@Mike cool, thanks! By the way, if you're using .NET 3.0 I think or later, probably the simplest declaration to perform a command on the UI thread is this:

this.BeginInvoke((MethodInvoker) delegate
                                                     {
                                                         this.buttonLogin.Text = "Logging In...";
                                                         this.buttonLogin.Enabled = false;
                                                     });

Where "this" is your form and the closure contains whatever UI elements you want to change. Somewhat streamlined again since the day I did that sample =:)

From line 277 of Form1.cs
// TODO: No idea why we need ‘new object[] {list}’ and not just ‘list’, after all list is of type object[]
// If anyone could shed some light on the matter, please feel free to do so on my blog.

Thought I’d input as I’ve been looking through your code. The reason you need a new object[] is because the parameter to your method is an object[] and so you really need an array with the array as the first element. Otherwise the compiler is trying to interpret your object array as individual parameters to the method you are trying to invoke.

At least that’s what it looks like to me.

BTW, I’ve held onto this code for a while in order to have easy access to all the methods for asynchronous invocation for UI updating. Thanks!

[...] with multi-threading in my app, you would think I would be good at this by now considering I blogged about it not too long ago acting like I knew what I was talking [...]

Thanks. glad you like them.
Yes I mentioned in code commenting I was experiencing a crash if you close the app whilst a thread is running, however luckily it is not due to the reading code, but rather a windows forms exception. However I imagine terminating your thread cleanly prior to the app closing, as msdn states would fix this issue.

Sorry, your sample works fine, but MSDN’s crashes.

Cool samples! But when you push the buttons to start new thread and close the app it crashes. Such a shame…
