Session 1 – jQuery with ASP.NET - JQuery is an open source JavaScript library that has a passionate following among Ajax developers. Microsoft is integrating the open source JQuery library into both the ASP.NET Web Forms and ASP.NET MVC frameworks and providing full product support. Learn how you can take advantage of JQuery to build richly interactive client-side Ajax applications when developing either ASP.NET Web Forms or ASP.NET MVC applications. Also see how JQuery works in combination with ASP.NET AJAX to provide the best framework for building Ajax applications.

Session 2 – Data Services - OnPremise and Off - In the near future, applications will be developed using a combination of custom application code and online building block services, including data-centric services. In this session we discuss advancements in the Microsoft development platform and online service interfaces to enable seamless interaction with data services both on-premises (e.g., ADO.NET Data Services Framework over on-premises SQL Server) and in the cloud (e.g., SQL Server Data Services). Learn how you can leverage existing know-how related to LINQ (Language Integrated Query), data access APIs, data-binding, and more when building applications using online data.

Session 3 – Architecting for the Cloud using Windows Azure - This session provides a tour of the Windows Azure cloud computing platform, an overview of its various components, and explains how these fit together to provide best-of-cloud experiences. We will explore the architecture that links many of the Microsoft .NET services and lets ISVs and businesses deliver compelling solutions. Learn how to compose these services with SQL Data Services to create applications in the cloud and connect them with on-premise systems. We will also examine the next generation of messaging, data, access control, and directory services, and how they fit together to provide a seamless integration into the cloud.

Uploading a Database to Dotster

Ken Tucker — Thu, 13 Mar 2008 02:39:16 GMT

The easiest way to upload a database to dotster is to use the sql hosting toolkit. Visual studio 2008 installs the sql hosting toolkit for you otherwise you need to download and install from the link.

Steps to do this

1) Create a database in the dotster control panel.

2) In the server explorer create a link to the database you want to upload.

3) Right click on the database and select publish to provider in the wizard make sure you select sql 2000 as the target database schema.

4) On the codeplex website they use to have a webpage available to use to help run the script to create your database. Now they have a webservice for this. I kind of think the webservice is over kill to just publish 1 database. So create a c# website which targets the .net framework 2.0

5) Add the script file you created in step 3 to the website.

6) Add the following code to webpage

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Text;
using System.Data.SqlClient;
using System.Web;
using System.IO;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;

namespace WebApplication3
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string fileName = Server.MapPath(@"<<YOUR_SCRIPTFILE>>.SQL");

// Connection string to the server you want to execute against
string connectionString = @"Server=<<YOUR_SERVER>>;User ID=<<YOUR_USERNAME>>;Password=<<YOUR_PASSWORD>>;Initial Catalog=<<YOUR_DATABASE>>";

// Timeout of batches (in seconds)
int timeout = 600;

            SqlConnection conn = null;
            try
            {
                Response.Write(String.Format("Opening file {0}<BR>", fileName));

                // read file
                using (StreamReader sr = new StreamReader(new FileStream(fileName, FileMode.Open)))
                {
                    Response.Write("Connecting to SQL Server database...<BR>");

// Create new connection to database
conn = new SqlConnection(connectionString);

conn.Open();

                    while (!sr.EndOfStream)
                    {
                        StringBuilder sb = new StringBuilder();
                        SqlCommand cmd = conn.CreateCommand();

                        while (!sr.EndOfStream)
                        {
                            string s = sr.ReadLine();
                            if (s != null && s.ToUpper().Trim().Equals("GO"))
                            {
                                break;
                            }

sb.AppendLine(s);
}

                        // Execute T-SQL against the target database
                        try
                        {
                            cmd.CommandText = sb.ToString();
                            cmd.CommandTimeout = timeout;

cmd.ExecuteNonQuery();

                        }
                        catch (Exception ex)
                        {
                            Response.Write(sb.ToString().Replace("\n", @"<br/>"));
                            Response.Write(ex.Message.ToString() + @"<br />");
                        }
                    }

                }
                Response.Write("T-SQL file executed successfully");
            }
            catch (Exception ex)
            {
                Response.Write(String.Format("An error occured: {0}", ex.ToString()));
            }
            finally
            {
                // Close out the connection
                //
                if (conn != null)
                {
                    try
                    {
                        conn.Close();
                        conn.Dispose();
                    }
                    catch (Exception e1)
                    {
                        Response.Write(String.Format(@"Could not close the connection. Error was {0}", e1.ToString()));
                    }
                }
            }

}
}
}

Uploasd the website to dotster and open the webpage and your database should be copied to the new database. Make sure you delete the website after you created the database to prevent someone from accidently undo changes to the database after you uploaded it.

Using XLinq to get a list of Photos from Spaces.Live.com

Ken Tucker — Sun, 16 Sep 2007 19:39:49 GMT

Using XLinq to get a list of Photos from Spaces.Live.com

Storing photo albums on line is becoming very popular. Spaces.Live.com photo is one place to store albums which exposes its photo albums via an rss feed. I thought it would be nice to test out Visual Studio 2008 XLinq by getting a list of Photo's from the Tampa Code Camp and display them in WPF Listbox.

The photos I am looking for can be found here.

http://thedevfish.spaces.live.com/photos/cns!75364D9E73295107!133/feed.rss

The xml in the rss feed exposes each photo like this

    </item>

Lets query the xml feed and get the title for the photo and convert the quid to a link for the photo. The link is http://storage.live.com/items/PictureId. The guid gives us cns!pictureId so we need to replace cns! with http://storage.live.com/items/

    Private Sub Window1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated
        Dim strUrl As String = "http://thedevfish.spaces.live.com/photos/cns!75364D9E73295107!133/feed.rss "
        Dim feeds = XElement.Load(strUrl)

        Dim query = From p In feeds.Element("channel").Elements("item") _
                  Select title = p.Element("title").Value, link = p.Element("guid").Value.ToString.Replace("cns!", "http://storage.live.com/items/")

        lstPhotos.ItemsSource = query.ToList
    End Sub
End Class

Nested GridViews

Ken Tucker — Sun, 16 Sep 2007 19:27:46 GMT

Nested GridViews

In this example we are going to display the orders and its details from the Northwind database in one GridView. In an TemplateField place a GridView which calls a function to get the child records.
