• Stop the loops with a button

  I have an infinite loop is and display of data. How can I end the loop with a button or a keypress?

  Periodically perform a ProcessSystemEvents() call inside the loop. In a reminder of the STOP button, set a flag to indicate your loop to stop.

  stop unsigned int = 0;

  While (! stop) {}

  data getmeasured

  display the data

  ProcessSytemEvents()

  Sleep (250);   to be polite: it is impolite to spinlock, since you will monopolize the CPU and other threads can get hungry

  }

  then, in the reminder for a STOP button

  STOP the button callback routine

  stop = 1;

• How to pause and resume a while loop with a button

  Hi all!

  I'm back in LabVIEW, after only a few years and I cannot understand, what at first sight seems to be a simple problem!

  All I want to do is have a while loop in which, for the purposes of illustration, I have the 'random number from 0-1' function on the inside, and I want to be able to pause and resume this help from a button. There are a few other posts on the forum that are very similar and do use "event structures. The problem I encounter is that I can get the genarator random number to start the generation but the break will not stop this!

  I have the feeling that I made a stupid mistake - but I can't understand or google my way out the problem! I enclose my solution so far!

  See you soon!

  I did an example (you can drag and drop the image into a labview diagram > = 2014)

  hope this helps (I just did 2 excerpts, it's the same program)

  

  

• write the file wav with power button

  Hi all

  I am trying to record a wav file at a push of a button with Auto name files.

  The idea is the VI is running, display data when recording key data are saved as wav up to what the key once again. The file name is generated with the date and time automatically. The user can create as many record as he or she wants without stop the VI.

  As you can guess, I'm not a good labview programmer and I have a problem because my VI does not work properly. The return registered wav file are huge they seem to hold too much data essentially. When I play it back it sounds loop. I understand that the problem is with my VI. Believe me, I've been trying and trying without success. Could someone have a look please and let me know what the problem. I do not understand how to operate the part save my VI.

  Please find attached my VI.

  Thanks in advance for your help.

  Frédéric.

  Yes, our solutions are remarkably similar.

  Be careful to close files when you have finished writing for them - I'm not sure that you have done this. You placed a fence outside the loop that will only close the most recently created file.

• Pavilion dv6636 stuck in a reboot loop with no boot

  Hello

  I have a Pavilion dv6636 purchased on Oct / 2007 which saw a reboot loop with no boot. By pressing the Start button, I can see the hood leds on, power on (as well as the port for illuminated around blue AC adapter), HD led being turned on once and can hear the pilot DVD is powered and the fan turns, then, after about 10 seconds (while the screen is always black), he stops, remains off for 5 sec , then restarts, stuck in this loop. Experiences I've already done:
  -hard reset
  -reset of memory
  -stable memory locations
  -exchanged memories
  -started with memories (sounded a beep as expected)
  -had started with HD (continued with the same symptoms)
  -F8 or F2 keys pressed during startup (black screen and continued with the same symptoms)
  -F10 key during startup (by pressing F10, it does not shut down as usually does, but rest died, with black screen and rotation of the fan)
  -external monitor plugged in when you start (black screen and continued with the same symptoms)

  Same question occurred in about 4 months ago, but at that time, after break of a week I tried to start and has been a success. Not at the moment.

  Please, any thoughts of what could be the problem?

  Thank you

• How one does sound loops on a track to create a song?

  I am new to apple.  I would like to know how to draw loops of sound on a track?  I chose the path and the instrument, now how to record sound? in my sony software you just draw on the road to a loop selected to place it on the right track and then read it.

  Wow, Sony must use a different concept based on your questions.

  I've never heard of a 'sound loop', don't know what that means.

  You or the other Records audio signals to an Audio track or MIDI signals from your MIDI keyboard on an Instrument track that creates regions. These area can be sealed off by dragging the upper right of the region.

  Then there are loops Apple Loops that you can access from the loop on the right browser. It is MIDI and Audio regions following the tempo (and pitch) of you project.

