Gets or sets a name of the comment author.
Comments are identified by their authors, so it is possible to determine who entered each comment in a shared workbook. For example, in Microsoft® Excel® the author of a comment appears in the status bar when the mouse hovers over a commented cell.
This example demonstrates how to add a comment to a cell and format the comment text.
To create a new comment and associate it with a cell, access the worksheet’s collection of cell comments from the Worksheet.Comments property and call the CommentCollection.Add method. Pass the following parameters:
To apply different fonts to specific regions of the comment text, modify the CommentRunCollection collection, which is accessed from the Comment.Runs property. This collection stores the CommentRun objects (comment runs) that define regions of the comment text that are formatted specifically. After a comment has been created, its text is defined by a single run that is contained in the CommentRunCollection collection.
Add more runs to the comment.
- Insert the author’s name at the beginning of the comment text (using the CommentRunCollection.Insert method) and format it as bold.
- Access the comment text that was added initially. It is now defined by the second run in the collection of the comment runs. Modify font characteristics for this text region.
- Add one more run to the end of the comment text using the CommentRunCollection.Add method.
As you can see, cell comments can be formatted using methods of the CommentRunCollection object.
