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

$oImap = ObjCreate("Chilkat.Imap")

; Connect to an IMAP server.
; Use TLS
$oImap.Ssl = True
$oImap.Port = 993
Local $bSuccess = $oImap.Connect("imap.someMailServer.com")
If ($bSuccess <> True) Then
    ConsoleWrite($oImap.LastErrorText & @CRLF)
    Exit
EndIf

; Login
$bSuccess = $oImap.Login("myLogin","myPassword")
If ($bSuccess <> True) Then
    ConsoleWrite($oImap.LastErrorText & @CRLF)
    Exit
EndIf

; Select an IMAP mailbox
$bSuccess = $oImap.SelectMailbox("Inbox")
If ($bSuccess <> True) Then
    ConsoleWrite($oImap.LastErrorText & @CRLF)
    Exit
EndIf

; Set PeekMode so that downloaded messages are not
; automatically marked as seen.
$oImap.PeekMode = True

; The NumMessages property contains the number of messages 
; in the currently selected mailbox.
Local $iNumMsgs = $oImap.NumMessages
If ($iNumMsgs = 0) Then
    Exit
EndIf

Local $i
For $i = 1 To $iNumMsgs
    ; Download each email by sequence number (not UID)
Local $oEmail
    $oEmail = $oImap.FetchSingle($i,False)
    If ($oImap.LastMethodSuccess = False) Then
        ConsoleWrite($oImap.LastErrorText & @CRLF)
        Exit
    EndIf

    ; If desired, mark the email as SEEN.  There are two
    ; ways to do it:

    ; 1) Set the flag directly by using the sequence number
    ; Indicate that we are passing a sequence number and
    ; not a UID:
Local $bIsUid = False
    ; Set the SEEN flag = 1 to mark the email as SEEN,
    ; or set it to 0 to mark it as not-seen.
    $bSuccess = $oImap.SetFlag($i,$bIsUid,"SEEN",1)
    If ($bSuccess <> True) Then
        ConsoleWrite($oImap.LastErrorText & @CRLF)
        Exit
    EndIf

    ; 2) Alternatively, we can use the email object.
    ; When an email is downloaded from the IMAP server
    ; Chilkat will add a "ckx-imap-uid" header to the email.
    ; This makes it possible to know the UID associated with
    ; the email.  (This is not the sequence number, which may change
    ; from session to session, but the UID which does not change.
    ; The SetMailFlag method is identical to SetFlag, except
    ; it gets the UID from the ckx-imap-uid header.
    ; For example:
    $bSuccess = $oImap.SetMailFlag($oEmail,"SEEN",1)
    If ($bSuccess <> True) Then
        ConsoleWrite($oImap.LastErrorText & @CRLF)
        Exit
    EndIf

Next

; Disconnect from the IMAP server.
$bSuccess = $oImap.Disconnect()
