Esempi

Nell'esempio seguente viene illustrato come riprodurre a ciclo continuo tutti gli oggetti LineNode di un oggetto InkAnalyzer denominato theInkAnalyzer. Per ogni riga, vengono riprodotti a ciclo continuo tutti gli oggetti InkWordNode e se vengono riconosciuti due oggetti consecutivi InkWordNode con la stessa parola, questi vengono contrassegnati in rosso.

' If two identical ink words occur next to each other, mark them as red.
' Note: This doesn't actually look for pairs that go across two lines.
Dim lines As ContextNodeCollection = theInkAnalyzer.FindNodesOfType(ContextNodeType.Line)
Dim lineNode As ContextNode
For Each lineNode In  lines
    Dim previousWord As InkWordNode = Nothing

    For Each inkWord As InkWordNode In _
        theInkAnalyzer.FindNodesOfType(ContextNodeType.InkWord, lineNode)

        If Not (previousWord Is Nothing) AndAlso _
            previousWord.GetRecognizedString() = inkWord.GetRecognizedString() Then

            For Each stroke As Stroke In previousWord.Strokes
                stroke.DrawingAttributes.Color = Colors.Red
            Next stroke

            For Each stroke As Stroke In inkWord.Strokes
                stroke.DrawingAttributes.Color = Colors.Red
            Next stroke
        End If

        previousWord = inkWord
    Next inkWord
Next lineNode

// If two identical ink words occur next to each other, mark them as red.
// Note: This doesn't actually look for pairs that go across two lines.
ContextNodeCollection lines =
    theInkAnalyzer.FindNodesOfType(ContextNodeType.Line);
foreach (ContextNode lineNode in lines)
{
    InkWordNode previousWord = null;
    foreach (InkWordNode inkWord in
             theInkAnalyzer.FindNodesOfType(ContextNodeType.InkWord, lineNode))

        if (previousWord != null &&
            previousWord.GetRecognizedString() == inkWord.GetRecognizedString())
        {
