MS SQL Server Express connection error from VB.net Program

I am trying to make new connection with SQL Server 2005 Express Database fro
m
my Visual Basic.Net program. I am using connection string as "Dim
connectionString As String = "Data Source=.\SQLEXPRESS;Initial
Catalog=MgmtSystem;User Instance=True".
But it is giving me error as " Failed to generate a user instance of SQL
Server. Only integrated connection can generate a User Instance".
I can connect to this "MgmtSystem" database successfully using Microsoft SQL
Server Management Studio Express though.
What could be the possible reason for this error? How do I get the correct
connection string? and what does integrated connection mean? Your help will
be appreciated.
My application is in Access at the moment, but I am planning to migrate it
to Microsoft SQL Server Express 2005. I am completely new to Microsoft SQL
Server Express 2005 Express version.Fixed it by myself. I changed the connectiuon string to "Data
Source=.\SQLEXPRESS;AttachDbFilename=C:\Program Files\Microsoft SQL
Server\MSSQL.1\MSSQL\Data\MgmtSystem.mdf;Initial Catalog=MgmtSystem;Persist
Security Info=True;" ..and it worked..
