Metodo IDTSDesigntimeComponent100.ReinitializeMetaData
Fixes any errors identified during design-time validation that result in the component returning VS_NEEDSNEWMETADATA.

Osservazioni
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.
Esempi
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;
IDTSComponentMetaData100 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 IDTSComponentMetaData100 = 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
