USB interrupt timeout event management

• Edit event managed by this case in LabVIEW 2013 does not show the specifiers of the event, Event Sources and events on screen resolution 800 x 600

  Edit event managed by this case in LabVIEW 2013 shows not specifiers of the event, Event Sources and events on screen resolution 800 x 600.

  As far as I know, the list of supported resolutions is determined solely by the graphics card. It is possible that one used by the PC supports only 800 x 600 as maximum resolution, even if you plug an external monitor.

  Like Dennis suggested, the recommended option would probably be to develop on another PC and only deploy an executable for the industrial PC. That's what we do with our systems (although not because of this problem, but because it makes sense. There absolutely no need to have the IDE installed in most of our systems).

  Other options:

  1. See if you can get an update of the driver from the manufacturer to solve this problem.
  2. Plug a USB Monitor with its own driver.
  3. Try to hide the taskbar and make the smaller title bar in the hope that the bug manifests.
  4. Try remote access in the PC. I think that some remote access programs allow you to specify custom resolutions that are not affected by the original drivers. Remote Desktop seems to be a likely this option even if it has been awhile since I've used it.
  5. Check the BIOS. I saw at least one industrial PC where there was some settings in the BIOS to control the resolution, but I don't remember the details, and it was quite limited. I think that in this case, you can change the resolution, but then the image does not fill the entire screen.

• How can I register for the timeout event dynamically

  Hello

  I found this example:

  http://zone.NI.com/reference/en-XX/help/371361K-01/lvhowto/dynamic_modifying_reg/

  I want to do the same thing, except that it is not the event of moving the mouse I want to toggle (register/unregister) but the timeout event.

  The time-out period is in the drop-down list of the events, I can sign up for, but it is grayed out.

  How can I do this?

  Thank you

  
  

• How to use 'Start synchronous call' to run a Subvi timeout event and keep in hand vi still running?

  Hi all

  I have an application must periodically check the State of the instrument, and I put it in the "Timeout" vi main event. I need also call some subVis to configuration etc. Somehow when I called these Subvi, the Timeout event in my main vi did not work. I then use the ' Start Asynchronous Call "to call the subVis. Turns out it works fine with a few subvis worthless back, but not as expected with subvis 'return the required value.

  I have attached a simple test, my main vi call two dlg subvis: AboutDlg.vi and SettingsDlg.vi. In the case of delay, I just use a counter for the simulation. When you run it, you can see the meter taken into account when the AboutDlg.vi has been called, but stopped when SettingsDlg.vi is called.

  As I remember, someone suggested to use the queue to pass the return value, but I don't know how to implement here.

  Anyone have any suggestions on this subject?

  Thank you very much.

  Try to play with it - I modified your code to search a Q in there.

  You want to change the bunches to data types more useful (perhaps enum and Variant, so you can ungroup variants according to the enum contribution), you can type def clusters to make it easier to maintain and you will need TO handle the situation where the called VI is left open on program close - I couldn't be bothered, as it was not your immediate deliverance)

  Hope this give you some ideas - totalyy not tested, but should work.

• Controls that trigger cases of timeout event structure

  In a structure of the event, we can understand the controls in the event of timeout. But if we do it this way, we do not get event data node associated with the controls. I don't know if it is a good practice and whether there are issues listed. Please comment. Thank you.

  A 'practice', it's what you do. You talk about a limitation (or characteristic). Event data nodes display only those items that are common to all the events of this particular event case, so for example "old/new val" is not available if there is also a timeout that is assigned. If you do not need them, it does not matter whether they are there or not.

  This often isn't a problem because you usually only the new value and you can get that by placing the terminal control inside this event.

  If you need the specific event data node, create an otherwise empty case event dedicated to control and raise the timeout event temporarily affecting the timeout to zero using a shift register. Set the time-out period to zero in the case of timeout events. If the new value is also necessary in the case of a time-out, leave the Terminal inside event newval event data node timeout usage in the case.

