Description Aaron J. Peterson 2017-03-02 10:50:44 UTC
Comment objects do not have a Parent property defined.  It should be a Range object of the comment's associated cell.  Without that, it is very difficult to do useful work. For instance iterating over ActiveSheet.Comments becomes useless, as you can't where the comments are or what cell contents each relates to. Same behavior on and

Steps to Reproduce:
1. have a worksheet with one or more comments.  
2. get a comment object - eg: comment = ActiveSheet.Comments(1) 
3. MsgBox typeName(comment.Parent)

Actual Results:  

Expected Results:

Reproducible: Always

User Profile Reset: No

Additional Info:
Further example: ActiveSheet.Comments(1).Parent.Parent.Name should return the name of the current Sheet.  Looks like Range.Parent isn't wired up either.  I must be doing this wrong.  

"Function CommentFrom(r As Range)" is trivial but "Sub ExtractAllCommentsToTheRight()" is impossible.

It's not a bug with a document or my setup.  There simply isn't a Parent property on comment objects, and there should be one.  Are you looking for examples of why this should be?  There are a ton of uses - http://dmcritchie.mvps.org/excel/ccomment.htm has a boatload.  Here's a simple one:

Sub DelComments()
    Dim cm As Comment
    Dim ws As Worksheet
    For Each ws In Worksheets
        For Each cm In ActiveSheet.Comments
            cm.Parent.AddComment Text:="Comment is deleted."
        Next cm
    Next ws
End Sub

(from https://www.mrexcel.com/forum/excel-questions/539902-visual-basic-applications-parent-comment.html)

This fails because cm.Parent, which should be the parent cell Range object, is Nothing.  You'll get this error on that line:

BASIC runtime error.
Object variable not set.

I'll make up a file with that script and a spreadsheet with a comment if you think need it.
