  After typing this post, I went back to the SDK download page and noticed there is a new SDK available (as dated February 3, 2012) 2.0.0. I used the previous version dated SDK Date January 16, 2012.

  So I advanced and upgraded to the latest version of the SDK, and this error no longer occurs.

  It must have been a bug.

  So I solved (kind of) my problem... Kudos to me... ha!

• Wheel rotation during the passage of the apps

  Hello

  I frequently meet the spinning wheel during the passage of the apps. For example an app can do one, but open window have not been used for a while and then when I click on the window to use it I get the wheel spinning for a few seconds.

  I am running Yosemite 10.10.5 on a MacPro Mid 2010) with 16 GB of ram and 12 GB available on the 300 GB SSD drive. I just realized that maybe space on the boot drive may be the cause, so I'll empty now and update if there is no change.

  Also, my SSD is a 500 GB Samsung SSD 840 EVO media and I think that the TRIM is not enabled? I read that TRIM was not based with SSDS of third party on my machine and was picking up information contradictory as to the time it was a problem or not. The lack of TRIM could be the cause of the spinning wheel?

  Duane

  You ran a 'cleaning', 'optimize' or 'speed up' apps on your Mac?  Have you installed an antivirus software?

  The 12 GB of free space must be sufficient and not to be the cause of the problem. Don't let him get any small however.

  

• Bug found during the use of references to the control in subVis on Compact RIO?

  Hallo,

  I have a simple task. I want to read higher VI into a Subvi the real value of a control to a level. I want to solve this problem by using a reference to the control.

  I have attached a simplified program that shows this.

  But the problem is now. When I run the main VI on a cRIO-device, the indicator "DataByReference" is not updated with the actual value. Only when I opened during execution of the "RefMain.vi" too, then everything works fine.

  More strange thing is, when I run the VI of hand on the host PC, everything works well, also without having to open the "RefMain.vi" when executing.

  Someone at - it an explanation for this behavior?

  Thanks in advance!

  This isn't a bug.  See this explanation.

  Hello

  • What were the changes made before the problem occurred?

  I recommend you perform the clean boot.
   
  Configuration of your system in a clean boot state helps determine if third-party applications or startup items are causing the problem. If so, you need to maybe contact the manufacturer of the program for updates or uninstall and reinstall the program.
   
  See the following article in the Microsoft KB for more information on how to solve a problem by performing a clean boot in Windows Vista or Windows 7:

• HP LaserJet Enterprise 600 m602 slow printing during the passage of the trays

  Hello world!

  On the HP LaserJet Enterprise 600 m602, who met breaks in print jobs during the passage of the trays?  Example, we are going to print invoices and we have a rule configuration that prints on plate 2 with the exception of the last page that is perforated paper tray 3.  So, in a job of 5 pages, pages 1-4 are the tray 2 paper... then page 5 is perforated tray 3.  There is a 2 to 3 seconds when the last page is extracted from tray 3.  If the invoice is only 2 pages, the print job appears super slow.

  This printer was working fine with no delay until we applied the firmware 2302786_433718.  Now, the delay is very noticeable.  We do not know if it was intentional or not in the new firmware.

  We use the latest PCL 5 Universal Print Driver.  The only thing that has changed is the firmware.  We even tried a full reset of firmware.  Problem is still there.

  I worked with HP support, but we were told to wait... the next version of firmware that may or may not fix everything.

  Any help or insight is appreciated.

  We have this same problem with our printer HP Laserjet 600 M602.

  Could solve by setting the Print Mode to all papertypes that are used for the same parameter.  We thought initially can be a problem, issue or firmware of the Board of adjustment, but in reality was the paper type settings. We set up printer for ordinary paper into tray 2 and tray 3, default regular bond has been set at light mode printing and binding for the print mode binding. Each time dial-up printer and trays, he stops to configure different paper type settings.

  Hopefully the other help solve their printing problems

• Reference of the ViewStack/Null object

  Hello

  I'm fighting to develop a solution for the navigation system in my Flex application. I have a ViewStack in my main application file. Every child at the breast ViewStack has it's own ViewStack, and these kids are the real pages.

  I use a Menu bar to change the ViewStack root and child ViewStack:

  private void select(event:MenuEvent):void {}
  If (event.item.@level == "1") {}
  _ROOT. View.selectedIndex = event.item.@index as uint;
  }
  If (event.item.@level == "2") {}
  _ROOT. View.selectedChild = _ROOT[event.item.@parent];
  _Root[event.item.@parent]. View.selectedIndex = event.item.@index;
  }
  If (event.item.@level == "3") {}
  _ROOT. View.selectedChild = _ROOT[event.item.@parent];
  _Root[event.item.@parent]. View.selectedIndex = event.item.@index;
  _Root[event.item.@parent]. View[event.item.@index]. SelectedIndex = event.item.@index;
  }
  }

  The menu items are nested 3 levels deep. I'm always on the second level. I'm caught on the highlighted line, he throws me a Null object reference as the ViewStack Child has not yet been instantiated and therefore cannot be loaded via the menu bar.

  How do I instantiate each child needed via actionscript? If I could add a line before the purple line to instantiate the component then it must not be null when it is referenced in the property 'selectedIndex' I think that would do the job.

  Fine thanks

  Jesse

  Well, you could say all viewstacks to have a policy to 'all '.  This would ensure that the children are all created by avoiding the null pointer exception.  The best idea is to use a framework or a variable bindable that looks like the viewstack index it should be.  For example, I use Mate, so I would inject the variable stackIndex of a class of presentation.

  ...

  [Bindable] public var stackIndex:int;

  This way is better because it allows deferred instantiation, reducing the startup time and shows the separation of concerns

• Reference Dell backup and restore - "an error occurred during the creation of the backup of the system"

  I have a Dell XPS-8700 running Windows 7.  I bought the Dell Backup and Recovery Premium Edition.

