• create subroutines for several structures of the event and common stop button

  Hi guys,.

  I wonder if there is a better way to design algorithm below scenerio that similar technical rehearsal for each structure of the event.

  Please find in annex vi where I designed the code to a boolean (D). I want to design a similar code for all other bolleans. (In the present design code, photo is displayed when the mouse is flown over D). I obviously have other pictures for the other,(A,B,C,E,F) booleans. Can we have a kind of subroutines for other Boolean types and a single stop for all the application button.

  Thank you very much in advance for your support.

• How to use the structures of the event for long-running tasks

  I created a state machine that scans a cluster of Boolean controls in a State of 'home '. Most of the States run a Subvi or two in ~ 100 ms or less.

  However, a State run for 10 seconds.

  The code works but the user interface is limited because the controls are outside the cluster because they provide inputs to the structure of State machine case but do not cause changes in the State. In other words, I all orders cluster stacked vertically on one side of the main panel and do not have the flexibility to move the controls to the more intuitive positions on the Panel.

  My question: How can I convert this code in a structure of the event and keep this long term 'event' and prevent that the operator by clicking another button event during the execution of this event?

  Thank you

  You say you have controls outside of your main code... You should really put these inside and manipulate them in a State of your state machine is initialized. This allows you to make changes to the code easier and limits of line entering your outside loop.

  You can do different things to lock the user.

  You can disable specific controls so that they can't be clicked or edited.

  You can use the palette of the mouse to define the busy cursor and disabled again once finished, I do this a lot during treatment when my code something loads the user just clicked.

  One of my favorites is to set a Boolean value in your data that passes through you event titled structure "disable mouse." When the value is True, a mouse down event will effectively reject the event, clicking on disable. I also added an event mouse move where if the bool disable the mouse is set to True, it moves an indicator of string with the mouse by telling the user why it is disabled.

  If you want more specific suggestions, I suggest to post an excerpt of your code, or attach your screws, so that we can better help you.

• Structure of the matter and structure of the event with a condition of the indicator (boolean)

• Structure of the event with sub-panels

  Hi, I tried to find a simple example with a structure of the event and only two sub-panels.

  I found the 'new Event Handler.vi' and I'm doing something with two sub - vi I did 'Add.vi' and 'Mul.vi '.

  To be able to switch between the two sub-panels used in 'New Event Handler.vi', the programmer used a "time surge" which I can't locate

  anywhere, so I just copied 'new Event Handler.vi '.

  I can't get this to work.

  Take a peek inside the world

  Sincere greetings,

  Lasse

  Hi Lasse,

  Yes, there is. If you open the properties of the subVIs Add.vi and Mul.vi (Ctrl + I), you can change in the tab 'appearance of the window' to that custom... There is an option display front panel, when it is called and the close later while initially closed just sellect them. Then, you will have the effect of 'pop up' :-)

  I slightly changed the example, so that can see them in the form of pop-up windows.

  See you soon

• How to stop the While loop in the Structure of the event with the same button?

  

  Hello

  I have a problem. I want to use a single control to activate an event in a structure of the event and the same control to end a while loop in this case.

  It is possible to use 2 controls to do this, but I need to be alone.

  Thank you

  You should NEVER place while loops inside the case of the event, and it is never necessary to do. Think about it: all you have to do is spin the code. You can easily use the outside while loop for everything. Simply place the code of the loop internal (without the inner loop) inside the case of delay and manipulate the time-out period between a pending finished and the infinite (-1), depending on the State of the Boolean value.

• by using a structure of the event to restore a Boolean control with change in value for the menu ring

  I'm trying to get two Boolean buttons to reset when the value of a ring menu.  For this I use a structure of event defined to execute with a ring value change.  However I have another code that should be run while the structure of the event expected to change value.  I place my structure of the event inside the while loop buttons reset as expected but my other code is not run (except when the value of change). If I place it outside the loop the rest of functions code as expected, but the buttons do not reset.  Any help you offer is much appreciated.

• An interrogation continues with the Structure of the event, please help me understand

  Dear Forum,

  I'm 3 months in LabView. I created a front panel with what I consider a reasonable set of code below with a basic entry control power boulean a case controlled set of actions. I enclose a strongly striped version to the bottom of this structure with sections deleted button so that the executed code is removed to simplify just ask questions on this control structure. After the recent webinar, I understand this form of control to call a continuous structure of vote - and it makes perfect sense and seems natural for me to the point of programming of data flow.

