• Closure of a state machine in queue event with several parallel loops

  I am trying to find the best way to stop a program that consists of an architecture of State machine in line waiting for event with several parallel loops. Can anyone recommend the best way to achieve this in my attached VI? (To browse the forum, this seems to be a frequently asked question, but I have not found a solution that works for me.)

  I look forward to any comments on my as well code, if someone is willing to offer it.

  My program needs:

  If the user press the 'Stop' button, the program should prompt the user with "are you sure you want to stop the program?" and then return to a State of rest or move forward to stop the program. In addition if there is an error, the program should prompt the user to ' clear the error and continue, or stop the program. Then back to the idle state or move forward to stop the program.

  Architectural details:

  The program consists of 3 parallel loops: (1) a loop of event management that places different States of a queue of the State, (2) a State Machine that enters the State that is removed from the queue of the State and (3) a loop error/Shutdown, which deals with errors in the error queue management.

  During normal shutdown, where running handling loop in the case of event 'Program.Shutdown' and 'Shutdown' and the 'Idle' States are added to the queue of the State. In the state machine, the State of 'Stop' is invoked. Special "5000" error code is added to the queue of the error. In the loop of error handling and stopping, "5000" error triggered a prompt that asks the user if they want to stop the program. If the user chooses not to stop, a notifier StopNotif is sent to the State of 'Stop' and 'Program.Shutdown' event case with notification 'Go '. If the user decides to stop, the Notifier sends the notification "Stop". Loop and event management State Machine ends when they receive the notification "Stop".

  In case of error, the program behaves in the same way: If the user chooses to clear the error and continue, the program returns to the status "pending".

  HOWEVER - if the user chooses to stop the program, the program crashes. The author of the notification that is sent to stop the loop of events and State Machine management cannot be read because event Program.Shutdown and the stop State (which contain the function "Waiting to notify") are not active.

  I was able to activate the stop State by Queuing in the loop of error/Shutdown management. But I don't know how to activate the "Program.Shutdown" event by program and thus access the function "Waiting to notify" inside.

  I tried to put the function "Waiting to notify" outside the structure of the event, so the event-handling loop never ends. Placing timeouts on the "wait for declaring" and the structure of the event makes the programme of work, but I want to avoid using timeouts because I don't want to turn my event program into a program of polling stations. I would also avoid using variables or nodes property to stop loops, because that requires the creation of a control/indicator for something that the user does not need to interact with.

  Thank you!

  First of all, close the notifier outside loops with your queues.  Second, you must use a user event to send the message to the event structure loop so that it stop in the case of the stop on an error.

• Helps the state machine

  Hello everyine,.

  I'm working on a state machine. I saw a few videos of the same thing and I need help.

  I have attached the code below.

  My problem is that I can not jump since the first case at the last.

  After the execution of the first case I want LabVIEW to check fot the Boolean control attached to the function select. I used an operator oux during the operation. If the condition of "TERMINATE" is satisfied that I want him to be the last case of local variable is used to turn off the START light.

  at the moment I can't go to the latter case. I want the code to keep control of the State, and whenever the user presses the button END the LED should turn off little matter the time of execution.

  PL suggest ways to accomplish a task... am still a beginner

  Concerning

  Jalashwa

  Hi Sindhurakshak,

  You are welcome. I think that the problem still resides on the Structure of the event to the State "WBS". I can suggest the following (say that everything always ends by WBS what I understand of your current code):

  Remove select it and create a new case event for Boolean switch «end». Location of the enum to cancel in this case, as shown below:
  
  The above change means that if the value of "end" Boolean switch is changed (assuming that this will change to true), the case of the event will be held event 'end', which will then the enum value 'End' to the transition of change. Let's say that if the Boolean key 'end' has not changed (which means that has not been pressed), it should run the rest as shown below:
  

  

  

  I'll leave the enum value 'WBS' in the time-out period, assuming you want the State to always run the "WBS" idle state, unless you press the key 'end' to trigger the transition "Terminate".

