The final product is professional in appearence and functionality, complete with font editing, drop down list boxes and a splash screen to display a company logo. To see how this editor is created in 6 steps, go to http://msdn.microsoft.com/library/default.asp?url=/workshop/author/editing/tutorials/html_editor.asp
