execute stored procedure from Script Task

How do I execute a stored procedure in a script task using vb.net?  I'd like to use a script task as opposed to an execute sql task because I have conditional logic and I have lots of input parameters.

I'm using the code below but receive this error when calling the sub:

Unable to cast COM object of type 'System.__ComObject' to class type 'System.Data.SqlClient.SqlConnection'. Instances of types that represent COM components cannot be cast to types that do not represent COM components; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface.



 Public Sub fRunStoredProc()
        Dim cn As SqlConnection = DirectCast(Dts.Connections("MyConnection").AcquireConnection(Nothing), SqlConnection)
        Dim cmd As SqlCommand

        cn.Open()
        cmd.Connection = cn
        cmd.CommandText = "[dbo].[MyStoredProcedure]"
        cmd.CommandType = CommandType.StoredProcedure
        cmd.Parameters.AddWithValue("FileName", DbType.String).Value = "MyFileName"
        cmd.Parameters.AddWithValue("Title", DbType.String).Value = "MyTitle"
        cmd.Parameters.AddWithValue("ReturnID", DbType.Int32).Direction = ParameterDirection.Output
        Dts.Connections("MyConnection").ReleaseConnection(Nothing)
 End Sub




Thank you,
