  Here's my problem:
  We have a table that contains metadata about the files (paper or electronic).
  We hope that we can need more columns in the table at some point and do not want to change the table or the application.
  
  So to do this I would like to create:
  
  A table called TBL_FILE with columns:
  NUMBER of TBL_FILE_ID (this will be the primary key)
  TBL_FILE_NAME VARCHAR2 (1000) (this will be the name of the file)
  
  A second table will be called TBL_FILE_META with columns:
  NUMBER of TBL_META_ID (this will be the primary key)
  NUMBER of TBL_FILE_ID (this will be the key to forign to the files table)
  TBL_META_COLUMN VARCHAR2 (30) (this is what would be the name of the column if it existed in TBL_FILE)
  TBL_META_VALUE VARCHAR2 (1000) (this is the value of this record and the column "would be")
  
  If a person can have as many meta data in the file to add columns to the table.
  The problem is how can I allow users to add as much data as they wish with them having to re develop page.
  
  Other things to note is that we would like this be on one page.
  I know how to add we can create inserts several rows using a SQL (editable report).
  However the TBL_META_VALUE in the TBL_FILE_META column will sometimes be a selection list and other times one text box or a numeric field.
  So I don't see now a SQL (editable report) would work for this and I can't create a table of elements on the page running I can?
  
  No idea how I might accomplish this? Is there a better way to do this?
  
  It is a term or a name for what I'm doing by creating these "virtual" columns in another table?

  Yes, you can do it. Update report / query in a table can be built from the metadata using the SQL query that returns the PL/SQL function . It will be a bit of coding in PL/SQL where you use metadata and metadata of Meta data to restore your SELECTION with the right APEX_ITEMs. He might have a decrease in performance associated with it, but it will not be a serious degradation.

• Add fields dynamically during execution

  Hi Experts,

  Is it possible to add fields to the form layout during execution. say at the click of a button similar to the Acro forms where we addFields() and deleteFields() methiods. InstanceManager can add subforms, but it is possible to add fields at run time.

  Kind regards.

  Rohit

  Subforms by themselves do not nuch... .they contain content (as fields), so when you add a subform you're actually adding content in the subform. So to answer your question, you cannot dynamically add a field, but you can add a field indirectly by adding a subform.

  Make sense?

• Can I change dynamically during execution Data Source?

  I need run the same reports on test environment and the production environment. How could I change source data during execution, according to the users want to run reports by querying the database test or production without amendment report definition?

  Hello

  what I would recommend in your case: set up your development/test systems as separate systems parallel to your production system. Clone your production environment for these development systems. Then a developer can login to the development system and run the reports (and modify it without touching the actual production system) and normal users work on the production system and only for validating them new developments, that they connect to the test system.

  It's a standard approach in software development and COMPUTER systems operations.

  How to watch your infrastructure, I have the impression that you have two databases and Server BI (prod and test)? Why not set up a test environment for the BI server, too?

• When the sequence of process template client file is loaded for execution?

  As part of a custom process template I've created, I would like to make a few changes in the sequence of the client before file called by the process template. These changes will be then be restored after the loop finishes USE (I'm changing the sequential model).

  Another thread, I discovered that TestStand sequences cannot be edited structurally once they have been loaded for execution. My question is: what is client sequence template process ' for execution "?

  After some research, I discovered that the sequence of the client file is not locked to prevent changes to the sequence editor until the "Reminder of the main sequence" sequence step call runs in the model process entry point. At this stage, the sequence of the client file is loaded dynamically as the module at this stage.

  However, before this point, there are two places that the file of the client's sequence is used, and I want to assure you that they don't 'load the customer file for execution.  The Runstate.ProcessModelClient property is a reference to the object the client file SequenceFile and exist as soon as the entry point is called. In addition, the engine must know about the sequence of the client file to correctly call reminders of process model. Do any of these things make the movie of 'responsible for performance customer file?

  It boils down to this: can I do safely from the structural changes to my file of sequence of the client during the ProcessSetup and ProcessCleanup?

  According to the information I found in another post (see the comments of Eric_Crank on page 2), it is allowed. However, in this case customers were only make changes to the property Data of the RunState.ProcessModelClient. I want to assure you that I can use the TestStand API on the reference too.

