Best way to connect(notify) to an existing Delphi desktop application that will now be deployed on a server

I have an application that connects to an SQL server, gets articles and associated data then creates HTML files. Now I want to use this app on windows server 2008. I am using an ASP.NET application to write and update articles to the SQL server.
Any ideas on how to notify the Desktop app that a new article has been added or updated on the sql server?
Just setting one flag is enough like updateavailable:=true . How would I communicate the state of this flag to the delphi app. TCP? CGI?
thanks

The simplest way is to create a timer in your delphi application, and query the flag in the database every a few minutes. The limitation is that it may delay a few minutes when an update is commited.

Another solution is using Sql server notication service. You can write a .net client if you are using delphi.net.  Here is a tutorial for writing a c# client.
