Thanks for your reply Igor
The idl has:
import "oaidl.idl";
import "ocidl.idl";
  helpstring("IBeepObj Interface"),
 interface IBeepObj : IDispatch
  [id(1), helpstring("method Beep")] HRESULT Beep([in] long lDuration);

 helpstring("BeepServer 1.0 Type Library")

  helpstring("BeepObj Class")
 coclass BeepObj
  [default] interface IBeepObj;

From that I have
3 IDs and I thought you only get 2 (CLSID and IID). Which is which?

Assuming the last ID is the CLSID is it simply:
const CLSID CLSID_BeepObj =

Thanks for your help.

I am doing a tutorial on COM. I have created a server object
(beepServer) with ATL. I want to call that object from a client. My
question is where do I get the CLSID and the IID from?

Look at the IDL file in your server project, and the .h file generated
from it.

I think that when it compiled on my machine it would have generated a
different CLSID to what the author's had, but the format is completely

It's just a different way to write the same bits.

necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
