How to avoid the race condition critical in the event loop?

I'm having a problem of race in the structures of the event.  I looked through various discussions of the forum and have not been able to track down a solution.

In the attached vi (labView2015), if you type a new number for 'X', are not press entry, and hit then the "Go" button, then the old value of 'X' is used in the case of structure.  I deduce that it is a problem of race where after clicking on the 'Go' button has undertaken a task in the structrue event and also set up something in the queue to actually update the value of the variable.  Sounds good?

This is the simplest example I could do for this problem that has emerged in vi a lot larger and more complex.  Any help is appreciated.

With our thanks!  Devon

In fact, in addition to require a loop around the structure of your event, you must configure your events to the button GO to "Change the value" instead of "Mouse down".

I should have mentioned, but I put my business in my excerpt to change value.

  • How to avoid the event doubleclick on a datagrid scrollbars?

    Hello.

    I have a datagrid.

    I need a cliccking of doubleclick event on a data grid line.

    I activated the doubleclick event. It works fine, when the doubling of the user on a line, something happens! In my case, I open a modal window. Great!

    Now the problem:

    The problem arises when the user clicks in a short time on a data grid (horizontal or vertical) scroll bar. In this case, a double click event is dispatched.

    But his intenton is just to scroll the grid, not more.

    Please, note that the dobule click on a scroll bar is a well-known action that can be performed in all applications and operating systems.

    I neet the event 'double click' just on a grid lines of data and not on its scroll bars. Cliccking twice or more on the scroll bar, I just want to scroll the grid. How can they avoid to send an event?

    Thank you

    can't you just check the target of the double click event? If the target is an itemRender then do your thing, if not then don't

  • How to avoid the launch of Labview VI when he invokes in Teststand environment?

    Hi, friends.

    I am a student of teststand. I wrote a few screws by Labview. Now, I want to invoke in teststand environment.

    But when I run the sequence. LabVIEW automatically launches.

    How to avoid the launch of Labview when I run the sequence?

    Thank you.

    LabVIEW programs require a runtime engine. Under the TestStand configuration drop-down, select adapters. You can change the LabVIEW adapter to select the runtime rather than the development system.

    This should prevent the main screen of LabVIEW to appear, but you will not be able to change your LabVIEW VIs while they run of TestStand using the runtime engine.

    Thank you.

    I'm not sure that I follow what you're saying...  But it seems that when the VI is called, the LabVIEW Development software is started and you want to avoid this.

    If you create an executable file or a dll and that any call within TestStand, she should not call the development environment.  You must have the LabVIEW runtime engine installed on the target computer.

    For several years I used TestStand with LV, if my memory does not have to be precise.  I think that the above worked for me.  However, it seems that I remember something to have the LV code in debug mode, causing to open development environment... but it's a distant memory.    You do not use breakpoints where the LV VI is called, are you?

    Hello

    Captivate 9.0.0.223: HTML5 draft.

    I'm sorry to ask this question, it's a little old chestnut on HTML5 in Apple iOS and Android.

    I have searched on the internet and forums for a solution underway, but could not find something that works.

    The problem is how to avoid the PLAY button, which forces the user to click / tap on it, when the project is accessible on an Apple or Android system.

    Play_icon.png

    The project will be published on the internet for use on any Windows, Apple or Android device.

    I have no control over the Web server or devices that will use the people, so that any changes to the software server or browser is out of the question.

    I have tried both a plain HTML5 and a responsive project, but neither avoid the Play button. I put an example of 1 slide on these links.

    The bottom line is: ' is it possible to remove the need for the user to click / press the Play button?

    In your normal HTML5, there is a line (I think it's 46) with this code:

    Add cp.movie.play (); Located below.

    so:

    CP. DoCPInit();

    Hey, Malcolm.

    Best way to explain what basically rendering 3D correctly really takes a lot of time, haha.  So that you may be able to work with the real-time 3D model and make changes quickly, we use two different rendering methods.

    There is an "Interactive" mode which is not like the beautiful light/shade, but is very fast - and that's what you see when you interact with the default template.

