Please see my comment to the question. However, on second though, one pretty general low-cost solution for you could be hosting a WebBrowser control in your MFC application:

Of course, not in edit control, which is designed to show plain text.
And if you meant to show some plain text based on some HTML data, the question would make no sense, because there is no difference for a edit control what text to show. If you meant something else, you should explain it properly.
