Dynamic transformations (Case statements) conducted through the user interface

Hello

I have a vision that a lot of business logic with values coded hard and would like to re - design the view make the transformation of dynamic business logic. I would like to give an example to tell the requirement in detail with the example below.

Example SQL view: -.

SELECT

A.EMP_ID,

A.EMP_NAME,

BOX WHEN A.STATE = 'CA' AND A.DEPT_CODE = "C123" THEN 10 '

WHEN ELSE A.STATE = 'NJ' AND A.DEPT_CODE IN ('N111', 'N454') AND A.GRADE = 'AAA' THEN '08'

ELSE END '00' AS TAX_RATE,

CASE WHEN A.JOIN_DT > = '20010101' OR (A.EMP_ID IN ('E134', "E456") OR A.DEP_CDE IN ('C222', "F222")) THEN '30'

WHEN of OTHER A.JOIN_DT < '20010101' OR A.EMP_ID IN ('J133', "K556") THEN '20'

ELSE '10' END AS BONUS_PERCENT

A.ADDRESS

FROM EMP A

WHERE A.END_DATE > = '20000101'

AND NVL (A.DEL_FL, 'N') = ' don't

AND EXISTS (SELECT DEPT 1 D)

WHERE D.EMP_ID = A.EMP_ID)

Result: -.


I wish I had the TAX_RATE and logic BONUS_PERCENT dynamically generated fields which has a lot of statements of case and hardcode, where the USER can change the logic and its values according to rank.

To do this, we can design a table EMP_BUS to have fields that can be modified and the transformation of the UI logic. Please share your ideas in the design of the table or the applicable...

Thank you in advance.

Hello

One way is to have all the settings defined by the user that is stored in a global Table Temporay and join at this table in your point of view.  The advantage of a global temporary Table is that each session has its own set of parameters which does not interfere with the other, so you can have multiple sessions using the view at the same time, and everyone will see the results based on its own parameters.

I hope that answers your question.
If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
If you ask on a DML statement, such as UPDATE, the sample data will be the content of the or the tables before the DML, and the results will be the State of the or the tables changed when it's all over.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  • How to get an array of integers to user in the User Interface

    Hi all. I'm not a very experienced user of the CVI. I have almost exclusively coding in LabVIEW but have a client who wants all of their work in the CVI.

    I've been very fruitful so far (set up a Modbus API from scratch that supports all types of connection) but am confused on how I can get the integer multiples of the user without limiting the number of integers I can get. Essentially, I need to be able to get an array of integers to the user.

    General information, I am building a user interface to test my Modbus API. There are Modbus functions to 'Write multiple registers' and 'write multiple coils. I want the user to be able to enter all the values they want to write in one command.

    What is the best way to get an array of integers through the user interface?

    The easiest way is probably to allow user input in a textbox control numbers: items can be separated by spaces, commas, or even a line break (using ctrl + Enter). You will then need to extract the string from the TextBox and analyzed for numeric values using any non-digit character as a separator: strspn (string, '0123456789'); can be used for this.

    More complex, another possibility is to use a table control to receive user input: you Dresses an empty table with a reasonable number of roews, or you need some codes to add new lines as long as the user fills all those already existing. On the other hand, it will be easier since data recovery in a simple statement, you will all return values: GetTableCellRangeVals (panelHandle, PANEL_TABLE, VAL_TABLE_COLUMN_RANGE (1), table, VAL_COLUMN_MAJOR);

  • Is it possible to add a hard drive to a VM running via a script or a program without using the user interface

    I'll try to ask this question clearly, but I ask that read you it carefully, because I can't do a great job of setting out clearly what I'm looking for.

    I know how to create a virtual disk in a batch file or a script.  I know how to have a running virtual machine to detect a newly added hard drive and format it in Linux, BACK, and NetWare. I do not have scripted this part, but I did it manually by adding records via the UI and then by doing the steps manually to make the operating system to detect and format the newly added drive. In each case, these steps are scriptable with the exception of the addition of the drive in the user interface.

