DNE Support – Deterministic Networks.

The current instance of WebContext is not available. You must instantiate a WebContext and add it to Application.ApplicationLifetimeObjects within the default App constructor.

Looks like a Silverlight bug, but all I did is checking the design time at the beginning of the constructor:

public BasePage()
{
   if (DesignerProperties.IsInDesignTool) return;
   ...
}

That’s it!

• Using Telerik RadRichTextBox
• Trying to implement it using embedded HTML browser control

It is possible to make RTL richtext working in Silverlight, but there remains one serious issue – mixed RTL and LTR support

Using Telerik RadRichTextBox
For some strange reason Telerik actually supported RTL richtext till Q2 release where they seriously messed up. If you download the Q1 2011 version, you will be able to use the RTL support without any problems. Telerik support admitted that it’s a bug, but in order to fix it, people should vote for it. Sounds weird, right?
So Telerik controls are off the table.

There is no easy way to use the native Silverlight RichTextBox to present RTL HTML, so I’ve decided to implement it using a Browser control to present the HTML.
So far it works pretty well. I can manipulate the text using Javascript calls.

Create BasePage.cs

namespace MyApp.Views
{
    public class BasePage:Page
    {
    }
}

Derive the real page from the BasePage.cs

namespace MyApp.Views
{
    public partial class NewPage: BasePage
    {
    }
}

Now if you compile the project you will get the following error:
Partial declarations of ‘MyApp.Views.NewPage’ must not specify different base classes

Here you should do two more steps:

Change the Xaml accodringly:

from:

namespace MyApp.Views
<navigation:Page x:Class="MyApp.Views.EditArticle"

           .../>
</navigation:Page>

to:

<local:BasePage x:Class="MyApp.Views.NewPage"
           xmlns:local="clr-namespace:MyApp.Views"
           .../>

</local:BasePage>

And the last important thing – Add reference to AssemblyInfo.cs

  [assembly: XmlnsDefinition("http://schemas.microsoft.com/client/2007", "MyApp.Views")]

Follow me to part 2 where we will setup the the WordPress as an issue tracking system

You might argue saying that comparing these two is like comparing jeans and socks, so lets first scope our discussion to my task, which was:
1. Saving simple objects as XML files
2. Read (deserialize) them back to Java objects.
3. Support Lists.

Simple performed just like it named – both serialization and deserialization was easy. Mapping object with annotation was very intuitive.
JAXB – After 2 hours of struggling with the configuration I have finally managed to set up my objects and map them properly. Both serialization and deserialization was easy.

The conclusion is Simple!

Step 2 – Use XJC generator to create the files

Step 1 – Turning a string to complex numbers
I used the Complex.java from Princeton.

Step 2 – Preparing the string to convolution
1. Get the numeric value of all chars in the string.
2. Flip the second (shorter) string.

Step 3 – Calculate searched string value

Step 4 – Convolve

Step 5 – Look for the value in the result

Well the idea is to use the FFT to convolve two strings and get the complexity of O(n log(n)).
