Create A Html But Not With VB?

I have a few questions about HTML editor. I never had to use it in visual basic, now I do know how to create a html. But not with visual basic. Now I do know how to make the box to have the files new open save exit. But I watch a video on how to create a HTML Editor. But I am kinda confused. My project is allow the user to create a new HTML. Open an existing HTML file from your hard drive(which I don't understand that one). Save an HTML file. Use a menu with the following items File, New, Open, Save, Exit.(I already know how to do this) But in the video the used a Krypton Tab.
