rich textbox flickers
I'm trying to highlight certain keywords AS THE USER TYPES text in a rich textbox. The only way I could think of was to search through the whole textbox everytime the CHANGED event is fired, and then colorize the keywords (which turns out to be really slow).
The problem is that it flickers alot, because I'm selecting and unselecting certain keywords in order to colorize them. I tried the suspendlayout method, but sounds like it doesnt do anything whatsoever

aah I used the LockWindow API, and it doesnt flicker anymore. But it's extreemly slow. If you start typing a little fast, it wont update the textbox as you type  what should I do

Maybe you could thread the highlight code so it doesn't hang the rest of the app.

Another way is to only colorize on enters and spaces because thats really when you want to check words to be colored. Add that to the threading method and you should be ok.

Maybe in the TextChanged event you could keep a static variable of the last Text.Length then if it increases by more than 1 they probably pasted something in instead of typed it in.
