Keyword Highlighting Issue

[Upinflames]

Hello,
I have been working on a project which requires certain keywords such as added names and other keyword to be changed to a different color when typing in a rich edit. Currently, I am using EM_SETCHARFORMAT, however, this isn't what I presume to be the best solution to this issue. EM_SETCHARFORMAT requires that you set the highlighting and because of that it causes a lot of jumping in the control. I was wondering is there another message I could send that would be better? Or would I have to subclass it, and if that is the case, how would I go about doing something like that?

Thank You.

Just to clarify by better, I mean something that does not require me to select the text I would like to format.

To avoid all the jumping in the control, set the redraw to false, do the formatting, then set redraw to true.

Thank You very much for your reply. I tried what you suggested and it did help. But not exactly what I was looking for, because WM_SETREDRAW adds lag in typing now.

The trick is to just do one line at a time. Write two functions; one for a single line, and one for the whole control (or just the visible window). Handle the EN_CHANGE notification and only format one line unless the change is a carriage return or you have multi-line formating to deal with (like C's /* ... */ ).

I don't have to deal with multiple line keywords. About obtaining the single, I am able to obtain the text, however I would also like to know the offset from the entire text to that line. I am not exactly sure how to do that, I have looked through the MSDN references but haven't found anything of much use. Any help is appreciated.