  Also, just FYI, I got this works. I can add steps to the sequence MainSequence customer sequence file of the group stage of installation of the point of entry of the process model via the API TestStand. I ask here if make sure that it is a safe thing to do, and that there is nothing I plan not to.

  Thank you.

  Josh,

  If your sequence allows the option "optimize no concave calls this sequence", the first time the sequence run TestStand stores a copy of the execution of the sequence in a cache associated with running. As long as the sequence is in this cache you can not change, and TestStand considers that the sequence for 'run' file (see the SequenceFile.IsExecuting property). You cannot unload 'enforcement' sequence files (see SequenceFile.CanUnload). Sequences remain in the cache until it is closed. There is no way for you to remove the sequences of this cache, but you can prevent them to be added to the cache by turning off the option "optimize... ». Disabling this option should have no impact on the performance that you call the sequence only once.

• Restyling PieChart during execution

  HY
  
  I can style a pieChart with different colors when has these CSS commands:
  .default - color0.chart - pie {-fx-pie-color: #8A2BE2 ;}}
  .default - color1.chart - pie {-fx-pie-color: #A52A2A ;}}
  
  but when I load a file different css during execution with different colors
  
  .default - color0.chart - pie {-fx-pie-color: blue ;}}
  .default - color1.chart - pie {-fx-pie-color: #696969 ;}}
  
  the style is not changed.
  
  I can start my App with those of its work very well in the right colors.
  But I want to dynamically change color over time and not when you start the application.
  
  Are there other elements in JavaFX 2.2 where style is changed only if
  a different css is loaded on startup of the application?
  
  BR and thanks for the tips

  It seems to work if you apply the style sheet to the root of the scene, rather than the scene itself, or indeed as the pie chart. (It is not clear to me why it does not work on the stage.)

  In fact, you probably want to make the smallest possible part of the graphic scene (Camembert), because you will probably have a bunch of other styles to apply to the different parts of the stage, and you do not want to erase those every time. So do

  public void switchStyle1() {
    myPieChart.getStylesheets().clear();
    myPieChart.getStylesheets().addAll(cssPath + "custom1.css");
    styleType = EStyle.customStyle1;
  }
  

  etc.

• definition of the background image of the file during execution

  So, I have another issue to resolve and my migration to 11.5 will be complete.  In the previous iteration, the project has been able to set the background image from an external file dynamically during execution.

  After the migration, it seems that the projector keeps the canonical path to the image of Member and looking for him there. In other words, loads of projector, but a file finder opens, saying: he cannot find the background image in the path of the source machine Director.  Setting the name of the file in the jargon does not stop this behavior doesn't happen.

  I tried to re - import the image as "link to external file" (which had the same results) and flat import (which does not load the file during execution, even if I put the file name in the jargon).

  Anyone know how I can do this, the value of the background image of a file during execution?

  Thanks in advance!

  I do it all the time.  Just make sure that the image is in the same location relative to the projector that's director file.  The easiest way is of course if the image is in the same folder as the .dir file, in which case, you'd sure as to put it in the same folder as the projector, and you can set the name of the file using:

  Member ("someExternalMember"). FileName = the moviePath & "filename.jpg"

  You can have it in subfolders as well if you want to make sure that the relative location is the same.

• Is it possible to remove a dynamic class properties?

  I have a dynamic ActionScript class that allows you to send parameters to a Web service. Some of these settings are still present, so that they are public properties of the class:
  
  package
  {
  [Bindable]
  public class dynamic WebServiceCriteria
  {
  public var property1:int;
  
  public var property2:String;
  
  public var property3:String;
  
  public var property4:String;
  }
  }
  
  But, I also add properties during execution that can change over time:
  
  criteria.runTimeProperty = "1";
  
  I'm not very familiar with the use of dynamic classes, so I was wondering if it is possible to 'remove' the new property. Let's say that the next time I call the Web service, I don't want the property sent - not even not as a null value. How can I remove it from the instance of the class without creating a new instance every time?
  

  Hello

  Please try to remove criteria.runTimeProperty. You can find more information about the operator delete the address below.

