• How to detect the data type is?

  Hello!

  I built a function of VI. But I want to make it safe - function could detect what type of data is connected to the inputs and only allow certain types of data cabling. How can I do this?

  Thank you

  You could look in polymorphic VI.  They will allow you to connect different types of data.  However, it is not really an option to "do not allow" it.

  If someone creates their own s VI in LabVIEW, then they should pay attention to details like the stress points.  Other than provide good documentation describing the function, inputs and outputs of a Subvi, it's not really necessary for the creator of the Subvi to prevent another programmer to use this Subvi wrongly.

• How to detect the key ALT pressed in os7

  Hai,

  How to detect the key ALT pressed in Os7...

  Can I use the source for os 7 as below? ,

  protected boolean keyStatus (int keycode final, time final int) {}

  If (Keypad.key (keycode) == Keypad.KEY_ALT) {}

  ...

  Returns true;

• 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);

  }

• How to detect the color pages in a PDF file?

  I use a plug-in of Acrobat C++ read/modify a PDF file.

  I need to get the total number of pages in the PDF file and the page numbers of the pages in color.

  So far, I was able to get the total number of pages using PDDocGetNumPages() with no problems.

  However, I can't find an API that lets me know if a particular page is color or not. Is there a way to do this?

  Thanks in advance!

  But what happens if there are RGB data which means black or grey (R == G == B), that means black or RGB?

  There is a code sample in the SDK to browse content in the PDF file, and then you can get the color space and color of each object.

  But you really need to do background research on the colors & spaces to achieve this properly.

• How to get the SQL if I get exception

  I get this exception and do not know what was the actual sql with the variables of liaison who was executed.
  
  
  
  sqlmesg = error in the select query to retrieve the segment associated with a pair of cables: ORA-01006: there is no bind variable
  
  y at - it a way to get the real sql executed so I know what mistake I did.

  I thought your question was about how to view the SQL statement and bind variables in the exception. The answer to that is to put variables in the exception message.

  The root cause of the problem seems to be that your dynamic SQL statement may require 3 or4 variable bind but your USING clause specifies always 4 values if the underlying SQL statement has 3 positions, it will lead to an error.

• How to escape text in the query pattern to avoid the SQL Injection

  We plan to use Oracle Text to search for in a Java web application and use a query template as shown below, but are concerned about SQL Injection attacks. In general, we use a parameter query, but that does not seem possible with these search patterns. Is there advice or recommended to avoid SQL Injection when using query patterns - what characters need to be escaped or cleaned the entry user, etc? Or is there another approach to query patterns which does the same thing, but can use the settings?
  
  Select (1) score, my_id from my_table where CONTAINS (search_dummy,
  ' < query >
  < textquery lang 'grammar' = 'CONTEXT' = > dangerous search terms
  < progress >
  < seq > < rewriting > transform ((JETONS, "${", "}","")) < / rewrite > < / next >
  < seq > < rewriting > transform ((JETONS, "${", "}",";")) < / réécrire > / suiv >))

  < / progress >
  < / textquery >
  < score datatype = "INTEGER" algorithm = "COUNT" / >
  (< / query > ', 1) > 0
  ORDER BY SCORE (1) DESC;
  
  Thanks in advance for any help or advice!

  You should be able to put the entire query to the CONTAINS clause argument in a variable binding. Prevent SQL injection. It is possible they could do 'contains the injection' and perform research of the else clause contains this as your intention, but unless you are relying on a part of contains the clause to implement security, that shouldn't be a problem.

• How to use the clause type conditionally create new lines

  This question is just for learning - no object other than to start real world to create versions of some queries known to learn how to measure the performance of the MODEL clause clause of the MODEL versions.

  The question is: How can you write a STANDARD clause that pivots (updates) ONLY the lines that actually need to rotate and do NOT change the lines that have no value and cannot be rotated.

  I found a good site that has about two dozen example articles on different pieces. This first link is the beginning of the series.

  SQL features tutorials - Clause TYPE

  http://www.sqlsnippets.com/en/topic-11663.html

  This link is to a clause of FAQ of BluShadow MODEL version "how to convert rows to columns."

  Line - MODEL method string

  http://www.sqlsnippets.com/en/topic-11987.html

  The solution to this link uses this line of source:

  POSITION KEY VAL

  --- ---------- ----------

  R08 0 v1, v2, v3,.

  and this result set:

  POSITION KEY VAL

  --- ---------- ----------

  R08 1 v1

  R08 2 v2

  R08 3 v3

  The reason why it produces that result set is this clause of the statement of MODEL

  RETURN THE UPDATED LINES

  If you comment on this article, you will see that the original lines are all in position 0. This means that the solution reproduced EACH SOURCE LINE even if there is only one item in the list of values.

  Thus, even a line source with a single value (for example, the r01 'a') will be updated and updated this line is returned.

  For a large number of data sources with only a few lines that actually need to rotate it would be a great performance of infringement.

  This is the sample data source

  with t as (button 1, 'a' value 'abc' col2, col3 'def' of the double
  Select Union all 2, 'b', 'ghi', 'jkl' from dual
  Union all select 3, 'c, d, e, 'mno', 'pqr' from dual.
  Union all select 4, 'f', 'stu', 'vwx' from dual
  )
  Select the key, value, col2, col3
  t

  KEY, VALUE, COL2, COL3
  1, a, abc, def
  2, b, GHI, jkl
  3, "c, d, e, mno, pqr.
  4, f, stu, vwx

  Lines 1, 2 and 4 only have a value of (a, b, c respectively.

  Only line 3 must rotate. It contains "c, d, e" and which must become 3 lines in the result set

  Value of the key, col2 col3
  1 an abc def
  2B ghi jkl
  3 c mno, pqr
  3 d mno, pqr
  3 e mno, pqr
  4 f stu vwx

  The nut of the problem is that if the clause 'RETURN UPDATED ROWS' is used, then the lines 1, 2 and 4 must be updated in order to be returned in the result set. And if this clause is NOT used, then line 3 must be updated by 'c', d, e 'c' and two new product lines: one line for a ' and one for 'e '.

  How can you do this with the TYPE clause without the help of the clause "Return LINES UPDATE"? I don't have a solution to sample showing what I tried because I can't understand what it takes to even try.

  I have a solution that uses "RETURN UPDATED ROWS" but I want to compare this performance to the exercise, when this clause is NOT used.

  We ask BluShadow to add the solution of MODEL clause to this FAQ with other similar solutions.

  Like this?

  SQL > with t as
  () 2
  3 select the 1 key, 'a' val, 'abc' col2, col3 'def' of the double

  
  Select 4 Union all 2, 'b', 'ghi', 'jkl' from dual

• How to filter the file type and size during uploadind files in APEX

  Hello
  
  I was wondering how I can do to validate the size of a file, before moving in my table? I want to filter the type of file, but for this one, I think I can use regular expressions in a validation process.
  
  I don't know if there is a way to read the size of the file, even before sending it into the temporary table.
  
  Thank you
  
  Bodart

  Hi salma,

  As far as I KNOW, you need to create a validation APEX (PL/SQL Returns Boolean or returns error text), which interrogate the details of the table apex_flow_files file. Here you can get the file type and size etc.

  So just to validate and if the validation fails, then delete the apex_flow_files and riase error message file.

  Kind regards
  Hari

  P.S. Please note that, if there are other validations apex on your page, and if they fail, always apex will load the file in the apex_flow_files table. It is sensible to create a validation (PL/SQL) that will trigger (condition) when online validation errors occurred. Make sure it is the LAST commit on your page in the sequence. And here you can write code to delete the table apex_flow_files.
