How to access an instance of an object through activex

I try to retrieve data in real time to a FSA pressure mapping system and uses the activex of LabVIEW tools to connect.  I interfaced with hardware (can recover soap operas and others), but were not able to read real data.  The company programmers use Javascript for their programs and know nothing of LabVIEW.  Here is the info I got from them so far.  I'm reading an instance of an object through its activex reference.  Got out readings, I'm stuck trying to read an individual reading.  Thank you

The InterfaceModule.Read method returns an object Frame.  The framework
object contains a collection of one or more readings (Frame.Readings).
There is an indication for each sensor connected to the IM table. If
they use a single mast, then the reading will be in
Frame.Readings (0). Value of pressure of the probe is contained in the
Property Value of Reading (Reading.Value (column, row)).

So to take a read and retrieve the pressure for sensor A1
(column = 0, = 0 line):
...
Frame = im. Read();
pressureA1 = section. Readings (0). Value (0, 0);

Difficult to say without having the ActiveX library, but there is probably a method "Item" that will allow you to access a specific element in the collection. For example, with Excel ActiveX library you can get to a specific worksheet to the collection of sheets in a workbook by using the Item method, as in the attached photo. Note that you may need to convert the object returned in the appropriate type, depending on what is returned. For the Excel library the 'Article' method returns a Variant.

  • How to access the attributes of an object using TestStand. ?

    Hello

    I have a class named status in c# that has 2 data members. There is another class named parameter and it has functions that return objects of type status.

    I did the DLL from the parameter class. Then I added this class to NI TestStand and calls a function and this function returns an object of type status.

    Is there a way by which I can access the data members of the object returned in TestStand?

    Thanks in advance

    Yes, there is another alternative. If you state a value type (i.e. a struct in c#) then you can tell teststand to store it in a corresponding data structure TestStand rather than an object reference variable. It works even for the private fields in your structure. To do this:

    (1) first to report a type value and no matter what other changes are needed in your code to take account of this (value types are copied when it is passed by value to another method, if this isn't what you want you will have to pass by reference - i.e. the c# ref keyword).

    (2) recompile your assembly.

    (3) in the specification of module Panel TestStand .NET, you should now see a new button next to the expression for the return value of type status resembling TestStand data type icon. Press this button and it will prompt you to create a TestStand custom data type that matches the type .NET. Select this option to save the type in the type palette file MyTypes.ini. Just do it once. Once the type is in your palette file type MyTypes.ini it will be available then and you must only update if you change the type .NET.

    (4) create a local variable of the TestStand Custom data type instead of the object reference. Note that you can expand and see the properties under.

    (5) use this new local variable to store the return value of status. TestStand will be copy/update the properties of the variable to match those of the .NET structure that the method returns.

    NOTE: You can also simply store the fields of a struct in separate variables increase the return value of type status once it is a struct and specify a separate variable for each field instead of creating a custom data type TestStand.

    Don't forget that TestStand makes a copy when you store a struct that this way replaces the struct when this will not appear in the copy.

    Hope this helps,

  • How to access the instance property of the main class via child class

    Hi I hv done 3 classes objecthandler, box and nav

    NAV is child chass objecthandler, I hv make an instance of objecthandler box and now I want to access the property of box via NAV... See the code

    Class Objecthandler

    package code {}
    import flash.display.MovieClip
    import code.box
    import code.nav

    public class objectHandler extends MovieClip {}
    public var container: box

    Navigation = new nav()
    addChild (navigation)
    navigation.addEvents)
    navigation.x = 275
    navigation.y = 400

    container = new box()
    addChild (container)
    putcontainer ("default")< < works well here
    }
    public void putcontainer(page:String) {}
    Container.OpenPage (page) < < when this function is executed it returns ("page is open"+ page)
    }
    }
    }

    Class of NAV

    package code {}
    import flash.display.MovieClip
    import flash.events.MouseEvent
    import flash.display.DisplayObjectContainer

    galleryBtn.addEventListener (MouseEvent.CLICK, releaseFun)
    productsBtn.addEventListener (MouseEvent.CLICK, releaseFun)
    contactBtn.addEventListener (MouseEvent.CLICK, releaseFun)
    }

    public void releaseFun(event:MouseEvent):void {}
    putcontainer(Event.currentTarget.Name) < < showing the error over here
    }
    }
    }

    You should review your logic.

    It is not supposed have nav extend objectHandler and then has an objectHandler method that creates a new instance of nav.

  • How to access MC instance when we have only his name as a string.

    Hello

    I'm not good to the ACE, but I try.

    I'll send the instance (i.e. String) of the MovieClip to a function name.

    This feature, I need to access the same instance of MovieClip using this name.

    I have an Instance of MovieClip Planet_mc name. And I send you its abc() operation

    ABC (Planet_mc. (Name)

    function abc(s:String):void

    {

    do something to change the alpha of this instance.

