How do to this chain operation looks simple but causing a lot of time to do :)

Hi all

I have a very large chain, i.e. the soap xml response send by server that I read once connected to the server using http, now the problem is that I need to create a Document out of it and analyze what is simple but the answer I get server requires many replacements of string as example 1) replacing "<" with "<"  2)="" replacing="" ">"="" with="" "="">" etc before creating a document out of it now there are many such replacements in the sending of the response from server that takes a lot of time. 5 minutes on the emulator. So my question is how do? Is there a native method to replaceAll occurrences of a substring in a string or while I can use or is there another good way? Please let me know thx.

Thank you

We took over a project done by someone else, and they were doing exactly what you do.  Here is their source, which I think is more effective that you give it a try if you want.

But be aware that I have never used or tested this code.

I guess you pull that string to the center of your SOAP response.  It has been encoded XML.  So you can do what we did in this case and wrap the string as a data element in an XML element and then use the XML parser to get the actual data, which feed us an XML parser again to get the actual data.  XML is already set up to deal with these characters, so it was more effective than the approach to replace.  Actually to be honest, it wasn't the reason we exchanged, that as part of the parser XML meant we were convinced it was done correctly.

 public String replaceAll(String source, String pattern, String replace) {
        if ((source != null) && (pattern.length() > 0)) {
            final int len = pattern.length();
            StringBuffer sb = new StringBuffer();
            int found = -1;
            int start = 0;

            while ((found = source.indexOf(pattern, start)) != -1) {
                sb.append(source.substring(start, found));
                sb.append(replace);
                start = found + len;
            }

            sb.append(source.substring(start));
            return sb.toString();
        } else
            return "";
    }

  • Probably very simple, but cause me problems

    Hello, I'm going to try to keep it as simple as possible increase the chances of someone who can help me - thank you if you can!

    I have a movieclip: allows you to call, abc

    I have a second clip, lets call him it 123

    123 has the value alpha = 0, so it can't be seen.

    When the mouse passes over abc, I 123 change alpha 1 and when it the mouse is off abc 123 to alpha 0 new

    Here's how (and it works):

    123.alpha = 0;

    ABC.addEventListener (MouseEvent.MOUSE_OVER, manageMouseOver);

    function manageMouseOver(event:MouseEvent):void {}

    .alpha 123= 1;

    }

    ABC.addEventListener (MouseEvent.MOUSE_OUT, manageMouseOut);

    function manageMouseOut(event:MouseEvent):void {}

    123alpha = 0;

    }

    It works very well.

    However, I would be able to switch to 123 and click...

    In this case however, the mouse has been moved off the coast of the abc and 123 go to alpha 0.

    It is just a simple menu to my eyes...

    With a mouse on showing a second movieclip and a mouseoff hide...

    How can I make this work?

    Many thanks if you can help!

    What you need to do, is to have your MovieClip called nested inside abc 123. In this way when you hover over abc and 123 is made visible, you can move your mouse to 123 without triggering the ROLL_OUT event (as long as it has no space empty between the content of abc and 123 mc). Also, you can eliminate some of this code with a switch statement:

    var 123MC:MovieClip = abc.123;

    123MC.Alpha = 0;

    123MC.addEventListener (MouseEvent.MOUSE_DOWN, onMenuClicked);

    abc.addEventListener (MouseEvent.ROLL_OVER, onMouseInOut);

    abc.addEventListener (MouseEvent.ROLL_OUT, onMouseInOut);

    private void onMouseInOut(e:MouseEvent):void

    {

    {Switch (e.type)}

    case No. MouseEvent.ROLL_OVER:

    123MC.Alpha = 1;

    break;

    case MouseEvent.ROLL_OUT:

    123MC.Alpha = 0;

    break;

    }

    }

    private void onMenuClicked(e:MouseEvent):void

    {

    {Switch (e.currentTarget)}

    case 123MC:

    if(e.currentTarget.alpha == 1) {}

    doSomething();

    }

    break;

    }

    }

    Note you will also need to either add/remove the earpiece to event MOUSE_DOWN because people can still click on it when it is invisible otherwise.

    Is it possible to disable this notification?  I've made a few changes in group policy limit some startup programs.  Now, I suppose that this appears when the program tries to start.  Really irritating.  Maybe there's something in group policy to restrict the notification?  Then there will be another notification telling me that this notification applies?  Laughing out loud!

    When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

    -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
    -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
    -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

  • CoreFoundation.ddl was not found. Why is there no place on Microsoft sites that specifically tells a user how to correct this registry.

    Why a windows user has to pay a third party to correct this problem?  Responses to this problem should be easily and readily found so that people who have purchased products with Microsoft operating systems can easily solve the problems themselves.  Where is the answer I need on how to correct this error without having to pay someone.  It seems to me, you have already paid the system once, you shouldn't have to pay a second time to solve a problem with her.  It's very frustrating trying to find the help you need without turning around and around the company who wants to take your money to fix.  Microsoft needs to tell me how to solve this problem.   PLEASE, I BEG YOU.

    First of all, it was an honest typo, I was not looking for the wrong thing.  I have big problems getting Quick Time to work on my computer.  I have re - down loaded, download Itunes, downloaded the package combined download of two of them.  Nothing will work.  Here is a list of all the error messages I received in the last two days:

    Quick Time #0 error, please make sure that QuickTime is properly installed on this computer
    The plug is not properly initialzie
    I tunes of assistance was not installed correctly.  Please reinstall Itunes Helper.  Error 7
    Errors occurred during the installation of the updates.  If the problem persists, choose Tools, only download and try to install it manually.
    And finally...
    Application has failed to start because CFNetowrk.dll was not found.  Reinstalling the application may fix.

