How do I programatically create Indy components
Hi experts, I am trying to create a service and creating the indy components (tcpserver, udpserver) from code rather than dropping a component on a form. I'm looking for some code sample that shows how to do this.
Thanks.
Thanks.

The GeExpert tip is indeed a very really useful tip! - Thanks!
I'm getting some odd results though like:
Bindings := <>;
It tried to replace the <> with nil - compiles but does not work (crashes) so I just commented them out and it seems to work.
I also had problems with assigning event handlers since I don't have a form. I was able to fix this with a little trick that I think is fine:
type
TEventHandlers = class // create a dummy class
procedure UDPServerUDPRead(Sender: TObject; AData: TStream; ABinding: TIdSocketHandle);
end;
...
var
EvHandlers : TEventHandlers;
....
IdUDPSever1.OnUDPRead := EvHandlers.UDPServerUDPRea
to the component created with the GeExpert code and it seems to work.
I'll continue to test and report back.
Thanks again for the help.

you don't have a form and you want to use an event handler ?
the way you do it with the dummy class is actually the solution!
why you may ask ... well because how the event handler is defined
a event handler is a method, and a method is a procedure of a object
TNotifyEvent = procedure (Sender: TObject) of object;
the *of object* at the end means it must be defined inside a class.
you will have to create a instance of EvHandlers at runtime too...

Actually you should have the indy component in the event handler dummy class.
