Problem with nested structures event

Hello

I'm rather new to Labview and I wanted to use a structure of nested in one of my programs at the event.

However, I seem to fail to do things.

I created a minimal example of construction that I use, you will find in the attachment.

The idea behind this program is as follows.

1. I have run the program and go into a while loop

2. once I have hold down a button on front of a counter is increment every 100 ms.

3. when I release the incrementing buttun stops.

However, this does not work. What I am doing wrong?

Thanks in advance!

Never stack event structures. Never ever.

That being said, your code contains a lot of illogical parts, for example a queue time when using a case of 0-timeout event.

Please use a unique event structure. Where growth is expected to run, set the timeout case e .g. 100 (using the shift register) and once it is based again on set it back to-1. Initialize the shift with-1 register.

Also avoid using references and nodes property to read/write the values. These are bad practices (in most cases) and bury a lot of run-time performance.

A second shift register allows to keep the numerical value and increase the value in the case of timeout. Update of the terminal after the structure of the event.

Norbert

EDIT: My first line is a rule of thumb. With the increase in the skills of LV and appropriate design, the stacking of the structures of the event is possible, but you must know the rules. If this isn't the case, you won't fail hard.

  • Problem with the onChange event

    Hello

    I am currently facing a problem with the onChange event when you use a datefield entry type.
    for example
    < cfinput type = "datefield" name = "date_txt" width = "175" mask = onFocus = "date_txt.disabledDays" dd/mm/yyyy"= [0.6]; "tabindex ="1"style =" "text-align: left" onChange = "checkDate (); ">

    And then, when I alert the selected date in checkDate function, I still get the old figure.
    for example
    public function checkDate (): Void {}
    Alert ("Date:" + date_txt.text);
    }

    For example if the date displayed is 05/05/2008 and I select another day (05/02/2008), then when the alert box appears, it still shows 2008-05-05.

    Any idea on how to solve this problem?

    Is this a bug with Flash Forms?

    Thank you and best regards,

    I suppose that the function onchange occurs before the value of text is actually defined.
    Use the correct value
    Alert ("Date:" + date_txt.selectedDate);

  • problem with tab structure control and event

    Hello

    My program has a tab control. In each tab, I have an event structure to control some events.

    I encountered some problems. These are:

    1. in each tab, I set tab as an event control, to altogether from the structure of the event as tab change (for example, the image below). My first problem is that when I change the tabs, in the arch depending on whether my program is entered in the next tab environment, happening at the event: change value to main tab! And gives bad result.

    2 - I've scheduled two final tabs as below in the image. I had no routine in these two tabs. Simply, I want when I change the tab, it goes to the next case of the tab control. But when I run the program, it goes to something as busy after one or two changes tab and did not work properly.

    Could someone help me please?

    Thanks in advance

    I wrote this code with some time within each tab loop this case hase 3 for each Boolean control. The result is true.

    But I think that if I write it with a structure of the event within each tab instead of 3 cases, the cpu load will be lower.

    Is it not true?

    Make a unique Structure of the event.

    Add events for all controls (buttons, Boolean)

    When the event is triggeredcheck for active tab control and decide what void / vi to run

    It will work fine you

  • Strange problem with the keyboard event listener

    I have a full screen touch app. To close the application, I set an event listener on keyboard for the key "0". I don't want the press user due to some restrictions Alt + F4 key combination. Problems begin when the application loses focus. Here's the code;

    protected function onComplete(event:FlexEvent):void
    {

    this.setFocus ();
    this.addEventListener (KeyboardEvent.KEY_DOWN, trapKeys, true, 0, true);

    }

    private void trapKeys(e:KeyboardEvent):void {}

    If (e.keyCode == 96) {}
    This.Close ();
    }

    Else if (e.keyCode == 48) {}
    This.Close ();
    }

    }

    When the user change the screen to a different with Alt + TAB application, or any other combination of keys flex app loses focus and does not work when he turns back to my app "0". How can I solve this problem?

    Thanks in advance.

    Hi, Ahmed.

    I have absolutely no problem with the solution you are trying to set up - you use mode full-screen interactive mode of keyboard?

