This is very simple question. Parent-Child Relationshiop

Hi~ All.
I think this is not too difficult. But I'm newbie to Flex
I don't understand relationship of Parent-Child, and what's different .addElement, .addChild.
I made some code.
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
      xmlns:s="library://ns.adobe.com/flex/spark"
      xmlns:mx="library://ns.adobe.com/flex/mx"
      width="481" height="442" minWidth="955" minHeight="600" creationComplete="initApp()">
<fx:Script>
<![CDATA[
   private var _cam:Camera;
   private var _vid:Video;
   private function initApp():void{
    _cam = Camera.getCamera();
    _vid = new Video();
    _vid.attachCamera(_cam);
   private function createMyVideo():void{
    view.addChild(_vid);
]]>
</fx:Script>
<fx:Declarations>

</fx:Declarations>
<s:Button x="36" y="71" label="Create My Video" click="createMyVideo()"/>
<s:VGroup x="192" y="71" width="200" height="200" id="view">
</s:VGroup>
</s:Application>
When I click the button, I wanna show my live video.
But I got a error message.
Error: addChild() is not available in this class. Instead, use addElement() or modify the skin, if you have one.
What's my mistake?
Thanks in advance.
Kevin.
ps. Sorry for my English.

This post has a good description of elements vs. children: http://www.billdwhite.com/wordpress/?p=296

This is a very simple question,but I don't know.Please me.Thank you!

I am a Chinese student in a university.I have a very simple question to ask.
I have writed a EJB module,and I have deployed to Weblogic8.1 successfully.
1.Now I want to write a client program.Is it necessary that the client program is packaged in the EJB package.For example ,the EJB package is Beans,is "package Beans " or "import Beans.*" necessary in my client program.
2.If I only know the EJB interfaces,that means the EJB module is writed by other programer.I want to know how I can write the client program.How can I call EJB module's method writed by other programer.Could you give me a simple example?
Thank you very much.

Very simple question, how do you configure windows 8.1 to use a SF card as the default install location for software applications?

Very simple question, how do you configure windows 8.1 to use a SD card / external drive as the default install location for software applications? Primarily interested in apps installed from the windows store. This should be available in the settings
charm within the windows store. This must have been overlooked in the development of windows 8.1 or is a bug.

The registry method does not work with 8.1. I found this out the hard way. Doing it on 8.1 will leave you reinstalling the OS if you didn't do a SRP beforehand.

A very very very simple question

Hi guys,
I have a very simple question and standard but I cant find anywhere...
I have two dateTime variables, i need to calculate difference between this dates in days, thats it.
I tried all functions and tried without success a Java Embed task but I couldnt retrieve this objects as java.util.Date so I couldnt calculate exactly the difference in days like this pure java code:
(dataVencimento.getTime() - dataReferencia.getTime()) / 86400000L)
can you help me this?

Hi Jose
Just see if these alternate approaches works. I know there may be lot like this and you may be lucky to find out simple out of box solution itself. If you want to solve this issue and move ahead, gives these approaches a shot.
1. Create a very simple standalone WebService that takes 2 input date elements (can be of Date type or String type. If string type, convert to date in your java code). Create a simple operation like getDaysBetween(firstDate, secondDate). In the generated webservice impl class, use the java code apis (refer earlier link for usage), and get the difference. Return this value. NOW, invoke this WebService in your BPEL Process, and pass your 2 inputs (if the bpel payload elemetns are date object or string objects of date), and get output, and then use this output in your continuing bpel process.
2. This approach, I did a long back. When we insert any expression using XPath, in that editor window on bottom right side, we see many categories and for each category we see list of functions we can use, like for String, we can use concat etc. I vaguely remember reading somewhere, that we can add our own custom functions also in this section. So explore this direction and see if you can add your own function and then use that fucntion with your 2 input dates.
I have not given solution to your problem, but may be these directions can help you move ahead. Or something along these lines.

