Re: Getting Events, for Windows Service

Typefilter was solving the problem on my local machine. But now if somebody
else tries to run my client app he gets an timeout error. This has nothing
to do with eventhandling but as I fear with my architecture.

The server application has a public object called logger, which is
instantiated during construction of the app (I use the standard
constructor). When I try to access one of its members using app.Logger.Name
or I try to register my event I get a "System.Net.Sockets.SocketException"
saying, that connection to the server failed, because the host is not
responding.

When I give my app a member app.LoggerName and let him do this work, it
works. So it seems that the logger is properly instantiated and works.

Do you have any suggestions?

Thanks - Patrick
