• How to reset the State of package variables in all sessions connected (without requiring a disconnection and a connect) if they are reset in one of connected sessions.

  
  Hi people,
  Need help, the example requires that the value of packet data 'g_var' must be updated in the session/s connected everywhere without the session/s to be disconnected and reconnected.
  Here's the scenario:

  I created a table my_table having the pair name / value.
  A variable with global package "g_var' in his body and a get accessor method to access g_var variable from the outside world.
  This variable g_var is initialized within the block of the entry into force of the package and retrieves the current value of the variable from my_table.
  When I update the value in the table a trigger on my_table would reset the State of the package and therefore g_var to the most recent value in the same session
  All is well so far since the change in value is reflected in the current session, but if I've already connected session/s
  and I'm trying to retrieve the value of "g_var", it is not updated in already connected sessions and remains the same before the update.
  Can U help please how can I update this value in a session/s connected without having to disconnect and reconnect.
  because if I disconnect and reconect the existing sessions, it seems to show the updated value.

  Thanks in advance.

  Kind regards

  Here are the Scripts:

  end init;

  Start
  init ('$'); -This is a call to time when the package is loaded into the memory of session

  end my_trigger;

  /

  -It is initially set to null
  insert into my_table values ('DOLLAR', 62);
  commit;

  -test value for first time to package loading (62 views)
  Select * from my_table;

  Set serveroutput on

  declare
  my_variable varchar2 (100);
  BEGIN
  my_variable: = my_package.get_g_var;
  dbms_output.put_line ($my_var);
  END;

  -run the same block of end to start in another session it shows 62. All is well so far
  -check if the value after the update in the same session (shows 38), also check in another before the connected session as well (shows 62 and not 38)
  Update my_table set my_variable_value = 38 where my_variable_name = "DOLLAR";
  commit;

  Select * from my_table;

  Set serveroutput on

  -It displays 38 in this session, but there in an already connected session 62 and only after you log out shows 38
  declare
  my_variable varchar2 (100);
  BEGIN
  -my_variable: = my_package.g_var;
  my_variable: = my_package.get_g_var;
  dbms_output.put_line ($my_var);
  END;

  Package variables are stored in the private memory (PGA). The value is not visible in the session. A package variable is therefore not approach appropriate to your problem. You can look at in the context of the Application, as Solomon has said.

• Pls hlp! How to reset the State back to a page...

  I have implemented a multi page doc and have created beween navigation pages via a button at home.

  step 1 click the icon home and step 2 that a wheel appears with a choice of pages to go then.

  Everything works fine the 1st time I go to each page, but the back for the 2nd time that the wheel is always in the center of the page. I want that this reset whenever I go to each page.

  See below link to my example – hope that all makes sense.

  https://www.dropbox.com/s/td6274sm8t74955/test%20wheel_v.indd

  Thank you very much

  Claire

  The first action the button must be going to the State 1. Who clog the DSO as it appears that the first State is empty. Ok.

  For the second action use go to url and use the navto command to access the article/page you need.

• Reset the State of the permissions for the BBM integration tests

  For the purposes of testing, I want to cancel my BBM surveys application registration and clear all permissions for this.

  Now when I remove and redeploy the application, he recorded again but do so without up permissions dialog window to ask if I want to allow it to access BBM or not.

  What should I do to get that back? If I go to the window of permissions of Applications in the settings (which is extremely buggy, incidentally) and disable the authorization of BBM, it does nothing but block the application to use BBM.

  Try to change your application id then. (The in the bar descriptor). That * has * to work, by definition. If it isn't, then you're doing something wrong, I think. If you change the id app, it's actually a different application.

• How to reset the content when switching between tabs

  My use case, is that I have all of the multiple tabs displayed in the sidebar. The content of the tabs each has a title bar of free-form which is scalable. If lets say on tab 1, the title bar is developed, and then when you go to the tab 2, is it possible the collapse of the State of the title bar in tab 1 expanded. Or when you switch to tab 1, is it possible to reset the State of the title bar - meaning collapsed.

  I tried all possible solutions, such as the resetExpanded() or use of the definition of the extended property to false dynamically but no work.

  The only thing working is while I'm in tab 1, I develop the title bar while in the same tab, if I perform any other action, I could run resetExpanded() but that's it. Outside tab 1, as in the QML who has the tabbed pane, listening to side bar changed state events, events to change active tab etc., none to take effect.

  There is no ID for the expandableArea so I couldn't get to the extended property that I could create an Alias for.

