DateTime now = DateTime.Now;

if (thisStroke.ContainsPropertyData(dtGuid))
{
    // Check whether the existing property matches the current date/timestamp
    DateTime oldDT = (DateTime)thisStroke.GetPropertyData(dtGuid);

    if (oldDT != now)
    {
        // Update the current date and time
        thisStroke.AddPropertyData(dtGuid, now);
    }
}

' Create a guid for the date/timestamp.
Dim dtGuid As New Guid("03457307-3475-3450-3035-640435034540")

Dim now As DateTime = DateTime.Now

' Check whether the property is already saved
If thisStroke.ContainsPropertyData(dtGuid) Then