  But according to the webinar it is preferable to use the structure of the event.

  However, the structure of the event seems really weird to me. My main question here is certainly the structure of the event MUST be voting each of the values itself anyway, otherwise how does he know that an event had occurred?

  So what is the difference between explicitly "polling" the buttons myself with a while loop and using a complex (for me) of the event with 'hidden' polling stations under?

  The vote of the 4 buttons in my example should be done at the same time if Labview is truly multithreaded/parallel? There should be no difference in the level of the computer between my code querying and the code 'hidden' the structure of the event making the mark.

  Thank you in advance for you help to clarify my confusion.

  Sincerely,

  Robert Gibbs

  BONE is already this process in any case.  If you are in fact doubly effort without worrying.  And the OS is much more efficient that your code will be.  So just let the OS do work heavy while your code sleeps.

  And think about the trigger more as an alarm clock.  You are asleep (do nothing, with no CPU) when your alarm goes off.  You wake up and perform the task that the alarm tells you to do.  Once done, you are waiting for another alarm, so you get to sleep.

• How to control a VI (with a while loop and a structure of the event) from an another VI

  Hello

  I have the main VI which I want to be driven from an another VI. But I can't do that and I don't know what is happening.

  For example: VI main, I have a while loop with a structure of the event, there is a Boolean controller controlling a Boolean LED, which is inside the structure of the event. And the other VI, there is just a Boolean controller and functions of applications to open the main VI.

  How can I control the Boolean LED in VI main, changing the State of the Boolean controller in an another VI?

  Thank you.

  There are different options, but depending on what you want to do. For this example I can't give you a specific solution.

  I do not understand why you do what you do. Why do you call your 'principle VI' dynamically? What is the advantage to do? There are also other ways to call a VI dynamically, based on real cases (for example the method "call and forget", etc...).

  In you principle VI, control you Boolean ("THATCHER") is not the case of corresponding event. This is not usually a good practice, keep it inside.

  Also, why you try to communicate with the caller and callee VI through such a way to twist? There are better ways to do it.

  In one of my projects, I use the user event to launch orders in case of case of appellant VI.

• Structure of the event: problem with data transfer

  Hello everyone,

  for three days I'm troubleshooting an issue in LabView with the event structures. I really hope someone can help here, because I can't find anything on the entire WEB.

  I had six groups of equal to a VI entry, each containing five checks enum (among others) where the user can specify some configuration of measurement data. I want the program to do is: to recognize if a any of these enum values has been changed and if yes, then submit the values containing the cluster in a subvi then calculates the wiring and affect the material of the ports. In addition, i need to submit the number of the enum element that was changed, so the program is able to clear the user input in the case of a breach (e.g. If the user sets two entries of enum control 1 meter and 2 Group 1 and then tries to set a third counter of entry to port 3, the program displays a message and deletes third entry as the number of entries of counter is limited to 2 per cluster).

  To resolve this problem, I used a structure of the event with 6 x 5 cases (change of enum value 1 Group 1 Group 1 enum value 2 change... and so on until the change in the value enum 5 Group 6).

  

  The problem is that if the user changes a value, the event structure reacts and performs the proper case; However VALUES of the cluster, the user changed are not subject to the SECOND time that an event occurs. It is a kind of a situation, "n-1". For example, if all five controls Enum of Group 1 are 'disabled' first and the user sets enum 3 of 'Meter entry', the structure of the event runs but submits the values previous to the Subvi (all enums 'Disabled'). When the user makes the second change, say that enum SWITCH1 to "Analog Input", the structure of the event is running again and passes the values of the FIRST user to the Subvi editing, then the Subvi gets data "enum 3 meter inlet and all other disabled enumerations.

  In easier words: if I have new values on my cluster "Kanal 1" (left side of the screenshot) and run the structure of the event, on the right side to "Kanal 1" indicator, I get the previous values (n-1).

  The structure of my event is in a while loop. If I create a timeout every 10 ms, and a loop of 250 ms the waiting time, I got the 80% chance that the recent changes are transferred to the Subvi correctly, in other cases I have a delay of the 1 step as described above. It seems to be directly based on the time that I specify the while to wait - but I can't explain it and I cannot accept a less than 100% chance to transfer the correct data, nor can I accept delays of a few seconds for each loop run. If I indicate timeout (infinite) get delayed 1-1 step values in all cases.

