Creating an RSS Aggregator User Control in ASP.NET

, 2 Mar 2006
This article demonstrates how to easily create an RSS feed aggregator and incorporate it into an ASP.NET application.
<?xml version="1.0" encoding="utf-8"?>
    Microsoft ResX Schema 
    Version 1.3
    The primary goals of this format is to allow a simple XML format 
    that is mostly human readable. The generation and parsing of the 
    various data types are done through the TypeConverter classes 
    associated with the data types.
    ... headers & schema ...
    <resheader name="resmimetype">text/microsoft-resx</resheader>
    <resheader name="version">1.3</resheader>
    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
    <data name="Name1">this is my long string</data>
    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
    <data name="Bitmap1" mimetype="application/">
        [base64 mime encoded serialized .NET Framework object]
    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/">
        [base64 mime encoded string representing a byte array form of the .NET Framework object]
    There are any number of "resheader" rows that contain simple 
    name/value pairs.
    Each data row contains a name, and value. The row also contains a 
    type or mimetype. Type corresponds to a .NET class that support 
    text/value conversion through the TypeConverter architecture. 
    Classes that don't support this are serialized and stored with the 
    mimetype set.
    The mimetype is used forserialized objects, and tells the 
    ResXResourceReader how to depersist the object. This is currently not 
    extensible. For a given mimetype the value must be set accordingly:
    Note - application/ is the format 
    that the ResXResourceWriter will generate, however the reader can 
    read any of the formats listed below.
    mimetype: application/
    value   : The object must be serialized with 
            : System.Serialization.Formatters.Binary.BinaryFormatter
            : and then encoded with base64 encoding.
    mimetype: application/
    value   : The object must be serialized with 
            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
            : and then encoded with base64 encoding.

    mimetype: application/
    value   : The object must be serialized into a byte array 
            : using a System.ComponentModel.TypeConverter
            : and then encoded with base64 encoding.
