'  Once the mailbox is selected, the NumMessages property

'  You may loop from 1 to NumMessages to
'  fetch each message by sequence number.

    '  Download the email by sequence number.
    mimeStr = imap.FetchSingleAsMime(i,bUid)

    '  ... your application may process each MIME string...

'  An alternative is to download each email in the form of an
'  email object, like this:
Dim email As Chilkat.Email
For i = 1 To n

    '  Download the email by sequence number.
    email = imap.FetchSingle(i,bUid)

    '  ... your application may process the email object...


Next

'  Disconnect from the IMAP server.
imap.Disconnect()
