Значение поля

Тип: System.Guid
The globally unique identifier (GUID) that specifies the confidence level of the RecognitionAlternate object.

Заметки

The Tablet PCapplication programming interface (API) uses GUIDs to identify packet properties, recognition properties, drawing attributes, and general ink properties. These GUIDs are available as read-only fields of the RecognitionProperty object. Use these GUIDs to access properties of a RecognitionAlternate object by calling the GetPropertyValue method.

ConfidenceLevel specifies the level of confidence that the recognizer has in the recognition result.

Of the Microsoft® recognizers, only the Microsoft English (US) Handwriting Recognizer and the Microsoft Gesture Recognizer support confidence levels. Third party recognizers may or may not support confidence levels.

Примеры

In this example, the first Recognizer that supports German (language ID 1031), the RecognizerCapabilities capability LinedInput, and ConfidenceLevel is assigned to the selected Recognizer object variable.

Dim selectedRecognizer As Recognizer = Nothing
Dim allRecognizers As Recognizers = New Recognizers()
For Each oneReco As Recognizer In allRecognizers
    ' if we haven't found the one we want yet
    If Not selectedRecognizer Is Nothing Then
        ' if supports LinedInput
        If (oneReco.Capabilities And RecognizerCapabilities.LinedInput) <> 0 Then
            For Each langID As Short In oneReco.Languages
                ' if supports German (1031)
                If langID = 1031 Then
                    For Each propertyGuid As Guid In oneReco.SupportedProperties
                        ' if supports ConfidenceLevel
                        If propertyGuid = RecognitionProperty.ConfidenceLevel Then
                            ' assign selected
                            selectedRecognizer = oneReco
                        End If
                    Next
                End If
            Next
        End If
    End If

        if ((oneReco.Capabilities & RecognizerCapabilities.LinedInput) != 0)
        {
            foreach (short langID in oneReco.Languages)
            {
                // if supports German (1031)
                if (langID == 1031)

                        if (propertyGuid == RecognitionProperty.ConfidenceLevel)
                        {
                            // assign selected
                            selectedRecognizer = oneReco;
                        }
                    }