    The only way I know to add a new hard disk to a virtual computer running is through the user interface. I don't know in a way that can contain script (for example vmrun or an API call) to make.

    I guess that maybe I can have the virtual machine to go into sleep mode and then add the HDD in the vmx file while the machine is in standby mode, then put the computer to sleep mode, although I have not tested this.

    My question is, ' can a virtual drive be added to a virtual machine running without using the user interface and without put the machine to sleep, or in other words in a script any?

  • After changing the default threshlod in the user interface, where it stores the new value?

    After I changed the value of the threshold warning/cirtical metric, I noticed there was a 'TARGET_TYPE' _ 'targetname '. XML generated in forlder $AGENT_HOME/sysman/emd/collection. It assumes that the registered here threshold has priority over that of collection.xml in $AGENT_HOME/sysman/admin/default_collection, right? I'm very curious, is if the new threshold is also recorded in some tables, the agent generates the 'TARGET_TYPE' _ 'targetname '. XML after reading the new value? If it is, could someone offer me the East?

    Thanks in advance!


    Thank you
    Satine

    The default collection file supplied with the plug-in is the basis of how the collection for the target type agent. If the user makes changes through the user interface, the agent record in a specific collection of target instance file that selectively replaces the default file in the collection.

    Data collection should be TARGET_METRIC_COLLECTIONS view of $ MGMT.

  • Structure of the case duplicates all the indicators on the user interface.

    I create a true/false case structure that contains several indicators for each of the cases respectively.  These indicators are displayed simultaneously on the user interface.  Is there a way to have indicators or indicators to replace the other as the other case is active or control must be in the user interface at the same time?

    Thank you!

    Is there a reason you want to duplicate the indicators?  The normal practice is to move the indicators outside the structure of the case and the wire coming from each case out through a tunnel.

  • Impressive transformation slow due to the updating of the user interface

    Hello

    I feel a huge slow down in my test as engine

    I update the display after each test. It consists of a rather

    "simple table" with a subtle change of color and bold

    to indicate the failure or success of the test:

    I have also tried several things to determine what routine was

    make the program almost crawling like a snail, here's my

    results:

    No UI refresh: 0m48s (same as Teststand with no updates of the user interface)

    The discount but no page table switch: 1m06s

    Bay of refreshment and switch page: 1m26s

    There are 314 tests, up to 314 redraw and possibly

    switch page 314 to reposition the view. Which gives the

    following user interface refresh costs:

    Update of the table: 18 years/314 = 57ms (replacing just a single line, Center to top)

    Switch to page: 20 s/314 = 64ms (bottom right corner)

    Is this really the case? Is there a way to make the refresh of the user interface

    faster? Create two separate loops/threads, one to make

    the test, one for updating the UI asynchronously?

    I understood for an overall picture about different

    David Koch

    Well, multi-listbox control is a problem if your change causes access to the muliple property node. For each property node LabVIEW normally does a refresh of the user interface which is very quickly. Fortunately, there is a fairly easy way to fix this.

    Use a node of property for the current VI (just drop a property node and change its class type VI Server-> VI reference) to get the reference of the Panel. Then use another property node connected to your reference of the Panel and select update from the Panel to postpone. Set this value to true before your Listbox (and any other updated user interface) and set the value to false then.

  • How to navigate through all of the links in the links Panel in the user interface?

    Hello world

    I wonder how I can browse all the links in the links Panel, programmatically. I have a document where the resources present in this Panel are not available using the ILinkManager. He tells me there are no links in the document when using ILinkManager-> GetLinkCount().

    These resources are not more related to any element on the page. These are images which are not more related to what it is. Right-click on it and click on 'join the link' shows nothing in the document (the same operation on a resource that is linked to a graphic image focuses on it). I can manually re-edit the link, but nothing more.

