Call A DLL Or EXE File From SQL Trigger

I need some help calling a DLL or EXE from a SQL Trigger.  I have the trigger set up, except I have no clue how to call a DLL or EXE or if it is even possible.  Here is what I have for the Trigger so far: 






-- ================================================
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
-- =============================================
CREATE TRIGGER CallProgIfParentID
ON Toc
FOR INSERT
AS
IF ((select ins.[ParentID] FROM inserted ins) = '57660')
-- I want to be able to programmatically change '57660' from an ASPX page
EXEC
-- This is where the call function goes
GO







Another question I have is can a trigger be created programmatically using ASPX pages written in VB.NET in VS2003?

Thank you in advance
