How to access id property

I have created my own class NoCacheService in AS-3 that
extends httpService. It works fine. I invoke in a .mxml file via:
<utils:NoCacheService id="xyz" url="/url/here"
resultFormat="e4x" result="resultHandler(event)"
fault="faultHandler(event)" />
Now, I want to display some error messages from functions
within the NoCacheService class that include the id. I assumed this
would be trivial. Something like this.id + "error message". But
no....
I am new to flex, so must be missing something obvious. How
to do I access the id property given in the mxml component
declaration from within the actionscript?
Thanks!

I understand your point, but my new class is defined in a .as
file, not a .mxml file. I've attached the NoCacheService class just
to be clear.
The attached code will not compile. Each instance of this.id
generates the error:
"1178: Attempted access of inaccessible property id through a
reference with static type"
Thanks!

How to access custom property for attribute and control in .vm file?

Hi,
I have created custom properties in OPM for attribute and apply also that properties to attribute.
But if how to access that value in .vm file?
I accessed using
$attribute.getProperty("ScreenProp", "default value")
but it's not working but same is worked for screen custom property

$control.getProperties().get("PropertyName") works for custom properties on a control
If you output $control and $control.getProperties() to the html you can lookup the API for the used classes.
I can't give an example of the html because it's stripped in this forum

USB (Raw) - How to access VISA property: USB Bulk-Out pipe?!?

I'm trying to use my own USB device. Since I'd like to use more then one USB In/Out Endporint I need to change that Atribute in NI VISA using LabVIEW (afaik. NI VISA uses the lowest Endpoint Number as defualt).
According to LabVIEW 7.1 Help > VISA > I/O Session there is a VISA property which should be accessible via VISA Property node. That Property should be SUB Settings:USB Bulk-Out Pipe and USB Bulk-In Pipe.
Hoewever when schaning through the available properties I only get the following 4:
USB Intfc Num, USB Max Intr Size USB Port, USB Serial Num
How can I cahnge the Property USB Bulk-Out Pipe ?
Thanx,
Rainer

Thanks a lot - I knew it must have been some stupid small detail I didn't know ;-)
Thanx,

How to access a property in a static vi reference

Hi,
I'm completely new to Labview and I'm working on a project that includes controlling CANalyzer from LabView by an ActiveX control.
In CANalyzer I have a CAPL function that I need to call from LV. The problem is that the function must be created in the onInit event when starting a canalyzer measurement. The only way I have found to create the function is to use a "reg event call back" and create the function in a "static vi reference". This works and I can call the funtion from that vi, but I'm not able to call the function from anywhere else but from the "static vi reference" and since it must be strictly typed I can not add any output connector where I can add a reference.
I've been trying to solve this for thee days now and it's starting to feel hope less.
In VB the complete code would look something like:
    Dim WithEvents gCANApp As CANalyzer.Application
    Dim WithEvents gMeasurement As CANalyzer.Measurement
    Dim gSendFunction As CANalyzer.CAPLFunction
    Dim Y
    Set gCANApp = New CANalyzer.Application
    gCANApp.Open ("C:\...xxxx.cfg")
    Set gMeasurement = gCANApp.Measurement
    gMeasurement.Start
    gSendFunction.Call
   'Measurement OnInit event handler
   Private Sub gMeasurement_OnInit()
       Set gSendFunction = gCANApp.CAPL.GetFunction("MyFunction")
   End Sub
This would work fine since I have a reference to gSendFunction in my main code.
My LV code looks like this:
and my static vi ref looks like this:
What I think I need is a reference to the data thread coming from "GetFunction"
If any one can help me solve this I would be very happy!
Best Regards
Henrik

Hi,
you could add another input to your static vi ref where you input the reference to a reference display element which sits in your other vi (upper image).
Then you could make a signaling value change to the reference display element from within your static vi ref.
In your other vi set up an event structure to detect the value change. In that event close the vi - this will let you have the desired reference as output of that vi.

