URLDownloadToFile API, how can it be used asynchronously?

Question

How can this API URLDownloadToFilebe used asynchronously? I need to show the download progress through SendMessage to the client window, which is impossible to do because the API seems synchronous and never sends OnProgress until the download is complete. I also saw some example codes with an interface IMoniker, but I can’t find an example that includes reading data asynchronously and saving it to a file. Thanks in advance.