A very simple question..Very Urgent

HI,
I have a very simple question.I am able to set up the client authentication as well as server authentication. Now do i need to authenticate (both server as well as client auth.) for every request i send to the server on https...i think it should be like that it should authenticate only for the first time and for the next upcoming requests in same session should not require any server or client authentication.. i think as it happens in browsers..
what is the fact actually??..can somebody put some light...right now in my case it is authenticating for every requests..
This is what i have done..
/****constructor part********/
// and tm are arrays of keymanagers and trustmanagers for client keystore and truststore
sslContext.init(km, tm, null);
HttpsURLConnection.setDefaultSSLSocketFactory(ssf);
HttpsURLConnection.setDefaultHostnameVerifier(new MYHostNameVerifier());
/****Method to send the request and response*********/
urlConn = (HttpsURLConnection)url.openConnection();
urlConn.setDoInput(true);
urlConn.setDoOutput(true);
OutputStream os = urlConn.getOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(os);
oos.writeObject(someobject);
oos.flush();
InputStream is1 = urlConn.getInputStream();
ObjectInputStream ois = new ObjectInputStream(is1);
SomeObject retObj = null;
retObj = (SomeObject)ois.readObject();
ois.close();
System.out.println("Get String>>>>> "+retObj.getString());
I am creating the object of this class..and calling the method again and again for sending requests and response..so i think handshake everytime i call the method...what i want is that handshake should happen for the first time and for the next requests no handshake or certificates should be checked or processed..
is it possible ..how..what i need to do for that..
please help me in this..

HT4753 I have a very simple question: how do I view where Lion has autosaved my current version to (without the convoluted route of using finder)? In days gone by i'd simply use the save as function to see where it was being saved.

I have a very simple question: how do I view where Lion has autosaved my current version to (without the convoluted route of using finder)? In days gone by i'd simply use the save as function to see where it was being saved.

It's actually even easier than using Save As to see the full path to the currently open document. Just do a "Secondary click" on the document title in its window's title bar.
Like you, I relied upon Save As my whole life to check a file's location and considered it a must-have capability. Turns out it's even faster to use the single-click method to reveal the full path to the open document. It displays the entire path to the current document starting from the level of your Mac, and works for files stored on drives as well as iCloud.
If you're not sure how to do a secondary click, go into System Preferences, select Trackpad, Point & Click to find the current preference for secondary click on your Mac. If you happen to have a mouse with more than one button, it's probably the right button. As a trackpad user, I check the box to "Click or tap with two fingers," so a simple two finger tap on the title of an open document reveals its full path. This feature actually has been around for a very long time.
Note that this is not the same thing as the Autosave and Versions menu, which is exposed using a little drop down triangle to the right of the title. There is no visual clue for the presence of this feature - you just have to know it's there, probably because this feature goes all the way back to pre-OS X days.

How do I select a square brush for the brush tool in CS6? Sorry if this is a simple question, but nothing has ever been simple for me in Photoshop.

How do I select a square brush for the brush tool in CS6? Sorry if this is a simple question, but nothing has ever been simple for me in Photoshop.

I don't believe there is a square brush among the sets that ship with Photoshop, but there are plenty to download, and it is super easy to make one.
Just drag with the rectangular Marquee tool, fill with black on a new layer, and go Edit > Define brush preset

Not any more, no. There was a free bumper program back when the iPhone 4 originally came out. It has long since expired.

Very urgent- find parent-child relationship for wbs element

Hi,
There is a certain parent child heirachy in WBS elements.My requiremnet is to delete WBS element depending on certain field , say depending on some ""status"".If the status is active in some or any of the child then I am not suppose to delete its respective parent too. This parent-child relation can have say 5 levels.
For this I require a logic /program which shall maintain the parent reference for that particular child whih I want/ dont want to delete.
I am maintaining bottom- to -top approach.
That is I shall be checking for the status of the lowest level of WBS and then going to the highest.
Please Help!

Very simple question from a rookie

Hi,
I don't know how sequences work in OWB.
I have a very simple mapping:
1 (not empty) source table, 1 (empty) target table, 1 sequence.
Source and destination are connected.
The sequence.nextval is connected to the primary key. sequence.currval is not connected.
When I run the debug mode an error occurs: "Could not find data for all sources and target ...". The "Test Data" shows that OWB has not found data for the sequence.
Help!

I use 10gR2 and OWB 10.2
The tables and the sequence are deployed. They are in the database.
There's something strange about this:
Starting ("Start...") works.
The debugging does not work.
Problem nearly solved ...

