MSWord - readonly and protected, what's the difference?

I'm trying to get a line of code right, but am having trouble understanding the difference between these two things.

Basically, I want to say, "if the document is readonly, remove the readonly property".

VB Code:

If ActiveDocument.ReadOnly = True Then
        ActiveDocument.Unprotect
    End If

This doesn't work as apparently the file is readonly but not protected.
Readonly is an unassignable property, so it's not possible to declare
ActiveDocument.Readonly = False

Protected means that Word has been set to protect the contents of the file. Read only is a file level setting (right-click select Properties) and can't be unset from within Word. It will need to be unmarked from outside Word somehow.

So if a file was protected I couldn't for example edit some of the text and save as a new document?
Thanks for clearing that up :)

Correct.... I think that's the way it works.

With Read-Only you can change the content, but then you have to do a File -> Save As... with it.
