private TextPatternRange CurrentSelection(AutomationElement target)

}

Private Function CurrentSelection(ByVal target As AutomationElement) As TextPatternRange

    Dim textpatternPattern As TextPattern = CType(textProvider.GetCurrentPattern(TextPattern.Pattern), TextPattern)

    If (textpatternPattern Is Nothing) Then
        Console.WriteLine("Root element does not contain a descendant that supports TextPattern.")
        Return Nothing
    End If
    Dim currentTextSelection As TextPatternRange() = textpatternPattern.GetSelection()
    Return currentTextSelection(0)
End Function

Comentarios

Si no se selecciona ningún texto, GetSelection devuelve el intervalo de texto degenerado (intervalo vacío) en la posición del cursor del sistema (punto de inserción de texto).

Si el cursor del sistema (punto de inserción de texto) no está presente, GetSelection podría devolver null.