I am currently doing a little exercise, but I ran into a problem. I have written a class that supports operations on rational number. The fields are two long variables, one each that stores the numerator and denominator.
I have made add, subtract, multiply, and divide methods...
1. what I need help in is: beingh able to store the rational number in reduced for, with the denominator always positive
2. constructing a toString method, equals method, and compareTo method.
3. it also says "make sure the toString method correctly handles the case in which the denominator is zero by throwing an exception.
I have been working on this for a long time now, an I am stuck at this point.
I know this will be very simple for you guys and gals, but I am a beginner. Please offer some input, advice, and/or some code to help me get past this problem.
Thanks so much,
Jason

ok, here is what I have so far
public class Rational {
     public long num, den;
     public Rational(long n,long d) {
          this.num = n;
          this.den = d;
     public static void main(String args[]) {
          Rational r = new Rational(1,2);
          Rational s = new Rational(3,4);
          Rational rmuls = r.multiply(s);
          Rational rdivs = r.divide(s);
          Rational radds = r.add(s);
          Rational rsubs = r.subtract(s);
          r.print();
          s.print();
          rmuls.print();
          rdivs.print();
          radds.print();
          rsubs.print();
     public void print(){
          System.out.println(this.num+ "/" +this.den);
     public Rational multiply(Rational t){
          long n;
          long d;
          n = this.num*t.num;
          d = this.den*t.den;
          Rational answer = new Rational(n,d);
          return answer;
     public Rational divide(Rational t){
          long n;
          long d;
          n = this.num*t.den;
          d = this.den*t.num;
          Rational answer = new Rational(n,d);
          return answer;
     public Rational add(Rational t){
          long n;
          long d;
          n = (t.den*this.num)+(t.num*this.den);
          d = t.den*this.den;
          Rational answer = new Rational(n,d);
          return answer;
     public Rational subtract(Rational t){
          long n;
          long d;
          n = (t.den*this.num)-(t.num*this.den);
          d = t.den*this.den;
          Rational answer = new Rational(n,d);
          return answer;
     //public int compareTo (Rational t)??????

Very simple question about webapp list layout.

Hi Everyone!
I am having a very simple issue. I have created a web app and it has a default list layout looks like:
<table><tbody><tr><td>{tag_counter}. {tag_name}</td></tr></tbody></table>
I have placed web app module (using {module_webapps,14273,a} ) in one of my page. In front-end it has show every thing fine except it shows table tag for each item:
<table>
    <tbody>
        <tr>
            <td>1. <a href="/lot/lot-101">Castlepoint Lot 101</a></td>
        </tr>
    </tbody>
</table>
<table>
    <tbody>
        <tr>
            <td>2. <a href="/lot/efg-lot">EFG Lot</a></td>
        </tr>
    </tbody>
</table>
<table>
    <tbody>
        <tr>
            <td>3. <a href="/lot/some-lot">Some Lot</a></td>
        </tr>
    </tbody>
</table>
<table>
    <tbody>
        <tr>
            <td>4. <a href="/lot/some-other-lot">Some Other Lot</a></td>
        </tr>
    </tbody>
</table>
When I delete table and tbody tags from list view, it stop showing table related tags instead it start showing it without any tag.
How to correct this issue? Please help!!!

Here is what you can do:
-edit the webapp list layout via FTP or via the "alpha" File Manager. The WYSIWYG editor will attempt to "correct" your HTML code. Enter something like this:
<tr>
<td>
{tag_counter}. {tag_name}
</td>
</tr>
-on the page you need the listing placed on enter this code:
<table>
<tbody>
{webappmodule here}
</tbody>
</table>
When the page renders you will get the desired result:
<table>
<tbody>
<tr><td>1</td><td>Item1</td></tr>
<tr><td>2</td><td>Item2</td></tr>
<tr><td>3</td><td>Item3</td></tr>
<tr><td>4</td><td>Item4</td></tr>
</tbody>
</table>

Editing photo title - very simple question

this seems so simple I am embarassed to ask - I want to change the title of a photo after I import. the help function says use the title box. but the title in the finder never changes so if I want to locate the photo for some other purpose out side of iphoto it is extremely difficult.
does that finder title never change? (if so seems to be poor functionality)
how do I change it other than thru the finder?

HI David,
Yes the title you give a photo within iPhoto stays within iPhoto.
Two Apple kbs for you to read
Don't tamper with files in the iPhoto library folder
About the iPhoto Library folder
To do what you want you have to name the photos before importing into iPhoto. Either download to the computer with your camera software or use Image Capture (found in your Applications folder) to download the photos.
Launch Image Capture (keep the little window open that says no camera is connected or IC will quit if you close the window)
Go to Image Captures preferences and choose what you want to happen when a camera is connected.
Next time a camera is connected, if you chose Image Capture to open, then IC will open and download the photos.
Rename your photos then add to library/import them into iPhoto.

This is very simple question. Parent-Child Relationshiop
