debugging object references

• Message = "Object reference not set to an instance of an object."

  I was running my site Visual studio in mode on the local computer and everything worked very well. I added something to your cart, then it looked as if we'd send her to the last step before you check out through paypal and I closed it. That must have caused a problem because after that, when I tried to open another page, I get this message:

  System.NullReferenceException was unhandled by user code
  Message = "Object reference not set to an instance of an object."
  Source = "App_Web_iy6hza-b".

  InnerException:

  And when I've debugged, it stopped in the code of the controls/ShoppingCartBox.ascx and gives to this line in yellow:

  And debugging box States: NullReferenceException was unhandled by user code.

  Object reference is not set to an instance of the object.

  It gives then a few suggestions like the use of 'new' somewhere but I don't know where I would put that or if it would help.

• ActionScript3 Error #1009: Cannot access a property or method of a null object reference

  Having a problem with the creation of a website in CC animate with ActionScript3.

  Any help would be appreciated.

  Basically, I'm trying to get 'home', 'services' 'contact' buttons work when you click "about".

  import flash.events.MouseEvent;

  Stop();

  header_mc.home_btn.addEventListener (MouseEvent.CLICK, gohome);

  gohome function (event: MouseEvent): void {}

  gotoAndStop (1);

  }

  gotoAndStop (3);

  }

  header_mc.contact_btn.addEventListener (MouseEvent.CLICK, gocontact);

  function gocontact (event: MouseEvent): void {}

• Help, please! TypeError: Error #1009: cannot access a property or method of a null object reference.  Help, please!

  Can anyone help! Here's the code from to escape the game of the room that I am creating.  Basically the user will be drag and drop items to reveal the user will collect hidden items.  I got the elements of drag-and - drop but I have a problem with the service that I write to recognize what are the elements and how much has been collected.  I just get the error

  TypeError: Error #1009: cannot access a property or method of a null object reference.

  at TheMathsRooms_fla::MainTimeline/ObjectFound()

  When I click on one of the elements, the user must be able to collect.  I checked the chronology and pint, the script is used all THE elements are on the scene.  Any ideas?

  function objectFound

  function ObjectFound(event:MouseEvent):void {}

  var room1_inventoryName:String = "room1_inventory" + event.target.name;

  var room1_inventoryItem:DisplayObject = getChildByName (room1_inventoryName);

  Event.Target.alpha is room1_inventoryItem.alpha = 100;.

  founditems ++;

  Event.Target.alpha = 0

  }

  Here I put the items in stock to be invisible until they are

  room1_inventoryone_mc.Alpha = 0

  room1_inventorytwo_mc.Alpha = 0

  room1_inventorythree_mc.Alpha = 0

  room1_inventoryfour_mc.Alpha = 0

  room1_inventoryfive_mc.Alpha = 0

  room1_inventorysix_mc.Alpha = 0

  A variable is created to count the number of items the player has found.  At the beginning of the game, it is set to 0

  var founditems:Number = 0;

  Here, I'm telling Flash to keep track of what the user has found by listening to what were clicked on and then by running the objectFound function.

  room1_hiddenone_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

  room1_hiddentwo_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

  room1_hiddenthree_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

  room1_hiddenfour_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

  room1_hiddenfive_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

  room1_hiddensix_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

  Here's the function to allow the items to drag and drop

  function StartDragging (e:MouseEvent) {}

  e.currentTarget.startDrag ();

  }

  function StopDragging (e:MouseEvent) {}

  e.currentTarget.stopDrag ();

  }

  This shows that items can now be dragged and lowered some will reveal hidden items

  Bluechair.buttonMode = true;

  Bluechair.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

  Bluechair.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

  Pencilcase.buttonMode = true;

  Pencilcase.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

  Pencilcase.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

  Painting.buttonMode = true;

  Painting.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

  Painting.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

  Rubbish.buttonMode = true;

  Rubbish.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

  Rubbish.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

  Painting2.buttonMode = true;

  Painting2.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

  Painting2.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

  Trunk.buttonMode = true;

  Trunk.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

  Trunk.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

  Pillow.buttonMode = true;

  Pillow.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

  Pillow.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

  Click file > publishing settings > swf and check the box "enable debugging".  test.

  the number of problematic line will be in the error message that allows you to quickly identify the problematic reference which is probably room1_inventoryItem.  use the function trace to confirm:

  function ObjectFound(event:MouseEvent):void {}

  var room1_inventoryName:String = "room1_inventory" + event.target.name;

  trace (room1_inventoryName);

• "Object reference not set to an instance of an object." on track

  Dear members,

  Today, I tried to "build and Run...". ' a rule base that I created some time ago and executed correctly. Now, I get the error "Object Reference." not set to an instance of an object When I try to run the basis of rules using Oracle Web determinations (construction is always successful). When I run the basis of rules by using "build and debug...". "no errors are presented and the basis of the rule is executed successfully as well. I can also access the basic rule in my web browser without having any problems. I expect that the cause of the problems lies in the recent installation of Google Chrome or Mozilla Firefox, but I don't know where to look for a solution. I already tried to install the latest version of the Oracle Policy Modeling, but the error has not been resolved by then.

  Dear Frank,

  Thanks for putting me in this direction. I never looked in the browser by default settings, because they never changed. In other words, Microsoft Internet Explorer is and has always been my default browser. Do even Mozilla FireFox or Google Chrome my default browser solved the problem (partially). Since we are analysts we of course want to know how the problem occurred. In addition, because the problem is not completely solved yet, it seems to be some sort of bug left in the Oracle strategy modeling.

