I have been trying to find a source for the codes i.e. \b \fs etc that are embedded in the richtextbox text. I would like to do some things that aren't documented (at least that I know of) I.E I would like to set the background color within the text as opposed to setting the foreground color with Selcolor. I brought up a blank word document and wrote text involving all the features I wanted saved it in RTF format and then brought up that RTF file in notepad to find out what the codes were. I couldn't figure out the codes.
