Hi,
getting back to the original question
I have question about for how many APIs I must familiar with if i want to become a Jdevloper ADF expert?+
I list down what i know:
+1. Java Standard API+
+2. Java Server Faces API+
+3. Java Servelet API+
+4. ADF API+
+5. any others? .....+
is my understanding correct?
Do you become an expert by knowing about these APIs and reading up on them ?
No, because APIs are just the vocabulary of a language or technology. For example: English is not my native language and I didn't even try to learn all of the vocabulary that I could learn. Instead I learned the vocabulary that I needed for the job and the related small talk therein. So I had my needs driving my learning. Same for ADF! If you want to become an ADF expert, start small and grow big. There are tutorial for you to start with and identifying the areas that you don't understand and that you need to read up on.
http://www.oracle.com/technetwork/developer-tools/jdev/overview/index-100269.html
There are a set of APIs in ADF that application developers usually work with
1. FacesContext
2. AdfFacesContext
3. ADFContext
4. BindingContext
5. ControllerContext
6. BindingContainer
7. JUCtrlHierBinding
8. AttributeBinding
9. JUCtrlListBinding
10. OperationBinding
However, these classes you wont need from start on. I just listed them to show the 20% that server you 80% of the time.
Beside of this there are some frameworks to learn about
JavaServer Faces
ADF Faces
ADF Business Components
ADF Binding
Rome wasn't built in a day and so does building up ADF expertise take its time. Do little baby steps - one at a time - and you find yourself becoming an expert soon. Follow tutorials for a start

How many computers can i use with creative cloud?

how many computers can i use with creative cloud?

Two.
From the Creative Cloud FAQ here http://www.adobe.com/products/creativecloud/faq.html under the section Purchasing and getting started:
On how many computers can I install the software I download from Creative Cloud?
You can install the desktop applications available in Creative Cloud on your primary computer and one backup computer, as long as they are not running at the same time. You will have access to both the Mac OS and Windows versions, so if you have a Mac at home and a PC at work, for instance, you can install your applications on both. See the product license agreements page for more information.

How many PCs can I use with one Creative Cloud subscription?

How many PCs can I use with one Creative Cloud subscription? For example I currently use Lightroom on a home PC with 2 large screens, but use a laptop or iPad when travelling. Does one monthly subscription cover all 3 or do I need 3 separate subscriptions ?

You are welcome!
P.S. when using the adobe forums, please mark helpful/correct responses of Staff or helper, if there are any.

Hi darylm32102489,
Which account are you referring to? I see that you have an Acrobat subscription--is that what you're asking about? Or are you referring to your Acrobat.com online storage account?
If you're referring to an Acrobat subscription, please see this FAQ for information regarding licensing: https://helpx.adobe.com/x-productkb/policy-pricing/acrobat-pro-xi-subscription-faqs.html#i d_83547
Please let us know if you have additional questions.

How many computers can I autorize with a single Adobe account?

As a librarian, I work in many schools. We slowly start to buy eBook for students with difficulties in learning. Often, books are protected by DRM: we have to use the same account to open the books that the one we use to buy it.
For now, only one person will be allowed to buy eBooks (me), so we will only have one account... but each student have his own computer, so I will have to autorize each computer with the same account.
1. Can I do that?
2. If yes, how many computers can I autorize with a single Adobe account?
3. If no, what else can I do?
Thank you very much,
Nancy Lusignan
Librarian
Commission scolaire des Hautes-Rivières, Québec

(1)You can do that with (2) up to six devices total including your computer.
(3) The only other thing is to try to contact Adobe to see what arrangements they can make.
Alternatively, contact Overdrive, who are the service most libraries use for lending ADE DRM books,
which is effecitvely what you want to do.
I am afraid I can't give any idea of the best contact points for those oarganizations.
Maybe some other public librarian will be able to point you in the right direction.

How many device can one sync with iPhone? I own a Mac Pro and an iMac desktop. Can I sync with both machines?

How Many devices can I sync with my iPhone? I own a Mac PRO and an iMAC. Depends on where I am, I will plug my iPhone to either of the machines. I haven't sync with either machine yet.

Dah•veed wrote:
Please explain how one would accomplish that feat.
There's not much to explain. When a device is connected, you see the row of different categories across the top: Summary, Info, Apps, Tones, Music, Movies, TV Shows, Podcasts, Books, and Photos. For example, it is perfectly safe to sync one iOS device to the Music category on Computer A and no other computer, and the same device to Photos on Computer B and no other computer.
You might be confusing what I'm saying with one iOS device enabling sync to the Music library on multiple computers. That is a huge no-no and will result in the disaster being suggested. But I am not talking about that, I'm talking about the opposite arrangement. What I am describing preserves category exclusivity. It turns out that exclusivity at the category level, not the computer level, is what really matters.
As long as a device is synced to a given category on only one computer, it doesn't matter which computer it is or whether that computer is different than the ones synced to on other categories. The instant a given category is enabled for syncing on more than on computer, that is where the trouble starts.