  I was able to create a backup bootable (hot spare), and I can create a backup of data on my external hard drive.  However, whenever I try to create a backup on my external hard drive system, after about three seconds in the process, he returned: "an error occurred during the creation of the backup of the system.

  How can I create a backup of the system?  Why I get this error?

  Thanks for all the info. My situation sounds very similar to yours.

  I removed using Add/REMOVE programs in the control panel DBR and he removed cleanly.

  V1.7.1.2 downloaded and executed new facility.

  When I ran, it was my premium license key so he had yet to register and was not removed by uninstall.

  As before, Rescue Disk ran and installed the new partition (DBR_BOOT) on WD Passport.

  However, backup system immediately stopped with disconnected, missing target location or full. Tried several times...

  In any case, sounds like you have solved your problem, so you like OP should this brand this post/thread as answered. I will continue to post on my other thread.

• ORA-25401 cannot continue error extraction during the 2nd test of passage for the customer

  Hi, I finally pulled out straight and everything works fine.
  
  Purpose of test, I ran a very long query in the form: select * from user.longtable and in the Middle I made a switch to the hysdev. The session stops seconds and then switch to the query. I also tested by smon kill remedev in the middle of the query, and the sesion will be able to pause and continue.
  
  But after the 1st pass and I did another pass back to hydev, it will be given an error: ora-25401 cannot continue extraction error.
  
  How to solve this problem?
  
  I tested the failover and during the query, I killed smon on primary, he'll give me the same error.
  
  Can someone tell me how to solve this problem? Or the world has experienced before?
  
  Thank you

  The Java Exception: java.lang.reflect.InvocationTargetException: during the java.lang.reflect.Method .invoke call.

  I came across the same thing as you. I did a lot of experimenting and found it works:

  var result = (function() {
      var ReflectiveArray = java.lang.reflect.Array;
      var CreateSQL = Packages.PeopleSoft.PeopleCode.Func.CreateSQL;
      var columns = ReflectiveArray.newInstance(java.lang.Object, 1 /* number of selected columns */);
      var results = [];
  
      SQL = CreateSQL("SELECT OPRDEFNDESC FROM PSOPRDEFN WHERE ROWNUM < 10");
      while (SQL.Fetch(columns)) {
          results.push(columns[0]);
      }
  
      return results.join();
  
  }());
  

  He seems to have been a problem with translation between the JavaScript array and the Java array Object []. I solved this by using java.lang.reflect.Array.newInstance to create a new instance of the object [1].

  Next issue to deal with is your memory problem. In the error message, it seems to have something to do with the Garbage Collection and a lot of temporary objects. You declare you line and cell by using the var =... line and cell var =...? If not, then they are in the global namespace and properties of the global object. At the end of each iteration of the loop, use delete line and delete cells. If you declare the var, then set their value null at the end of each iteration. Based on your code, I expect each time through the loop would decrease the number of references, but I saw where setting explicitly using null. The only other temporary object I see is the value in the table. Just for fun, I added this at the end of each loop, and he ran very well:

  columns[0] = null;
  

• Screen / phone does not not during the current incoming call.

  All;

  I just noticed this behavior 2 days ago and it went this AM as well. During an incoming call, I tried to access the data on my Bravo but the screen was dark and pressing the unlock/lock button at the top has nothing more than any other control. I haven't lost the appeal and I got the info written down, so I got to the question on the ground. As soon as the call is completed, I could see the screen by pressing the menu and then command unlock the phone with the swipe.

  I also noticed that there are no e-mail messages. I decided to power off the device (soft reset). Messages, then went down, but 2 days ago I did not have a message problem. But had the black screen and no access to the phone during the call. I've not seen this with outgoing calls. I have no trouble to access items on the phone call I have orginate. All the world has noticed this incoming call blocking? It would almost seem that controls spend sleep during incoming calls. I have not found references in this regard so far.

  I found that when the phone is turned off and then back on most of the problems are solved. Since I'm old to computers in general this is not a surprise but falls into the area of practice or standard procedure. I will say that the absence of data loss during these resets is a good thing.

• Other results: preliminary report does not properly during the first run in a loop

  I have an unusual problem with NI TestStand 4.1. I have a loop For and it contains, I have a call from sequence configured as a test of numerical limit. This test is configured to report additional results. All other results are preconditioned test cases. Here's the unusual part: during the first iteration of the loop, the test passes yet additional results for the parameters of all inputs are reported (output parameters are not presented at the time, but more on this later). Spend all additional this test iterations in the loop For and additional results are not reported.

  Regarding output parameters... If a test fails I'm expecting (input and output parameters) results to report. However when I encounter a failure only the additional results that are output parameters are displayed on the test report. Input parameters are not reported.

  If anyone else has experienced this? My expectation was that all additional results would be declared in case of failure. In addition, in the absence of a failure I expect not to see additional results. Thanks in advance!

  The short answer is that the condition of additional results for input is evaluated before it's called the subsequence, so that it uses the value of the previous iteration Step.Result.Numeric (or by default on the first).

  You can see this described as stage 15 in the following link:

• during the construction file name collision

  LabVIEW 2011.

  I have a build specification where I copy a file in the target directory.  The name of the folder is "always included."

  The folder contains the subfolders and the subfolders of the data files.  The data files in subfolders all carry the same name, if for example we

  High back (always included)

  Subfolders one, two, three

  and in each subfolder, we have a data file named Data

  When I build I get the following message: "Labview has prevented a file name collision during the build. Names of duplicate files can be copied to the same destination... "and it references the three data files named Data.

  Well, that's all just crazy.  They are NOT copied to the same destination.  Generation does not understand a simple tree structure?