  Also the unique ID that gets me access to the resetExpanded() is the ID of the

  FreeFormTitleBarKindProperties, and that's how I'm able to do the

  ID.expandableArea.resetExpanded () BUT that I couldn't create an Alias for this FreeFormTitleBarKindProperties because it is not to be an alias of an identifier is valid.

  So I don't know how to solve this problem, unless there is a way to destroy the contents of the tab whenever I switch to a different tab, but it is very inefficeint and suffers poor performance.

  Any ideas anyone how to solve this problem. Appreciate your help.

  Finally, I was able to solve it!

  Originally I had the game content tab statically at the beginning in the tab "as

  Before:

  Tab {}

  {somePage}

  }

  }

  After:

  Now, I created somePage using ComponentDefinition and assigined the content of the tab as

  tabbedPane.content = somePage, followed by all the properties of customization that I send to somePage

  Now in TabbedPane, I listen to two events below

  onActiveTabChanged: {}

  resetTabContent();

  }

  onSidebarVisualStateChanged: {}

  resetTabContent();

  }

  resetTabContent - calls the function

  function resetTabContent() {}

  mainPane.activeTab.content.resetDropDown ();

  }

  The resetDropDown() function is globally on all aspects for the TabbedPane

  {functionresetAccountsDropDown()}

  contentArea.expandableArea.resetExpanded ();

  }

  where contentArea is the ID of the kindProperties of the title bar

  {Page}

  title bar: title {} bar

  ID: pageTitle

  scrollBehavior: TitleBarScrollBehavior.Sticky

  type: TitleBarKind.FreeForm

  kindProperties: {FreeFormTitleBarKindProperties}

  ID: accountsArea

  {Of container

  }

  {expandableArea}

  }

  }

  }

  }

• Restoring the State of an element of the ADF

  Hi all

  Jdev version: 11.1.1.7.1

  I'm iteration on a nested list and adf creating components at runtime from my bean in scope session based on the user input, now the problem is that I have to reset available to the Group Panel again when the user clicks the button of rest and recreate all children, based on a different user input.

  The layout of the Panel group is not even when using resets:

  or the other

  searchResultPanel = new RichPanelGroupLayout();

  or

  searchResultPanel.restoreState (FacesContext.getCurrentInstance (), null);

  Can someone tell me how can I reset the State of the provision of the Group Panel in my managed bean.

  Hello

  You create the PGL programmatically? If you are only his children to programmatically create, then bind the PGL to a bean, as well as in the valueChangeListener get PGL and then remove all its children, and then add accordingly. Also, be sure to trigger a partial update after adding.

• How to make shift register init happens only once, so that the data can persist across multiple tracks of a loop?

  Here's the situation:

  We are repeatedly followed eight real-world signals and comparing them to a threshold value.  We do this via a loop For inside a While loop.  The loop For runs eight times per pass.  We have implemented a binary table 1 d and the use of the index of the loop For as the array index, by putting a Boolean result in the table using the function replace table subset.  We want to keep the data in the table to be 'sticky', in the sense that any True value is locked, so even if a fake comes later, this array element true.  However, since we initialize the array in order for the replacement to the work table, we see that whenever the loop For again, it resets the table and destroys the history.

  I have attached a simple VI to illustrate the concept, using a random number generator as a stand-in for the real world signals.  How we change this VI do and entered real lock through multiples for loop runs, indefinitely?

  In case it is not obvious, I am a relative beginner, so please keep count in your response.

  Thank you

  For B, although I love the simplicity of it, I have a question: it solves the problem of the re-initialization?  What the shift of the While loop register get initialized - only once during its launch?

  Yep, the shift register Initializes only at the beginning.  You could say that every time the while loop is called (not each iteration) the shift register is reset with the wrong table.

  And, Yes, GOLD will always keep a REAL when it is TRUE.

  Usually, the simplest solution is the best.

• Can you run the Interface of Inspection VBAI only once and then once more by a guest user?

  Can you run the Interface of Inspection VBAI only once and then once more by a guest user?

  I don't think I understand what you are trying to accomplish. You can connect a button on the front of the smart camera and trigger each acquisition. In VBAI check the triggered Acquisition under the tab trigger for the step to acquire Image (smart camera).

  Your smart camera is hooked up to a monitor? Is there something that you must do in LabVIEW that you can't do in VBAI about the step of user input?

• When I use the library function node call in real time, is loaded only once for all or load the DLL whenever it is called?

  When I use the library function node call in real time, is loaded only once for all or load the DLL every time when it is called?

  I have a critical application in real time, in which I use a piece of DLL function developed in C++.  It is ok?  Make sure any senior developer?

  Thank you in advance.

  The user interface thread is the thread that is used to update the user interface. It's slow. And it's supposed to be that way because humans are slow.

