Замечания

Component developers can provide a user interface for a data flow component by specifying a Type and implementing this interface in the UITypeName property of the DtsPipelineComponentAttribute attribute. The designer calls the methods of this interface when the component is added, deleted, and edited inside the SSIS Designer.

Примеры

The following code sample demonstrates a class that implements the IdtsComponentUI interface. For more information and the complete sample, see Разработка пользовательского интерфейса для компонента потока данных.

using System.Windows.Forms;
using Microsoft.SqlServer.Dts.Runtime;
using Microsoft.SqlServer.Dts.Pipeline.Design;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;

namespace Microsoft.Samples.SqlServer.Dts
{
    public class SampleComponentUI : IDtsComponentUI
    {
        IDTSComponentMetaData100 md;
        IServiceProvider sp;

        public void Help(System.Windows.Forms.IWin32Window parentWindow)
        {
        }

        {

        public void Delete(System.Windows.Forms.IWin32Window parentWindow)
        {
        }
        public bool Edit(System.Windows.Forms.IWin32Window parentWindow, Variables vars, Connections cons)
        {

            SampleComponentUIForm componentEditor = new SampleComponentUIForm(cons, vars, md);

            DialogResult result  = componentEditor.ShowDialog(parentWindow);

            if (result == DialogResult.OK)