  It may be useful

• queue and notifying with state machine

  I'm trying to implement a declarant and a queue to collect data that is running on a state machine in two separate loops.  I'm new to the whole and methods notifier queue and I think I'm really close to make it work as I want.  When I start the computer the first time that State everything works and it is what I expected.  When I try to restart the test and do it again she acts like the queue has been cleared and it will not connect anything to the queue.  I use the queue as a buffer for the data collected between iterations of the loop of State machine.  I empty the queue and add all the data in a table.  The declarer seems to work in all situations as I want.  I have attached a simplified version of what I'm trying to do.  Any ideas? Thank you.

  After the execution of your code (I had to make my own custom control to the States because you include not yours) and some survey values, here's the conclusion that I came to:

  It is not your queue.

  It's your math.

  In your upper loop, put sensors on the values you use to trigger the 'True' case (specifically, put a probe on the values to enter your service "superior or equal to") and then watch their values that you run your code.  The value that is coming through the shift register is your problem.  He isn't getting back to zero when you restart the test.  The first time you run your program, the value is zero.  For subsequent iterations, it's everything the last calculated deflection was.  Run your button 'force' down to zero once your test is over and look at what this value.

  Thus, when you restart your test without having to restart your program, you start with a nonzero value for calculated arrow.  Is to prevent your delta never exceed 0.001 in., and therefore your 'Real' case never executes.  So nothing ever shows in your queue.  You do not put anything in your queue.

  The reason why you go to your "complete" State in the lower loop when you hit 0.3 in flexion is because the current value of the 'deviation' is passed through your Notifier and is not dependent on the previous value of the way your queue is.  So you can always hit deflection 0.3 in., without calculated being greater than 0.001 in. delta.

  Try to reset this registry offset value in your greater than zero loop every time that you restart the test, and your program will probably work.

• help with a simple user interface for video flv with benchmarks AND buttons

  Hi all

  OK, I built a very simple FlashDrive using the componet video and I used in the flv file cue points, then I used simple buttons and findcuepoints code snipets for make my buttons go to a certain part of the movie.

  Everything works very well.

  Now what I do is when a certain amount of point play button stay an overstate and once made part of the video or another button is clicked on the first North of the State and the new part back button or the new button have the overstate.

  I think it will be an easy task, I'm not sure how to in this regard.

  Any help greatly appricaited.

  code below

  start_btn.addEventListener(MouseEvent.CLICK, fl_ClickToSeekToCuePoint);
  
  function fl_ClickToSeekToCuePoint(event:MouseEvent):void
  {
      var cuePointInstance:Object = vid.findCuePoint("ch1");
      vid.seek(cuePointInstance.time);
  }

  {
      var cuePointInstance:Object = vid.findCuePoint("ch6");
      vid.seek(cuePointInstance.time);
  }
  

  I try to help, but you will need to apply your neurons to make it work with what I have already explained (three times with what I propose below).  Try something like the following (I'm rename your buttons for ch1, ch2, ch3, ch4, ch5 and ch6 so that the same functions can be shared by all the buttons...)

  This affects the listeners to all 6 buttons

  for (var i: uint = 1; i<7;>

  This ["ch" + String (i)] .addEventListener (MouseEvent.CLICK, fl_ClickToSeekToCuePoint);

  }

  It deals with one of the 6 inclinometer when they are clicked

  function fl_ClickToSeekToCuePoint_1(event:MouseEvent):void

  {

  BTN var = event.currentTarget;

  var cuePointInstance:Object = vid.findCuePoint (btn.name);

  VID. Seek (cuePointInstance.Time);

  resetButtons();    What makes all the buttons back to normal

  btn.upState = btn.overState; What makes the States of change of the button clicked

  }

  function resetButtons (): void {}

  for (var i: uint = 1; i<7;>

  This ["ch" + String (i)] .upState = this ["ch" + String (i)] .hitTestState;

  }

  }

  To do this, your buttons need to have the same work as part of hit as they do under the top.

