Exception from HRESULT: 0xC020801C getting this error while trying to execute programitically built SSIS package

Hi experts,


I'm developing a SSIS package programitically using C#.net, every thing is fine til i acquire the connection, i'm struck here, i'm getting COM exception i.e HRESULT: 0xC020801C, i went through many threads but i could not find any proper solution, so i'm posting this query again, i need the solution badly.

here goes my code...


PipeLineWrapper.CManagedComponentWrapper managedOleInstance = managedOleInstanceDestinationComponent;
            // setting the connection
            if (destinationComponent.RuntimeConnectionCollection.Count > 0)
            {   // If connection is necessary
                destinationComponent.RuntimeConnectionCollection[0].ConnectionManagerID =
                    destinationDatabaseConnectionManager.ID;
                destinationComponent.RuntimeConnectionCollection[0].ConnectionManager =
                                DtsConvert.ToConnectionManager90(destinationDatabaseConnectionManager);

            }
            // Set the custom properties.
            managedOleInstance.SetComponentProperty("AccessMode", 0);                  
            managedOleInstance.SetComponentProperty("AlwaysUseDefaultCodePage", false); 
            managedOleInstance.SetComponentProperty("DefaultCodePage", 1252);          
            managedOleInstance.SetComponentProperty("FastLoadKeepIdentity", false);    
            managedOleInstance.SetComponentProperty("FastLoadKeepNulls", false);
            managedOleInstance.SetComponentProperty("FastLoadMaxInsertCommitSize", 0);
            managedOleInstance.SetComponentProperty("FastLoadOptions", "TABLOCK,CHECK_CONSTRAINTS");
            managedOleInstance.SetComponentProperty("OpenRowset",
                string.Format("[{0}].[dbo].[{1}]", DatabaseName, TableName));

            // Now activate a connection and create the mappings
            // =========================================================================
            // Establish a connection
            managedOleInstance.AcquireConnections(null);         --------------------------> this is the point where i'm getting the exception
            // initialize the metadata
            managedOleInstance.ReinitializeMetaData();
            // Get the destination's default input and virtual input.
            PipeLineWrapper.IDTSInput90 input = destinationComponent.InputCollection[0];
            PipeLineWrapper.IDTSVirtualInput90 vInput = input.GetVirtualInput();


i'm using csv file as sourece and sql server as destination, sql server is running in the local system  here goes my connection string
