Hiding headings/gridlines on opening of document

I did some searching around in the past postings for an answer to this, but with no luck.

Is there a way to hide the column headings/row headings and gridlines automatically when a workbook is opened without having the user go to the view tab and unchecking the appropriate boxes?

I found the code to hide the formula bar, but couldn't find anything on this.

Thanks for any help or answers regarding this.
