SQL Server Express XCOPY

The XCOPY feature of SQL Server Express is a good feature which would help applications to deploy databases very easily.
This is similar to deploying Microsoft Access databases

Sample code from the 101 VB samples (VB101SamplesWinForms\UsingDataGridView)
on how to connect to MDF files have been added
======================================================
Dim connectStringBuilder As New SqlConnectionStringBuilder()
connectStringBuilder.DataSource = ".\SQLEXPRESS"
connectStringBuilder.AttachDBFilename = "C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\AdventureWorks_Data.mdf"
connectStringBuilder.IntegratedSecurity = True
connectStringBuilder.UserInstance = True
==========================================
Some very good links are as follows:

• http://weblogs.asp.net/jackieg/archive/2004/07/23/192255.aspx. Jackie's link also contains a link on how XCOPY works. This is also a good read
• http://msdn2.microsoft.com/en-us/library/ms165716.aspx . Also the named instances portion of the article is important
• http://msdn2.microsoft.com/en-us/library/ms143684.aspx has an article on User Instances. When we are setting the User Instance in the connection string to TRUE, we are using User Instances

Asynchronous Tasks in .NET 2.0

In .NET 2.0, a new class BackgroundWorker Class has been introduced.
This would help in Asynchronous Tasks.
These are paricularly helpful when there is a long running task such as downloading a file,uploading a file,printing a large number of documents.

Good links are as follows:
