Draw a "red squiggly line" in CHtmlEditCtrl

Question

I am working on creating spell checking functions in my application, which currently uses MFC CHtmlEditCtrl .

Is there a way to draw one of those “red squiggly lines” that you see under spelling errors in an HTML control, under a word that I discovered as a spelling error?

The only way I can think of is to use actual HTML to apply this style, and then break it down in the email you send. This seems rather confusing, as if the user began to apply underline styles to text that they might interfere with.

Is there a way to do this with a drawing?

Thanks in advance.

Required IHTMLRenderStyle interface. You pass this, after filling in, to the AddSegment method IHighlightRenderingServices . Here's an example in (gasp) VB. I did this in C ++ many years ago, although it worked well.
