No changes required in connection string. Because connection strings contains the database name and where it reside does not matter for calling application.

E.g. If you were working with MSDE 2000 you have a server name, probably (local), and no instance name. In this case myServerAddress=(local)

If you are working with SQL Server 2005 express edition, you have a server name and a named instance, having installed using the defaults, the server name would be the name of your computer and the instance name would be SQLEXPRESS (or something similar), so myServerAddress=PCName\SQLEXPRESS

can you help me?

Then you can call in your code.

Dim myconnstring As String = My.Settings.STIConnectionstring

Dim sconn As New SqlConnection With {.ConnectionString = myconnstring}

Good Day..

I have code working on mysql Connection Strings For .NET. But now that code i want switch on Connection Strings For .NET and MsSql 2005 & .NET 2008 for a Client Server.

This is my sample code working to mysql server:

Imports MySql.Data.MySqlClient
Imports System.Configuration

Public Class MySQLDBAccess
#Region “Private Shared Variables”
Private Shared mySqlConnString As String = String.Empty ‘MySQL Connection String
Private Shared mySqlConn As New MySqlConnection ‘MySQL Connection
Private Shared mySqlCommand As New MySqlCommand ‘MySQL Command
Private Shared mySqlDataAdapter As New MySqlDataAdapter ‘MySQL Data Adapter
Private Shared mySqlDataReader As MySqlDataReader ‘MySQL Data Reader

#End Region

‘For Testing Database Connection
Public Shared Sub TestMySQLDBConnection(ByRef strErrMsg As String)

Try
mySqlConn = New MySqlConnection()
mySqlConn.ConnectionString = mySqlConnString

mySqlConn.Open()
mySqlConn.Close()
Catch ex As Exception
strErrMsg = “Cannot connect to DiabNet database.”
DBL_PRINTLOG(“MySQLDBAccess::TestMySQLDBConnection() >> ” & ex.Message)
End Try

End Sub

End Class

Private Sub btnTestConnection_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTestConnection.Click
Dim strErrMsg As String = String.Empty
Dim RptString As String = String.Empty

Try
MySQLDBAccess.connectionString = “server = ” & txtServer.Text & “;” _
& “user id = ” & txtUserID.Text & “;” _
& “password = ” & txtPassword.Text & “;” _
& “database = ” & txtDatabase.Text & “;” _
& “Allow Zero Datetime=true;”

MySQLDBAccess.TestMySQLDBConnection(strErrMsg)

If strErrMsg = String.Empty Then
‘Write DB Connection Setting to app.config
WriteDBConfig(MySQLDBAccess.connectionString)
MessageBox.Show(“Test connection successful.”, “DiabNet DB Connection”, MessageBoxButtons.OK, MessageBoxIcon.Information)
btnOK.Enabled = True
Else
MessageBox.Show(strErrMsg, “DiabNet DB Connection”, MessageBoxButtons.OK, MessageBoxIcon.Information)
End If
Catch ex As Exception
DBL_PRINTLOG(“DS_frmDatabaseSettings::btnTestConnection_Click() Exception >> ” & ex.Message)
End Try
End Sub

Please help me how to change my connection String from mysql to Mssql 2005 & Vs2008. ASAP!

Thank and Advanced..
