Examples

This example puts a time stamp on each InkWordNode in an InkAnalyzer, theInkAnalyzer. It adds a property with a Guid, timeStampGuid, first checking to see if the node already contains a time stamp.

Dim inkWords As ContextNodeCollection = _
    theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord)
Dim inkWord As ContextNode
For Each inkWord In inkWords
    If Not inkWord.ContainsPropertyData(Me.timeStampGuid) Then
        inkWord.AddPropertyData(timeStampGuid, DateTime.Now)
    End If 
Next inkWord

            ContextNodeCollection inkWords =
                theInkAnalyzer.FindNodesOfType(Microsoft.Ink.ContextNodeType.InkWord);
            foreach (ContextNode inkWord in inkWords)
            {
                if (!inkWord.ContainsPropertyData(this.timeStampGuid))
                {
                    inkWord.AddPropertyData(timeStampGuid, DateTime.Now);
                }
            }
