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

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.

How to find the serial number adobe Installation section
How to find the serial number adobe Installation section
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.
the desktop application gives you access to the cs6, cc, cc 2014 and cc 2015 apps. and probably more in the future.
If you already have the cc desktop application and you need to update your adobe id, log out and then back to your client application using the adobe id to pay for your subscription in cc: http://helpx.adobe.com/creative-cloud/kb/sign-in-out-creative-cloud-desktop-app.html

How to find the age of a child and snapshot number snapshot for a virtual machine.
Hi all
How to find the age of a snapshot for a virtual machine child count and snapshot.
This code snippet should help... Assuming that you have the following entries:
VM (VC:VirtualMachine)
snapshot (VC:VirtualMachineSnapshot)
System.log("====== Snapshot details for VM: "+snapshot.config.name+" ======"); var snapshotTrees = vm.snapshot.rootSnapshotList; System.log("Snapshot Tree Count: "+snapshotTrees.length); for each (snapshotTree in snapshotTrees){ showSnapshotInfo(snapshotTree, snapshot); } function showSnapshotInfo(snapshotTree, selectedSnapshot){ if(selectedSnapshot == snapshotTree.snapshot){ System.log("===================="); System.log("Name: "+snapshotTree.name); System.log("Id: "+snapshotTree.id); System.log("Description: "+snapshotTree.description); System.log("createTime: "+snapshotTree.createTime); System.log("quiesced: "+snapshotTree.quiesced); System.log("replaySupported: "+snapshotTree.replaySupported); System.log("backupManifest: "+snapshotTree.backupManifest); System.log("snapshot id: "+snapshotTree.snapshot.id); System.log("state: "+snapshotTree.state.value); var childSnapshotList = snapshotTree.childSnapshotList; if(childSnapshotList != null){ System.log("childSnapshotList length: "+snapshotTree.childSnapshotList.length); } System.log(""); } if(snapshotTree.childSnapshotList != null){ System.log("Children found: "+snapshotTree.childSnapshotList.length); for each (childSnapshotTree in snapshotTree.childSnapshotList){ showSnapshotInfo(childSnapshotTree, selectedSnapshot); } } }

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?
Tips:. 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"
-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:
Thought...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;
We will share!
Thanks in advance,
Philips

formatting of code and hierarchy for readbilityHave you looked to see if there is a cycle in the graph of dependence? Is there a table that has a foreign key to B and B has a back of A foreign key?

If you have a cycle, you have some problems.
(1) it is a NOCYCLE keyword does not cause the error, but that probably requires an Oracle version which is not so far off support. I don't think it was available at the time 9.2 but I don't have anything old enough to test on
SQL> ed Wrote file afiedt.buf 1 select level lvl, 2 child_table_name, 3 sys_connect_by_path( child_table_name, '/' ) path 4 from (select parent.table_name parent_table_name, 5 parent.constraint_name parent_constraint_name, 6 child.table_name child_table_name, 7 child.constraint_name child_constraint_name 8 from user_constraints parent, 9 user_constraints child 10 where child.constraint_type = 'R' 11 and parent.constraint_type = 'P' 12 and child.r_constraint_name = parent.constraint_name 13 union all 14 select null, 15 null, 16 table_name, 17 constraint_name 18 from user_constraints 19 where constraint_type = 'P') 20 start with child_table_name = 'MY_EMP' 21* connect by nocycle prior child_table_name = parent_table_name SQL> / LVL CHILD_TABLE_NAME PATH ---------- ------------------------------ -------------------- 1 MY_EMP /MY_EMP 2 MY_MGR /MY_EMP/MY_MGR 1 MY_EMP /MY_EMP 2 MY_MGR /MY_EMP/MY_MGR
(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 constraintsThis 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:
