How to find the number of data items in a file written with the ArryToFile function?

I wrote a table of number in 2 groups of columns in a file using LabWindows/CVI ArrayToFile... Now, if I want to read the file with the FileToArray function so how do I know the number of items in the file. during the time of writing, I know how many elements array to write. But assume that I want the file to be read at a later time, then how to find the number of items in the file, so that I can read the exact number and present it. Thank you all

Hello

I start with the second question:

bytes_read = ReadLine (file_handle, line_buffer, maximum_bytes);

the second argument is the buffer to store the characters read, so it's an array of characters; It must be large enough to hold maximum_bytes the value NULL, if char [maximum_butes + 1]

So, obviously the number of lines in your text tiles can be determined in a loop:

Open the file

lines = 0;

While (ReadLine () > 0)

{

lines ++;

}

Close the file

    Option 1:

    If the COA sticker is damaged, you must use the recovery partition to reinstall Windows 7, it will be exempt from the need to use the product key to activate your installation of Windows 7.

    Option 2:

    If your recovery partition is not available or damaged, you must contact the manufacturer of your computer, and request that a defined recovery disk you can use to reinstall Windows 7. They could practice a small shipping and handling. This will exempt the need to also use the product key.

    Option 3:

    If neither options 1 or 2 is possible, then you will need to invest in a new license of full version of detail.

    Creative cloud does not use a serial number and creative cloud subscribers for not having any serial number associated with their programs.  Creative cloud subscribers use their adobe ID to activate their programs.

    Download and install the desktop creative cloud application (after signing with your adobe - the same as that used to pay for your creative cloud subscription ID), https://creative.adobe.com/products/creative-cloud

    Open the office application (a shortcut will be on your desktop) > click applications, and then select the programs you want to install.

  • How to find the child level for each table in a relational model?

    Earthlings,

    I need your help, and I know that, "Yes, we can change." Change this thread to a question answered.

    So: How to find the child level for each table in a relational model?

    I have a database of relacional (9.2), all right?
    .
         O /* This is a child who makes N references to each of the follow N parent tables (here: three), and so on. */
        /↑\ Fks
       O"O O" <-- level 2 for first table (circle)
      /↑\ Fks
    "o"o"o" <-- level 1 for middle table (circle)
       ↑ Fk
      "º"
    Tips:
    -Each circle represents a table;
    -Red no tables have foreign key
    -the picture on the front line of tree, for example, a level 3, but when 3 becomes N? How is N? That is the question.

    I started to think about the following:

    First of all, I need to know how to take the kids:
    select distinct child.table_name child
      from all_cons_columns father
      join all_cons_columns child
     using (owner, position)
      join (select child.owner,
                   child.constraint_name fk,
                   child.table_name child,
                   child.r_constraint_name pk,
                   father.table_name father
              from all_constraints father, all_constraints child
             where child.r_owner = father.owner
               and child.r_constraint_name = father.constraint_name
               and father.constraint_type in ('P', 'U')
               and child.constraint_type = 'R'
               and child.owner = 'OWNER') aux
     using (owner)
     where child.constraint_name = aux.fk
       and child.table_name = aux.child
       and father.constraint_name = aux.pk
       and father.table_name = aux.father;
    Thought...
    We will share!

    Thanks in advance,

    (2) If you try to write on a table and all of its constraints in a file and do it in a valid order, the entire solution is probably wrong. It is impossible, for example, to generate the DDL for MY_EMP and MY_DEPT such as all instructions for a table come first, and all the instructions for the other are generated second. So even if NOCYCLE to avoid the error, you would end up with an invalid DDL script. If that's the problem, I would rethink the approach.

    -Generate the DDL for all tables without constraint
    -Can generate the DDL for all primary key constraints
    -Can generate the DDL for all unique key constraints
    -Can generate the DDL for all foreign key constraints

    This is not solidarity all the DOF for a given in the file object. But the SQL will be radically simpler writing - there will be no need to even look at the dependency graph.

    What happens if the PL/SQL table has NULL values. Question is how you want to handle NULL values. You want to ignore nulls as GROUP BY do? If you want to consider NULL values, you can say if you want to order the NULLS FIRST or NULLS LAST. I guess that logical GROUP BY:
