• Programmatically trigger cursor output?

  Hello

  I use the framework of the actor to develop a large application in LabVIEW. I have the sliders on a graph that trigger data be filled by actors using a structure of the event and a cursor output event. The data are also met (initialized) when the program starts.

  I currently do this initialization using a structure below and a change event of value on the "Init": Boolean

  

  also described here:

  http://forums.NI.com/T5/LabVIEW-idea-exchange/add-first-run-event-on-event-structure/IDC-p/1044975#M...

  The problem with the help of the 'init' Boolean is that I duplicate the same code in two events: "init": value change and "graph": output cursor events (the event two do exactly the same thing).  Does anyone know how slick combine these the Init event with cursor output event so that the cursor output event fires start? That way I wouldn't have to duplicate my code in two places...

  I've searched and have not found exactly what I needed, sorry if this has been covered somewhere in the forum.

  Taking place your common code? In case the Structure? Could register just for two events:

  

  Or to register for the event separately to send it to the nested actor:

  

• Problems using trigger cursor query and post.

  Hello
  
  I use a block non-base of data/model to query records in a database block. My form has a point text 'report No.' that will be used to enter a valid number of reports. Based on the number of this report, I hit a button to search (also from the same block of data non-base) to view records that have this "report No.' in the database block. I think I need to use a cursor in a post for this request but I am not able to operate :( Help, please! I really need this point that nobody is helping me to work:(la figure)
  
  My search button - button the trigger:
  DECLARE
  NUMBER OF CHOICES;
  BEGIN
  IF: DUMMY_BLK. NWTFR IS NULL THEN
  ALERTS. STOP_ALERT ("Start Date is required", choice);
  RAISE FORM_TRIGGER_FAILURE;
  END IF;
  go_block ('T_VESSEL_BLK');
  execute_query;
  END;
  
  My post_query:
  
  DECLARE
  cursor vessel_cur is
  SELECT VES_RPTNO, VES_SENDER, VES_SENDER_MBOX, VES_INTCTRL_REF, VES_NAME, VES_VOYNO, VES_ARRDT
  SHIP
  WHERE VES_RPTNO =: DUMMY_BLK. NWTFR;
  var_mot vessel_cur % ROWTYPE;
  BEGIN
  Open vessel_cur;
  LOOP
  extract the vessel_cur in var_mot;
  EXIT WHEN vessel_cur % NOTFOUND;
  END LOOP;
  close vessel_cur;
  END;

  instead of execute_query you do now

  Why do you offer me something like that? Replacing the standard behavior that you use forms must be well thought out, because you have to manage a large number of possible problems. You can easily get the desired using the standard logic behavior:

  -Create an item number IT_COUNT in a control block, assign 'calculation mode' to 'Summary', 'Synthesis function' to 'Count' "Down block" and your DB-bloc and "just point' a null-element not contained in this block. Last series the block 'Interrogate all folders' to 'Yes' in your databaseblock. Now, in your code, you can just checkl the value of this element of count, as

  ...
  EXECUTE_QUERY;
  IF :BL_CONTROL.IT_COUNT=0 THEN
    error
  END IF;

• Page loading and video stops until I have my cursor

  Recently I noticed every time a page refresh or I play any kind of video that both stop until I move my cursor, and then they start again.

• The mouse cursor disappears on the address and search bars.

  In Firefox 10, the mouse cursor disappears from the address bar or the search bar after a certain time, or I guess that after visiting a site that I paste below. I don't see what part of the word I click on the address bar or the search bar for the correction because there is no mouse cursor. After clicking on tools and options cancel, the mouse cursor appears (I make no changes to the options) or when I click on customize in the navigation bar, then the icons I click on Cancel again without modification, and the mouse cursor appears again (as you can understand some trigger for windows option implementation even without change is done). I uninstalled firefox 10 just for this reason. Back to Firefox 9. Safe mode - same problem happens. So no problem addon. And the same thing happened in another operating system, so this isn't a fault of a facility.

  Problem solved for me in the last version of firefox v.10.0.1

• cursor move reduced frequency of use

  Hello!

  Years ago, I remember I saw a post on the forum or a doc of the community, where he explained how to decrease a certain event that will be triggered too often.

  I have a graph with a slider, and when the user begins to move the cursor, I perform some minor calculations and some output in the indicators values. I would like to throw some of the events "moving the mouse", then when the user pulls the 'too fast' cursor, I have not to overload the CPU with treatment. I know that I could just use the 'release slider' event, but it is not only beautiful, the user does not receive feedback on values between the two locations.

  So I don't really know what was the thing to throw the too frequent trigger, it's a time stamp comparison I think...

  Could someone help me out, how to solve this task correctly?

  Thank you!

  In the new version of LabVIEW, you can limit the size of the queue of the event. Try this first. (See this completed idea).

  In the earlier version I compare the current position of the cursor with the position obtained from a property node and run a business structure empty, except if they are equal. The old discussion is here. (Also make sure to turn off "lock the front panel until the end of the event").

  The idea of cursor in this answer, see the right side of the next image.

  

• Automatically put the cursor in the text box to start

  Hi guys

  On the picture below you can see a small piece of my FP. It is a part of a bigger FP for a pretty huge electronics test. Each PCB got its own series number of barcode. I have a drive that is connected to my keyboard. Then when I read the code bar, numbers will appear in the text box on my FP, IF i first click on the text box. Then the user must only press START to do the test. My problem, or wish, if you like, is that when the program starts, or a test has completed, the cursor/marker is placed in the text box, so I just have to read bar codes.

