How do I address the scrollbar's updateDisplayList properties if I do not instatiate the scrollBar component?

Is there an easier route?
My issue is that I am not attaching the scrollbar via
<mx:HScrollBar or mx:VScrollBar, rather it is being
automatically attached to a container. Therefore my only means of
addressing this particular scrollbar seems to be from within the
condainer's script, and the container's properties do not make
provision for it's child scrollBar's height/width.
Is it a matter of re-writing the default scroll component?
For example, I've skinned a scrollBar using the examples at
Narciso Jaramillo's
http://www.adobe.com/devnet/flex/articles/flex_skins.html
(using Flash) but this article does not explain how to
override the default scaling.
Next I've applied the skins to the Adobe example,
http://examples.adobe.com/flex2/inproduct/sdk/photoviewer/srcview/index.html
within the ThumbnailView.mxml file there is a Vbox containing
a HorizonalList container with the id of photoList , that when
loaded, adds a HorizontalScrollBar, like this..
<mx:HorizontalList id="photoList"
dataProvider="{gallery.photos}"
width="98%" height="135" selectedIndex="0"
itemRenderer="Thumbnail"
styleName="thumbnailList" />
I understand that the scope of this matter may be small in
comparison to other issues but as a designer these otherwise simple
tasks are terribly frustrating and time consuming.
I would appreciate any insight.
Thank You,
Key.

How lync 2013 addressed the new public certification standards

Dear All,
My AD domain name is "domain.local" .
I’m planning to implement lync 2013 and I need to know how lync 2013 addressed the new certificates standard regarding the non-registered domain name like my domain “Domain.local” ?
So can I generate the certificate for lync services without “.local” domain or my certificate should include my lync servers internal names ?
Or should I consider changing my domain name to domain.com cuz lync certificate should have internal domain names?
BR, Mohamed Wahab "Egypt Cyber Center"

Hi mohamed.wahab,
For non-domain joined PCs, you need to install the internal root certificate on them.
For mobile phone and tablets, you do not have to install the internal root certificate, because they always connect to the Lync server through Reverse Proxy, regardless of where the origination
point is—internal or external.

Eric

How to find out the Target Component name and Target view name

Hi All Expert,
                  I want to know ,how to find out the target component and target view in WEB UI,when i click on a field which shows as a hyper link in WEB UI .At GUI level ,i know the how it will work.Any way to find out the component name and view name which is show the details of that field at GUI level .IF you go to transaction CRMD_ORDER then open the service contract id .then goto the item level value .there is 1 service data tab is available at item level.there is two button is available.first one is available time and second one is response time .if i click on any button then one popup is open which is shows the details of that button.I dont know how to find out the component name and view name from GUI level.
Thanks in Advance....
Vishwas Sahu

Hi Vishwa,
             The control would be something like this for navigation in Get_p_xxx method u mention as link and u mention a event name which gets triggered on the click of this hyperlink. So your GET_P_XXX method would have the following code:
CASE iv_property.
    WHEN if_bsp_wd_model_setter_getter=>fp_fieldtype.
      rv_value = cl_bsp_dlc_view_descriptor=>field_type_event_link.
    WHEN if_bsp_wd_model_setter_getter=>fp_onclick.
      rv_value = 'EXAMPLE'.
Now you have to create a method as EH_ONEXAMPLE at your IMPL class and within which you would give an outbound plug method. Within the outbound plug the target data would be filled in the collection and window outbound plug would be triggered.
This is a huge topic and i have just mentioned you basic things.

How can I know the right component for a transaction?

Hi, I have a question
When creating a new message in Solution Manager, notif_create, how can I know the right component given the transaction code or program name?
Thanks in advance
Edited by: María Valdés on Aug 19, 2008 6:25 PM

Hello Maria,
Well, in the Support Message window, place the cursor in Component box and press F4. This will brings up another window which contains the components list to which you are authorized. From that list you can choose about which component you want to create that particular support message.
For example, if you are from Quality department, the following can be visible when you press F4.
QM - Quality Management
-- QM-ADB Adobe Forms
-- QM-ADB-PRN Print Forms
For the Print Forms, the component will be QM-ADB-PRN
I hope it helps.
Cheers,

