There is a product called Text Control that you could buy that has everything you need for richtext. I actually developed my own richtext toolbar control. It executes B I U, L C R (justify), bullets, increase decrease indent, highlight, change font type, size, and color. It only needs 3 lines of code inserted into a form. The coding part is not too difficult, but I had to get a friend to help me on the graphics for each button. I'm not too good at graphics. If you have the time build your own, if you have the money buy one. If you build it and need help, just post a question. Here is the text control site. Good luck.
