script component as datasource with stored prcedure

I am trying to use the script component as a datatask source

The stored procedure takes a varchar(250) parameter

I have created the output columns and got so far in the script but am now stuck

can anyone guide me

Public Class ScriptMain
    Inherits UserComponent
    Dim connMgr As IDTSConnectionManager100
    Dim sqlConn As SqlConnection
    Dim sqlCmd As SqlCommand
    Dim sqlParam As SqlParameter
    'This method is called once, before rows begin to be processed in the data flow.
    '
    'You can remove this method if you don't need to do anything here.
    Public Overrides Sub AcquireConnections(ByVal Transaction As Object)
        connMgr = Me.Connections.MYConnection
        sqlConn = CType(connMgr.AcquireConnection(Nothing), SqlConnection)
    End Sub
    Public Overrides Sub PreExecute()
        MyBase.PreExecute()
        sqlCmd = New SqlCommand("EXECUTE sp_CRM_ImportARUDD", sqlConn)
        sqlCmd.CommandType = CommandType.StoredProcedure
        sqlParam = New SqlParameter("@FileName", SqlDbType.NVarChar, 250)
        sqlParam.Direction = ParameterDirection.Input
        sqlCmd.Parameters.Add(sqlParam)
    End Sub
    Public Overrides Sub PostExecute()
        MyBase.PostExecute()
        '
        ' Add your code here
        '
    End Sub
    Public Overrides Sub CreateNewOutputRows()
        '
        ' Add rows by calling the AddRow method on the member variable named "<Output Name>Buffer".
        ' For example, call MyOutputBuffer.AddRow() if your output was named "MyOutput".
        '
    End Sub
End Class
