I've made a HTML-Editor in VB using the RichTextEditBox.

Now I want to colour the tags etc..
E.g. tag and name in blue, tagsubtypes in red and stringvalues in green (it's only an example!).

How to do that running very fastly?
Normaly it's too slow (on big files... take a nap...).


Does someone know how'to manage that?

Thanks!