Referenced and Referencing Component Usages Must Address the Same Component

Hi,
I have a main component MC and it has two used componenents - IBLC and IVAC (interfaces for model and visual compoenents).
I get the actual model component name from a table and I instantiate it as follows:
instantiate model component
DATA: l_ref_model_usage TYPE REF TO if_wd_component_usage,
l_my_initial_usage type ref to IF_WD_COMPONENT_USAGE.
L_MY_INITIAL_USAGE = wd_this->wd_cpuse_iblc( ).
l_ref_model_usage = L_MY_INITIAL_USAGE->CREATE_COMP_USAGE_OF_SAME_TYPE(
NAME = Item_Modelcomp ).
Components VC1 and VC2 etc implement IVAC.
Since I want to use the same instance of Item_Modelcomp in VC1 and VC2, I use the set_model(and from that I call method enter_referencing_mode) method as follows in MC.
l_ref_interfacecontroller->set_model( model_usage = l_ref_model_usage ).
Now in set_model method in VC1, I am using Item_Modelcomp as used component and not IBLC because I want to use the Item_Modelcomp context, but it expects IBLC as the used component(even though Item_Modelcomp implements IBLC) and hence gives the error "Referenced and Referencing Component Usages Must Address the Same Component".
Any solution for this issue?
Thanks and Regards,
Srini.

Hi Srinivasa,
>I thought model compoenents are the ideal way to share
>context across different visual components.
Yeah, we though the same in the beginning. Later on we learned that:
- it's not worth having the overhead of another WD component in most cases since you need to call the business logic nonetheless
- declaring nodes as public is like having public attributes at a class - which can be really bad thing
- there are lots of side effects regarding one component affecting the other one indirectly by having both mapped to the same model component
In general, using model components should be avoided. There might be rare cases, where it makes sense to use them, but mostly it's not worth the effort.

Thomas

How to get only the dc component of a dc signal with noise?

I need to read a temperature value (a dc value). However signal has some noise in it, and i need to get it out. How can i make it? Using a low pass filter? Which one.? Is there any DC pass filter?

First, depending on the sensor you are using and how you are making the measurement, make sure you use the appropriate VI from the palette:
Data Acquisition -> Signal Conditioning
Sure you can use most of the filters located in:
Signal Processing -> Filters
Create a constant from the "filter type" input and select "Lowpass".
There is also an AC & DC estimator vi, located in:
Signal Processing -> Measurement
Always remember to check the shielding of your system.
Finally, check the following at NI, which have good information on how to get rid of noise:
DC voltage

How can I get the DC component out of a signal in Labview

I was trying to get the DC component of a signal using lowpass filters provided by Labview(professional version 8.2). I used the FIR windowed filter but I couldn't get what I expected. The sample rate is 20* the maxium signal frequency. I simulated a function like y= 10(volt)+Sin(2*pi*f*t+phase). If I set the low cutoff to be less than the frequency f, shouldn't I get 10 volt as the outputs? See the attachment for vi. Thanks!

Hi,
You can use the filters located in Signal Processing -> Filters, then create a constant from the "filter type" input and select "Lowpass". There is also an AC & DC estimator vi, located in: Signal Processing -> Measurement.
You may also use something like "running mean" filter. To do it you need to calculate the mean value in some range around every point. It will decrease the value of the noise and will give you the dc value (or slow changing part) of your signal. Finally you can use median filter.

How do you change the Tree Component Icons?

Hi,
I have been trying to get to grips with the tree component. I
want to
customise it so that I can have a different icon for each
different link.
E.g. a QT logo for a video etc. If no valuse is found for the
'icon'
attribute it will just display the default.
Within my XML file I have created a new attribute for each
link called
'icon' and has a value of 'movie.gif' or something similar.
In my flash file, I have created the following code:
theTree.iconFunction = function (node:XMLNode) {
var iconNode:String = item.attributes.icon;
if (iconNode != undefined) {
return iconNode;
However, it does not seem to work. My knowledge of
ActionScript is pretty
poor so I assume I have made a mistake in there somewhere.
Can anyone help
me with this?
Thanks!

Check out the Component Reference... you change the icon for
a single node, as far as I know there's no automated process beyond
that. So assuming your tree component instance is named "theTree"
you might do this to change the icon of the first node:
theTree.dataProvider = yourXML; // make sure you don't try to
change the icon before you load data into the tree
var theNode = theTree.getTreeNodeAt(0); // the first node in
your tree
theTree.setIcon(theNode,'myIcon'); // set the icon
Where "myIcon" is a MovieClip you have in your library that
you have set the "linkage identifier" as "myIcon".
That iconFunction doesn't make a whole lot of sense to me,
because first of all I don't know why it would be attached to
theTree, and second it's referring to "item" which is not defined,
and third its taking the parameter "node" and not doing anything
with it. But perhaps there is some cool way to make a single
function which handles icons for your entire tree automatically,
that would certainly be nice.
However, like I said, as far as I know that function will do
nothing without calling tree.setIcon() in some way. I just made a
function which might do what you want -- it recursively loops
through an entire tree and sets it's icon based on the XML
attribute "icon":
function setAllIcons(branch){
for(var i in branch.childNodes){
var node = branch.getTreeNodeAt(i);
theTree.setIcon(node,node.attributes['icon']);
if(node.hasChildNodes){
setAllIcons(node);
So basically, you run setAllIcons(theTree.dataProvider) after
you have loaded and applied the XML.