How to Read a Property called "due date"

I want to create a AppleScript that reads the to dos in the Today list of Things and display a Growl message which works but then I wanted to put into the title the due date. In the the 'Open Dictionary" for Things' To Do class there is a property called 'due date'. But when I try to read it out I cannot compile the script:
set taskDueDate to due date of taskItem
I get this dialog box error:
Syntax Error: Expected end of line, etc. but found class name.
and the cursor ends up on the 'date' token.
Any idea how to access that property?
Thanks - Andy

I added this line but it did not work for me either.
Here is the entire script (which I have taken from the Things wiki):
-- Checks to see if GrowlHelperApp is running, then registers this script with Growl
tell application "System Events"
if application process "GrowlHelperApp" exists then
tell application "GrowlHelperApp" to register as application "Things" all notifications {"Reminder"} default notifications {"Reminder"} icon of application "Things"
end if
end tell
tell application "System Events"
if application process "Things" exists then
tell application "Things"
set todayTasksCount to (count to do of list "Today")
set todayTasks to to dos of list "Today"
end tell
if todayTasksCount is greater than 0 then
set fullTaskName to ""
set fullTaskTitle to ""
repeat with taskItem in todayTasks
set taskName to name of taskItem
set fullTaskName to fullTaskName & "; " & taskName
set taskDueDate to current date
-- get due date of to do 1
set taskDueDate to due date of taskItem
set fullTaskTitle to "Reminder: " & taskDueDate
-- tell application "GrowlHelperApp" to notify with name "Reminder" title "Reminder" description taskName application name "Things" icon of application "Things"
tell application "GrowlHelperApp" to notify with name "Reminder" title fullTaskTitle description taskName application name "Things" icon of application "Things"
end repeat
end if
end if
end tell
Let me know if you have any ideas.
BTW I use AppleScript Editor 2.3 (118) and AppleScript 2.1.2.

How to access the Requirements property (& subproperties) of steps and sequences with the TestStand API

The concept of associating teststand objects to unit requirements for traceability purposes was added to TS 3.5, and I need to find out how to access the array of strings used to store unit requirements in step objects, sequence objects and sequencefile objects. The teststand help file points out that the requirements list of a sequencefile object is accessible using the PropertyObjectFile interface, and also points out that Requirements is a property of the sequence and step classes. Furthermore it implicitly states that the requirements property has a Links subproperty which is an array of strings, but that is pretty much the extent of the documentation on this new feature so far. There seems to be no expression function available to get to those requirements either.
I know that this feature was added to allow TestStand to interface with RG, and I am planning on using RG, but I would also like to do things with the requirements information within TestStand.
Anyone?

Are you talking about the Requirements Gateway? It is a separate product from NI that will do what you are looking for. I haven't used it so I am not sure of the API chain to make it work. Take a look and see if that is what you were thinking of.
Hope that this helps,
Bob Young
Sorry, I just re-read your original post and see that you are looking to also use the Requirements Gateway, so you obviously know about it. I don't know what the API changes were that made it work so I am not going to be much help.
Sorry about posting before getting the correct information from the original.

How to read a property in XSL?

Hi
I am trying to access a property in xsl and then invoke a service if the property value is set to true.
Here is what I have done until now:
1. Create a Normalized message nm
2. Set the property: nm.setProperty("ABC", "TRUE")3. nm.setConten(message)4. request.setInMessage(nm)5. send(request)Now I want to access the property in xsl to test a condition, how do I do this? Please help me;....

i dont remember from the top of my head + i'm falling asleep. but.. try this
IPortalComponentContext ctx = componentRequest.getComponentContext();
IPortalComponentProfile profile = ctx.getProfile();
String value = profile.getProperty("propertyID");
componentRequest is avaiable in JSP just like the response object. You need not to instantiate it.
getProperty("propertyID") is used to retrieve whatever propertyid you have in your portalapp.xml for that particular component you are executing.
goodluck

How to access checkbox in mx:list

I'm trying to access the checkboxes in my list
<mx:List itemRenderer="mx.controls.CheckBox" x="0" y="153" id="listVocab" height="297" width="313"></mx:List>
but I can't find a way. This is what I'm doing
        for(var i:int = 0 ; i < listVocab.numChildren; i++)
                if ( I want to access the checkbox here to see if it's checked then do the below but I don't know how to access the checkboxes??? )
                // This gives me access to the text but
               var word:String = listVocab.dataProvider[i].toString() ;

Problem is with dataProvider your assigning to dataGrid is of type Array of Strings so thats why its saying selected property is not available on String.
Code given above by me will work for arrayCollection having objects of following type instead of just plain strings:
public class CustomClass
         public var data:String; // here id you can store
        public var label:String; // here word you can store
        public var selected:Boolean;
You can make modification to
public class CustomVocabulary
        public var sentence:String;
        public var type:String;
        public var dbId:String;
        public var words:ArrayCollection; // this will contain objects of type CustomClass.
<mx:List id="list" dataProvider="{ customVocabulary.words }"

