Notes
The ReinitializeMetaData method is called in response to a component returning VS_NEEDSNEWMETADATA from Validate. During this method, components fix any errors that were identified in Validate, if those errors can be fixed by the component.
Exemple
The following example calls ReinitializeMetaData in response to a component failing validation.
Package p = new Package();
MainPipe dataFlow = ((TaskHost)p.Executables.Add("DTS.Pipeline")).InnerObject as MainPipe;
IDTSComponentMetaData90 md = dataFlow.ComponentMetaDataCollection.New();
md.ComponentClassID = "DTSAdapter.OleDbSource";
CManagedComponentWrapper wrp = md.Instantiate();
wrp.ProvideComponentProperties();
if (wrp.Validate() == DTSValidationStatus.VS_NEEDSNEWMETADATA)
{
wrp.ReinitializeMetaData();
}
Dim p As Package = New Package
Dim dataFlow As MainPipe = CType(CType(p.Executables.Add("DTS.Pipeline"), TaskHost).InnerObject, MainPipe)
Dim md As IDTSComponentMetaData90 = dataFlow.ComponentMetaDataCollection.New
md.ComponentClassID = "DTSAdapter.OleDbSource"
Dim wrp As CManagedComponentWrapper = md.Instantiate
wrp.ProvideComponentProperties
If wrp.Validate = DTSValidationStatus.VS_NEEDSNEWMETADATA Then
wrp.ReinitializeMetaData
End If
