• the bellows code try/catch/finally block will be executed in the case of exception? REFdn6025108709

  Hello guys

  I have a question about the AS3.0 and the try/catch/finally block. When an exception thrown an exception in a try block, will be the runtimer continue to run the following code to the try/catch/finally block?

  For example, assume that the tracking code:

  public void attackEnemy (enemy: SpaceShip): void {}

    try {}

  setCurrentTarget (enemy);

  fireOnCurrentTarget ();

  { } {finally

  setCurrentTarget (null);

    }

  trace ("attach completed");

  }

  The appeal of "trace" will be executed is the one exception?

  If Yes, what is the point of finally block?

  Kind regards

  Dennis

  In your example you have no catch block, then if an error is thrown in

  your try, the trace statement block will never run. The finally block

  will run even if an error occurs or if there is a return statement in

  your try block. Finally block is useful to ensure that a cleanup code

  is executed regardless of how a function left.

• problem with thread and try {} - catch () {}

  Hello

  My problem is that in the second thread of my request, there is a method (at the beginning) that connects with the server. If the connection is impossible-i try to reconnect two times. the problem is that the connection must by in a try-catch block. and when I can't connect for the first time, the program will the something something trying to reconnect. and the problem is that once my progam enters this something, the thread is dead!

  Do you have any suggestions, what can I do with it?

  concerning

  I reorganized my request. whenever I see that the thread is killed (with an exception of capture) I wait 2 seconds and start the thread. and it works like a "reconnect".

  Thank you for your time and suggestions!

• ExtendScript try/catch difference when the script took the ESTK and Illustrator

  Hello

  I wrote an ExtendScript for Illustrator using the toolbox toolbox ExtendScript (ESTK).  It works fine when running scripts it in Illustrator from the ESTK (using the target application functionality).

  However when I run it directly in Illustrator (by selecting it in the drop-down file menu > Scripts) I get a runtime error.  Is this normal?  Should I expect differences when you run the script in these two different ways?

  The error is in this feature...

  ```

  function itemUsable (arr, item) {}

  use var = true;

  try {}

  arr [point];

  usable = true;

  } catch (e) {}

  $.global.alert (e);

  usable = false;

  }

  usable back;

  }

  ```

  The code point is around the issue of the Illustrator to throw errors when accessing properties that do not always exist.  Connected ESTK the try/catch statement intercepts the error "No such item" and then sets the function returns false.

  When ran directly in Illustrator, the lights error message but the try/catch does not seem to stop the output script.

  The only difference I see is when to run the script in ESTK the dropdown next to the application target dropdown is always (and has only the option) 'main '.  Run the script directly in Illustrator, when the error is thrown this menu option drop-down is set to the 'transient' value.

  See this screenshot for an example of what I mean

  

  Any help would be appreciated.

  Thank you

  / t

  Try adding $niveau = 0 at the beginning of the script or consult the last entry on the debugging of the ESTK tab

• Why is my try/catch and onError() not to manage invalid CFML build errors?

  I played around with different ways to place cookies and in the process, I use the wrong cfcookie tag. He threw an error and the onError() has somehow made his work. Rather than giving a nice cleaning as usual error, the page completely stop treatment.

  So I played a little more and tried this with a onError() in the application.cfc.

  < cftry >

  < cfset asdf = / >

  < cfcatch type = "any" >

  < cfdump var = "#cfcatch #" >

  < / cfcatch >

  < / cftry >

  He threw the error, as if the try/catch wasn't there. Is this normal and it took me years to see?

  Phil

  The behavior you observe is expected and correct. Try/catch and onError is intended to catch any exceptions.

  ColdFusion compiles the executable code pages before their execution. Strictly speaking, the exceptions are errors that occur when ColdFusion runs already compiled CFML (CFM and CFC) pages.

  However, what happens when Coldfusion is errors, for example, emissions and syntax when compiling errors? These errors occur before that ColdFusion converts executable code. Therefore impossible to use try/catch or onError to handle them.

  ColdFusion will report errors that it finds during compilation and compiler errors.  This is what is happening in your example. The line

  contains a programming error and therefore won't even compile. That's why you get a compiler error.

