    {
    // if our factory supports creating a DbConnection, return it.
    if ((factory.SupportedClasses & DbProviderSupportedClasses.DbConnection) > 0)
      return factory.CreateConnection();
    else
      return null;
    }
    Public Function GetConnectionBaseClass2(ByVal factory As DbProviderFactory) As DbConnection
      'if our factory supports creating a DbConnection, return it.
      If ((factory.SupportedClasses And DbProviderSupportedClasses.DbConnection) > 0) Then
        Return factory.CreateConnection()
