An existing database may be added or imported to a session by calling the CTSession::AddDatabase() method. Use CTSession::AddDatabase() to add an existing database to the current session. CTSession::AddDatabase() takes a database name and the path where the database is located.
// add MyDatabase to the current session
try
{
ASession.AddDatabase("MyDatabase", "");
}
catch (CTException &err)
{
printf("Add database failed with error %d\n", err.GetErrorCode());
}
