I tried it in many ways...
The message was"access violation..."
I think the proplem is in clients side.
Something is wrong with the declaration.
In delphi that works perfectly is:

type
  TCallBack = class(TAutoIntfObject, IEbClient)
  procedure CallBackClient(ActionID,UpdateKind: Integer; aValue:
oleVariant); Safecall;
  end;

but in c++ builder I tried in many ways..such as..
class TCallback : IEbClient
{....};

or

class IEbClient  : IDispatch
{.....}

I don't know how to declare "TCallBack = class(TAutoIntfObject, IEbClient)"
(two classes..)

thanks