How do I know if I have a wifi problem with my new iPad 3 (it seems very slow) and how does one address the problem with apple if there is one?

I just read about the possible issue that some folks are having with their new iPad wifi (my seemed to be running very slowly but I thought that perhaps it was just me overreacting). How do I know if I have a definite problem, and what is my recourse? Do I need to take it to an Apple store for testing? I have apple care which I assume addresses stuff like this. Thoughts? Thx so much.

Your iPad is covered by the normal warranty for one year. If you have AppleCare that extends the coverage. If you feel there is a problem with your wifi reception visit an Apple store with your iPad for a consultation. Be sure to make an appointment before you go.

How do I set the value of a dynamic row text field

I have a repeated row form which contains a button and multiple text fields. There is a text field (Input Data Field) further up with some information I want to place in the table and multiple buttons that I want to read the value of and set to the table. I apologize there are multiple questions I have and I am using pseudocode to describe it.
Top form looks like
InputField
| ButtonX1 | ButtonY1 | DescriptionX1 (read only Text Field)
| ButtonXn | ButtonY1 | DescriptionXn
OutputRow looks like
| ButtonOutput | OutputField1 | OutputField2 | OutputField3 |
So I would like it to do
ButtonX1.click
OutputTable.OutputRow.addInstance(true) //this works - everything else I have questions on
OutputTable.OutputRow.OutputField1.rawValue = DescriptionX1.rawValue
Question 1
How do I address the location in each table to set a value
Question 2
How do I get the value of the description field in the same table and row as the button
I would like to say something to the effect of OutputTable.OutputRow[??].OutputField1.rawValue = this.parent.DescriptionX
OutputTable.OutputRow.OutputField2 = InputField.rawValue
Same question as above - how do I specify a dynamic row - is this the proper syntax for getting the value from the input field?
OutputTable.OutputRow.OutputField3 = this.ButtonLabel
Question 3
How can I get the value of the button's label to set in the field
There should be very many of these buttons and buttons will be added - I would prefer to set the value based on the button's label to make the value easier - not requiring changing the code
Question 4 - unrelated to those above.
Is it possible to build the first table
| ButtonX | ButtonY | Description |
from an XML File. I have seen examples of how to build if it is just data, but can the XML be pushed into a form with code to do the above actions?

Each object in a form must have a unique name. I doing so it is not neccessarily the name but the path or SomExpression associated with that object that must be unique. In your case you have a Table.Row.object configuration. The Row is the part that is repeating so to give each object a unique name an instance number is placed on the repeating part. So objects in the 1st row woudl be Table.Row[0].object...objects in the second row woudl be Table.Row[1].object etc .....You can see this by adding a debug instruction on the Enter event of the description field. Put the code app.alert(this.somExpression) and when you enter the field you will see what the somExpression is. Do this for a few rows and you will see the pattern (don't forget to remove the debug code from the enter event). Now you know what you have to use to address the fields. If no instance is given it is assumed to be 0 ..that is why only the 1st row is being affected.
So now to answer your questions:
Question1: The square bracket notation is an issue for javascript (this is the notation for an array) so we have to use a different means of addressing the field to include the instance number. So to address the Description in the 3rd row we woudl use:
xfa.resolveNode("Table.Row[2].Description").rawValue = "This is my new description";
Note that the instance number is 2 for the 3rd row because the instance numbers are 0 based.
Question2. The resolveNode notation allows you to pass a string so you can also concatinate expressions to make the string. If you are writing code on a button in the same row you can get the instance that you are on by using the expression this.parent.index. The "this" portion refers to the current object (the button) and the parent.index gets you th eindex of the Buttons parent. If the button is embedded deeper in a hierarchy then you can continue to add parent indicators until you get back to the node that you want. So rewriting your expression from Q1 it woudl be:
xfa.resolveNode("Table.Row[" + this.parent.index + "].Description").rawValue = "This is my new description";
Question3: The buttons caption can be retrieved by using ButtonName.caption.value.text.value
Question4: When you say build from an XML file. What are you expecting to come from the XML file? The caption that goes on the button? Typically the XML file carries data (not to say that it cannot carry other things). Just need a bit of clarification on this one first.
Hope that helps

Assign the cost component Structure to Plant/Co Code

hi
can u tell how can i assign the COST COMPONENT STRUCTURE TO THE PLANT AND THE CO CODE...
REGARDS

Hi,
This is part of Product costing configuration and done with T-code OKTZ. Here, there is a separate diaglog for Assignment of Org units --> cost component structure.
Here, for a particular co. code and all the plants under this Co. code or for only a certain plants and further to a specific costing variant the assignment is done to the cost component structure effective from certain date.
Good Luck!!!
