Is there a way to get an ASYNC MessageBox?

Question

Or do I need to use threads? (C ++)

Answer 1

No no. In addition, you can create a "modeless dialog box."

Answer 2

Message boxes are modal dialogs. The whole idea is that they are not asynchronous. Assuming this can be done (which is exactly, given the right amount of messing around), do you want to confuse users with something that looks familiar, but acts differently than they expect? The question is why do you want to do this? there may be a better solution.