• Help with Time Machine

  Although I've owned a mac for years, I started using Time Machine a few months ago only.

  For two weeks, I said that my backup disk was full. Today, I got the message that the backup failed and that yesterday was the most recent upward. a double click on the backup disk, I see the records dating back to November. However, when I get Time machine, I can only highlight yesterday.

  So, a few questions.

  1. the November record is really an existing back-up? Why do I see there, but not in Time Machine?

  2. I have several external hard drives that I use for Time Machine and I am interested in finding someone to help me with the best solution to achieve my goal. That is, to remove the 300 GB of photos I have on my internal hard drive to an external hard drive, while still supporting upward from my internal hard drive and a multimedia hard drive for Time Machine.

  I hope I can say this is not confusing.

  I have an internal 500 GB running 10.11.1 HD because I have pictures of some 300 GB internal hard disk, I only 6.66 GB of available space.

  I have 3 external drives available that I can use for the back upward. 1 TB, I got for Christmas and is not used for anything and 2 500 GB HDs... one of them is currently used for Time Machine. The other has a backup is no longer necessary, so I can be erased.

  In addition to using Time Machine to back up, I also pay a monthly fee for Crash Plan. Even though this was my home folder files, it does not back up the operating system. I can, however, point it to back up an external hard drive.

  Finally, these are my questions. To free up space on my internal hard drive, can I (should) move the photos off my internal HD (I don't use iphoto) and put them on an external HD and then have my internal HD and HD with photos backed up with TM? Would it not be better to transfer my photos on a 500 GB HD and then use the 1 TB (without this partitioning) to back up both the internal and external HDs?

  I hope that what I am asking is logical. Thanks to all those who want to take part of my ramblings and give a meaning to me.

  Respectfully,.

  Cayleen

  What I do with my Mac sounds a bit like what you ask to do with yours. I have:

  -Photos and movies on an external drive (500 GB on a 2 TB disk)

  -The rest of my data on the drive internal (approximately 300 GB on a 1 TB drive

  -The internal and external are saved on a third drive (3 TB) used for Time Machine.

  Everything works very well.

• Help with the MOUSE_OVER and MOUSE_OUT events

  Hello

  I am very new to Flash and I'm having a bit of a problem with my first ActionScript.

  I'm working on a project where I have a black and white photo. When you hover over the image, it turns to a color version of the same image. When you take your mouse out of the picture, it was in black and white.

  I have three instances of the image, a black and white image to frame 1, a color to frame 10 image and a black and white image to frame 20. Currently, when I mouse over the black and white photo, it turns to color image as I had hoped. However, when my mouse leaves the image, she remains on the color image.

  My code looks like this:

  import flash.events.MouseEvent;

  Stop();

  btnCory.addEventListener (MouseEvent.MOUSE_OVER, coryOn);
  btnCory2.addEventListener (MouseEvent.MOUSE_OUT, coryOff);
  function coryOn(event:MouseEvent):void {}
  gotoAndStop (10)
  }
  function coryOff(event:MouseEvent):void {}
  gotoAndStop (20)
  }

  btnCory is the first black and white photo in frame 1, btnCory2 is the frame of 10 color picture.

  Any comments / help would be much appreciated.

  
  Thank you

  
  Jeremy

  your movieclip with images on frame 1, 10 and 20 must have a name (for example, image_mc) and you do not need to convert images on 1 and 10 executives (and 20 if there is no point to have a duplicate on frames 1 and 20 image) to objects and your code should look like:

  import flash.events.MouseEvent;

  Stop();

  image_mc.addEventListener (MouseEvent.MOUSE_OVER, NFB);
  image_mc.addEventListener (MouseEvent.MOUSE_OUT, offF);
  function onF(event:MouseEvent):void {}
  image_mc.gotoAndStop (10)
  }
  function offF(event:MouseEvent):void {}
  image_mc.gotoAndStop (1);
  }

  and a message in the cc forum I see you are using 5 images, so use:

  import flash.events.MouseEvent;

