Dim success As Boolean = False

Dim imap As ChilkatImap
imap.Initialize("imap")

'  This example requires the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

'  Connect to an IMAP server.
'  Use TLS
imap.Ssl = True
imap.Port = 993
success = imap.Connect("imap.example.com")
If success = False Then
    Log(imap.LastErrorText)
    Return
End If


'  Login
success = imap.Login("myLogin", "myPassword")
If success = False Then
    Log(imap.LastErrorText)
    Return
End If


'  Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
If success = False Then
    Log(imap.LastErrorText)
    Return
End If


'  Once the mailbox is selected, the NumMessages property
'  will contain the number of messages in the mailbox.
'  You may loop from 1 to NumMessages to
'  fetch each message by sequence number.

Dim bUid As Boolean = False
Dim mimeStr As String
Dim i As Int
Dim n As Int = imap.NumMessages
For i = 1 To n

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

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

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

    '  Download the email by sequence number.
    success = imap.FetchEmail(False, i, bUid, email)

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

Next

'  Disconnect from the IMAP server.
success = imap.Disconnect
