Remy,

thankyou for this reply, I'm finally back to this (got to love managing 
developers... sigh).

The code I have is as follows...

In the console app..

and in the data module at event handler of
> void __fastcall THiddenDataModule::IdUDPServerUDPRead(TObject *Sender,
>       TStream *AData, TIdSocketHandle *ABinding)
> {

When I run the client with the parameters of file.txt 400 and try and 
send packages to it, the event handler never gets called.

The same code in a window application works fine.

My reason for doing this (if it helps) is to try and decide if I should 
be using stand alone procedures started from a service to do some work 
for me, or just threads launched by the service (which is how its being 
done now).

I want to see if I can make a console app handle udp messages, and then 
I'll try launching it from a service.

Hope that all makes sense.

Hope someone can help me out here.

Ta.

Peter.
