Activator.GetObject Method (Type, String)

[newscorrespondent]

This method does not fail if the site is not running! Is there a way to
check the proxy for failure?
Thanks

Tom,

What do you mean if the site is not running? Can you post an example?

Hi Tom,

Are you talking about remoting? Can you provide a code sample?

Google first, ask later.

Yes

// start the process to talk to
Process TrackersProcess = Process.Start(@"some good thing to starg",
TrackerBuilder.ToString());

// set me up to send
ClientChannel = new IpcClientChannel();
ChannelServices.RegisterChannel(ClientChannel, true);
WellKnownClientTypeEntry remoteType = new
WellKnownClientTypeEntry(typeof(MTGClassLibrary.MT GTracksMessage),
TrackerURL);
RemotingConfiguration.RegisterWellKnownClientType( remoteType);

// here is the example

MessageTracker = (MTGTracksMessage) Activator.GetObject
(typeof(MTGClassLibrary.MTGTracksMessage), TrackerURL);

If I comment out the start process the GetObject still works.

This is by design. Activator.GetObject
does not actually connect, it only returns proxy object. Connection is
established at the moment first remote call is made ("lazy connect").
That was bad desing decision IMHO, but it is as it is. You could
implement dummy method ("Ping()") on your remote object on which you can
check (and force) connection.

That was the way I read it but I often miss the obvious.

Thanks