  It is always harder to relearn software (from another brand) that learning new software. I would like advice with a peak in the manual once a while to understand how different from what you are accustomed to Sony GarageBand.

• several loops with error handling and controll

  I have a project where I spin 4 loops at the same time and must stop all the loops with a stop button as well as all the loops if one of the loops will receive an error.

  Loop 1.

  Loop start

  control the other 3 loops

  Loop 2.

  Analog voltage reading

  Loop 3.

  Digital inputs to read

  Loop 4.

  Write digital output

  Someone knows how to do this?

  Two other methods not mentioned in the otherwise excellent document that mentioned Matt are the use of a global variable 'stop all' and a relative using a Global Variable of VIG/functional.  The reason to talk about, is that they can be used also stop 'detached' live, live which are defined to run asynchronously (and therefore a bit 'out of control') regarding the main VI.

  I use a "combination of ingredients" for some projects I'm developing using LabVIEW 2016 and its support of the channels.  For example, I use a Messenger channel to create something akin to a message in queue manager.  When the event loop detects that the exit button has been pushed back, it puts a Message "Exit" on the channel of Messenger and stops himself.  When the Message Loop sees "Exit", it sends one release Message who else has need to see (in one case, the producer of a producer/consumer model) and stops himself.  When the producer Gets the output Message, it puts a "last element is invalid" on the flow of the channel for consumers and stops himself.  When the consumer gets the message of the last element, he stops himself.  A magnificent waterfall.

  And I work (not yet 100% complete) how to extend this to start the asynchronous calls that do not (yet) support channels as easily...

• How to exit while loop with delay schedule?

  I have a pretty heavy program that iteratively takes a series of measures from a number of channels using a variety OR-Switch and OR-DMM screws that I assembled as a result of various examples and several help pages. Each channel is sampled once during each iteration with data to be saved in a text file for later analysis, after it is imported into Excel. I added to the screen 'real time' indicators and charts to see what looks like running data.

  Each iteration is performed using a While loop with a delay timer, even if a previous version, I used a timed loop. Measures for the series of channels are collected with a loop For inside the While loop. The loop For includes screws which:

  1 cut the channel and wait as debounce.

  2 Initializes the DMM and passes the configuration information.

  3. wait for a while to make sure that the DMM is set.

  4. measure.

  5. close the DMM.

  6 disconnect all the switches.

  The terms of the election of the channels is ends in 15-20 seconds and I am currently collecting data every two minutes, so he spends "wait" time "collection". Each iteration of the loop For initializes and closes the DMM to avoid the hot switch.

  Other components of the program are configuration setting controls, etc. (in front of the While loop), a "current measurement" indicator and a writing-text inside the loop file operation For, several indicators of the iteration (inside the While loop, but outside the loop For) and a bunch of operations related to the grouping and table that provide graphics of groups of time vs measures.

  I don't know there are more elegant ways to perform many functions that I do and I'm not posting the VI here because I want to concentrate on what I know, it's a big problem with my program (for now!) - I can't figure out how to get out of the While loop. I tried the combinations of Boolean control, its conditions of latch and Stop / continuous if true to nothing does not.

  I want a 'Stop' button that ends the While loop, at the next opportunity, but it is not working properly, I think, because the stop button does not play with good timing, because the program runs either the loop For or the time delay at the beginning of the While loop. 'Next opportunity' can mean 'Immediately', 'at the end of the next iteration of the loop,"or"at the end of the next delay schedule." I think that if I get one of these scenarios to work, I can get an any of them to work!

  Help, please!

  
  

• How to stop and restart a .vi with a button front?

  Hey guys, a newbie here.

  I have a .vi with a stacked sequence. First frames are few parameters (LIN master node) and initialization of hardware and hardware data should pass on (the frame response table). In the next section, there is a loop in which the data of sends and receives material (LIN monitor). If I want to change the initialization, settings, or data values, I need to stop the .vi and restart it. I was wondering if there is a simple way to do this with a single click (a button on the front panel).

  An alternative would be to put another loop outiside all stacked sequence, then run it once with a push of a button (the inner loop should leave the reboot on the outside), is it possible?

