| Here is what I've been wondering how to do. Let's say client application invoke an asyncronous call. Client can do anything it wants while the process is going on. Now I want the remote object to call delegate function when the process is done to notify the process is finished. Is there any good sample to show how to do this? Any help appreciated! |

| Async Delegates, CallBack and UI Thread |
| microsoft.public.dotnet.framework.windowsforms |
| Gentlemen, My question is simple. When my WindowsForm calls an Async Delegate which has a registered CallBack, is the CallBack always executed on the UI Thread? Or, do I need to test to see if it is? In my application (MDI), I have a main form that launches another form. When that child form loads it executes an Async Delegate who's target is a method on a static class (Controller). The CallBack i... |

Failing that, at least I assumed the exception data would somehow be available on the AsyncResu... |
