How to use a variable out of the nested < fx:component > tag?

Hi flex community.

I'm trying to reach the House of the label of the component variables. But I am still getting this error when I press the button:

  • How to use a variable to specify the color when you set an attribute

    Hello

    We use BI Publisher (OPE) embedded in the e-Business Suite. So we are actually on version 5.6.3.

    I'd like to conditionally set the cell background color attribute in a table by using a variable reference. something like this (the sense in which I tried):

    <? attribute@InContext:background-color;$exEmpBGColor? >
    <? attribute@InContext:background-color;' {$exEmpBGColor}'? >

    The 'standard' to do this way:
    <? attribute@InContext:background-color; '#CCCCFF'? >

    Can someone please help? (i.e. is it even possible?)

  • How to use a variable to browse the XML data

    My chart has xml data that looks like this:

    < getViewResponse >

    < month >

    "Dec".

    < NetIncome >

    etc.

    the following lines in actionscript work perfectly for the table:

    chart data provider

    _chartDP = new XMLListCollection (resultxml);

    The last argument of Colum graphic in DocumentElement.ColumnChart will change. I want to make this variable instead.

    I tried DocumentElement +'. ' + this. [ColumnChart] but I get an error telling me that the property does not exist.

    The following almost works:

    event.result.getViewWithTitlesResult.DocumentElement. *.

    but my card has a series of additional data empty.

    How can I adjust the latter to a variable?

    If the data that currently say you XMLList has a single point, just cast to XML with XML (myXMLLIST) or "myXMLLIST in Xml format.

    How to use windows search to search the contents of a bunch of files with random names / extensions? Plain txt files say 1,000 with random name of file extensions?

    You can always search within those, but you need to add extensions to the file system so that it knows to look inside these files.  You said that you have a lot, so it's perhaps tedious.  Here's How to search within several types of files.

    One thing you could try is rather to make a copy of this file, rename all the files to the same extension (even an extension false for example something.bill) and perform your search on this band.  Just an idea.

  • How to use substitution variables, as in Microsoft Word using Hyperion Smart view

    Can we use the Substitution Variables to copy data points and cool off in Microsoft Word? I tried and it does not dynamically (copy the data points only copies what was in excellent cell right there). It copies only the static value of this variable for this cell. I want to use dynamically in Word so that if I change the value of this variable in Essbase, it is updated in Word on refresh. Any idea?

    We need this notification feature in microsoft word and keep using data points every year (instead of copy the cells of excellent on new)

    Any help or suggestion is appreciated.

    Thank you

    You may not use substitution variables, as with the copy data points. I tried a while back (after 111.1.2.1.102) and it wouldn't work.  I checked with Oracle development and they said that I is not available

  • How to use setViewportBounds (Bounds value) to the ScrollPane?

    How to use setViewportBounds (Bounds value) to the ScrollPane? This method is, visually, what for? I tried to put a specific Bounds.minY to have a precise scrolling in the axis Y in vain. I use the setVvalue() method to scroll, but it is not convenient to exactly locate a position in the coordinates of the node content listed in the scroll pane.

    The viewportBounds are the limits of the viewport (i.e., the visible part of the content) in the scrolling pane itself, if I understand correctly. The way to access programmatically is by setting the vValue property.

    I have not tried, but if you do something like

    scrollPane.setVmin(0);
    DoubleBinding vmax = new DoubleBinding() {
         { super.bind(scrollPane.viewportBounds(), content.heightProperty()); }
         @Override
         public double computeValue() {
            return content.getHeight() - scrollPane.getViewportBounds().getHeight() ;
         }
    };
    scrollPane.vmaxProperty().bind(vmax);
    

    to configure your component to scroll, then you can call setVvalue (...) and just pass a location of coordinates for your content node. This assumes that your content node is a region or a control; you will have to perhaps a little logic in the method computeValue() to deal with the cases where the display window is greater than the additional content.

  • SQL how to use a variable and use the result as a reference for the name of the table

    Hi all

    I have new in the declaration of Oracle, sorry in advance if something is easy for you all. BTW, I have this scenario:

    I have a table OL structured in this way:

    Date - it contains dates, for example 11/01/2015

    TableName - it contains strings, for example, OL1, OL2, OL3 and so on...

    Then I have a different table, the name of these tables are of the same name in the table of the OL, so I have table table, OL1, OL2, OL3 table and so on. The structure of these tables is the same. And Yes.

    table OL1

    ---------------------------------------------------------------

    ID LAST NAME FIRST NAME PHONE

    ---------------------------------------------------------------

    1 JOHN DOE 12345679

    ID LAST NAME FIRST NAME PHONE

    ---------------------------------------------------------------

    1 ANNA KRAIG (NULL)

    NATHAN FRESHMANN 111111133 2

    If the scenario is clear, I would like to retrieve the value (null), research in all the OL * tables by using the value of the OL table (tablename) max.

    If I'm going to do these simple steps, I got the result:

    Select max (TableName) OL

    the result will be OL2

    # I know not how to use the option set to avoid changing the table name in the sql statement all the time.

    set mytable = 'OL2.

    Select Name, family name

    of & mytable

    When the phone is null

    Any idea?

    Thank you very much in advance.

  • How to use text variables and the Image for printing

    I work for several months on the product with AS3 Configurator.
    I am not competent with AS3.
    Now, it seems that perhaps my design is all wrong.
    Is there a good way to do this?

