");

  SB. Append ("asd3");

  SB. Append ("asd4");

  SB. Append ("asd5");

  SB. Append ("asd1");

  SB. Append ("asd2");

  SB. Append ("asd3");

  SB. Append ("asd4");

  SB. Append ("asd5");

  }

  System.out.println ("time:" + (System.currentTimeMillis () - start));

  }

  }

  an interesting around this code is: partial + operations within a stringbuffer is faster then use each time an addition.

  But if I increase the number of loops I get an oom.

  IMHO I don't expect this, because with

  If (I / 1000 == 0)

  {

  SB = new StringBuffer();

  }

  I have however, that release the object and free memory also.

  I have sore around it and I've got the cause of the oom.

  suspicion and or advanced are welcome

  Best regards

  Dietmar

  The expression ' I / 1000 ' is not what you think it does.

  You test not concatenation of the way you wrote it because the compiler, not the virtual machine does concatenation.

  Presumably, you understand the difference between StringBuffer and StringBuilder.

• Z10 battery blackBerry with Z10 strange problem

  I got a 100-3 10.1.2019OS Z10. I had no problms with her. Every now and then the battery becomes hot and sinks quickly.

  I encountered a strange problem. All of a sudden, my battery with a minimum life isn't quite a day. I have ony 1 app running, guru of battery that monitors battery. I have two spare batteries. I tried to change the batteries and it makes no difference.

  As I said, I have had this since it was released here in the United States and generally get about 2 days with my use. and I made NO changes, no new apps.

  Any thoughts?

  See my thread on battery drainage Z10 suddenly more quickly.

  I found Gmail as an issue. If you configure try to delete the account and do a battery pull. See if it works.

  I had a similar problem for the last 2 days and Gmail has proved to be the culprit.

• G62: START PROBLEM

  my laptop can not start correctly it brings a black screen with an option, press Esc botton for starting, and indicates a problm with cooling fan. When I press the start menu when I say recover or no matter what option he says "no boot device - insert boot disk and press any key any." Please help because I dnt have any disk now.

  You can restart the device and keep tapping F10 at startup to access the BIOS screen and then do a DPS to test the hard drive first. If the hard drive test is passed, there will be no error codes and indicate that the drive is good.

  If the hard drive test is passed then change the order of boot in the BIOS, so that the hard drive is the first boot order.

  Then try to start and see if it works.

  If this still doesn't work, you may have to reinstall the operating system, but at this point, you will lose all data.

  You can insert the disc bootable windows 7 and restart the device and keep tapping the F9 key and then select DVD player

  to boot from the DVD drive. This procedure will reinstall the operating system completely.

• Problem calling LabVIEW DLL with c#

  Dear all,

  I compiled a few DLLs in LabVIEW and called these DLLs using c#.
  I'm having trouble passing in strings and arrays as input and output of the DLL.

  Whenever I try to view the string I have entered in a dialog box (this part is written in LabVIEW DLL), a LabVIEW message dialog box appears and the program just stuck there.

  Whenever I try to enter a string or an array to the dll, Microsoft Visual Studio would display "attempt read or write protected memory. It is often an indication that other memory has been corrupted. »

  I attached the vi and also the c# .sln file.

  Can you guys please advise where am I wrong?

  Thank you very much.

  You must allocate strings and arrays of output!

  private void button1_Click (object sender, EventArgs e)
  {
  output string;
  int [] value;
  StringOutput ("A", "B", exit, 3, value, 4);
  }
  }

  Your variable output and value must be preallocated to ensure storage of 3 items respectively. 4. and since you want to receive the C string that you need to increase this to 4 characters terminated by a NULL value.

  String in c# is also a not a C string of object pointer. You must declare the StringOutput() function as follows:

  [DllImport("SharedLib.dll",CallingConvention=CallingConvention.StdCall, Charset=CharSet.Ansi]internal static extern int StringOutput(StringBuilder A, StringBuilder B, out StringBuilder StringOutput, int sizeString, out int[] output, int sizeArray);
  

  Then call like this:

  StringBuilder output = new StringBuilder(4);int[4] array = new int[4];
  
  StringOutput("A", "B", output, output.Capacity, value, value.Length);
  

  Please note that I'm not a pro in c# and usually do not do much in it. Also that this code has not been tested or updated at all, so probably contains some errors. He however point you in the direction of where to look further.

