  SP2-0552: Bind "BV_COLOR" variable not declared.
  
  

  This is the way of declaring bind variables in SQL * more.

  In a PL/SQL block, you do not use bind variables like SQL * more. You just use normal variables. The PL/SQL engine is smart and sends SQL statements to the SQL engine containing all PL/SQL variables converted to bind variables. If it works transparent in PL/SQL and you don't have to do something more.

• change the same variable in different loops

  Hi all

  I use an event producer/consumer-controlled architecture where the two loops run processes acting on a common variable.

  To be more precise, I intend to change a flag photo in the loops of consumer and producer. That's why I need to share this variable between the two loops.

  I thought that the best way to do this is to use the indicator of functional photo as part of a Global Variable:
  1 / FGV initialization, which is a cluster that contains the indicator image

  2 / in two loops, the image indicator last value is extracted from the FGV using an action of 'read '.

  3 / the value of the indicator of picture is wired through different processes that would change partially or totally

  4 / Finally, in two loops the photo update flag values are wired as input to the FGV.

  Above is the ideal case, I expected to work. However, this does not work, and is what I've actually implemented:

  (a) in the loop of the producer, the indicator of picture is updated via a shift register, and at the same time, the new value is stored in the FGV

  (b) in the loop of consumption, the indicator of the image is retrieved from the FGV, and its present value is stored in the FGV (as in the ideal case)

  Then I don't why it does not work. I use other FGVs in my VI and which are modified by two loops, but THEY work...

  My VI is really great, so I can't take a picture of him. Can I give you a diet simplified what is my current architecture, whose shot at him. I hope it helps.

  Thank you.

  Hi Florian.

  Two FGV reads on the left side of your curls below will be a problem unless you use the data flow to control. The FGV bed (as shown) will occur at the start and then after the structure of each loop ends. When you really want to 'read' when Gets an element from the queue or in the loop of photo - when there are new values.

  The loop of consumption is fairly easy to treat. Just run the Dequeue 'error' error 'in' on your FGV. This will ensure that playback of the FGV happens when you get a new item.

  The photo event loop is a bit tricky. You could send a user of the consumption loop event (after your FGV write) to the photo event loop. In this case the user loop photo, put a reading of the FGV. This ensures that you will get the changes made in the loop of the consumer. The only downside to this approach is that the photo loop always runs once when a change is made in the loop of the consumer. You can use a Boolean value to prevent the image to be written (ensures also the image is always written after the end of the event Structure).

  Here is an example:

• by the way the variable counter between the loops

  I have a question about the passage of a variable counter between different events / while loops and seen an increase in value regardless of the loop is initiated.

  The fundamental problem is that I write file names unique to data collected on a spectrometer, and I would value at the end of the name of the file to increment every time that I collect the data. There are several different ways that I can collect the data, and I'd like the counter to increment when the collections is triggered. The attachment shows essentially what I'm trying to accomplish. Represent it buttons collect two different types of data I collect my instrument, but the counter variable is not passed correctly between the two loops. Is it possible that I can get the incrementing counter so that the two loops read the same value of counter?

  Thanks for your help.

  I can't look at your code since I'm on a phone. But you should really only have / need a structure of the event in a vi. The only exception I can think of is one to manage the events of the user and the other for GUI events. But even in this case there is no reason that I can think to need two.

• Declare the Variable step in a package

  Hello

  Is it obligatory to declare a variable in a package, even when we are refreshing or set the value of this variable in the package? What are the problems that occur in the case where a variable is not declared in the package?

  Please note that I understand that the variable must be romance in the package in case it is not be refreshed or set or incremented but is used by any step in the package.

  Thank you and best regards,

  PV

  Hi PV.

  You must declare a variable, unless it is explicitly used in the package to arm, refreshing or evaluate its value (as you mentioned).

  You must declare also specifically when:

  • You want its value to be passed during execution (runtime scenarios)
  • You want to use in the name of the resource to a data store in a scenario

• Cannot be used for the loop variable 'i' twice?