Error #1009: Cannot access a property or method

Here's the context of the problem, in which I will try to include as much information as possible while keeping the explanation brief.
I am trying to make a portfolio website (architectural design + concept art). Flash / programing are not my focus and this is my first go at learning the software. Due to the nature of the content and my (lack) of ability in AS3, I want the the coding to be really simple and still let the site look good. The way the site is currently structured:
1) Basic menu buttons that navigate to sections of the site (brings up a new page).
2) Example, clicking on <Graphics> takes you to a new page and a sub-menu animates in (simple motion tween for the buttons to cascade down). This animation is a movie clip placed on the main timeline.
3) On the screen is also a slideshow for all the images within <Graphics>. Instead of multiple small slideshows, I combined them all into one, so as to avoid complications with add / remove from stage. There are prev / next buttons that keep images within their sub section (ie 1->2->3->1). The sub-menu buttons are suppose to link to the start of each sub section, much like chapters on a DVD. (The slideshow is a movieclip sub-nested in the menu movieclip).
Main menu buttons work.
Sub-menu animation works.
Slideshow works.
Can't get the sub-menu buttons to access the slideshow chapters.
I have created and solved about half a dozen errors, and each time I fix something, it just causes another point to break. I've gone around in circles for days, and not sure which was is up anymore. So, while the slideshow works independently of the rest of the content, and I think I have the parent referencing correct, the problem I am currently facing is thus:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at 03graphics_fla::MainTimeline/frame1()
I've browsed some other threads, and I think I know what the problem is. Since the sub-menu is animated, the buttons do not appear on frame 1 of the nested timeline, while the actionscript is on frame 1 of the main timeline - thus the code doesn't exist yet when I click the button.
Is this indeed the problem? If so, how do I go about fixing it?
Additionally, does the structure makes sense on how my site is organized? Is there an easier / cleaner way to code it?
(This thing is completely ghetto-rigged, I just need it to function - it's like my own little Millenium Falcon...)
Cheers,
Andy

Hi again,
Thank you for helping. I really appreciate it! Would it be easier to say, if resumescrollMC exists, then execute these functions? I was not able to figure out the null statement from your post. Here is what I am trying (though I am not sure it is possible). I declared the var resumescrollMC, and then I tried to put pretty much the entire code into an if (resumescrollMC == true) since this code only needs to be completed when resumescrollMC is on the stage. It is not working the way I have tried, but I am assuming I am setting up the code incorrectly. Or, an if statement is not supposed to be issued to an object:
//Import TweenMax and the plugin for the blur filter
import gs.TweenMax2;
import gs.plugins.BlurFilterPlugin2;
//Save the content's and mask's height.
//Assign your own content height here!!
var RESUMECONTENT_HEIGHT:Number = 1500;
var RESUME_HEIGHT:Number = 450;
var resumescrollMC:MovieClip;
if (resumescrollMC == true) {
//We want to know what was the previous y coordinate of the content (for the animation)

How to access the Custom Data type variable given in Expression edit control To and From LabVIEW

Hello, I would like to know how to access the custom data type variable given in the Espression Edit Control from LabVIEW and vice-versa
Say, the FileGlobals.Reference_Handle (Custom Data Type Variable) contains the
VISA I/O session (Which in turn contains VISA_DeviceName: String, Session: Number),
Channel1: Number and
Channel2: Number
I am expecting the user to give FileGlobals.Reference_Handle as the input at the ExpressionEdit Control in the edit screen of the VI Call.
I would like to know how to get the values of this custom data type to LabVIEW?
Say, if I have the Cluster in LabVIEW like VISA I/O session (Deive Name and Session Number), Channel1 and Channel2
how do i need to set this cluster to the Custom Data type variable in TestStand?
Thanks and Regards
Prakash

Hi,
TestStand to LabVIEW: i didnt understand what you r trying to achieve. But if you are using references, Use Property nodes and Invoke nodes to achieve what you want in LabVIEW.
LabVIEW to TestStand: check the image below: You need to click the button next to 'container'. I have used a cluster output in the VI.
Hope this helps