Trying to do so is asking for trouble. Don't do it. Move the content you need to one machine and sync only with that machine. If you don't, you'll be back here asking how to fix the mess and recover all the stuff you lost...
I will agree that it is something you should only do mindfully. But if you do make sure each category is syncing to only one device, there will be no data loss and no mess.

XmlDataProvider .... is gone completely in my Xaml file. Why? How many different ways to deal with xml data source through WPF

I followed a procedure described in a book.
1. insert "Inventory.xml" file to a project "WpfXmlDataBinding" .
2. add the XML data source through the data panel of "blend for 2013", named it "InventoryXmlDataStore" and store it in the current document.
3. dragged and droppped the nodes from the Data panel onto the artboard.
Then I checked my Xaml file against the one provided by the book
Xaml file by the book:
<Window.Resources>
<XmlDataProvider x:Key="InventoryDataSource"
Source="\Inventory.xml"
d:IsDataSource="True"/>

<DataTemplate x:Key="ProductTemplate">
<StackPanel>
<TextBlock Text="{Binding XPath=@ProductID}"/>
<TextBlock Text="{Binding XPath=Cost}"/>
<TextBlock Text="{Binding XPath=Description}"/>
<CheckBox IsChecked="{Binding XPath=HotItem}"/>
<TextBlock Text="{Binding XPath=Name}"/>
</StackPanel>
</DataTemplate>
</Window.Resources>
<Grid>
<ListBox HorizontalAlignment="Left"
ItemTemplate="{DynamicResource ProductTemplate}"
ItemsSource="{Binding XPath=/Inventory/Product}"
Margin="89,65,0,77" Width="200"/>
</Grid>
my Xaml file:
<Window x:Class="WpfXmlDataBinding.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="922" Width="874">
<Window.Resources>
<DataTemplate x:Key="ProductTemplate">
<StackPanel>
<TextBlock Text="{Binding XPath=@ProductID}"/>
<TextBlock Text="{Binding XPath=Cost}"/>
<TextBlock Text="{Binding XPath=Description}"/>
<CheckBox IsChecked="{Binding XPath=HotItem}"/>
<TextBlock Text="{Binding XPath=Name}"/>
</StackPanel>
</DataTemplate>
</Window.Resources>
<Grid DataContext="{Binding Source={StaticResource InventoryXmlDataStore}}">
<ListBox HorizontalAlignment="Left" Height="370"
ItemTemplate="{DynamicResource ProductTemplate}"
ItemsSource="{Binding XPath=/Inventory/Product}"
Margin="65,55,0,0" VerticalAlignment="Top" Width="270"/>
</Grid>
</Window>
All looks quite the same except the <XmlDataProvider ....> part under <Window.Resources>, which is gone completely in my Xaml file.
1, Why?
2, How many different ways to deal with xml data source through WPF?
Thanks, guys.
(ps My "WpfXmlDataBinding" runs without problem through.)

Never do yourself down Richard.
Leave that to other people.
It's quite common for smart developers to think they're not as good as they are.
I coach a fair bit and it's a surprisingly common feeling.
And to repeat.
Never use anything ends .. provider. They're for trivial demo apps. Transform xml into objects and use them. Write it back as xml. Preferably, use a database.
You want to read a little mvvm theory first.

Whatever you do, don't read Josh Smiths explanation. I used to recommend it but it confuses the heck out newbies. Leave that until later.
Laurent Bugnion did a great presentation at mix10. Unfortunately that doesn't seem to be working on the MS site, but I have a copy. Download and watch:

I'm writing an article at the moment which is aimed at beginners.
http://social.technet.microsoft.com/wiki/contents/articles/30564.wpf-uneventful-mvvm.aspx
The sample is just a collection of techniques really.
I have a sample which involves no real data but is intended to illustrate some aspects of how viewmodels "do stuff" and how you use datatemplates to generate UI.
I can't remember if I recommended it previously to you:
https://gallery.technet.microsoft.com/WPF-Dialler-simulator-d782db17
And I have working samples which are aimed at illustrating line of business architecture. This is an incomplete step by step series but I think more than enough to chew on once you've done the previous stuff.
http://social.technet.microsoft.com/wiki/contents/articles/28209.wpf-entity-framework-mvvm-walk-through-1.aspx
The write up for step2 is work in progress.

How many installs do I get with a Creative Suite License

How many installs do I get with a Creative Suite License and if more than one can I put a copy on MAC and Windows?

Hi Isendusersup,
You can install software on up to two computers. These two computers can be Windows, Mac OS, depends on the Platform for which you bought the product (Creative Suites License ). For Creative Cloud subscription, it can be any two platforms.
If you install on a third computer, it will request you to de-activate on the other two computers. You can then reactivate one of the previous two computers, and use Creative Suite license or Creative Cloud apps on it.
For Creative Suite - To deactivate from preinstalled machine, Open any Adobe CS application > Help Menu > Deactivate.
For Creative Cloud - To deactivate from preinstalled machine, Open any Adobe CC application > Help Menu > Sign out.
Let us know if you need more assistance.
Thanks!
Eshant