  Something weird is happening with a dialog box that I'm doing that dynamically creates buttons based on the number of objects in a table that I pass in a function. I say weird, but it's obviously me not understanding how the variables in a loop. See below:

  mrp = {
      one: [new File("/Users/constantincerdan/Creative%20Cloud%20Files/Templater/Iconbuttons/bagspouches.png"), "One"],
      two: [new File("file:///Users/constantincerdan/Creative%20Cloud%20Files/Templater/Iconbuttons/beauty.png"), "Two"],
      three: [new File("file:///Users/constantincerdan/Creative%20Cloud%20Files/Templater/Iconbuttons/bluepocketsquare.png"), "Three"]
  }
  
  function Dialog(dialogTitle, buttons) {
  
      var dlg = new Window("dialog", dialogTitle + " - OU");
      dlg.margins = [20, 15, 20, 17];
      dlg.buttonsGroup = dlg.add("group");
      dlg.buttonsGroup.orientation = "row";
      dlg.buttonsGroup.spacing = 15;
  
      for(var i = 0; i < buttons.length; i++){
          templaterButton = dlg.buttonsGroup.add("iconbutton", undefined, buttons[i][0])
          templaterButton.onClick = function(){
              open(buttons[i][0])      
              dlg.close()      
          }
          dlg.buttonsGroup.add("panel", [undefined, undefined, 0,120])
      }
      dlg.show()
  }
  Dialog("Test",[mrp.one, mrp.two, mrp.three])
  
  
  
  
  
  
  

  Execution of this poster dialog very well, and all the icon buttons have their own photos as they should (see photo below).

  This is what confuses me: line 16, he is able to use I on the buttons [i] [0] very well get every image and use it, but for some reason any when I also try to use the same thing to line 18 to try to open the real images for each button, I get the error "undefined is not an object" on this line. Change key [i] [0] to line 18 to the key [0] [0] opens the first image very well (on three keys), so I can't understand what I'm doing wrong here?

  

  The problem is that the function that executes the dialog box is not a variable that I exist. It is a function that get-called on the fly. One thing you can do is to use 'this' in the service running, so it will point to the iconbutton that you clicked on, unfortunately there is no default property of this button that can point to the actual file, there is only the property "icon" but that only gives the name of the file and not its full path , but you can create a custom property that can point to the path to the file like this:

  MRP = {}

  a: [new file ("/Users/constantincerdan/Creative%20Cloud % 20Files/Templater/Iconbuttons/bagspouches program. PNG"),"One"],

  two: [new file ("file:///Users/constantincerdan/Creative%20Cloud%20Files/Templater/Iconbuttons/beaut y.png"), "Two"],

  three: [new file ("file:///Users/constantincerdan/Creative%20Cloud%20Files/Templater/Iconbuttons/bluep ocketsquare.png"), "Three"]

  }

  function {Dialog (dialogTitle, buttons)

  var DLG = new window ("dialog", dialogTitle + "- OR");

  DLG. Margins = [20, 15, 20, 17];

  dlg.buttonsGroup = dlg.add ('group');

  dlg.buttonsGroup.orientation = "row";

  dlg.buttonsGroup.spacing = 15;

  for (var i = 0; i)< buttons.length;="">

  templaterButton = dlg.buttonsGroup.add ("iconbutton", undefined, buttons [i] [0]);

  templaterButton.myFile buttons [i] [0] ;// = my custom property

  templaterButton.onClick = function() {}

  App.Open (this.) MyFile);

  Open (this.) MyFile); / / use the property of the selected object

  DLG. Close();

  }

  dlg.buttonsGroup.add ('panel', [undefined, undefined, 0,120])

  }

  DLG. Show()

• Variable to URL in the list of the loop

  How could refer to this variable in a loop?

  #URL.p [i] #.

  Almost.  If your url variables are named p1, p2, etc, the syntax is:

  #URL [' p #i # '] #... OR

  #URL ['p' & I] #.

• The possibility of declaring the variable on request?

  Hello
  
  With the help of Oracle 9i. I'm new to the PL/SQL (coming from c#), I would like to know if it is possible to declare a variable around the where it is used. For example, in the execution of the procedure block, suppose I want to do:

  vTest whole;
  vTest: = 123;
  
  .. existing code (continued)...
  
  In doing so, the procedure could not compile. The only way I know to date is to declare the whole vTest. in the declaration block. Can you please let me know how to declare the variable in the body of the procedure?
  
