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

Dim imap As New Chilkat.Imap

' Use TLS

Dim success As Boolean = Await imap.ConnectAsync("imap.someMailServer.com")

' Login
success = Await imap.LoginAsync("myLogin","myPassword")
If (success <> True) Then

' Select an IMAP mailbox
success = Await imap.SelectMailboxAsync("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.

    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 = Await imap.DisconnectAsync()
