1. connect to two or three server on the same time (llblgenpro - data adapter)

2. May I have code for change connection string in code but not change in config file (xxx.config)

1. LLBLGen uses ADO.Net under the hood. Each adapter can only be connected to one server. However, multiple adapters can participate in a COM+ Enterprise transaction using a ComPlusAdapterContext. (see manual)

2. The connection string can be specified in runtime in the constructor of an adapter object.

Dim ConnectionString as string = "Server=(local);Database=Northwind;Trusted_Connection=true"
Dim adapter As SD.LLBLGen.Pro.ORMSupportClasses.IDataAccessAdapter = New DatabaseSpecific.DataAccessAdapter(ConnectionString)