  Thanks in advance.

• Value of the loop variable for begins with the last entry of the previous run

  I have a problem with a loop for... I am a beginner with Labview and perhaps do not follow the order of events (since it runs not on a line-by-line as typical of programming languages), but I think that my problem is trivial.

  Say I'm running a loop for 16 iterations and I want to build a table which, for example, consists of four 0s, 1 4s, four 2s and 3 four s.   I initialize the array outside and using shift registers to be added to the matrix in the loop for.

  However, the first time I run the program I get funky results.  In subsequent runs, the first value in my table is a 3, and the rest of the rest of the table is moved down by 1, so I did that three 3s at the end (for example).

  Can someone help me understand how to solve this problem?

  Thank you

  Hello!

  I have the following documents open in Photoshop:

  869548_mrp_ou. TIF

  896589_mrp_in. TIF

  896589_mrp_ou. TIF

  var originalPid = 896589
  for(i = 0; i < app.documents.length ; i ++) {
        activeDocument = app.documents[i]

• How to make a loop with variable values depending on where you are in the loop

  Hello

  I need loops / nested loops that choose different figures depending on where you are in the loop.

  The entire function must operate at times 'ml '. 'ml' is a dynamic figure.

  Loop 1 = while the loop is the first 12 iterations, "exconemp" must be equal to 100. 13-24 iterations, 'exconemp' to 102.5 equal, for 25-36 TI 105.06, 37-48, it will be 107.69. This must change each 12th iteration until he reached 'ml '. The calculation takes the value of the previous 'exconemp' and then that multiply by 0.025.

  Loop 2 = while the loop is in 120 first iterations, 'abc' should be equal to 0.015 and additional iterations should use 0.01. It should also work in a way to know if 'ml' is greater or less than 120 and work accordingly.

  My main problem is - this - how can I get loops to go like this:

  While the iteration is < 12, to do this, THEN take the final figure (12th iteration) and begin the 13-24, make this SO etc etc.

  How to produce a THEN statement? I can get the code to pick up the final values, but does not change along the way.

  I think I might better create an array for loop 1, but I'm not entirely convinced of that. Also, I think it would be better/more net if I can get "month total 1 ' and ' month 2 total ' in loops, but do not know how to do this.

  The values I need to produce (only 36 first shown):

  1-12 = 125.55, 251,65, 378.31, 505.52, 633.29, 761.63, 890.53, 1019.99, 1150.03, 1280.63, 1411.81, 1543.57

  x_error_msg OUT Varchar2

  )

  In the above procedure, I had the VALD_TBL. Is it OK?

  And how in the loop if the records if I use:

  FOR indx1 IN 1.p_lot_number_list. COUNTY

  LOOP

  BEGIN

  SELECT

  inventory_item_id

  IN

  ln_item_id

  Of

  dummy_lot_tab

  WHERE

  lot_number = p_lot_number_list (indx1); - > how direct the item here?

  EXCEPTION

  WHILE OTHERS THEN

  ln_item_id: = NULL;

  END;

  Records are PL/SQL objects.  They are not the SQL objects.  You can create a SQL TYPE (schema level) as a collection (variable-tables only, tables nested).

  So therefore your first statement is syntactically incorrect

  CREATE OR REPLACE TYPE TEST_VALIDATION_REC IS RECORD
  (order_num VARCHAR2(30),
  inventory_item_id NUMBER,
  reserved_YN VARCHAR2(1),
  error_flag VARCHAR2(1),
  Error_message VARCHAR2(2000)
  );
  

  You must put in an anonymous PL/SQL block or the stored procedure

  DECLARE
  
     TYPE test_validation_rec IS RECORD
     (
      order_num VARCHAR2(30),
      inventory_item_id NUMBER,
      reserved_YN VARCHAR2(1),
      error_flag VARCHAR2(1),
      error_message VARCHAR2(2000)
     );
  
     TYPE vald_tbl iS VARRAY(10000) OF test_validation_rec;
  
     lv_tbl vald_tbl;
  
  BEGIN
  
     lv_tbl := vald_tbl();
    -- insert your code here 
  
  END;