  Stop();

  image_mc.addEventListener (MouseEvent.MOUSE_OVER, NFB);
  image_mc.addEventListener (MouseEvent.MOUSE_OUT, offF);
  function onF(event:MouseEvent):void {}
  MovieClip (e.currentTarget) .gotoAndStop (10)
  }
  function offF(event:MouseEvent):void {}
  MovieClip (e.currentTarget) .gotoAndStop (1);
  }

• Need help with the earpiece of video events complete and twinkle in Web site button

  Hello.

  I'm building my first site flash on AS3 and I'm having some problems that I can't solve.

  Question No. 1:

  I have a video that plays on a page (frame) and want to go to the next page after the video is finished. It's pretty easy... I did a search for information and came to the top with something in the sense of (written in memory):

  instance.addEventListener (Event.COMPLETE, instancecomplete);

  
  function instancecomplete(event:Event):void {}

  gotoAndStop (3)
  }

  And it worked fine when the page loaded initially (it was the homepage), but after he moved to the next page, I clicked the button which takes back me to the homepage and what might happen is that the video would play for about 1 second and send me back to the next page. My assumption is that what is happening is in loading, the event listener is to see that the video does not play, assuming that it is finished, and it takes me to the next page. If this is true, is there a way to delay the eventlistener?

  Question 2:

  The buttons on my page of sparkle. I read on this topic, and I apparently it's because I'm on a mac. I checked on a PC and the flicker isn't here so it must be because im on a mac. On a forum I found the following line to fix it:

  btnHome_mc.buttonMode = true;

  The problem is... I never wrote this line, and if it is a code generated automatically, I can't find it in the scripts of action... so I'm stumped. Any help?

  I don't know what to say without seeing the code.

  Try to remove the listener:

  function onComplete(e:VideoEvent):void {}

  instance.removeEventListener (VideoEvent.COMPLETE, onComplete);

  }

• Lost newbie, need help with dream machine construction

  Hi all!
  I was wondering if you could tell me what you think this configuration for first, after effects and use of speed category:

  http://pcpartpicker.com/user/Trundrumbalind/saved/#savedbuild_167634

  
  I know this is probably an overdose, but whatever you think?

  First of all, I would not go for this card its particular discrete: is not enough better than audio shipped to justify the cost of $58. In addition, this card is not a real X - Fi card; in fact, it's basically a descendant of the old software Ensoniq AudioPCI, what (mis) uses the CPU for most of the audio work (there is a controller on the card chip, but this chip is very similar to the audio embedded codec-based).

  Second, the RAM and the motherboard are exaggerated both. In fact, you might not be able to run all four sticks of RAM to anywhere near its speed of DDR3-2133. Intel (and JEDEC) officially limit the speed of maximum memory with a memory controller fully powered only speed of DDR3-1333. You can run this memory to DDR3-2133 speed using a profile XMP - but then, you are limited to running only two sticks of RAM at this speed total. In addition, this four-channel kit is really intended for platforms LGA 2011, not platforms LGA 1155. And the motherboard is actually that much money as or more than money that many motherboards X 79 LGA 2011. Don't forget, the LGA 1155 platform has only two channels controller memory, not four. Official JEDEC specifications allows the implementation of four ranks per channel of memory - controller but in only up to the speed of DDR3-1333. With RAM-DDR3-1600 and high speed as well as all the RAM running using XMP, JEDEC profiles limited officially this operation to only two ranks per channel (one DIMM two-face, as in all 8 GB DIMMS, already devours two rows per slot).

  In other words, that the installation is a waste of money at this price. Why spend $2600 + on a generation of LGA 1155 limited when you could have gotten a higher performance LGA 2011 build with an i7 - 3930 K for the same price or a little less? In fact, I personally not spend more than about $2,000 for LGA 1155.

