This thread is for discussions of .NET Threading Part II.

hi, interesting article you've written here. just one question, and that is do you know of a function in .NET/C# equivalent to the old PostThreadMessage. The intention here is not to pass any information to a spawned thread via the LPARAM parameter, but rather just to inform the thread of the fact that some information is ready for them to collect (available at a singleton object which is made thread-safe). I tried using the approach of firing events and having the event handled by a delegate but only managed to make this work in the context of the same thread, not across threads. Any ideas?

Thanks

Alastair.

Greetings-
I have been doing alot of reading in this area and am frankly confused on which model/classes to use for a specific implementation I am working on. Perhaps you could shed some light.

I have a large treeview on a UI thread, with nodes that contain collections of images that take a long time to render previews for in a panel. I would like to let a worker thread render the set of previews based on the treeview node selected, passing each preview back to the ui thread as they complete. Of course, it's bad form to have a worker thread access objects in the UI thread.

I have tried async delegate calls and got it working on the UI thread, but it still locks the UI while it's rendering the previews. I am confused about wether to use events, a ThreadPool, Mutex stuff, or what?

Can you help me out here?

Many Thanks
