        static void Main(string[] args)
        {
                    Application app = new Application();
            Package pkg = new Package();
            pkg = app.LoadPackage(@"C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx", null);

            // Set the CheckpointUsage to IfExistts to force package to retart if
            // the file specified by the CheckpointFileName property is found.
            pkg.CheckpointUsage = DTSCheckpointUsage.IfExists;

            Console.WriteLine("Check for existing checkpoint file? {0}", pkg.CheckpointUsage);
        }
    }
}

Imports System

                    Dim app As Application =  New Application() 
            Dim pkg As Package =  New Package() 
            pkg = app.LoadPackage("C:\Program Files\Microsoft SQL Server\100\Samples\Integration Services\Package Samples\CalculatedColumns Sample\CalculatedColumns\CalculatedColumns.dtsx", Nothing)
 
            ' Set the CheckpointUsage to IfExistts to force package to retart if
            ' the file specified by the CheckpointFileName property is found.
            pkg.CheckpointUsage = DTSCheckpointUsage.IfExists
 
            Console.WriteLine("Check for existing checkpoint file? {0}", pkg.CheckpointUsage)
