Assembly: Microsoft.Office.Interop.Word (in microsoft.office.interop.word.dll)
There is no ProofreadingError object; instead, each item in the ProofreadingErrors collection is a Range object that represents one spelling or grammatical error.
Use the SpellingErrors or GrammaticalErrors property of a Document or Range object to return the ProofreadingErrors collection.
Use SpellingErrors(index), where index is the index number, to return a single spelling error (represented by a Range object).
Use GrammarErrors(index), where index is the index number, to return a single grammatical error (represented by a Range object).
The Count property for this collection in a document returns the number of items in the main story only. To count items in other stories use the collection with the Range object. If all the words in the document or range are spelled correctly and are grammatically correct, the Count property for the ProofreadingErrors object returns 0 (zero) and the SpellingChecked and GrammarChecked properties of the Document or Range object return True.