• Click of the mouse on the chart without event management

  Is there a way to detect the mouse click on a chart without event management? My version of LabVIEW database has no events management features.

  Thank you

  Ryan

  Sweet justice.  Because you were a guy standing, my scorn is now much closer to 90/10.  They should really sign make an acknowledgement that you know what you get.  I don't think it's unreasonable to expect basic functionality, and IMO event Structures are pretty basic.  This is why I'm not in marketing.

  Time of experience.  It may be while you are unable to change the structure of the event, maybe you can run code that contains and edit around them.  Here, I use a structure of the event to a mouse event down to the chart.  Normally, I'd put the code inside the occurrence of the event, but maybe you can not change the inside.  Instead, I pass a boolean that is true when the mouse down event fired and pass out the XY coords as well.  You can do something within a structure separated from cases as I show.

  I would like to know if it works.

• Popup list event management

  Could someone list popup work? I tried to add one to my request and I was able to get the list to come but could not do the work of event management. The code between any events management function. Can someone please take a look at this code and see what is missing?

  Thank you

  Hi, Maxim,.

  his was discussed before any stretching of the BaseDialog is an error with the DialogEvent of management class. Use the following code to correct your mistake. It should do the job:

  Replace:

  popUp.addEventListener(DialogEvent.DIALOG_BUTTON_CLICKED, repeatButtonClicked);
  

  With:

  popUp.addEventListener(Event.SELECT, repeatButtonClicked);
  

  your function to retrieve the event will look like this:

  public function repeatButtonClicked(e:Event):void
  {
      trace("Selected Index of Button: " + e.target.selectedIndex);
  }
  

  that should do the trick. Here's the forum thread, you can check for more information:

  hope that helps. Good luck!

• Anyone know a good event management tool that integrates well with Eloqua?

  Anyone know a good event management tool that integrates well with Eloqua?  The tool would deal with everything associated with the event as: management agenda, registration, monitoring, reports, etc., but integrated with Eloqua in a way that allows you to trigger emails to confirmations, reminders and thank you and facilitates the exchange of information of contact/participant and campaign.    Think of something as integration between Eventbrite and Eloqua (although we are not looking at Eventbrite specifically).

  Any suggestions?

  Hi Kurt -.

  We've been Cvent users for two years and it integrates very well with Elouqa. If you have any specific questions, feel free to give me a shout - I manages all our events and am happy to give feedback.

  See you soon,.

• Event management issues

  Hi guys...

  I do a code of event management and am having some problems. I have placed the following on the scene, a button to send including the instance name is 'btnSubmit' and a label whose instance name is "lblTest. The ActionScript 3 code resides in a separate file of "Maxwell.as". In the "Maxwell.FLA".

  file, I typed "Maxwell" in the document class properties. Here is my AS3 code:

  package
  {

  import flash.display.Sprite;
  import flash.events.MouseEvent;

  SerializableAttribute public class Maxwell extends Sprite
  {

  public void Maxwell()
  {
  the constructor code
  }

  private void sendMsg(e:MouseEvent):void
  {
  lblTest.text = "Clicked".

  }

  btnSubmit.addEventListener (MouseEvent.CLICK, sendmsg(2));

  }

  When I do a "CTRL + ENTER" and run the program I get the following errors:

  Access of undefined property btnSubmit.

  Access of undefined property sendmsg(2).

  I don't understand why I get these errors. I already connected the two files by typing "Maxwell" in the

  document class window and "sendmsg(2)" is also the name of a function. I hope someone can advise me. Thank you.

  Your add the listener code is outside any function - you can do that with classes. You can put it in the constructor:

  package
  {

  import flash.display.Sprite;
  import flash.events.MouseEvent;

  SerializableAttribute public class Maxwell extends Sprite
  {

  public void Maxwell()
  {
  the constructor code

  btnSubmit.addEventListener (MouseEvent.CLICK, sendmsg(2));
  }

  private void sendMsg(e:MouseEvent):void
  {
  lblTest.text = "Clicked".

