• How better to insert a subarray (line) in a 2D array to the correct index which is based on the value of the first column

  Hello

  I would like to insert a subarray (line) in a 2D to the correct index table. The position is to say the index value depends on the value of the first column of the table 2d.

  As an examlple my 2d array would look like this

  230 50 215 255

  300 60 270 330

  360 20 350 370

  And I would like to insert another line (subarray) with the following values

  320 40 300 340

  This new line should be placed between the second and third rows (this is based on the first column only).

  I tried the threshold 1 d function table by taking an 1Dsub array of my 2d array (first column), then using the first of the new line (320) as the threshold. It sort of work, but it does not work when I start the table (IE there is only 1 row) and it seems to not work properly on other occasions (as explained in the help of Labview).

  Hopefully the explanation is clear enough for any suggestion. Thanks in advance for the help!

  The idea is I have start with a new table and add these lines in the right order every time that the user sets the values Jack

  Ahh, so try this.

  This will also work with an empty array.

  You want to do with this function it is a Subvi.

  Make the entries 'table' and 'subarray"on the connector, then 'new array' output.

  You can then put this Subvi in a loop with a registry to shift and it will help to add new lines in a sorted order, when they are added.

  That is what you were aiming for?

• How remove the line by line by comparing to the first column?

  Hello!
  
  I have a problem - I need to remove the line by line, but the problem is, I know that the first COLUMN of the table is a PK.
  To retrieve the NAME of the COLUMN that I use:
  
  SELECT column_name, table_name FROM USER_TAB_COLUMNS WHERE column_id = 1 and table_name = c1.tmp_table_name;
  But it does not somehow.
  Below you can see my script (which has not worked for now):
  
  declare
  XXX varchar2 (100);
  Start
  C1 in (select table_name, tmp_tables tmp_table_name) loop
  IMMEDIATE EXECUTION
  ' SELECT column_name in ' | xxx | "USER_TAB_COLUMNS WHERE column_id = 1 AND table_name = ' |" ' || C1.tmp_table_name | " ' ;
  immediate execution
  "start."
  for c2 in (select * from ' | c1.tmp_table_name | start loop ')
  Insert into ' | C1.table_name | "values c2; delete from ' | C1.tmp_table_name | 'where ' | xxx |' = c2.' | xxx |'; exception: when other then null; end; end loop; end;';
  end loop;
  end;
  
  P.S. The Inserts work perfect. I have a problem with deleting lines that are in c1.table_name, of c1.tmp_table_name (the two tables have the same structure, PK, always), because I have the names of columns different another tables which are PK. (for example: K, ID, NS and so on) Please help me to write the correct script.
  For example this will be for the first line recovered as:
  Start
  C1 in (select table_name, tmp_tables tmp_table_name) loop
  immediate execution
  «Start for c2 in (select * from ' |)» C1.tmp_table_name | Start loop ')
  Insert into ' | C1.table_name | "values c2; delete from ' | C1.tmp_table_name: ' where K = c2. K; exception: when other then null; end; end loop; end;';
  end loop;
  end;
  This script works perfectly. But I have many other tables with different PK - K No.

• Read the data in the first column selected in a multicolumn listbox

  When a line is selected in a ListBox multicolumn (1 point), how can I go on reading the data in the first column?

  

  The listbox multicolumn itself is the digital picture data type. If you have allowed only 1 point selection and selection mode select any row, it returns the line number. The property node 'Element names' to return a table 2d-chains of the elements in your Inbox. The index of the row to the value of the listbox and column 0. See code attached.

• How the first column heading must be repeated if the table breaks across pages

  Hi Experts,

  Please help reslove this issue...

  Hello

  You can add the tag to the first column and the first row of the table. It will repeat 1st column when table to break across pages.

  Here 1 means, repeat first column when table to break across pages.

  I hope this will solve your problem.

  P.S. If you provide 2, this means, repeat for column 2 of the table through the pages

• Change the first column seen in the datagrid by code?

  Hello

  Is anyway to change the first column in a DataGrid using action script? I mean, for example, think I have 10 columns, only 3 are seen (0,1,2). I just want to have a button to change the first column view. Thus, for example, if I press it, 1.2, and third column will be those that is displayed in the datagrid control. I need to emulate the same thing that the scroll bar when you drag in a datagrid, but instead of letting the scroll bar does that automatically, I want to "scroll" datagrid manually.

  Moreover, is anyway through datagrid children and hide the scrollbar manually?

  Thanks in advance,

• Limit the number of characters in a text based on the first digit field

  Hello and thank you in advance for your help!

  I want to limit the amount of characters in the text field based on the first digit of the number (the text field is limited to a number format... no decimals, no comma).

  For example, if the number starts with a 3, I would limit the text field to allow only ten characters. I have three scenarios but if I could start with code and what is the best place to add (key combination or validation?) I can take it from there. Thanks again for your help!

  I wrote this code for you that does this. Use it as a typo of the custom field code:

  // Validate that only digits are entered
  if (event.change) {
      event.rc = /^\d+$/.test(event.change);
  }
  
  // Validate string length if it starts with 3
  if (/^3/.test(AFMergeChange(event))) {
      event.rc = AFMergeChange(event).length <= 10;
      if (!event.rc) app.alert("If the number starts with \"3\" it may not be longer than 10 digits.",1); // optional error message
  }
  

  You can duplicate the second part of it for additional terms, but keep in mind that this code won't let you even remove the first character in the field if the result is not valid.

  For example, if you enter "234567890123456" then you can't remove the "2" at the beginning because that would result in a number not valid. You can delete all the other numbers, even if and when it is 10 digits or less, then you can remove the departure "2" as well.
