Your best bet is to ask in the forum that's under the article. The author understands how his code is supposed to work, and we don't.

I did and like other people, he is not responding. Oh well, I guess I will find something else to use...

Sorry, I've never used it. I would suggest running his sample and looking for ways your code is different to his sample.

Back in the late 90's Java was main stream and XML was becoming popular, a Sun researcher from China postulated that a Swing or AWT UI could be represented by dumping the widget cache to an XML file and then reconstituted using XML parser and Java Reflections.
I was unable to find the original white paper...
I used this researcher's design pattern on a contract once to create a XML version for winforms.

1 - this is not a question
2 - C# is obviously based on Java, so what else is new ?
3 - Sun is so awesome that they come up with these ideas, but can't make money off them. How many quarters have Sun made a profit in, in recent years ?
4 - anyone who is trying to create new technology would be stupid to set out NOT to learn from what people have done in the past.
Forgot to add - XAML is the worst thing about WPF. Too verbose, for one. It's often better to do stuff in code.

Hmm, Kinda of thought this was an an implied question. Esp. if you can prove other wise.
Christian Graus wrote: 2 - C# is obviously based on Java, so what else is new ?
Yeah, kinda of, but I think the direct relationship faded around 3.0. 3.5 and 4.0 bring new ideas to the table, and Sun has been playing catch up since Generics.

Gotta love those guys, but it makes you wonder how many quarters Stanford's research grants increased...

Hmm, I wouldn't say stupid. Pig headed maybe.

Well Okay, good point. What about designers? Don't they get to play? Try using Model Viewer Presenter with WPF. Where XAML = Viewer, xaml.cs = Presenter, You'r logic = Model. That might work better.

True - but that is kind of my point. Innovation and the replication of good ideas from the past, are not mutually exclusive.

Hell, yes. I spent hours reading through Beagle Brothers code and learning from it, I had their posters up on the wall around my computer. I loved those guys.

Me to! My first programing book was Beagle Basic and Pro Dos. The IIe didn't have a clock so my fisrt attempt at programming was a huge sub to count the ticks and update the clock on my BBS with out have to buy a $240 add in board just to tell what time it was. Little did I know I was reinventing multi tasking.

With their upcoming "M" meta-language, I wonder how long it will be before some one make a new declarative curly brace based language.
One which act like XAML but feels like C#!

And here I was, thinking some idiot at Microsoft just pulled it outa' their ass. In any case, I like my version better because it's a better fit.

Make sure you don't get caught out by attempting to install the consumer version when you already have Silverlight 2 Tools installed. I ran into that. You need to install the v3 Tools and all will be OK.

I am glad that you pointed that out since I would have been googling for it to solve the issue. I am sure that others have had that happen too. Sad thing is that I have updated my Mac to Silverlight3 but not my PC yet

I thought that if I didn't assign a key name to a style, that the style would be applied to all instances of the specified target type.
I put such a style into a resource dictionary that is merged in the app.xaml file, but *none* of the target controls are using the style.
If I put the style into a specific control/window xaml file, or if I give the style a key name and use it that way, it works as expected.
What am I doing wrong?
EDIT ---------------
Well, I need to move on, so I found an almost reasonably low-impact work-around. I left the style in the dictionary file, but I gave it a key name. I then created a derived style in the resources section of each applicable window/user control like so:
<Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource TextBoxStyleBase}" />
This has the effect of applying to all of the textbox controls in the containing window/user control without me having to assign the style to each one.
I think what I've found is a bug in WPF, but I'm sure that Microsoft will claim that it's working as designed.

I have a resource dictionary Dictionary1.xaml that looks like this:
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
>
<Style TargetType="Button" >
<Setter Property="Background" Value="#FFFF0000" />
</Style>
</ResourceDictionary>
I merge it into an app's resources in App.xaml like this:
<Application x:Class="WPFTester.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="Window1.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Dictionary1.xaml" />
<!-- Example importing resource dictionary from another assembly -->
<!--<ResourceDictionary Source="pack://application:,,,/WpfCustomControlLibrary;component/Dictionary1.xaml" />-->
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
All the buttons in the app, unless otherwise styled, have red backgrounds.
What did you do different? Are there other styles earlier in the search order that are
overriding your app-level styles?

You can use your user controls just like any other UI element.
What part are you having trouble with?
I'm not sure why your topic mentions converting XAML to PNG.....that certainly
has nothing to do with the example link you provided.

I am thankful to your answer.
Actually, I want to create silverligt application same as mentioned in the above link which I had given. In that link When I see the view source then I find that they have used .png files.
Please advice me how to create/steps to silverligt application same as which I had mentioned.

There are two steps to take any part of the page and convert to a PNG.
First, get it into a bitmap. That's simple enough. Let's say your page looks like this:
<grid x:Name="mainGrid">
<component1/>
<component2>
<nestedcomponent3/>
</component2>
</grid>
To get this to a bitmap, just do an empty transform on the grid;
WriteableBitmap bitmap = new WriteableBitmap(mainGrid, new TranslateTransform());
Now you've got your bitmap (you can do an Image.source = bitmap for example and show it)
Next, getting it to a PNG - that's a little more complicated, but also has been addressed with some libraries, like this one:

Best of success!