  }

  }

• Link Block event management

  Is it possible to block the event Manager is so that if the user clicks on a link, nothing happens? I want to validate links and offer the ability to create internal links that navigate in the application, but no matter what are the parameters of the event listener for the event click on the textFlow can pass it always tells the browser to access the location of the link.

  Thanks in advance.

  I discovered that there is a way to do it. If you listen to the CLICK event, and then manipulate yourself and call preventDefault() on the event, there will be no default handling of the connection (that is, it will not bring up the browser).

  So in your event handler, where you listen to the LinkElement MouseEvent.CLICK, add something like this:

  If (event.type is MouseEvent.CLICK)

  {

  ... your handling goes here...
  Event.preventDefault ();

  }

  Sorry I didn't see this before. I hope that helps!

  Create a variable username you adapter, go to the list of Variable in the adapter and click Add. Do set during execution.

  Once the adapter of the entity is created and you put this device in the data object manager ==>.click on Attach pre users insert and save.

  Go to the tab cards card, here, you can select your adapter and double click on the variable User ID and map it to entity field - USR_LOGIN.

• On a chart or an area of events management

  Hi all
  Is it possible to do event manages on a table or on a region? For example, I traced a 2d graph if I click on any part of the chart I need to see other tables. Is this possible to event management? Do I need to write code in java script? Pointers to this will be a great help
  
  Thanks in advance

  Hello

  as you can find in the documentation: graphical http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/app_comp.htm#BCEIJJID queries have a special syntax.
  The first parameter of the request (which is usually ZERO) can also be a link to a page (syntax see here: http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/concept.htm#BEIJCIAG).
  So when a user clicks on a bar of your chart it will be redirected to the page given by the link.

  As far as I understood that this should do what you wanted.

  Best regards, Tine.

• USB Interrupt IN endpoint data

  I am developing firmware for a USB instrument and widely using the NI-VISA to test and debug.  I would like to be able to read the data packets that comes on the Interrupt IN endpoint during a USBTMC service request - USB488.2 (SRQ).  I think that the firmware did the right thing because this code works:

  ViSession defaultRM = VI_NULL, instr = VI_NULL;
  
  Turn off State; allow to Set mutual FUND (done) in the State of the event;
  
  BSE (event status bit) scheduled status Byte enable Register; start a
  
  order with overlap; and generate a service request (SRQ) when
  
  the operation is complete.
  
  ViByte buf [] = ' * CLS; * ESE 1; * SRE 32; : SYST:ARR:CLK 2304; * MUTUAL FUND ";
  
  ViUInt32 cnt;
  
  ViUInt16 STB;
  
  
  
  viOpenDefaultRM(&defaultRM);
  
  viOpen (defaultRM, "USB0::0x0000:0 x 0001: 0:INSTR", VI_NULL, VI_NULL, &instr);)
  
  Service request events go in the standard event queue
  
  viEnableEvent (instr, VI_EVENT_SERVICE_REQ, VI_QUEUE, VI_NULL);
  
  Launch a command with overlapping that takes awhile to finish and wait that the
  
  service request indicating that it is finished.
  
  viWrite (instr, buf, sizeof (buf)-1, &cnt);)
  
  viWaitOnEvent (instr, VI_EVENT_SERVICE_REQ, VI_TMO_INFINITE, VI_NULL, VI_NULL);
  
  When you receive a VI_EVENT_SERVICE_REQ on an INSTR session, you must call
  
  viReadSTB() to ensure delivery of future service request events on the
  
  given session.
  
  viReadSTB(instr, &STB);)

  viWaitOnEvent Gets the event, and the status byte, I read the right fixed flags (SRQ and BSE).  As the value of status byte is transmitted the USB device to the host computer in a package from the Interrupt IN endpoint, it seems that he must do this package.

