.net remoting

[Peter Schmitz]

Hi,

I just started to write a .net remoting application, but unfortunately,
there are some things I just don't understand/need to ask:

- When I try to register my (tcp) channel on a port that is already in use,
an exception is thrown...how can I react best on this (though rare)
circumstances? What would you suggest?

- When I use the following code, an exception is thrown:

Server:
Dim channel As New TcpServerChanne l("MyTest", 3445)
ChannelServices .RegisterChanne l(channel, True)
RemotingConfigu ration.Register WellKnownServic eType(GetType(M yRemoteClass),
"MyTest", WellKnownObject Mode.SingleCall )

Client:
Dim channel As New TcpClientChanne l
ChannelServices .RegisterChanne l(channel, True)

RemotingConfigu ration.Register WellKnownClient Type(GetType(Wi ndowsApplicatio n1.MyRemoteClas s), "tcp://localhost:3445/MyTest")
Dim x As New WindowsApplicat ion1.MyRemoteCl ass
MsgBox(x.GetLoc ation())
remote class:
Public Class MyRemoteClass
Inherits MarshalByRefObj ect
Public Function GetLocation() As String
Return My.Application. Info.AssemblyNa me
End Function
End Class

The exception that is thrown is the following:
The Undo operation encountered a context that is different from what was
applied in the corresponding Set operation. The possible cause is that a
context was Set on the thread and not reverted(undone ).

Any idea what this means?

Best wishes and thanks a lot,

Peter