  Currently, the user must click in the text box before you read the code bar. Is it possible that this can be done by Labview?

  I n node property checked yet, because I'm busy to something else right now at work. Just write in my break.

  

  Thanks for any help!

  PS I would have found the answer in the forum, but I am from Norway, and not all of the language of the computer is easy to translate since I use windows Norwegians. I belive that it is called cursor or marker however.

  Kind regards

  Hello

  The property node "KeyFocus" attached here brings the cursor automatically in the text box.  Set the "Val (Sgnl)" blank to trigger the event associated with this area of text (if necessary).

  I hope this helps.

  

• detect the movement of the cursor

  I have a chart 2D cluster, with two tables 1 d above and to the left (they have to input/output "alias" to set the line / 2D table columns). To fit everything on

  the user interface, I limited the number of values, with tables 1 d with cursors. I managed to 2D in sync with either the 1 d being indexed using their sliders, but only when I followed their "index value" in a loop of the index. What I really need, to fit my event driven structure is a way to trigger an event when one or the other parade, but have not been able to find something that triggers. Under the gun (aren't we always?)

  Working in LabVIEW 8.6, so if someone messages for example...

  Thank you

  Take a look at this and see if it's what you're talking about.

• Fire graphic cursor move event programmatically

  Is it possible to programmatically trigger the move bar graph event?  Assign a value to the Index of the cursor or the property node Cursor Position does not seem to do.

  Create a user and set up the case of the event which handles the cursor movement to handle that event as well. Then fire this event when the data updated?

• A trigger for give a discount of 10 percent for a regular customer

  Hello

  I am trying to create a trigger to give a 10% discount on the 'TotalCost' field in the table of reservations, if the 'statusname' is regular in the table of passengers. Here's what I come up with so far. But I know that its bad. Can you please help?

  create or replace TRIGGER Ten_Percent_Discount 
  BEFORE UPDATE ON Bookings
  FOR EACH ROW
  BEGIN
  UPDATE Bookings b
  SET b.TotalCost = 0.10 * TotalCost
  WHERE Passengers.StatusName = 'Regular';
  END;
  

  Thank you

  Fareedh

  Assuming you have a passenger_id in your table reservations probably use something like this

  Eate or replace TRIGGER Ten_Percent_Discount
  BEFORE the update ON bookings
  FOR EACH LINE

  CURSOR C_Passengers
  IS
  SELECT Status_Name
  OF passengers
  WHERE Passenger_Id =: NEW. Passenger_Id
  ;

  l_status_name Passengers.Status_Name%TYPE;

  BEGIN

  OPEN C_Passengers.
  Look FOR C_Passengers IN l_status_name;
  CLOSE C_Passengers;
   
  IF l_status_name = "Normal".
  THEN
  : New.total_cost = 0.90 *: New.Total_Cost;
  END IF;

  END;

• Difference between different "trigger events" in the form of customization

  Hi Experts,

  Can you get it someone please let me know precisely the difference between the various 'trigger events' (better with a simple example) in the form of customization in Oracle Apps?

  A TIME NEW FORM INSTANCE
  A TIME NEWS BLOCK INSTANCE
  A TIMES-NEWS-RECORD-INSTANCE
  ONCE - NEW - ITEM - INSTANCE
  WHEN-VALIDATE-RECORD
  1 by SPECIAL45

  Mainly, I'm confuse when use A TIMES-NEWS-RECORD-INSTANCE, WHEN-VALIDATE-RECORD and A TIMES-NEWS-POINT-INSTANCE (it will be that it is very useful, if it is provided with a simple example to understand the difference between these 3)

  Thanks in advance,

  Bommi

  Hello

  Once - new - form - Instance: this trigger is called just after form is called. If you can do what you need to do before the start of the form. Make sure that this trigger is called only when the form is opened.

  WHEN-VALIDATE-RECORD: this trigger is called when the cursor is moved off the current record of the block specified to another record. This trigger can be very useful when trying to insert or update a record under certain costraints. If conditions are true to this trigger and form_trigger_failure will pass under the situation has no validation, recording is not saved. Thus, everything works fine.

  Once - new - Record - Instance: this trigger is called when the cursor passes on a new record in the specified block. This trigger can be useful when it is necessary to set the computed value of an element at the level of each record.

  A time new point Instance: this trigger is called when the subjects in the forms is entered.

  Hope this helps,

• Tabular forms – test whether cursor/focus in the last line (Apex 5.0)

  I would like to optimize my sub fast data entry form. I have already added dynamic actions for Excel style and down navigation with up and down keys and also auto-insert new line when you press enter on the last field.

  The last thing that I want to achieve is to creata a dynamic action trigger that fires only when cursor is in the last row of tabular presentation. I tried to do that with the function. is() JS, but without success.

  Is there a way to test whether the current row (the row with focus) is the last line in the form of tables?

  Yes, look that I wanted to accomplish was that, if the cursor is in the last line (column_name1) that if the user presses THE button the last row is deleted and cursor is focused on the previous line (column_name2).

  After numerous tests that would be a DA who works for me:

  Event: Down key

  Selection type: jQuery Selector

  jQuery selector: .column_name1

  Condition: Expression JavaScript: (event.keyCode = $. ui.keyCode.UP) & (.closest("tr").is$ (this.triggeringElement) (": last-child"))

  Code:

  $(this.triggeringElement).closest("tr").remove ();

  $('input.column_name2:last').focus ();
