Remarks
Updated sample code:17 July 2006

Example
The following code example is a very simple task implementation for a custom task that inherits from Task.
using System;
using Microsoft.SqlServer.Dts.Runtime;
class MyTask : Task
{
private int m_value = 123;
public override DTExecResult Execute(Connections connections,
Variables variables, IDTSEvents events,
IDTSLogging log, int lastExecResult, DtsTransaction txn)
{
return m_value;
}
}
Imports System
Imports Microsoft.SqlServer.Dts.Runtime
Class MyTask
Inherits Task
Private m_value As Integer = 123
Public Overrides DTExecResult Property connections,() As Execute(Connections
End Property
Variables variables, IDTSEvents events,
IDTSLogging log,int Function txn)() As lastExecResult,DtsTransaction
Return m_value
End Function
End Class