  I hope I made any sense. Thanks for your suggestions.

  Tomaz

  Ideally, redo the code with a state machine would be the best way to go, if this is so you can add this powerful tool to your Toolbox. That being said, wrapping your existing code in a while work loop, with its own stop button to stop the program, if the execution of the entire sequence is ok. Where you might encounter problems with this, is if there is a step in the sequence that should not be run again, there should be the encapsulation of code from the image of this sequence in a case statement that only runs the first time through. If you have the time, learn how to use a state machine would be a real advantage, really take your LabVIEW knowledge to the next step, if you pardon the pun.

• "Device Failed to Connect" sound notification with no popup at startup once the desktop appears

  When the desktop appears, I sound "dududu" with no popup. I had to look it up in the audio file and the explanation next to it said noise "device failed to connect.

  I currently have no device attached except speakers and keyboard and mouse. I bought a HP Phopsmart printer and installed but it does not work well, so I uninstalled it. I left the USB cable connected to the computer after disconnecting the printer after reboot several times, and then disconnected. At this time the sound notification has begun.

  I don't know if the printer had nothing to do with it. What should I do to fix this? Help, please. Thank you.

• The bloody sound issue with XP (DV7-2000 series)

  OK, if someone has managed to get IDT Audio Codec 100% functional under Windows XP?

  100%, I mean:
  -work the three speakers
  -headhones jack sound
  -cut the touch button turns on properly

  It's the box of dirty work, or nothing but box works...

  sp41398 - is the best driver to date (subwoofer does not work, always red button mute). The fate of two speakers and headphones.
  sp43935 - the last driver I could lay my hands on. Subwoofer only doesn't work, no sound from headphone jacks. The mute button is OK.

  The problem is obviously not in the drivers (*.sys, *.dll) themselves, but in the registry settings. Maybe the INF files are also well screwed upward. I tried to install sp43935 and returned to some settings in the registry as sp41398. I managed to make the speakers work with the subwoofer (with kind of a sound distortion at high volume levels, however). So I just replaced all the files *.inf sp43935 with sp41398 of the *.inf files and installed the drivers updated the. They acted exactly as sp41398 drivers, although the file *.sys and *.dll from across sp43935 most recent.

  Then? Any thoghts? Maybe someone has already solved the problem?

  I finally managed to mod the driver for Windows XP, so that it works almost perfectly.

  Indicator LED works properly, its fate of headphones, Speaker Subwoofer seems to work and no hack stupid devcon is required.

  The only problem now is that the IDT Control Panel works correctly. Well, already it did not work at all.

  If there are still users with Windows XP out there who want a better driver, let me know and I'll upload the driver somewhere.

• Typewriter with a button effect

  Hello... hm, I would like to have a button, a dynamic text and input text.

  When I click the button, the input text will be show in the dynamic text with a typewriter effect.

  I found this script... (a cool script with a sound, when the effect typewriter)

  var mysound =new kb();   
  mysound.play(); 
  var myString:String = origine.text; 
  var myArray:Array = myString.split("");// seperates each letter 
  
  addEventListener(Event.ENTER_FRAME, frameHandler); 
  function frameHandler(event:Event):void { 
      if (myArray.length > 0) { 
      resultat.appendText(myArray.shift()); 
      } else { 
        removeEventListener(Event.ENTER_FRAME, frameHandler); 
        SoundMixer.stopAll(); 
      } 
  } 
  

  To make it work when I run the swf file, but... I don't know the correct way to do it with a button...

  bouton.addEventListener(MouseEvent.CLICK, gogogo); 
  function gogogo(event:MouseEvent):void { 
  //??? 
  }
  

  I can't find. Any idea, please?

  Just move the ENTER_FRAME event listener and the read command sound inside the event handler of the button

  1. bouton.addEventListener (MouseEvent.CLICK, gogogo);
  2. function gogogo(event:MouseEvent):void {}
  3. addEventListener (Event.ENTER_FRAME, frameHandler);
  4. mySound.Play ();
  5. }

• Progress bar when audio plays on a slide with the button

  Hello

  I use 6 Captivate.

