Call dc.StampAll ("TodayDate", Today) In our testing, we've never found a difference in performance between the first two of the three preceding examples. Using the extended class syntax, doc.DateToday = Today, appears to be just as fast as using doc.ReplaceItemValue ("DateToday", Today). In theory, we should see some performance difference because in one case, we are not explicitly telling Lotus Notes that we will update a field item, so Lotus Notes should spend a bit longer figuring out that DateToday is, in fact, a field. However, practical tests show no difference. The dc.StampAll method is faster if you are updating many documents with a single value as in the preceding example. There were some point releases in which a bug made this method much slower, so if you're not using the latest and greatest, please confirm this is working optimally (either with testing or by checking the fix list). But as of Lotus Notes/Domino 6.5 and 7, this is ...