    In the user interface, there is no way to delete (not menu 'remove' or whatever).

    I think I "created" them as follows: during the creation of the story, the story is tagged. Then I attach a picture frame and label it in the history. Then I remove the frame (s) containing the history, so that its history xml is "not placed" (see kXMLUnplaceCmdBoss). At this time (if I'm not mistaken), I created these inaccessible resources. I see the xml story unplaced in the structure of the document that remains not placed XML (in the backup store) and resources in the links Panel.

    History unplaced XML CAN be removed manually, but not these inaccessible resources. However, there must be a way, as InDesign can display them.

    How to reach these 'lost' resources and delete them, by programming?

    Independent of your real problem, I would first try the equivalent in the user interface.

    Preparation:

    To simplify things and make them visible, working on a traditional tale - not the backup store.

    The story should be labeled and will remain so.

    Add content as complicated as you want.

    Some content preceding and behind it must survive.

    Your content must be labeled - surrounded by a single label.

    Text-Select this unique tag (see the invisible etc for the right selection).

    Remove the text selection.

    See: Tags are gone, content text disappeared, the images have disappeared.

    Now find a way to perform this deletion text programmatically. Without specific code XML - operation but a simple text, InDesign will do the rest.

    Finally, use the code that results on the backup store.

  • The best way to separate the user interface in the model LV 2012 queued Message Handler?

    If you create a new "queued Message Handler" new model 2012 LV, you will see a blue box in the case of "Update view" that says the following:

    Code Recommended - If you wish to decouple the Message Handling Loop from your user interface, consider creating User Events (like the "Stop" event in this VI) to message the Event Handling Loop whenever the user interface needs updating.
    

    I would like to give a suggestion, but I am struggling to find the best way to do this and still keep code modular.  The template creates a user - Stop.lvlib "event with a create/Destroy/fire Subvi.  I would like to create a library of "User event - Update UI.lvlib" similar with similar Create/Destroy/fire Subvi keep this new modular and separate user event.  The problem, I am struck, is that there may be only two hydrants in case Structure dynamic event so, how I modularlize creating user events in separate SubVIs and always maintain this dynamic event terminals?

    As a follow-up on the issue, it would be preferable to have a library of user by indicator events that must be updated or that a single UI update of the user and then event pass a cluster as the message that contains the name of the control for the update (to use with a structure of matter), then the data to go with it?

    Thank you!

    Instead of having the events to record in the 'create' methods, you could be part outside your 'create' SubVIs and then simply bundle them. Then, you create your individual event of the user management. See excerpt where I created a vi 'Create user event - Update' in front of the stop.

  • Need help with this code to update the user interface example

    I'm triying to understand the differences between the three methods to manage UI interactions.
    I'm really confused with these three terms when triying them figure out in a real case.
    Basically, I know that I should use invokeLater, invokeAndWat, or getEventLock() to avoid
    This exception: java.lang.illegalStateException: engine access UI without holding the lock on the event

    The code below illustrates the function of the invokeAndWait method, but if I replace it with
    invokeLater or getEventLock() the program will work exactly the same way.
    Could you please change the code to show the differences between the three
    methods of updating the user interface?

    / public final class HelloWorldMainScreen extends form {}

    private LabelField labelField;
    public HelloWorldMainScreen() {}
    labelField = new LabelField ("Hello World");
    Add (labelField);
    Thread MainScreenUpdaterThread = new MainScreenUpdaterThread (this);
    thread. Start();
    }

    {} public void appendLabelText (String text)
    labelField.setText(labelField.getText()+"\n"+text);
    }

    }

    SerializableAttribute public class MainScreenUpdaterThread extends Thread {}
    HelloWorldMainScreen screen;

    public MainScreenUpdaterThread (screen HelloWorldMainScreen) {}
    this.mainScreen = screen;
    }

    public void run() {}
    for (int i = 0; i)< 10;="" i++)="">
    try {}
    Thread.Sleep (5000);
    } catch (InterruptedException ex) {};
    UiApplication.getUiApplication () .invokeAndWait (new Runnable() {}
    public void run() {}
    mainScreen.appendLabelText ("Update");
    }
    });

    }
    }
    }

    These three concepts are very confusing for a lot from people so all explanatory source code
    describing their functions will be highly useful for everyone, I think.