    So, I register QuickTime, iTunes and Windows problems.  So where can I find a way to correct my mistake of registry which cost no money and has download their parties _ who pay you and it still does not work.

    I don't know if it will work, but it has helped other people who have problems with installation of these products.  Save the download to your desktop.  Right click on the Setup icon, and then click Run as administrator.  I know that you are probably already connected as long as administrator but believe it is sometimes the case for some reason that I don't understand.

    There may be a problem with another Apple program interfere with installation of itunes (specifically the itunes help). http://discussions.apple.com/thread.jspa?threadID=2256415.  Here's the gist of it:

    Uninstall the Application Support from Apple, iTunes and Quicktimes (if these, two are displayed as installed).

    (From this moment until reinstall us Application Support, Apple, QuickTime nor Safari 4.0.4 will able to run.)

    Then, we'll remove all the leftover program files and folders.

    (1) open the "disk" Local (c) or according to drive it your program files are stored on.
    (2) open the "Program files".
    (3) with the right button on the iTunes folder (if it still exists), then select 'delete '.
    (4) return to 'disc' Local (c) or according to drive it your program files are stored on.
    (5) open the folder "Program Files (x 86)".
    (6) with the right button on the iTunes folder (if it still exists), then select 'delete '.
    (7) staying in "Program Files (x 86)", open the "Common files" folder.
    (8) open the folder "Apple."
    (9) with the right button on the Apple's Application Support folder (if it still exists), then select 'delete '.

    Now, empty your Recycle Bin and reboot the PC.

    Reinstall Phase

    After restarting the PC, do not open other applications. Disconnect from your network or the internet. Turn off all your security (firewall, antivirus and anti-spyware) software.

    Now start the installation in a right-click on the iTunesSetup.exe file and you downloaded earlier and then clicking Run as administrator.

    Re-enable all security software before you reconnect to your network or the internet.

    ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

    For the iTunes is not install properly and to do please ensure that QuickTime is installed correctly on this computer errors, try to repair your .NET Framework 3.5 SP! application by going to start / Control Panel / programs and features / .NET Framework 3.5 SP! Click on the program and click on repair or uninstall.  When you are prompted, click Repair and let it run.  You won't have to restart.

    --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

    The FPR application failed to start because CFNetowrk.dll was not found.  Reinstalling the application may fix.  Make sure you have all updetes installed Windows - and I mean all of them (except for device drivers).  Do a manual check and install whatever it is, it comes with and then do another manual check and do the same thing and this follow up until no new update is presented and confirms that you are using the SP2 for Vista (Start / computer / system properties and it should say SP2).  Otherwise, manually install SP2 and rerun through the exercise of updates (or check it out before you start making updates).

    -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

    For the plug-in has not initialized properly, make sure that you use version 7.4.1.14 QuickTimes or most recent - there is a known issue with older versions of work with Vista, but they claim to have the answers with this version.  If you've tried for awhile, you will have an older version.  I download and save on the latest desktop and make sure it is as stated above.  I also re - download and save on the desktop iTunes very it in case theres a similar problem there.

    ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

    To install updates, choose Tools, only download and try to install it manually (it's what they recommend as the fix for the problem of updates, so we should take the word for it).

    Once you've done all the preparatory steps before the downloads, repair. NEt Framework 3.5, uninstall programs, you must uninstall (if you can, or as much as you can according to the instructions) and then reboot the machine to make sure that you leave cool.  After the downloads, but before the installation, turn off all your security software and antivirus software in the case where there is a conflict of something.  Make sure that no other programs are open.  Then follow the steps in the update, then the measures re - install.  Then restart.

    I hope that the two products work now.  I don't think we need to do something for your registry database - weather (it's all these other programs that are the problem).

    If this does not help, then please repost this question in music and its Forum: http://social.answers.microsoft.com/Forums/en-US/vistamedia/threads as well as a link to this topic (so they'll know what's already been tried).  They are the real experts on audio problems and will be more than happy to help you - or you can try the Quicktimes/iTunes Forum where they know the products better.

    When it reboots it just tells me that Windows has stopped unexpectedly.

    First - check that you have the latest drivers for your motherboard chipset, your video device, your audio device and your network devices.  The first place to look for those who are on the Web site for your computer model & specific brand:

    When you select your operating system (Windows 7 64-bit) I see that HP ony supplies those who they provided with the system originally.  It's practically worthless.

    Yes, where to from here?  I would say that you should at least install the latest video card driver - as more modern games can use those strongly...

    Download and install it.  If possible, you still have the original driver installed - this is more recent than most 30 months.

    It's an AMD 785 G chipset card mother configuration, if their site is correct.  Looks like you can download and install latest drivers from AMD for this also:

    I'd say it's a good start.

    What else?  It could very well be a heat problem.  Since it is a desktop - I suggest she get everything, buy some canned air for cleaning electronices and opening of this case and blow off any dust.  It can be quite the accumulation.  After blowing out, make sure that all the components that look like they 'plug' firmly/well connected.  Carefully.  Then, put the cover on and connect.

    Make sure that there is enough air around the case - put a fan in front of him if you have to.
