              }

                 trace('stream received', event.name, event.streamDescriptor.groupName, event.streamDescriptor.streamPublisherID);
              }
  

  And STREAM_RECEIVE called when another user starts to appear, but the event a groupName = null and streamPublisherID is NULL too.
  I need it to give the possibility to choose the flows required to play and more low bandwidth.

  You can do something wrong. You can send me a code test and where you found null so that I can run on my sides and point of any error or debug inside.

  KeyCode is a bit model, if you use "is" to compare you won't get accurate results, you should use the operator '& '.

• 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);

  DRAW EACH BALL FALLING OUT OF THE SCREEN

  function _onEnterFrame (aEvent: Event): void {}

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

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

  _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.

• How to detect the direction of the mouse and change of scenery?

  Hello

  I'm building a single 360 degree rotation effect using individual images and buttons front and back . I am new to AS3 and have managed to create functioning buttons... (so my code can be a little weird!)

  But now, I would also like to advance frames by clicking and dragging on the image itself (or on an invisible button sitting on top of the image).

  Although there are some threads here that have asked the same thing, I don't understand how they were answered. My code is below, and the file with that I'm practicing is located on:

  https://download.yousendit.com/MVNjeFlWSWh6NE4zZUE9PQ

  Currently if you click on the area of the image, it will move forward, but there is no code to detect the direction of the mouse, he'll just before. Can someone help me understand how to set up a simple direction detection and then use it to decide whether to move forward or backward... Thank you!!

  Stop();

  move forward 1 frame on click

  function forward(e:MouseEvent):void {}

  If (currentFrame == 15) {}

  gotoAndStop (1);

  { } else {}

  gotoAndStop (currentFrame + 1);

  }

  }

  go back 1 frame during the click on

  function back(e:MouseEvent):void {}

  If (currentFrame == 1) {}

  gotoAndStop (15);

  { } else {}

  Stop (currentFrame - 1);

  }

  }

  btn_fwd.addEventListener (MouseEvent.CLICK, forward);

  btn_bck.addEventListener (MouseEvent.CLICK, return);

  change frame on direction of mouse?

  function MouseMove(event:MouseEvent):void {}

  {

  if(event.buttonDown==true)

  If (currentFrame == 15) { }

  gotoAndStop (1);

  }else{

  gotoAndStop(currentFrame + 1);

  }

  }

  }

  
  

  stage_btn.addEventListener (MouseEvent.MOUSE_MOVE, MouseMove);

• 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

  Thank you

• How to detect the event mouseclick-control

  I am trying to relax the max property Z on the scale of a graph of intensity to be changed from the front panel.  In the VI attached, I use an increment/decrement control and just detect a value change event (without taking into account the value of the control).  It works very well, even if it's a bit of a hack.

  I want to make them much more functional.  My main question is this: How can I detect an event 'control-click '?  I intend to use this event to change the max of graphic intensity by a factor rather than an additive value.

  A second quick question: on the numerical control, is there a way I can get rid of the number in the display space and leave only the increment/decrement buttons?

  Thank you

  Allan

  Are you talking about the button increase/decrease on a digital control?  I thought you had Boolean separate to increment and decrement. It's hard.  You can't be the PlatMods when using a value change event.  You will maybe make your own controls inc/dec and update a digital indicator rather than use a digital command.