    Thanks in advance!

    With respect to the effect, there is no difference between methods.  The difference is the way in which the result is achieved.  So we can't change the code to show you the difference.

    As we are unable to demonstrate the difference, you have to do with an explanation.  To understand the explanation, you'll need to understand the thread of events, so if you have not already, please consider this:

    http://supportforums.BlackBerry.com/T5/Java-development/what-is-the-event-thread/Ta-p/446865

    If the three options are differentiated by the processing order:

    (a) invokeLater executes the update on the thread of events.  The transformation takes place at a later stage and the code which is in order after the invokeLater will actually run before the code within the invokeLater.

    (b) invokeAndWait also manages the update on the thread of events, which means that all other events that await on the thread of events will be run before this code.  But any code after the invokeAndWait will not be executed.

    (c) the synchronized option, like invokeAndWait, runs the update of the UI before moving on to the following code.  The difference is that the code to run on the event Thread is not executed before code in the synchronized block.

    If this is meaningless, so that probably does not matter too much.  in general, you should use invokeLater, except if you need to update the user interface occur in the order with your background processing.  If so, use invokeAndWait. It has synced are very few occasions where you must use the block, and it should be very small updates to the user interface and you should understand the implications this could have on the wire events.

    To my UCM_Server1 content WebCenter.

    As I already have a WebCenter content I have to follow the second part of the note

    How to install and configure the UI content with WebCenter content 11.1.1.8.0 and 11.1.1.9.0 (Doc ID 1618305.1).

    Install and configure content WebCenter ADF WebUI against WebCenter Content Server

    Step 1) install the MDS schema

    (Step 2), install the Weblogic Server

    11 GR 1 material step 3) DOWNLOAD and install Oracle Application Development Framework (11.1.1.6.0) in the new WebUI WLS Middleware House, found here

    Step 4) Download and apply Patch 16, 546 129.

    Step 5) Download and apply Patch 16, 546 157.

    Step 6) download and apply the Patch and then 19,469,801, 18,102,108 Patch

    Step 7) copy the wccadf files in the field of user interface

    Step 8) Oracle on demand services (MDS) metadata registry

    Step 9) Place the WebCenter content domain user interface model

    Step 10) run the Setup Wizard on the new home of Middleware WebUI to create the new domain

    Step 11) updated the Oracle ADF of shared libraries

    Step 12) start the domain WebUI administration server

    Step 13) Save target Managed Server with the MDS repository and create the metadata partition

    Step 14) start the server managed WebUI.

    Step 15) associate UI WebCenter content to Content Server.

    Step 16) reboot the WebUI ADF server managed.

    Step 17 access the WebUI

    Step 18) complete the Configuration of the workflow

    Step 19) apply the latest Patch Bundle content UI of WebCenter

    MY DOUBT IS:

    To read the steps that I understood, to 19, with success, in the end, I will have an another WebLogic with a domain name and its respective EM.

    I have two servers weblogic?

    portal_domain (explained above) and a new wccui_domain wls and domain.

    This fix it?

    Two WLS to keep WebCenter portal and content, and other elements.

    Because I'm not able to do with the WLS even where I UCM_server1 today?

    Thanks for all suggestions and criticism.

    Yes, up to 11.1.1.9.0, you will need to install a new wls House (new wls server admin) and then configure WCC ui there. User interface and COE will not work in the same field. You can have the portal and content under the same House of wls and install a new one for the user interface.

    This is due to a problem with ADF and WCC libraries.

