Article

Retrieves a globally unique identifier (GUID) that specifies the confidence level of the RecognitionAlternate object.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)

Syntax

'Declaration
Public Shared ReadOnly ConfidenceLevel As Guid
'Usage
Dim value As Guid 

value = RecognitionProperty.ConfidenceLevel

Field Value

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

Remarks

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.

Examples

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

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