Dim imap As New Chilkat.Imap

' Connect to an IMAP server.
' Use TLS
imap.Ssl = True
imap.Port = 993
Dim success As Boolean = imap.Connect("imap.someMailServer.com")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Login
success = imap.Login("myLogin","myPassword")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
If (success <> True) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If



' The NumMessages property contains the number of messages in the selected mailbox.
Dim numToFetch As Integer = imap.NumMessages
' Download all the email in the Inbox.
Dim sa As Chilkat.StringArray
sa = imap.FetchSequenceAsMime(1,numToFetch)
If (imap.LastMethodSuccess = False) Then
    Debug.WriteLine(imap.LastErrorText)
    Exit Sub
End If


' Loop over the MIME strings contained within sa:
Dim i As Integer = 0
While i < sa.Count
    Dim strMime As String
    strMime = sa.GetString(i)

    ' Now you have the MIME source of this email...  

    i = i + 1
End While



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