Notes

Path objects are created to establish the flow of data between the IDTSOutput100 of an upstream component and the IDTSInput100 of another component. A path contains a single output object represented as the StartPoint, and a single input, which is the EndPoint of the path. A path between two components is established in a two-step process. First, create the path by calling New on the path collection of the IDTSComponentMetaData100 object. Second, establish the path by calling AttachPathAndPropagateNotifications on the path itself. This method establishes the path and notifies the affected components of its existence.

The columns of the StartPoint are subsequently mapped to the EndPoint by calling SetUsageType.

Exemples

The following code example demonstrates how to create a new IDTSPath100 object, and then attach the output of the upstream component to the input of the downstream component.

public IDTSPath100 EstablishPath( MainPipe mp , IDTSOutput100 start , IDTSInput100 end )
{
IDTSPath100 path = mp.PathCollection.New();
path.AttachPathAndPropagateNotifications( start, end );
return path;
}
Public Function EstablishPath(ByVal mp As MainPipe, ByVal start As IDTSOutput100, ByVal end As IDTSInput100) As IDTSPath100 
 Dim path As IDTSPath100 = mp.PathCollection.New 
 path.AttachPathAndPropagateNotifications(start, end) 
 Return path 
End Function
