D5 - TOLEServer event handling

Hi,

Has any one managed to use multiple instances of a TOLEServer to provide
multiple event handlers to a single in-process automation object.
The first TOLEServer autocreates the server and handles the events...
A second instance (connected with ConnectTo) with a ConnectKind of
ckAttachToInterface can access all the methods from the auto object but
does not receive any events......

Thanks

Phil

Re:D5 - TOLEServer event handling

The ability to support multiple sinks (clients) should be implemented by the
server. In particular, if your server is also written in Delphi, make sure
when the ConnectionPoint is created on the server side, you specify ckMulti
instead of ckSingle. In addition, you'll have to learn how to use
IEnumConnections to trigger events to multiple clients.

have fun

Re:D5 - TOLEServer event handling

In D5, you dont have to use IEnumConnections, you can use the property
SinkList: TList of TConnectionPoint which holds pointers to IUnknowns from
the clients sinks.
