Calling functions in a component before the component UI is used?

I know this has been asked before, in fact I'm sure I've had this problem and resolved it in the past. However, I can't recall the solution off hand.
I have a component, which contains a publich function and data. The component has a UI which can be loaded by another function call. Loading the UI works fine, and after its been loaded (and close) calling the first function works fine. However, before hte UI has been loaded calling the function does nothing.
Any thoughts?

Load the UI earlier but set the visible and includeInLayout properties to the component to false.
Then in the function call that used to load the UI, just set those properties to true.
If this post answers your question or helps, please mark it as such.

  • How can I build an application that calls functions in a dll if the associated hardware is not present?

    I am trying to build an application that use the "Call Library Function" node to call functions in a dll.
    The dll was provided by a third-party and includes functions to drive an I2C communication board.
    The problem I have is that the dll does not not properly because the hardware is not present.
    Therefore when I load the VI a broken arrow is displayed and when I am not able to build the application.
    I will not be running the application on the PC where I build the application, therefore I want to be able to build the application on a remote PC that has not all the hardware installed. Once the application will be build it will be installed on the target PC that has all the hardware.
    How can I make the application builder to build the application event if the dll is not properly loaded? (the dll will be properly loaded on the target PC)
    I want to do this on LabView 5.1.1, any ideas?

    Some .dlls don't try to attach to the driver when loaded.
    I've worked with both and unfortuately, I've not figured out a way around this problem.
    You could possibly use the Conditional Disable structure around the dll calls so they would not be loaded unless you're in the runtime engine. But i've not tried this so I don't know for sure if it's possible.
    Anyone??

  • I have just upgraded to OS X Mavericks. It wanted me to upgrade my 20000 photos before the New iphoto could use them. I did. 43.6GB of photos became 1.8GB of very small photos of arounf 178KB instead of 2.5MB. Can't do anything with them. Help?

    The obvious and simple solution is to restore from the back up you made before upgrading.
    Other than that you'll need to give us a lot more detail. Mavericks doesn't ask you to upgrade your Photos, upgrading to a later iPhoto asks you about upgrading the Library. Where is the library? What version were you upgrading from? Anything else you can tell us that might help understand the problem you're having.

  • Call Function From MXML Component

    I am using MXML to create components that I use within my
    application. I have one MXML file that contains a list with a
    custom itemRenderer that is in another MXML file. I have an
    actionscript file with a function that I want to call from the
    itemRenderer.
    If I call the function from my main application, everything
    works fine. If I try to call it from one of the other MXML files, I
    get a 1180 Call to a possibly undefined function error.
    Is there a special way that I need to use to call the
    function?
    The main MXML file is in the root directory, the actionscript
    file is in a folder called functions, and the MXML files are in a
    folder called components.
    Thank you for any help.

    I was able to figure out my problem. It was just a simple
    typo of including the wrong file in a Script tag. However, this
    caused more issues and I ended up having to rewrite a large section
    of code to get everything working.
    Thank you for your help.

  • Call function which only exists in the target system

    Hello,
    I have to call the function module BAPI_QUOTATION_CREATEFROMDATA2 from a BI system. Of course, the function module does not exist in the BI system. My problem is now how to create the necessary parameter types for the function call?
    I found out that the function module RFC_GET_STRUCTURE_DEFINITION returns me the complete definition for the necessary types but how can I transform this information into a field-symbol or something similar?
    Or is there perhaps a different solution which is easier to implement?
    regards
    Thomas

    Hi
    I think so, but I believe you don't need all structure, so you could define only structure you need in your program, it's probably faster than to manage dynamically many structure.
    Anyway you can create your structure at runtime by field-symbols, there are many post about this argoment.
    This is the last:

  • Call function from pl/sql when the name of funcion is in variable

    Hi,
    is it possible to do the following:
    I want to call (excute) a function within a pl/sql block, but the problem is that the name of the called function is stored in variable (is got as a parameter to mine pl/sql block).
    let's imagine:
    DECLARE
    name_of_function varchar2(10);
    result number;
    BEGIN
    result := ???name_of_function????;
    END;
    thanks for any suggestion,
    valer

    thanks for answer this exactly what i need.
    as i learned EXECUTE IMMEDIATELY does invoke pl/sql block dynamicaly.
    I tried it for invoking procedure. it woked fine. But not for function.
    So, does it work also for invoking FUNCTIONS ?

    My phone is having a lot of probably with the proximity sensor. Is there a fix? I am on a call and I can see the screen is still ON,even though the phone is pressed agaisnt my ear.
    I called applecare about this BEFORE the press conference today, just in case they choose not to assist users without previous reference numbers. I hope they don't do that.

