• MEV using the context of the Application

  I need to set up an EVP by using a context of Appplication but I still have problems despite the use of the Oracle's Web site examples.
  That's what I'm doing:
  
  I have 2 tables in the schema of the system. One of them is a table of customers and the other is the supervisors table.
  When a supervisor connects, he should be able to read each row in the customer table, which is attributed to him.
  The supervisors table has essentially superv_id and client_id;
  
  So, I have a package that retrieves the ID of the supervisor during his connection. But I have'nt not been able to implement a work
  Function VPD with the application context.
  
  Any help would be greatly appreciated.

  Thank you both for your responses. but I have another question:
  You can use a query nested as a predicate in the DPV service?

  Of course; what you can use in a WHERE clause that you type yourself can also be used in the predicate. A good way to do it in a regular query would be:

  WHERE   client_id  IN  (
                       SELECT  client_id
                    FROM        clients
                    WHERE   superv_id     = SYS_CONTEXT ('MYCONTEXT', 'sup_id')
                   )
  

  so, according to the policy, you can say something like:

  stpredicate := Q'{client_id  IN  (
                                       SELECT  client_id
                           FROM    clients
                           WHERE   superv_id     = SYS_CONTEXT ('MYCONTEXT', 'sup_id')
                                 )}';
  

  Note that you don't need NVL in this case. If SYS_CONTEXT returns NULL, then the IN-sup-query will return no rows, the predicate will be FALSE, but no error is raised.

• the APEX api call, change the repository, in the context of the application has no effect

  Hello

  I call APEX api stored procedures manipulate the repository (such as apex_lang.update_translated_string, apex_lang.publish_application or apex_instance_admin.set_parameter) pl/sql by setting apex_util.set_security_group_id (< workspace_id >) following this example indicated in the documentation of the api of the APEX:

  Start

  --

  -If running SQL * Plus, there set the environment

  -for the workspace Application Express associated with this schema. The

  -call to apex_util.set_security_group_id is not required if

  -you are running as part of the Application Builder

  - or an Application Express application.

  --

  C1 in (select workspace_id from apex_workspaces)

  loop

  apex_util.set_security_group_id (C1.workspace_id);

  "exit";

  end loop;

  -Now, actually create the mapping of the language

  apex_lang.update_translated_string (p_id = 123456789 >)

  , p_language = > 'nl '.

  p_string = > "says is a test");
  

  commit;

  end;

  /

  Call it the SQL guest (or Toad) everything works fine.

  But when trying to call apex_lang.update_translated_string from an application (with or without the security_group_id) APEX, nothing happens. No error message, the process is complete, but the string in the filing of the translation has not changed. Same effect for other api call that I mentioned. I tried the different authentication scheme in my application: DB account, users of the APEX, custom.

  An idea or a clue on what I'm missing here?

  Kind regards

  Christian

  Dear Mr. Rokitta,

  I tested myself on apex.oracle.com just now, and I had no problem using your anonymous PL/SQL block to update the chain of my filing of translation.  It worked successfully to these two SQL commands in SQL Workshop and also inside an APEX application running.  I also looked at the underlying code, and it's so simple - also long the security_group_id is set correctly, the specified ID is valid and the language code is the code of language of the APEX_APPLICATION_TRANS_REPOS chain, the update should go ahead.

  If set you a test on apex.oracle.com case where this would have been does not work, I would be happy to take a look.

  Merry Christmas.

• Panel action and Code Panel cannot be considered in the context of the application

  Is there a reason why I can't open the Panel shares the timeline when I rooted and open code in the application Panel?  If I close the Panel code I can display the Panel shares.  Why can I not have the open two?

  HI, ea2th-

  It was a decision of design from us.  Note that if you click on something in the assets Panel with panel open code, it must navigate to the first manifestation of this element.

• Device from the Application context context

  I am a beginner to programming of Blackberry and I'm trying to understand the different between developing countries in the device against the Application context.

  My development so far has just been messing around with the listeners and figureing on their functioning on the eclipse Simulator

  My current test project consists of a phonelistener that simply writes to console when a phonelistener event is fired. I think that my project as a module system, where this is not really an app its just something that I want, running in the background. But perhapse I think about evil.

  I have my project to "autorun". Now, what are the benefits to my project to extend the Application?

  at the moment I just:

   CustomPhoneListener extends AbstractPhoneListener
  

  It works fine and I can see the console outputs when I simulate phone calls. I know that my sample program is very simple, but can someone shed some light on what problems might come with not extending "application"?

