Hi JorgeEnciso-6991,

Please try the following.

VB.NET

Sub Main
    Const FILENAME As String = "e:\temp\file_ADO.NET.VB.xml"

    Dim builder As SqlConnectionStringBuilder = New SqlConnectionStringBuilder()
    builder.DataSource = "SPACESHIP,1433"
    builder.InitialCatalog = "AdventureWorks2012"
    builder.IntegratedSecurity = True
    builder.ApplicationName = "Wonderful application"
    builder.NetworkLibrary = "dbmssocn"
    builder.PacketSize = 32768

    Using con As SqlConnection = New SqlConnection(builder.ConnectionString)
        Using cmd As SqlCommand = New SqlCommand()
            cmd.Connection = con
            cmd.CommandType = CommandType.Text
            cmd.CommandText = "SELECT TOP(2) * FROM Person.Person FOR XML PATH('r'), TYPE, ROOT('root')"
            con.Open()

            Using reader As XmlReader = cmd.ExecuteXmlReader()
                Dim xdoc As XDocument = XDocument.Load(reader)
                Dim settings = New XmlWriterSettings()
                settings.Indent = True
                settings.OmitXmlDeclaration = False
                settings.IndentChars = Microsoft.VisualBasic.Constants.vbTab
                settings.Encoding = New UTF8Encoding(False)

                Using writer = XmlWriter.Create(FILENAME, settings)
                    xdoc.Save(writer)
                End Using
            End Using

            Console.WriteLine("File '{0}' has been created.", FILENAME)
        End Using
    End Using
End Sub

Answer 4

Is igfnav03 a SQL Server instance on your local machine or the network?

Is Windows auth enabled on the SQL Server?

In SSMS does it show that your user account has permissions to access the Test Navision database?

Your tag includes Azure SQL. To connect to SQL Azure using Win auth you have to properly enable AD integration (which requires infrastructure support) and you must use AAD integration.

Answer 5

Connection string values may optionally be enclosed in single or double quotes but not square brackets. There is no need to enclose the database name value in this case:

Dim conString1 As String = "Data Source=igfnav03; Initial Catalog=Test Navision; integrated Security=true"