    }

    Thank you

    of course, you can:

    ABC (Planet_mc. (Name)


    function abc(s:String):void

    {
    var Dragged:DisplayObject is getChildByName ("Planet_mc");.
    Dragged.Alpha =. 5;

    }

    Although it is still easier to use:

    ABC (Planet_mc);


    function abc(s:DisplayObject):void

    {
    s.Alpha =. 5;

    }

    I have a simple model of dam like that. I want that the variable 'id' in this class to return the identifier of object reference managed (as vm-101). Is there a special property name for ID?


    [Bindable]

    [Model(type="VirtualMachine")]

    SerializableAttribute public class VmDataItem extends to {DataObject

    public var id: String;

    [Model (property = "name")]

    public var name: String;

    [Model (property = "runtime.bootTime")]

    public var bootTime:Date;

    }

    You don't need to use a variable id, the object reference is already part of the DataObject class.

    sourceInfo_.provider is the IResourceReference of this object, then sourceInfo_.provider.uid contains the identifier you are looking for.

  • How to access settings/local/variables, who went through referenece?

    Hello

    I am new to NOR teststand.

    A single sequence file (file1.seq), I called another file of sequence (file2.seq), which I spent the value of parameter by reference (Locals.Driver)

    Parameter is Local that contains string variables.

    In File2, I want to replace the value of Locals.Driver.

    But I'm not able to access past variable reference (Locals.Driver) in File2.

    Please tell me how to use this variable in File2.

    Settings are accessible using "Parameters.variable".  If you pass by reference, you just put this setting and it will update the local section that allows you to call the sequence when the sequence is complete.

  • In the browser, how to access the tab bar without going through the top of the page active

    Sometimes, I like to browse a page with several links - like reddit-, open some links on a separate tab, read them and then return to the homepage to resume playback from the point where I was before.

    The problem is when I'm far down on the page, I scroll the way back to the top in the order to the address bar and the button 'show tabs' to appear. Is there another way to do this? Perhaps a gesture or a button hidden to show the sidebar with tabs?

    Hi felipekfcosta,

    Thanks for this suggestion, we do not have a way to get the tabs without scrolling to the top.

    But, we have a long-term plan to add something to the browser that allows you to drag to another tab, no matter where you are on the page. Please use Firefox OS and by sending your comments and questions.

  • A custom object to access class instance to the

    I created a few (TextInput, ComboBox, CheckBox) instances of the component (created as a public objects) in a Document class and added to the scene.

    Now, I created a class customized to a movieclip in the library and instantiated in the class of document (also a public proceeding).

    I need to access instances of the component in the custom class. How to do this?

    Also, it is advisable to use the ENTER_FRAME event frequently? because if I can't access the instances of components in the custom class above then I will remain no other choice than to use ENTER_FRAME event in the document class whenever I have to change a value in the components...

    So, is this a good practice?

    I think you're overloading the things why don't you just leave your document class adds a TextInput, and your button as his children? Then you can access both of them the class of document with ease.

  • How to access objects collection

    How to access the collections of objects for example ReportSections report? I can access ReportSection, but not his collection...

    Reference: http://www.ni.com/pdf/manuals/372844e.pdf

    Maybe you don't understand exactly what section of the report is. According to the help:

    Use this class objects to store, update and transfer reports. You typically use the ReportSection objects to avoid creating copies of a report that the report is transferred between the generator of reports, process, Report and ReportView control object models. You can create a new ReportSection object by calling the Report.NewReportSection method. ReportSection objects can contain other ReportSection objects.

    As a general rule, a process template creates and updates the ReportSection object and assigns to the report object by setting the Report.ReportSection property.

    It has a sub-property called ReportSubsections , which specifies a reference to the ReportSections object, which is a collection that contains a list of child ReportSection objects to the current object. Looking at this object, it's a list of items that you can index through to get each.

  • How to access the BitmapData instance on the class that extends the charger?

    Hello. I use Flash CS6 to create an AIR application that loads an image from the computer, and then a pixel counts using its bitmap data.

    MyImg is a class that represents the loaded image.

    package com.utils {}

    import flash.display.Loader;

    SerializableAttribute public class extends {charger MyImg

    public void MyImg (): void {}

    }

    }

    }

    In my main class I manage the selection of files and loading.

    private var _myImage:MyImg = new MyImg();

    private var _file:FileReference;

    private var _fileTypes:FileFilter = new FileFilter ("Imagens: (*.jpeg, *.jpg, *.gif, *.png)", "*.jpeg;") *.jpg; *.gif; *.png");

    When the user clicks on a "load image" button on the stage, it calls loadMyImg().

    public void loadMyImg($e:MouseEvent):void {}

    chooseFile();

    }

    The user then selects the file he wants to do.

    private function chooseFile (): void {}

    Inasmuch = new FileReference();

    _File.addEventListener (Event.SELECT, fileSelected);

    _File.browse ([_fileTypes]);

    }

    Once you have selected the file, it is loaded as a byte array.

    private void fileSelected($e:Event):void {}

    _File.removeEventListener (Event.SELECT, fileSelected);

