Exemples

L'exemple suivant montre comment parcourir en boucle un ContextNodeCollection à partir du InkAnalyzer. FindNodesOfType(ContextNodeType, ContextNode) d'un InkAnalyzer, theInkAnalyzer. L'exemple parcourt en boucle tous les nœuds de ligne et les marque en rouge si deux nœuds de mot manuscrit sont présents et contiennent le même mot.

' 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(Microsoft.Ink.ContextNodeType.Line)
Dim lineNode As ContextNode
Dim stroke As Stroke

For Each lineNode In lines

    Dim previousWord As InkWordNode = Nothing
    Dim inkWord As InkWordNode
    For Each inkWord In _
        theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord, lineNode)

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

            For Each stroke In previousWord.Strokes
                stroke.DrawingAttributes = New DrawingAttributes(Color.Red)
            Next stroke
            For Each stroke In inkWord.Strokes
                stroke.DrawingAttributes = New DrawingAttributes(Color.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 =
