This makes a little more light (to me) on the subject. Is this
"dispinterface ICoBpTiEvents { ... }" a C++ syntax?
"OLE View" is an application supplied with Visual Studio 6 which displays type
library information, I guess it might correspond to how the interface is
described in IDL.
This extension will allow to use any interface, f.e., you can use:
__AXREGISTERHANDLER( pDisp, bHandler,
"{F41DF7FB-5014-4859-B4DD-854A9D2143CC}" )
to connect to "Events interface for CoBpTi Object".
Yes, I see. That sounds suitable to me.
I do not like a solution that uses enumeration and returns first
interface, without any knowledge about what kind of interface it is. We
will GPF, if we receive interface not identical to IDispatch. But... OLE
has surprises, so, it could be also a common practice... So, decision is
for those who use it and knows how it works in practice.
Doesn't this code change below that Przemyslaw proposes take care of your
concern?
if( HB_VTBL( pCP )->GetConnectionInterface( HB_THIS_( pCP ) &rriid )
== S_OK )
{
if( IsEqualIID( HB_ID_REF( rriid ), HB_ID_REF( IID_IDispatch ) ) )
break;
}
I must go and make supper!
