Tab control sequence

Hello

I learn LabView and until I started to make applications I couldn't see how complicated it is.

I tried to make VI to choose in the order of the parameters. After several attempts to solve the problem, the VI it works badly all the time. Could you give me some ideas how to do this? What architecture you choose?

The idea is:

-After starting VI Page1 is visible and active

-When the conditions for Page1 are correct, we could push the next button and go to the next page

-Page 2 is visible and active, and so on

-When we on Page4 (should be called "Summary"), this summary page of ist, which I prepare yet

-at any time, we should have the ability to go to any page using the tabs

The problem is:

-the following buttons are dimmed when I select the previous page

-There is a problem with reliability, sometimes I push the next button and nothings happen or page is visible but not active

I welcome all suggestions.

Concerning

GerdW has a very good point. You can move the structure of the event outside the structure of the case. Also, having a while loop within another time loop is not indicated.

If you have, it's just an event structure and a structure of cases, all within a single while loop. And with the structure of the event to the outside of the structure of the case, you might have a thread that changes States and not a local variable (it is recommended to use those when you have no other choice, because not using them can save you a lot of headaches when it comes to flow conditions and race data).

What I would use for such an application (and I would try to make it more modular as possible), is the architecture of producer-consumer, given the structure of the event in the producer and the structure of matter in the consumer. Something like this. You can also find some examples of programming HMI LabVIEW examples Finder, under Create User Interfaces

Kind regards

    Hello

    Purpose a documentation exercise, I wish I could) 1 load a VI by program 2) determine if the tab control is present, if yes how many tablets and if it has a built-in tab control sequence sequence 3) thanks to tabs, snap the front (FP) and the icon 4) and repeat until done.

  • Tab control acts like it is off but no

    I have a tab control that has ceased to operate at run time. It acts like it is off when turned on. At the time of editing, I am able to click on the tabs and they change visually. When I run it, by clicking on the tabs does not change tabs.   I reduced the vi to a simple loop with a delay of 200ms and the tab, with nothing else. The controls on the tab is the only thing in vi.  I made sure that the tab is enabled in the Properties dialog box. I noticed a strange thing: the Navigation tab button (in properties), it is all grayed out.  Once again, the control tab in in fact active, but it behaves as if it was not. I tried to recompile. Is there another setting? Why key naviation is grayed out? I'm using LabVIEW 2015.  Thank you!

    Yes it is a feature I've wanted also over the years.  Here's the first result that I got from the exchange of idea, but I think that there are duplicates autour.

    Basically, you can't do nativly but you can trick it work for you.  You make a tab that is false the user interacts with, changes to the value of another tab that things in it and then you fix every thing you want it is in the tab where it is demonstrated.  This works well if the thing in your tab is an element able to evolve to adapt to it, but if in a tab, you have a chart and another you have a bunch of buttons that should not change, then you will get a strange behavior.  You can tell the chart is more scope to this component, but then you lose the 'ladder while resizing objects' that make a lot more native user interface research.

  • Tab control: chart automatically resets when I switch between tabs

    Hello world

    I'm having a problem with a user interface. : mansad:

    I use a tab with two tabs control to switch between the two graphs. A graph shows data from a production machine (tab 1), the other a data from a measuring probe (table 2). Now, when I switch from tab to tab 2 1 and return, graphic of tab 1 is empty and begins to show the data from the moment of return too tab 1. Tab 2 data are not reset, but are constantly updated, even when the 1 tab is open. I'd like to tab 1 to behave like tab 2. It must be constantly updated even when tab 2 is opened and the data should not be reset after between tabs.

    Making machine is connected via a server (Data tab 1, Figure 1), the data from the probe are written a queue and comes from (Data tab 2, Figure 2). It's all part of the main VI. This part is shown in Picture 3. Here, historical data are reset to zero when the program ends. But I can't understand why it does not work as I want.

    Can anyone help?

    Thank you!

    OK, there are very strange things happening here, in addition to the problem you are having (which, I admit, I don't see yet why you have a problem).

    First of all, I've never met such a structure of strange and deeply nested directory for LabVIEW code as what you posted: Users\AB\BC\CD\DE\EF\FG\GH\HI\IJ\.  Why in the world you have an empty stack of sense files / directories to go?  Very, very strange.