  • I used the modeling of the Oracle strategy for six months without having any problems. The basis of rules was always run correctly in Microsoft Internet Explorer (which has been configured as the default browser).
  • I installed Google Chrome and Mozilla FireFox at the same time, but has not changed my default browser settings (so Microsoft Internet Explorer is the default browser).
  • Run a basic rule of now caused the "object reference is not set to an instance of an object." even if the default browser has been set successfully.
  • I changed the default browser to Google Chrome or Mozilla FireFox (which of the two is not serious) and rules was performed correctly in the specific browser.
  • I changed the default browser to Microsoft Internet Explorer, but the Oracle strategy modeling keeps using my default browser defined previously (Google Chrome or Mozilla FireFox).

  From there, I guess we can conclude that the Oracle Policy modeling does not resemble the right registry key to determine the default browser. In other words, Oracle Policy modeling is unable to identify Microsoft Internet Explorer as the default browser, where other applications (like Google Chrome and Mozilla FireFox) do this properly. I expect that the HKEY_CURRENT_USER\Software\Classes\http key is sought (which did not exist after I installed Google Chrome and Mozilla FireFox), but for the Windows operating system this key is only used until Windows XP. Windows Vista from the HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice key should be used to find the default browser settings.

  This isn't a problem of Flash... it's a mistake to designer.

  1009 error indicates that one of the objects targeted by your code are out of reach.  This may mean that the object...

  -is declared but not instantiated

  n ' is not have an instance name (or the name of the instance is misspelled)

  n ' is not in the frame where this code tries to talk to her

  -is animated in place, but is not assigned the name of the instances of each keyframe for her

  -is one of the two or more consecutive keyframes of the same objects without a name assigned in the image previous (s).

  It could also be other less obvious reasons.

  If you go to your section to publish the Flash settings and select permit debugging option, your error message should have a suite of line number the number of the frame that will help you to isolate the object that is involved.

• Error 1009: Cannot access a property/method of a null object reference

  OK, so I've spent the last few weeks trying to figure this on my own, looking at the other tutorials and nothing has helped my situation. I am beyond frustrated with this project and I just want to find an answer quickly. I have some experience with Flash to school, but I can't understand this because it doesn't make sense to me.

  I have two main parts of my file. I have a photo gallery and I have a video. The home page allows the user to take them to a number of areas where they can see a gallery of photos or video from a certain city. Photo gallery works fine as do videos. Well, now, user can get the gallery photo to video, but when I try to set up exactly the same thing to bring video to the images it gives me an error of output message:

  TypeError: Error #1009: cannot access a property or method of a null object reference.

  function showBrowntonPhotos (e: Event): void {}

                          gotoAndStop (1);

  }

  All this code is not on the main timeline, but in a movie clip called mc_brownton where I have the pictures and video all on the same timeline.

• Property or method of a null object reference. "OK, go crazy. account of $ 50 for a paypal account, if someone explains why &amp; solution - "cannot access a pro."

  I guess that's cheezy to offer money to help (and I guess this a little tied to a post being discussed yesterday), but I'm so tired of searching - been trying things ALL day and its value at a minimum of $ 50 if someone takes a while to help with an explanation of what is happening and how to fix it (hopefully it's just a matter of newbie that I) be cursing myself for lack.)

  If you file a bug with your testcase, this will help to make sure we don't break it in Flex 4.  I don't know if there will be a new version 3.x.

  I got around the problem by adding to the level superior canvas in Main.mxml:

  defaultButton = "{mainNavigation.addEmployeeButton}" "

  In my view, that principle is once you assign a default button in a container, to keep something like the default button after that.  If the focus moves to a container without a default button, then I think he's in trouble.

• Access to the elements of an array passed as object reference

  Hi all!

  I am quite new to TestStand and therefore, my question might be simple enough but I was not able to find the solution by looking at previous posts.

  I have a sequence that passes a custom array (of data type) to another to make basic on the table stuff (reverse the order of the elements, for example).

  I want to move to the sequence called an object table reference

  The problem is that I am not able to read the array element inside the sequence called using the object reference.

  I found the way get the number of items, but I'm not able to access the item

  In addition, the TestStand GUI is able to let me see the array pointed to by the object reference that is passed within the known sequence, so it is possible to access... but how?

  I want to do operations on the object reference passed within a 'No return' TestStand if possible.

  Thank you very much.

  Andrea

  In other words:

  How do I access the field 'temperatureTag' item number '0' from the object variable reference referenceToClone?

  Locals.referenceToClone [0] .temperatureTag does not work...

  

  I don't know what is the recommended method to solve your problem. When you try to few alternatives, I was able to get the value required by the following expression (tested with TestStand 2014):

  Locals.referenceToClone.GetPropertyObject("[0]",_0).temperatureTag

  Try and tell me if it works for you.

  Use this workaround with caution.

• find the memory leak when switching from Teststand object reference to vi

  I use Teststand to call labview vi and col ThisContext sequence to vi as object reference, but if I just completed this step and I can find the memory to help keep more, how can I avoid leaks memory inside the vi.

  See my vi, is displaying an interface message user.

  

  You should use a node reference close to close the references that you get after an invoke. In the code below, you should be able to close the references that you get the following:

  AsPropertyObject

  Thread

  Close these two references, once you're done with them.

  Also make sure you have turned off the collection of results of your sequence or you will use memory constantly to the results of the stage.

  Hope this helps,

• the station's overall object references

  Are station global object references stored in a file as the globals other station? If so, how?

  The values of the attributes of the object can be recovered?

  Reference values are not preserved in the files. It is not technically possible in the general case, since a reference can point to any ActiveX object or .net.
