I tried it on with Visual Studio 2010 and MS SQL Server 2008 R2 express. I received error on line 49 “cmd.CommandType = CommandType.StoredProcedure;”

The error says ” the name ‘CommandType’ does not exit in the current context.
7 warnings in Web.config says, “Could not find schema information for the elecment ‘appsettings’.

Any suggetions?

Hi, Amy
If you want the output to a xml file instead of on screen, you simply modify XmlTextWriter object on line 31.

From

XmlTextWriter xml = new XmlTextWriter(Response.OutputStream, Encoding.UTF8);

XmlTextWriter xmlWriter = new XmlTextWriter(xmlFilePath, Encoding.UTF8);

where xmlFilePath is the file destination.

Thank you for this!!

My only question is how can I alter it so that it writes to a file like myrss.xml?

Yes, you can do that. First, you modify your store procedure to get an additional column (the ID column) that you want. Then, modify the code on step 8 from
xml.WriteElementString(“link”, reader[3].ToString());
to
xml.WriteElementString(“link”, reader[3].ToString() + “?id=” + reader[5].ToString());
(Assume that the column ID’s index is 5)

Hi linglom, sorry you must have miss understood. i need the value to come from the database as well so, if i had the link and the id in the database is there a way that i could pull them both together so i get the web address http://localhost/CS09/getimage.asp?id= and then the ID, 10
which will make http://localhost/CS09/getimage.asp?id=10

Hi, Max Allen
Yes, if you want to add a parameter to url, you can add on the end of the text value.

xml.WriteElementString(“link”, “http://localhost/index.php?id=10″);

wondering if anyone can help here. i have followed everything on the site and all works fine. what i am trying to do is to add another value in to the reader so when you click on the link it brings you to the website with a value on it need the extra code to add on to the end
xml.WriteElementString(“link”, “http://localhost/CS09/getimage.asp?id=”)????????

is this possible ?

I followed your article, but made some changes: with this code, you can publish more than 1 “item”

protected void Page_Load(object sender, EventArgs e)
{
Response.Clear();
Response.ContentType = “text/xml”;

XmlTextWriter xml = new XmlTextWriter(Response.OutputStream, Encoding.UTF8);
xml.WriteStartDocument();

xml.WriteStartElement(“rss”);
xml.WriteAttributeString(“version”, “2.0″);

xml.WriteStartElement(“channel”);
xml.WriteElementString(“title”, “Test RSS Feed”);
xml.WriteElementString(“link”, “http://testLink”);
xml.WriteElementString(“description”, “This is example Feed from SQL Server”);
xml.WriteElementString(“copyright”, “Copyright 2008. All rights reserved.”);
try
{
SqlConnection myConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["Users_Form_Data"].ToString());
SqlCommand myCommand = myConnection.CreateCommand();
myCommand.CommandText = “SELECT * FROM feeds ORDER BY date”;
SqlDataAdapter myAdapter = new SqlDataAdapter(myCommand);

DataSet mySet = new DataSet();
myAdapter.Fill(mySet);

foreach (DataRow myRow in mySet.Tables["feeds"].Rows)
{
xml.WriteStartElement(“item”);
xml.WriteElementString(“title”, myRow["title"].ToString());
xml.WriteElementString(“description”, myRow["desc"].ToString());
xml.WriteElementString(“link”, myRow["link"].ToString());
xml.WriteElementString(“pubDate”, myRow["date"].ToString());
xml.WriteEndElement();

}
}
catch { Response.Write(“We are currenly experiencing Technical Difficulties”); }
xml.WriteEndElement();
xml.WriteEndElement();
xml.WriteEndDocument();
xml.Flush();
xml.Close();
Response.End();
}
