Example

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(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(ContextNodeType.InkWord);
foreach (ContextNode inkWord in inkWords)
{
    if (!inkWord.ContainsPropertyData(this.timeStampGuid))
    {
        inkWord.AddPropertyData(timeStampGuid, DateTime.Now);
    }
}
