dotnet remoting : Using GUI from .NET Remoting events

You are confusing a number of things here.
1. Remoting as nothing to do with COM and Apartments (COM context
boundaries).
2.MTA and STA's have nothing to do with Control.Invoke. Control.Invoke is a
must when you need to touch the UI from another thread than the UI thread.

Simply in your case you have a UI thread that runs in an STA, that's needed
for COM interop with COM based UI elements. When you have another thread
(MTA/STA no matter what) that sinks remoting events, and you need to update
the UI from that thread, you have to marshal the call using Invoke or
BeginInvoke, point.

I have a server with .NET Remoting object, which has significant
number of events. I want to use these events from my client GUI
application. When an event is passed to the client application, it is
running under MTA (Multithread Apartment) and I have to use
Control.Invoke() to marshal it to STA (Singlethread Apartment).

Is there an other way to do this? Can I customize the .NET Remoting to
ensure that events are run under STA?

Thank you very much,

I am very sorry; I tried to make the post short and I over-simplified
it. Plus, this is my first post to newsgroups.

Ok, the call must be marshaled using Invoke. My question is: Do I have
to call the Invoke in every event handler that accesses UI or can I
move the call to .NET Remoting by tweaking something?