• modify VI during execution

  Dear users of LabView,

  I have a fairly general question about the development of a project, which requires a continuous control of the material. To be more precise, I develop LabView control and DAQ software for calorimeters in high volume in the last 2 years. Such a system requires several PID controls, and it has many subsystems. Because of the large heat capacity, it takes about 3-4 days to launch the system. So if I need to edit for example something in control of the final of a specific subsystem, I stop the LabView code, I have change the specific part, I restart the system, I wait for 3 days, and then I can see the result of my changes.

  My question is the sort of General: what is the good, let's say "best practice" to avoid such a dead time?

  Is it possible to change a VI during execution?

  I understand that if I run the independent screw, that dealing with subsystems, I could avoid this problem. But if I already have a compact 'main' VI, including all the subVIs, what can I do?

  It would be nice to have a sort of "hot swapping" feature in LabView, so during the execution of main VI of my project, I could change the Subvi that I want, and when it is ready to activate, the runtime would swap with the old version.

  Thanks for the tips and advice!

  Best wishes

  Hello

  It all depends on how works your vi...

  The only way I see is to use dynamic calls: a vi called dynamically is editable even if appellant vi is running.

  If you change the callee until the caller calls the vi vi.

  Is how the appellant under vi (this includes the values of connectors and run the VI):

• During execution of the backup and maintenance on one of my computers, I noticed a folder and the file that I can't identify me...

  Original title: identity of unknown folder

  During execution of the backup and maintenance on one of my computers (Windows xp home, sp3), I noticed a folder and the file that I can't identify.  The name of the folder is cc68f6b7a7ca948eefb018f001 and the name of the update.exe file.  The properties of the file that it is a Windows Service Pack installation.  I tried Googling the name of the folder, but found nothing.

  Can you tell me with regard to this issue, and what, if anything, I have to do?

  Thank you.

  When some programs (including Windows) installs things, it can create a temporary folder composed of 20-30 random letters and numbers or random numbers and letters in the root of the drive of the volume with more free space.

  This explains why the records are sometimes on your C drive or any other drive - the most space?

  For example, you can see a similar to or called folder:

  D:\9470bb12e8a4f3447657236478e41c5

  There may be other folders and files in this main temporary folder such as amd64 and i386 platforms.

  They should normally be deleted when the installation is complete, but sometimes they are not - especially if the installation fails.  They are harmless but annoying.  You can think something is wrong when there are no or fear, that the files are really necessary.  To avoid confusion, you can delete the temporary files.

  If your installation has failed or the installation does not remove the folder to the random name when it finishes running again installation will be another folder at the random name.

  You may be able to identify installation (out of curiosity) by looking at some of the contents of the folder and decide if this installation was not serious, just remove the files/folders.  If the installation does not work for some reason, run again just installation will create a new temporary folder to the random name so the old temporary folder is really useless.

  Records are sometimes tough to remove.  Even if you are an administrator on the system, you might get a "sharing violation", "access denied", "used" or type similar message when you try to delete temporary folders.  Facilities sometimes use different permissions that can have a regular user with the administrator group.

  There are many methods to try to remove the folders, and some require third party programs to install or change some windows settings that could compromise the security of your system if you do not change them back when you're done.

  Start your system in Mode safe mode (by pressing the F8 key several times just before XP attempts to load) is one good method to try to remove the files because it does not have to make any changes to your system configuration or by downloading third-party programs.

  If you are running XP Home Edition, the following section on turn off "Simple file sharing" does not apply to you since in XP Home, Simple file sharing is always turned on.  If you are running XP Home Edition, skip the next few paragraphs and resume where it says:

  "If no part tool above work try a third popular called Unlocker.

  If Safe Mode does not work you can change the security of the folder when you start in Normal Mode to give your username full control over the files by navigating to it in Solution Explorer, click on tools, Folder Options, view and in the advanced settings window, uncheck (at the bottom of the list) use simple file sharing (recommended) and click OK.  This disables him recommended simple file sharing on your computer if you want to turn it back on when you're done to make everything you do.

  Right-click on the files of interest, click Properties and click the now visible security tab.  Change the properties, but you need (for example, select your user name, and check the box to allow full control), click OK to apply the changes.