  What you need to understand, is that the C DLL that you created in LabVIEW has a so-called unmanaged interface. This means c# is not able to know how to manage the memory for the parameters at all and you have to do everything yourself, where the obligation to explicitedly initialize variables output and table with a block of memory préallouée.

• Report - a list of all instances of FglAM with versions &amp; type o/s

  I have not found any KB article, community or previous Commons on this subject.

  The Web Console. Host agent dashboard lists all FglAM ' assets/market' with their OS version/type & version FglAM.
  I have difficulties to create a report that lists all of the FglAM that have already been created with their versions & type o/s.

  FglamClientInstance & RemoteClient toplogies have "null" displayed for the field version so don't know where we can get this value.

  This simple query lists all FglAM and the last updated field:

  sb = def "<>
  #! FglamClientInstance # .getTopologyObjects () .each {}

  SB< 'host:="" '="">< it.name =""><   '="" last="" updated:'="">< it.lastupdated=""><>

  }
  return of sb

  RESULT:
  Host: alvbchan2k8-562 (fglam) last updated: 2013-06-20 10:07:10.375

  Host: loriw2k8r2f55 (fglam) last updated: 2013-06-20 10:07:10.375

  Host: loriw2k8r2f555 (fglam) last updated: 2013-06-20 10:07:10.375

  Examination of the application of the hosts of the Agent dashboard, seems, it gets these values from root of the Administration Server. all_agent_hosts.

  See attachment.
  So that won't work because we are interested in all THE FglAM whether they are active or not.

  Any help appreciated to generate a report similar to the table edge, but for all FglAM that have already been deployed with version & type o/s; No active and active.

  Thank you
  Rick

  Currently on FMS version 5.6.7, version FglAM is not stored in the FglamClientInstance or the RemoteClient types of topology.  FAM-5227 was generated to request the FglAM version to be stored in FglamClientInstance.

  The code following groovy lists currently active FglAMs and their versions:

  output = new StringBuilder()

  EOL = System.getProperty ("line.separator");

  fglams = server. RemoteAgentManagementService.findAllRemoteClients)

  fglams.sort ({IT. GetHostName()})

  output< "hostname,="" ,="" type,="" version,="" os="" name,="" os="" version,="" os="" arch"=""><>

  {fglams.each ()}

  output<>

  output< ",="" "=""><>

  output< ",="" "=""><>

  output< ",="" "=""><>

  output< ",="" "=""><>

  output< ",="" "=""><>

  output<>

  }

  return output

  RESULT:

  I have read and watched videos about the creation of an object of a class and calling its method in a different class. I'm still confused on how to do it properly. By using the code below if someone can explain how to properly call the method of objects from my hand.

  Huh? You have NOT posted any 'hand' or any 'method of objects '.

  If you need help with the code, you need to view the code.

  The Java tutorials has dozens of trails "Classes and objects": what they are, how to create and how to use them.

  https://docs.Oracle.com/javase/tutorial/Java/javaOO/classes.html

  1. create an instance of a class

  2. call to one or more of the public methods of this class

  If the class has public static methods, you don't need to create an instance first.

  I suggest that you work your way through these tutorials. They include the WORKING example code.

• ADF showPrintablePageBehavior with action

  Hello
  
  I use successfully the component of ADF showPrintablePageBehavior inside a command button to display a printable version of an existing page. It is simple and works well:
  

  <af:commandButton text="Print Me" id="cb1">
      <af:showPrintablePageBehavior/>
  </af:commandButton>

  If I understand the documentation that the addition of this element of a control commandButton to removes example any event button action server-side:

  Note that the component of command will not be forwarded to an action on the server event (the event is canceled), but there will be a request to the server to get the printable page.

  I have a specific use case where I want to call an action side server in addition to render the printable page. For example, let's say I want to know when a user has selected the print function (to check or update some State-side server to indicate that the page has been printed in fact).
  I'm struggling to implement this scenario unfortunately.
  I tried:
  1. the element 'action' or 'actionListener"normal... faithful to documentation commandButton control, it does not - and should not work.
  