  If replace you it with the line.

  you will get a code that compiles, but which generates an exception.

• I tried to open a bookmark and its opening in an active window, such as an image, not a separate tab or window. What is going on?

  I had problems with Firefox hanging (seems related to Flash on a particular Web site). During his last hours of troubleshooting, including on the phone with the assistance of my ISP, it was recommended I "Refresh" of Firefox. I've done it before, and I did it yesterday again. This morning I opened Firefox to my homepage (my ISP Portal), checked my email, disconnected from the email, this tab closed, open two other forums and Photobucket - three tabs open in the window - to post pictures and contribute to the discussions in the forums. Once completed, I've disconnected from forums and Photobucket, each firm separately tab, and then quit Firefox. (While in Photobucket, Flash has crashed several times... but this is not unusual with Photobucket in my experience. It's a different problem, I always deal with... but he immediately forgets...) As part of "Refresh" yesterday, I set Firefox to clear the cache and cookies and other files to quit.

  Later in the day today, I opened Firefox, portal of my ISP opened as usual and expected (my "Home page"). Sometimes, instead of close the window/tab, I just open a bookmark and it will open in the same window, but by replacing the previous window and its contents. I.e. the procedure normal functioning for me. You know, rather than having two windows open where I have to close one, I have just the bookmark opens instead of the original content of the window.

  Today (and it happened before today, but rarely), open the bookmark page as if it was a picture in the active window... otherwise said, my ISP Portal occupies about 3/4 of the window, but more on the left side of the window (not another tab or a window, but in the same window) is a thin view bookmark page. This new web page - quite foreign to the original page - has a scroll down bar, but can be made to fill the window... the previously opened web page acts as a barrier to the pleasure of the 'new' image/web page. While I can understand the right border of the "new framework" and drag it to the right, he still cannot push the 'old' web page of origin of the road... the old page reached a minimum limit and I get a split screen of two completely different websites mode contained in exactly the same active window.

  The 'new' frame has an 'x' at the top right, so I could close... but my question is, why it is opened in web page/window...how from a completely different company can two web pages from completely different organizations/companies/websites are the same active window in Firefox? I have... attached screenshots. And, oh yes, not to mention that the HOW and WHY, how can you prevent (or is the best thing to just right click and open in a new tab or window...?) Which is not always convince me... I am someone who needs to know WHY something happened that should not have happened. It drives me crazy when something strange happens and the 'solution' is to change MY behavior. (You know, like if YOU were the problem, but I need to change MY behavior Instead of correct what's wrong with YOU... When YOU could make all of the obsolete situation.)

  Thanks for everything you can suss out...

  Rwillet,

  Thank you for visiting the Microsoft answers community.

  The wmiprvse.exe file is otherwise known as Windows Management Instrumentation.

  In research, I found a few articles that might help you:

  Wmiprvse - wmiprvse.exe

  You can run your scan virus and if necessary, perform a System Restore to a point prior to the error occurring.

• I try to install Google Earth and its failure and I get an error message: 0 x 80070002, how can I fix?

  I try to install Google Earth on my Windows Vista Edition home premium and its failure and I get an error message: 0 x 80070002, how can I fix?

  The error message indicates "file not found" - which often means a bad download.

  Try another download of Google Earth - if the operation fails with the error message, then...

  There are a few things you can try to solve this problem: -.

  type in the search box
  CMD. EXE
  Right-click on the single file that is
  Select run as administrator
  -the elevated command prompt window should appear
  At the command prompt, type
  CHKDSK C: /R
  and press the Enter key
  We'll tell you that the drive is locked and the CHKDSK runs the next time he started - press Y and restart. The chkdsk command will take a few hours depending on the size of the disk, so be patient!

  Once executed, the command CHKDSK Windows should start normally (possibly after a second auto) - then run the SFC

  SFC - SFC System - Instructions
  Click the Start button
  type in the search box
  CMD. EXE
  Right-click on the single file that is
  Select run as administrator
  -the elevated command prompt window should appear
  At the command prompt, type

  SFC/SCANNOW

  and press the Enter key
  Wait for that analysis at the end - make a note of any error messages - and then restart.

  Try installation again
