I got two combo boxes, one has numbers from 1-75 and the other one has all system fonts. I have a richtextbox as well. I basically want the user to be able to choose the font and font size from the combo box and then apply to the richtextbox. However I want about two functions. If the user has highlighted selected text then changes should only be applied to the highlighted text, if the user has not highlighted an item but changes fonts or font size, then the changes should be made to the next characters inputed.
How can I do this?
