I use arrays to fill ranges with values all the time because is it is so fast.

targetRange = myarray

Is there any equivalent (or alternative method) for adding a large number of
comments without having to loop through every location in the target range.

It would be nice if the following worked but it doesn't

targetRange.text = myarray

Andrew

hi,
yes. see this site.
http://www.contextures.com/xlcomments03.html#Name
you may have to scrool. I haven't been in Debra's site in a while but she's
good on comments.
I would guess that you should be able to loop through the range, adding a
plain comments but you may have to use inputbox to type in the comment.

Good luck

Hi Andrew -

Although the AddComment method does add text to a cell's comment, my testing
demonstrated to me that each cell must be assigned a comment explicitly; the
'array-to-range' batch assignment (that you described) that works so well for
cell contents does not appear to work with the AddComment method.

So, the code below assigns comments cell-by-cell. It also senses the
'shape' of the selected target range. You will have to do two things to make
sure it works for you.

First, insert code to fill your own array as desired at the beginning of the
procedure.

Second, you'll have to verify that the comments are hitting the cells as you
intend. Because there is no way to know how you are loading your array (row
by column or column by row), you must test the code and, if necessary, either
invert your array elements or change the indices of the for...next loops in
the code below.

Good luck and let us know if it needs modification...

Wow Jay, you did a lot of work there, thanks - the question was basically
conceptual, as you answered in the first few lines. If I do come across a
faster way to do this I will report back but it looks like element by element
it has to be.

Cheers

Andrew
