Answer 1

You could also use PostMessage to safely queue, or SendMessage to safely synchronize from an anonymous thread.

Answer 2

You can use PostMessage(Form.Handle, WM_UPDATEMYCOMP, 0, 0);

You can define your own message id, wparam, lparam, with a bit of work you can turn them into more complicated parameters.

Answer 3

You can use synchronize in this case, e.g.:

TThread.Synchronize(nil, procedure begin UpdateComponent(); end);

And if you want asynchronous method call execution within the main thread, you can use TThread.Queue, e.g.:

TThread.Queue(nil, procedure begin UpdateComponent(); end);
