  I have a table with a field Champ_1 emp
  
  in this particular Champ_1 is an address column where the data can be as ' 12 st first floor"but suppose by mistake the user has entered data as 12 st first floor & ' must be restricted (not using relaxation but can this be possible using constraints) so for this we can how to restrict the special characters only not to get entered in the column.
  
  
  Kind regards

  Yes you can do it like this

  Table created.
  
  SQL> alter table t add constraint t_chk check(length(regexp_replace(field_1, '[[:alnum:]|[:space:]]'))=0);
  
  Table altered.
  
  SQL> insert into t (field_1) values ('12 st first floor');
  
  1 row created.

• 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);

  _doHandleBallOffScreen (quickObject);

• 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.

• The null characters to flatten to a string

  Hi all

  I use the flatten the string function to convert a digital picture of a data string flattened in hexadecimal. When I do that, it adds 6-character null (zeroes) before each element of the array. How can I flatten my table without the addition of these null characters?

  Thank you

  Change your data type to U8 (bytes) and a constant false to precede the wire size.

  With an array of bytes and not prefix size, you might also Type Cast

• How to detect the resource (find) information?

  Hi all

  I'm trying to detect programmatically information resource name for devices HSDIO PXI and PXI-4130.   How can I do?    System DAQmx property does not include these devices, and I can't find a way to convert a resource VISA name in name of resource HSDIO or NI DC PS formats.  I enclose a code snippet that detects resource VISA for a device 6552 name, but I can't seem to figure out how to get the name of MAX the device resource.   Both the niHsdio and the properties of 'name of the resource' OR DcPS requires that you spend a session valid in them need valid resource name andI to make...

  And no, asking the operator to launch of MAX and find the name of the resource is not an option

• How to detect the number of channels on an oscilloscope?

  I have various models sitting around the laboratory, some two-channel, a few four-channel oscilloscope.  I would like for my program to be able to detect the number of channels is available.

  I can just tell my program how much string is available based on the model number, but is there a VISA command to request scope directly what channels he has?  I would also be able to ask what, if any, ability to function math there.

  "all drivers of the oscilloscope must return the instrumentID after initialization, and that should be enough to know the number of channels.

  What Albert was referring to is that all compatible drivers IVI in their base class interface have an attribute/property that indicates how many channels has the scope.

  If you don't want to use the driver of the IVI for the scope then maybe download some of the drivers and check the source code to see how they calculate this dynamic repeated capablity.

• How to detect the cFP-1804

  Hello

  I have a cFP1804 connected to a cFP2120 via EThernet.  The cFP1804 has a thermocouple installed package that is read once per second the 2120 by using the 'FP Read.vi"(see file attachment). When systems are interconnected, the correct values of returns «FP read» When disconnecting from the cFP1804, "PS read" still will continue to serve the received values but triggers error 33800 until the connection has been restored. So far so good.

  The problem I have happens when you reset the cFP2120 while the cFP1804 is offline. At that time a single "FP read.vi' will cause the program running on the cFP2120 to stall completely.

  No idea how to get around this problem?

  Hi Volker,

  You can detect the RT and network objectives using the replication VI system. An explanation can be found in NI Developer Zone tutorial: replication of system of target in real time at http://zone.ni.com/devzone/cda/tut/p/id/3937. The download link is at the bottom of the page. Be sure to read the included Readme for installation instructions. If you run the VI find all targets, you will be able to test if the cFP-1804 is on the network.

  I also used a UI component custom named "ListStyleButtonField" come from the official web site of blackberry, once all the ListStyleButtonField of accumulated height exceeds the height of the content field, which cause the ListStyleButtonField lost her concentration and I do not know the focus was left to the last content topic whose screen slipped to finally make the time.

• How to detect the stop scrolling

  Hi all

  I am currently working with the Bold and Storm, JDE 4.6.0 and JDE 4.7.0 respectively. I have the following question: How can I detect when the user stop scrolling? I have set up a ScrollChangeListener.scrollChanged () that detects when the user begins to scroll through the screen. At the moment, I put a Boolean variable in the true, but now I need to put the same variable to false when the user stops scrolling and I don't know how to do it. Any idea?

  Is there another listener or event that it would be useful for detecting the start and stop scrolling or the movement on my screen?

  Thanks in advance for your reply,

  Gabriela.

  Try to implement a TimerTask with Timer class to check the status of scroll each time.
