Examples

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

' Only highlight if strong recognition 
If customRecognizer.InkRecognitionConfidence = Microsoft.Ink.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. 
    Dim theStroke As Stroke
    For Each theStroke In customRecognizer.Strokes
        theStroke.DrawingAttributes = _
                    New DrawingAttributes(Color.Black)
    Next theStroke
    Dim selectedNode As ContextNode
    For Each selectedNode In selectedNodes
        For Each theStroke In selectedNode.Strokes
            theStroke.DrawingAttributes = _
                     New DrawingAttributes(Color.Red)
        Next theStroke
    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 == Microsoft.Ink.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 =
                    new DrawingAttributes(Color.Black);
    }
    foreach (ContextNode selectedNode in selectedNodes)
    {
        foreach (Stroke stroke in selectedNode.Strokes)
        {
            stroke.DrawingAttributes =
                     new DrawingAttributes(Color.Red);
        }
    }
}
