Artikkeli
12/03/2008

Gets the IDTSComponentView90 interface for a component, which supports transactional edits of the component metadata.

Namespace: Microsoft.SqlServer.Dts.Pipeline.Wrapper
Assembly: Microsoft.SqlServer.DTSPipelineWrap (in microsoft.sqlserver.dtspipelinewrap.dll)

Syntax

'Declaration
<DispIdAttribute(119)> _
Function GetComponentView As IDTSComponentView90

[DispIdAttribute(119)] 
IDTSComponentView90 GetComponentView ()

[DispIdAttribute(119)] 
IDTSComponentView90^ GetComponentView ()

/** @attribute DispIdAttribute(119) */ 
IDTSComponentView90 GetComponentView ()

DispIdAttribute(119) 
function GetComponentView () : IDTSComponentView90

Return Value

The IDTSComponentView90 interface of the component.

Remarks

This method is called to retrieve the IDTSComponentView90 interface of the component. This interface allows transactional modifications to be made to the component metadata. The component metadata modifications are persisted when the Commit method is called, and reverted when the Cancel method is called.

Example

The following code example demonstrates how the GetComponentView method is used.

using System;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;

namespace Microsoft.Samples.SqlServer.Dts
{
    public class Class1
    {
        public static void Main(string []args)
        {
            // Create the package.
            Package p = new Package();

            // Add the data flow task.
            MainPipe mp = ((TaskHost)p.Executables.Add("DTS.Pipeline")).InnerObject as MainPipe;

            // Add the OLEDB Source component.
            IDTSComponentMetaData90 mdOleDbSrc = mp.ComponentMetaDataCollection.New();
            mdOleDbSrc.ComponentClassID = "DTSAdapter.OleDbSource";
            mdOleDbSrc.Name = "OLEDB Source";

            IDTSComponentView90 oledbView = mdOleDbSrc.GetComponentView();

            mdOleDbSrc.Name = "The OLEDB Source Component";

            Console.WriteLine(mdOleDbSrc.Name);

            oledbView.Cancel();

            Console.WriteLine(mdOleDbSrc.Name);
        }
    }
}

Imports System 
Imports Microsoft.SqlServer.Dts.Runtime 
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper 
Namespace Microsoft.Samples.SqlServer.Dts 

 Public Class Class1 

   Public Shared Sub Main(ByVal args As String()) 
     Dim p As Package = New Package 
     Dim mp As MainPipe = CType(CType(p.Executables.Add("DTS.Pipeline").InnerObject, TaskHost), MainPipe)
     Dim mdOleDbSrc As IDTSComponentMetaData90 = mp.ComponentMetaDataCollection.New 
     mdOleDbSrc.ComponentClassID = "DTSAdapter.OleDbSource" 
     mdOleDbSrc.Name = "OLEDB Source" 
     Dim oledbView As IDTSComponentView90 = mdOleDbSrc.GetComponentView 
     mdOleDbSrc.Name = "The OLEDB Source Component" 
     Console.WriteLine(mdOleDbSrc.Name) 
     oledbView.Cancel 
     Console.WriteLine(mdOleDbSrc.Name) 
   End Sub 
 End Class 
End Namespace

The following output is generated by the above code example.
