        ' of all emails having the word Viagra in the subject
        Dim msgSet As Chilkat.MessageSet
        msgSet = imap.Search("SUBJECT Viagra", 1)

        ' Loop over the message IDs and copy each message to another folder and
        ' delete it from the Inbox.  A MOVE operation in IMAP is done by copy
        ' and delete.

        For i = 0 To msgSet.Count - 1
            ListBox1.Items.Add("Moving message ID " & msgSet.GetId(i))
