RSS Widget 2 In Silverlight 3 with Data Persistence

Introduction

This is a new Version of my old RSS Widget Article. As you will see it has the feature of data persistence using ISO Storage.

Creating the Silverlight Project

We will create a simple Silverlight Project and name it asRSSFeedWidget2.

Designing our Sample Application

I have used Blend 3 to design our simple application. I have kept one TextBox where the user can paste the RSS Feed URL and two buttons, one for search feed data and the other one for adding the URL into persistence (ISO Storage). I have used three png images to accomplish my design.

Checking for RSS URL in Persistence

When the User control will be loaded, it will check the availability of the key and if present it would display the RSS Data, Otherwise it would give exception as no key found. The following code will achieve our goal.

Objective The objective of this article is to demonstrate a socket-based client/server application that will allow two-way asynchronous communication between a server and multiple client applications. Because this example uses asynchronous methods, the server application does not use threads to communicate to multiple clients (although internally the asynchronous communication mechanism uses threads at the OS level). The Difference Between Synchronous and Asynchronous Communication in Network Programming The key difference between synchronous and asynchronous communication can be explained with an example. Consider a server application that is listening on a specific port to get data from clients. In synchronous receiving, while the server is waiting to receive data from a client, if the stream is empty the main thread will block until the request for data is satisfied. Hence, the server cannot do anything else until it receives data from the client. If another clien