    With 12 c, this dependence is not there, and you can install / configure all 3 (Portal, content and adf ui) applications on the same domain.

  • Interact with the user interface components

    I'm trying to find a GOOD way to interact with the external classes user interface components. For example, that you have a 'controller' class that needs to access the view of the user interface in some way (define a label text or something else). The controller class does not do anything, it discusses only the logic of what should be the case. Currently, it is created by my top-level class when the program starts. He listens to some events occur and needs to update/interact with the user interface or the State of the application depending on what events are. I do not seem to be a way for this controller class to easily access the UI component that I need to get my hands on.

    I'm trying to do to reduce the size of a file of mxml WindowedApplication growing (LOOK cool but that is not important) and take part of the logic of the application of this file.

    It's complicated by the fact that the label is in a State that does not have the status of 'base' (so it is not a child, or even a subsidiary child of the main class at boot time) and by the fact that it is not yet near a high school component. (If that were the case, I could probably just pass the label object in the constructor for the outdoor classroom.)

    In other words, I can't just call getChild ("labelName") on my 'main' request object because it is buried nested inside OTHER components. I don't think I like the idea to browse all components and sous-composants recursively looking for the component that my outer class trying to ask. I thought about other ideas, but I don't like any of them enough to try them, eh.

    I'm at the point now about where I come to the conclusion that my fundamental design strategy is wrong, or Flex just not allowing complex applications where the GUI components can interact with external classes relatively pain-free. I'm not convinced that "Flex cannot do', I'm looking for advice on some great Flex application in all design patterns.

    Where do you put this kind of control logic, and what happens when it starts to overflow and become so large that you need to break in other files?

    Found a solution, I think that's what I've been looking for:

  • Flatten to a string to send arbitrary objects by messages from the user interface?

    Hi people,

    I am trying to send arbitrary data by messages from the user interface defined by the user to my labview interface. Something funny happens then: if I send the data through the message of ui, it seems I have something strange. There is only one character or nothing in the message of the user interface that reached my reminder.

    It seems that flatten channel also creates control characters that are interpreted by NI TestStand and Labview not as members of the chain, and for this reason I only get incomplete data. within the action of testand, which creates the flattened data, I put a dialog box to display the string data, and it seems that at least up to 255 (ascii) characters are used.

    Is there something like uuencode/uudecode to avoid this problem?

    Thanks in advance

    Okidoki, found.

    His «binary"produced by «Flatten the string» string Apparently I thought, the LabVIEW data type is incompatible with the API of TestStand from LabVIEW. In conclusion I would classify this as a bug (sorry people, at least there should be documentation) API for LabVIEW TestStand 2014.

    As a solution, I use flatten it in XML, which is a printable and human readable 'normal' string.

    It was trial and error, and I'm not enjoying this.

  • How to get TS::SequenceContextPtr to customize the user interface

    I want the file of the custom, user interface sequence value therefore need to take stock of the TS:equenceContextPtr, anyone know how to get this point.

    Is there a reason that UIMessages are not enough?

    Just off the top of my head, here are a few concerns with the not not using UIMessages:

    1. How the user interface is unknown when the file of the sequence is developed to set the value.  Without an event or some sort of synchronization you can do exactly that.  UIMessages not only to ensure the right information, but they help also with synchronization.

    2. The engine does not know this information, and view of execution manager knows that the information for the current execution it is linked to (which changes throughout the life of a series of tests).  Basically, recall of front end, model, and other factors may spawn short executions briefly related to the Manager view of execution.  So if you take the context of the sequence of the current run is perhaps not the right one.

    3. Writing a user interface will be couple the user interface to your specific sequence file.  At this point, you can use the network variables or global variables or global queues as well.  It might even be better options.

    The situation you describe is exactly why the UIMessages were created.  Maybe you can help me understand why you are set on the use of pointers, you already have?  There might be a better solution for your case if I'm misunderstanding you.

    Thank you