  The call library function node can be configured as this thread to use in the configuration for it dialog box. Please visit the LabVIEW documentation on how to do this.

• the event structure cannot combine with other events and run only once

  Why it will always get stuck when I combined the 'new user add' event to the event of 'Login '?

  It works for me when I separate the two, but the 'Add a new user' button can work but only once for the structure above, program will be blocked on the second time that I press the button "add a new user".

  

  It has already been said, you must use that a single structure of the event and not 2. Also, avoid using local variables (better store data in a shift register and not in an indicator) how you do it, it can cause bad racing conditions.

  Actually here you just don't another data storage since you have a file. Don't store data file to the root of the C drive, you do not have write permission. Use the default data folder or the folder of the application.

  I have attached a simple example. I guess that's a work at home? Please make my account help: try to understand why your VI does not work and try to find a solution by yourself. Modify my sample and play with him. This is how you learn LabVIEW. If something is not clear, post here, and we can explain/help.

  Edit: has the 'connection' event, I don't check against whether the file exists or not. Difficulty of this part, gives too little practice.

• While the loop within a box Structure runs only once a target FPGA

  I have a card OR cRIO-9012 RIO for the HIL system. I have a target FPGA file when I use a While loop within a while loop I use the box Structure to check a real condition inside I have the function of activation of the ports and selecting the analog and digital ports. But for my code the code runs only once on repeted times that we have in the LabVIEW environment.

  I also need help to optimize the code. I've seen people using While loop timed in the FPGA target I don't use in both cases.

  I've attached my FPGA with the Version of LV2012 file.

  Waiting for your comments.

  Thank you and best regards,

  Ganesha Moorthy

  You have while loops inside the structure to deal with a constant of false cable to the stop condition. These loops will obviously never stop so browse your outside while loop (containing the case structure) can never.

  This has nothing to do with the FPGA target, the same thing will happen in the development environment.

• Haw to find the element in the table that appears only once

  I have a table like this 2d:

  1 2 3 4 5 0

  5 6 2 4 7 2

  8 3 6 0 9 4

  5 6 7 7 3 2

  And I need to find items that appear only once in this table

  In this case, 8 and 9

  I also need this elements (row and column) position

  Are integers

  I tried to remodel the table and use the find but no result.

  Your best bet is to remodel a table 1 d do your seaching and use 'Quotient & rest' to convert location (index) in the table 1 d back to the index in table 2D. Use "Array Size" to get the number of rows and columns of the table 2D.

  The histogram only works on 1 d arrays.

  Or reshape a 1 d table. For each digit (0-9), use 'Search 1 D Array' twice. If the first 'search' finds a match (does not =-1), use the offset to start the 2nd search beyond the 1st index discovery. If 2nd 'search' returns-1, then one and the SAME time happens

  The index of the first 'search' to calculate the index (Quotient & rest") line and collar of the 2D array.

• Got paper stuck in the printer and now will only print proofs. How to reset the printer

  Got paper stuck in the printer and now will only print proofs. How to reset the printer

  It looks like you may have some saved jobs in your queue that need to be removed.

  Here's how:

  To clear the print queue, stop the print spooler service and delete all the jobs/print pending.
     
  You cannot delete all print jobs in the queue so that the Print Spooler Service is running.
        
  To stop the Print Spooler Service, click Start, run and enter in the box:
         
  services.msc
         
  Click OK to open the Services Applet.
         
  Locate the Print Spooler Service, right click and choose 'Properties' and then click on the "Stop" button to stop the Print Spooler Service is running.
     
  The option "Startup Type" of Service properties print spooler is usually set to "Automatic" (which is now a good time to check it out).
     
  If the "Startup type" is not set to "Automatic", set the "Startup type" to "Automatic" If that is your desire (which now is the time to check it out).

  Do not try to start or restart the Print Spooler Service immediately.  You must remove all print jobs backed up first...
     
  Then, delete all updates pending upward and forward to printing from XP.  If they do not print before, you will need to send the to the printer again.
     
  Using Windows Explorer, navigate to the following folder (assuming that Windows is installed on your C drive):
     
  C:\WINDOWS\system32\spool\PRINTERS
         
  Delete all the print jobs in queue (select and delete all the files) in the folder if the folder is without waiting for print jobs.  The folder must be empty when you are finished.
         
  Reboot your system and check the Print Spooler Service again to make sure the Print Spooler Service restarts automatically restart (given that the startup type is set to automatic).
     
  After the reboot, check again the Spooler Service for printing and the 'Status' column for the print spooler must be read "started."

  Submit new failure of print jobs.