    Please consider:

    on full add keyboard listener

    protected function applicationCompleteHandler(event:FlexEvent):void

    {

    this.stage.addEventListener (KeyboardEvent.KEY_DOWN, trapKeys);

    };

    //

    protected function applicationActivateHandler(event:AIREvent):void

    {

    If (this.stage)

    {

    switch the State to display full-screen when activated

    If (this.stage.displayState! = StageDisplayState.FULL_SCREEN_INTERACTIVE)

    {

    this.stage.displayState = StageDisplayState.FULL_SCREEN_INTERACTIVE;

    };

    };

    };

    //

    private var exitHandled:Boolean = false;

    on NUMBER_0 | NUMPAD_0 exit-close

    protected function trapKeys(event:KeyboardEvent):void

    {

    If ((event.keyCode is Keyboard.NUMBER_0

    || event.keyCode is Keyboard.NUMPAD_0)

    (& this.exitHandled == false)

    {

    exitHandled = true;

    this.stage.removeEventListener (KeyboardEvent.KEY_DOWN, trapKeys);

    This.Close ();

    };

    }

    (Note: applicaton of the events 'applicatonComplete' and "applicationActivate" are routed to over managers)

  • Problems with nested events click and ellipse objects

    I thought I would have this now, but after several attempts, nothing works.

    Got a series of circular objects nested inside are drawn using the ellipse tool in a symbol called "box" of each symbol Click event. When you click on it, symbol must hide or change the CSS attributes or anything really. Tried a bunch of examples, and there are four variations in my .zip file. None of them work and some are ones I previously used. So I don't understand why this isn't working and what should be the right code. I tried getSymbol, stage and Composition. None of them worked. Then what?

    Hi, ladobeugm-

    Try:

    SYM.$("C1"). Hide();

    It's the same as:

    sym.getSymbol("c1").getSymbolElement () .hide ();

    sym.getStage () .getComposition ().getSymbol("box").$("c1").hide ();

    sym.getStage () .getComposition ().getSymbol("box") .getSymbol ("c1") .getSymbolElement () .hide ();

    Hope that helps!

  • Problem with a structure of business

    I have the following problem:

    I want the structure of the REAL of the largest structure case case to start only when I go through the button and activate the TRUE position. I have observed with the tool probe as the structure is always run in backgroun even if a case is false. I want to start from the first position (the default case) the structure of cases each time I'll go through the button. I hope I made myself clear. Thank you

  • Virtualized ESXi5 - network problems with nested VMS

    Happy new year!

    I am facing some issues on my test environment, which is as follows:

    • -my host system is a step of laptop Linux Mint 11 (2.6.38 - 8-generic #42 - Ubuntu SMP)
    • -I'm using VMWare Workstation 8.0.1 build-528992
    • -J' I install bridged networking on a virtual interface (made with brctl) for all virtual machines and the host provides dhcp, dns, tftp, etc... facilities
    • -All virtual machines are on the network briged and all see each other, the host and the internet perfectly well

    Now the part ESXi:

    • -the server ESXi 5 (free basic license) is vitualized with a single vnic and bridged networks (same as all other virtual machines) and as a virtual machine of ESXi 5 (was a nice surprise to see that the 8 WS knows out-of-the-box)
    • -J' I install that some virtual machines nested in this virtual ESXi
    • -the VM ESXi can talk to other systems, that is, the host, the other virtual machines and its own virtual machines

    The problem is that nested virtual computers can talk to each other or the console, but not to the computer host or other virtual machines, except the ESXi itself.

    I have tried the following with no chance:

    • -Add an another vnic to the ESXi and devote a vswitch for virtual machines
    • -use NAT or network invited only for the VM ESXi
    • disable/unload the ESXi firewall

    The only thing that works are a little DHCP, although it seems the acknowledgement never reach nested VMs. However, they still get a correct, but after that IP address are not able to receive any ARP traffic. If you manually add arp entries and can see CIMP inquiry vnet0 (bridge) of VMs nested to other machines as well as the corresponding answers. If ping on the other hand, I see only the applications, which means that the traffic is not sent to the nested virtual machines.

    The vswitch ESXi is configured to accept the promiscuous mode, change MAC address and forged passes.

    Thanks in advance if anyone has an idea

    "Promiscuous" mode is enabled for/dev/vmnet0 on the physical host?  See http://kb.vmware.com/kb/287 for more details.

  • problem with file structure.

    Hello

    Im trying to import video into Flash. I've converted an flv and use the workflow of flash media with a standard game server option and the stop bar.

    I imported into it and it works find when you select just the individual swf that it loads in. The problem im having is that when I go to it through the home page, all the loading of the page apart from the video.

    Ive tried to move around, movement where all assets for video are ect.

    I know that the file structure is important to this work.

    I have a main folder called interactive / and have a FLA and a SWF file and the swf and fla home page.

    Currently I have the swf video in the file swf with the flv and swf playback and stop.

    Any ideas?

    Thank you

    you change the code in the swf file that is loaded by your main swf.  This should be the same swf that loads the video.

