Working Around the 255-Character Limitation of the NoteText Method
Although the NoteText method of a cell is limited to a maximum of 255
characters, you can insert a comment that is up to 32,767 characters in
length in a cell. To do this, use the Text method of a Comment object that
is attached to the cell. For example, instead of the following code
ActiveCell.NoteText "This is a 1000 character comment."
use a line of code that is similar to the following:
ActiveCell.Comment.Text "This is a 1000 character comment."
Using the NoteText Method with Comments Longer Than 255 Characters
If you use the NoteText method to insert a comment that is longer than 255
characters in length in a cell, the new comment is not inserted in the
cell, and you do not receive an error message.
For example, if you run a macro with the following code
ActiveCell.NoteText String(256, "x")
and the active cell does not already contain a comment, no comment is added
to the cell because the length of the new comment would exceed 255
characters.
If you run a macro with the following code
ActiveCell.NoteText ActiveCell.NoteText & String(100, "x")
and the length of the existing comment exceeds 155 characters, the comment
is not updated because the length of the new comment would exceed 255
characters.
NOTE: In earlier versions of Microsoft Excel, the first 255 characters of
text are applied to the comment; the remaining characters are truncated.
Using Comment.Text to Change the Comment in a Cell
When you use Comment.Text to change the comment in a cell, the cell must
already contain a comment. If no comment was previously inserted in the
cell, you receive the following error message:
Run-time error '91':
Object variable or With block variable not set
To insert a comment in a cell, use code similar to the following:
ActiveCell.AddComment
NOTE: If the active cell already contains a comment, you receive the
following error message when you run the code:
Run-time error '1004':
Application-defined or object-defined error
To add a comment to a cell that may or may not contain a comment, use code
similar to the following:
Sub AddACommentToTheActiveCell()
' The following line suppresses the run-time error message when
' adding a comment to a cell.
On Error Resume Next
' Add a comment to the cell. If the cell already contains a comment,
' this line does nothing.
ActiveCell.AddComment
' Return to normal error handling.
On Error GoTo 0
' Add the text to the comment. If the cell already contains a
' comment, this is all you actually need.
ActiveCell.Comment.Text "This is a comment."
End Sub
Using Comment.Text to Add New Text to an Existing Comment
If you want to add new text to an existing comment while preserving the
original comment text, use a line of code similar to the following:
ActiveCell.Comment.Text ActiveCell.Comment.Text & "New Comment Text"
Characters over the 32,767-character limit for comments are truncated.