  I would like to see this package.  But several things, I tried to get it from NI-VISA have so far failed.  For example, I tried to install this reminder Manager:

  public static ViStatus _VI_FUNCH interrupt_in_hndlr (ViSession vi, ViEventType type, ViEvent, ViAddr userHandle evt)
  
  {
  
  	HANDLE interrupt_in_event = userHandle;
  
  	ViUInt16 size;
  
  	VI_ERROR (viGetAttribute (evt, VI_ATTR_USB_RECV_INTR_SIZE, &size));))
  
  If (type! = VI_EVENT_USB_INTR)
  
  		Return VI_ERROR_INV_EVENT;
  If (size > 0) {}
  
  		ViPByte buf = new ViByte [size];
  
  		VI_ERROR (viGetAttribute (evt, VI_ATTR_USB_RECV_INTR_DATA, buf));
  
  		printf ("interruption-IN = data");
  
  		for (int i = 0; i)
  
  			printf ("% 02 x", buf [i]);
  
  		printf ("\n");
  
  	} else {}
  
  		printf ("data without interruption-IN! \n") ;
  
  	}
  SYSERR (SetEvent (interrupt_in_event), FALSE);
  Return VI_SUCCESS;
  
  }

  with this code

  	HANDLE interrupt_in_event;
  
  SYSERR (interrupt_in_event = CreateEvent (NULL, TRUE, FALSE, NULL), NULL);
  Install a handler for the events of interruption USB-IN
  
  	VI_ERROR (viInstallHandler (instr, VI_EVENT_USB_INTR, interrupt_in_hndlr, interrupt_in_event));
  
  	VI_ERROR (viEnableEvent (instr, VI_EVENT_USB_INTR, VI_HNDLR, VI_NULL));

  and he is never called.  I tried to put these events in the standard event queue, and the call to viEnableEvent fails.  I tried to open the: RAW device instead of the: INSTR device and who fails.

  Can someone lend me a clue?

  For interruptions of the standard USB488 subclass (related to the status of the request READ_STATUS_BYTE SRQ), interrupts are handled by VISA. So, if it is an interruption of the SRQ and you have SRQ active event, which should be raised (that you see in your example). It would be the only time wherever your USB_INTR event is raised for other types of interruptions (i.e. vendor-specific interruptions). Is there a particular reason you are trying to get the data of interruption for the standard interruptions? The only data is the status that you get with viReadSTB call anyway, right?

• Unexpected behavior with several structures of events manages the event itself.

  Hi, does anyone have an explanation of the following behavior?

  After 'Boolean 2' is enabled and then disabled the program "freezes". You can always pause the program but nothing does.
  For example, by pressing one of the file, Edit, View, project, Operate, tools, Windows, help or any other object inside the VI.

  This happens if I have two event structures who want to handle the same event, even if the flat sequence should be allowed only one run.

  

  This isn't a bug.

  Structures of the event should be used to handle different events. Given that you have entered your Boolean event in the two structures of the event, the event gets queued both when it occurs. This means one or the other be expected to manage the event and will, by default, lock the application. In the scale-measure of LabVIEW architectures, usually there is a structure of single event that handles all the events and then sends messages to the coast to the rest of the application to manage these events.

  There is a "Table locking" checkbox in the event dialog box which is by default enabled, but you should leave it on because it leads to bad practices otherwise.

• interrupt an event of any other event handler

  Is it possible to have an event that interrupts another handful rutin event? I mean, I have an event handle the structure with several events (case). One of this event takes place, and the structure begins to run in rutin. Meanwhile, rutin is running, another event takes place. Is it possible to stop rutin from first event to run the other?

  Thank you!

  No. not really.

  Structures of the event has no any code embedded in them that can take a long time to run and block the other events.  If you do not have one such routine, you must move to the other while loop using an architecture of producer/consumer with queues.  The structure of the event would just load a command into a queue that the other dequeue while loop and start working on.  The structure of the event loop will become quickly available to treat other events.

  If the second event is one that is designed to interrupt the first routine, then you just need to have the right communication architecture to send to the other loop.  This could be another queue order, perhaps a declarant or accident.  A local variable or functional global variable.

  Remember that you can not stop any structure in the middle of its processes.   A time of loop can be stopped, but all the code in the while loop should run before this iteration of the loop stops.
