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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Imap')
loImap = CreateObject('Chilkat.Imap')

* Connect to an IMAP server.
* Use TLS
loImap.Ssl = 1
loImap.Port = 993
lnSuccess = loImap.Connect("imap.someMailServer.com")
IF (lnSuccess <> 1) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Login
lnSuccess = loImap.Login("myLogin","myPassword")
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

* We can choose to fetch UIDs or sequence numbers.
lnFetchUids = 1

* Fetch messages from the mailbox using a search criteria.
* This example finds NEW emails: these are emails that have the RECENT flag set, but not the SEEN flag:
loMessageSet = loImap.Search("NEW",lnFetchUids)
IF (loImap.LastMethodSuccess = 0) THEN
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* This example will download headers, and then download
* the full email for those emails sent from a contact
* in our database.

* When downloading headers, each email object contains
* (obviously) the headers, but the body will be missing.
* Also, attachments will not be included.  However, it is
* possible to get information about the attachments
* as well as the complete size of the email.

loBundle = loImap.FetchHeaders(loMessageSet)
IF (loImap.LastMethodSuccess = 0) THEN
    RELEASE loMessageSet
    ? loImap.LastErrorText
    RELEASE loImap
    CANCEL
ENDIF

* Loop over the email objects...
i = 0
lnNumEmails = loBundle.MessageCount
DO WHILE i < lnNumEmails
    loEmail = loBundle.GetEmail(i)

    * The sender's email address and name are available
    * in the From, FromAddress, and FromName properties.
    * If the sender is "Chilkat Support <support@chilkatsoft.com",
    * then the From property will hold the entire string.
    * the FromName property contains"Chilkat Support",
    * and the FromAddress property contains "support@chilkatsoft.com"
    ? loEmail.From
    ? loEmail.FromAddress
    ? loEmail.FromName

    * Assume at this point your code checks to see if the sender
    * is one in your contacts database.  If so, this is
    * the code you would write to download the entire
    * email and save it to a file.

    * The ckx-imap-uid header field is added when
    * headers are downloaded.  This makes it possible
    * to get the UID from the email object.
    lcUidStr = loEmail.GetHeaderField("ckx-imap-uid")
    lnUid = VAL(lcUidStr)

    loFullEmail = loImap.FetchSingle(lnUid,1)
    IF (loImap.LastMethodSuccess = 1) THEN
        * You may use the GenerateFilename method to
        * generate a unique filename...

        lcFilename = loFullEmail.GenerateFilename()

        * SaveEml saves the entire email, including attachments.
        lnSuccess = loFullEmail.SaveEml(lcFilename)
        RELEASE loFullEmail
    ENDIF

    ? "--"
    RELEASE loEmail

    i = i + 1
ENDDO

* Disconnect from the IMAP server.
lnSuccess = loImap.Disconnect()
