Example

The following example uses a TextBox, selectedResultsTextBox. Previously, the Text property has been set to the value returned by GetRecognizedString for a CustomRecognizerNode object, customRecognizer. The user has selected some of the text in the TextBox. If the InkRecognitionConfidence level is Strong, the Strokes that correspond to that selection are highlighted in red.

' Find out what's been selected in the text box
Dim start As Integer = selectedResultsTextBox.SelectionStart
Dim length As Integer = selectedResultsTextBox.SelectionLength

' Return if no text is selected.
If length = 0 Then
    Return
End If

' Only highlight if strong recognition
If customRecognizer.InkRecognitionConfidence = _
   InkRecognitionConfidence.Strong Then

    Dim selectedNodes As ContextNodeCollection = _
        customRecognizer.GetNodesFromTextRange(start, length)

    ' Use the new start and length value to update the
    ' selection in the TextBox
    selectedResultsTextBox.SelectionStart = start
    selectedResultsTextBox.SelectionLength = length

    ' Color the strokes red if part of the selected words.
    ' Otherwise, color them black.
    For Each Stroke As Stroke In customRecognizer.Strokes
        Stroke.DrawingAttributes.Color = Colors.Black
    Next Stroke

    For Each selectedNode As ContextNode In selectedNodes
        For Each Stroke As Stroke In selectedNode.Strokes
            Stroke.DrawingAttributes.Color = Colors.Red
        Next Stroke
    Next selectedNode
End If

// Find out what's been selected in the text box
int start = selectedResultsTextBox.SelectionStart;
int length = selectedResultsTextBox.SelectionLength;

// Return if no text is selected.
if (length == 0)
    return;

// Only highlight if strong recognition
if (customRecognizer.InkRecognitionConfidence == InkRecognitionConfidence.Strong)
{
    ContextNodeCollection selectedNodes =
        customRecognizer.GetNodesFromTextRange(ref start, ref length);

    // Use the new start and length value to update the
    // selection in the TextBox
    selectedResultsTextBox.SelectionStart = start;
    selectedResultsTextBox.SelectionLength = length;

    // Color the strokes red if part of the selected words.
    // Otherwise, color them black.
    foreach (Stroke stroke in customRecognizer.Strokes)
    {
        stroke.DrawingAttributes.Color = Colors.Black;
    }
    foreach (ContextNode selectedNode in selectedNodes)
    {
        foreach (Stroke stroke in selectedNode.Strokes)
        {
            stroke.DrawingAttributes.Color = Colors.Red;
        }
    }
}