• Need help with the events of user base in state machine example in queue

  I wrote a small example queue state machine to try to teach myself about the creation and use of the user events.  The purpose of the machine is periodically pick a number (I do now with a control instead of a generator of random numbers for troubleshooting), and compare this figure with the number I put in a control.  When they match, I want to raise an event to fire so I can do something about having found a match.  The examples in the file LV references help show events within the structure of the event, but I want to reach out of a State and trigger an event...

  Can someone point me in the right direction here?

  I think the service you're looking for is generating the user event.  What to put in your consumer loop, inside the case structure when identical numbers.

• State machine with the help of event

  Hello everyone,

  I have a question on how to achieve the "Timeout". In the diagram below, you can see 2 different situation:

  1. in the 1st case, I used the state machine, it starts in State 1, that contains a case of event. From there, it will first be determined, if the input value has changed in 10 seconds, if it didn't, the state machine will go to State 2, if it is changed, will also be determined, if the value equal to 3, if so, input the distributor of State will in State 3, if not, go back to the State 1. (this VI I've done it before, you can take a look at the attachment).

  2. my question is in the 2nd case. He also started the State 1. Here, the input value can also be changed (once or several times) or not. If the value has not changed within 10 s, or even if it's been changed many times within 10 seconds, but it was never equal to 3, the state machine will go to State 2. only when the value of the entry within 10 seconds equal to 3, he can jump to State 3.

  This problem, I do not know how to solve, everyone has no idea or improve methods?

  Thank you very much!!

  

  My bad, dint tested before posting (in addition to kills confidence)...!

  Let me know, if it works this time...!

• Help with Machines at State

  I implement my application using state machines, and I have the following problem.

  1. I have an initialized state that initialize my controls.

  2. then, I want the next State to check user input. (Boolean button will be be supported to determine what state is planned).

  3. in one of the States, I want the user to be able to change the values initialized and then return to the State of user input, in order to determine what state is expected

  I put in place the initialization state, but also the State of user input (use event structure for this report), but I don't know how to let the user may change the values of my control, the user acknowledges the change then the State goes back to the State of waiting for the next state user input.

  Thanks for any help

  Your user input is also what I would call an idle state.  If nothing happens, it just goes back to itself.  (Put some statement waiting there so that the idle state is not acting as a "greedy loop".)  If change is found, then instead of the called resting State, the initialization state is called again.  The initialization state is running and when it's done it goes back to idle input state.

• Need help with user events

  I have an initialize VI where I create a number of user events.  Originally, these consisting of a number of different types of data and have been released as a cluster.  However, I had to change this to an array of variant, as I'm indexing later user refnums in a loop FOR to generate a Boolean matrix of the conditions-based events.  As I'm unable to elements of a cluster index, I have all types of event data changed to variants so that I could pass them on in a table that could be indexed.  It seems, however, that the labels property that populate the structure of the event with the names of the individual event to select from are lost during the use of variants - the structure of the event shows that multiple instances of

  : User event

  in the drop-down list.  Is it possible to get the event names to persist or pass them in the structure of the event, so I can configure cases properly?

  It seems so the VI changed with the data types variant event works, but for some reason, the structure of the event did not update to reflect the changes.  After removing and recreating the event record Refnum indicator in my VI initialization and recharge the parent VI, everything seems to work as expected.

• Structure of the event in a state machine

  Hi all

  I have a state machine with a sort of stand-by, where a user can select the next button state. I tried using a structure of the event with changing the values to select the next case, but when the state machine is in a specific case and the button of another State on the blocks of all things. I've attached an example, the lights simply stating that you are in the State.

  Thx for your time,

  Edit: actually, I miss-clicked

  1. you have not need a while loop around the structure of your event.  With no wired time-out, you will never get a timeout event.

  2. your button events are set to 'Lock Front Panel until end of the event'.  Uncheck the box which.
