Hi,

I am tasked with writing a COM+ application in C# in which the program,
when started, will sit and poll for something (not important here), and
when that condition occurs, then I publish events so that subscribing
applications can do something. I've written a basic shell of a program
that I can install as a COM+ application (w/ gacutil, regsvcs, etc),
but my question is, since a COM+ application has no user interface, or
wait state like a Windows program with a timer, how do I make a COM+
application just sit there and do something at a partuicular interval?
I see there is the System.Threading.Timer class that I could possibly
use, but where would I instantiate it in the class? Are there any
startup methods that I can override?

All the COM+ examples I've seen have the COM+ methods invoked by a
client process only.

Any ideas?

TIA,
Robbie

One possible solution would be:

A windows service that uses (hosts) a COM+ component and other applications
use loosely coupled events ( LCE) to recieve notifications as required.
The COM+ component could be either a library or server component.
