Hi

I want to access a remote object to raise an event. How do I get the
reference to the object from the server application?
I tried to use a singleton but this does not work.

thanks
Dan

Guessing...that you know how remoting works ?

You should use a singleton with a lease timeout set to infinite otherwise ,
it will still create new instances

copy and paste this region in your singleton
#Region " Remoting Override "
''' -----------------------------------------------------------------------------
''' <summary>
''' this method will make sure that the leasetime will be infinite
''' </summary>
''' <returns>Nothing as valid lease point expiration time </returns>
''' <remarks>
''' </remarks>
''' <history>

Public Overrides Function InitializeLifetimeService() As Object
Return Nothing
End Function
#End Region

Hi Michel

As this is my first project with remoting I started with downloading an
example that shows the basic event usage with a chat application. This
example already contains your code region.
Raising the event from within the remote object works fine, but from another
server class is not working

Well in that case it should be pretty simple
you can just create a sub in your interface and thus raise the event from
the sub from anny client atached to the singleton

This works for the client, but from the server I get still another instance
of the remote object, even if the remote object was already used (created) by
the client.