    You view multiple charts using waveform graphs.  Do you, indeed, assemble an array of waveforms to display on the chart, but the waveform consists of a single point, 'built' in a table, with a current timestamp as t0.  Instead of going to all these efforts, you can simply group your data points in a Cluster and show that.  Your X axis will not display "Time now", but if you know the sampling frequency, you can adjust the X scale so it displays 'Time' in practical (such as seconds) since the beginning of the sampling units.  Note that you already have one such cluster (at least in the reading process data - the data output Process value - which can be connected directly on the diagram of fluid bed without the need of the Signalverlaufsdiagramm).  It could, in fact, "fix" your problem (but I'll let you test this).  You will need to do a similar Cluster Bundle in sight Parsum data and output the cluster instead of the table in order to test this idea.

  • Inexplicable delay between the evolution of the tab control pages

    Hello dear OR Forum.

    I have a strange problem.

    In my program, I use a tab control.

    On a change in the pages of pc immediately once the user clicks on the other page, but on another pc it is delayed (approx. 1 second) until the new page is displayed. The rest of the program works with the same "speed".

    You have an idea why this happens?

    The main program includes a while loop with a delay of 25ms. In the loop, there is a case structure, cases are different pages of the tab control.

    (it's the same exe file)

    Thank you.

    Tabs changing pages require a screen refresh if at least the graphics adapters could make all the difference.

  • Customizing a tab control

    Hi all

    I am trying customize appearances of controls for my application and have been involved in some of the custom themes user interface on the Web site of NOR.

    I am now stuck in the tab control - when I open up the control editor and add a tab control and then go to 'Customize Mode', I'm not able to get the typical menu if I right click on the tab control. The typical menu for other controls include options for "Import picture from the Clipboard", "Import a file", etc.

    After that I watched the themes custom user interface on the site NOR even once, as themetal Themeand OR themeand realize, they do not have the tab control so.

    A search of the forums also revealed a thread here, dating from a few years back, about not be able to use the tab control in a custom control.

    So my quesstion is, the tab control still not able to be used as a custom control? And is there a solution?

    Best regards

    Victor

    It works fine for me in 2011.

    The method I use is to drop the tab on the front panel control.

    Make it a typedef

    Click EDIT > IMPORT the IMAGE TO the Clipboard

    Import the image we want for the tab

    Then right-click on the tab of interest

    ADVANCED > LAYOUT TAB > IMAGE ONLY

    Then right click on the new tab

    ADVANCED > LAYOUT TAB > IMPORT THE IMAGE TO THE CLIPBOARD

    If this method does not work for you, please let me know and I'll see if I can get access to a 2010 machine to try it myself.

    Kind regards

  • does not by default the tab control in LabVIEW 2009

    I have a tab control in my LabVIEW program. I put the default value of the three page tab control. In older versions of LabVIEW, when the program opens, it opens with the display of page three. Prefect! But now in LabVIEW 2009, it opens to 1 page view. I tried to adjust the default time and again, but it is enough to open with the display of page three. Looks like it's broken in LabVIEW 2009. (I know that I can get around that, but apparently botched when the program opens on page 1 and jerks on on page three.) And change the order of pages would break the code. I don't do that.)

    To make the solution more smooth, you can uncheck see the façade when called property of vi and show it programatically after that you put on page 3.

  • typedef enum typedef to the tab control

    I have a typedef enum that defines that the DUT is for my automated test device. This enumeration is used everywhere in my code to determine which tests to run and how to interpret the results, etc. I also have a (much indicator tab to be precise) typedef tab control that has a page for each of the ESA with various indicators for each test that will be carried out on it must HAVE specific.

    I would use the typedef enum to select which page of the tab indicator to display. I am able to do it with brute force just a U32 converter like this:

    But would prefer to (because of my anality) eliminate dotting ugly coercian red (and depending on the size of the code, all memory that I can save help too).

    I tried many things, and none seems not to work. In this way, using a type cast, does not work.

    And not that this using variants (although it works with this little piece of the code example, maybe because my test set-up is an executable?):

    With the variant version, my test fixture survey an error 91 indicating data types is not compatible.

    Anyone has an idea how to convert between these two without which dot ugly coercian?

    Why not write a little VI with Enum entry and exit of the tab? It should be just a case internally structure. You can do the small icon so it does not much more space than the U32 conversion.