  • Call function in itemRenderer component?

    I'm doing this exercise to help me with learning flex and
    have been using parts of
    Example:
    modifying data in DataGrid control from Live Docs.
    I want to be able to alter the appearance of specific
    DataGrid cells whose data has changed and am struggling a lot with
    it.
    The code is much the same as that example, but I have created
    a component as an itemRenderer for the first name column, linked as
    follows;
    <mx:DataGridColumn headerText="Some Title"
    itemRenderer="cpnts.irender"/>
    The code for this component is;
    <?xml version="1.0" encoding="utf-8"?>
    <mx:HBox xmlns:mx="
    http://www.adobe.com/2006/mxml">
    <mx:Script>
    <![CDATA[
    public function testFn():void{
    this.setStyle('backgroundColor','#BBBBCC')
    ]]>
    </mx:Script>
    <mx:Label text="{data.first}"/>
    </mx:HBox>
    in any hard coded form for now, how could I call the testFn()
    function in the first cell in the table, from the Application?
    What I'm working towards is a DataGrid used with data which
    changes live, each data cell would go green or red depending on if
    the value increased or decreased for example.
    Thanks in advance, please also let me know if this is wrong
    approach for doing this. Should I maybe be handling and comparing
    changed data in my ArrayCollection and setting other properties
    accordingly? eg: @change[none|higher|lower] then re-populating the
    DataGrid and setting display properties for each cell according to
    that value?
    Thanks again, (I hope I'm making sense by the way, I'm a bit
    low on sleep!)
    Jamie Mason

    Override the data setter.
    override public function set data(value:Object):void
    if(value != null)
    this.setStyle("backgroundColor","#BBBBCC");
    super.data = value;
    }

  • Call function outside of component?

    Hi,
    How can I call a public function that lives outside a
    component?
    I have a "Main.mxml" file that is set as my default
    application. In this file I have a public function called
    "switchView(). I also have another mxml file called "LoginView". I
    want to call the public function in Main.mxml from LoginView.mxml.
    Does that make sense? There are certain functions I want to be
    available across the board to multiple components. I prefer this
    method if possible.
    Any help appreciated

    you can make it static if possible and do a
    Main.switchView(); otherwise, Application.application.switchView()
    Please note this is just off the top of my head! I might be
    wrong here.
    A better would be to raise an event and let your main default
    application handle this event and do whatever is required instead
    of making them dependent on each other.

  • ITunes doesn't launch before the last automatic update using the OS X.

    The software error box requests to mark the 32 bit mode on its information window, but that option doesn't exists... So, what's up? How to fix it and how to allow the OS to never have this kind of mistake anymore??? (becouse it reminds me the win-bugs)

    I have the same problem, and it wasn't solved by re-installing Mavericks. After a reboot, the first time I try to start iTunes it takes a long time starting up, but then shuts down without ever showing a window. After that, it immediately shuts down upon launch. I'm running iTunes 11.1.3. I tried re-installing iTunes only, and tried re-installing Mavericks, but to no avail.
    Anybody any ideas?

  • How I can call controller's functions from another component?

    Hi again!
    I make a few web Dynpro components, for example first for user-data processing, second - for project-data processing. In the controller of 1-st controller there is a function getUserById(). In the controller of 2-nd component I need such function. And I don't want to make a dublicate for this function in the controller of 2-nd component. Is there a way to call function in one component from another?

    Hi,
         Yes, you can reuse the component. There are two basic types of component communication. 1. Intra Component communication 2.Inter Component communication.
    1. Intra Component  communication: The two components must be in same DC(project).
    Procedure:Say there are C1,C2 components in a DC.
    Open C2, Open interface controller, create a similar (_parameters and return type_) method to the method C2. Call C2's method in this Interface method.   
    Open C1, select and right click  Used Web Dynpro Components -> Add Used Component. In the wizard, you can browse and select the C2 component,and enter a name to the usage. Then the usage of the interface <b>must </b>be added in properties required controllers of a view/component controller.
    Now we can use the method that is available in the C1 interface controller.     
    You must define method before declaring usage
    <b>2.Inter Component  communication:</b> The two components are in different DCs
    Open DC metadata of C2. Right click on Public part-> create new Public Part.Enter name-> Next -> Select entity type as Web Dynpro Component in wizard,in Select Entities  select the component ,Finish.
    A structure for public part is created.
    Open C1, Open DC metadata of C1. Right click on Used Dcs-> AddUsed DC. Browse to C2's public part.
    Select Finish.
