{
class Program
{
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
Imports System.Collections.Generic

Imports Microsoft.SqlServer.Dts.Runtime
Namespace Package_API
Class Program
Shared Sub Main(ByVal args() As String)
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)
End Sub
End Class
