Aspose::Words::Comment::Comment constructor

Comment::Comment(const System::SharedPtr<Aspose::Words::DocumentBase>&) constructor

Initializes a new instance of the Comment class.

Aspose::Words::Comment::Comment(const System::SharedPtr<Aspose::Words::DocumentBase> &doc)

Parameter	Type	Description
doc	const System::SharedPtr<Aspose::Words::DocumentBase>&	The owner document.

Remarks

When Comment is created, it belongs to the specified document, but is not yet part of the document and ParentNode is null.

To append Comment to the document use InsertAfter() or InsertBefore() on the paragraph where you want the comment inserted.

After creating a comment, don’t forget to set its Author, Initial and DateTime properties.

Examples

Shows how print the contents of all comments and their comment ranges using a document visitor.