  Thank you

  Stephanie

  Device vs. request context has no meaning for me.

  Each Application has its own context, says Simon if you use a listener usually perform you in the streamed Application context too.

  Re the difference between

  CustomPhoneListeners extends the Application Implements PhoneListener
  and

  CustomPhoneListeners implements PhoneListener
  I would ask you to think about this:

  CustomPhoneListeners extends String Implements PhoneListener

  What is the advantage of the extension of string?  Not really, except in certain circumstances, you need to treat your CustomPhoneListeners as a string!  Same thing with Application, if you want to treat like your own Application, then you might want to code

  CustomPhoneListeners extends the Application Implements PhoneListener
  Personally, I think that you don't want to have an Application also act as a PhoneListener, this does not seem a useful merger.

  About the benefits of creating an Application, it has no value extending the Application If you can work in the listener.  But you can do a treatment long, or perhaps a network call.  Or maybe you are not sure of the reliability of your code.  If you run this in the context of the phone, then if he dies or hangs, it is the phone that is killed.  Not good.  Then you can consider extending the Application, it is started (enterEvent Dispatcher), and then you can pass things for her to run.

  Personally, I do as little as possible in the headphones.

• Problem with the definition of the Application context Variable

  Hi all
  
  In our application, we use political VPD. We use the app context variables to store session level settings. When I'm trying to set the value of context separately through SQL PLUS he started after the exception.
  
  ORA-01031: insufficient privileges

  But the same works very well a procedure. When I am executing the procedure it works fine.
  
  Can anyone of you pls help me?

  I assume that you have created the context related to the packaging?

  Create context SOME_CONTEXT using SOME_PACKAGE;
  

  When you do this, the ONLY place you can set the values of context is the specified package. If you cannot change it directly, you must call the package (whatever the process change it and is available).

  This is a safety mechanism, so you can't do whatever it is that you're probably trying to do :)

• Duplicate the application in the "open with" context menu

  Hi all

  On my iMac, the last OS X El Capitan.

  For an example, so I mediainfo application on the app store and it works fine, no problem.

  What happens if I go to a video rile, do a right-click, open with... There mediainfo twice, optionally including a version and the other a newer version if instead of upgrading to the new version of its kept the two versions?

  So I look under 'Applications' and that is only once not twice.

  I click and hold the icon for mediainfo in launchpad, it wiggles, I press x to delete it form party launchpad and its applications in the finder.

  But there must be somewhere because he is always right click on the menu 'Open with' and it actually load the program if you choose somehow even if it isn't the disk hard mac! ?.

  I did a search and don't see you mediainfo application anywhere on the disc hard mac.

  I have a copy of super duper of my HDD on an external hard drive that probably the application it but can it really be getting the external application and adding it to "open with" menu and launch the application from the external hard drive? If yes then this is not cool...

  I also noticed right on a PDF right-click, open with Watch 2 entrances of Safari 2 on iBooks, google chrome 2, all are an old version and one is a more recent version, where could he be getting from and the addition in the menu "open with?"

  If it is picking up my applications folder on the external drive backup and using that in the open with menu and launch the application from the external backup then it is really bad, it should only be launched from applications to disk hard mac shouldn't it?

  Any ideas?

• How to check that my application is in the context of the background thread

• change the default location of the application

  I installed an SSD and put my system on it. I don't want not used for applications or documents. How can I change the default values of systems use applications and the doc in my HARD disk drive?

  If you move the Applications folder on the SSD, then this means that your applications load more slowly. Leave it where it is.

  How to use an SSD with your HARD drive If you want to use an SSD as boot with your existing HARD disk drive, as the disk 'data', here is what you can do. After installing the SSD, you need to partition and format the SSD using disc utility disc. Then install OS X on the SSD. Once installed OSX boot from SSD. Startup disk preferences to set up the SSD as the boot volume. Open the preferences users and groups. Click the lock and authenticate you. Or CTRL - RIGHT click on your username account list in the sidebar and select Advanced Options in the context menu. You will see a field called "Home dir: ' on the far right, you will see an Edit button. Click on it. In the file dialog box, navigate to the location in house now located on the HARD disk (disk HARD/users/user_name /.) Select the folder, click the Open button. Restart the computer, as shown. When the computer starts, it will now use the home located on the HARD drive folder. Another more technical method involving the Terminal and the alias is discussed in depth here: using OS X with a SSD and HDD - Matt Gemmell configuration. It's my preferred approach because I can choose which records of the House, I want to on the HARD drive and I don't want to. For example, I like to keep Documents and library files on the SSD because I frequently access their content. Make sure that you keep the bootable system entirely on your HARD drive where you need it.

