Ejemplos

En el ejemplo siguiente, se muestra cómo recorrer en bucle un objeto ContextNodeBaseCollection desde el método InkAnalyzerBase. FindNodesOfType de un objeto InkAnalyzerBase denominado theInkAnalyzerBase. En el ejemplo se recorren en bucle todos los nodos de línea y, si hay dos nodos de palabras de entradas manuscritas en la misma palabra, los marca en rojo.

' 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 ContextNodeBaseCollection = _
    theInkAnalyzerBase.FindNodesOfType(System.Windows.Ink.AnalysisCore.ContextNodeTypeBase.Line)

For Each lineNode As ContextNodeBase In lines

    Dim previousWord As ContextNodeBase = Nothing
    Dim previousWordRecognizedString As String = ""

    For Each inkWord As ContextNodeBase In _
        theInkAnalyzerBase.FindNodesOfType(ContextNodeTypeBase.InkWord, lineNode)

        End If

        ' TODO: I think I can get rid of this and just assign the previous string 
        ' to the current string