    I have a main scenario that has video clips showing images of different options for the product.
    On the first image, I use buttons to select the choice for option 1 of the Option1_mc.
    Can I store the selection in a variable.
    I use a button to go to the next choice (screen 10.)

    On frame 10, I use buttons to select the choice of option 2 in the Option2_mc.
    It is stored in another variable.

    There are about 10 options that are selected and stored in variables.
    Some are text values and other images taken from video clips Option instances.

    I made a Print_mc to use to printjob.
    I can't get the values of the variables to display the first image for printing.

    Any helpl would be appreciated.

    You are welcome.

    you will not be able to insert a variable into a textfield.  you are going to assign to the text of your TextField property set to one of your points of variables to.

    Thus, for example, if you have:

    var var1:String = 'this is a test ';

    You can use:

    TF. Text = var1;

  • How to use two different versions of the stub of Web Services SDK files in a single project (5.5 and 6.0)

    Hello

    I have a project that uses the vSphere 5.5 management SDK (I built the stub files according to the documentation) and have these in my c# Solution. Everything works beautifully. My class files that interact with vSphere all have a use statement as follows:

    using Vim25Api;

    All fine so far.

    Now, I want to be able to provide support for a user to connect to vSphere 5.5 and 6.0 vSphere environments. I built the stub files for vSphere Management 6.0 SDK and those in my solution presented in a separate project. Each project is based on a different class library and I have each set of files for each version of vSphere stub in different NuGet packages. However, when I select to use a vSphere 5.5 connection, it seems that internally the 6.0 files stub are used, or vice versa.

    I tried to separate things out by giving the Vim25Service.dll and Vim25Service.XmlSerializers.dll files for each version of alias names (alias by default for all assemblies is "global", but I changed it to vSphere5 and vSphere6 for each version. Then at the top of each class file before all with what I'm doing:

    extern alias vSphere5;

    or

    extern alias vSphere6

    (According to what project I'm in). Then, use the using statement for each class file that interacts with vSphere using vSphere5::Vim25Api; or using vSphere6::Vim25Api; to use the files to correct/stub namespace for each version I support.

    However this still doesn't seem to work, and things seem to be getting confused upwards somehow. I take a guess that internal files make calls and somehow have crossed.

    Is it possible to use two stub version of vSphere together different files in the same project? How should I handle my script? I thought of just upgrading to use the version of vSphere 6 (I can always connect to vCenter 5.5 using these, but some of the properties on the object have changed, (for example some dynamic properties on AlarmObjects and other items have been removed and code breaks if I delete the references to the stub vSphere 5.5 files.) So, I want to keep two different versions and use each of them separately in the same solution, so I support vSphere 5.5 and vSphere 6.

    Solved - this using wsdl.exe and just by specifying a different namespace to use in the proxy class that is generated by using the /n switch.

    for example using PowerShell to build automatically, the value $VimApi and do:

    WSDL.exe/n:$ VimApi...

  • How not to display variable binding in the query ADF search panel?

    Hello, I use JDeveloper 11.1.2.3.0.

    I have a variable binding in my VO, (* required) that I use in the sql query. I put the value of this variable to link through the groovy expression so I don't have to manually put through my page. It works fine but the problem is that it appears in the query ADF Panel that I created in my page. To do this, I created a ViewCriteria and I've specified to display only 3 (other) fields for the simple search. Apart from the selected 3 variable bind shows here again because its value is set. I tried to remove the ' * required ' of the variable binding in the original Version, but in this case I have problems with my sql query.

    Does anyone know how this variable is not to display in the Panel request ADF?

    Thank you

    Has tried to define the binding to bee hidden variable?

  • How to use batch files to deliver the payload of the ODC to AAU?

    Hi all.
    We are trying to do along this week and, so far, we could not understand how to use the batch files containing the option on the ODC and validate the output files to the University Complutense of MADRID.
    So, these are our specifications:

    We have opened a ticket with the Oracle Support for how we should do it. The number is 3-6108348211 SR.
    Let me try to explain what we want to do:
    1. we have a batch file with all the metadata for many files of UCM
    2. we want to use this ODC file, so the application converts the images and they are committed to the Complutense University of MADRID
    3. we should see all these files and their metadata, thumbnails and content associated with the Complutense University of MADRID

    5 so, when we use this command on the ODC file, the file (or image) is converted, all metadata attached and then sent to the Complutense University of MADRID.

    But we do not know how to make the link between the ODC and UCM. The Oracle Support says that it is necessary to make some adjustments. In the books I couldn't find info on how to do, just generic information or the use of the ODC.
    Is there a way (without personalization) to do? Can someone give us a step by step guide?

    Thanks for any help and advice.

    It doesn't really have much point which is good to UCM to ODC, given that the ODC is really an indexing tool to get content in Complutense University of MADRID and capture. Once the content is in the Complutense University of MADRID, it should be at its final location.

    Batch files are the property of the University Complutense of MADRID and have no meaning to the ODC. Import of the ODC server has the ability to read the meta in a list, which is similar, but not a
    "Batch UCM file.

    You can have IBR convert files directly in the University Complutense of MADRID, trying to use ODC to convert is redundant.

    ODC was out of the configuration of the box with the AAU.

    For this question: "but we do not know how to make the link between the ODC and UCM.»

    The documentation covers all this very well. what page of the documentation is misleading or causing problem you?

    The guide step by step would be the documentation of the ODC.
