How highlight keywords in rich edit control?

This is a question relating to a program being written in C (Win32SDK) for Win95/NT4. I want to set up a rich edit control so that if the user types one of a number of keywords, the word will change color - much as in a program script. Initial thoughts are that a lot of programming will be involved - a new thread to stream out the text on each change/update, a routine to check for keywords, select them (selection hidden) and use a CHARFORMAT on the selection before restoring caret to where it was. Or is there a simpler way?! I feel it probably needs a thread because if there is a lot of text, it may take a while to check it all. But streaming it out on each change seems over the top; however WM_GETTEXT would only get the first 64kb or so. Any ideas? Thanks!

I strongly suggest you to buy Stingray Software's "Objective Edit". It does what you want, and it is certainly worth the money it costs.

Coding it yourself would likely drive you crazy. There is a lot of work to do for every keystroke typed by the user, worry about the modification of existing words and, last but not least, speed. The VisualStudio IDE doesn't even use a RichEdit control (in the source editor) mostly for performance issues!

Thanks Davide - I checked out Objective Edit, but it's MFC only; my code is in straight C, so I don't think it can be used. Thanks for help though!