• List of open and active/Windows Forms displayed within Windows XP 7 v/s windows on the right by clicking on the name of the application in the status bar

  Salvation OR,.

  We found that the list of forms/open windows displayed in Windows XP (on the right by clicking on the name of the application in the windows taskbar) seems to indicate all open and active windows/forms in the application.

  We would like to know how to enable the same functionality in a Windows 7 environment. The best we can do now is to double click on the name of the application on the windows taskbar to switch between active windows/Forms in the application. We would like a menu similar to the windows XP appearance about running on Windows 7 when it comes to this particular feature.

  Thank you and best regards,

  -Ashish

  The taskbard has changed significantly in Windows Vista and 7. You can get a similar functionality to what you call by customizing the taskbar in the taskbar properties. In addition, now press SHIFT key while right-clicking to display a menu similar to what you show in your screenshot, except that it does not display the name of the element. In Windows 7, the feature make you is typically done by hovering over the icon in the bar tasks and selecting one of the points of view which appears above the element.

  You can use the Windows shellapi to do a limited customization of the task bar, but this API is very difficult to use and I would not recommend this approach.

  CVI provides a method to change the name of the item in the taskbar (see this KB), but it does not add the name after the restoration in the context menu.

• programmatically change the fonts in the application

  Is it possible to change the fonts of the Application/System-dialog box programmatically? (The method of the UI is: Tools > Options > environment > fonts.)

  I'm interested in doing this in the context of internationalization of an application: for English, Spanish, French, German, I can use, for example, Verdana. But once I have in Chinese that I will meet the problem of having to set the font dynamically. Write code to set the font for each UI element user individually is unmanageable, so I wonder if there is a way to define the fonts in the Application, system, and dialogue.

  Thank you

• Call any thread DLLs the application crashes

  I have a built in 2015-labview application that acquires spectra of 6 spectrometers via an external dll. The dll triggers an event in labview when data is ready to be pulled from the spectrometers. Since this event, I am running a reentry no void / vi which contains a node function to retrieve the data, that are configured to run in any thread, as it gives a drastic improvement of performance as apposed to run in the UI thread.

  However this can slow down the application crash with a message from windows like the following journal:

  Name of the failing application: axiom 2.0.exe, version: 1.0.0.82, time stamp: 0x5581a6b7
  The failed module name: lvrt.dll, version: 15.0.0.4024, time stamp: 0x5581ac03
  Exception code: 0xc0000005
  Offset: 0x0000000000bec7c0
  ID of the process failed: 0x15c0
  Start time of application vulnerabilities: 0x01d11e6face9febd
  The failing application path: C:\Axiom 2.0\builds\Axiom 2.0\Axiom 2.0.exe
  Path of the failing module: C:\Program NIUninstaller Instruments\Shared\LabVIEW Run-Time\2015\lvrt.dll
  Report ID: 7d4ef3a8-8a91-11e5-94e9-90b11c894ef8

  I don't know if the dll is said to be thread safe or not. Also I do not understand how this causes a problem anyway since it is the only node that accesses the dll at the time, and each of the 6 spectrometers are interviewed in order?

  Is there anyway that I can still enjoy the benefits that the call of any thread dll provides without causing my application crash.

  An example of the increase in performance, it's that I can query the spectrometer from 6 to 70-80 Hz when configured to run in any thread, as opposed to a simple 10 Hz when the Run value in the UI thread.

  Thank you

  Looks like that the DLL is not thread-safe. If you do not run in the UI thread, there is no guarantee that the DLL will be always called from the same thread, even if you only call it in one no reentrante Subvi. By default, LabVIEW allocates multiple threads by the enforcement system, with the exception of the user interface. If the DLL stores certain information of one call to the other, this context can be lost when run in a different thread.

  Here's a thread that provides two possible solutions; a wrapper DLL is required, use the other the utility 'threadconfig' (or the corresponding INI file settings) to force a subsystem of a thread executing unique http://forums.ni.com/t5/LabVIEW/Force-DLLs-to-tun-in-the-same-thread-expect-the-UI-Thread/td-p/11438...

  Another option would be to put the call to the DLL in a timed loop that runs constantly, and you can use a queue or the notifier to pass data to. A timed loop runs in a single dedicated thread, so I think it will work.
