Examples

The following code example sets the CheckpointUsage property.

using System;  
using System.Collections.Generic;  
using System.Text;  
using Microsoft.SqlServer.Dts.Runtime;  
  
namespace Package_API  
{  
    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 System.Text  
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  
End Namespace  

Sample Output:

Check for existing checkpoint file? IfExists

Remarks

The default value of this property is Never, which indicates that the package cannot be restarted. For more information about the use of checkpoints in a package, see Restart Packages by Using Checkpoints.