    _File.addEventListener (Event.COMPLETE, fileLoaded);

    _File.load ();

    }

    When it finishes loading it loads the byte array in _myImage.

    private void fileLoaded($e:Event):void {}

    _File.removeEventListener (Event.COMPLETE, fileLoaded);

    _myImage.contentLoaderInfo.addEventListener (Event.COMPLETE, dataReady);

    _myImage.loadBytes (_File.Data);

    }

    Once it's done I try to use the _myImage BitmapData, but cannot...

    private void dataReady($e:Event):void {}

    $e.target.loader.contentLoaderInfo.removeEventListener (Event.COMPLETE, dataReady);

    trace ($e.target + $e.target.content + $e.target.content.name + $e.target.content.bitmapData); Returns [object LoaderInfo] [object Bitmap] instance 155 [BitmapData object]

    trace (_myImage + _myImage.content + _myImage.content.name + _myImage.contentLoaderInfo + _myImage.contentLoaderInfo.content.name); instance of [object LoaderInfo] 155 155 instance [object Bitmap] returns [object MyImg]

    trace (_myImage.content.bitmapData) //compiler error: 1119 of bitmapData property possibly access not defined through a reference with static type flash.flashDisplay:DisplayObject.

    error //same trace (_myImage.contentLoaderInfo.content.bitmapData)

    }

    I don't understand what I'm doing wrong. Instances have the same name so that they are identical. They both trace as bitmaps, yet when I didn't access it from the event I do not get the bitmapData. Can someone tell me what I am doing wrong? I need to use the bitmapData of the classroom MyImg. I guess I could create a BitmapData variable in the class and give it the value of $e.target.content.bitmapData, but I still want to know why it can't be simpler.

    Thank you!

    Cast _myImage.content as bitmap:

    Bitmap (_myImage.Content)

  • How to remove all the scripts on the instances of the object?

    I'm looking for one any solution here, not to mention disabling the setting warn.

    I hate it when I am converting someone to another project AS2 AS3 and buried on an instance on stage somewhere, that gives me the warning code:


    "The actions on the button or MovieClip instances are not supported in ActionScript 3.0." All the scripts on the instances of the object will be ignored. »

    How can i:
    Has) find what instances have code on them.
    or

    B) delete all of the code on all instances.

    Idea:
    Can I save as a different format/version/something and lose data in some way. Then I could convert back the current format of the FLA?

  • How to access info child movieclip to an object in a table?

    Hello

    I created a whole bunch of clips dynamically.

    I gave a name based on a variable number to each item:

    MC. Name = "mc" + i;

    I also use addChild to add some dynamic text fields to each movieClip and named myText1 myText2.

    Then I push each movieClip object in a table:

    myArray.push (mc);

    When I have the movieClips addChild, they display fine, complete with each textField.  And if I use the following loop to find the name of each element of the array, I get:

    for (var i = 0; i < myArray.length; i ++)

    {

    trace (myArray [i]. (Name)

    }

    output:

    MC1

    MC2

    MC3

    MC4

    etc.

    What I want now is to be able to access text fields in each movieclip in the table.  However, I get errors when I try in different ways.  For example:

    for (var i = 0; i < myArray.length; i ++)

    {

    trace (myArray [i].myText1.Text);

    }

    gives error: a term is undefined and has no properties.

    How to access the values and the content of the children of the movieClip objects that are stored in the tables?

    Thank you

    Shaun

    For some reason, dynamically added children cannot be targeted like that.  If you have added the textfields dynamically, you may need to use the getChildByName() target.  It depends in part on how you created and whether or not you have direct access to them.  Aside from that, you can also assign the textfields to the variables that you create for the mc and target those who by their names of variables.

    These two approaches demos the following:

    var mc:MovieClip = new MovieClip();
    addChild (mc);

    var tf:TextField = new TextField();
    TF. Text = "this is the text";
    mc.addChild (tf);

    first way

    TF. Name = "tfield."
    trace (TextField (MC.getChildByName ("TField")). (Text);

    second way

    MC.tfid = tf;
    trace (MC.tfid.Text);

    You can also store the textfields in the tables are created and they have direct access to them with the need to target the mc... the index must be the same as the one you use for the mc anyway.

  • How can I access all instances of the itemRenderer in a specific DataGridColumn?

    How can I access all instances of the itemRenderer in a specific DataGridColumn? Or, if I have a rowIndex and columnIndex, how do I get the itemRenderer to these clues?

    I use States to change the display of my itemRenderer of a TextField of a PopUpMenuButton. What I was trying to do was change back the display of all the other itemRenderers visible in the column of the textfield, when one of the itemRenderers displays the PopUpMenuButton.

    I tried to loop through all of the itemRenderers in the column and casting them as the class I was using and then by setting the currentState, but, it wasn't good performance wise and required too code. I simplified it listen to a change on the listData owner event (in my case a DataGrid, but any component ListBase) and by setting the currentState to null when it is triggered. Works like a charm.
