It's also mentioned in passing in "Reference-Volume 1" of SDK 3.0.

Thanks! That's basically what I wanted to do.

Well, now I have another question. I'd like to make some text lines in the edit
control a different color.  I guess I'd have to intercept several messages
to get this to work, like WM_PASTE, WM_PAINT, WM_CHAR, probably some others
too, but since Win3.0 does the actual drawing of the characters on the screen,
how can I change their color?  Could I do something like was suggested above,
only in some cases not call the windows edit control proc? Is this a kosher
thing to do?