  I have a zipper opening for my demo that introduced the demo. This slide contains 1-3 minutes of audio. On this slide, I have a standard button named 'Start', that the learner must click Start the demo (which is on the next slide). I also have a PlayBar with rewind, Play/Pause, Back, Next buttons and Audio.

  Once the project starts, the Play/Pause button on the playback bar turns into mode 'Play '. This, I believe, is an expected behavior because of the presence of the 'button '. However, it causes me problems because, if the learner clicks on the 'Play' button (instead of the start or next buttons) after the end of the audio to the slide of the opening, the progress on the playback bar bar moves for the duration of the audio, so that nothing changes on the screen.

  Is it possible that I can:

  1. Move the progress bar with the button Play/Pause in "Pause" mode when opening, slide audio playback and switch to 'Play' mode once the audio ends? In this case,.

  a. If the learner pauses the audio by clicking Pause and then click on Play, it must continue with the audio.

  b. If the student click on the play button after the audio ends must take sound to the next slide.

  2. turn off the Play/Pause button so that the learner will not click on it?

  I don't want to hide the PlayBar on this slide as I want to give the Rewind option to the learner so play the audio again if he / she wants.

  Anthony

  A colleague found an easier solution than the one I was talking about earlier.

  He just moved the point to pause the start until the end of the slide button. Now, the progress on the playback bar bar moves with audio and the Play/Pause button passes in "Play" mode when audio stops at the end of the slide. On clicking the play button, the project will move to the next slide.

• Problem with interactive buttons

  Hi all

  I seem to have trouble with interactive buttons.

  InDesign CS5 - Version 7.0.3

  I create a document with 2 pages (Pages face is checked).

  Add a text box to each page, Page it says "1" text box and two page says '2 '.

  Text box on page two I right click and select Interactive | New hyperlink Destination - Type: Page, Page: 2, Zoom adjustment: fixed

  On the Page, one I add a sample since the button panel button.

  I select the button and then display the button panel.

  I delete the default "Go To URL" action and add a 'Go To Destination' action using the event to "on release".

  When I preview the page in the "Preview" Panel, I click "Play" and that he can see the first page and the (large) button, but when I click on the button, nothing happens.

  Changes of mouse I have the mouse on the button, the button state changes rolling State... everything seems good, but it is not actually exercise the action of going to the next page.

  I tried the export in PDF and ensuring that 'Include bookmarks' and 'Référence' is checked so that ensuring that 'create PDF containing the tag' is checked, but the exported pdf file does not work the action!

  What I am doing wrong? It seemed so easy when I watched some video tutorials on how to do it.

  Any help would be appreciated.

  Thank you

  Andy

  You export to PDF (Print), by the sound of it, and the buttons do not work in Print PDF. Try to export to PDF (Interactive).

• Sound loop

  Hi all

  I discovered a problem when I was creating a sound loop in Flash. I am using a similar code (here is a short version):

  var sound: Sound = null; It is initialized then not shown here

  var pausePos:Number = 0;     the time at which the noise has been stopped and must be restarted again

  Run sound paused

  function playSound()

  {

  If (Bo! = null)

  {

  Soundtrack.Start (pausePos, 99999); looping sound

  }

  }

  pause the sound and store time

  function pauseSound()

  {

  If (Bo! = null)

  {

  pausePos = soundtrack.position;

  Soundtrack.Stop ();

  }

  }

  On the stage is a button play/pause the sound. The problem is that when the sound is paused and then not again suspended, a loop is executed since the time stored "pausePos". Not only it starts for the first time in the era of "pausePos", but the loop is to the 'pausePos' at the end of his time.

  How can I solve this problem? The ins Manager onSoundComplete't the solution, because then there is a short delay. Any ideas?

  Thank you

  Michal

  you will need to use the full sound event to complete your sound, then.  You can remove the trailing white space in an editor of sounds and derivation of white space using the offset parameter.
