0 down vote favorite I am trying to implement a custom data flow component in my managed code. Here is my custom data flow component: [DtsPipelineComponent(DisplayName = "RenameComponent", ComponentType = ComponentType.Transform)] public class MapperComponent : PipelineComponent { List<idtsvirtualinputcolumn100>dontMapList; public override void ProvideComponentProperties() { base.ProvideComponentProperties(); base.RemoveAllInputsOutputsAndCustomProperties(); IDTSInput100 input = ComponentMetaData.InputCollection.New(); input.Name = "Input"; IDTSOutput100 output = ComponentMetaData.OutputCollection.New(); output.Name = "Output"; output.SynchronousInputID = input.ID; // Make the output asynchronous output.SynchronousInputID = 0; FindOldColumns(input); } } I compile that, register it with the gac, and save it to the C:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents directory. I then run the following code to add the component to my data flow task: private static IDTSComponentMetaData100 CreateRenameTransformation(MainPipe dataFlow, Train train) { IDTSComponentMetaData100 renameTransformation = dataFlow.ComponentMetaDataCollection.New(); // Set stock properties renameTransformation.ComponentClassID = "Dexter.CustomComponents.MapperComponent"; renameTransformation.Name = "RenameTransformation"; renameTransformation.Description = "Rename and remove incompatible columns"; CManagedComponentWrapper instance = renameTransformation.Instantiate(); instance.ProvideComponentProperties(); return renameTransformation as IDTSComponentMetaData100; } During runtime (when i try to create the pacakge), I get the following error: 0xC0048021 -1073446879 DTS_E_ERRORCOMPONENT The component is missing, not registered, not upgradeable, or missing required interfaces. The contact information for this component is "%1". Thanks,</idtsvirtualinputcolumn100>-DF

Hi Gaurav_X, The error 0xC0048021 means that the component is not installed basically, the ComponentClassID you are using is not right as you suspect, please refer to the componentClassId for Integration Services: http://sqlblogcasts.com/blogs/simons/archive/2007/01/05/ComponentClassId-for-Integration-Services.aspx And here is a similar thread, please refer to: http://social.msdn.microsoft.com/forums/en-US/sqlintegrationservices/thread/46bdf95f-5f15-4f2f-af7c-09f506aa4e6d/ Thanks, Eileen TechNet Subscriber Support If you are TechNet Subscription user and have any feedback on our support quality, please send your feedback here.
