Client side Remoting Question

In my server app I perform the following:

//-------------------------------------------
remoteObject remoteObj = new remoteObject();
ChannelServices.RegisterChannel(new TcpChannel(tcpPort));
ObjRef refSubManager = RemotingServices.Marshal(remoteObj, "remoteObject");

In the Client app I attempt to do this:
//--------------------------------------------
TcpChannel chan = new TcpChannel();
ChannelServices.RegisterChannel(chan);
object obj = (remoteObject) Activator.GetObject(typeof(remoteObject),
"tcp://" + serverIP + ":" + tcpPort + "/remoteObject");

remoteObjectLocal = obj as remoteObject;

if (remoteObjectLocal == null)
{
MessageBox.Show("Server is not running");
}
else
{
MessageBox.Show("Server is running");
}


Trouble is since remoteObjectLocal is a proxy it NEVER returns null (even if
the server is not running). How do I tell from the client side that the
server is serving up the remot object? I can get the proxy when the server
is running, I just need to verify the server is running before attempting to
use the proxied object.

Thanks,

Matt

Hi Matt.

Try calling the obj.ToString() It'll throw an exception, if the object
isn't available (ie. the server is not running).