  • I have problems with libraries and events in final cut pro

    I use Final Cut Pro X. was used for 3 or 4 years. I just upgraded to latest version 10.2.3 and I use it on an iMac running El Capitan. The way in which the library is set up is very confusing to me and I can't seem to follow the events and projects on individual drives. It seems all the events and projects are bundled in the libraries, but I can't see them on my hard drive to move or archive them individually.

    And they take almost all of my hard drive.

    I am use to working with events on a separate hard drive, but now I can't seem to put the files on a separate hard drive.

    Just looking for advice or direction here.

    Thank you!

    Looks like you were using an older version of FCP X?

  • Problem with the Structure of the case

    Hello

    I added a new structure of matter in my VI. However, once added, there is an error that I have really no idea how fix it.

    The error message:

    "Business Structure: selector values are not unique.

    "A value of the selector is used by more than one case.  "It can be in the middle of a beach in one of the cases".

    Could someone help me please.

    Thank you.

    Floret

    Please your zip code as an attachment. See your code will make it much easier for us to understand your problem.

    The error relates to the distinction between each image of the structure of your business. You can have two business executives who launch for the same input selector case.

    For example, if I had three managers of cases that have been '0..', '1', 'Default', then frame 1 & 2 times would launch if the entry is 1 (this is not allowed). Check you definitions of statement.

  • Problem With nested Manager in DialogFieldManager

    I display successfully a PopupScreen with an icon, title, two fields of line and two buttons to the right places.  I do this by calling the constructor of PopupScreen with DialogFieldManager

    The problem is fixed height BasicEditField as I am trying to add.  There is space for the BasicEditField, but the BasicEditField is not.

    Here is the code I use.  Note: I left the ButtonField and FieldChangeListener code to stay brief.  I also tried to use customManager.add () instead of delegateFieldManager.addCustomField ()... or work:

         eflink = new EditField("", link);
            efname = new EditField("", "");
            befd = new BasicEditField("", "")
            {
                public int getPreferredHeight()

    Solved!

    I took the code of this doc, deleted the reference EditField and adding a field to the constructor parameter.

    I then used the custom manager that results in place of the VerticalFieldManager in my previous code... using the fixed EditField as the field to the Manager constructor arg custom.

  • Problems with nested VM, EPT, 4.1 5.1 nested

    Good evening

    I'm having a problem getting material passthrough to work. I'm under 5.1 ESXi (free license) and trying to nest 4.1 (free license) on the inside. In the settings of 4.1, I tried setting EFA / IVR affecting hardware/EQUIPMENT, but also automatic. Both occur in the following message:

    Warning message about ESXi 4.1: virtualized Intel
    VT-x/EPT is disabled for this ESX virtual machine.
    You will only be able to run 32 bit nested virtual
    machines.
    I heard all kinds of things to get this working. This is going to manually edit the VMX (tried), to memory (tested), to set the automatic EPT parameter instead of solving manually (tried) locking file. The same result message. EPT is enabled in the BIOS and EFA is certainly feasible on this processor (E5-2650). Any ideas to get this to work? If you need logs, you can tell me where to get them? (I see some threads require vmware.log but discharge only I get from the vSphere Client is huge and made up of a gzip file and individuals in a folder)
    ESXi 4.1 VM under network adapters said that DirectPath IO is not taken in charge and one of the reasons for which it lists is that the host is not configured for this. I know that it is experimental, but I hope that something can be found for this.

    Thanks for the help!
    Sincerely,

    By using the web client, check the box 'virtualize virtualization to support', or edit the vmx file to add:

    VHV. Enable = TRUE

    Note that the virtual hardware version must be at 9.

  • Problem with the entire event looks like a bug

    Hello

    I got a requirement like this, there are two text fields Textfield1 and Textfield2 to say, and Textfield1 is full it should automatically go to textfield2 and fill the characters typed on the keyboard. I had this implemented using comprehensive event. If Textfield1 is full change focus to Textfield2.

    Now, I met a very strange question, i.e., the last character I enter Textfield1 won't Textfield2. His only full because is triggered to the key of the last character.

    I tried other alternatives did not work.

    Guys, now I do not understand is that true. Someone had the same problem.

    Thank you for all that you do.

    Yes, I used this script

    xfa.host.setFocus ("TextField2");   in my complete case. However, I could solve the problem by using newText and limiting the length to 50.

    Now I got a different question, that is, it does not work if I enter all uppercase the TextField1.

    Reason for the number of characters is different for upper and lower case. Don't know how to handle this.

    In addition, I expect to complete event can be a solution in this case, however if I use full event and you change the focus to new textfield the last key shot strays.

    Any help on this would be much appreciated...
