Range.DetectLanguage Method

  • Artigo
Word Developer Reference

Analyzes the specified text to determine the language that it is written in.

Syntax

expression.DetectLanguage

expression   Required. A variable that represents a Range object.

Remarks

The results of the DetectLanguage method are stored in the LanguageID property on a character-by-character basis. To read the LanguageID property, you must first specify a selection or range of text.

When applied to a Document object, the DetectLanguage method checks all available text in the document (headers, footers, text boxes, and so forth). If the specified text contains a partial sentence, the selection or range is extended to the end of the sentence.

If the DetectLanguage method has already been applied to the specified text, the LanguageDetected property is set to True. To reevaulate the language of the specified text, you must first set the LanguageDetected property to False.
