Example

The following example shows how to loop through all the LineNode objects in an InkAnalyzer, theInkAnalyzer. In each line, it loops through all InkWordNode objects and, if there are two ink word nodes that are recognized as the same word, it marks them as red.

' 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 = 
    theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.Line);
foreach (ContextNode lineNode in lines)
{
    InkWordNode previousWord = null;
    foreach (InkWordNode inkWord in 
             theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord, lineNode))
    {
        if (previousWord != null &&
            previousWord.GetRecognizedString() == inkWord.GetRecognizedString())
        {
            foreach (Stroke stroke in previousWord.Strokes)
                stroke.DrawingAttributes = new DrawingAttributes(Color.Red);
            foreach (Stroke stroke in inkWord.Strokes)
                stroke.DrawingAttributes = new DrawingAttributes(Color.Red);
        }
        previousWord = inkWord;
