Integration Services :: SSIS Read First Row Column From A Flat File Into Variable

Public Class ScriptMain
Inherits UserComponent
Dim smpid As String
Dim Prdt As String
Dim rcnt As Int64

[code]...

Using the Vb script above I am expecting to read the first row from a flat file source and transferring the data into two variable using script component.

SQL server 2008.
Script task Custom Properties:
Script Task Input Columns:

I get the following errors one after the other:"The collection of variables locked for read and write access is not available outside of PostExecute." "Object reference not set to an instance of an object."
