Question

I have 5 different connectionStrings in my app.config file and would like to populate a combo with these values. How can I acheve this in VB ?

Answer 1

Add a reference to the System.Configuration dll. Then you can get all connection-strings with the System.Configuration.ConfigurationManager class:

Dim allConnections = System.Configuration.ConfigurationManager.ConnectionStrings
For Each connection As ConnectionStringSettings In allConnections
    Dim connectionName = connection.Name
    Dim connectionString = allConnections(connection.Name).ConnectionString
    ddlConnections.Items.Add(connectionName)
Next

I assume that you don’t want to show the full connection string but only it’s name.