  With usage share of active simple files (recommended) the checked the properties of the folder tabs are:

  General, sharing, customize

  With the use of sharing files simple disabled (recommended) box unchecked, the properties of the folder tabs are:

  General, security, customize

  Now, try to manipulate/delete the folder.

  It's a good idea to go back to the Explorer and the cheque in the box easy to use sharing files (recommended) when you have finished making everything you do.

  If none of the above works, try a popular third-party tool called Unlocker.

  Unlocker can be downloaded here:

  http://www.emptyloop.com/Unlocker/

  If you use Unlocker, be sure to install because he wants to add a bunch of options, addons, shortcuts and other extras that you don't need.

  You must add the shell extension so when you right click on the offending file, you will have a Unlocker option to choose.  I would just install it long enough to clean up the leftovers and then, I usually just uninstall and all parts of it.  You can always install it again another day if you like.

  Unlocker can be uninstalled when you have finished using it.

  Reboot when finished to ensure that boring records are really missing.

• Filter the Table during execution and keep uncommitted line changes

  Hello

  I have a requirement which has been quite difficult for me so far.

  I use the first version Jdev 12 c.

  I have a table of AF that is connected to a ViewObject that is used for sending new data.

  When I add lines to this ViewObject, I put a field that I intend to use for filtering so that the number of lines is not displayed at the same time.  This field comes from a selection of LOV.

  I want to be able to change lines are displayed in the table based on what is the current value of selection LOV.  This isn't a problem for me, and it works perfectly using a view criteria and a variable transitional EO I put in place.

  My problem is that when I select a new value in the LOV and change to bind the variable view criteria, I want all changes uncommitted to the lines to be preserved in the View object.  Currently, the lines are not keep their changes, and I need to do this, because after that the user has entered data for a large number of lines, there will be a commit to the database for all new lines added.  Is this possible or should I look for an alternative?

  I also tried to use a table filter in the link of the page layer, but I get an error that I can't debug. It is marked as Houston-34014.  In this method, I try to access my bean in pageFlowScope to filter the table.  This bean variable is updated when the LOV selection changes.  Error messages settings are {0 = oracle.jbo.Key [-220-225], 1 = root}.  I also read that this filter parameter is a static filter and does not dynamically during execution.

  Any help would be appreciated, thanks for reading.

• Problem with the compilation by using the new compiler (Compilation failed during execution: compilation-abc)

  Hello

  Since the release of the fast compiler, I experienced problems with the compilation of the version release with it.

  As it was still in beta, and since it was still possible to use the legacy compiler, I chose to use the legacy compiler each time (especially since it was more stable).

  With this 64-bit iOS requirement came into play on February 1, the legacy compiler is no longer available because it has been completely removed from AIR 16 (and all future versions).

  Now, I can no longer compile release versions (debug versions are works well) because I have the following error every time:

  Error occurred during the application of packaging:

  I tried to pin-point the source of the problem leaving specific things in the code, while removing all the rest,

• Fill the programmatic view object during execution

  Hi all

  I have a requirement to switch between the three different data source during execution in a single page. The user interface and the field names are the same for these three cases, but data from various sources (queries).

  So, imagine that we have 3 objects in view which has implemented read-only (object request depending on the view) and we want to fill a display object at the main performance as a data source for my page.

  My idea is to use "Prgorammatic view object" for this data source and then fill dynamically the contents of one of the three objects view read-only based on a setting in the user's selection.

  First of all, I want to know if it is thin approach and if yes, then get some points on the implementation or any other sample.

  I found this example:

  http://techiecook.WordPress.com/2011/05/17/programmatically-populate-view-objects-in-Oracle-ADF/

  Thanks in advance,

  Nasser

  Hello

  It is more a case of use for Adaptive connections. See:https://blogs.oracle.com/groundside/entry/towards_ultra_reusability_for_adf

  You can use EL to change the name of the ViewObject that an iterator in ADF queries its data. If the switch is on the link layer and there is no need for programmatic view objects. Unlike in the article of the blog above, VO 3 exist in your case then you don't need to create on the fly. Just change the name of VO in the managed bean referenced