  2. ask to another button on the page to complete the server-side function. When the user clicks on this button and the action side server was carried out, I tried to simulate a click on a button of a second button (hidden) on the page that contains the actual component showPrintablePageBehavior. Basically structured as follows:
  

  <af:commandButton text="Print Me" id="cb1" action="#{backingBean.myAction}">
  </af:commandButton>
  
  <af:commandButton text="Hidden print" id="cb2" visible="false">
      <af:showPrintablePageBehavior/>
  </af:commandButton>

  Action server side (backingBean.myAction), I tried two ways to simulate the click on the "Print" button hidden in order to make the printable version:
  1. queue a Java ActionEvent (hiddenPrintButton is "binding" on the bean with success):

   ActionEvent ae = new ActionEvent(hiddenPrintButton);
   ae.queue();

  2 inject the Javascript to call the second button:

  FacesContext fctx = FacesContext.getCurrentInstance();  
  StringBuilder script = new StringBuilder();  
  script.append(String.format("var hiddenPrintButton = AdfPage.PAGE.findComponentByAbsoluteId('%s');\n", hiddenPrintButton.getClientId()));
  //script.append("??");  Logic for simulating a "click"
  Service.getRenderKitService(fctx,ExtendedRenderKitService.class).addScript(fctx,script.toString()); 

  In the 'logic to simulate a click', I tried different options (ActionEvent, AdfCustomEvent), but I can't seem to successfully simulate a click.
  
  In the version of Java, the 'action' defined for the hidden print button is executed if I set one, but only that - I actually need the printing behavior must be executed.
  
  Am I on the right track here... ? There may be a much easier way to achieve what I want? I unfortunately don't have a lot of experience of the ADF yet.
  
  Thanks in advance for any comments or reviews.

  Hello

  see this example:

  http://www.Oracle.com/technetwork/developer-tools/ADF/learnmore/11-client-listener-169135.PDF

  What you need to do:

  1. place an af:clientListener on the command button that launches the printable page
  2. define an af:serverListener next to this command button and wire up to a bean managed on the server
  3 write JavaScript to call the server listener (so the reference sample)
  4. do not call 'Cancel' on the event function JS argument

  This will allow you to send a notification on the server when the event is called

• Dealing with small buttons

  Hello
  
  I am creating a spinner control (i.e. a TextField followed by two small button objects that provide the feature to increase/decrease the value of the textfield).
  
  I implement using a HBox containing a TextField and a VBox, where the VBox contains two buttons (btnUp and btnDown).
  
  I can't figure out how to make the small buttons (I want them to be half the height of the text field).
  SetMaxHeight() implementation does not work. The only way I found to make them smaller is to use setScaleY (0.5), but it does not help the page layout because it is not considered during calculations available.
  
  What would be the best way to develop this type of arrangement of controls?

  Hello

  I think you'll find that your problem is related to the style of the button. In particular the 'fill' and perhaps also the font size (if you use a text).

  Try this:

  TextField field = new TextField("Test");
  spinner.setCenter(field);
  
  VBox buttonPane = new VBox();
  
  String buttonStyle = new StringBuilder()
          .append("-fx-padding: 0 6 0 6;")
          .append("-fx-font-size: 6;")
          .toString();
  
  Button upButton = new Button("u");
  upButton.setStyle(buttonStyle);
  VBox.setVgrow(upButton, Priority.ALWAYS);
  buttonPane.getChildren().add(upButton);
  
  Button downButton = new Button("d");
  downButton.setStyle(buttonStyle);
  VBox.setVgrow(downButton, Priority.ALWAYS);
  buttonPane.getChildren().add(downButton);
  
  spinner.setRight(buttonPane);
  

  Note the VBox.setVgrow is supposed to make controls stretch to fill the space as far as I know, but it doesn't seem to work. I usually use the MigLayout so I'm not too familiar with it. If you need more help on this, probably best to post again.

  See you soon,.

• StringBuilder insert question

  Hello
  I'm trying to insert integer values into a StringBuilder object. With single-digit values, it's OK but when I (example 14) two-digit values it is interpreted as 1 and 4 and he started in the StringBuilder as two separate values 1 and 4 instead of just 14.
  How can I stop this from happening?
  

   static void perfect( int number ){
  
  StringBuilder sb = new StringBuilder();
  
  for( int j = 1; j <= number - 1; j++){
                      if( number % j == 0 ){
  
                           sb.insert(0, j);
  .
  .
  .
  .
  .
  }

  As jverd says what you need to do is insert a comma before each value except the first.

  loop {
      if content is not empty {
          insert comma
      }
      insert value
  }
