IDTSDesigntimeComponent90.ReinitializeMetaData Method

  • 项目

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

命名空间: Microsoft.SqlServer.Dts.Pipeline.Wrapper
程序集: Microsoft.SqlServer.DTSPipelineWrap (in microsoft.sqlserver.dtspipelinewrap.dll)

语法

声明
<DispIdAttribute(12)> _
Sub ReinitializeMetaData

[DispIdAttribute(12)] 
void ReinitializeMetaData ()

[DispIdAttribute(12)] 
void ReinitializeMetaData ()

/** @attribute DispIdAttribute(12) */ 
void ReinitializeMetaData ()

DispIdAttribute(12) 
function ReinitializeMetaData ()

备注

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.

示例

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