  When I specify cases of event to react on "all items value change" of the structure of the event behaves properly - but then I can't handle indicate which element has changed, as the CtlRef of output in case of a structure does not specify "enum 1, enum 2..." but only "Group 1".

  Does anyone have a solution to this? It is certainly a problem with the structure of the event, but I can't understand what to change.

  Thank you much in advance,

  Mr. Boiger

  This is because the terminal is read until the structure of the event runs.   Terminal is read, the event structure is waiting for an event.  The change in value.  Business events are running, but the value is the old value.

  Put the terminal inside the event.

  Or, you can display the connector called "New value" on the side left (stretching down from the border of the node 'CtrRef').  Use a wire one to come.

  Recently upgraded to El Capitan, I had that problem for Mail stop unexpectedly when I saw some posts.  I followed the steps and was able to remove the trouble messages.   Now I can't restore the mail window message viewer component.  When I try to catch the separator bar to go back to the left, only half of the small arrow icon and line appears, and it cannot be moved.   Can open the message by double clicking a message viewer.

  Hi there, alicefrompa!

  Thank you for using communities Support from Apple. From your post, I understand that you do not see the Message Viewer box which allows you to read your e-mails; only see you the Inbox that includes a brief overview of the message and are unable to restore access using the separator bars. I have had this happen to my own Mail app and am happy to let you know how I could fix!

  You are really on the right track - you want to roll your mouse over the divider between the Inbox and sections Message Viewer (which should now be on the extreme right edge of your mail window) and drag it to the left.  When you click on the receipt/Message Viewer box, the cursor turns into a line continuous black with a single arrow pointing to the left. When you see the cursor change, click with the left button of the mouse and (while holding down the mouse button in) drag the combination line / arrow to the left. You may need to drag a little further than before to get it. I had to hang mine almost completely in the middle of my Mail app before the display of the message box appeared.

  From there, you should be able to adjust the boxes to your widths you want as expected.

  If you are still not able to get the display of the messages visible after have try this, here are a few more things that you can do.

  1. Press command + O on your keyboard.
  2. Exit the Mail application, and then press on and hold the SHIFT key on your keyboard while reopening.
  3. Restart your Mac by selecting the menu  Apple in the upper right of your screen restart from the menu drop down.

• Control the Structure of the event with text file

  I'm new relativaly in LabVIEW (experience only about 2 weeks). I am currently control a stepper motor using a structure of the event. Similar to the sample code given by LIFA, I entered my settings how the engine not move away, then press a button on the windows before, and it works this way. I also have other equipment that works as well in LabVIEW, as a transnational step; all components operate individually.

  Now, I'm trying to make the more automated system and to ensure that all the different equipment work in the same code. So, I tried to implement a structure of the event using a text as an input file to try to control events. The text file has a table 1 d of numbers going down vertically (only the line numbers change). So, I used a table of index function to take the numbers one by one, use a loop (while loop in this example) to go to the bottom of the column of numbers. However, the event not register the change, even if the indicator shows the value is changing.

  Attached, it's my test code and the text file that I use to try to control the structure of the event. Please let me know what I am doing wrong. Thank you.

  Oh, now I understand what you tried to say. I'm using a loop and a case structure to activate different events with the entries in the table. I thought case structures and event were the same, but you taught me the event structures are used just for the façade stuff. Thank you all!

• Right-click in the structure of the event for Mac OS

  I put a right-click to activate a case of event (with the mouse down? function) in a structure of the event. It works fine in Windows 7.

  But when I try this in Mac 10.10. This does not at all.

  I connected an indicator in the "button" in the case of the mouse down and found the two clicks left and do a right-click returns 1.

  In Windows 7, left click returns 1 and do a right-click returns the value 2.

  Does anyone know how to activate the right click for the structure of the event under Mac OS?

  Of course, you do.  When you get your press conference button, you say your state machine to move to the State of logging.  You must also make sure that you return to visit the State to wait for the event to check out the events of the stop button.

• Synchronization of 2 loops while one with a structure of the event.

  The work combined well screw and it gives me the results, my question is, in the long run it will give me issues. Do I still need to synchronize?

  Thanks for all the help.

  There's no problem because loop additional lower with the structure of the event.

  Personally, I worry about the top loop. Why so complicated? Why so much duplicate code? Why all these hidden indicators serve as local variables?

  Why don't simply place you the table in the entire cluster in a shift register and the index and ungroup by name wharever value, that you need to access. No hidden local variables or indicators.
