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);
}
}
