Sorry for all the questions!

1) How can i open a html file into a rich text box or normal text box? Is it the same as opening a text file? I want the code to show?

2) How can i then only show a specific bit/s of the code. So basically someone with no knowledge of web programming can come in and add text it etc.

3) Then save the file as filename.html overwriting the old one!!

Thanks for any help!
