• 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

• 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.

• How to control the number of fields in the Advanced mode in < af:query >

  Hello
  
  How to control the number of fields in the Advanced mode in < af:query >?
  
  Say I have 20 fields in my table, and I created a view of criteria with 2 fields. This would work perfectly in basic mode. But in Advanced mode , the choice of fields is possible by clicking on the Add fields button. I didn't have the customer to search with all 20 fields. Only 10 fields must be listed in the Advanced Mode, even if there are 20 fields in my table.
  
  How can I control the list of fields in ADDFields button?
  
  Any ideas?
  
  
  
  KR

  You can uncheck the contestable ownership of attributes that you must not appear in the Advanced Mode (but they will not appear in the other modes too!) or by programming the value the same as those mentioned here.

  Also, you can hide the button AddFields as suggested here - http://www.notjustjava.com/2011/12/cool-tips-to-showhide-components-of-the-query-control-of-adf/

• How dynamically update the role of oracle using the trigger

  How dynamically update the role of oracle using the trigger:
  
  I have svmanger owner of schema in the database. There are five tables belonged to svmanager.
  
  Table A, B, C, D, E.
  
  I have a role that is played only to these tables under the scheme: SVMANAGER_READ_ONLY
  
  now, if I create a new table F under svmanager. the role that svmanager_read_only does not work is updated, so the user had assigned role cannot access table F.
  
  is there a way to create the trigger for this role dynamically update any when a table is created or deleted?
  
  Thank you.

  I really really really don't suggest to do this - it's a bad habit. If possible I'd just adding the grant as part of the steps to the role on the new creation of the table.
  But for fun here's how you can accomplish this:

  create or replace procedure execute_grant(v_ddl in varchar2)
  is
  begin
     execute immediate v_ddl;
  end;
  /
  

  create or replace trigger catch_create_table_trg after create on schema
  DECLARE
  
  ddl_job number;
  ddl_str varchar2(50);
  begin
     IF ora_dict_obj_type = 'TABLE' THEN
  
         ddl_str := 'GRANT SELECT ON '||ora_dict_obj_owner||'.'||ora_dict_obj_name||' TO SVMANAGER_READ_ONLY';
  
         dbms_job.submit(job => ddl_job,
         what => 'execute_grant(''' || ddl_str || ''');',
         next_date => sysdate+(5/24/60/60));
  
     END IF;
  end;
  /
  

  Test it

  create table F (id number(1));
  

  Validate

  select * from ROLE_TAB_PRIVS where ROLE = 'SVMANAGER_READ_ONLY';

• How to detect the number of created quickobjects

  How to detect the number of quickobjects created? quickobject are quickbox2d.

  Basically, I have a timer that will countdown to 4 seconds and it will create a falling ball, it will get removed when she falls down. However, I want only there so that if more than 5 bullets are in step, it will cease to create until it is less than 5 to start creating some balls again. Is there a way I can do?

  It's the timer to create the ball

  If (! _ballCreation_timer) {}

  _ballCreation_timer = new timer (4000);

  _ballCreation_timer.addEventListener (TimerEvent.TIMER, _onBallCreationTimer);

  }

  _ballCreation_timer. Start();

  Function which create the ball based on clock

  function _onBallCreationTimer (e:TimerEvent): void {}

  _doCreateNewBall();

  }

  function _doCreateNewBall() {}

  _ball_quickobject = sim.addCircle ({x: PHYSICS_SCALE * (960), y: PHYSICS_SCALE * (10), RADIUS: 0.5, draggable: false});

  MAKE A LIST OF BALLS

  _balls_array.push (_ball_quickobject);

  }

  This is the part where if the table (QuickObject) ball falls down and are destroyed

  addEventListener (Event.ENTER_FRAME, _onEnterFrame);

  DRAW EACH BALL FALLING OUT OF THE SCREEN

  function _onEnterFrame (aEvent: Event): void {}

  for each (var quickObject: QuickObject in _balls_array) {}

  BALL FALLING OUT OF THE SCREEN?

  If (quickObject.y / PHYSICS_SCALE > 1080) {}

  _doHandleBallOffScreen (quickObject);

  }

  }

  }

  DESTROY THE BALL FALL OFF THE SCREEN IF

  function _doHandleBallOffScreen (aQuickObject: QuickObject): void {}

  DESTROY THE OBJECT

  aQuickObject.destroy ();

  REMOVE FROM THE CUSTOM TABLE

  _balls_array.splice (_balls_array.indexOf (aQuickObject), 1);

  }

  check the length of _balls_array.  If it is greater than 5, do not create another bullet:

  If (! _ballCreation_timer) {}

  _ballCreation_timer = new timer (4000);

  _ballCreation_timer.addEventListener (IMER TimerEvent.T, _onBallCreationTimer);

  }

  _ballCreation_timer. Start();

  Function which create the ball based on clock

  function _onBallCreationTimer (e:TimerEvent): void {}

  _doCreateNewBall();

  }

  function _doCreateNewBall() {}

  If (_balls_array.length<>

  _ball_quickobject = sim.addCircle ({x: PHYSICS_SCALE * (960), y: PHYSICS_SCALE * (10), RADIUS: 0.5, draggable: false});

  MAKE A LIST OF BALLS

  _balls_array.push (_ball_quickobject);

  }

  }

  This is the part where if the table (QuickObject) ball falls down and are destroyed

  addEventListener (Event.ENTER_FRAME, _onEnterFrame);

• How to control the number of lines of text below the image in the slideshow module?

  Lightroom 3.3

  How to control the number of lines of text below the image in the slideshow module?  I have an image with 36 words in the caption field which exports like two lines GOOD.!  I have another image with 57 words in the field of legend who runs the page and shows only a VERY BAD line.  With 57 words I can't do the single-line text box small enough to keep the text does not spread out of the page.

  Ideas?

  On the Mac platform and I expect similar under Windows, just hit enter or return key will not help. Instead, you will have to hit the keys Ctrl + Enter or Ctrl + return. This forces a new line. Windows may use a different modifier key. The screenshot below shows that it is possible. Unfortunately, you need to add the text via the caption or Description field in the library module.
