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

loImap = CreateObject('Chilkat_9_5_0.Imap')

* Connect to an IMAP server.
* Use TLS
loImap.Ssl = 1
loImap.Port = 993
lnSuccess = loImap.Connect("imap.someMailServer.com")

    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Login
lnSuccess = loImap.Login("login","password")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Select an IMAP mailbox
lnSuccess = loImap.SelectMailbox("Inbox")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

lnFetchUids = 1

* The UID of each fetched email header is available 
* in the ckx-imap-uid header field.
