I have a problem with Fire_Event that I can't figure out, and some help
would be appreciated. The "problem" is probably from my lack of
understanding of COM.
I have a server with three interfaces, one outbound event interface, and two
inbound interfaces
import "oaidl.idl";
import "ocidl.idl";
[ object, oleautomation, uuid(...),helpstring("The event
interface") ]
interface IServerEvents : IUnknown {
[id(10)]
HRESULT RunState([in] BSTR app, [in] long state);
[object, oleautomation,uuid(...),helpstring("First inbound interface") ]
interface Itest1 : IDispatch {
[id(10), helpstring("Connect the system")]
HRESULT connect([in] BSTR system);
}
[ object,oleautomation,uuid(...),helpstring("second interface")]
interface Itest2 : IUnknown {
[id(30)]
HRESULT register([in] BSTR appname);
};
/*------------ The library interface -------------*/
[
uuid(...),
version(1.0),
helpstring("Test interfaceType library")
]
library interfaceLib
{
importlib("stdole2.tlb");
/*typedef enum deleted, not relevant here*/
[
uuid(...),
helpstring("nterface class object")
]
coclass testInterface {
[default] interface ITest1;
[default, source] interface IServerEvents;
interface Itest2;
};
};
----
The problem is that events fired from Itest2 methods (i.e using a Fire_Event
within the register method) is never propagated and never reaches clients
that are listening with ShowEvents, while events fired from Itest1 is. The
server is running as a local server, STA.
I have tried the following combinations on the server side:
self.Fire_Event(0, 'RunState', 'test', 3)
self.Fire_Event(...IServerEvents, 'RunState', 'test', 3)
Watching the debug output, I can see that the
.connectionpoints._call_sinks(...) is always executed when I call
Fire_Event(), but the object addresses of the ConnectionPointImpl object are
different depending on where the Fire_Event originates (from Itest1 or
Itest2)
