Visual Studio 2012 VB.NET - Change SQL connection dynamically

Posted on 2013-06-13

I have an application that is connected to two SQL Server databases, however I dynamically need to change one of the SQL connections to other databases on the fly.  The databases have exactly the same database scheme and are located on the same SQL Server.

It appears that most of the database connections are read-only and can't be changed.  Is it possible to update this?

why can't you create new SqlConnection object?

Dim SQLConn As SqlConnection = New SqlConnection
SQLConn.ConnectionString = "Data Source=servername;" & _
"Initial Catalog=databasename;" & _
"User ID=username;" & _
"Password=userpassword;"

Open in new window

you cannot change the connection of currently opened objects. If you change your connection, you need to create new objects