    Then, there is a mode "Raytraced" which is much more advanced calculations and stuff to give you a proper lighting / shadow.  Raytraced rendered may take time if so we can not use it all the time.

    In order to get the lights/shadows appropriate you need to perform a path Ray would make on the document.  Best way to do this:

    • Select your 3D layer in the layers panel
    • Make a selection in the drawing area to the area that you want to make (I recommend to test rendering of area to check the lighting/shadows before committing to make the whole layer).
    • Push the button is rendered at the bottom of the properties panel (it looks like a cube in a rectangle box, right next to the delete icon).

    There are other things that you must do if you want to get the best image search quality such as the addition of secondary lights!  You can add more lights in the 3D Panel using the small icon of light at the bottom.  Have 2-3 stage lights and adjusting their colors can make a big difference with the Assembly of your character in the scene.  Here is a small image for some comparisons:

    You can see the image with two lights a look much more realistic lighting and shadows and raytraced of one and two versions are much nicer and cleaner!

    Hope that helps!

  • How to avoid the FDM-command being moved files from the OpenBatch folder

    Hello world

    I have a little problem with Batch Processing of the FDM - I need to stop the movement of files in the folder OpenBatch - when a batch is executed.

    The installer by using the Task Manager, a load a Batch Script and Script integration all works very well. However, the process must run every 3 hours, so I need the file "A_LedgerTransLocation_Actual_nov - 2013_RR.txt" to remain in the \Inbox\Batches\OpenBatch\ folder at any time.

    How to avoid the file is moved?


    Best regards
    Frederik




    PS: I noticed on the OTN Forum is it may be possible to script a solution such as:

    FSO1 = CreateObject ("Scripting.FileSystemObject") set
    Set File1 = FSO1. GetFile ("FDM Directory\FDM Application\Inbox\Batches\Openbatch\A_LedgerTransLocation_Actual_nov-2013_RR.txt")
    The BATCHENG value. PcolFiles = BATCHENG.fFileCollectionCreate (CStr (strDelimiter), File1)

    However this is not possible, as the controllers of the company need to edit the. TXT file themselves. They will not be able to edit the script too.

    I don't think you can prevent the FDM, move the file. I'm assuming that the file change in each period to use the last period of POV, so I think that option easiset to copy the file (based on a part of the name (location?) to a temporary location before began the FOM and write again later.)

  • How to avoid the link of a null value in a column of link

    Hello

    How to avoid the link of a column with the value zero. Is that the link should be disabled for the column with the value null, and it must be enabled for all that have a value.

    Ex

    DEPTNO NAME (link column)

    10 SCOTT
    20 MAC
    30 SMITH
    40         -
    50 SAM

    I don't want to link to the value null in the name column, but the name remaining should have link. Please help me.


    Kind regards
    Barro

    Hello

    One way is like this:
    1. create a column not displayed, called link_display in your report to return N or Y depending on whether you want the link by adding the SQL report:

        NVL2(name, 'Y', 'N') link_display 
    

    2. in the header of the region, define a class for the column name using:

    
    

    3. for the name column containing the link add link attributes: class = "" display_link_ #LINK_DISPLAY # ""

  • How to avoid the SORT operation.

    Hi gurus,

    Oracle version is 11.1.0.7

    I have a select query that has Row_number() over (Partition of col1, col2 order by col1, col2 desc nulls last) function to eliminate the DUP on these two passes.

    Here it costs 4639 for sorting. Now, I added a two other columns in the query Select (has not changed the Row_number analytic function).

    COST of sorting is now 555635.

    This sort operation may use Temp table space. How to avoid the cost of SORTING.

    Note: I use the function analytical only to eliminate duplicates on Col1 and Col2 only.

    How to sort takes a large part of the COSTS by adding only two columns in the select list.


    Any Suggestions...?


    Thank you
    Mike

    I would say:
    1 don't worry unnecessarily about the cost of sorting - do you know if you have a problem.

    2. in general, eliminate from the beginning, sort late (i.e. After you have eliminated all you can)

    3. If you are concerned by the outpouring sort on the disc then you could go to manual management of pga (assuming that you are currently using automatic) for this particular operation and override sort_area_size.
