Hi Jiri,
is it possible to somehow implement an IDisposable pattern for
FbRemoteEvent? There are a lot of small problems now. For instance:
if i pass an connection object to the FbRemoteEvent constructor there are as
far as i understand two possibilities
1) i as owner responsible for destroying this connection object - doesn't
work for now, if i dispose connection, there is a socket exception, cause
RemoteEvent still tries to read from already disposed stream
2) FbRemoteEvent should destroy it - i didn't find any place in code, where
FbRemoteEvent would manage connection dispose. As i understand, you cannot
stop it from listening at all. the thread, that is reading responses from
server is declared "background" and reads until owning window is destroyed
(and causes bunch of ThreadAbortedException's)
to understand the problem, consider this test case
FbConnection conn1 = new FbConnection("");
conn1.Open();
revent = new FbRemoteEvent(conn1, new[] { "event" });
revent.RemoteEventCounts += revent_RemoteEventCounts;
revent.QueueEvents();
revent.CancelEvents();
revent.RemoteEventCounts -= revent_RemoteEventCounts;
revent.Connection = null;
//this will cause an socket exception
conn1.Dispose();
Is there any possibility to implement some Stop method (that causes stoppage
of all socket/thread stuff) - in my opinion - CancelEvents might do this
work. And it would be nice to know, that the same functionality (and also
dispose of connection) would be done in Dispose method. We can still dispose
connection on our own, but only if we can stop socket listening (and this
must be clearly stated in docu).
