• 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

  How can I get the counts for each parent in a single query
  
  Published by: user7955917 on August 24, 2012 07:26

  Generic function how you want the query to be.

  If the structure is known in advance, as in your example a 'books' and then a 'library' root element, it's as simple as:

  SQL> select x1.parent_id, x2.child_name, count(*)
    2  from tmp_xml t
    3     , xmltable(
    4         '/books/bookstore'
    5         passing t.object_value
    6         columns parent_id   for ordinality
    7               , child_list  xmltype path '*'
    8       ) x1
    9     , xmltable(
   10         '/*'
   11         passing x1.child_list
   12         columns child_name varchar2(30) path 'name()'
   13       ) x2
   14  group by x1.parent_id, x2.child_name
   15  order by x1.parent_id, x2.child_name
   16  ;
  
   PARENT_ID CHILD_NAME                       COUNT(*)
  ---------- ------------------------------ ----------
           1 book1                                   2
           1 book2                                   1
           1 book4                                   1
           2 bookn                                   1
           2 bookn_1                                 1
           2 book1                                   1
           2 book2                                   1
           2 book3                                   2
           3 book1                                   1
           3 book2                                   1
  
  10 rows selected
   
  

  If you want a generic solution that works without knowledge of the structure, you will need a recursive approach, and most importantly, you should know which nodes in distinct, I suppose that the leafs?

  Also, please help if you can provide the link of reference on the function name() years what are the other expression, that I can use after the path

  You can start reading the documentation: http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb_xquery.htm#CBAGCBGJ

  The clause PATH expects a XQuery expression however before 11.2, we can put only simple XPath expressions.

• A torn my sticker with the serial number. How to find the number of the whole installation?

  Best regards, tore my sticker with the serial number. I don't see the numbers. How to find the number of the whole installation?

  Original title: windows 7 sn

  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.

  I want to use the exact same color blue as a background color of hover for my text boxes on the form.
  
  I tried to look under:

  then selected 15 theme: Light Blue. But in the edit page for "Sidebar region, Alternative 1", in the setting area model there is none listed color.»
  
  There is only this code provided:

  Thank you for your help,

  Maggie,

  You need to spend to develop w/Firebug for Firefox. Using Firebug you can click "inspect" and move the mouse over the page to find the item you want. Once you click on the element you can see all the styles are applied, including the exact colors.
