Esempio

Private Function CurrentSelection(ByVal target As AutomationElement) As TextPatternRange

Commenti

Se non viene selezionato alcun testo, GetSelection restituisce l'intervallo di testo degenerato (intervallo vuoto) nella posizione del cursore di sistema (punto di inserimento del testo).

Se il cursore di sistema (punto di inserimento del testo) non è presente, GetSelection potrebbe restituire null.
