Exemples

L’exemple de code suivant montre comment la méthode GetComponentView est utilisée.

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 IDTSComponentMetaData100 = mp.ComponentMetaDataCollection.New   
     mdOleDbSrc.ComponentClassID = "DTSAdapter.OleDbSource"   
     mdOleDbSrc.Name = "OLEDB Source"   
     Dim oledbView As IDTSComponentView100 = mdOleDbSrc.GetComponentView   
     mdOleDbSrc.Name = "The OLEDB Source Component"   
     Console.WriteLine(mdOleDbSrc.Name)   
     oledbView.Cancel   
     Console.WriteLine(mdOleDbSrc.Name)   
   End Sub   
 End Class   
End Namespace  

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.  
            IDTSComponentMetaData100 mdOleDbSrc = mp.ComponentMetaDataCollection.New();  
            mdOleDbSrc.ComponentClassID = "DTSAdapter.OleDbSource";  
            mdOleDbSrc.Name = "OLEDB Source";  

            IDTSComponentView100 oledbView = mdOleDbSrc.GetComponentView();  

            mdOleDbSrc.Name = "The OLEDB Source Component";  

            Console.WriteLine(mdOleDbSrc.Name);  

            oledbView.Cancel();  

            Console.WriteLine(mdOleDbSrc.Name);  
        }  
    }  
}  
The following output is generated by the above code example.  
The OLEDB Source Component  
OLEDB Source  

Remarques

Cette méthode est appelée pour récupérer l’interface IDTSComponentView100 du composant. Cette interface permet d’apporter des modifications transactionnelles aux métadonnées du composant. Les modifications des métadonnées de composant sont conservées lorsque la Commit méthode est appelée et rétablie lorsque la Cancel méthode est appelée.
