주의

This interface is one of two interfaces implemented by data flow components; IDTSRuntimeComponent100 is the other. This interface defines the design-time interface for a component and contains methods that are called when the component properties and collections of the ComponentMetaData are modified. Managed component developers do not explicitly implement this interface, and instead use the PipelineComponent base class, which implements the methods of both these interfaces.

When programmatically adding or modifying existing components in a data flow task, the design-time instance of a component should be used instead of accessing the component metadata directly. Modifying the ComponentMetaData directly bypasses the ability of the component to validate and reject changes to its metadata, and should be avoided. Managed code developers access the design-time instance of a component, and use the methods of the IDTSDesigntimeComponent100 interface, through the CManagedComponentWrapper.

예

The following code example demonstrates how to access the design-time instance of a component.

Package p = new Package();
MainPipe dataFlow = ((TaskHost)p.Executables.Add("DTS.Pipeline")).InnerObject as MainPipe;

IDTSComponentMetaData100 md = dataFlow.ComponentMetaDataCollection.New();
md.ComponentClassID = "DTSAdapter.OleDbSource";
CManagedComponentWrapper wrp = md.Instantiate();
wrp.ProvideComponentProperties();

Dim p As Package = New Package 
Dim dataFlow As MainPipe = CType(CType(p.Executables.Add("DTS.Pipeline"), TaskHost).InnerObject, MainPipe) 
Dim md As IDTSComponentMetaData100 = dataFlow.ComponentMetaDataCollection.New 
md.ComponentClassID = "DTSAdapter.OleDbSource" 
Dim wrp As CManagedComponentWrapper = md.Instantiate 
wrp.ProvideComponentProperties
