[RESOLVED] formatting rtf text

how can i reformat this rtf (keeping the original formatting), so the resulting formatted text will be (either):

toUpper
toLower
sentence case
proper case
toggle case - toggle upper + lower case

heres the rtf:

Code:

---

{\rtf1\ansi\ansicpg1252\deff0\deflang2057{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}{\f1\fnil\fcharset0 Comic Sans MS;}}

{\colortbl ;\red255\green0\blue0;\red0\green0\blue255;}

\viewkind4\uc1\pard\qj\f0\fs17 here's a few \b sen\cf1 ten\cf0 ces\b0  of text to test the \b\i capabilities \b0\i0 of my new code. \cf2 hopefully\cf0  the enhancements \f1\fs30 i've made will work\f0\fs17  as intended. this first test is a test of the textalign\b\i  \ul\b0\i0 justify\ulnone  feature, which (after testing) works as intended.\par

}

Do you insist on the low level? Wouldn't formatting with RichTextBox be easier?

i'd prefer it to be low level because its faster that way. you're probably right but if anyone has any other ideas i'd appreciate hearing them

Well, the truth is out there:

Besides, I'm not sure it'll be faster. You will be working with strings and this is slow (depending on the way you'd implement it though, but it'll be difficult to match richtextbox's speed);

it would've been faster because i had a selectionchanged handler for the rtb + the only way to keep the formatting when working with the selectedtext is to select + change 1 character at a time, before moving on to the next character, which made it really slow. but i put an ignoreselectionchanged property in there + it's fast enough now. thanks for the advice.

edit: initially i parsed the rtf but it's too complicated to do a thorough job
