Difficulty with returns control to the parents program after call asynchronous Subvi

I'm trying to set up a directory of context-sensitive help for one of my programs.  This is the first time I tried an asynchronous call and I can't seem to make it work properly.

The attached HelpDir.vi is the parent program that gives the user different help files to choose.  When the user selects a help file, its Subvi should appear.  I would like the user able to let this help file upwards and close the help directory or select another help file to upsimulataneously, if they wish.

The strange thing is that, currently, this vi works exactly as I want if I stress execution on, but works normally, the HelpDir.vi becomes unresponsive when we help files was loaded and becomes sensitive again once the help file has been left.

I set up the parent program with a structure of the event running asynchronous call and forget everything as in the example of the expedition to the France so I do not know why the program parent is not recover control after the launch of the Subvi.  Please take a look and let me know if you see what I'm missing.

PS, You may need to update both static references.  I don't know if they break when you send the code this way.

Thank you

Tim

Change your dialogues float instead of Modal.  Modal windows will always be on top.  In the changing Floating, then you can access the window of your main VI as well.

Performance highlight should substitute somehow the disorder of modal window.

    Question
    I want to record with < alt > < s > in the Exact program online. This function does not work. This is the first time I use this program with firefox.

    edit, escaped mod < s > in order to avoid the line through question

    A web page can be defined a "accesskey" for an item. Unlike IE/Chrome/Safari, who use the Alt key only, Firefox requires pressing Alt and Shift to activate the element. In other words, try

    ALT + SHIFT + S

    and see if it works.

    I don't know of any way to change this so that the change is not necessary. There may be an add-on?

    I use apex 4.2 as well as the pop-up skillbuilder.   The parent (p110) window opens a child using skillbuilders 2.0 popup.  The pop-up (p114) transmits a report worth (#VESSEL_ID #) after confirmation by the user.

    For some reason any and I'm sure it's a simple syntax that I am not contagious, when the user selects the #VESSEL_ID #, the appropriate confirmation message will appear, but the window close or change the value.

    The field #VESSE_ID # a a link URL:

  • referential integrity with a view to the parent table

    Is it possible to create a foreign key that uses a view as the parent table?

    CREATE TABLE one
    + (id NUMBER CONSTRAINT a_pk PRIMARY KEY, +)
    name VARCHAR2 (32));

    CREATE TABLE b
    + (name of the b_pk VARCHAR2 (32) CONSTRAINT PRIMARY KEY, +)
    address VARCHAR2 (32));

    CREATE VIEW b_view AS SELECT * FROM b;

    ALTER VIEW b_view ADD CONSTRAINT b_view_pk PRIMARY KEY (name) DISABLE NOVALIDATE;

    ALTER TABLE an ADD CONSTRAINT a_fk
    B_view (name) REFERENCES of FOREIGN KEY (name);

    "After issuing the last alter statement I get the error: ' ORA-02270: no unique or primary key corresponding to this list of columns.

    If I use just the table b of referential integrity, everything works. Is this just a limitation of the use of the view with a PK defined as disable novalidate? Is there a workaround to use the view?

    Thank you
    mcslain

    AFAIK, you can create constraints on views, purely for the sake of documentation.
    Sense: these constraints are never implemented, they must be defined using the NOVALIDATE keywords to DISABLE.

    And since these constraints, say the b_view_pk in your case, are DISABLED/NOVALIDATE, you cannot have a foreign key (ENABLED), which points to them.

    Pouvez have you a foreign key pointing at them is DISABLED/NOVALIDATE too, however.
    But I bet it's not what you want.

  • To run the Java program after logging

    Hi all

    I need to run a Java program after the filing of a document by a user.

    Is it possible to do?

    Any pointer and documentation to this will be really useful.

    Thank you and best regards,

    Hi Nitin,

    1 RIDC API Developer Guide - http://docs.oracle.com/cd/E10316_01/ContentIntegration/ridc/ridc-developer-guide.pdf

    2 jARs - idcserver.jar should suffice the need the other jars - idcloader.jar, idcupgrade.jar, jspserver.jar (these pots are available in the files of the installation itself - \Oracle_ECM1\ucm\idc\jlib)

    3. I was talking about DynamicPrefix example in the HowToCompoment. You can also get this installed separately if it is not installed yet. This component will change the AutoNumberPrefix for recently checked in content depending on the Type of content. The user can specify what prefix must be used for Types of content with a simple configuration file, and during the recording, the name content must be generated based on this prefix and a sequential number.

    The file 'data_access_environment.cfg' contains all of the data on what will be the prefixes for each type of document. You can add or edit this file, and changes will occur when restarting.

  • How can I activate the zoom pinch after calling preventDefault();?

    I created a chart in the edge animate which should work correctly on both the iPad and desktop computers. The html file that I create will be then fired in an iframe on a Web site as part of a larger page. I've included touch events and mouse for interactive elements, and most of the time it works fine on the desktop and iPads - except for when it is not.

    I found in my tests that sometimes a mouseOver/mouseEnter or even a click event fires despite my use of the e.preventDefault (); in my events touchStart or touchstart (I tried both). The behavior is not coherent enough for me to determine why this is happening so I have a solution for the moment - I've added preventDefault(); to touchStart in document.compositionReady:

    $(document) .one ('touchend', Function {}

    e.preventDefault ();

    });

    I understand that this is not ideal, but with deadlines and all that noise, it's the best solution I found to this day.

    It works perfectly, but as expected, it also disables the pinch zoom and pan. I don't care panoramic, but the zoom is necessary because the data points on the graph are on the small side. Can someone help me with the code, I would need to enable pinch zoom after call preventDefault()?: Or the conditional statement that would go preventDefault(); on a regular/single touch but not a pinch of touch zoom?

    I use v2014.1.1 to edge host CC on a Windows 7 machine, if it is useful.

    I cannot share my code because of the confidentiality agreement to my company, although if necessary I can probably model a simple sample - I'm hoping someone out there with more experience in the development of contact devices can point me in the right direction.

    Thank you!!

  • Need help with movie controls (specifically the reboot)

    Hi all

    Noob question, so bear with me.

    I have a site that loads a page with video playing on one of the pages.  I put it in place so that clicking on the button of the page starts the video and clicking on a button for a another page stops the video.

    However, instead of stop the video she just paused, so that when the user returns to the page with the video the video resumes where it left off, rather than restart.

    My site as a whole is a great movie clip, so each page is not loaded when we click a button - the content is just interpolated on the stage.

    Is it possible for me to have the control to stop the film playing (other buttons on the page) or to start playback of the movie (own page button) to have restart instead of the first image?

    Code for the start is really simple:

    content_mc.about_mc. MyVideo.Play ();

    and the judgment is:

    content_mc.about_mc. MyVideo.Stop ();

    Thank you.  I know I'm asking for the wrong thing because I left speechless Google results with what I ask, helps find the right way to do it is appreciated, even if I like a lot the way the site is designed so preferably not redo the whole site would be great!

    C.

    If you do not use a pause button so you can activate your flvplayback instance autoRewind property the flv file will restart from the beginning, whenever it stops:

    content_mc.about_mc. MyVideo.autoRewind = true;
